Summary

  • Add research-planner agent for structured feature planning with clarifying questions, options tables, and commit plans
  • Add Phase 3 execution plan (Executor + SSE streaming), split into overview + 4 reviewable parts:
    • 3.1: Builder checkpointer parameter
    • 3.2: RunContext, RunManager, helpers
    • 3.3: Executor core, streaming, resume protocol
    • 3.4: Routes, schemas, app wiring
  • Update research-planner with plan structure guidance (small vs large features) and revision workflow

Key decisions documented in Phase 3 plan

  • Interrupt detection via aget_state().tasks (not __interrupt__ in stream updates)
  • Schema-based edge derivation (not state.next from mid-stream aget_state)
  • Cooperative timeout excluding human pause time
  • Sequential event IDs for SSE reconnection dedup
  • Simplified resume protocol (buffer-based, no two-phase SSE wait)
  • URL scheme: /v1/runs/{id}/... (deliberately supersedes PROPOSAL)

Review process

Plan went through 2 full review cycles (parallel plan-reviewer per part file), catching 3 critical blockers in the interrupt detection mechanism before any code was written.

Test plan

  • No code changes — planning docs and agent config only
  • All plan files under 500 lines (reviewable in one pass)
  • 52 tests specified across 6 test files

Autonomous agent that researches the codebase, asks clarifying questions,
presents architectural options, and writes plan files with commit plans
and detailed todolists.

Add plan structure guidance (small vs large features, folder layout),
line limits (350-400 aim, 500 max), and revision workflow for
parallel plan-reviewer findings.
