## What changed
- Load ordinary recursive host skill roots with the skills extension's host loader.
- Keep plugin-specific roots on the existing loader so plugin snapshot caching and namespacing continue to work.
- Merge both kinds of root snapshots through the existing precedence and deduplication logic, including discovery paths and source filesystem mappings.
- Move `HostSkillsSnapshot` into the skills extension as the owner of host skill loading.
## Testing
- Cover merged host and plugin catalogs, precedence for symlinked roots, discovery paths, and end-to-end rendering and invocation of host, repository, and plugin skills.
GitOrigin-RevId: c18080afb917c33c57bc17e36b40dd0f3c72d1d7
## What changed
- Share exact-name candidate lookup between resume and archive commands.
- Prefer valid SQLite names for local sessions, then recover legacy index names without overriding newer metadata.
- Validate rollout identity, collection, source, and model provider before selecting a local session, and choose the most recently modified eligible legacy duplicate.
- Preserve server-side lookup behavior for remote workspaces.
## Testing
- Cover stale and duplicate SQLite entries, legacy-name recovery, source and provider filtering, paginated histories, and duplicate legacy names.
GitOrigin-RevId: c69f86d64ff556bc7b463d13522a9241591eb070
## What changed
- Add end-to-end coverage for a remote environment whose provisioning status is
reported ready before it is selected for a turn.
- Verify that `wait_for_environment` makes remote execution tools and selected
capability-root context available once the transport is ready.
- Update pending-environment and relay tests to cover separate materialization
and readiness reporting, including deferred connection and reconnection.
GitOrigin-RevId: d86d66e8f722e9bafac88b93d93e7c5244a7156e
## What changed
- Share an in-flight `git status --porcelain` invocation among concurrent workspace metadata requests for the same canonical repository root.
- Keep scans for different repositories independent, and start a fresh scan after an in-flight request completes or loses all consumers.
- Pass the known repository root into dirty-worktree detection so requests from sibling directories and symlink aliases use the same key.
## Testing
- Add coverage for request coalescing, repository and symlink keying, completed scans, and consumer cancellation.
GitOrigin-RevId: 4c197c1d5bb94ca83c02979be34b17f24aefde08
## What changed
- Move the orchestrator skill catalog from thread context into its own
`orchestrator_skills` world-state section so unchanged catalogs remain
incremental across turns.
- Discover executor, orchestrator, and host catalogs together and render them
against one context-window-aware metadata budget, preserving executor entries
before orchestrator and host entries under pressure.
- Emit catalog metrics and budget warnings when each world-state section is
rendered.
## Testing
- Cover incremental orchestrator catalogs across production turns, combined
catalog budgeting, disabled and unavailable providers, caching, warnings, and
metrics.
GitOrigin-RevId: a0fb25d39dcaf43c978aff9da7972a1206f736e4
## What changed
- Add pending, ready, and failed provisioning states for Noise environments.
- Preserve the same environment instance whether provisioning is reported before or after materialization, and reject conflicts with ordinary environments.
- Make readiness and failure reports idempotent while rejecting contradictory terminal transitions.
- Delay connection attempts until a provisioned environment is selected and provisioning succeeds.
## Testing
- Cover status reports before and after materialization, terminal failures, repeated and contradictory reports, and replacement between ordinary and deferred environments.
GitOrigin-RevId: 4360a8f2a80c1a99a1dc9257e5d77c07b72b8eb3
## What changed
- Add `include_apps_usage_instructions` to model metadata, defaulting to true for compatibility with existing metadata.
- Emit generic Apps guidance only when apps are available and the selected model enables it.
- Enable the capability for interactive model presets while leaving `codex-auto-review` and local models opted out.
## Testing
- Verify that missing metadata defaults to enabled and an explicit opt-out survives serialization.
GitOrigin-RevId: 6a20573cddfd3b80083d2b4b015829b49e6cc283
## Why
Symlinked skills have a canonical `SKILL.md` path that can differ from the path
under the configured skill root. A catalog entry that advertises the discovery
path must still select the canonical skill.
## What changed
- Track each loaded skill's discovery path alongside its canonical identity.
- Render discovery paths in the skill catalog and accept either form for
structured selections and linked skill mentions.
- Preserve enabled-state checks, deduplication, and product filtering when
resolving discovery paths.
## Testing
Added loader, catalog, mention-resolution, and end-to-end turn coverage for
skills discovered through directory symlinks.
GitOrigin-RevId: bae539b766cc3782c7c121a4276c337699cbb509
## What changed
- Add the disabled-by-default `image_resize_notice` feature.
- When enabled, append a developer message after resized images from user
messages or tool outputs. The notice identifies each image and reports its
original and prepared dimensions.
- Persist notices with new history while avoiding backfilled notices for images
processed when a session is resumed.
## Testing
- Cover notice placement, image numbering, failed images, user and tool image
sources, and resumed-session replay.
GitOrigin-RevId: 11dd808b3ad47eac35e9e2f4a4370f85d0122770
## Why
Authentication restrictions must apply before stored or environment-provided credentials can be used, including during bootstrap before cloud requirements are fetched.
## What changed
- Add local `requirements.toml` allowlists for login methods and ChatGPT workspaces. Ignore these fields in cloud-provided requirements.
- Combine managed workspace allowlists with existing workspace restrictions by intersection, and fail closed when the resulting policy permits no usable login method.
- Centralize policy checks in the authentication manager so CLI, TUI, app-server, external-auth, and credential-loading paths consistently reject disallowed authentication before token hydration or network requests.
## Testing
- Cover policy composition, workspace intersection, invalid stored and external credentials, bootstrap enforcement, and login endpoint restrictions.
GitOrigin-RevId: efef22b248f3c3333e9aa55423e539efa2d2dd48
## What changed
- Make `PathUri` equality and hashing ignore ASCII case for inferred Windows
drive and UNC paths while preserving case-sensitive POSIX behavior.
- Apply the same convention-aware comparison to `starts_with` and
`relative_path_from`, including equivalent percent-encoded path spellings.
- Continue to fail closed for encoded path separators, opaque fallback URIs,
and non-ASCII case differences.
## Testing
- Add unit coverage for equality and hash consistency, Windows containment and
relative paths, POSIX case sensitivity, encoded separators, and non-ASCII
case differences.
GitOrigin-RevId: cd828874686a9cd242a36262ee3e7a9a172bd5b7
## What changed
- Move permission hooks, reviewer routing, approval caching, and user approval requests into the session-level approval flow.
- Have shell, unified exec, and apply-patch runtimes describe requests as `ApprovalAction` values, which now provide their hook payloads and cache keys.
- Pass a shared `ApprovalContext` through initial and retry approvals so telemetry and approval reasons are handled consistently.
GitOrigin-RevId: 5bfa61daa97e4427f3a648f6cf9d1c27f1551942
## What changed
- Add `create_session_with_limits` and session-scoped cell execution limits.
- Clamp execute and wait yield times to the session's `max_yield_time_ms`
without terminating the running cell.
- Negotiate support with remote code-mode hosts and include non-default limits
in `session/open`, while keeping unlimited sessions compatible with hosts and
providers that do not support limits.
## Testing
- Cover yield-time clamping, zero-timeout behavior, and isolation between
sessions.
- Cover wire serialization, capability negotiation, unsupported hosts, and
shared process-host execution.
GitOrigin-RevId: 9517321cd605bb87f93eeaa6ba331cc2e346e582
## Why
A stalled telemetry exporter can block shutdown indefinitely when the interactive TUI exits.
## What changed
- Add `OtelProvider::shutdown_with_timeout` to run exporter shutdown on a detached thread and report completion, worker failure, or timeout.
- Give interactive TUI telemetry shutdown a 500 ms time budget and warn if cleanup does not finish successfully.
## Testing
- Cover successful shutdown on current-thread and multi-thread Tokio runtimes, worker creation failure, and timeout behavior.
- Verify that OTLP HTTP shutdown returns on time when a collector stalls.
GitOrigin-RevId: 5b5f31a841fbc5788715cb3065d522c6dafa994f
## What changed
- Select `gpt-5.6-luna` for Guardian approval reviews authenticated with an API key, while retaining `codex-auto-review` for ChatGPT authentication.
- Exercise API-key reviews through Responses Lite and fall back to the bundled Guardian policy when the selected model has no catalog-provided review policy.
- Refine the bundled policy's handling of trusted authorization, sensitive-data egress, credential probing, destructive command targets, and post-denial approval.
## Testing
- Cover provider model selection for API-key and ChatGPT authentication.
- Verify Guardian prewarming and review reuse with both Responses Lite and standard Responses requests.
GitOrigin-RevId: e35c43e1692fd643ab8faad1444c0d6a869b3e0c
## What changed
- Cache an `McpBinding` on each published MCP runtime once server startup has
settled and the tool catalog revision is stable.
- Reuse the cached binding while the catalog revision remains unchanged, and
rebuild it after a runtime publish or catalog change.
- Treat terminal failures from optional servers as stable, while continuing to
wait for required servers and reconnecting Codex Apps servers.
## Testing
- Cover binding reuse within one published runtime and invalidation after a
republish.
- Cover stability checks for pending, failed optional, required, and
reconnected servers.
GitOrigin-RevId: 783a6b04897f6c484a6d56fd9cee542814041759
## What changed
Store the output buffer, notifications, closed state, and cancellation token
together in `OutputHandles`. Pass that shared bundle through output collection
and local output tasks instead of cloning and forwarding each field separately.
GitOrigin-RevId: 2f0f66dd419778e0b17ff47323c795f5dc88fe33
## Why
Signaling an MCP server's process group can fail with `EPERM` on macOS,
preventing owned descendants from being terminated.
## What changed
- When a group signal is denied, enumerate the group's processes and signal
members that still belong to the expected process group.
- Apply the fallback to both `SIGTERM` and `SIGKILL` during MCP stdio server
cleanup, while retaining the existing group signaling behavior elsewhere.
- Reject invalid process group IDs and avoid signaling processes that have
moved to another group.
## Testing
Added macOS tests covering cleanup with a live or exited group leader,
`SIGTERM`-resistant descendants, escalation to `SIGKILL`, and unsafe group IDs.
GitOrigin-RevId: db722475b94dece74244ce8109b3e92f6cfb202a
## Why
The 4 KiB aggregate limit can truncate source metadata before it reaches the
model through the tool search description.
## What changed
Raise the aggregate source-description limit to 512 KiB while retaining the
existing character-boundary-safe truncation and bounded output.
## Testing
Expand unit and RMCP round-trip coverage to verify that substantially longer
Unicode descriptions remain complete within the new limit.
GitOrigin-RevId: 002760cdd2e8741e531b45f75f8624ef84334d24
## What changed
- Propagate the optional `modelSpecialty` field through the model catalog and
app-server `model/list` response.
- When a newly selected model has the `cyber` specialty, default an active TUI
thread to workspace-write permissions with on-request approval. Use auto
review when available, otherwise keep the user as reviewer, while respecting
configured permission requirements.
- Show a notice when auto review is applied and strengthen the full-access
warning for cyber models.
- Preserve explicitly selected permissions when only reasoning settings change.
## Testing
- Cover auto-review defaults, requirement-aware fallback behavior, permission
preservation across reasoning changes, and the new warning notice.
GitOrigin-RevId: 8f25b0082d3051d9ff91f7355921236d0f82f758
## What changed
- Treat different non-empty descriptions for the same tool namespace as a
collision when `error_on_tool_collisions` is enabled, including deferred
tools.
- Continue allowing multiple tools to share a namespace when their descriptions
match or are empty.
- Preserve the first non-empty namespace description when strict collision
checking is disabled.
## Testing
- Cover strict collisions across direct and deferred tools, valid shared
namespaces, relaxed description merging, and failure before model sampling.
GitOrigin-RevId: 788a2ae0eccb64c97995af7a208d9abb79edf2d0
## What changed
- Build filesystem and permission context from the primary turn environment's permission profile, working directory, and workspace roots, falling back to the thread context when no primary environment is available.
- Build capability-discovery sandbox contexts from each environment's permission profile and treat discovery as restricted when any selected environment has restricted filesystem access.
## Testing
- Add regression tests covering environment-specific capability discovery and permission context updates.
GitOrigin-RevId: 6bbbd9b88aafa5e6583971ce4e427fc7557f2d93
## What changed
- Derive sandboxing, approval, and permission-profile environment variables from the selected turn environment for shell, unified exec, `apply_patch`, image viewing, and network approval flows.
- Materialize project-root permissions against every workspace root in that environment, allowing `apply_patch` to write to secondary workspace roots while preserving protected paths.
- Carry the selected environment's permission profile into spawned or resumed agents and Guardian permission context.
## Testing
- Add an integration test covering `apply_patch` writes in a secondary workspace root.
- Extend tool, Guardian, and multi-agent tests to distinguish environment permissions from thread-level permissions.
GitOrigin-RevId: e22da8974bcd3de1e724978b1a7790307a51e4bc
## What changed
- Expect tool collisions to report names canonicalized into the default
`functions` namespace.
- Remove the obsolete test that allowed an explicitly namespaced
`functions.shell_command` external tool.
GitOrigin-RevId: 9a517f49c027ffe5b811f6668dca91246f4925a6
## What changed
- Include the current permission profile in each turn environment's configuration.
- Refresh retained environment configurations when session settings change, while preserving the configuration already captured by active turns.
- Keep environment connection and shell snapshot resolution reusable across configuration updates.
## Testing
- Cover permission profile updates applied through both session settings updates and per-turn updates.
- Verify that pending environment resolutions use the configuration captured by their turn and that configuration-only updates do not retry failed environments.
GitOrigin-RevId: 923694f0729b87a118d7635ade3a8ca9bcd4e7b1
## What changed
- Track Agent Plugin manifests through plugin, skill, and MCP loading so their capabilities use format-specific behavior without changing legacy plugins.
- Discover only direct-child skills, exclude app and hook capabilities, isolate MCP data, and reject MCP configuration files that are non-regular or resolve outside the plugin root.
- Bound model-visible skill instructions, plugin instructions, MCP descriptions, schemas, individual tools, and the aggregate Agent Plugin MCP tool set.
- Stop MCP and OAuth redirects when Agent Plugins send configured or authorization headers, while retaining existing redirect behavior for legacy MCP servers.
## Testing
- Add coverage for capability filtering, skill discovery, isolated MCP data and reserved-path expansion, unsafe MCP configuration files, context limits, and redirect handling.
GitOrigin-RevId: c9af66b051269f3226628ca280a58d32c808c38f
## What changed
- Group top-level function and custom tool definitions into a single `functions` namespace for Responses Lite providers that support namespaced tools.
- Normalize missing, empty, and explicit `functions` namespaces to the same tool identity across registration, routing, lifecycle hooks, configuration, and tool search.
- Keep default tool names unprefixed in code mode, display output, and dispatch traces while preserving explicit non-default namespaces.
## Testing
- Add coverage for Responses Lite serialization, tool search results, namespace normalization and collision handling, routing, lifecycle events, and code-mode namespace policies.
GitOrigin-RevId: d48414005b5d22d39b11a198e19c47814d3a19f2
## What changed
- Track the first duplicate effective tool name while assembling the tool registry, including collisions introduced by external tools, code mode, and tool search.
- When `[features.tool_registry].error_on_tool_collisions` is enabled, fail the turn with a `duplicate tool: <namespace>.<name>` error before sending a model request.
- Continue allowing identical tool names in different namespaces, and preserve the existing collision behavior when strict checking is disabled.
## Testing
- Cover registry collision tracking, strict tool planning across tool sources, namespace isolation, failure before sampling, and pre-sampling compaction.
GitOrigin-RevId: 4cf83538fb513cec0b9c8b567780caaaadd3243d
## What changed
- Key cached skill snapshots by filesystem and plugin snapshot identity so compatible config and working-directory loads can share results without reusing stale plugin data.
- Coalesce concurrent loads for the same cache key and replace the cached entry on forced reload.
- Clear both plugin and skill caches when `skills/list` forces a reload, and bypass working-directory caching when effective plugin roots are present.
## Testing
- Cover concurrent cache sharing, filesystem isolation, forced reloads, and refreshed plugin skill metadata in host service and app server tests.
GitOrigin-RevId: 03fed3b40d45bb29206d5a3c3e78f06df04dbb1e
## What changed
- Include top-level freeform tools in the tool-search index and mark them for deferred loading.
- Serialize searched freeform tools as Responses API `custom` tools and convert them back into executable tool specs after discovery.
- Cover indexing and the end-to-end search, load, and custom-call routing flow.
GitOrigin-RevId: 124a7705876067542e1bd609546adc9a8d0ef67e
## Why
Clients using `thread/read` with `includeTurns: true` need the legacy full-history
view even when a thread stores its history in paginated form.
## What changed
- Reconstruct full projected turns from paginated history for both stored and
loaded threads.
- Keep `thread/turns/list` and `thread/items/list` as the preferred incremental
history APIs.
## Testing
- Cover `thread/read(includeTurns=true)` before and after a paginated thread is
loaded.
GitOrigin-RevId: 6efdc04e5ed3cad2ff2078d8103933082c7921db
## What changed
- Add the public asynchronous `ModelsCache` contract and cache entry/error types.
- Let model providers and `OpenAiModelsManager` accept caller-provided cache implementations while retaining the existing file-backed cache by default.
- Treat cache read failures as misses, keep cache write failures non-fatal, and support refreshing an entry's TTL after ETag revalidation.
- Continue to prefer an explicitly configured static model catalog over an injected cache.
## Testing
- Cover injected cache hits, read and write failures, TTL refreshes, and end-to-end model selection.
- Verify that the file-backed implementation satisfies the new cache contract and does not serve expired entries before revalidation.
GitOrigin-RevId: eef957a317910b8502a0c20f8fc112f689d5e389
## What changed
- Remove the hidden `PairProgramming` and `Execute` variants from `ModeKind`.
- Delete their unused prompt templates and simplify mode handling to cover only `Default` and `Plan`.
GitOrigin-RevId: 8d24e3f562a09e3071b2decae275d2b3871a1e9c
## Why
The bundled system-skill cache is shared by every process using the same
`CODEX_HOME`. A service with bundled skills disabled must not remove cache
files that another service still uses.
## What changed
- Filter system skill roots from disabled services without deleting the shared
cache.
- Ensure bundled system skills are installed during loads when they are
enabled, including after a runtime configuration change.
## Testing
Add app-server coverage for preserving the cache across enabled and disabled
services and refreshing stale cached skills after runtime enablement.
GitOrigin-RevId: 1eca999b33b7be69873a40a91767fd26f0c2b457
## Why
Sequential dispatch lets a long-running request block unrelated health checks
and cleanup on the same connection.
## What changed
- Add `--concurrent-requests <COUNT>` for local and remote exec-server
connections, while retaining sequential dispatch when the option is omitted
or set to `1`.
- Preserve handshake ordering before enabling concurrent dispatch.
- Reserve separate capacity for status, signal, terminate, and close requests so
they remain responsive when ordinary request capacity is saturated.
- Drain queued client responses during disconnect and cancel outstanding
request tasks during connection shutdown.
## Testing
- Cover CLI parsing and concurrency-limit validation.
- Verify default sequential behavior, pipelined handshake ordering, concurrent
request progress, control-request responsiveness, and disconnect handling.
GitOrigin-RevId: 48e4b092e318204ed635543f01f9ee0e7df095fc
## What changed
- Add a hidden global `--psp` runtime flag and propagate it through TUI, exec,
app-server, remote-control, and in-process startup paths.
- Attach the `oai-chat-psp=true` cookie to first-party ChatGPT requests when
enabled, using a cached cookie-aware client with sensitive request logging
disabled.
- Keep the routing selection out of persistent configuration layers while
preserving it across config refreshes and agent role changes.
## Testing
- Cover global flag parsing, app-server propagation, config-layer isolation,
and preservation across config rebuilds and role changes.
GitOrigin-RevId: 05cdc61ffd7162d8e48fc1e166f4732113e5a816
## What changed
- Let `HttpClientFactory` carry additional ChatGPT cookies and share their store across cloned factories.
- Attach configured cookies when route-aware clients or explicitly opted-in clients enable the ChatGPT cookie store.
- Combine configured cookies with the current path-scoped Cloudflare cookies only for HTTPS ChatGPT hosts, while preserving sensitive-header metadata.
## Testing
- Cover cookie merging, path-scoped Cloudflare updates, host and scheme restrictions, sensitive values, and factory clone/equality behavior.
GitOrigin-RevId: 5baf745859e14db739fd62ab931720dbe90c04e0
## What changed
- Treat an MCP server as trusted for ChatGPT authentication when its origin
matches the configured HTTPS `chatgpt-staging.com` host or one of its
subdomains.
- Continue trusting the production ChatGPT origin and falling back to OAuth for
other transports and origins.
## Testing
- Cover both the staging apex domain and a staging subdomain.
GitOrigin-RevId: 1b1d06ab214141d39eb38d46de9dfb74e6fedb3e
## What changed
- Add provider-owned remote compaction capabilities for unsupported, v1, and v2 protocols.
- Mark Amazon Bedrock as v1-only so manual and automatic compaction use `/v1/responses/compact`, even when the v2 feature is enabled.
- Preserve v2 support for OpenAI and Azure Responses providers and local compaction for unsupported providers.
## Testing
- Cover Amazon Bedrock manual and automatic remote compaction, including endpoint selection, authentication headers, model selection, and reuse of the compacted summary.
GitOrigin-RevId: d58093178605d1f8155b93d9a161408177f6ac72
## 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
Orchestrator skills with `allow_implicit_invocation: false` were still exposed in the model-visible skill catalog.
## What changed
- Hide explicit-only orchestrator skills from the prompt catalog while keeping them available for direct invocation.
- Include orchestrator resource-access metadata with injected instructions so `skills.read` can load referenced resources.
- Track visible and hidden discovery limits separately, and record discovery duration and resource-count metrics.
## Testing
Add an integration test that verifies an explicit-only orchestrator skill stays out of the prompt catalog, can be selected explicitly, and can read a referenced resource.
GitOrigin-RevId: 9cab5a61eb27c96bec9d1346c7dcdbc97376f7dc
## What changed
- Add a `features.token_budget.mode` setting with `thread` and `name` values.
- Default context-window metadata to the thread ID while allowing configurations to retain the agent name.
- Preserve the selected identity mode when applying model token-budget defaults and replaying locked configuration.
## Testing
- Cover configuration parsing and both identity formats in token-budget context messages.
GitOrigin-RevId: f6e6d2c49e09e70c0352e803bb65784ef77e5bee
## What changed
- Ignore symbolic links and other non-file, non-directory entries while copying a plugin into the store instead of rejecting the installation.
- Cover symlinked skill files and executables, verifying that the plugin installs without copying either link.
GitOrigin-RevId: da0cbbd95d12313afcaecdcb52824fc1922d0b74
## What changed
- Add the stable, default-enabled `features.view_image` flag.
- Omit the native `view_image` tool when the flag is disabled, including for fresh-context subagents and guardian reviewer turns.
- Keep unrelated execution and MCP tools available when the viewer is disabled.
## Testing
- Add app-server coverage for disabled viewer inheritance in fresh-context subagents and guardian reviewer turns.
GitOrigin-RevId: 42b1311010fbde9f064129b17b425820861c6d91
## 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
- Update the required pull request attribution to `Generated with [Codex](https://openai.com/codex/).`.
- Recognize the previous unlinked attribution when restoring saved context so it can be replaced without duplicating the attribution instructions.
## Testing
- Cover cold resume with both commit-only legacy instructions and the previous unlinked pull request attribution.
- Update app-server and MCP server assertions for the linked attribution.
GitOrigin-RevId: 8773546a6a59dab146905e50cf4434d53b9335cf
## Why
Trusting a directory enables project-local config, hooks, and exec policies, which can increase exposure to prompt injection. Require an explicit decision instead of automatically trusting projects whose trust level is unset.
## What changed
- Add a directory-trust step to TUI onboarding, with options to trust and continue or quit.
- Apply trust to the Git repository root when starting from a subdirectory, persist the decision, and reload config before continuing.
- Keep the prompt active and show the config error when trust cannot be persisted. Skip the prompt for remote workspaces and projects with an explicit trust level.
## Testing
- Cover trust-screen rendering, keyboard selection, persistence failures, and prompt visibility for explicit trust and Windows sandbox states.
GitOrigin-RevId: 850e6f54aec84d584cd161348ecdb1da89aaabd4
## 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
## Why
Image resize notices describe the history item immediately before them, so
remote compaction must not preserve or discard them independently of that item.
## What changed
- Group recognized `image_resize_notice` developer messages with their source
history items when filtering compacted history.
- Account for each group together when trimming or truncating history to a token
budget, preserving the notice only when its source is retained.
## Testing
- Extend the remote compaction v2 follow-up test to verify that a retained user
image keeps its resize notice, while notices for discarded items and
unrecognized developer notices are omitted.
GitOrigin-RevId: 82bb70a46eb68b07b4601e7fb345921d0789f442
## What changed
- Add `features.tool_registry.error_on_tool_collisions`, defaulting to `false`, to the TOML model, generated schema, and resolved runtime configuration.
- Treat `tool_registry` as structured configuration rather than a feature toggle, including in strict config validation and profile configuration.
