What problem does it solve? Running codex review non-interactively can hang indefinitely when it inherits locally configured MCP servers, and a review without a scope prompt reports work the change deliberately omitted. This Skill encodes the correct invocation so the local pre-PR review pass completes reliably. ## Core Features & Use Cases - Scoped branch review: Builds a Scope Brief prompt (verbatim request, in/out of scope, established facts) and passes it to codex review, since scope flags and a custom prompt are mutually exclusive. - MCP hang prevention: Disables every locally configured MCP server individually by name via codex mcp list --json, treating enumeration failure as a setup failure rather than running unprotected. - Completion contract: The bundled script always ends with a STATUS= line (COMPLETED, DRY_RUN, ERROR) plus CODEX_EXIT=, so callers branch on a sentinel instead of guessing from exit codes. - Use Case: Before opening a pull request, run the script in the background with a scope prompt file; when it finishes, read the findings and triage them per the canonical fx-review procedure. ## Quick Start Ask the agent to run a scoped Codex review of the current branch using the codex-review skill's script with a scope prompt built from your request.
