The skill lived at the repository root, which the CLI reads as a single-skill repository and which makes a second skill impossible to add. SKILL.md, references/ and scripts/ move under skills/apk-reverse/ with git mv, so history follows and no in-skill reference needs changing (they are relative to SKILL.md). check_repo.py now discovers every skills/*/SKILL.md, validates frontmatter by parsing it instead of pattern-matching it, and requires the README to name skills through explicit skills/<name>/... paths. check_refs.py is new: it audits file.md section cross-references against the real headings in the target file. It found six dangling ones, all fixed here. SKILL.md: the description is now quoted. Unquoted, it contained a colon-space, which is invalid YAML, so the CLI skipped the skill and reported No skills found. Adds a Coverage section stating what is out of scope and what to do when nothing matches. toolchain.md: IDA is not GUI-only (idalib-mcp is a headless MCP server), plus a section on MCP servers as external dependencies and the deobfuscate-before-LLM boundary. README.md: install via npx skills add, the new layout, coverage and maintenance tools. Verified: check_repo.py and check_refs.py both clean, build_scripts.py audit 0 findings, npx skills add . --list reports apk-reverse, and an install into a scratch directory lands SKILL.md plus 28 references and 38 scripts.

"""Pre-commit checks for this repository.
|
|
|
|
Assumed layout -- the one the `skills` CLI resolves:
|
|
|
|
README.md repository-level docs (root)
|
|
skills/<skill-name>/SKILL.md the skill itself
|
|
skills/<skill-name>/references/*.md loaded on demand
|
|
skills/<skill-name>/scripts/* run, not read
|
|
|
|
Every skill under `skills/` is discovered automatically (up to three levels;
|
|
a SKILL.md at a shallower level shadows anything nested below it, which is the
|
|
CLI's own rule), so adding a second skill requires no change to this script.
|
|
|
|
Per skill:
|
|
1. frontmatter exists, `name` matches the directory name, `description` <= 1024
|
|
2. every scripts/*.py parses and answers --help without a traceback
|
|
3. every `references/X.md` / `scripts/X.py` reference resolves inside that skill
|
|
4. every reference file is reachable from that skill's SKILL.md or the README
|
|
5. every script is mentioned somewhere in the docs
|
|
|
|
On the root README:
|
|
6. every path it names is an explicit `skills/<name>/...` path that exists
