Read workflow.md for detailed phases and anti-patterns.
Verify that the combined implementation of all epic tasks satisfies the spec requirements. This is NOT a code quality review (that's impl-review's job) — this confirms spec compliance only.
Role: Epic Review Coordinator (NOT the reviewer) Backends: RepoPrompt (rp), Codex CLI (codex), or GitHub Copilot CLI (copilot)
CRITICAL: flowctl is BUNDLED — NOT installed globally. which flowctl will fail (expected). Always use:
FLOWCTL="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/flowctl"
Backend Selection
Priority (first match wins):
--review=rp|codex|copilot|noneargumentFLOW_REVIEW_BACKENDenv var — bare backend (rp,codex,copilot,none) OR spec form (codex:gpt-5.4:xhigh,copilot:claude-opus-4.5).flow/config.json→review.backend(same bare / spec forms)- Error - no auto-detection
Parse from arguments first
Check $ARGUMENTS for:
--review=rpor--review rp→ use rp--review=codexor--review codex→ use codex--review=copilotor--review copilot→ use copilot--review=noneor--review none→ skip review
If found, use that backend and skip all other detection.
Otherwise read from config
BACKEND=$($FLOWCTL review-backend)
if [[ "$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_EFFORTenv 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_EFFORTenv 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-epic default_review (set via flowctl epic set-backend) overrides env.
Critical Rules
For rp backend:
- DO NOT REVIEW CODE YOURSELF - you coordinate, RepoPrompt reviews
- MUST WAIT for actual RP response - never simulate/skip the review
- MUST use
setup-review- handles window selection + builder atomically - DO NOT add --json flag to chat-send - it suppresses the review response
- Re-reviews MUST stay in SAME chat - omit
--new-chatafter first review
For codex backend:
- Use
$FLOWCTL codex completion-reviewexclusively - Pass
--receiptfor session continuity on re-reviews - Parse verdict from command output
For copilot backend:
- Use
$FLOWCTL copilot completion-reviewexclusively - Pass
--receiptfor session continuity on re-reviews (session only resumes when prior receipt hasmode == "copilot") - Model + effort resolved via (first match wins):
--spec backend:model:effortflag, per-epicdefault_review,FLOW_REVIEW_BACKENDspec,FLOW_COPILOT_MODEL/FLOW_COPILOT_EFFORTenv vars, registry defaults - Parse verdict from command output
For all backends:
- If
REVIEW_RECEIPT_PATHset: write receipt after SHIP verdict (RP writes manually after fix loop; codex writes automatically via--receipt) - 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 silently (must inform user and exit cleanly when backend is "none")
Input
Arguments: $ARGUMENTS
Format: <epic-id> [--review=rp|codex|copilot|none]
- Epic ID - Required, e.g.
fn-1orfn-22-53k --review- Optional backend override
Workflow
See workflow.md for full details on each backend.
FLOWCTL="${DROID_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}/scripts/flowctl"
REPO_ROOT="$(git rev-parse --show-toplevel 2>/dev/null || pwd)"
Step 0: Parse Arguments
Parse $ARGUMENTS for:
- First positional arg matching
fn-*→EPIC_ID --review=<backend>→ backend override- Remaining args → focus areas
Step 1: Detect Backend
Run backend detection from SKILL.md above. Then branch:
Codex Backend
RECEIPT_PATH="${REVIEW_RECEIPT_PATH:-/tmp/completion-review-receipt.json}"
$FLOWCTL codex completion-review "$EPIC_ID" --receipt "$RECEIPT_PATH"
# Output includes VERDICT=SHIP|NEEDS_WORK
On NEEDS_WORK: fix code, commit, re-run (receipt enables session continuity).
Copilot Backend
RECEIPT_PATH="${REVIEW_RECEIPT_PATH:-/tmp/completion-review-receipt.json}"
# 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
$FLOWCTL copilot completion-review "$EPIC_ID" --receipt "$RECEIPT_PATH"
# Output includes VERDICT=SHIP|NEEDS_WORK
On NEEDS_WORK: fix code, commit, re-run. Session resume only when prior receipt has mode == "copilot".
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:
- Gather context (epic spec, tasks, changed files)
- Atomic setup (setup-review) → sets
$Wand$T - Augment selection and build review prompt
- 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 complete spec compliance. Never use AskUserQuestion in this loop.
If verdict is NEEDS_WORK, loop internally until SHIP:
- Parse issues from reviewer feedback (missing requirements, incomplete implementations)
- Fix code and run tests/lints
- Commit fixes (mandatory before re-review)
- Re-review:
- Codex: Re-run
flowctl codex completion-review(receipt enables context) - Copilot: Re-run
flowctl copilot completion-review(receipt enables context; must bemode == "copilot"to resume) - RP:
$FLOWCTL rp chat-send --window "$W" --tab "$T" --message-file /tmp/re-review.md(NO--new-chat)
- Codex: Re-run
- Repeat until
<verdict>SHIP</verdict>
CRITICAL: For RP, re-reviews must stay in the SAME chat so reviewer has context. Only use --new-chat on the FIRST review.
