Explain plugin, skill, command, agent, and hook mechanics used here. Use when authoring or debugging plugins. Do not use for ops; use night-market-operations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Claude Code Plugin Reference (night-market edition) This is the domain pack for how Claude Code plugin machinery works in this repository. It covers manifests, skills, commands, agents, hooks, and the marketplace registry, with the local conventions layered on top. Every contract below was checked against a shipped plugin (mostly `plugins/imbue`, `plugins/abstract`, and `plugins/herald`) on 2026-07-02 at repo v1.9.15. When another night-market skill says "see the plugin reference for what a hook payload is," this is the file it means. ## Vocabulary Each term is defined once here and used without redefinition below. | Term | Meaning in this repo | |------|----------------------| | Plugin | A directory under `plugins/` shipping skills, commands, agents, and hooks, with its own tests, Makefile, and pyproject.toml. Independently deployable (ADR-0001). | | Skill | A directory `skills/<name>/` containing `SKILL.md`. Loaded by the model on demand, invoked as `Skill(plugin:name)`. | | Module | A file under a skill's `modules/` subdirectory. Loaded only when the hub `SKILL.md` routes to it (progressive loading). | …

How to install
mdr add athola/claude-night-market/claude-code-plugin-reference@sha256:a4791ae66cab2e57The line at the top of this page pins the label git:20261005.d8ad765, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
