# Agent Skills A curated source repo for agent skills and plugin bundles. This repo is organized around the open Agent Skills CLI (`npx skills`) instead of local sync scripts: - `plugins/`: plugin manifests that bundle a set of top-level skills (AgentRig distribution is not ready yet — install bundled skills individually for now). - `skills/`: all installable skills, both standalone and the ones referenced by a plugin bundle. Each can be listed and installed independently. - `internal/`: personal or experimental workflows that are not part of the public install surface. ## Install Use the open Agent Skills CLI. List everything in the repo, then install per skill: ```bash # List skills in this repo npx skills add instructa/agent-skills --list ``` Use `-g` for a global install, or omit it for a project-local install. Add `--copy` if you prefer copied files instead of symlinks.

## Skills ### `regenrek.agentic-engineer-core` Core agentic engineering skills for architecture, debugging, refactoring, and test ownership. Bundled skills live in the top-level `skills/` folder; the plugin manifest (`plugins/regenrek.agentic-engineer-core/.plugin/plugin.json`) declares which ones are part of the bundle. Each skill also has its own `README.md`. Plugin category: `Development`. Architecture / Ownership: - `architecture-ownership`: determine the right runtime, first-fix, and canonical long-term owner. - `find-duplicate-ownership`: audit duplicate ownership and hidden second sources of truth. - `hard-cut`: keep one canonical implementation during pre-release refactors. Debugging / Investigation: - `root-cause-finder`: trace downstream errors to the first unintended side effect. - `search-context`: search external repositories and reference code before guessing. Testing: - `consolidate-test-suites`: place bug-fix coverage in one owning test layer. ### Standalone Skills These skills are kept as separate artifacts because they are useful independently. Each skill folder also has its own `README.md`. - `app-spec-packager`: create production-ready app specification packages for coding agents. - `debug-lldb`: capture and analyze LLDB/GDB backtraces for hangs and high-CPU loops. - `gh-repo-bootstrap`: create a GitHub repo and bootstrap a local project. - `git-safe-workflow`: inspect, stage, commit, and push safely when explicitly requested. - `gitwhat`: print a compact git workspace snapshot. - `go-local-health`: run local Go test, coverage, and lint health checks. - `homebrew-publish`: prepare Homebrew tap formulae for CLI/TUI releases. - `no-mistakes`: use the no-mistakes gated push workflow. - `package-security-check`: run a reusable JavaScript supply-chain security baseline. - `redesign-my-landingpage`: build and critique shadcn/Vite/Iconify landing pages. - `secleak-check`: run BetterLeaks/Trivy scans and add secret-leak guardrails. - `shellck`: run shellcheck over shell scripts. - `stage-review`: commit a finished feature locally, then run it through no-mistakes. ## Repository Layout ```text plugins/ regenrek.agentic-engineer-core/ .plugin/plugin.json # declares which top-level skills are in the bundle README.md skills/ app-spec-packager/ architecture-ownership/ # bundled in regenrek.agentic-engineer-core consolidate-test-suites/ # bundled in regenrek.agentic-engineer-core debug-lldb/ find-duplicate-ownership/ # bundled in regenrek.agentic-engineer-core hard-cut/ # bundled in regenrek.agentic-engineer-core root-cause-finder/ # bundled in regenrek.agentic-engineer-core search-context/ # bundled in regenrek.agentic-engineer-core ... internal/ codex-analysis/ codex-sandbox/ create-new-static-website/ pr-commiter/ ``` ## Links - X/Twitter: [@kregenrek](https://x.com/kregenrek) - Bluesky: [@kevinkern.dev](https://bsky.app/profile/kevinkern.dev) - Learn Cursor AI: [Ultimate Cursor Course](https://www.instructa.ai/en/cursor-ai) - Learn to build software with AI: [AI Builder Hub](https://www.instructa.ai)
