// Fill test coverage gaps to hit the project's target (AGENTS.md says ≥80% on src/). Reads existing tests to match style, prioritizes public-API and error paths, runs the suite after every batch.
Use ast-grep for structural (AST-aware) code search and refactoring instead of plain ripgrep when the intent depends on code structure — not just text matching. Triggers on refactors, codemods, "find all X that don't Y", or any search where naive grep would miss edge cases.
Guides proactive /compact usage with preservation instructions to prevent context rot in long Cascade sessions. Triggers when context reaches ~50% of window, before large tool outputs, or when the user mentions "context", "compact", "drift", or "forgetting".
Use when any non-trivial task (>20 LOC or >1 file) would otherwise be done without a persistent plan. Produces and maintains a markdown plan file that survives session compaction and restarts. Based on the Manus-style planning pattern popularized by OthmanAdi/planning-with-files (18.4k⭐).
Turn a feature branch into a clean, reviewable PR. Squash WIP commits, polish messages, verify green checks, draft PR description. Invoke right before opening a PR.
Scan a diff, branch, or working tree for leaked secrets, API keys, tokens, private keys, and PII before commit. Blocks the operation on CRITICAL findings, warns on MEDIUM. Pairs with the pre_commit hook.
Read the project wiki (vault/) before starting any non-trivial task. Surfaces relevant decisions, ownership, incidents, and glossary entries for the task at hand.

Raise coverage without shipping bad tests.
A good test:
A bad test:
try/catch instead of expect().toThrow() (or equivalent).expect(true).toBe(true) stubs)sleep(N) — use a proper wait-for-condition utility@integration tag.skip without a dated TODO and an owner.
