Expose discoverability and full share principals in share context, carry
roles through save/updateTargets, hydrate local shared plugin reads, and
keep share URLs only under plugin.shareContext.
Requires discoverability on plugin/share/updateTargets so the server can
manage workspace link access consistently, including auto-adding the
workspace principal for UNLISTED.
Also rejects LISTED on share creation and blocks client-supplied
workspace principals while preserving response parsing for LISTED.
Supersedes the abandoned #19859, rebuilt on latest `main`.
# Why
PR #19705 adds discovery for hooks bundled with plugins, but `/plugins`
still only shows skills, apps, and MCP servers. This follow-up makes
bundled hooks visible in the same plugin detail view so users can
inspect the full plugin surface in one place.
We also need `PluginHookSummary` to populate Plugin Hooks in the app;
`hooks/list` is not enough there because plugin detail needs to show
hooks for disabled plugins too.
# What
- extend `plugin/read` with `PluginHookSummary` entries for bundled
hooks
- summarize plugin hooks while loading plugin details
- render a `Hooks` row in the `/plugins` detail popup

Adds marketplaceKinds to plugin/list for local, workspace-directory, and
shared-with-me; omitted params keep default local plus gated global
behavior, while explicit kinds are exact.
Exposes shareContext on plugin summaries from local share mappings and
remote workspace/shared responses, including remotePluginId and nullable
creator metadata.
Adds shared-with-me listing through /ps/plugins/workspace/shared,
renames the workspace remote namespace to workspace-directory, and keeps
direct remote read/share/install/update/delete paths gated by plugins
rather than remote_plugin.
# Overview
MCP refreshes were rebuilding active threads from fresh disk-backed
config only, which dropped thread-start session overlays such as
app-injected MCP servers. This keeps refreshes current with disk config
while preserving the thread-local config that only the active thread
knows about.
# Changes
- Rebuild refreshed config per active thread using that thread's current
`cwd`, rather than fanning out one app-server config to every thread.
- Preserve each thread's `SessionFlags` layer while replacing reloadable
config layers with freshly loaded config, then derive the MCP refresh
payload from the rebuilt result.
- Move MCP refresh orchestration into app-server so manual refreshes
fail loudly while background refreshes remain best-effort, and route
plugin-triggered refreshes through the same per-thread reload path.
- Add regression coverage for session overlays, fresh project config,
plugin-derived MCP config, current requirements, and strict vs
best-effort refresh behavior.
# Verification
- Passed focused Rust coverage for the thread-config rebuild behavior
and deferred MCP refresh flow, plus `cargo test -p codex-app-server
--lib`.
- Verified end to end in the Codex dev app against the locally built
CLI: registered an MCP via thread config, verified that it could be used
successfully before refresh, manually triggered MCP refresh, and
verified that it continued to be available afterward.
Extends `plugin/share/save` to accept optional discoverability and
shareTargets while uploading plugin contents, and adds
`plugin/share/updateTargets` for share-only target updates without
re-uploading.
## Summary
- Add plugin manifest keywords to core plugin marketplace/detail models
- Expose keywords on app-server v2 PluginSummary and generated
schema/types
- Populate keywords in plugin/list and plugin/read responses for local
plugins

## Why
App-server had repeated hand-built JSON-RPC error objects for standard
error shapes. Using the shared helpers keeps the common
`invalid_request`, `invalid_params`, and `internal_error` construction
in one place and reduces the chance of new call sites drifting from the
common error payload shape.
## What changed
- Replaced manual standard JSON-RPC error object creation with
`internal_error(...)`, `invalid_request(...)`, and `invalid_params(...)`
across app-server request processors and runtime paths.
- Removed local duplicate helper definitions from search and review
request handling.
- Preserved existing structured `data` payloads by creating the shared
helper error first and then attaching the existing metadata.
- Left custom non-standard errors and raw error-code assertions intact.
## Validation
- `cargo test -p codex-app-server`
## Summary
Remove the hardcoded remote plugin ID prefix allow-list from app-server
uninstall routing. IDs that do not parse as local `plugin@marketplace`
IDs now flow through the remote uninstall path, where the existing
remote ID safety validation still rejects empty IDs, spaces, slashes,
and other unsafe characters before URL/cache use.
## Why
Plugin-service owns the backend remote plugin ID contract. Codex should
not require remote IDs to start with the local hardcoded prefixes
`plugins~`, `plugins_`, `app_`, `asdk_app_`, or `connector_`, because
newer backend ID families could otherwise be rejected before
plugin-service sees the request.
## Validation

- `just fix -p codex-app-server`
- `git diff --check`
## Why
The app-server request path had grown around a large
`CodexMessageProcessor` plus separate API wrapper/helper modules. That
made the dependency graph hard to see and forced unrelated request
families to share broad processor state.
This PR makes the split mechanical and command-prefix oriented so
request families own only the dependencies they use.
## What changed
- Replaced `CodexMessageProcessor` with command-prefix request
processors under `app-server/src/request_processors/`.
- Removed the old config, device-key, external-agent-config, and fs API
wrapper files by moving their API handling into processors.
- Split apps, plugins, marketplace, catalog, account, MCP, command exec,
fs, git, feedback, thread, turn, thread goals, and Windows sandbox
handling into dedicated processors.
- Kept shared lifecycle, summary conversion, token usage replay, and
shared error mapping only where multiple processors use them; single-use
helpers were inlined into their owning processor.
- Removed the fallback processor path and moved processor tests to
`_tests` files.
