<objective>
Invoke external AI CLIs (Gemini, Claude, Codex, OpenCode) to independently review phase plans.
Produces a structured REVIEWS.md with per-reviewer feedback that can be fed back into
planning via /gsd-plan-phase --reviews.

**Flow:** Detect CLIs → Build review prompt → Invoke each CLI → Collect responses → Write REVIEWS.md
</objective>

<purpose>
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.
</purpose>

<step name="detect_clis">
Check which AI CLIs are available on the system:

```bash
# Check each CLI
command -v gemini >/dev/null 2>&1 && echo "gemini:available" || echo "gemini:missing"
command -v claude >/dev/null 2>&1 && echo "claude:available" || echo "claude:missing"
command -v codex >/dev/null 2>&1 && echo "codex:available" || echo "codex:missing"
command -v coderabbit >/dev/null 2>&1 && echo "coderabbit:available" || echo "coderabbit:missing"
command -v opencode >/dev/null 2>&1 && echo "opencode:available" || echo "opencode:missing"
```

Parse flags from `$ARGUMENTS`:
- `--gemini` → include Gemini
- `--claude` → include Claude
- `--codex` → include Codex
- `--coderabbit` → include CodeRabbit
- `--opencode` → include OpenCode
- `--all` → include all available
- No flags → include all available

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)

Then run /gsd-review again.
```
Exit.

If only one CLI is the current runtime (e.g. running inside Claude), skip it for the review
to ensure independence. At least one DIFFERENT CLI must be available.
</step>

<step name="gather_context">
Collect phase artifacts for the review prompt:

```bash
INIT=$(node "$GSD_TOOLS" init phase-op "${PHASE_ARG}")
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi
```

Read from init: `phase_dir`, `phase_number`, `padded_phase`.

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)
</step>

<step name="build_prompt">
Build a structured review prompt:

```markdown
# 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

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

Output your review in markdown format.
```

Write to a temp file: `/tmp/gsd-review-prompt-{phase}.md`
</step>

<step name="invoke_reviewers">
For each selected CLI, invoke in sequence (not parallel — avoid rate limits):

**Gemini:**
```bash
gemini -p "$(cat /tmp/gsd-review-prompt-{phase}.md)" 2>/dev/null > /tmp/gsd-review-gemini-{phase}.md
```

**Claude (separate session):**
```bash
claude -p "$(cat /tmp/gsd-review-prompt-{phase}.md)" --no-input 2>/dev/null > /tmp/gsd-review-claude-{phase}.md
```

**Codex:**
```bash
codex exec --skip-git-repo-check "$(cat /tmp/gsd-review-prompt-{phase}.md)" 2>/dev/null > /tmp/gsd-review-codex-{phase}.md
```

**CodeRabbit:**

Note: CodeRabbit reviews the current git diff/working tree — it does not accept a prompt. It may take up to 5 minutes. Use `timeout: 360000` on the Bash tool call.

```bash
coderabbit review --prompt-only 2>/dev/null > /tmp/gsd-review-coderabbit-{phase}.md
```

**OpenCode (via GitHub Copilot):**
```bash
cat /tmp/gsd-review-prompt-{phase}.md | opencode run - 2>/dev/null > /tmp/gsd-review-opencode-{phase}.md
if [ ! -s /tmp/gsd-review-opencode-{phase}.md ]; then
  echo "OpenCode review failed or returned empty output." > /tmp/gsd-review-opencode-{phase}.md
fi
```

If a CLI fails, log the error and continue with remaining CLIs.
