msd-core/gsd-core/workflows/review.md

Cross-AI peer review — invoke external AI CLIs to independently review phase plans. Each CLI gets the same prompt (PROJECT.md context, phase plans, requirements) and produces structured feedback. Results are combined into REVIEWS.md for the planner to incorporate via --reviews flag.

This implements adversarial review: different AI models catch different blind spots. A plan that survives review from 2-3 independent AI systems is more robust.

Check which AI CLIs are available on the system:

# jq prerequisite (#2589). The config/model/budget lookups in this workflow no

jq-dependent reviewer lanes. jq is a production prerequisite for the ollama, lm_studio, llama_cpp, opencode, and antigravity lanes only. If detect_clis reports jq:missing, treat those five as undetected — they follow the same "known-but-undetected" path as a missing CLI (info note, ignored; and if they were the only selected reviewers, fail with the actionable message below rather than producing an empty review). Tell the user to install jq:

NOTE: jq is not on PATH — the ollama, lm_studio, llama_cpp, opencode, and
antigravity reviewer lanes are unavailable. Install jq (https://jqlang.org/download/)
or select a lane that does not require it (--gemini, --claude, --codex,
--coderabbit, --qwen, --cursor).

The remaining lanes (gemini, claude, codex, coderabbit, qwen, cursor) do not require jq and must stay selectable on a jq-less host.

Parse flags from $ARGUMENTS:

• --gemini → include Gemini
• --claude → include Claude
• --codex → include Codex
• --coderabbit → include CodeRabbit
• --opencode → include OpenCode
• --qwen → include Qwen Code
• --cursor → include Cursor
• --agy or --antigravity → include Antigravity CLI
• --ollama → include Ollama (local server, OpenAI-compatible)
• --lm-studio → include LM Studio (local server, OpenAI-compatible)
• --llama-cpp → include llama.cpp (local server, OpenAI-compatible)
• --all → include all available (CLIs + running local servers)
• No flags → if review.default_reviewers is set, include only configured reviewers that are detected; otherwise include all available

Reviewer-selection precedence:

1. Individual reviewer flags (--gemini, --codex, etc.)
2. --all
3. review.default_reviewers
4. No key + no flags → all detected reviewers

review.default_reviewers behavior:

• Value must be a non-empty array of slug strings (configured via gsd config-set review.default_reviewers '["gemini","codex"]')
• Unknown slugs warn and are ignored
• Known-but-undetected slugs emit an info note and are ignored
• If all configured reviewers are unavailable, fail with an actionable message

Reviewer instances (#1517, optional): if review.reviewer_instances is configured, instance names in review.default_reviewers run as independent identities. Resolution rules are in gsd-core/references/reviewer-instances.md — load it lazily only when instances are configured. Unconfigured → default path unchanged.

If no CLIs are available:

No external AI CLIs found. Install at least one:
- gemini: https://github.com/google-gemini/gemini-cli
- codex: https://github.com/openai/codex
- claude: https://github.com/anthropics/claude-code
- opencode: https://opencode.ai (leverages GitHub Copilot subscription models)
- qwen: https://github.com/nicepkg/qwen-code (Alibaba Qwen models)
- cursor: https://cursor.com (Cursor IDE agent mode)
- agy: curl -fsSL https://antigravity.google/cli/install.sh | bash (Antigravity CLI — free with Google credentials)

Then run /gsd:review again.

Exit.

Determine which CLI to skip based on the current runtime environment:

# Environment-based runtime detection (priority order)
if [ "$ANTIGRAVITY_AGENT" = "1" ]; then
  # Antigravity is a separate client — all CLIs are external, skip none
  SELF_CLI="none"
elif [ -n "$CURSOR_SESSION_ID" ]; then
  # Running inside Cursor agent — skip cursor for independence
  SELF_CLI="cursor"
elif [ -n "$CLAUDE_CODE_ENTRYPOINT" ]; then
  # Running inside Claude Code CLI — skip claude for independence
  SELF_CLI="claude"
else
  # Other environments (Gemini CLI, Codex CLI, etc.)
  # Fall back to AI self-identification to decide which CLI to skip
  SELF_CLI="auto"
fi

Rules:

• If SELF_CLI="none" → invoke ALL available CLIs (no skip)
• If SELF_CLI="claude" → skip claude, use gemini/codex
• If SELF_CLI="auto" → the executing AI identifies itself and skips its own CLI
• At least one DIFFERENT CLI must be available for the review to proceed.

Collect phase artifacts for the review prompt:

INIT=$(gsd_run query init.phase-op "${PHASE_ARG}")
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi

# #2358: ONE run-scoped temp dir (portable via ${TMPDIR:-/tmp}) so overlapping
# runs never collide or read each other's stale files.
RUN_DIR=$(mktemp -d "${TMPDIR:-/tmp}/gsd-review-XXXXXX")
echo "RUN_DIR=$RUN_DIR"

Read from init: phase_dir, phase_number, padded_phase.

Capture RUN_DIR above (created ONCE) and thread it into every {run_dir} placeholder and $RUN_DIR/${RUN_DIR} reference within a bash block. Do NOT re-run mktemp -d later — every block must resolve to this same directory, or build_prompt's writes and invoke_reviewers' reads split.

Then read:

1. .planning/PROJECT.md (first 80 lines — project context)
2. Phase section from .planning/ROADMAP.md
3. All *-PLAN.md files in the phase directory
4. *-CONTEXT.md if present (user decisions)
5. *-RESEARCH.md if present (domain research)
6. .planning/REQUIREMENTS.md (requirements this phase addresses)

Build a structured review prompt:

# Cross-AI Plan Review Request

You are reviewing implementation plans for a software project phase.
Provide structured feedback on plan quality, completeness, and risks.

## Project Context
{first 80 lines of PROJECT.md}

## Phase {N}: {phase name}
### Roadmap Section
{roadmap phase section}

### Requirements Addressed
{requirements for this phase}

### User Decisions (CONTEXT.md)
{context if present}

### Research Findings
{research if present}

### Plans to Review
{all PLAN.md contents}

## Review Instructions

**Verify against source — do not review the plan text in isolation.** The plans reference real files, migrations, routes, and tests in this repo.
1. Open the referenced files and check each claim against the actual code.
2. For every strength or concern, cite concrete `path/to/file:line` evidence plus the mechanism.
3. When a plan asserts a mechanism works (a guard, a query filter, a test that exercises a path), trace whether it actually does what is claimed — do not take the plan's word for it.
4. If you cannot read the repo (no file access), say so and downgrade that finding to an open question rather than asserting it.

Findings citing `file:line` evidence are weighted far more heavily than impressionistic ones; a review that only restates the plan's own claims has low value.

Analyze each plan and provide:

1. **Summary** — One-paragraph assessment
2. **Strengths** — What's well-designed (bullet points)
3. **Concerns** — Potential issues, gaps, risks (bullet points with severity: HIGH/MEDIUM/LOW)
4. **Suggestions** — Specific improvements (bullet points)
5. **Risk Assessment** — Overall risk level (LOW/MEDIUM/HIGH) with justification

Focus on:
- Missing edge cases or error handling
- Dependency ordering issues
- Scope creep or over-engineering
- Security considerations
- Performance implications
- Whether the plans actually achieve the phase goals

Write to a temp file: {run_dir}/gsd-review-prompt.md

Also write individual section files so the budget tool can re-trim per reviewer:

RUN_DIR="{run_dir}"   # from gather_context

# Write individual section files for per-reviewer budget trimming
# These are always written so reviewers with a budget can invoke prompt-budget
cp "$INSTRUCTIONS_BLOCK_FILE" "${RUN_DIR}/gsd-review-instructions.md"

# Plan files: copy each PLAN.md to a predictable numbered path
PLAN_INDEX=0
for PLAN_FILE in "${PHASE_DIR}"/*-PLAN.md; do
  PADDED_IDX=$(printf '%02d' "$PLAN_INDEX")
  cp "$PLAN_FILE" "${RUN_DIR}/gsd-review-plan-${PADDED_IDX}.md"
  PLAN_INDEX=$((PLAN_INDEX + 1))
done

# Optional section files (only if content was included in the combined prompt)
if [ -f ".planning/PROJECT.md" ]; then
  cp .planning/PROJECT.md "${RUN_DIR}/gsd-review-project.md"
fi
if ls "${PHASE_DIR}/"*"-CONTEXT.md" >/dev/null 2>&1; then
  cat "${PHASE_DIR}/"*"-CONTEXT.md" > "${RUN_DIR}/gsd-review-context.md"

if [ -f ".planning/REQUIREMENTS.md" ]; then
  cp .planning/REQUIREMENTS.md "${RUN_DIR}/gsd-review-requirements.md"
fi

Note: INSTRUCTIONS_BLOCK_FILE, ROADMAP_SECTION_FILE, and PHASE_DIR come from prompt assembly; RUN_DIR is the run-scoped dir from gather_context (#2358) re-assigned from {run_dir} above. Copy the temp files written during prompt assembly to these section paths (or write each section here if the prompt was built inline).

No hook-trust bypass (#2479): the codex invocations below deliberately pass no hook-trust bypass flag and run no capability probe for one (#1115's former gate). That flag only bypasses persisted hook trust (a first-run condition) and flagless invocations work in steady state, while host-harness safety classifiers deny commands carrying it — and cited the probe itself as intent (#2479). An environment that genuinely hits an untrusted-hook prompt surfaces through the .err capture + empty-output guard below as a dropped lane with diagnosable stderr, not silent attrition. Do not reintroduce the flag (even spelled out in prose here — a regression test bans the literal file-wide) or the probe; the #1115 "unexpected argument" failure mode existed only because the flag was emitted, so with no flag there is nothing to version-gate.

Reviewer instances (#1517, optional): when instances are configured, each selected instance invokes its base cli with its own model/agent (opaque argv, never shell-interpolated). Exact invocation in gsd-core/references/reviewer-instances.md.

For each selected CLI, invoke in sequence (not parallel — avoid rate limits):

Timeout guidance (#2194): prompt-fed source-grounded reviews are slow — measured ~570s for Codex at xhigh effort and ~525s for headless Claude on a large plan set. Each of the Gemini / Claude / Codex blocks below MUST be invoked with a high Bash timeout: — at least 900000 (15 min), and 1200000 (20 min) for Codex xhigh or headless Claude — so a lane is not killed mid-review. On Claude Code, raise the host cap via BASH_MAX_TIMEOUT_MS if a review can exceed it. A silent empty output after a long run is a timeout kill, not a crash — the Codex 0xc0000142 misdiagnosis persisted because the empty-output branches below cannot distinguish the two; treat an empty result on a slow lane as a dropped lane and re-run with more time rather than diagnosing a CLI/sandbox failure. A cross-AI review that silently drops a lane is blind in one eye.

Gemini:

# #2494: capture stderr to a .err sidecar (not /dev/null) and stub an empty
# result, mirroring the Codex and Cursor blocks. Without the guard a failed
# lane — CLI missing, unauthenticated, rate-limited, crashed, or any exit that
# writes no stdout — leaves a zero-byte file that write_reviews renders as a
# reviewer that ran cleanly with nothing to report, silently dropping a lane
# from the cross-AI consensus while present_results reports success.
# Scope limit: the guard only runs if this block completes. A host Bash-tool
# timeout that kills the whole block skips it, the same hard bound the
# OpenCode block documents below — per the timeout guidance above, treat an
# empty result on a slow lane as a dropped lane rather than a crash.

CodeRabbit:

Note: CodeRabbit reviews the current git diff/working tree — it does not accept a prompt or model flag. It may take up to 5 minutes. Use timeout: 360000 on the Bash tool call. The source-grounding requirement in the build_prompt Review Instructions applies only to the prompt-fed reviewers above; CodeRabbit is a diff-only reviewer and never receives it. Treat its output as a diff observation, not a grounded plan-level verdict.

coderabbit review --prompt-only 2>/dev/null > {run_dir}/gsd-review-coderabbit.md

OpenCode (via GitHub Copilot):

OpenCode's default build agent is an agentic coder, not a prompt→completion API. On a large review prompt it may run a few read tool calls and then end its turn with zero output tokens (reason:"stop", output:0), so --format default yields empty stdout and the second reviewer is silently lost (#1936). Invoke with --format json and reconstruct the review from the assistant text parts; if the agent emitted none, surface the stop reason, output-token count, and captured stderr so the failure is diagnosable instead of a generic empty stub. Runs are also nondeterministic in length, so bound this Bash tool call with a wall-clock timeout — set timeout: 660000 on the call (same mechanism the CodeRabbit block documents). That bound is hard: if it fires mid-opencode run the tool kills the command and the jq reconstruction below never runs, so the reviewing agent simply proceeds without an OpenCode result. The completing zero-output case — the actual #1936 bug — is fully handled below; the timeout only backstops the rarer nondeterministic hang. A reviewer instance with "agent": "review" (see gsd-core/references/reviewer-instances.md) sidesteps the default build agent and is the durable fix when this recurs.

# stderr → sidecar (never /dev/null) so a real error is diagnosable — mirrors the
# Codex block. --format json is the primary invocation (not a fallback): the review
# text lives in assistant `text` parts, which the default formatter drops when the
# agent stops with no final message (#1936).

Antigravity CLI:

Maintainer note — why this block has three layers (last updated against agy 1.0.16):

agy -p (the --print non-interactive flag) works correctly on macOS and Linux: it sends the prompt, receives the model response, and writes it to stdout. On native Windows it silently produces no stdout output despite the API call succeeding — a bug in text_drip.go's non-TTY flush path, tracked at https://github.com/google-antigravity/antigravity-cli/issues/27466 and still open as of agy 1.0.2.

Regardless of platform, agy always persists the full exchange to a transcript file on disk. The transcript fallback (Step 2 below) reads that file directly, giving Windows users full review coverage without any extra tooling. This pattern was first documented by the community MCP bridge at https://github.com/SinanTufekci/Claude-Code-Antigravity-CLI-MCP-Server — we inline the same logic here in pure bash/jq so no additional dependency is required.

Stale-response guard (why the pre-flight watermark matters): Without a watermark, the fallback would read the last PLANNER_RESPONSE entry in the transcript regardless of when it was written — including entries from a previous invocation in the same workspace. To prevent that, we record the transcript's line count before calling agy -p. In the fallback, we only read lines appended after that count. If no new lines were written (agy failed before producing a response), _AGY_RESULT is empty and Step 3 fires — never stale. If the conv-id changed (agy started a fresh session), all lines in the new file are new and we use skip=0.

If the upstream stdout bug is fixed (check the issue above): Step 2 silently becomes unreachable; stdout is non-empty and Step 1 handles it. No code change needed.

If the transcript paths change in a future agy release: Step 2 silently becomes a no-op and Step 3 fires with a clear error message in REVIEWS.md. No silent corruption. To debug:

• ~/.gemini/antigravity-cli/cache/last_conversations.json — workspace → conv-id map
• ~/.gemini/antigravity-cli/brain/<id>/.system_generated/logs/transcript.jsonl Filter: source=="MODEL", status=="DONE", type=="PLANNER_RESPONSE", take the last match's content field.

Invocation specifics (verified agy 1.0.0, macOS arm64 and Linux amd64):

• -p takes the prompt as a flag value — echo X | agy -p errors with "flag needs an argument: -p"
• --print-timeout defaults to 5m, aligning with this workflow's global timeout
• --model "<name>" selects the model (available since agy ~1.0.3; agy models lists them). When review.models.agy is set it is passed as --model; otherwise agy uses its persisted default (agy models).

# Pre-flight: snapshot the transcript watermark before invoking agy.
# Must run BEFORE agy -p — this is what prevents the fallback from reading a stale prior response.

# Step 1 — primary invocation: stdout works on macOS, Linux, and WSL.

#   * FILE-REFERENCE prompt (not inline `$(cat …)`) — a large review prompt (≈197 KB
#     for 6 plans + CONTEXT + RESEARCH + REQUIREMENTS) overflows the exec arg list
#     (`bash: agy: Argument list too long`, rc 126), indistinguishable from a model
#     failure when stderr is suppressed.
#   * EXTERNAL `timeout` wrapper when available (GNU `timeout` / `gtimeout`) —
#     `--print-timeout` is agy's native cap but it CANNOT fire before agy creates a
#     session; under concurrent heavy runs one process can stall pre-session (no
#     `brain/<conv-id>/` dir, alive at 583 s despite `--print-timeout 300s`). The
#     external cap bounds wall-clock regardless. Stock macOS lacks `timeout`, so
#     the block probes for it and falls back to --print-timeout alone there.
#   * `--model` from `review.models.agy` when set — escape hatch for a pinned model
#     that 404s server-side (exits 0 with empty stdout AND empty transcript).
#   * stdin tied to /dev/null so agy never blocks on a tty.
# A non-zero exit (external timeout = 124, crash, etc.) discards any partial output
# so the Step 2 transcript fallback / Step 3 diagnostic take over.

◆ Reviewing with {CLI}... done ✓

Combine all review responses into `{phase_dir}/{padded_phase}-REVIEWS.md`:

After all reviewers complete, collect trim metadata files written during the run. For each reviewer that was trimmed (i.e. a .metadata.json file exists and hardFailed or omitted is non-empty, or projectMdShrunk is true, or planTruncationPct > 0), include a trimmed_reviewers block in the frontmatter. Omit the key entirely if no reviewer was trimmed.

Reviewer instances (#1517, optional): when instances ran, frontmatter records their names, each gets its own ## <Adapter> Review (<instance>) section, and ≥2 same-cli instances print a one-line shared-adapter caveat. Format in gsd-core/references/reviewer-instances.md.

## Consensus Summary

{synthesize common concerns across all reviewers. CodeRabbit is a diff-only reviewer (it never received the source-grounding prompt), so do not weight its verdict as a grounded plan review — fold in its diff findings, but base plan-level consensus on the prompt-fed reviewers. A reviewer output carrying the `[reviewed-without-repo-access]` marker (or beginning with `REVIEWED-WITHOUT-REPO-ACCESS`) ran without repo access (#2176) — treat it the same way: note its concerns, but do not count its verdict at full consensus weight.}

### Agreed Strengths
{strengths mentioned by 2+ reviewers}

### Agreed Concerns
{concerns raised by 2+ reviewers — highest priority}

### Divergent Views
{where reviewers disagreed — worth investigating}
