It knows 84 +patterns in 9 categories and parses frontmatter as data, so a skill with `allowed-tools: "*"` or a +hook that curls and executes a script is flagged structurally, not by keyword. There is a pre-commit +hook (`injection-scanner install-hook`) and a PostToolUse hook example for Claude Code in +`integrations/claude-code/`. + +The numbers: 105/115 (91%) on the corpus it was built against, and 2/12 (17%) on a sealed held-out +set for the newest category.

Default. +2. **Crate contents.** (a) Keep `tests/` + corpus (1.0 MB) and exclude `.planning/` and the reference + docs, crate about 230 files, well under 10 MB; or (b) source-only. (a) is the default: the corpus + is the evidence behind the published numbers and lets a `cargo` user run `recall_test`. +3. **Version and milestone.** The GitHub milestone `v0.3.0` holds 36 open detection-gap issues with + no plan or date. Default: rename it `v0.4.0: detection gaps` and ship this as v0.3.0 (new install + channels justify a minor bump).
