# Working in tizen-agent-skills

This repository is Samsung's open-source collection of Tizen development
plugins for AI coding agents. Each top-level directory is one independently
versioned plugin (`tizen-sdk-skills/`, `tizen-action-skills/`, …).

Start with [README.md](README.md) and [CONTRIBUTING.md](CONTRIBUTING.md). For
detailed authoring and review instructions, read each plugin's own
`CONTRIBUTING.md` (for example
[tizen-sdk-skills/CONTRIBUTING.md](tizen-sdk-skills/CONTRIBUTING.md)).

## Essential rules

### Plugin structure

- `common/` is the single source of truth for every plugin — skills, agents,
  hooks, `lib/`, `scripts/`, `setup/`. The host wrapper directories
  (`claude/`, `cline/`, `codex/`, `gemini/`) hold thin adapters only; never
  duplicate logic into them.
- Do not edit the mirrored copies under `~/.claude`, `~/.cline`, `~/.codex`
  or `~/.gemini`; re-run the plugin's setup script instead.
- After changing a runner-lookup snippet or `HOST_DOT_DIRS` in
  `common/lib/core/plugin-cache.js`, run
  `node scripts/rewrite-runner-snippets.js` and then `--check`.

### Versioning

- **Repository release version** — root `package.json` `version`, tracked in
  root `CHANGELOG.md`. Tags follow `tizen-agent-skills-vX.Y.Z`.
- **Plugin versions are independent** — each plugin's `package.json` and
  `common/.claude-plugin/plugin.json` carry the plugin's own version
  (for example `tizen-sdk-skills` is at 1.4.x, `tizen-action-skills` at 1.0.x).
  Bump them independently of the release version.
- Keep `plugin.json` `version` and `package.json` `version` in sync within a
  plugin.
- `marketplace.json` `metadata.version` is the catalog-structure version; bump
  it only when the catalog itself changes, not on every plugin version bump.

### Adding a new plugin

Follow the checklist in
[CONTRIBUTING.md → Adding a new plugin](CONTRIBUTING.md#adding-a-new-plugin).
A new plugin must register in `marketplace.json`, `README.md`/`README.ko.md`
plugin table (between `<!-- plugins:start -->` / `<!-- plugins:end -->`),
`llms.txt`, `CONTRIBUTING.md`, `.github/CODEOWNERS`, and `release.yml`.

### Documentation

- Write English first; provide a Korean mirror (`README.ko.md`,
  `CONTRIBUTING.ko.md`, `CHANGELOG.ko.md`).
- Give each hand-written document one H1 as its first content heading.
- Use lowercase kebab-case for new file and directory names.
- Keep `llms.txt` updated when adding significant new documentation.

### Security

- **Never commit** internal hostnames, private IP addresses, personal home
  paths, credentials, certificates (other than the documented throwaway test
  fixture) or captured session logs that contain them. The pull request
  template has a checklist item for this.

### Commits and pull requests

- Use [Conventional Commits](https://www.conventionalcommits.org/) with the
  plugin name as scope, for example `fix(tizen-sdk-skills): ...`,
  `docs(tizen-action-skills): ...`.
- Keep pull requests focused on one plugin directory; CI workflows are scoped
  per project (`.github/workflows/*.yml` filter on `<project>/**`).
- Open an issue before starting large changes so the approach can be agreed
  first.

## Validating a change

### tizen-sdk-skills

```bash
# Lint and format (repo-wide)
pnpm install --frozen-lockfile && pnpm run lint && pnpm run format:check

# Unit tests
node common/lib/tests/run-all.js
bash common/hooks/hooks.test.sh

# Runner snippets and SPDX headers in sync
node scripts/rewrite-runner-snippets.js --check
node scripts/add-spdx-headers.js --check

# Rules on the files this change touches (authoring; add --format jsonl when reviewing,
# CI uses --format github to annotate the pull request's Files changed tab)
node scripts/check-pr.js --base origin/main

# Standalone CLI compiles
cd tizen-cli && pnpm install --frozen-lockfile && pnpm exec tsc --noEmit && pnpm run build

# Test-case schema lint (no SDK or device required)
cd tests && npm ci && node runner.mjs --dry-run
npm run lint        # TC schema dry-run + doc-stats + runner helper tests
npm run test:safe   # safe-tier TCs, no SDK or device required
```

`pnpm` is used at the plugin root and in `tizen-cli/`; `npm` is used in
`tests/`. Test tiers (safe / mutating / device) are defined in
[tizen-sdk-skills/tests/README.md](tizen-sdk-skills/tests/README.md#tier-classification).
Record which tiers you ran in the PR's Testing section.

`check-pr.js` reports each finding with a rule ID. `ERROR` blocks the pull
request; fix every one. `WARN` does not block, but each one must be fixed or
explained in the pull request description before approval. A run always ends
with a summary line such as `check-pr: 0 ERROR, 0 WARN (12 files, 0.05s)`; if
nothing is printed, the check did not run, so check the `--base` revision.

The check cannot judge these, so its silence is not approval:

- logic duplicated into a host wrapper instead of `common/`;
- a spawned process whose exit code is not checked;
- a `.sh` change without the matching `.ps1` change (or the reverse);
- personal information inside an added image or screenshot.

### tizen-action-skills

No build step or test suite yet. Verify that `plugin.json` and `package.json`
versions are in sync and that the skill README renders correctly.
