Pre-commit security validation and secret detection via gitleaks. Use when scanning for secrets, setting up gitleaks, or configuring .gitleaks.toml pre-commit security.
Multi-repo workspace rules: read-only fixtures, upstream/downstream pairs. Use when dispatching agents across sibling repos or editing another repo's .claude/.
Check and configure Justfiles with standard recipes. Use when setting up a Justfile, auditing for missing recipes, or migrating from Makefile to Justfile.

Read an issue's full comment thread and re-verify its cited evidence at HEAD. Use when scoping a PR or plan from a GitHub issue, or before filing or reversing one in your own tracker.
Test-fix-refactor loop that edits code between runs until the suite is green, bounded by --max-cycles. Use when asked to make failing tests pass or drive a TDD RED/GREEN/REFACTOR cycle.
One test file, fail-fast — Playwright, Vitest, Jest, pytest, cargo, go test. Use when running a single spec file, headed/debug mode, or serial single-worker WebGL tests.
