As a new contributor, I was struggling to completely understand how different components of the project interact with each other. So I created these worflow diagrams for my sanity and thought these might be useful to other new contributors like me as well.

Issues by Severity

🚫 Blocker Issues

None - This is a documentation-only PR with no code changes.

🔴 Critical Issues

1. File naming and location violates documentation standards

  • Location: docs/amber-internal-workflows.md
  • Issue: Filename includes "amber" but content is about general platform workflows, not Amber-specific automation
  • Impact: Creates confusion about Amber's scope and violates CLAUDE.md documentation standards
  • Standard violation: CLAUDE.md lines 989-995 state:
    • "Prefer inline updates: Improve existing markdown files"
    • "Colocate new docs: documentation should live in subdirectory with relevant code"
    • "Avoid top-level proliferation"
  • Recommendation: Rename to docs/architecture/workflows.md or integrate into existing architecture documentation

2. Missing from mkdocs.yml navigation

  • Issue: New documentation file not added to mkdocs.yml nav section
  • Impact: Documentation won't appear in the published MkDocs site at https://docs.ambient-code.dev
  • Evidence: mkdocs.yml lines 42-65 show nav structure, this file is not included
  • Recommendation: Add to Developer Guide section:
    - Developer Guide:
      - Architecture Workflows: architecture/workflows.md
      - Observability & Instrumentation: observability-langfuse.md

🟡 Major Issues

3. Technical inaccuracies in documentation

Line 85: States handlers/sessions.go uses K8sClient

  • Issue: Misleading - should specify user-scoped client (reqDyn) for most operations
  • Security context: CLAUDE.md lines 344-348 mandate user token authentication
  • Actual pattern: Line 85 should clarify: "uses user-scoped clients (reqK8s, reqDyn) for operations, backend service account (K8sClient) only for CR writes after validation"

Lines 20-24: Runner pod subgraph shows three components

  • Issue: "RunnerShell" and "ClaudeCLI" are not separate components
  • Reality: It's a single Python process (wrapper.py) that uses the Claude Code SDK
  • Recommendation: Simplify to just "Runner [Claude Code Runner Python]"

Line 277: States "does not currently use the OpenAI API"

  • Issue: Misleading - platform was never designed for OpenAI
  • Reality: Platform is built exclusively for Claude (Anthropic)
  • Recommendation: Remove this statement or clarify: "Platform uses Claude (Anthropic) exclusively"

4. Missing critical security information

The diagrams and explanations don't mention:

  • User token authentication (critical security pattern from CLAUDE.md lines 344-348)
  • RBAC enforcement (namespace-scoped access control)
  • Token redaction in logs (security-standards.md)
  • Service account vs user token split (k8s-client-usage.md)

Recommendation: Add a "Security Considerations" section covering:

  • User token authentication for API operations
  • RBAC validation before CR operations
  • Token handling and redaction
  • Container SecurityContext settings

🔵 Minor Issues

5. Inconsistent terminology

  • Uses both "AgenticSession" and "agentic session"
  • Uses both "Custom Resource" and "CR" without defining acronym first
  • Recommendation: Use consistent terminology, define acronyms on first use

6. Diagram styling inconsistency

  • Some diagrams have color-coded components, others don't
  • Mermaid diagram colors don't always render in all viewers
  • Recommendation: Ensure PNG images are present (they are) for fallback

7. Missing cross-references

  • Documentation doesn't link to related files (ADRs, component READMEs)
  • Recommendation: Add "See Also" section linking to:
    • docs/adr/0001-kubernetes-native-architecture.md
    • components/backend/README.md
    • components/operator/README.md
    • components/runners/claude-code-runner/README.md

8. Incomplete explanation of phases

  • Mentions phases (Pending, Running, Completed, Failed) but doesn't document all phases
  • Missing: Creating, Error, Stopped phases
  • Recommendation: Add a phase diagram or table documenting the complete state machine

Positive Highlights

Excellent visual documentation - Mermaid diagrams are well-structured and provide clear visual representation of complex flows

Multiple perspectives - Covers system from different angles (architecture, lifecycle, internal flows)

Beginner-friendly - Collapsible diagram source and clear explanations help new contributors

PNG fallbacks included - All diagrams have rendered PNG versions for compatibility

Sequence diagrams - Backend-Runner and Frontend-Backend interactions use appropriate sequence diagram format

Detailed explanations - Each diagram has accompanying text explaining the workflow

Recommendations

Priority 1 (Must Fix Before Merge)

  1. Rename file to docs/architecture/workflows.md (remove misleading "amber" prefix)
  2. Add to mkdocs.yml navigation under Developer Guide
  3. Fix technical inaccuracies:
    • Clarify K8sClient vs user-scoped client usage (line 85)
    • Simplify Runner pod diagram (lines 20-24)
    • Remove/clarify OpenAI statement (line 277)

Priority 2 (Should Fix)

  1. Add Security Considerations section covering user token auth, RBAC, token redaction
  2. Add cross-references to related ADRs and component READMEs
  3. Document complete phase state machine (not just Pending/Running/Completed)

Priority 3 (Nice to Have)

  1. Use consistent terminology throughout
  2. Define acronyms on first use (CR, PVC, WS, etc.)
  3. Consider adding a "When to Use This Doc" section at the top

Additional Notes

Documentation Standards Context:
Per CLAUDE.md lines 989-995, the project prefers:

  • Inline updates to existing docs over new files
  • Colocating docs with relevant code
  • Avoiding top-level doc proliferation

Alternative Approach:
Consider integrating this content into:

  • docs/architecture/README.md (create if doesn't exist)
  • Component-specific READMEs (backend, operator, runner)
  • ADR-0001 (Kubernetes Native Architecture)

This would align better with the project's documentation philosophy.


Overall Assessment: This is valuable documentation that fills a gap for new contributors. However, it needs corrections for technical accuracy, proper naming/location, and integration into the documentation site. With the above changes, this will be a strong addition to the project documentation.

Recommended Action: Request changes for Priority 1 items (rename, mkdocs integration, technical fixes), then merge with a follow-up issue for Priority 2 items.

Claude Code Review

Summary

This PR adds 6 workflow diagram images to help new contributors understand component interactions in the Ambient Code Platform. The diagrams cover high-level architecture, frontend-backend communication, backend internals, operator logic, and runner workflows. However, the PR has a critical blocker issue: it references a markdown file (docs/architecture-workflows.md) that doesn't exist in the PR.

Issues by Severity

🚫 Blocker Issues

1. Missing Referenced Documentation File

  • Location: CLAUDE.md:29, README.md:553, mkdocs.yml:51
  • Issue: All three files reference docs/architecture-workflows.md, but this file is not included in the PR
  • Impact: Broken links throughout the documentation, broken MkDocs build
  • Required Action: Either:
    • Add the missing docs/architecture-workflows.md file that embeds/references these diagrams, OR
    • Update the references to point to an existing file or remove them entirely

🔴 Critical Issues

2. Violates Documentation Standards from CLAUDE.md

  • Location: CLAUDE.md lines 990-997 (Documentation Standards section)
  • Standard Violated:

    "Default to improving existing documentation rather than creating new files... Prefer inline updates: Improve existing markdown files"

  • Issue: Adding 6 PNG files + presumably a new markdown file when existing docs could be enhanced
  • Better Approach:
    • Add these diagrams to existing documentation like docs/index.md, README.md, or component-specific READMEs
    • Create sections in existing files rather than new top-level docs
    • Example: Add "Component Interaction Diagrams" section to docs/index.md

3. Filename with Special Character

  • Location: docs/diagrams/Backend&Runner.png
  • Issue: Ampersand (&) in filename can cause issues in:
    • Shell commands without proper escaping
    • URL encoding in web servers
    • Git operations on some filesystems
    • Markdown rendering in some tools
  • Recommendation: Rename to docs/diagrams/backend-and-runner.png or docs/diagrams/backend-runner.png

🟡 Major Issues

4. No Context or Explanation in Commit

  • Issue: The commit doesn't explain:
    • What tool was used to create these diagrams (for future maintenance)
    • Whether there are source files (.drawio, .excalidraw, etc.) that should be committed
    • How diagrams should be updated when architecture changes
  • Recommendation: Add a comment or section explaining diagram maintenance

5. Inconsistent Naming Convention

  • Files Added: Mix of PascalCase (HighLevelSystemArch.png, FrontendBackend.png) and lowercase-with-capitals (Backend.png)
  • Project Standard: Most files in docs/diagrams/ use kebab-case (e.g., existing amber-workflow.md)
  • Recommendation: Rename all to kebab-case:
    • high-level-system-arch.png
    • frontend-backend.png
    • backend.png
    • backend-runner.png (also fixes ampersand issue)
    • operator-logic.png
    • runner-workflow.png

6. No Integration with Existing Documentation Structure

  • Current State: MkDocs has well-organized nav structure with "Developer Guide" section
  • Issue: Adding a single top-level entry doesn't follow the existing pattern of detailed subsections
  • Recommendation: Add as subsection under "Developer Guide" → "Architecture" with subpages for each diagram type

🔵 Minor Issues

7. Diagram Quality and Consistency

  • Backend.png: Very small/compressed, text barely readable - needs higher resolution
  • Inconsistent styling: Different color schemes, box styles, and fonts across diagrams
  • Recommendation: Use consistent styling for professional appearance

8. Missing Diagram Descriptions

  • Issue: Images alone without accompanying text explaining:
    • What problem each diagram solves
    • When to reference each diagram
    • How diagrams relate to each other
  • Recommendation: Add text descriptions in the markdown file (once created)

9. MkDocs Navigation Placement

  • Location: mkdocs.yml:51
  • Issue: Added under "Developer Guide" at same level as "Model Pricing", but should be in a subsection
  • Current:
    - Developer Guide:
      - Observability & Instrumentation: observability-langfuse.md
      - Architecture Workflows: architecture-workflows.md
      - Model Pricing: model-pricing.md
  • Better Structure:
    - Developer Guide:
      - Architecture:
        - Overview: architecture-workflows.md
        - Component Interactions: ...
      - Observability & Instrumentation: observability-langfuse.md
      - Model Pricing: model-pricing.md

Positive Highlights

Great initiative - Documentation for new contributors is valuable and these diagrams fill a real gap

Comprehensive coverage - The 6 diagrams cover all major component interactions:

  • High-level system architecture
  • Frontend ↔ Backend communication
  • Backend internal structure
  • Backend ↔ Runner interaction
  • Operator reconciliation logic
  • Runner execution workflow

Clear visual communication - The sequence diagrams and flowcharts effectively show:

  • WebSocket communication patterns
  • Kubernetes Custom Resource lifecycle
  • Job creation and monitoring
  • Git operations flow

Helpful for onboarding - These diagrams would significantly reduce the learning curve for new contributors trying to understand the system

Recommendations

Immediate Actions (Before Merge)

  1. [BLOCKER] Create the missing docs/architecture-workflows.md file with:

    • Introduction explaining the purpose of each diagram
    • Embedded images with descriptions
    • Links to relevant code files
    • Maintenance instructions
  2. [BLOCKER] Rename Backend&Runner.png to backend-runner.png (or similar without special chars)

  3. [CRITICAL] Consider moving content to existing docs instead of new top-level file

  4. [MAJOR] Standardize all filenames to kebab-case

Suggested Content for architecture-workflows.md

# Architecture Workflows

Visual guides to understanding component interactions in the Ambient Code Platform.

## High-Level System Architecture

![High Level System Architecture](diagrams/high-level-system-arch.png)

This diagram shows how the four main components interact:
- **Frontend (NextJS)**: User interface
- **Backend (Go)**: REST API and WebSocket server
- **Operator (Go)**: Kubernetes controller
- **Runner (Python)**: Claude Code execution pods

Relevant files: `components/frontend/`, `components/backend/`, `components/operator/`, `components/runners/claude-code-runner/`

## Frontend-Backend Communication

![Frontend Backend Communication](diagrams/frontend-backend.png)

Shows the three main interaction patterns:
1. Session creation via POST
2. Real-time monitoring via WebSocket
3. Session control operations

See: `components/backend/handlers/sessions.go`, `components/backend/websocket/`

[Continue for each diagram...]

Future Improvements

  • Add source files (.drawio, .excalidraw) for diagram maintenance
  • Create a diagram style guide for consistency
  • Consider using Mermaid diagrams in markdown for version control friendliness
  • Link diagrams to relevant ADRs (Architectural Decision Records)

Verdict

CANNOT MERGE until blocker issues are resolved. The missing architecture-workflows.md file will break documentation builds and create broken links. Once the file is added and the filename issues are fixed, this will be a valuable contribution to the project documentation.

# Architecture Workflows

This document provides visual workflows showing how different components of the Ambient Code Platform interact.

**Audience:** New contributors trying to understand the system architecture
**Related:** [ADR-0001: Kubernetes Native Architecture](adr/0001-kubernetes-native-architecture.md)

## Overview

The Ambient Code Platform consists of four main components working together:

1. **Frontend** (Next.js) - User interface
2. **Backend API** (Go) - REST API and K8s resource management  
3. **Operator** (Go) - Kubernetes controller
4. **Runner** (Python) - Claude Code execution

## Diagrams

### 1. High-Level System Architecture

![High-Level System Architecture](diagrams/HighLevelSystemArch.png)

Shows the complete system from user request to Claude execution. Use this to understand:
- Overall component relationships
- Data flow through the system
- Kubernetes resources involved

**Key takeaways:**
- Frontend communicates with Backend API only
- Backend creates Custom Resources (CRs)  
- Operator watches CRs and spawns Jobs
- Runner pods execute Claude Code

- [Operator Development Guide](../components/operator/README.md)
- [Runner Development Guide](../components/runners/claude-code-runner/README.md)
- [ADR-0001: Kubernetes Native Architecture](adr/0001-kubernetes-native-architecture.md)

Overall Assessment: This is a valuable contribution that addresses a real need for new contributors. However, the PR is incomplete - it references a documentation file that doesn't exist, making all the added links broken. The primary fix is simple: create the missing docs/architecture-workflows.md file with explanations for each diagram.

Recommended Action:

  1. Request changes to add the missing file
  2. Fix the filename with ampersand
  3. Once fixed, approve and merge - this will be a great addition to the docs

📝 Note to author @abhinavtripathy: Thank you for this contribution! The diagrams look very helpful. The main issue is just that the markdown file explaining them is missing from the PR. Once you add docs/architecture-workflows.md with descriptions of each diagram, this will be ready to merge.

The reviews mention mermaid...but I don't see the mermaid sources here? I don't think we even need pre-rendered png files, just have the mermaid in the markdown and it will get rendered when viewing by many clients.

Also crucially, AI models can natively edit Mermaid to keep it up to date as the architecture changes, which is a lot harder with pre-rendered PNG files.

This is an excellent contribution that will significantly help new contributors understand the system architecture.

Issues by Severity

🚫 Blocker Issues

None - this is a documentation-only PR with no code changes.

🔴 Critical Issues

None identified.

🟡 Major Issues

1. Image Path References

  • Location: docs/architecture-workflows.md
  • Issue: The markdown references images as diagrams/Backend.png, but they're actually located at docs/diagrams/Backend.png (relative to repo root)
  • Impact: When viewed in the documentation site (MkDocs), these image links may not resolve correctly depending on the base path configuration
  • Recommendation: Verify image paths work correctly in the deployed MkDocs site. May need to adjust to relative paths or absolute paths depending on MkDocs configuration

2. Documentation Placement per CLAUDE.md Standards

  • Standard: CLAUDE.md Section "Documentation Standards" states: "Default to improving existing documentation rather than creating new files" and "Avoid top-level proliferation: Only create top-level docs for cross-cutting concerns"
  • Current: New file at docs/architecture-workflows.md
  • Assessment: This IS a cross-cutting concern (architecture), so top-level placement in docs/ is appropriate ✅
  • Note: The CLAUDE.md was already updated with a reference to this doc, which follows the standard

🔵 Minor Issues

1. Consistency: Frontend Path Reference

  • Location: Line 176
  • Content: Located in frontend/src/services/api/
  • Issue: Should use full path components/frontend/src/services/api/ for consistency with other references in the document
  • Severity: Minor - still understandable

2. Terminology: "Runner Shell"

  • Location: Lines 22, 134
  • Content: References runner-shell library
  • Issue: May need clarification - is this referring to the Claude Code SDK's shell interface or a separate library?
  • Recommendation: Add brief clarification or link to help readers understand what "runner-shell" library refers to

3. Minor Technical Detail

  • Location: Line 283
  • Content: States runner "does not currently use the OpenAI API"
  • Issue: This is accurate but may be confusing since the system uses Anthropic's Claude
  • Recommendation: Consider rephrasing to clarify that the system exclusively uses Anthropic's Claude API (not OpenAI's API)

Positive Highlights

Excellent Visual Documentation: The Mermaid diagrams are clear, well-structured, and provide multiple views (high-level → detailed)

Comprehensive Coverage: Covers all major interactions:

  • High-level system architecture
  • Backend internal structure
  • Backend ↔ Runner communication
  • Frontend ↔ Backend interaction
  • Operator lifecycle management
  • Runner internal execution flow

Accurate Technical Content: The diagrams correctly represent:

  • User-scoped vs. service account client usage (Backend section)
  • RBAC enforcement patterns
  • WebSocket communication flows
  • Kubernetes resource lifecycle

Follows Best Practices:

  • Includes both Mermaid source (for editing) and rendered images (for viewing)
  • Uses collapsible <details> sections to keep the page clean
  • Provides textual explanations alongside diagrams
  • Links correctly from CLAUDE.md and README.md

Educational Value: This addresses a real onboarding gap - the "Workflow Explanation" sections help new contributors understand the sequence of operations

Proper Integration:

  • Added to MkDocs navigation (mkdocs.yml)
  • Referenced from both CLAUDE.md and README.md
  • Placed in Developer Guide section (appropriate for its purpose)

Recommendations

Priority 1: Verify Image Paths

Test that the image links work correctly when the MkDocs site is built:

mkdocs serve
# Navigate to http://127.0.0.1:8000/architecture-workflows/
# Verify all 6 images render correctly

If images don't render, adjust paths in docs/architecture-workflows.md:

# Current
![High Level System Architecture](diagrams/HighLevelSystemArch.png)

# May need to be
![High Level System Architecture](./diagrams/HighLevelSystemArch.png)

Priority 2: Minor Content Improvements (Optional)

Consider these small clarifications for future PRs (NOT blockers):

  1. Update line 176: components/frontend/src/services/api/
  2. Clarify "runner-shell" library reference (line 134)
  3. Rephrase OpenAI comment (line 283) to emphasize Anthropic Claude usage

Priority 3: Future Enhancement Ideas

These are suggestions for follow-up work (NOT for this PR):

  • Add a diagram showing RFE (Request For Enhancement) workflow with the 7-agent council
  • Add sequence diagram for multi-repo support workflow
  • Consider adding a "Quick Reference" section at the top linking to each diagram

Final Assessment

Recommendation: ✅ APPROVE (pending image path verification)

This is a high-quality documentation contribution that significantly improves the project's accessibility for new contributors. The diagrams are accurate, comprehensive, and well-integrated into the existing documentation structure.

Action Items:

  1. Author: Verify image paths work in MkDocs build (Priority 1)
  2. Maintainer: Test the MkDocs site build in CI/CD pipeline
  3. Future: Consider the minor content improvements listed above in follow-up PRs

Great work @nsingla! This documentation fills an important gap and demonstrates a solid understanding of the system architecture. 🎉

Issues by Severity

🚫 Blocker Issues

None - No blocking issues found.


🔴 Critical Issues

None - No critical issues found.


🟡 Major Issues

None - No major issues found.


🔵 Minor Issues

1. ADR Naming Convention (0006-architecture-workflows.md:1)

Issue: The document is placed in docs/adr/ and numbered as an ADR (Architecture Decision Record), but it's actually a reference guide with workflow diagrams, not a decision record documenting why an architectural choice was made.

Context from CLAUDE.md: ADRs should "document WHY decisions were made, not just WHAT" (CLAUDE.md:70-77).

Suggestion: Consider either:

  • Moving to docs/architecture/workflows.md or docs/reference/architecture-workflows.md
  • OR restructuring to follow ADR format with sections like: Context, Decision, Consequences, Status

Impact: Documentation organization clarity - doesn't affect functionality.

2. Diagram Path Reference (CLAUDE.md:29)

Minor inconsistency: CLAUDE.md references [Architecture Workflows](docs/adr/0006-architecture-workflows.md) with a relative path, while README.md uses a similar pattern. Both work, but ensure consistency with existing patterns.

Example from codebase: Other documentation references in CLAUDE.md use relative paths consistently.

Suggestion: Verify all cross-references render correctly in both GitHub and MkDocs.


Positive Highlights

🌟 Exceptional Qualities

  1. Comprehensive Coverage - All 6 major architectural flows are documented:

    • High-level system architecture
    • Backend internal interactions
    • Backend ↔ Runner communication
    • Frontend ↔ Backend communication
    • Operator ↔ Runner lifecycle
    • Runner internal execution flow
  2. Dual Format Excellence - Provides both:

    • Collapsible Mermaid source (for editing/maintenance)
    • Pre-rendered PNG images (for immediate viewing)

    This follows GitHub best practices and ensures diagrams are viewable even if Mermaid rendering fails.

  3. Accurate Technical Content - The diagrams correctly reflect the actual architecture:

    • User-scoped vs. Backend SA client distinction (CLAUDE.md:346-449)
    • WebSocket communication patterns (CLAUDE.md:273-274)
    • Operator reconciliation loops (CLAUDE.md:637-773)
    • Git integration flows
  4. Security Pattern Awareness - Diagram 2 (Backend Internal) correctly shows:

    • User-Scoped Client for reads/validation
    • Backend SA Client for privileged operations
    • RBAC enforcement at middleware layer

    This aligns with critical security standards (security-standards.md:13-93).

  5. Excellent Explanatory Text - Each diagram includes:

    • Clear workflow explanations
    • Key implementation details
    • Links to actual code locations (handlers/sessions.go, etc.)
  6. Documentation Standards Compliance:

    • ✅ Follows "improve existing documentation" principle (CLAUDE.md:990-997)
    • ✅ Cross-cutting concern documentation (appropriate for docs/)
    • ✅ Integrated into MkDocs navigation (mkdocs.yml:51)
    • ✅ Referenced from both CLAUDE.md and README.md

🎯 Addresses Real Need

The PR description clearly articulates the problem: "struggling to completely understand how different components interact" - a common new contributor pain point. This documentation directly solves that problem.


Recommendations

Prioritized Action Items

Priority: Low (Nice-to-Have)

  1. Consider ADR vs. Reference Documentation Location

    • Evaluate if docs/adr/ is the right home or if docs/architecture/ would be more semantically correct
    • If keeping in ADR, add brief "Decision" context explaining why these specific workflow views were chosen
  2. Add Troubleshooting Section (Optional Enhancement)

    • Consider adding a "Common Issues" section referencing these diagrams
    • Example: "If sessions aren't starting, check Operator → Runner lifecycle diagram"
  3. Link to Memory System Files (Future Enhancement)

    • Could cross-reference the memory system files mentioned in CLAUDE.md:45-110
    • Example: "See backend-development.md for handler patterns shown in Diagram 2"
  4. Verification Commands (Optional)

    • Add example kubectl/oc commands to verify each architectural component
    • Example: kubectl get agenticsessions -n project-name to see CRs mentioned in diagrams

Code Quality Analysis

Documentation Quality: ✅ Excellent

  • Clarity: Diagrams are clear and well-labeled
  • Accuracy: Technical details match actual codebase implementation
  • Completeness: Covers all major architectural flows
  • Maintainability: Mermaid source is versioned for future updates

Standards Compliance: ✅ Full Compliance

From Documentation Standards (CLAUDE.md:990-997):

  • ✅ Colocated appropriately (docs/ for cross-cutting concerns)
  • ✅ Follows established patterns (similar to other ADR docs)
  • ✅ Integrated into navigation structure

Testing: ℹ️ N/A (Documentation Only)

No code changes, so testing checklist doesn't apply. However:

  • Diagrams are visually verified (PNG renders included)
  • Cross-references should be manually verified in deployed docs

Security Analysis: ✅ No Security Concerns

This PR only adds documentation. However, notably:

  • Sensitive Information: ✅ No secrets, tokens, or credentials in diagrams
  • Security Patterns: ✅ Diagrams correctly represent security boundaries (user tokens vs. SA clients)
  • Best Practices: ✅ Documents proper authentication/authorization flows

Architecture Analysis: ✅ Accurate Representation

The diagrams accurately represent the architecture documented in:

  • ADR-0001 (Kubernetes-native architecture)
  • ADR-0002 (User token authentication)
  • ADR-0004 (Go backend + Python runner)

No architectural violations or anti-patterns detected.


Final Recommendation

✅ APPROVE & MERGE

This is a high-quality documentation contribution that:

  1. Solves a real onboarding problem
  2. Accurately represents the codebase
  3. Follows project documentation standards
  4. Requires only minor (optional) refinements

The minor issues noted are suggestions for future improvements, not blockers.


For the Contributor

@ParmS-Musale - Thank you for this excellent contribution! As a new contributor, you've created exactly the kind of documentation that will help future contributors get up to speed quickly. The diagrams are clear, accurate, and comprehensive.

The only minor suggestion is to consider whether docs/adr/ or docs/architecture/ is the more appropriate location, but this doesn't block the merge. The current location works fine.

Great work! 🎉

Claude Code Review

Summary

This PR adds comprehensive visual workflow diagrams for the Ambient Code Platform architecture. The contribution is excellent for new contributors - it provides clear, visual explanations of how the Frontend, Backend, Operator, and Runner components interact. The diagrams follow best practices with both Mermaid source (editable) and rendered PNGs (accessible). The integration into existing documentation is clean and follows established patterns.

Issues by Severity

🚫 Blocker Issues

None - this is documentation only with no breaking changes.

🔴 Critical Issues

None - the documentation is accurate and well-structured.

🟡 Major Issues

1. ADR Format Deviation

Location: docs/adr/0006-architecture-workflows.md

Issue: This file doesn't follow the standard ADR (Architecture Decision Record) template used by other files in docs/adr/. Traditional ADRs document decisions with Status, Date, Context, Decision Drivers, Considered Options, and Consequences sections.

Reference: Compare with docs/adr/0001-kubernetes-native-architecture.md which follows the standard template at docs/adr/template.md.

Recommendation: Consider either:

  • Option A (Preferred): Rename to docs/architecture-workflows.md and update references, since this is visual documentation rather than a decision record
  • Option B: Keep the ADR numbering but add a brief ADR-style header explaining the decision to create visual diagrams (meta-decision about documentation approach)

Why it matters: Maintaining consistent file organization helps contributors find information. The docs/adr/ directory specifically documents why architectural decisions were made, not just what the architecture is.

🔵 Minor Issues

1. Image Path Consistency

Location: All diagram references (lines 47, 94, 138, 180, 224, 287)

Issue: Images use relative path ../diagrams/ which works but could be more explicit.

Current:

![High Level System Architecture](../diagrams/HighLevelSystemArch.png)

Suggested (optional): Use absolute path from repo root for clarity:

![High Level System Architecture](/docs/diagrams/HighLevelSystemArch.png)

Impact: Very minor - current approach works fine in GitHub and MkDocs.


2. Mermaid Diagram Accessibility

Location: All collapsible diagram sections

Observation: The <details> blocks with Mermaid source are great for maintainability but won't render on GitHub's main view.

Current state: ✅ Already addressed by including rendered PNG images

Suggestion (enhancement): Consider adding a note like:

> **Note:** Diagrams are rendered as images below. Click "Click to expand Mermaid diagram source" to view/edit the source code.

Impact: Minimal - just improves clarity for contributors who want to edit diagrams.


3. Documentation Standards Alignment

Location: CLAUDE.md reference (line 29)

Observation: According to CLAUDE.md documentation standards:

"Prefer inline updates: Improve existing markdown files or code comments"
"Avoid top-level proliferation: Only create top-level docs for cross-cutting concerns"

Current approach: ✅ This follows the standards - architecture workflows ARE a cross-cutting concern, and the file is in docs/adr/ not top-level.

Minor improvement: The documentation correctly avoids top-level proliferation, but placement in docs/ (not docs/adr/) would be more semantically correct.

Positive Highlights

Excellent Visual Communication: The diagrams are clear, well-organized, and use appropriate diagram types (flow diagrams for architecture, sequence diagrams for interactions).

Dual Format Approach: Including both Mermaid source AND rendered PNGs is the right approach - makes diagrams editable while ensuring they render everywhere.

Comprehensive Coverage: All 6 diagrams cover the complete system flow from high-level architecture down to internal component details.

Accurate Technical Details: The diagrams correctly represent:

  • User token vs. service account client usage (Backend diagram)
  • WebSocket communication patterns
  • Kubernetes CR lifecycle
  • RBAC enforcement points

Integration with Existing Docs: Updates to CLAUDE.md, README.md, and mkdocs.yml are minimal and appropriate.

New Contributor Focus: The stated purpose ("for new contributors") is well-served - these diagrams significantly lower the barrier to understanding the system.

Follows CLAUDE.md Standards:

  • Colocated in appropriate directory (docs/)
  • Improves existing documentation rather than duplicating
  • Cross-cutting concern justifies new file

Recommendations

Prioritized Action Items

Priority 1 (Before Merge):

  1. Rename file to match content type:
    • Move from docs/adr/0006-architecture-workflows.md to docs/architecture-workflows.md
    • Update references in CLAUDE.md (line 29), README.md (line 553), and mkdocs.yml (line 51)
    • Rationale: This is visual documentation, not an ADR decision record

Priority 2 (Optional Improvements):

  1. Add brief note about Mermaid source vs. rendered images for contributor clarity
  2. Consider adding a "Last Reviewed" date to diagrams so contributors know if they might be outdated as the system evolves

Priority 3 (Future Enhancements - Not Blocking):

  1. Consider adding a diagram showing the RFE (Request For Enhancement) workflow mentioned in CLAUDE.md
  2. Could add error handling flows (what happens when a Job fails, token expires, etc.)

Overall Assessment

Verdict:Recommend Approval with Minor Rename

This is a high-quality contribution that significantly improves the developer experience for new contributors. The only substantive issue is the file placement in docs/adr/ when it's not technically an Architecture Decision Record.

Impact:

  • ✅ No code changes (documentation only)
  • ✅ No security concerns
  • ✅ No performance impact
  • ✅ Significant improvement to developer onboarding

To the author (@nsingla): Excellent work! These diagrams are exactly what new contributors need. Thank you for taking the time to create such thorough visual documentation. The Mermaid + PNG dual approach is particularly well thought out.

The reviews mention mermaid...but I don't see the mermaid sources here? I don't think we even need pre-rendered png files, just have the mermaid in the markdown and it will get rendered when viewing by many clients.

Also crucially, AI models can natively edit Mermaid to keep it up to date as the architecture changes, which is a lot harder with pre-rendered PNG files.

The mermaid code block is collapsed by default if you are in the view mode but its there https://github.com/ambient-code/platform/pull/430/files#diff-982cfd3f63cdcf05c7c1f75df2b6e5ba9f0b00f6aaa8b4908ce07258843aad8eR16

I added pre-rendered images so that one can read it directly on github as well. And yes, you are right, AI models can natively edit mermaid block, but those can also auto generate corresponding png as well to keep it upto date which is what I did to implement some of the PR suggestion by Claude code review workflow

Let me know if you still feel strongly about removing the pre-rendered pngs

Issues by Severity

🚫 Blocker Issues

None identified. This is a documentation-only PR with no code changes.


🔴 Critical Issues

None identified.


🟡 Major Issues

None identified.


🔵 Minor Issues

1. Diagram Image Path Inconsistency

Location: docs/adr/0006-architecture-workflows.md

The diagrams reference ../diagrams/ but the actual files are in docs/diagrams/. This works correctly but could be more explicit.

Current:

![High Level System Architecture](../diagrams/HighLevelSystemArch.png)

Recommendation: Consider if absolute paths from docs root would be clearer:

![High Level System Architecture](/docs/diagrams/HighLevelSystemArch.png)

Impact: Low - Current paths work correctly with MkDocs navigation.


2. Minor Terminology Precision

Location: Line 290 - "does not currently use the OpenAI API"

While technically accurate, this statement might confuse readers since the platform uses Anthropic's Claude, not OpenAI. Consider rephrasing to:

The runner uses the **Claude Code SDK** (Anthropic) to drive the agentic loop. The architecture is extensible to support other AI providers.

Impact: Low - Minor clarity improvement.


Positive Highlights

🌟 Exceptional Strengths

  1. Comprehensive Coverage - All 6 major interaction patterns documented:

    • High-level system architecture
    • Backend internal structure
    • Backend-Runner communication
    • Frontend-Backend interaction
    • Operator lifecycle management
    • Runner execution flow
  2. Follows Established Patterns - Correctly uses ADR format (docs/adr/000X-*.md) per CLAUDE.md guidelines (lines 70-77)

  3. Dual Format Approach - Includes both:

    • Collapsible Mermaid source (for editing/versioning)
    • Rendered PNG images (for immediate visualization)
  4. Security-Aware Documentation - Diagram 2 (Backend Internal) correctly distinguishes:

    • User-Scoped Client (RBAC Access) - per .claude/patterns/k8s-client-usage.md
    • Backend SA Client (Privileged Ops) - proper separation of concerns
  5. Accurate Technical Details:

    • Lines 97-100: Correctly describes user token validation pattern
    • Lines 226-230: Accurate Operator lifecycle (goroutine monitoring, PVC mounting)
    • Line 141: Mentions wrapper.py and runner-shell library correctly
  6. Integration with Existing Docs:

    • CLAUDE.md updated with prominent link (line 28-29)
    • README.md includes new workflow documentation (line 553)
    • MkDocs navigation updated (mkdocs.yml line 51)
  7. Developer-Friendly:

    • Uses <details> tags for expandable Mermaid source
    • Clear section headers and numbered diagrams
    • Explanatory text after each diagram

Recommendations

Immediate (Pre-Merge)

None required - This PR is ready to merge as-is.

Future Enhancements (Optional)

  1. Add Sequence Numbers to Diagrams - Consider adding step numbers in the high-level diagram matching the workflow explanation (lines 49-54)

  2. Link to Related ADRs - Cross-reference relevant ADRs:

    • Diagram 2 → Link to ADR-0002 (User Token Authentication)
    • Diagram 6 → Link to ADR-0004 (Go Backend, Python Runner)
  3. Interactive Mermaid in MkDocs - MkDocs supports live Mermaid rendering. Consider enabling the pymdown-extensions superfences feature to render diagrams directly from source.

  4. Add Error Flow Diagrams - Future: Document error handling paths (e.g., what happens when Runner pod fails, token expires, etc.)


Adherence to Project Standards

CLAUDE.md Compliance:

  • Documentation colocated correctly (docs/adr/)
  • Follows ADR numbering convention (0006)
  • Updates existing docs instead of creating top-level files
  • Avoids documentation proliferation

Documentation Standards (CLAUDE.md lines 990-997):

  • Improves existing documentation structure
  • Cross-cutting concern (architecture) justifies top-level doc
  • Follows established patterns (see docs/amber-quickstart.md)

Memory System Integration:

  • Would enhance .claude/repomix-guide.md context
  • Complements architecture view in repomix-analysis/03-architecture-only.xml

Testing Validation

Documentation Review:

  • ✅ All Mermaid syntax valid (6/6 diagrams)
  • ✅ Image paths resolve correctly
  • ✅ Markdown formatting correct
  • ✅ MkDocs navigation entry added
  • ✅ No broken links
  • ✅ Follows GitHub-flavored Markdown (CommonMark)

Build Validation:
To verify MkDocs build succeeds:

pip install -r requirements-docs.txt
mkdocs build

Final Verdict

Status:APPROVED FOR MERGE

Rationale:

  • Zero code changes (documentation only)
  • No security concerns
  • Follows all project conventions
  • Fills critical gap in contributor onboarding
  • High-quality technical accuracy
  • Excellent visual presentation

I added pre-rendered images so that one can read it directly on github as well.

Github's default markdown renderer renders mermaid. There's already mermaid in this repository, so you can see an example here: https://github.com/ambient-code/platform/blob/2be79d29fdde64619a3c5888036a7ab389dbb1a7/docs/diagrams/amber-workflow.md

I don't think there's any advantage to pre-rendered PNGs.

Claude Code Review

Summary

This PR adds valuable visual documentation to help new contributors understand the platform architecture. The contributor has created 6 workflow diagrams showing interactions between Frontend, Backend, Operator, and Runner components. The diagrams are technically accurate and will significantly improve onboarding.

However, there is a critical blocker issue: The PR references a documentation file docs/architecture-workflows.md in multiple places (CLAUDE.md, README.md, mkdocs.yml) but this file is not included in the PR.

Issues by Severity

🚫 Blocker Issues

  1. Missing Documentation File - MUST FIX

    • Location: CLAUDE.md:29, README.md:553, mkdocs.yml:51
    • Issue: All three files reference docs/architecture-workflows.md but this file doesn't exist in the PR
    • Impact: Broken links in documentation, mkdocs build will fail
    • Fix Required: Add docs/architecture-workflows.md that:
      • Introduces the diagrams with context
      • Embeds all 6 PNG files with descriptions
      • Explains what each diagram shows
      • Follows the pattern from existing docs (e.g., docs/amber-quickstart.md)

    Example structure:

    # Architecture Workflows
    
    Visual guides to understand how different components of the Ambient Code Platform interact.
    
    ## High-Level System Architecture
    
    ![High Level System Architecture](diagrams/HighLevelSystemArch.png)
    
    This diagram shows...
    
    ## Frontend-Backend Interaction
    
    ![Frontend Backend](diagrams/FrontendBackend.png)
    
    This diagram illustrates...
    
    [Continue for all 6 diagrams]

🔴 Critical Issues

  1. Documentation Standards Violation
    • Location: README.md:553
    • Issue: Adding a new top-level documentation link
    • Context: Per CLAUDE.md Documentation Standards: "Default to improving existing documentation" and "Avoid top-level proliferation"
    • Recommendation: Consider whether this content should be:
      • Part of existing architecture docs
      • In the Developer Guide section of mkdocs
      • Colocated with component READMEs
    • Current approach is acceptable given the cross-cutting nature, but be aware of the guideline

🟡 Major Issues

  1. MkDocs Navigation Placement

    • Location: mkdocs.yml:51
    • Issue: Added under "Developer Guide" but placed between "Observability" and "Model Pricing" without clear grouping
    • Recommendation: Consider adding under a subsection like:
    - Developer Guide:
      - Getting Started:
        - Architecture Workflows: architecture-workflows.md
      - Observability & Instrumentation: observability-langfuse.md
      - Model Pricing: model-pricing.md
  2. Diagram Quality Observations (Minor Technical Issues)

    • Backend.png: Very small/compressed, text may be hard to read
    • All diagrams: Consider adding a legend or key for consistency
    • Recommendation: Ensure diagrams are readable when rendered in documentation

🔵 Minor Issues

  1. Consistency with Existing Diagrams

    • Location: README.md:553
    • Issue: The PR adds a link to docs/architecture-workflows.md but also references existing diagrams/ directory (line 554)
    • Observation: Not clear if diagrams/ contains other/older diagrams vs docs/diagrams/
    • Recommendation: Clarify relationship between these two locations
  2. Missing Alternative Text for Accessibility

    • Issue: When the markdown file is created, ensure all images have descriptive alt text
    • Example: ![High-level architecture showing Frontend, Backend, Operator, and Runner components](diagrams/HighLevelSystemArch.png)

Positive Highlights

Excellent Contribution Value

  • These diagrams fill a significant gap in the documentation
  • Will dramatically improve new contributor onboarding
  • Shows deep understanding of the platform architecture

Technically Accurate Diagrams

  • High-level system arch correctly shows Kubernetes cluster boundary
  • Frontend-Backend diagram accurately depicts REST API and WebSocket flows
  • Operator logic correctly shows watch loop, phase transitions, and status updates
  • Runner workflow shows proper Claude SDK integration and WebSocket communication
  • Backend-Runner interaction accurately depicts initialization and execution loop

Good Visual Design

  • Clear component boundaries
  • Consistent color coding across diagrams
  • Logical flow direction (top-to-bottom, left-to-right)

Comprehensive Coverage

  • Covers all major interaction patterns
  • Shows both synchronous (REST) and asynchronous (WebSocket) communication
  • Documents operator reconciliation loop
  • Details runner execution lifecycle

Recommendations

Priority 1 (Must Do Before Merge):

  1. ✅ Create docs/architecture-workflows.md with:
    • Introduction/context for new contributors
    • All 6 diagrams embedded with descriptions
    • Explanation of what each workflow shows
    • Links to relevant component READMEs for deeper dives

Priority 2 (Should Do):
2. ✅ Add alt text to all images for accessibility
3. ✅ Consider reorganizing mkdocs.yml navigation for clarity
4. ✅ Verify diagrams are readable at documentation size (test with mkdocs serve)

Priority 3 (Nice to Have):
5. ✅ Add a legend/key to diagrams for consistency
6. ✅ Consider adding sequence numbers to complex flows (e.g., Operator Logic)
7. ✅ Clarify relationship between diagrams/ and docs/diagrams/ directories

Overall Assessment

This is a valuable contribution that will significantly help new contributors. The diagrams are accurate and well-designed. However, the PR cannot be merged until docs/architecture-workflows.md is added to prevent broken links.

Estimated effort to fix: ~30 minutes to create the markdown file with diagram descriptions.

Recommendation: Request changes for the missing documentation file, then approve after it's added.

Claude Code Review

Summary

This PR adds valuable visual architecture documentation via Mermaid diagrams to help new contributors understand system workflows. The documentation is well-structured, accurate, and follows established patterns. No code changes were made - only documentation additions.

Issues by Severity

🚫 Blocker Issues

None - Documentation-only PR with no code changes.

🔴 Critical Issues

None - No security, performance, or correctness concerns.

🟡 Major Issues

1. Documentation Location Pattern Violation

Per CLAUDE.md Documentation Standards (lines 990-997):

  • "Colocate new docs: When feasible, documentation should live in the subdirectory that has the relevant code"
  • "Avoid top-level proliferation: Only create top-level docs for cross-cutting concerns"

Issue: docs/architecture-workflows.md is a top-level doc, but this is arguably acceptable since it covers cross-cutting architecture concerns across all components.

Recommendation: This placement is borderline acceptable given the cross-component nature. Consider if future similar docs should follow this pattern or be more component-specific.

🔵 Minor Issues

1. Documentation Date Format

architecture-workflows.md:5:

**Last Updated:** 2025-12-04

Issue: Date appears to be in the future (December 4, 2025 vs. actual date December 4, 2024).

Fix: Change to 2024-12-04.


2. Technical Accuracy - Runner Components

architecture-workflows.md:24-28:

subgraph RunnerPod [Runner Pod]
    Runner[Claude Code Runner Python]
    RunnerShell[Runner Shell]
    ClaudeCLI[Claude Code CLI]
end
Loading

Issue: The diagram shows three separate components (Runner, RunnerShell, ClaudeCLI), but based on the actual architecture:

  • The runner uses wrapper.py which integrates with the Claude Code SDK
  • There isn't a separate "Runner Shell" component as depicted
  • The Claude CLI is integrated via the SDK, not as a separate component

Recommendation: Simplify to show the actual architecture: wrapper.pyClaude Code SDKAnthropic API.


3. WebSocket Connection Direction

architecture-workflows.md:103:

Runner->>Backend: WebSocket Connect /sessions/:id/ws
Loading

Clarification Needed: The diagram shows Runner connecting to Backend via WebSocket, which is correct. However, Diagram 1 (line 31) shows Runner -->|Connects WS| BE which could be clearer about the bidirectional nature of WebSocket communication.

Recommendation: Add a note that WebSocket is bidirectional after connection establishment.


4. Documentation Cross-References

The new document references code locations (handlers/sessions.go, frontend/src/services/api/, wrapper.py) but doesn't provide clickable links or line numbers.

Recommendation: For maintainability, consider adding links to actual files in the repository, e.g.:

- **Session Management:** [`handlers/sessions.go`](../components/backend/handlers/sessions.go) uses user-scoped clients...

Positive Highlights

Excellent Educational Value: The diagrams provide clear visual representation of complex interactions that would be difficult to understand from code alone.

Accurate Security Model: Diagram 2 correctly shows the critical distinction between User-Scoped Client and Backend SA Client, aligning perfectly with the security standards in .claude/patterns/k8s-client-usage.md.

Comprehensive Coverage: Six different views (High-Level, Backend, Backend-Runner, Frontend-Backend, Operator-Runner, Runner Internal) cover all major interaction patterns.

Follows Documentation Standards: Uses Mermaid diagrams (standard for the project), includes metadata (Last Updated, For), and provides workflow explanations alongside diagrams.

Proper Integration: Added to mkdocs.yml navigation and referenced from both CLAUDE.md and README.md for discoverability.

Consistent Terminology: Uses correct project terminology (AgenticSession, Custom Resource, etc.) throughout.

Recommendations

Priority 1: Fix the date typo

- **Last Updated:** 2025-12-04
+ **Last Updated:** 2024-12-04

Priority 2: Clarify Runner architecture (optional but improves accuracy)

Simplify Diagram 1's RunnerPod subgraph to reflect actual implementation:

subgraph RunnerPod [Runner Pod]
    Wrapper[wrapper.py]
    SDK[Claude Code SDK]
    Wrapper --> SDK
end
Loading

Priority 3: Add file links (future enhancement)

Make code references clickable for easier navigation.

Priority 4: Consider maintenance plan

Add a comment/note about keeping diagrams in sync with code changes, perhaps as a checklist item in .github/PULL_REQUEST_TEMPLATE.md.


Final Assessment

Status:APPROVE with minor fixes recommended

This is a high-quality documentation contribution that significantly improves onboarding for new contributors. The minor issues identified are cosmetic and don't block merging. The date typo should be fixed, but the PR can be merged as-is if desired.

Impact: 📈 High positive impact - Fills a critical gap in understanding system architecture without reading thousands of lines of code.

Risk: ⚠️ Low - Documentation-only change, no code modifications, no security/performance concerns.

Claude Code Review

Summary

This PR adds comprehensive architecture workflow documentation with visual Mermaid diagrams. The contribution is excellent for new contributors and provides clear, accurate visual representations of how the system components interact. The diagrams correctly capture the Kubernetes-native architecture, authentication patterns, and component interactions.

Issues by Severity

🚫 Blocker Issues

None - This PR is ready to merge.

🔴 Critical Issues

None

🟡 Major Issues

1. Documentation Standards Conflict

Location: Entire PR structure

Issue: CLAUDE.md Documentation Standards (line 992-997) state:

"Default to improving existing documentation" rather than creating new files. When adding or updating documentation:

  • Prefer inline updates: Improve existing markdown files or code comments
  • Colocate new docs: When feasible, documentation should live in the subdirectory that has the relevant code
  • Avoid top-level proliferation: Only create top-level docs for cross-cutting concerns

Why this matters: The project has established patterns to prevent documentation sprawl. This PR creates a new top-level doc when the content could potentially be integrated into existing architecture documentation.

Counter-argument (why this might be acceptable):

  • This IS a cross-cutting concern (covers all components)
  • No single component directory would be appropriate
  • The visual diagrams provide unique value not present in existing docs
  • The docs/ directory is the standard location for cross-cutting architecture docs
  • Already referenced from CLAUDE.md and README.md, making it discoverable

Recommendation: Accept as-is, but note for future contributions that the project prefers updating existing docs first.

🔵 Minor Issues

1. Inconsistent Diagram Formatting

Location: Multiple sequence diagrams

Issue: Some diagrams use proper Mermaid note syntax, others use inconsistent spacing/formatting.

Example:

Line 101: "Note over Runner, Backend: Initialization" (good)
Line 137: "Note over FE, BE: Session Creation" (good)

Recommendation: Formatting is consistent enough. No action required.

2. Missing Multi-Repo Support in Diagrams

Location: Diagram 1 (High-Level System Architecture)

Issue: CLAUDE.md (lines 255-261) documents multi-repo support as a key feature:

AgenticSessions support operating on multiple repositories simultaneously:

  • Each repo has required input (URL, branch) and optional output (fork/target) configuration
  • mainRepoIndex specifies which repo is the Claude working directory

Impact: Diagrams don't show this capability, which might confuse users trying to use multi-repo sessions.

Recommendation: Consider adding a note or optional box showing "Multi-Repo Support (mainRepoIndex)" in future iterations. Not blocking.

3. Terminology: "Claude Code CLI" vs "Claude Code SDK"

Location: Lines 27, 47, 253

Issue: Documentation uses "Claude Code CLI" in diagrams but actual runner uses "Claude Code SDK" (Python library). CLAUDE.md line 296 states:

Claude Code SDK integration (claude-code-sdk>=0.0.23)

Why this matters: May confuse developers looking at runner code vs. diagrams.

Recommendation: Update diagram terminology from "Claude Code CLI" to "Claude Code SDK" for accuracy. Line 253 correctly uses "Claude Code SDK" but lines 27 and 47 use "ClaudeCLI" which is imprecise.

Positive Highlights

Architecture Accuracy ✅

Diagram 2 (Backend Internal Interactions) correctly captures the critical security pattern documented in .claude/patterns/k8s-client-usage.md:

  • User-Scoped Client for Read/List operations
  • Backend SA Client only for Write/Mint after RBAC validation
  • Clear separation of concerns

This is EXACTLY the pattern the codebase enforces. Excellent understanding.

Security Pattern Documentation ✅

Lines 84-88 perfectly describe the authentication flow:

All user operations validated with user bearer tokens; backend service account used only for privileged operations after authorization checks.

This aligns with .claude/context/security-standards.md critical rules. Well done.

Component Communication Clarity ✅

Diagram 3 (Backend <-> Runner Interaction) accurately shows:

  • WebSocket initialization
  • Bidirectional streaming (logs, status, tool executions)
  • Git operations flow
  • Proper error handling with final exit codes

This matches the actual implementation in components/runners/claude-code-runner/.

Lifecycle Management Accuracy ✅

Diagram 5 (Operator <-> Runner Lifecycle) correctly captures:

  • CR watch pattern with reconnection
  • Job creation with environment injection
  • Goroutine monitoring (components/operator/internal/handlers/sessions.go:477)
  • Status update flow using UpdateStatus subresource

This demonstrates deep understanding of the operator pattern.

Formatting & Readability ✅

  • Clean Mermaid syntax throughout
  • Consistent styling with color coding
  • Clear section separators
  • Good use of workflow explanations after each diagram
  • Proper integration into MkDocs navigation

Recommendations

High Priority (Should Address Before Merge)

  1. Terminology Consistency: Update lines 27 and 47 to use "Claude Code SDK" instead of "Claude Code CLI" or "ClaudeCLI" to match line 253 and the actual implementation.

Medium Priority (Can Address in Follow-up)

  1. Add Multi-Repo Note: Consider adding a small note or annotation in Diagram 1 mentioning multi-repo support for completeness.

  2. Add RFE Workflow Diagram: CLAUDE.md documents RFE workflows as a primary CRD (lines 253-254). A diagram showing the 7-step agent council process would be valuable for users.

Low Priority (Nice-to-Have)

  1. Add Interactive Mode Distinction: CLAUDE.md (lines 263-266) documents batch vs. interactive mode. A small annotation in the diagrams could clarify which flows apply to each mode.

  2. Add PVC Proxy Detail: Line 172 mentions PVC but doesn't explain the PVC proxy pattern for workspace synchronization (CLAUDE.md line 298). Consider expanding this in a future iteration.

Final Verdict

APPROVED ✅

This is an excellent contribution that provides significant value to new contributors. The diagrams are technically accurate, well-formatted, and correctly integrated into the documentation structure.

The only required change is the terminology fix (CLI → SDK) for consistency. Everything else is optional enhancement for future PRs.

Why this PR succeeds:

  • Addresses real onboarding pain point ("I was struggling to completely understand how different components interact")
  • Provides visual learning aids (6 comprehensive diagrams)
  • Accurate representation of actual implementation patterns
  • Properly integrated into existing documentation infrastructure
  • Follows established architectural patterns

Impact:

  • Reduces onboarding time for new contributors
  • Serves as visual reference for architecture discussions
  • Complements existing text-based documentation
  • Demonstrates contributor's thorough understanding of the system

Thank you for this valuable contribution! 🎉

Claude Code Review

Summary

This PR adds comprehensive architecture workflow documentation with Mermaid diagrams to help new contributors understand component interactions. The documentation is well-structured, visually clear, and technically accurate. It effectively bridges the gap between high-level architecture concepts and implementation details.

Overall Assessment:APPROVED - High-quality documentation contribution with minor suggestions for enhancement.


Issues by Severity

🚫 Blocker Issues

None - This PR is ready to merge.


🔴 Critical Issues

None - All critical aspects are properly addressed.


🟡 Major Issues

1. Missing Security Context in Diagrams

Location: Section 5 (Operator <-> Runner Lifecycle)

Issue: The diagram shows environment variable injection but doesn't explicitly call out the security-critical aspects mentioned in CLAUDE.md:

  • SecurityContext settings (AllowPrivilegeEscalation: false, Capabilities.Drop: ALL)
  • OwnerReferences for cleanup
  • Token minting process

Suggestion: Add a note in the "Lifecycle Details" section:

-   **Security:** Job pods are created with restrictive SecurityContext (no privilege escalation, all capabilities dropped), and OwnerReferences ensure automatic cleanup when the session is deleted.

Impact: Medium - Security patterns are documented elsewhere, but diagrams for new contributors should hint at these critical concerns.


2. WebSocket Path Inconsistency

Location: Section 3 (Backend <-> Runner Interaction), Line 103

Issue: The diagram shows /sessions/:id/ws but the actual implementation needs verification. Based on the backend structure, WebSocket endpoints are typically under /ws/... namespace.

Current:

Runner->>Backend: WebSocket Connect /sessions/:id/ws

Verify: Check if the actual path is /ws/sessions/:id or similar (based on websocket/handlers.go routing).

Impact: Medium - Could confuse developers trying to trace actual WebSocket connections.


🔵 Minor Issues

1. Missing Multi-Repo Support Context

Location: Section 1 (High-Level System Architecture)

Issue: The diagrams don't mention the platform's multi-repo support capability, which is a key feature mentioned in CLAUDE.md.

Suggestion: Add a note under "Workflow Explanation":

6. **Multi-Repo:** Sessions can operate on multiple repositories simultaneously, with `mainRepoIndex` specifying the working directory.

Impact: Low - Feature is documented elsewhere, but architectural overview should mention it.


2. Interactive vs Batch Mode Not Visualized

Location: All sections

Issue: The documentation doesn't distinguish between interactive (long-running chat) and batch (single prompt) execution modes.

Suggestion: Add a brief note in Section 6 (Runner Internal Execution Flow):

**Execution Modes:**
- **Batch Mode** (default): Single prompt execution with timeout
- **Interactive Mode**: Long-running chat sessions using inbox/outbox files for user interaction

Impact: Low - Helps clarify different session types.


3. Reference to wrapper.py Without Context

Location: Section 3 (Details), Line 123

Issue: Mentions wrapper.py but doesn't explain what it is or where it lives.

Suggestion: Add clarification:

-   **Communication:** The Runner container executes a wrapper script (`wrapper.py` in `components/runners/claude-code-runner/`) around the Claude Code SDK to establish a persistent WebSocket connection.

Impact: Low - Minor clarity improvement.


4. Documentation Standards Compliance

Location: File placement

Issue: Per CLAUDE.md documentation standards: "Prefer inline updates" and "Colocate new docs". However, this cross-cutting architectural documentation correctly belongs in docs/ (not component-specific).

Status:Correct placement - This is appropriately placed in docs/ as it's a cross-cutting concern.


Positive Highlights

✨ Excellent Work

  1. Visual Clarity - The Mermaid diagrams are clean, well-organized, and use consistent styling. Color coding helps distinguish components.

  2. Progressive Disclosure - The documentation builds understanding progressively:

    • High-level system architecture
    • Component internals
    • Interaction patterns
    • Execution details
  3. Technical Accuracy - The diagrams correctly represent:

    • User-scoped vs Service Account client usage (Section 2)
    • RBAC authorization flow
    • CR watch patterns
    • Job lifecycle management
  4. Security Awareness - Section 2 explicitly calls out the critical security pattern:

    "All user operations validated with user bearer tokens; backend service account used only for privileged operations after authorization checks."

    This aligns perfectly with the security standards documented in .claude/context/security-standards.md.

  5. Practical Value - The "Key Internal Flows", "Key Interactions", and "Lifecycle Details" sections provide actionable context for developers.

  6. Integration with Existing Docs - Proper links added to CLAUDE.md and README.md for discoverability.

  7. MkDocs Integration - Added to mkdocs.yml navigation, making it part of the official documentation site.


Recommendations

Priority 1 (Before Merge - Optional)

  1. Verify WebSocket Path - Confirm the exact WebSocket endpoint path and update Section 3 if needed.
  2. Add Security Note - Enhance Section 5 with security context information.

Priority 2 (Future Enhancements)

  1. Add Failure Scenarios - Consider adding a diagram showing error handling and retry logic.
  2. RFE Workflow Visualization - The platform has a sophisticated RFE workflow (7-step agent council). A separate diagram for this would be valuable.
  3. Authentication Flow Detail - A dedicated sequence diagram for OAuth proxy authentication flow would complement this documentation.

Priority 3 (Nice-to-Have)

  1. Interactive Mode Detail - Add a separate sequence diagram showing interactive session message flow (inbox/outbox files).
  2. PVC Proxy Detail - Explain workspace synchronization via PVC proxy in more detail.

🔵 Minor Issues

1. Inconsistent Terminology - "RunnerShell" vs Actual Implementation

  • Location: docs/architecture-workflows.md:26
  • Issue: The diagram shows RunnerShell[Runner Shell] as a separate component, but based on the codebase, the runner uses wrapper.py which wraps the Claude Code SDK directly.
  • Impact: Minor confusion for contributors trying to map diagrams to actual code
  • Recommendation: Consider updating to show Wrapper[wrapper.py] instead of RunnerShell for accuracy, or add a note explaining the conceptual abstraction.

2. Missing Reference to Multi-Repo Support
