Phase gate: PLAN checkpoint. MUST get APPROVE from all reviewers before proceeding to Build.

Inputs

• Plan file path (default: most recent non-.done.md file in ai-workspace/plans/)
• --include <agent>: Force-add an agent to the panel
• --exclude <agent>: Remove an agent (except technical-editor, which cannot be excluded)

Steps

1. Find the plan file:

   ls -t ai-workspace/plans/*.md | grep -v '.done.md' | head -1
   

   If no plan file found → error: "No plan file in ai-workspace/plans/. Write a plan first." If plan file is .done.md → error: "This plan is already finalized."

2. Read the plan and extract:

   • Files to Modify section
   • Full body text
   • Plan scope (count files changed, count body lines)

3. Assemble the review panel — invoke /assemble-panel with scope = plan file. It returns the panel based on file types and keywords in the plan. Pass --include/--exclude as overrides. Log which agents were selected and why.

   Codex/Cursor: read .claude/skills/assemble-panel/SKILL.md directly and apply the scope/keyword maps inline.

   If /assemble-panel is unavailable, fall back to [technical-editor, code-reviewer] with gate=P2, cap=3.

4. Dispatch all selected agents IN PARALLEL using the Agent tool (single message, multiple Agent tool calls). Each agent receives:

   • The plan file content
   • Their specific review mandate
   • Instructions to return: APPROVE / REVISE / DROP with findings tagged P0/P1/P2

5. Collect verdicts and synthesize into a summary table:

   ## Plan Review Summary
   | Agent | Verdict | P0 | P1 | P2 | Key Finding |
   |-------|---------|----|----|-----|-------------|
   

6. Gate logic and review loop — invoke /assemble-panel for panel governance. It provides the policy algebra (gate=P2, cap=3) and handles RETAIN, EXPAND, CONVERGE, and ESCALATE_RECURRING. Do not duplicate those rules here.

   After each round:

   • All APPROVE with no above-gate findings → "Proceed to Build"
   • Above-gate findings remain → fix, then re-review per assemble-panel's RETAIN + EXPAND rules
   • Cap reached with unresolved findings → escalate to human

   If /assemble-panel is unavailable, fall back: keep all reviewers with above-gate findings, exit at round 3 or when all clean.

Panel Bounds

• Minimum: technical-editor alone (1 agent, trivial plans)
• Typical: technical-editor + code-reviewer + architect-reviewer (3)
• Maximum: all agents (rare, large cross-cutting plans)
