## What changed
- Give `PluginsManager` a shared `AuthManager` instead of a separately mutable authentication-mode snapshot.
- Read the current authentication mode and credentials from that shared manager for plugin discovery, startup tasks, CLI commands, MCP setup, and external-agent migration.
- Update test helpers and coverage to exercise plugin projections and curated marketplace selection as authentication changes.

## Why
Concurrent Guardian samples can finish out of order, allowing an older sample to
replace the thread's newer in-memory security risk score.
## What changed
- Record when each `SecurityRiskScore` sample starts while preserving compatibility
with records that have no timestamp.
- Add `ExtensionData::insert_if` so checking and replacing a typed attachment happen
under the same lock.
- Update Guardian V2 to replace the thread's risk score only when the completed sample
is newer than the stored one.
## Testing
- Verify concurrent conditional inserts retain the newest value.
- Verify Guardian-generated risk scores include a sampling timestamp.
GitOrigin-RevId: 6543a4e5497da4c623331050789e91613f931c4b
## What changed
- Replace the single `category` and `score` fields in `SecurityRiskScore` with a
deterministic map of category names to scores.
- Validate the full Guardian V2 classifier response before storing it as one
thread extension value and, for non-ephemeral threads, one rollout item.
- Cover serialization and rollout loading with snapshots containing multiple
score categories.
GitOrigin-RevId: 24525de691f96bd34ccfe04acab2f01aca309837
## Why
The model provider does not reliably identify which curated plugin catalog is
available. ChatGPT authentication can be used with a custom provider, while an
unauthenticated session should use the API-compatible catalog regardless of its
provider.
## What changed
- Select the ChatGPT curated catalog only for authentication modes that use the
Codex backend; use the API curated catalog for API-key and unauthenticated
sessions.
- Initialize standalone plugin managers with the current authentication mode
across CLI, app-server, MCP, and external-agent migration paths.
- Preserve authentication mode while detecting and importing migrated plugins.
## Testing
- Cover catalog and skill routing across ChatGPT, API-key, unauthenticated,
Bedrock, and custom-provider configurations.
- Verify authenticated plugin migration uses the ChatGPT curated marketplace.
GitOrigin-RevId: 660a339ee8891c33aad961078d3a979242a6a166
## What changed
- Add a `SecurityRiskScore` rollout item containing a category and numeric score.
- Persist the item in both thread history modes while excluding it from model context, user-visible thread history, search text, forks, and reconstructed conversation history.
- Re-export the score type from the extension API.
## Testing
- Cover serialization, persistence and loading, thread history projection, session reconstruction, append planning, and memory filtering.
GitOrigin-RevId: 1926fe366aeaa75052708a6da589f45a38eefb52
## What changed
- Wrap response items with optional harness-owned metadata while keeping the persisted response payload shape backward compatible.
- Store compacted-history metadata in an aligned sidecar and reject malformed sidecars.
- Carry metadata through history normalization, compaction, resume, fork, truncation, migration, and rollout recording without sending it to model providers.
## Testing
- Cover legacy rollout compatibility, metadata serialization and validation, compaction retention, and resume/fork reconstruction.
GitOrigin-RevId: 17a6127c9048ff984cb4df4d97c0751a38c29f5f
## What changed
- Add `codex-history` for model-history and persisted-rollout domain types, including `RolloutItem`, `RolloutLine`, `CompactedItem`, and initial/resumed history state.
- Re-export the persisted types from `codex-rollout` and update consumers to use the new crate boundary instead of `codex-protocol`.
- Preserve existing rollout serialization, including legacy numeric compacted-window IDs.
## Testing
- Add `codex-history` tests for rollout JSON round trips, compacted-history compatibility, persisted history modes, and multi-agent version selection.
GitOrigin-RevId: 944daa9297ddd231d3aebbdcb05fff4adf8b4e1b
## Why
Resolving the working directory encoded in a Cursor project name could recursively scan large directory trees.
## What changed
- Probe a bounded set of path candidates using common filename separators instead of walking the directory tree.
- Stop after 128 probes and reject ambiguous matches or unsafe encoded components.
- Parse Windows drive prefixes separately from the encoded path.
## Testing
Added coverage for common separators, ambiguous leaf and ancestor paths, and Windows drive prefixes.
GitOrigin-RevId: 34b2a2bbe2d302fac3d2614a5e36dd3fa20cf2e5
## What changed
- Inject the host skill loader into `PluginsManager` so plugin discovery and agent turns use the same loading and product-policy behavior.
- Share plugin skill snapshots across those paths, preserving a consistent view of skills across workspaces.
- Apply migrated-command precedence after product filtering, allowing an eligible migrated command to replace a filtered native skill with the same name.
## Testing
- Add coverage for product-restricted plugin skills, native-versus-migrated command precedence, and the skills exposed to agent turns.
GitOrigin-RevId: f5ef0d0766ebeeb30d73ffaf044d003c2906ea4d
## Why
Session IDs are derived from file stems and can repeat across projects. Keying
connector attribution only by session ID can therefore assign one session's
connectors to another session during a batched migration.
## What changed
- Preserve connector candidates by canonical source path until each imported
session is annotated, then aggregate them for detection summaries.
- Resolve project-backed MCP tool calls from both `CallMcpTool` server IDs and
`mcpDetails.serverName`, while requiring a match in project metadata.
## Testing
Add coverage for duplicate session stems, per-source connector results, and
both supported project-backed MCP tool-call formats.
GitOrigin-RevId: 10563d47c29673c07daa83be5f4e1a256740b901
## Why
Cursor stores projectless chats under the reserved `empty-window` project, and
their transcripts may not contain embedded working-directory metadata.
## What changed
- Resolve `empty-window` sessions to the parent of the Cursor home directory,
including when that home is configured as a relative path.
- Record each created or appended session's working directory in its import
success result instead of inheriting the migration item's directory.
## Testing
- Cover projectless Cursor transcripts without embedded metadata.
- Cover working-directory resolution from a relative Cursor home.
GitOrigin-RevId: 21cc7ea6acab1ed80cc4016a881e07eca3d0abbd
## What changed
- Return connector candidates found in detected external agent sessions, aggregating session counts by connector name.
- Resolve connector names from both cached plugin manifests and project MCP server metadata.
- Persist detected connector clues in the session import ledger and merge them into completed imports without case-insensitive duplicates.
## Testing
- Add coverage for project MCP metadata detection and for accumulating detected and imported connector candidates.
GitOrigin-RevId: 97a7dfe4a61599686b2222cddd9595acec8b4501
## What changed
- Discover and import home-level Cursor skills from both `skills` and
`skills-cursor`.
- Keep repository-level Cursor migration scoped to `skills`.
- Deduplicate skill names when reporting migration candidates from multiple
source directories.
## Testing
- Add coverage for detecting and importing user and Cursor-managed skills.
- Verify repository detection continues to use the `skills` directory.
GitOrigin-RevId: 7b5e96a0d9c5ca14c61230e336728f2e4930a3b0
## Why
External agent session files can gain messages after their initial import. Re-importing those files should extend the existing Codex thread instead of creating a duplicate.
## What changed
- Map a changed source session back to its uniquely imported thread and append only the missing transcript suffix.
- Update the import ledger after verifying that the source and destination transcripts match.
- Defer the update when the target is active, archived, ambiguous, diverged, or otherwise unsafe to modify.
## Testing
Added unit and app-server coverage for suffix planning, ledger checkpointing, concurrent updates, and unsafe targets that must be deferred.
GitOrigin-RevId: 3d9e71cd66e8b31cf5128e8869063868bfb3eb05
## What changed
- Add session connector detection to `ExternalAgentConfigService` for Claude and Cursor migrations.
- Resolve Claude connector attributions through session manifests and map Cursor `CallMcpTool` server IDs through cached plugin metadata.
- Return deduplicated connector candidates with their session counts and detection sources, and expose the new result types from the migration crate.
## Testing
- Cover Claude connector resolution by server name and UUID.
- Cover Cursor connector detection and per-session counting from MCP tool calls.
GitOrigin-RevId: 772bfe949bdc734b385a6e06f6a4b1d35b4cf210
## Why
External-agent migration treated symlinked empty text targets as overwritable files. Writing migrated configuration through such a target could modify a file outside the repository.
## What changed
- Use symlink metadata when checking whether a migration target is missing or empty, so only regular files are considered overwritable.
- Preserve symlinked `AGENTS.md` and `.codex/hooks.json` targets during both detection and import.
## Testing
Added Unix regression coverage for existing and dangling symlink targets for both guidance and hooks migration.
See https://github.com/openai/codex/pull/26021.
GitOrigin-RevId: 13c78e7458d1c02abdb22b38ba88ed66bb5a154b
## What changed
- Preserve the original title when importing an external-agent session and return it with successful session entries from `externalAgentConfig/import/readHistories`.
- Add dedicated history-record success types so externally completed imports can optionally supply a session title without changing the live import result type.
## Testing
- Verify imported session titles are returned by the app server and persisted when session import ledger entries are created or refreshed.
GitOrigin-RevId: e896688a5763c238f1e1dc8b4672a7aa7bc1ed4c
## Why
Imported session attribution can identify an MCP server by its configured name
instead of the UUID stored in the session manifest.
## What changed
Match attributed MCP servers against normalized manifest names without regard to
case, while retaining UUID matching.
## Testing
Add focused coverage for both name- and UUID-based attribution.
GitOrigin-RevId: 827443f9e7f14028e17b5c5775ca372bfe2e217e
## Why
Cursor session messages can place `<cursor_commands>` and `<timestamp>` context
before the actual `<user_query>`. Treating both external session formats with one
parser left that context in the imported message and generated title.
## What changed
- Route detected sessions through format-specific Claude and Cursor parsers.
- Strip recognized Cursor context wrappers when extracting a trailing
`<user_query>`, while preserving messages with unknown leading context.
- Keep shared content-block, tool-call, and timestamp parsing in a common module.
## Testing
Add parser coverage for wrapped Cursor queries, unknown context, working-directory
precedence, Claude metadata, content hashing, and shared tool annotations.
GitOrigin-RevId: b49328d46ab4937e3c599588a3d3081e8ab798cd
## What changed
- Treat enabled plugins from `claude-code-plugins` as coming from
`anthropics/claude-code` when no marketplace source is already known.
- Preserve an explicitly discovered source instead of replacing it with the
inferred source.
## Testing
- Add a migration test covering inference from `enabledPlugins`.
GitOrigin-RevId: f061963356493027968e282a51538866d2bf31f4
## What changed
- Add `maxSessionAgeDays` and `maxSessions` to the external-agent config detection request.
- Apply the requested limits when discovering sessions from supported migration sources.
- Preserve the existing defaults of a 30-day maximum age and 50 sessions when either option is omitted.
GitOrigin-RevId: 46376e94b64f1f61d8776e34d82cdd2cdeb36ca0
## What changed
- Add the `SessionEnd` hook event to hook configuration, protocol schemas, analytics, and the hooks browser.
- Run matching hooks for root threads during shutdown, including app-server archive, delete, idle unload, and graceful shutdown. Flush the transcript first and provide the session ID, transcript path, working directory, and `reason: "other"`.
- Keep teardown bounded: hook output is advisory, the default timeout is one second, configured timeouts are capped at three seconds, and async hooks run synchronously with a warning.
## Testing
- Cover transcript availability, matcher selection, timeout normalization, ignored control output, subagent exclusion, archive/delete ordering, and graceful shutdown of multiple loaded threads.
GitOrigin-RevId: 5d19a658677a137caf836ed5042dcb43f5eb6d1a
## What changed
- Add stable `sub_error_type` values for external-agent session import failures,
including detection, preparation, configuration, thread storage, and ledger
update errors.
- Preserve these values through import results and analytics while leaving
unrelated plugin and memory errors unchanged.
## Testing
- Verify that a missing session reports `session_not_detected` in both the
completed import result and its analytics event.
GitOrigin-RevId: cbf1f52df4bb1ac107442c4afa0b130fa32ad0a5
## What changed
- Record imported resources through `extension_resource_files`, retain their source frontmatter, and avoid synthesizing rollout metadata.
- Keep project-specific knowledge in scoped memory and limit `memory_summary.md` to compact routing entries, placing undated imports under older topics.
- Treat only resource directories with a regular `scope.json` file as managed projects, ignoring unrelated metadata entries while continuing to support hidden project keys.
## Testing
- Add coverage for identifying managed projects by their `scope.json` marker.
GitOrigin-RevId: 504dbca7ecb98e7025c33cbea18ef005b1a1a33c
## What changed
- Move migration detection, import orchestration, models, and reporting from
`codex-app-server` into `codex-external-agent-migration`.
- Keep app-server protocol conversion in a dedicated boundary module.
- Organize source-specific configuration, sessions, hooks, plugins, commands,
subagents, and memory handling behind shared migration adapters.
- Relocate and split the migration tests alongside the extracted service.
GitOrigin-RevId: 3378ec2064806a28136d6ac98664ca1d75414a4e
## What changed
- Detect and import supported Cursor settings, sandbox permissions, MCP servers,
project instructions, hooks, agents, commands, plugins, and recent chat
sessions.
- Update the `/import` flow to check Claude Code and Cursor, prompting for a
source when both have importable data.
- Add `migrationSource` to the app-server detect and import requests so each
operation uses the selected adapter, while retaining `source` for import
attribution and backwards compatibility.
## Testing
- Add coverage for Cursor config conversion, hooks, plugins, session discovery
and conversion, app-server imports, and TUI source selection.
GitOrigin-RevId: a65a1511b6c1c2f9e3e0cfe4f816bb435807282e
## What changed
- Correlate MCP server attribution in imported session records with connector
metadata, and persist normalized connector names in the session import ledger.
- Extend `externalAgentConfig/import/readHistories` with connector candidates,
including each connector's display name, imported-session count, and detection
source.
## Testing
- Cover connector detection through the session import and history-read flow.
- Verify candidate aggregation uses the latest import for each source session.
GitOrigin-RevId: 7f1f7f596925b2e6efcd17afd4490148e1ac9ff1
## What changed
- Convert supported plugin command Markdown into generated skills when a plugin is installed.
- Read command sources from the manifest's `commands` field, falling back to the plugin's `commands/` directory.
- Load generated command skills alongside native plugin skills while preferring native skills with the same name.
- Skip commands with unsupported templates, missing descriptions, name collisions, or generated skills larger than 4 KB, and keep migration failures from blocking plugin installation.
## Testing
- Cover default and manifest-configured command paths, stale generated skill cleanup, size limits, native-skill precedence, invalid manifest fields, and non-fatal migration errors.
GitOrigin-RevId: 67d910048544b160b191066569bca69b2b951ebc
## What changed
- Add an optional `source` selector to `externalAgentConfig/detect`, while preserving the existing behavior for omitted, `null`, and unrecognized values.
- Pass `claude-code` as the source for TUI detection and import requests.
- Move source-specific migration behavior behind an adapter boundary and consolidate session migration into `codex-external-agent-migration`.
## Testing
- Cover explicit, omitted, and unknown detection source values with app-server protocol tests.
- Add unit coverage for the extracted migration and hook helpers.
GitOrigin-RevId: 63bd3dcb485f3ad7bd996022db4e351506aeea77
## Why
Skill descriptions are used in model-visible lists: the default
available-skills catalog that supports implicit selection, and the
on-demand `skills.list` tool response used to discover orchestrator
skills. A single overlong description should not consume a
disproportionate share of either list.
Enforcing the 1024-character limit while loading or migrating skills is
the wrong boundary: it rejects otherwise-valid skills and discards
metadata that non-model consumers and full skill reads may need. Skill
metadata and `SKILL.md` content should remain intact; the cap belongs at
model-visible list rendering boundaries.
## What changed
- Preserve full `description` and `metadata.short-description` values
when loading skills.
- Preserve full external-agent command descriptions during
`source-command-*` migration instead of skipping commands solely because
their descriptions exceed 1024 characters.
- Preserve full normalized orchestrator descriptions in the underlying
skills catalog.
- Cap each description at 1024 Unicode characters when rendering the
default available-skills context in `codex-core-skills` and
`codex-skills-extension`.
- Apply the same cap when serializing descriptions in the model-visible
`skills.list` response.
- Render truncated descriptions as 1021 original characters plus `...`.
- Leave explicit `$skill` injection, `skills.read`, underlying metadata,
and on-disk `SKILL.md` files unchanged and full-fidelity.
## Implicit skill selection
Codex injects a bounded catalog containing each implicitly allowed
skill's name, description, and source locator, together with
instructions to use a skill when the task clearly matches its
description. The model makes that semantic choice; after selecting a
skill, it reads the full `SKILL.md` from its filesystem or provider
resource. Explicit `$skill` mentions remain a separate path that injects
the full skill instructions. For orchestrator skills, `skills.list`
provides bounded discovery metadata before `skills.read` returns the
full selected resource.
## Test plan
- `just test -p codex-core-skills`
- `just test -p codex-skills-extension`
- `just test -p codex-external-agent-migration`
The focused regressions verify that overlong metadata is preserved at
load and migration boundaries while default available-skills rendering
and `skills.list` output produce the 1021-character prefix plus `...`.
## Summary
- restore `externalAgentConfig/import/progress` notifications while
keeping `externalAgentConfig/import/completed` as the must-deliver event
- persist completed external-agent config imports in state DB by
`importId`, including concrete success/failure details for config,
AGENTS.md, skills, plugins, MCP servers, subagents, hooks, commands, and
sessions
- add `externalAgentConfig/import/readHistories` so clients can recover
persisted import results after missing the live completion notification
- include `errorType` on import failures in protocol
responses/notifications and persisted DB JSON so future code can
classify failures without another wire/storage shape change
## Validation
- `git diff --check`
- `just test -p codex-state external_agent_config_imports`
- `just test -p codex-app-server-protocol`
- `CODEX_SQLITE_HOME=/private/tmp/codex-app-server-sqlite-read-details
just test -p codex-app-server
external_agent_config_import_sends_completion_notification_for_sync_only_import`
Also ran earlier broader checks before publishing:
- `just test -p codex-state`
-
`CODEX_SQLITE_HOME=/private/tmp/codex-app-server-external-agent-test-sqlite
just test -p codex-app-server external_agent_config`
- `just test -p codex-external-agent-migration`
## Why
MCP migration could recursively merge an imported server into an
existing same-named Codex server. When one definition used stdio and the
other used HTTP, this produced an invalid mixed configuration containing
both `command` and `url`.
## What changed
- Merge MCP configuration at the server level instead of field by field.
- Preserve an existing same-named Codex MCP server unchanged.
- Report only MCP servers that would actually be added during detection.
- Add regression coverage for mixed command/HTTP source configurations.
- Use neutral fixture names and reserved `example.com` URLs.
## Test plan
- `just test -p codex-app-server repo_mcp`
- 5 tests passed.
- `just test -p codex-external-agent-migration
mcp_migration_prefers_command_transport_for_mixed_server_config`
- 1 test passed.
## Summary
- Rewrite migrated external-agent hook commands by replacing the full
hook script path token instead of only the `.claude/hooks/` segment.
- Preserve quoting around the full rewritten target path so script names
with spaces, absolute paths, and shell operators/redirection continue to
work.
- Apply `.claude/settings.local.json` over `.claude/settings.json` for
config, MCP, and plugin migration so local scope matches Claude settings
precedence.
- Skip legacy command markdown without `description` frontmatter,
including README-style docs under `.claude/commands`.
## Root Cause
The previous hook rewrite handled `.claude/hooks/` as a substring
replacement. For absolute source commands, that left the original
project-root prefix before the newly quoted `.codex/hooks` directory,
producing invalid commands like
`project/'project/.codex/hooks'/script.sh`.
The migration also only used project `settings.json` for
config/MCP/plugin decisions, so local settings such as
`disabledMcpjsonServers` could be ignored even though Claude gives local
settings higher precedence than project settings.
## Validation
- `just fmt`
- `cargo test -p codex-external-agent-migration`
- `cargo test -p codex-app-server external_agent_config`
- `just fix -p codex-external-agent-migration`
- `just fix -p codex-app-server`
- `git diff --check`
## Why
This PR expands the migration path so Codex can detect and import MCP
server config, hooks, commands, and subagents configs in a Codex-native
shape.
## What changed
- Added a `codex-external-agent-migration` crate that owns conversion
logic for external-agent MCP servers, hooks, commands, and subagents.
- Extended the app-server external-agent config detection/import API
with migration item types for MCP server config, hooks, commands, and
subagents.
## Migration strategy
The migration is intentionally conservative: Codex only imports
external-agent config that can be represented safely in Codex today.
Unsupported or ambiguous config is skipped instead of being partially
translated into behavior that may not match the source system.
- **MCP servers**: import supported stdio and HTTP MCP server
definitions into `mcp_servers`. Disabled servers and servers filtered
out by source `enabledMcpjsonServers` / `disabledMcpjsonServers` are
skipped. Project-scoped MCP entries from `.claude.json` are included
when they match the repo path.
- **Hooks**: import only supported command hooks into
`.codex/hooks.json`. Unsupported hook features such as conditional
groups, async handlers, prompt/http hooks, or unknown fields are
skipped. Referenced hook scripts are copied into `.codex/hooks/`,
preserving any existing target scripts.
- **Commands**: import supported external commands as Codex skills under
`.agents/skills/source-command-*`. Commands that rely on source runtime
expansion such as `$ARGUMENTS`, `$1`, `@file` references, shell
interpolation, or colliding generated names are skipped.
- **Subagents**: import valid subagent Markdown files into
`.codex/agents/*.toml` when they have the minimum Codex agent fields.
Source model names are not migrated, so imported agents keep the user’s
Codex default model; compatible reasoning effort and sandbox mode are
migrated when present.
- **Skills and project guidance**: copy missing skill directories into
`.agents/skills` and migrate `CLAUDE.md` guidance into `AGENTS.md`,
rewriting source-agent terminology to Codex terminology where
appropriate.
- **Detection details**: detected migration items include lightweight
details for UI preview, such as MCP server names, hook event names,
generated command skill names, and subagent names. Import still
recomputes from disk instead of trusting details as the source of truth.
- Adds focused coverage for the new migration behavior and app-server
import flow.
## Verification
- `cargo test -p codex-external-agent-migration`
- `cargo test -p codex-hooks`
- `cargo test -p codex-app-server external_agent_config`
