It covers the complete plugin lifecycle: scaffold a new plugin from heurema-standard templates, run six sequential validators to catch schema errors, missing files, and unsafe hook scripts before you publish, and execute fixture-driven hook tests to verify runtime behaviour. A built-in code-review agent applies a 21-item quality checklist and returns an explicit APPROVE or REQUEST CHANGES verdict. Everything runs locally — no network, no credentials.\n\n## Install\n\n\u003c!-- INSTALL:START -- auto-synced from emporium/INSTALL_REFERENCE.md --\u003e\n```bash\nclaude plugin marketplace add heurema/emporium\nclaude plugin install anvil@emporium\n```\n\u003c!-- INSTALL:END --\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eManual install (from source)\u003c/summary\u003e\n\n```bash\ngit clone https://github.com/heurema/anvil.git ~/.claude/plugins/anvil\n```\n\nThen add to `~/.claude/settings.json`:\n\n```json\n{\n  \"permissions\": {\n    \"allow\": [\"Bash(~/.claude/plugins/anvil/hooks/*)\"]\n  }\n}\n```\n\nOpen a new Claude Code session to activate.\n\n\u003c/details\u003e\n\n## Quick start\n\n```\n/anvil:new my-plugin\n/anvil:check ./my-plugin\n/anvil:test  ./my-plugin\n```\n\n## Commands\n\n| Command | What it does |\n|---------|-------------|\n| `/anvil:new` | Scaffold a complete plugin skeleton from heurema-standard templates |\n| `/anvil:check` | Run six sequential validators and return a single PASS/FAIL verdict |\n| `/anvil:test` | Execute fixture-driven hook tests to verify runtime behaviour |\n\n## Features\n\n- **Scaffolding** — `/anvil:new` generates a conventions-compliant plugin skeleton (plugin.json, README, LICENSE, CHANGELOG, .gitignore); optionally initialises a git repo and creates a GitHub repository under the heurema org.\n- **Six-layer validation** — `/anvil:check` runs schema, structure, hooks, conventions, consistency, and install-docs validators in sequence and aggregates results into a JSON report.\n- **Fixture-driven hook testing** — `/anvil:test` executes `scripts/test_hooks.py` against your hook scripts and checks skill descriptions for presence, voice, length, and keywords.\n- **AI code review** — The `anvil-reviewer` agent (sonnet, read-only) applies a 21-item checklist and gives an unambiguous APPROVE or REQUEST CHANGES verdict.\n- **Zero network dependency** — all validation and scaffolding is local; the optional `gh repo create` step is explicit and opt-in.\n\n## Requirements\n\n- Claude Code with plugin support\n- Python 3.14+ (for validator scripts and test framework)\n- `jq` (for hook validators)\n- `gh` CLI — optional, only needed if you want `/anvil:new` to create a GitHub repository\n\n## Privacy\n\nAnvil makes no network calls during validation or scaffolding. No plugin files, metadata, or diagnostic output leave your machine. The optional GitHub repository creation step in `/anvil:new` uses your local `gh` CLI and is gated behind an explicit confirmation prompt.\n\n## See also\n\n- [skill7.dev](https://skill7.dev) — plugin catalog and docs\n- [emporium](https://github.com/heurema/emporium) — the heurema marketplace\n- [forge](https://github.com/heurema/forge) — plugin publishing and release pipeline\n- [signum](https://github.com/heurema/signum) — risk-adaptive development pipeline with adversarial consensus code review\n\n## License\n\n[MIT](LICENSE)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fheurema%2Fanvil","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fheurema%2Fanvil","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fheurema%2Fanvil/lists"}
