naudachu 01fb5a2703 feat: publish releases with this repository's own SDK code
There is no CI: the instance has no act_runner and none is planned, so releases
are cut by hand. That makes `make check` the only thing standing between a
mistake and the tracker, and it is one command: gofmt, vet, the suite with the
cache defeated, `go mod verify`, a vendored build, and `kettle gen skills
--check`. The last one is the invariant worth having — the plugin's SKILL.md
command reference is generated from the binary's registry, so a flag that
changed cannot ship with documentation that recommends the old one.

`cli/cmd/release` publishes to Gitea using the same SDK the binary already
vendors, which is a pleasing thing to be able to say: nothing third-party
handles the artifacts. It is a second binary rather than a `kettle` subcommand
on purpose — `kettle`'s command tree is what generates the plugin's skills, so a
verb there ships to every operator, and publishing a release is build
infrastructure. It is idempotent end to end: an existing release for the tag is
reused, an asset of the same name is replaced rather than doubled, and a retried
run converges instead of duplicating.

`make release` refuses three things, each with its own message: a dirty working
tree, a TAG that is not what `git describe` reports, and a tag the remote does
not have. A release built from uncommitted code is unreproducible and nobody
finds out until they need to reproduce it.

`kettle version` reports the stamp, the toolchain and the VCS revision. The
default is `dev`, and a hand build says so and means it — a binary out of
somebody's working tree is not a release and must not claim to be one.

AGENTS.md — plugins/

One directory per plugin, and each is self-contained: a plugin's root is its directory here, so ${CLAUDE_PLUGIN_ROOT} resolves inside it and every path a plugin uses stays relative to itself.

plugin what it is
kettle/ issues as local markdown, driven by the kettle binary in cli/. Skills, a runner subagent, two hooks
tdl/ Three Dots Labs Go conventions as an enforceable rule set. One skill, no binary, no state

Adding one

Two edits, and nothing else in the repository needs to know:

  1. a directory here holding .claude-plugin/plugin.json, plus whatever of skills/, agents/, hooks/, commands/ it needs;
  2. one entry in .claude-plugin/marketplace.json whose source is the path into this directory.

The catalog entry's name and the directory name must match, and both must match plugin.json. They are three spellings of one identity: the catalog resolves a source path, the manifest names the plugin, and the directory is what ${CLAUDE_PLUGIN_ROOT} becomes. A rename that misses one of the three installs a plugin that cannot find its own files — which is exactly what happened when tea became kettle.

The catalog's description is what somebody reads in /plugin; the manifest's is what the installed plugin reports. Keep them saying the same thing.

What a plugin may and may not do

  • A skill is prose an agent loads on demand. Its frontmatter description: is the only thing that decides whether it gets loaded at all, which makes it the one line worth tuning against real failures — and the one line no generator may write.
  • Heavy reference material goes in references/, not in the SKILL.md. The skill says when to read it.
  • A hook must fail open. Both of kettle's exit 0 on every path, including their own bugs: a plugin that breaks a user's Bash call because its documentation helper crashed is worse than no plugin.
  • State belongs to the project, never to the plugin directory. A plugin lives in a versioned cache that changes path on every update; anything written inside it is lost or invisible from the next project. This is not hypothetical — it is the bug that motivated rewriting kettle's Python scripts as a binary, and the whole reason a project carries a .kettle/ marker.

Keeping this file true

  • Scope: what a plugin directory is, how the catalog points at it, and the rules common to all of them. The table names every plugin here.
  • Update it when a plugin is added or removed or renamed, or when the catalog gains a field a plugin author has to fill in.
  • Do not describe an individual plugin's skills or design; each has its own file.
