Development Claude Skills
8 673 development skills from 759 authors. They write and change code. Half of them fit into 1 830 tokens or less — that is what one costs your context window when the agent loads it. 1 213 ship runnable scripts rather than instructions alone. 42 of them cannot work without an MCP server, most often rube. We also found 1 239 copies of these same skills sitting in other people's repositories — counted once here, not 1 239 times.

| Read-only audit of GitHub Actions workflow runner compatibility for one repository, an explicit repository set, one Apache project with multiple repositories, or the full Apache GitHub org. Finds obsolete GitHub-hosted runner labels and macOS runner/tool architecture mismatches. Produces TSV evidence files; never edits workflows, opens PRs, or posts comments.
| Read-only dependency vulnerability audit for one repository or a local checkout. Detects the project's dependency manager(s), runs the appropriate audit tool, surfaces patchable findings grouped by severity, and proposes upgrades for maintainer review. Never modifies manifests or lock files and never opens update PRs.
| Read-only flaky-test detection from GitHub Actions CI run history for one repository. Parses workflow run outcomes over a configurable window, computes per-job failure rates, and distinguishes intermittent failures (flaky) from consistent failures (deterministically broken). Produces a prioritised triage list without modifying any test code, workflow file, or tracker state.
| Read-only license audit of a project's direct and transitive dependency tree. Detects the dependency manager(s), resolves each dependency's declared license from ecosystem metadata, classifies each against a configured policy (ASF three-category A/B/X model or a custom allowlist), and surfaces incompatible, forbidden, and unknown-license dependencies for maintainer review. Never modifies manifests or lock files.
| For a single `<issue-tracker>` issue identifying a code-level bug, extract the reporter's example code from the issue body, adapt it to run on the current `<default-branch>`, execute via `<runtime>`, and compose a `verdict.json` describing the observed behaviour vs the expected failure. Read-only on the tracker — produces evidence, never posts. Invoked by `issue-triage` and `issue-reassess`; can also be run standalone.
| For each open `<issue-tracker>` issue in the configured candidate pool, read the issue body and comments and classify the candidate disposition. On user confirmation, posts a triage-proposal comment that invites the project team to react. Read-only on tracker state — no workflow transitions, closures, or label changes. Six classes in the body.
