flow-next-plan-review

name: flow-next-plan-review description: Carmack-level plan review via RepoPrompt or Codex. Use when reviewing Flow specs or design docs. Triggers on /flow-next:plan-review. user-invocable: false

Plan Review Mode

Read workflow.md for detailed phases and anti-patterns.

Conduct a John Carmack-level review of spec plans.

Role: Code Review Coordinator (NOT the reviewer) Backends: RepoPrompt (rp), Codex CLI (codex), or GitHub Copilot CLI (copilot)

Preamble

CRITICAL: flowctl is BUNDLED — NOT installed globally. which flowctl will fail (expected). Define once; subsequent blocks (here and in workflow.md) use $FLOWCTL:

FLOWCTL="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/flowctl"
[ -x "$FLOWCTL" ] || FLOWCTL=".flow/bin/flowctl"

Backend Selection

Priority (first match wins):

1. --review=rp|codex|copilot|export|none argument
2. FLOW_REVIEW_BACKEND env var — bare backend (rp, codex, copilot, none) OR spec form (codex:gpt-5.4:xhigh, copilot:claude-opus-4.5)
3. .flow/config.json → review.backend (same bare / spec forms)
4. Error - no auto-detection

Parse from arguments first

Check $ARGUMENTS for:

• --review=rp or --review rp → use rp
• --review=codex or --review codex → use codex
• --review=copilot or --review copilot → use copilot
• --review=export or --review export → use export
• --review=none or --review none → skip review

If found, use that backend and skip all other detection.

Otherwise read from config

# Priority: --review flag > env > config
BACKEND=$($FLOWCTL review-backend)

if [[ "$BACKEND" == "ASK" ]]; then
  echo "Error: No review backend configured."
  echo "Run /flow-next:setup to configure, or pass --review=rp|codex|copilot|none"
  exit 1
fi

echo "Review backend: $BACKEND (override: --review=rp|codex|copilot|none)"

Backend at a glance

• rp — RepoPrompt (macOS GUI); builder auto-selects context. Primary backend.
• codex — Codex CLI (cross-platform); uses OpenAI models (default gpt-5.5). FLOW_CODEX_MODEL / FLOW_CODEX_EFFORT env vars, or --spec codex:gpt-5.4:xhigh.
• copilot — GitHub Copilot CLI (cross-platform); supports Claude Opus/Sonnet/Haiku 4.5 and GPT-5.2 families via a Copilot subscription. FLOW_COPILOT_MODEL / FLOW_COPILOT_EFFORT env vars, or --spec copilot:claude-opus-4.5:xhigh.

Spec grammar: backend[:model[:effort]] — FLOW_REVIEW_BACKEND and .flow/config.json review.backend both accept this. Examples: codex, codex:gpt-5.2, copilot:claude-opus-4.5:xhigh. Per-spec default_review (set via flowctl spec set-backend) overrides env.

Critical Rules

For rp backend:

1. DO NOT REVIEW THE PLAN YOURSELF - you coordinate, RepoPrompt reviews
2. MUST WAIT for actual RP response - never simulate/skip the review
3. MUST use setup-review - handles window selection + builder atomically
4. DO NOT add --json flag to chat-send - it suppresses the review response
5. Re-reviews MUST stay in SAME chat - omit --new-chat after first review

For codex backend:

1. Use $FLOWCTL codex plan-review exclusively
2. Pass --receipt for session continuity on re-reviews
3. Parse verdict from command output

For copilot backend:

1. Use $FLOWCTL copilot plan-review exclusively
2. Pass --receipt for session continuity on re-reviews (session only resumes when prior receipt has mode == "copilot")
3. Model + effort resolved via (first match wins): --spec backend:model:effort flag, per-spec default_review, FLOW_REVIEW_BACKEND spec, FLOW_COPILOT_MODEL / FLOW_COPILOT_EFFORT env vars, registry defaults
4. Parse verdict from command output

For all backends:

• If REVIEW_RECEIPT_PATH set: write receipt after review (any verdict)
• Any failure → output <promise>RETRY</promise> and stop

FORBIDDEN:

• Self-declaring SHIP without actual backend verdict
• Mixing backends mid-review (stick to one)
• Skipping review when backend is "none" without user consent

Step 0: Detect Backend

Run backend detection from SKILL.md above. Then branch:

Codex Backend

SPEC_ID="${1:-}"
RECEIPT_PATH="${REVIEW_RECEIPT_PATH:-/tmp/plan-review-receipt.json}"

# Save checkpoint before review (recovery point if context compacts)
$FLOWCTL checkpoint save --spec "$SPEC_ID" --json

# --files: comma-separated CODE files for reviewer context
# Spec/task specs are auto-included; pass files the plan will CREATE or MODIFY
# How to identify: read the spec, find files mentioned or directories affected
# Example: spec touches auth → pass existing auth files for context
#
# Dynamic approach (if spec mentions specific paths):
#   CODE_FILES=$(grep -oE 'src/[^ ]+\.(ts|py|js)' .flow/specs/${SPEC_ID}.md | sort -u | paste -sd,)
# Or list key files manually:
CODE_FILES="src/main.py,src/config.py"

$FLOWCTL codex plan-review "$SPEC_ID" --files "$CODE_FILES" --receipt "$RECEIPT_PATH"
# Output includes VERDICT=SHIP|NEEDS_WORK|MAJOR_RETHINK

On NEEDS_WORK: fix plan via $FLOWCTL spec set-plan AND sync affected task specs via $FLOWCTL task set-spec, then re-run (receipt enables session continuity).

Note: codex plan-review automatically includes task specs in the review prompt.

Copilot Backend

SPEC_ID="${1:-}"
RECEIPT_PATH="${REVIEW_RECEIPT_PATH:-/tmp/plan-review-receipt.json}"

# Save checkpoint before review (recovery point if context compacts)
$FLOWCTL checkpoint save --spec "$SPEC_ID" --json

# --files: comma-separated CODE files for reviewer context (same shape as codex)
# Spec/task specs are auto-included; pass files the plan will CREATE or MODIFY
CODE_FILES="src/main.py,src/config.py"

# Override model + effort (pick one):
#   --spec copilot:claude-opus-4.5:xhigh   (preferred)
#   FLOW_REVIEW_BACKEND=copilot:claude-opus-4.5:xhigh
#   FLOW_COPILOT_MODEL=gpt-5.2 FLOW_COPILOT_EFFORT=high

$FLOWCTL copilot plan-review "$SPEC_ID" --files "$CODE_FILES" --receipt "$RECEIPT_PATH"
# Output includes VERDICT=SHIP|NEEDS_WORK|MAJOR_RETHINK

On NEEDS_WORK: fix plan via $FLOWCTL spec set-plan AND sync affected task specs via $FLOWCTL task set-spec, then re-run. Session resume only when prior receipt has mode == "copilot".

Note: copilot plan-review automatically includes task specs in the review prompt (same as codex).

RepoPrompt Backend

⚠️ STOP: You MUST read and execute workflow.md now.

Go to the "RepoPrompt Backend Workflow" section in workflow.md and execute those steps. Do not proceed here until workflow.md phases are complete.

The workflow covers:

1. Get plan content and save checkpoint
2. Atomic setup (setup-review) → sets $W and $T
3. Augment selection (spec + task specs)
4. Send review and parse verdict

Return here only after workflow.md execution is complete.

Fix Loop (INTERNAL - do not exit to Ralph)

CRITICAL: Do NOT ask user for confirmation. Automatically fix ALL valid issues and re-review — our goal is production-grade world-class software and architecture. Never use AskUserQuestion in this loop.

If verdict is NEEDS_WORK, loop internally until SHIP:

1. Parse issues from reviewer feedback
2. Fix spec (stdin preferred, temp file if content has single quotes):

   # Preferred: stdin heredoc
   $FLOWCTL spec set-plan <SPEC_ID> --file - --json <<'EOF'
   <updated spec content>
   EOF
   
   # Or temp file
   $FLOWCTL spec set-plan <SPEC_ID> --file /tmp/updated-plan.md --json
   

3. Sync affected task specs - If spec changes affect task specs, update them:

   $FLOWCTL task set-spec <TASK_ID> --file - --json <<'EOF'
   <updated task spec content>
   EOF
   

   Task specs need updating when spec changes affect:
   • State/enum values referenced in tasks
   • Acceptance criteria that tasks implement
   • Approach/design decisions tasks depend on
   • Lock/retry/error handling semantics
   • API signatures or type definitions
4. Re-review:
   • Codex: Re-run flowctl codex plan-review (receipt enables context)
   • Copilot: Re-run flowctl copilot plan-review (receipt enables context; must be mode == "copilot" to resume)
   • RP: $FLOWCTL rp chat-send --window "$W" --tab "$T" --message-file /tmp/re-review.md (NO --new-chat)
5. Repeat until <verdict>SHIP</verdict>

Recovery: If context compaction occurred during review, restore from checkpoint:

$FLOWCTL checkpoint restore --spec <SPEC_ID> --json

CRITICAL: For RP, re-reviews must stay in the SAME chat so reviewer has context. Only use --new-chat on the FIRST review.
