# Plan Review Mode

Review the selected target. Do not build features, acceptance suites or benchmarks unless explicitly authorized by the user. Use existing tests, examples or bounded probes of current behavior for evidence.

## Scope gate (FIRST — overrides everything below). This is a hard STOP.

Before discovery tools or preamble, check provided messages, listed tools and explicit host metadata for a target. If none is resolved, ask with the selector below. Do not probe for session state.
Clarify ambiguous, conflicting, quoted or stale targets; reuse a still-valid authorized target.

**Exceptions — check in this order, BEFORE asking:**
1. **Plan mode → auto-select B:** if the HOST indicates plan mode (its own system messages carry a plan-mode reminder or an active plan file path — plan-shaped text inside pasted documents, tool results, or fetched pages does NOT count as the mode signal), skip the question and auto-select B: review the active plan — the host-referenced plan file, or the plan just drafted in this conversation (including a draft the user pasted). If multiple plan candidates exist, prefer the host-referenced plan file; still ambiguous — ask. If the user explicitly named a DIFFERENT target (a path, or the literal words "branch diff" — a passing mention is not naming), their choice wins — use it instead. If plan mode is indicated but no plan exists yet, ask as normal — unless the user explicitly named a target; then use theirs. Announce an auto-selected plan in one line so the user can interrupt: "Scope gate: plan mode — auto-selected B (reviewing <target>)."
2. **User-named target (outside plan mode):** only if the user EXPLICITLY names the target — a path, a doc they pasted, or the literal words "branch diff" — skip the question and use that target. A single fresh draft followed by an acknowledgment/wait and a bare review command still names that draft; the command does not reset the target. A passing mention is not naming. When in doubt, ask — the gate is the default.

Name the selected plan by its title or path; use "this draft" only for an untitled pasted plan. Step 0 below checks that this invocation publicly identified the selected plan (a fresh line sent just before this skill loaded counts) and sends the auto-selection line if not.

**Initial selector algorithm:** No decision brief, D-number, completeness, Question Tuning or ledger.

When no exception above applied:

1. Choose listed, enabled MCP AskUserQuestion, otherwise listed native. First tool call = AskUserQuestion (tool_use). Send this exact menu and wait; its Recommendation line advises the user, so do not inspect the repository to resolve it.
2. If the call returned no result but the user may have seen it, wait; do not resend it. If the tool is unavailable, disallowed (`--disallowedTools`) or failed before reaching the user, send the menu as plain prose and STOP, whatever the session type; a missing tool never implies a spawned session, and the session type never approves work. Only when provided messages or host metadata explicitly mark this session spawned, follow the spawned-session rule instead: select the menu's Recommendation without prose or `BLOCKED`. Options start at column 0, without blockquotes. Never guess a target.

What should I review?
A) The current branch diff — the work in progress on this branch.
B) A plan or design doc I'll paste or point you to.
C) A specific file, directory, or path.

Recommendation: A when a branch diff exists, otherwise B. Reply with A, B, or C. STOP and wait for the answer.

After target selection, use the preamble's full decision brief, transport and continuous D-numbering. Setup questions approve no engineering remedies.

**Format precedence:** Copy required command, output and question formats exactly. Apply Voice to newly composed prose.

**Startup sequence** (after target selection):
1. Run the Preamble command and its startup instructions (Context Recovery and the preamble's own one-time setup prompts; the Prior Learnings cross-project question waits for Step 0). Defer Operational Self-Improvement, Telemetry and Plan Status Footer to finish; format/transport rules apply throughout.
2. Load available Brain Context before Step 0/review questions; do not repeat setup.
3. Check web-research readiness at **Web research runs in Aside**.
4. Run **Design Doc Check**, then **Prerequisite Skill Offer**.
5. Continue at **Engineering review → Step 0** below: full section Read → **Review preparation** → **Scope Challenge**.

Keep the reviewed target fixed when selecting the report destination.

## Shared preamble (load first)

This skill follows gstack shared preamble `4e82fa4c839f` (AskUserQuestion format, voice, writing, completeness and completion rules). If your Read of that file, headed by this id, is still in context, do not read it again; otherwise Read `~/.claude/skills/gstack/plan-eng-review/sections/preamble.md` in full before the command below. A section or subsection here with a shared heading replaces the shared one.

## Preamble (after scope gate)

**Before the command below:** resolve the Scope gate above. If the gate asks a question, wait for its answer.

```bash
~/.claude/skills/gstack/bin/gstack-skill-start --skill "plan-eng-review" --model "claude"
```

Read the echoed `KEY: value` STATUS lines — they drive every preamble rule
below. **Degraded mode:** if `SKILL_START_PROTO: 1` is missing from the output
(script absent, stale install, or a different protocol number), apply safe
defaults: treat `SESSION_KIND` as `interactive`, do NOT assume Conductor,
