 - **Package manager:** `pnpm` (corepack-pinned via `packageManager` in root `package.json`; Renovate bumps it often — check that field for the exact pin, don't hardcode it here; if `pnpm` is ever missing, run `corepack enable`). Workspaces via `pnpm-workspace.yaml`.
 - **Monorepo runner:** `turbo` (`turbo run build`; `test` `dependsOn: ["^build"]`, so a build is triggered as needed).
 - **Bundler:** `tsdown` per package (→ `dist/esm/`, shared options in `scripts/tsdown.config.ts`).

 - Non-trivial structural work (cross-package parity ports, manager/API redesigns, new plugin scaffolding) gets a design doc under `docs/superpowers/` before implementation: a plan at `docs/superpowers/plans/<date>-<slug>.md` and, for anything with real design decisions, a matching spec at `docs/superpowers/specs/<date>-<slug>-design.md` (e.g. `docs/superpowers/specs/2026-10-05-message-types-parity-design.md`). PR descriptions for such changes link the spec/plan instead of re-explaining the design. Check this directory for prior art before redesigning an area that already has one.
 - Activation has two paths. `plugin-scheduled-tasks` and `plugin-opentelemetry` are module-only (their `./register` is a no-op); `plugin-opentelemetry` also ships a third entrypoint, `./preload` (loaded with `--import`), which starts the OpenTelemetry SDK before the bot's own imports run — `./register` cannot do this, since it only runs after the bot has already started importing. The older plugins ship `./module` (default export: `defineModule` from `@wolfstar/kit`, optional peer) and, for those with runtime hooks, `./plugin` (default export: a `definePlugin` factory); `./register` stays the legacy class + `Client.plugins.register*Hook` path for framework v3/v5/v6. Both call the same functions in `src/hooks.ts`, so change behaviour there. The `stars` CLI never imports `<pkg>/register` itself; it only preloads the sources registered through `ctx.addPlugin`, so a user's own `import "<pkg>/register"` (or passing the `./plugin` factory to `plugins` while also importing `/register`) still double-installs the hooks. `tests/module-entries.test.ts` checks that every `src/module.ts` (except `plugin-scheduled-tasks`, excluded on purpose) is exported, built and has kit and schema as optional peers.
 - `plugin-opentelemetry` has process-level tests (`tests/preload.test.ts`: worker thread, `SIGTERM`, WebSocket handshake) that spawn Node with the preload. The CI unit job runs vitest with no build, so the test builds `src/preload.ts` itself with `tsdown` into `packages/plugin-opentelemetry/node_modules/.cache/preload-test/`. The `SIGTERM` cases are skipped on Windows (a Windows process cannot handle the signal); run them in WSL or Linux. Interaction spans are made the active span with `context.attach` (`@opentelemetry/api` 1.10), because the framework's `*Run` events do not wrap the command. `protobufjs` is denied in `allowBuilds` (its postinstall is not needed).
-- Module config keys: every `defineModule` sets `meta.configKey`, so a project writes the options under that top-level key of `stars.config` instead of the `[specifier, options]` tuple (the tuple is merged over the key and wins). Needs `@wolfstar/kit` `^0.2.0` (the peer and dev range of every package with a `src/module.ts`), and each `module.ts` augments `StarsConfig` from `@wolfstar/schema` (an optional peer and devDependency) to type the key. Keys: `plugin-api` `api`, `plugin-broker` `broker`, `plugin-cache` `cache`, `plugin-gateway` `gateway`, `plugin-i18next` `i18n`, `plugin-logger` `logger`, `plugin-opentelemetry` `opentelemetry`, `plugin-scheduled-tasks` `scheduledTasks`, `plugin-sharder` `sharder`, `plugin-subcommands-advanced` `subcommandsAdvanced`; `cache`, `gateway`, `sharder` and `subcommandsAdvanced` take no options yet and only reserve the name. A key must be unique and not a built-in key (`BUILT_IN_CONFIG_KEYS` of `@wolfstar/schema`); renaming one is a breaking change. `tests/module-config-keys.test.ts` runs every module through kit's `setupModules`. What sits under a key is written into the build, so it must be JSON.
