🔧 Semantic Function Clustering Analysis

Repository analyzed: githubnext/gh-aw
Analysis date: 2025-11-12
Total non-test Go files analyzed: 206
Total functions cataloged: 1,269
Total lines of code: ~186,000

Executive Summary

This analysis examined the codebase structure to identify opportunities for improved code organization through semantic function clustering. The repository follows strong naming conventions and feature-based organization patterns, particularly in the pkg/cli and pkg/workflow packages.

Key findings:

  • ✅ Strong file organization with clear naming patterns (*_command.go, mcp_*, create_*, *_validation.go)
  • ⚠️ 5 high-priority outliers identified (functions in wrong files)
  • ⚠️ 3 significant duplicate patterns detected (similar logic across files)
  • ⚠️ Validation logic concentration issue in pkg/workflow/validation.go
  • ✅ Minimal problematic duplication overall (most duplication is acceptable engine-specific customization)
Detailed Analysis Report

Package Organization Overview

pkg/cli (69 files)

Organization patterns:

  • Command pattern (*_command.go): 10 files with New*Command() entry points
  • Feature prefixes (mcp_*, logs_*): 16 MCP files, 5 logs files
  • Domain files: GitHub (github.go, git.go, repo.go), Actions (actions.go, workflows.go)
  • Core infrastructure: commands.go, init.go, resolver.go

Strengths:

  • Clear command organization with consistent structure
  • Feature clustering (MCP files together, logs files together)
  • Well-defined entry points for CLI commands

Issues identified:

  • logs.go is overloaded (35+ symbols, mixed concerns)
  • Template strings stored in commands.go instead of dedicated file
  • GitHub API operations scattered across multiple files

pkg/workflow (123 files)

Organization patterns:

  • Operation-based (create_*.go): 6 creation files with consistent structure
  • Validation suite (*_validation.go): 13 validation files
  • Engine architecture (*_engine.go): 10 engine-related files
  • Compiler core (compiler*.go): 3 compiler files
  • Package managers: 6 package manager files with paired validation
  • Prompt generation (*_prompt.go): 6 specialized prompt files
  • MCP configuration: 3 MCP-related files

Strengths:

  • Excellent naming consistency
  • Clear separation of concerns (creation, validation, compilation)
  • Engine infrastructure properly separated from implementations
  • Package managers follow consistent pairing pattern

Issues identified:

  • validation.go is catch-all with 33+ functions (should be split)
  • safe_outputs_env_test_helpers.go misnaming (not a test file)
  • config.go is empty placeholder (4 lines)
  • frontmatter_extraction.go very large (24 methods, could be split)

Other packages (5 files)

  • pkg/console: 4 files (console, render, format, spinner) - well organized
  • pkg/constants: 1 file with all constants - appropriate
  • pkg/logger: 1 file - simple logger implementation
  • pkg/parser: 6 files (frontmatter, github, mcp, schema, yaml_error, json_path_locator) - well structured
  • pkg/timeutil: 1 file - utility functions

Function Clustering Results

Cluster 1: Creation Functions (CRUD Operations)

Pattern: create_* functions for GitHub operations
Files: 6 files in pkg/workflow/

create_issue.go              → CreateIssueConfig, parseCreateIssueConfig, buildCreateIssueJob
create_pull_request.go       → CreatePullRequestConfig, parse*, build*
create_discussion.go         → CreateDiscussionConfig, parse*, build*
create_agent_task.go         → CreateAgentTaskConfig, parse*, build*
create_pr_review_comment.go  → CreatePRReviewCommentConfig, parse*, build*
create_code_scanning_alert.go → CreateCodeScanningAlertConfig, parse*, build*

Assessment:Well-organized - Each operation has its own file with consistent structure

Cluster 2: Validation Functions

Pattern: validate* and check* functions
Distribution: Across 13+ files

Primary locations:

  • pkg/workflow/validation.go (33+ functions) ⚠️ OVERLOADED
  • Specialized validators (properly split):
    • bundler_validation.go (1 function)
    • docker_validation.go (1 function)
    • npm_validation.go (1 function)
    • pip_validation.go (4 functions)
    • template_validation.go (1 function)
    • expression_validation.go (2 functions)

Also in CLI:

  • pkg/cli/mcp_validation.go (2 functions)
  • pkg/cli/run_command.go (validateRemoteWorkflow)
  • pkg/cli/add_command.go (workflow validation)

Issue: validation.go contains unrelated validations:

  • Expression sizes

  • Runtime packages
  • GitHub Actions schema
  • Secret references
  • Repository features (6 helper functions)
  • HTTP transport support
  • Max turns support
  • Web search support
  • Agent file validation

Assessment:Well-organized - Clear separation between infrastructure and implementations

Cluster 4: Package Extraction Functions

Pattern: extract*FromCommands functions
Significant similarity detected ⚠️

npm.go:

func extractNpxFromCommands(commands string) []string {
    var packages []string
    lines := strings.Split(commands, "\n")
    for _, line := range lines {
        words := strings.Fields(line)
        for i, word := range words {
            if word == "npx" && i+1 < len(words) {
                // Skip flags and find first package
                for j := i + 1; j < len(words); j++ {
                    pkg := words[j]
                    pkg = strings.TrimRight(pkg, "&|;")
                    if !strings.HasPrefix(pkg, "-") {
                        packages = append(packages, pkg)
                        break
                    }
                }
            }
        }
    }
    return packages
}

pip.go:

func extractPipFromCommands(commands string) []string {
    var packages []string
    lines := strings.Split(commands, "\n")
    for _, line := range lines {
        words := strings.Fields(line)
        for i, word := range words {
            if (word == "pip" || word == "pip3") && i+1 < len(words) {
                for j := i + 1; j < len(words); j++ {
                    if words[j] == "install" {
                        // Same flag-skipping logic...
                    }
                }
            }
        }
    }
    return packages
}

Similarity: ~75% - Same structure, flag-skipping logic, and string processing

Also similar: extractUvFromCommands, extractGoFromCommands

Identified Issues

1. Outlier Functions (High Priority)

Issue #1: Setup Functions in Wrong File

**(redacted) pkg/cli/add_command.go
Problem: Contains multiple setup functions unrelated to adding workflows

Outlier functions:

func ensureCopilotInstructions(...)           // Line 819
func ensureAgenticWorkflowPrompt(...)         // Line 869  
func ensureAgenticWorkflowAgent(...)          // Line 897
func ensureSharedAgenticWorkflowAgent(...)    // Line 902
func ensureSetupAgenticWorkflowsAgent(...)    // Line 907

Recommendation: Move to copilot_setup.go or new agent_setup.go file
Impact: Improved file cohesion, clearer separation of concerns

Issue #2: Git/PR Operations in Command File

**(redacted) pkg/cli/add_command.go
Problem: Contains Git and PR operations that belong elsewhere

Outlier functions:

func checkCleanWorkingDirectory(...)  // Line 912 → Should be in git.go
func createPR(...)                    // Line 934 → Should be in pr_command.go

Recommendation: Move to appropriate domain files
Impact: Better organization, reusability across commands

Issue #3: Compilation Logic in Add Command

**(redacted) pkg/cli/add_command.go
Problem: Contains compilation logic that overlaps with compile_command.go

Outlier functions:

func compileWorkflow(...)              // Should use compile_command.go
func compileWorkflowWithTracking(...)  // Duplicates compilation logic

Recommendation: Refactor to use shared compilation utilities
Impact: Reduced duplication, single source of truth for compilation

Issue #4: GitHub API Operations Scattered

Problem: GitHub API calls spread across multiple files

Locations:

  • pkg/cli/logs.go: fetchJobStatuses(), fetchJobDetails()
  • pkg/cli/github.go: getGitHubHost()
  • pkg/cli/actions.go: convertToGitHubActionsEnv()
  • pkg/cli/workflows.go: fetchGitHubWorkflows()

Recommendation: Consolidate into dedicated GitHub API client or enhance existing github.go
Impact: Centralized API access, easier maintenance, consistent error handling

Issue #5: Test Helpers File Misnaming

**(redacted) pkg/workflow/safe_outputs_env_test_helpers.go
Problem: Named like test file but NOT a test file (doesn't end with _test.go)

Recommendation: Rename to safe_outputs_test_helpers.go or safe_outputs_env_helpers.go
Impact: Correct naming convention, clarity about file purpose

2. Duplicate or Near-Duplicate Functions

Duplicate #1: Package Extraction Pattern (High Priority)

Similarity: ~75% code similarity
Pattern: Command-line package extraction across different package managers

Files affected:

  • pkg/workflow/npm.go: extractNpxFromCommands
  • pkg/workflow/pip.go: extractPipFromCommands, extractUvFromCommands
  • pkg/workflow/dependabot.go: extractGoFromCommands

Common logic:

  1. Split commands by newlines
  2. Split each line into words
  3. Find package manager command
  4. Skip flags (starting with -)
  5. Extract package names
  6. Trim trailing shell operators (&|;)

Code comparison:

// npm.go - extractNpxFromCommands
var packages []string
lines := strings.Split(commands, "\n")
for _, line := range lines {
    words := strings.Fields(line)
    for i, word := range words {
        if word == "npx" && i+1 < len(words) {
            for j := i + 1; j < len(words); j++ {
                pkg := words[j]
                pkg = strings.TrimRight(pkg, "&|;")
                if !strings.HasPrefix(pkg, "-") {
                    packages = append(packages, pkg)
                    break
                }
            }
        }
    }
}

// pip.go - extractPipFromCommands
var packages []string
lines := strings.Split(commands, "\n")
for _, line := range lines {
    words := strings.Fields(line)
    for i, word := range words {
        if (word == "pip" || word == "pip3") && i+1 < len(words) {
            for j := i + 1; j < len(words); j++ {
                if words[j] == "install" {
                    for k := j + 1; k < len(words); k++ {
                        pkg := words[k]
                        pkg = strings.TrimRight(pkg, "&|;")
                        if !strings.HasPrefix(pkg, "-") {
                            packages = append(packages, pkg)
                            break
                        }
                    }
                    break
                }
            }
        }
    }
}

Recommendation:
Create pkg/workflow/package_extraction.go with generic extraction framework:

type PackageExtractor struct {
    CommandNames []string          // e.g., ["pip", "pip3"]
    RequiredSubcommand string      // e.g., "install" (optional)
    TrimSuffixes string           // e.g., "&|;"
}

func (pe *PackageExtractor) ExtractPackages(commands string) []string {
    // Generic implementation
}

// Usage in npm.go:
var npxExtractor = PackageExtractor{
    CommandNames: []string{"npx"},
    TrimSuffixes: "&|;",
}

func extractNpxFromCommands(commands string) []string {
    return npxExtractor.ExtractPackages(commands)
}

Estimated effort: 3-4 hours
Benefits:

  • Reduced code duplication (~150 lines → ~50 lines)
  • Single source of truth for extraction logic
  • Easier to fix bugs and add features
  • Consistent behavior across package managers

Duplicate #2: Secret Extraction Functions

Similarity: ~60% code similarity
Pattern: Extracting secrets from various sources

Files affected:

  • pkg/workflow/mcp-config.go: extractSecretsFromValue, extractSecretsFromHeaders
  • pkg/cli/secrets.go: extractSecretsFromConfig

Common logic:

  • Pattern matching for ${{ secrets.NAME }}
  • Map building for secret names
  • Similar regex/string parsing approaches

Recommendation: Consolidate into pkg/workflow/secret_extraction.go with shared utilities
Estimated effort: 2-3 hours
Benefits: Centralized secret detection logic, easier maintenance

Duplicate #3: Log Parsing Functions

Similarity: ~50-60% similarity
Pattern: Line-by-line log parsing with similar structure

Files affected:

  • pkg/cli/firewall_log.go: parseFirewallLogLine, parseFirewallLog
  • pkg/cli/access_log.go: parseSquidLogLine, parseSquidAccessLog
  • pkg/cli/logs_parsing.go: parseLogFileWithEngine, parseAgentLog

Common patterns:

  • Open file
  • Read line by line
  • Parse line with regex or field splitting
  • Accumulate results
  • Error handling

Recommendation: Consider shared log parsing utilities in pkg/cli/log_parser.go
Estimated effort: 4-5 hours
Benefits: Reduced duplication, consistent error handling, reusable parsing framework

3. Validation Logic Concentration Issue

**(redacted) pkg/workflow/validation.go
Problem: Catch-all file with 33+ unrelated validation functions (450+ lines)

Current contents (mixed concerns):

  • Expression validation (validateExpressionSizes)
  • Container validation (validateContainerImages)
  • Runtime validation (validateRuntimePackages)
  • Schema validation (validateGitHubActionsSchema)
  • Secret validation (validateSecretReferences)
  • Repository features (6 functions: validateRepositoryFeatures, checkRepositoryHasDiscussions*, checkRepositoryHasIssues*)
  • Agent validation (validateAgentFile, validateMaxTurnsSupport, validateWebSearchSupport)
  • HTTP transport validation

Recommendation: Split into focused files:

validation.go (keep only high-level orchestration)
├── repository_features_validation.go (repository feature checking)
├── schema_validation.go (GitHub Actions schema)
├── runtime_validation.go (packages, containers, expressions)
└── agent_validation.go (agent file, feature support)

Estimated effort: 3-4 hours
Benefits:

  • Clearer separation of concerns
  • Easier to find and maintain validation logic
  • Follows existing pattern of specialized validators
  • Better testability

4. Scattered Helper Functions

Issue: Helper functions distributed but could benefit from consolidation

Current distribution:

  • engine_helpers.go: 15 functions ✅ Good
  • config_helpers.go: 4 functions ✅ Good
  • frontmatter_helpers.go: 2 functions ✅ Good
  • prompt_step_helper.go: 1 function ⚠️ Could be consolidated

Recommendation:

  • Consider compiler_helpers.go for internal Compiler helpers currently embedded in compiler.go
  • Potentially consolidate single-function helper files

Priority: Low (current organization is acceptable)

5. Empty Placeholder File

**(redacted) pkg/workflow/config.go
Content: 4 lines (just a comment saying content moved to config_helpers.go)

Recommendation: Remove file or repurpose for actual config types
Estimated effort: 5 minutes
Impact: Cleaner codebase

  • ✅ Consistent file patterns and clear separation of concerns
  • ✅ Well-organized engine architecture
  • ✅ Minimal problematic duplication (most is acceptable customization)
  • ✅ Clear feature clustering (MCP files, logs files, validation files)

Areas for Improvement:

  • ⚠️ validation.go is overloaded with mixed concerns
  • ⚠️ Package extraction logic duplicated across 3-4 files
  • ⚠️ Some functions in wrong files (setup in add_command.go)
  • ⚠️ Minor naming inconsistencies

Recommended Next Steps:

  1. Address Priority 1 issues (high-impact, low-effort)
  2. Implement package extraction framework (high-value refactoring)
  3. Split validation.go into focused modules
  4. Consider Priority 2 improvements based on development velocity

The proposed refactorings maintain the codebase's strong organizational foundation while addressing specific pain points and duplication patterns. All recommendations preserve existing functionality and aim to improve maintainability, testability, and code reuse.
