`@deepseek-ai/dsh-skill` is the pure provider registry (`ctx.skills`), `@deepseek-ai/dsh-skill-local` is the shipped local filesystem provider, and `@deepseek-ai/dsh-tool-skill` owns the session-prefix catalog and model-facing loader tool. `dsh-agent-core` loads the registry, local provider, and consumer by default so stdio and ACP apps get the same behavior while embedded or remote providers contribute skills without changing the registry or consumer. Its `skills` config forwards `registry`, `local`, and `tool` branches to those owners.
Provider plugins register synchronously during `apply()`. Provider catalogs return ranked candidates from awaited `list()` calls, where remote providers perform initialization, authentication, and discovery while honoring the lookup abort signal. The registry validates each candidate, resolves same-name skills first-wins by rank, provider registration order, and provider-local order, then sorts summaries by skill name for deterministic consumers. It caches only completed catalog snapshots and retries when a provider/runtime revision changes during discovery, so an unload cannot freeze a stale, unresolvable skill into a session prefix. Runtime `ctx.skills.register(...)` remains a convenience for embedded in-process skills and uses project-over-user priority; `runtime` is reserved as the registry-owned provider name.

The user `.dsh/skills` scan skips `.system` so a system-owned directory is not treated as normal user content.

## Decision
The `stdio-chat` module now lives inside `dsh-stdio-agent` with its runtime seam. Per-file tests cover EOF, rendering, disposal, and piped-versus-TTY behavior without replacing process globals. It retains the named Cordis plugin export shape consumed by the app; an `unwrapExports` assertion and keyless Loader smokes guard both the package and composed entry paths.
The helper lives in `@deepseek-ai/dsh-stdio` as the terminal-channel plugin (`packages/ui/stdio/src/index.ts`): `createStdioChat`, its `StdioRuntime` test seam, and its unit tests (`packages/ui/stdio/tests/stdio.spec.ts`, `readline.spec.ts`) moved with it, so EOF handling, rendering, disposal, and piped-vs-TTY behavior stay unit-covered under the per-file coverage gate without hijacking process globals. The module keeps the named `name`/`inject`/`Config`/`apply` export shape — the contract the app's `ctx.plugin(uiStdio, …)` mount consumes — and the keyless Loader-path smokes in `examples/echo-agent` and `examples/coding-agent` keep proving the composed tree boots through the real Loader (the stdio package's plugin-shape unit suite pins the explicit `unwrapExports` assertion, since a bundle without `inject` would boot past a stray default rather than crash).
The `packages/support/ui-stdio` package is gone: manifest, tsconfig references, module-graph rows, and README rows deleted; the doc comments that named the package (the example e2e module docs, `packages/README.md`, the support and todo READMEs, [the ui group README](../../../../packages/ui/README.md)) describe the in-package module.

# RFC: Drop unconsumed skill provider events
Status: proposed
Status: implemented
## Problem
@@ -10,23 +10,18 @@ Skill discovery reads the current provider map on demand, provider registration
`tools/change` and `system-prompt/change` are explicitly outside this proposal. Existing simplification decisions retain them as intentional observation points for live tool and prompt UIs, and self-referential mounted plugins already use `tools/change`. This proposal also leaves `subagent/provider-added`/`removed` unchanged because `tool-subagent` has a production lifecycle consumer.
## Proposal
## Decision
Delete the two skill-provider declarations and every emit path, rollback-order branch, test, and generated catalog/matrix row that exists only for them. Remove the corresponding skill-registry README/JSDoc contract. Where tests used an event to observe cleanup, assert provider lookup or collected output instead.
The skill registry declares and emits no provider-membership events. Provider registration and disposal remain direct effect-owned state changes that synchronously invalidate completed catalogs; lookup and discovery read the current provider map on demand. Tests observe cleanup through provider lookup and collected output rather than lifecycle notifications.
Amend the skill-system RFC and package documentation so provider registration is described as direct effect-owned state with cache invalidation, not as a lifecycle notification contract.
The generated event catalog, API catalog, and producer/consumer matrix omit the deleted notifications. The skill-system RFC and package documentation describe registration through its direct effect-owned state and cache-invalidation contract.
## Alternatives considered
**Keep skill-provider notifications for future plugins.** A third-party plugin could observe provider availability, but direct provider registration and on-demand lookup are the extension contract; no current consumer needs a push signal. If a future sibling-load race appears, it can introduce a notification with the identity and readiness semantics that consumer requires, as the subagent registry did.
## Acceptance criteria
## Consequences
- The generated event matrix contains no row for `skill/provider-added` or `skill/provider-removed`.
- Skill discovery, direct runtime registration, provider effect rollback/disposal, cache invalidation, and registry lookup cleanup behave unchanged; listener-triggered rollback disappears with the events.
- `tools/change`, `system-prompt/change`, and the real subagent provider lifecycle consumer remain documented and covered.
- Typecheck, coverage, snapshots, doc-sync, module-graph verification, build, and hygiene pass.
The generated event matrix contains no row for `skill/provider-added` or `skill/provider-removed`. Skill discovery, direct runtime registration, provider effect rollback/disposal, cache invalidation, and registry lookup cleanup remain; listener-triggered rollback disappears with the events. `tools/change`, `system-prompt/change`, and the consumed subagent provider lifecycle events are unchanged.
## Risks
This removes pre-release skill-provider observation points while retaining both ways third-party plugins contribute skills: direct runtime registration and provider registration. A future consumer that needs live provider availability must add a purpose-built notification rather than relying on these generic events.
Pre-release consumers lose skill-provider observation points while retaining both ways to contribute skills: direct runtime registration and provider registration. A future consumer that needs live provider availability must add a purpose-built notification with the identity and readiness semantics it actually requires.
