Agent Skills: Spec Completion Review Mode

Spec Completion Review Mode

Workflow is backend-split. Read workflow-common.md for Phase 0 (backend detection + philosophy), then read ONLY the file matching your active backend:

• BACKEND=codex → workflow-codex.md
• BACKEND=copilot → workflow-copilot.md
• BACKEND=cursor → workflow-cursor.md
• BACKEND=rp → workflow-rp.md

Do not load the others — only the active backend's file is needed.

Verify that the combined implementation of all tasks in a spec satisfies the spec requirements. This is NOT a code quality review (that's impl-review's job) — this confirms spec compliance only.

Role: Spec Completion Review Coordinator (NOT the reviewer) Backends (branch on the Phase 0 RP_ELIGIBLE probe):

• When RP_ELIGIBLE=1: RepoPrompt (rp), Codex CLI (codex), GitHub Copilot CLI (copilot), or Cursor CLI (cursor)
• When RP_ELIGIBLE=0: Codex CLI (codex), GitHub Copilot CLI (copilot), or Cursor CLI (cursor) — rp is macOS-only; never list it in guidance you surface (--review=rp stays accepted)

Preamble — execute Phase 0 exactly once

The executable Phase 0 lives in workflow-common.md §"Phase 0: Backend Detection" — Read it and execute it ONCE, before any other bash in this skill. It defines $FLOWCTL (bundled — NOT installed globally; which flowctl fails, expected), probes RP_ELIGIBLE, resolves $BACKEND via the single flowctl review-backend call, and handles the ASK / none cases. Never invoke flowctl review-backend a second time in the same run.

Exception: a --review=<backend> argument (see Backend Selection below) wins — when present, set BACKEND from the flag and skip Phase 0's review-backend call + ASK handling (still run its $FLOWCTL / RP_ELIGIBLE setup lines).

When RP_ELIGIBLE=0 (not macOS, no rp-cli), never steer the user toward rp: every backend summary, recommendation, or override hint you surface presents only the runnable configured backends codex, copilot, cursor (plus none). Suppression is not a ban: an explicit --review=rp, FLOW_REVIEW_BACKEND=rp, or review.backend=rp still resolves to rp and errors at runtime via require_rp_cli() as today.

Backend Selection

Priority (first match wins):

1. --review=rp|codex|copilot|cursor|none argument
2. FLOW_REVIEW_BACKEND env var — bare backend (rp, codex, copilot, cursor, none) OR spec form (codex:gpt-5.4:xhigh, copilot:claude-opus-4.5, cursor:gpt-5.5-high)
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=cursor or --review cursor → use cursor
• --review=none or --review none → skip review

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

Otherwise: Phase 0 resolves it

No --review flag → $BACKEND comes from workflow-common.md Phase 0 (executed once per the Preamble): the single flowctl review-backend "$SPEC_ID" call with ASK handling included. Do not re-resolve here.

Backend at a glance

When RP_ELIGIBLE=0, omit the rp line below from any guidance you surface (explicit --review=rp still honored):

• 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.
• cursor — Cursor CLI (cursor-agent, cross-platform); reaches gpt-5.5-high (1M-ctx default), the gpt-5.3-codex family, composer-2.5, and claude-opus-4-8-thinking-high via a Cursor subscription. FLOW_CURSOR_MODEL env var, or --spec cursor:gpt-5.5-high. Cursor folds reasoning effort into the model name — no effort field.

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, cursor:gpt-5.5-high (cursor takes model only — no :effort). Per-spec default_review (set via flowctl spec set-backend) overrides env.

Critical Rules

For rp backend:

1. DO NOT REVIEW CODE 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 completion-review exclusively
2. Pass --receipt for session continuity on re-reviews
3. Parse verdict from command output

For copilot backend:

1. Use $FLOWCTL copilot completion-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 cursor backend:

1. Use $FLOWCTL cursor completion-review exclusively
2. Pass --receipt for session continuity on re-reviews (session only resumes when prior receipt has mode == "cursor")
3. Model resolved via (first match wins): --spec cursor:<model> flag, per-spec default_review, FLOW_REVIEW_BACKEND spec, FLOW_CURSOR_MODEL env var, registry default (gpt-5.5-high). No effort — Cursor bakes effort into the model name; cursor:<model>:<effort> is rejected
4. Parse verdict from command output

For all backends:

• If REVIEW_RECEIPT_PATH set: 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: <spec-id> [--review=rp|codex|copilot|cursor|none]

• Spec ID - Required, e.g. fn-1 or fn-22-53k
• --review - Optional backend override

Workflow

REPO_ROOT="$(git rev-parse --show-toplevel 2>/dev/null || pwd)"

Step 0: Parse Arguments

Parse $ARGUMENTS for:

• First positional arg matching fn-* → SPEC_ID
• --review=<backend> → backend override
• Remaining args → focus areas

Step 1: Load Backend Workflow

1. $BACKEND was already resolved by workflow-common.md Phase 0 (Preamble) — do NOT re-run it.
2. Read only the file for that backend:

| $BACKEND | File to read | |------------|--------------| | codex | workflow-codex.md | | copilot | workflow-copilot.md | | cursor | workflow-cursor.md | | rp | workflow-rp.md |

Do not read the other backend files. Each is self-contained for its backend; loading the others wastes context.

Step 2: Execute the backend workflow

Follow the phases in the per-backend file end-to-end. Each file owns its own Identify → Execute → Verdict → Receipt steps (and, for RP, the full Phase 1-4 setup-review / chat-send / receipt build).

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.

MAX ITERATIONS (backend-agnostic — applies to ALL backends: rp, codex, copilot, cursor): keep an iteration counter in agent context, starting at 0. Each fix+re-review cycle increments it. When the counter reaches ${MAX_REVIEW_ITERATIONS:-4} (default 4; env-overridable, configurable in Ralph's config.env) and the verdict is still NEEDS_WORK, BREAK the loop and escalate: surface the surviving gaps to the caller and stop (in Ralph mode output <promise>RETRY</promise> so the next iteration starts fresh). Never loop unbounded. The per-backend workflow files defer to this cap.

If verdict is NEEDS_WORK, loop internally until SHIP or the iteration cap:

1. Parse issues from reviewer feedback (missing requirements, incomplete implementations)
2. Fix code and run tests/lints
3. Commit fixes (mandatory before re-review; RP backend uses the snapshot-scoped staging in workflow-rp.md — never blanket-stage with git add --all)
4. Re-review:
   • Codex: Re-run flowctl codex completion-review (receipt enables context)
   • Copilot: Re-run flowctl copilot completion-review (receipt enables context; must be mode == "copilot" to resume)
   • Cursor: Re-run flowctl cursor completion-review (receipt enables context; must be mode == "cursor" to resume)
   • RP: $FLOWCTL rp chat-send --window "$W" --tab "$T" --message-file <literal re-review path from workflow-rp.md's fix loop> (NO --new-chat; stdout redirected to the same literal response file, Read once)
5. Repeat until <verdict>SHIP</verdict> — or the MAX ITERATIONS cap above breaks the loop (escalate with surviving gaps)

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

Step 3: Record the verdict (MANDATORY — every backend, every terminal outcome)

The moment the fix loop terminates, write the outcome back so the rest of the pipeline sees it — exactly as /flow-next:plan-review writes set-plan-review-status. Without this, a standalone completion review leaves completion_review_status: unknown, which keeps flowctl ready --require-completion-review demanding a review (pilot's gate), feeds make-pr's Open-items / draft heuristic stale state, and blocks tracker-sync's terminal verified rung.

# Final verdict resolved to SHIP → ship; NEEDS_WORK at the iteration cap → needs_work.
$FLOWCTL spec set-completion-review-status "$SPEC_ID" --status ship --json        # on SHIP
$FLOWCTL spec set-completion-review-status "$SPEC_ID" --status needs_work --json  # on NEEDS_WORK at cap

Write it on BOTH terminal paths (SHIP and capped-NEEDS_WORK). This is the same write /flow-next:work performs when it runs completion-review inline; a standalone invocation must not skip it.
