# 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.
