Tier 1.1-1.2: Artifact Packaging + MCP Remote Protocol

[kanfil]

Summary

Epic issue for Tier 1 Async Task Context Delivery - Part 1

Sub-items

Tier 1.1 - Artifact Context Packaging

• ❌ Spec Context Bundling: Create scripts/bash/package-spec-context.sh to bundle spec.md + plan.md + research.md + context.md as unified delivery unit
• ❌ Payload Strategy Selection: Support embedded payload for specs < 150K tokens; URL references for larger repos
• ❌ Git Metadata Inclusion: Include repo URL, branch, commit SHA in package for remote context
• ❌ PowerShell Equivalent: Implement scripts/powershell/Package-SpecContext.ps1 with cross-platform parity

Tier 1.2 - Remote MCP Task Submission Protocol

• ❌ Standard MCP Tools: Define submit_async_task, check_task_status, get_task_result tools in MCP schema
• ❌ Agent Type Support: Implement endpoints for async-copilot, async-codex, jules, and custom agents
• ❌ Endpoint Registration: Extend .mcp.json configuration to register remote agent endpoints per type
• ❌ Model Parameter Passthrough: Allow --model parameter to flow through to remote agent execution
• ❌ Agent Selection Logic: Route tasks to appropriate agent based on /tasks metadata (ASYNC tag + agent type)

Priority

Critical - Unblocks full async workflow
