How mods are built in THIS repo - where a mod's files live (mods/<name>/, not ~/.claude/dev-mods), how to load and hot-reload it, the validate / type-check / test loop, the static-analysis rules `claude plugin validate` enforces, and test-kit gotchas. Load together with the built-in `plugin-authoring` skill whenever creating, editing, testing, debugging or shipping a Claude Code mod here.
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
# Building mods in this repo
`plugin-authoring` (built into Claude Code) is the authority on the mods API: load it first, every time. It names the type declarations for the running build (a ~20k-line `claude-code.d.ts`), and those beat any doc, this file included. This skill covers only what that skill leaves open: where mods live in this repo, and the gotchas we've already hit.
## Where a mod lives: override plugin-authoring's WHERE TO WRITE IT
`plugin-authoring` writes a mod into the session-scoped `~/.claude/dev-mods/<session-id>/`, and Claude Code deletes that folder after `cleanupPeriodDays`. In this repo the mod's home is the git tree:
```
mods/<mod-name>/
├── .claude-plugin/
│ ├── plugin.json # name, version, description, author, userConfig, "types" if it has a contract
│ └── types/ # GENERATED by the engine on every load: gitignored, never edit
├── hooks/
│ ├── hooks.json # { "modules": ["./register.ts"] }
│ └── register.ts(x) # export const register: Register = (on, options) => { ... }
├── types/index.d.ts # only when the mod keeps $.state: the PluginState contract

How to install
mdr add leopiney/wolfbud-claude-mod/mod-dev@sha256:cd70f7690c4c2af1The line at the top of this page pins the label git:20261006.2b3ddb9, 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.
