## Background
Plugin package discovery / explicit enablement / Tool registration / WASM Tool runtime / permission grants まで実装されたため、次に必要なのは「なぜ Plugin が見えない / 有効化されない / 実行できないのか」を headless に確認できる read-only inspection surface である。
Panel や TUI diagnostic に出す前に、CLI で deterministic に確認できる `yoi plugin list` / `yoi plugin show <ref>` を追加する。この CLI は Plugin code を実行せず、package discovery、manifest parse、enablement resolution、grant validation、static diagnostics を表示するだけにする。
目的は、Plugin の多段 failure point を human / JSON の両方で確認できるようにすること。
```text
package discovered?
manifest valid?
api version compatible?
explicitly enabled?
digest/version/source match?
requested permission granted?
tool schema valid?
runtime config present?
```
## Requirements
- Top-level product CLI に read-only Plugin inspection command を追加する。
- `yoi plugin list`
- `yoi plugin show <ref>`
- `--json` output を最初から提供する。
- `yoi plugin list --json`
- `yoi plugin show <ref> --json`
- Human-readable output は JSON 用 typed report の thin formatting にする。
- Workspace / Profile resolution は通常起動に近い意味にする。
- default は current workspace。
- 既存 CLI 方針に合わせて `--workspace <path>` を扱う。
- Profile 指定が必要なら既存 Profile selector と整合する option を使う。
- Plugin code を実行しない。
- WASM module を実行しない。
- Tool call を発生させない。
- Hook / Service / Ingress を起動しない。
- Read-only とする。
- install / update / enable / disable / trust / sign / run は non-goal。
- Plugin package / config / Ticket / memory / Pod state を変更しない。
- Inspection report は typed data として実装する。
- future Panel diagnostic / tests / agent-readable output で再利用できる形にする。
- `list` は package/ref 単位の overview を出す。
- ref
- source
- package path (human output では必要に応じて短縮)
- version
- api version
- digest
- status
- enabled surfaces
- diagnostic count / summary
- `show <ref>` は詳細を出す。
- manifest metadata
- source-qualified identity
- package path
- digest
- version / api version
- runtime kind/config summary
- enabled surfaces
- Tool definitions and registration eligibility
- requested permissions
- granted permissions
- effective grants / denied grants
- diagnostics
- Status vocabulary を明確にする。
- `active`: enabled and statically valid for at least one surface/tool.
- `disabled`: discovered but not explicitly enabled.
- `missing`: enablement refers to a package that is not discovered.
- `rejected`: invalid manifest / incompatible api / digest mismatch / grant mismatch / invalid schema etc.
- `partial`: package is usable but some surfaces/tools are rejected.
- Diagnostics は bounded / safe にする。
- secret-like values / auth / file contents を出さない。
- path は必要最小限。JSON では absolute path が必要なら workspace/user store source と一緒に出す。
- denial / parse / digest / grant mismatch reasons を区別できる。
- Ambiguous unqualified ref は fail closed し、`show` で diagnostic を返す。
- JSON schema は stable typed structure として test で固定する。
## Example human output
`yoi plugin list`:
```text
REF SOURCE VERSION STATUS SURFACES DIGEST
project:example.echo project 0.1.0 active tool sha256:...
project:broken project - rejected - -
user:fetch user 0.2.1 disabled tool sha256:...
```
`yoi plugin show project:example.echo`:
```text
Plugin: project:example.echo
Source: project
Package: .yoi/plugins/example.echo.yoi-plugin
Version: 0.1.0
API: yoi-plugin-1
Digest: sha256:...
Status: active
Enabled surfaces:
- tool
Tools:
- example_echo
status: registered
schema: valid
external_write: false
Permissions:
Requested:
- surfaces.tool
- tool:example_echo
Granted:
- surfaces.tool
- tool:example_echo
Diagnostics:
- none
```
## Acceptance criteria
- `yoi plugin list` prints a bounded human-readable overview without executing Plugin code.
- `yoi plugin show <ref>` prints detailed static inspection for a Plugin ref without executing Plugin code.
- `--json` output is available for both commands and uses a stable typed structure.
- Valid enabled Plugin appears as `active`.
- Discovered but not enabled Plugin appears as `disabled`.
- Enabled but missing package appears as `missing`.
- Invalid manifest / incompatible api version appears as `rejected` with diagnostic.
- Digest / version / source mismatch appears as diagnostic.
- Grant denial / missing requested permission appears as diagnostic.
- Partial tool/surface rejection can be represented without marking the whole package as fully active.
- Ambiguous unqualified id fails closed with diagnostic.
- Plugin code / WASM / Tool execution is not triggered by list/show.
- Tests cover:
- list human output for active / disabled / rejected / missing packages
- show human output for active package with Tool surface and grants
- JSON list structure
- JSON show structure
- invalid manifest diagnostic
- digest mismatch diagnostic
- missing grant diagnostic
- ambiguous ref diagnostic
- no runtime execution from inspection path
- Validation: focused CLI/plugin inspection tests, relevant `cargo check` / `cargo test`, `cargo fmt --check`, `git diff --check`, and `nix build .#yoi` because product CLI / packaging surface changes.
## Non-goals
- Plugin install / update / remove.
- Enable / disable mutation.
- Trust / signature / registry implementation.
- Plugin code execution.
- WASM validation beyond static runtime config/manifest inspection.
- `https` host API implementation.
- `fs` host API implementation.
- Service / Ingress startup.
- Panel/TUI Plugin diagnostics UI.
## Implementation notes
- Product CLI ownership stays in the `yoi` crate.
- Avoid embedding resolver logic directly in display formatting; build a typed inspection report first.
- Reuse existing Plugin resolver / diagnostics where possible.
- Keep CLI output deterministic and suitable for tests.
- Do not introduce user-facing terminology `contribution category`; use Plugin runtime / surface / host API / grants.
