[codex] Support plugin manifest path lists (#28790)
## Summary
Allow plugin manifests to declare `skills` as either a single path
string or an array of path strings in the core plugin loader.
## Why
Some plugin packages need to expose skills from more than one directory.
Before this change, `plugin.json` only accepted a single string for
`skills`, so manifests like this were ignored as an invalid `skills`
shape:
```json
{
"skills": ["./skills/abc", "./skills/edk"]
}
```
This keeps the existing single-string form working while adding support
for the list form. The final scope is intentionally limited to the core
plugin manifest/load path for `skills`; `apps`, file-backed
`mcpServers`, and the bundled plugin-creator assets are unchanged in
this PR.
## What changed
- Parse `skills` as either a string or an array of strings in
`plugin.json`.
- Store resolved skill paths as a list in `PluginManifestPaths`.
- Load manifest-declared skill roots in addition to the default
`./skills` root.
- Deduplicate exact duplicate skill roots before loading.
- Rely on existing skill-loader dedupe by canonical `SKILL.md` path for
overlapping roots such as `./skills` plus `./skills/abc`.
- Update plugin manifest tests to cover:
- single string `skills`
- list of string `skills`
- duplicate skill roots
- `./skills` as a manifest path
- explicit child roots like `./skills/abc` and `./skills/edk`
- overlapping-root dedupe
## Validation
- `just test -p codex-plugin`
- `just test -p codex-core-plugins`
- `just test -p codex-mcp-extension`
- `git diff --check`

[codex] Support object-valued plugin MCP manifests (#28580)
## Summary
This fixes plugin manifest parsing for MCP servers declared as an object
directly in `plugin.json`.
Before this change, Codex modeled `mcpServers` as only a string path,
for example:
```json
{
"name": "counter-sample",
"version": "1.1.1",
"mcpServers": "./.mcp.json"
}
```
Some migrated plugins instead provide the server map directly in the
manifest:
```json
{
"name": "counter-sample",
"version": "1.1.1",
"description": "Plugin that declares MCP servers in the manifest",
"mcpServers": {
"counter": {
"type": "http",
"url": "https://sample.example/counter/mcp"
}
}
}
```
That object form previously failed during install/load with an error
like:
```text
failed to parse plugin manifest: invalid type: map, expected a string
```
## What changed
- Add a manifest representation for `mcpServers` as either
`Path(Resource)` or `Object(map)`.
- Parse `plugin.json` `mcpServers` as either a string path or an object.
- Route object-valued MCP server maps through the existing plugin MCP
config parser instead of adding a second parser.
- Apply existing per-plugin MCP server policy to object-valued MCP
servers the same way as file-backed MCP servers.
- Include object-valued MCP server names in plugin telemetry/capability
metadata.
- Support object-valued MCP config for executor plugins without
requiring a `.mcp.json` filesystem read.
- Update the bundled plugin-creator validator and `plugin-json-spec.md`
so generated-plugin validation accepts the same object-valued shape.
## Compatibility
Existing plugin manifests that use `"mcpServers": "./.mcp.json"`
continue to work. Plugins can now also use the object shape shown above.
## Tests
Added coverage for the new manifest attribute shape at the install,
normal load, telemetry, and executor-provider layers:
- `install_accepts_manifest_mcp_server_objects`
- `load_plugins_loads_manifest_mcp_server_objects`
- `plugin_telemetry_metadata_uses_manifest_mcp_server_objects`
- `reads_manifest_object_config_without_executor_file_system_access`
Also smoke-tested the plugin-creator validator against both supported
forms:
- `mcpServers` as a direct object in `plugin.json`
- `mcpServers` as `"./.mcp.json"` with a companion `.mcp.json`
## Validation
- `just test -p codex-plugin`
- `just test -p codex-core-plugins`
- `just test -p codex-mcp-extension`
- `just bazel-lock-update`
- `just bazel-lock-check`
- `just fmt`
- `git diff --check`
- Focused rename/object-form rerun: `just test -p codex-core-plugins
manager::tests::load_plugins_loads_manifest_mcp_server_objects

- Focused executor rerun: `just test -p codex-mcp-extension

Add executor-owned plugin resolution (#27692)
## Why
CCA can select a capability root that lives in an executor environment,
but
Codex only had a host-filesystem plugin loader. Before selected executor
plugins can contribute MCP servers, we need a small package boundary
that can
answer:
> Does this selected root contain a plugin, and if so, what does its
manifest
> declare?
The answer must come from the selected environment's filesystem. A
failed
executor lookup must never fall back to the orchestrator filesystem.
## What this changes
This PR introduces:
```rust
PluginProvider::resolve(root)
-> Result<Option<ResolvedPlugin>, Error>
```
`ExecutorPluginProvider` resolves one `SelectedCapabilityRoot` through
its
exact `environment_id`. It checks the recognized manifest locations,
reads the
manifest through that environment's `ExecutorFileSystem`, and returns an
inert
`ResolvedPlugin` containing:
- the opaque selected-root ID;
- the environment-bound plugin root;
- the authority-bound manifest resource;
- parsed metadata and authority-bound component locators.
Descriptor construction rejects manifest or component paths outside the
selected package root, so consumers cannot accidentally lose the package
boundary when they receive a resolved plugin.
If the root has no plugin manifest, resolution returns `None`, allowing
the
caller to treat it as a standalone capability such as a skill.
```text
selected root: repo -> env-1:/workspace/repo
|
| env-1 filesystem only
v
.codex-plugin/plugin.json
|
v
ResolvedPlugin { authority, root, manifest }
```
The existing host loader and the new executor provider now share the
same
manifest parser. Existing `codex-core-plugins::manifest` type paths
remain
available through re-exports, so host behavior and callers are
unchanged.
## Scope
This is intentionally a non-user-visible package-resolution PR. It does
not:
- parse or register plugin MCP server configurations;
- activate skills, connectors, hooks, or MCP servers;
- change app-server wiring;
- introduce host fallback, caching, or lifecycle behavior.
#27670 has merged, and this PR is now based directly on `main`. Together
with
the resolved MCP catalog from #27634, it establishes the inputs needed
for the
executor stdio MCP vertical without changing the existing MCP runtime.
## Follow-up
The next PR will consume `ResolvedPlugin`, read its declared/default MCP
config
through the same executor filesystem, bind supported stdio servers to
that
environment, and feed those registrations into the resolved MCP catalog.
An
app-server E2E will prove that selecting an executor plugin exposes and
invokes
its tool on the owning executor.
Resume/fork semantics, dynamic environment replacement, and non-stdio
placement remain separate lifecycle decisions.
## Validation
- `just fmt`
- `cargo check --tests -p codex-plugin -p codex-core-plugins`
- `just bazel-lock-check`
- `git diff --check`
Test targets were compiled but not executed locally; CI will run the
test and
Clippy suites.
