## Summary
- omit serialized Responses instructions when an app-server base
instruction override is empty
- skip empty developer instruction messages and add v2 coverage for the
empty-override request shape
## Validation
- just fmt
- git diff --check
## TL;DR
- New `Ctrl+O` shortcut on top of the existing `/copy` command, allowing
users to copy the latest agent response without having to cancel a plan
or type `/copy`
- Copy server clipboard to the client over SSH (OSC 52)
- Fixes linux copy behavior: a clipboard handle has to be kept alive
while the paste happens for the contents to be preserved
- Uses arboard as primary mechanism on Windows, falling back to
PowerShell copy clipboard function
- Works with resumes, rolling back during a session, etc.
Tested on macOS, Linux/X11, Windows WSL2, Windows cmd.exe, Windows
PowerShell, Windows VSCode PowerShell, Windows VSCode WSL2, SSH (macOS
-> macOS).
## Problem
The TUI's `/copy` command was fragile. It relied on a single
`last_copyable_output` field that was bluntly cleared on every rollback
and thread reconfiguration, making copied content unavailable after
common operations like backtracking. It also had no keyboard shortcut,
requiring users to type `/copy` each time. The previous clipboard
backend mixed platform selection policy with low-level I/O in a way that
was hard to test, and it did not keep the Linux clipboard owner alive —
meaning pasted content could vanish once the process that wrote it
dropped its `arboard::Clipboard`.
This addresses the text-copy failure modes reported in #12836, #15452,
and #15663: native Linux clipboard access failing in remote or
unreachable-display environments, copy state going blank even after
visible assistant output, and local Linux X11 reporting success while
leaving the clipboard empty.
## Shortcut rationale
The copy hotkey is `Ctrl+O` rather than `Alt+C` because Alt/Option
combinations are not delivered consistently by macOS terminal emulators.
Terminal.app and iTerm2 can treat Option as text input or as a
configurable Meta/Esc prefix, and Option+C may be consumed or
transformed before the TUI sees an `Alt+C` key event. `Ctrl+O` is a
stable control-key chord in Terminal.app, iTerm2, SSH, and the existing
cross-platform terminal stack.
## Mental model
Agent responses are now tracked as a bounded, ordinal-indexed history
(`agent_turn_markdowns: Vec<AgentTurnMarkdown>`) rather than a single
nullable string. Each completed agent turn appends an entry keyed by its
ordinal (the number of user turns seen so far). Rollbacks pop entries
whose ordinal exceeds the remaining turn count, then use the visible
transcript cells as a best-effort fallback if the ordinal history no
longer has a surviving entry. This means `/copy` and `Ctrl+O` reflect
the most recent surviving agent response after a backtrack, instead of
going blank.
The clipboard backend was rewritten as `clipboard_copy.rs` with a
strategy-injection design: `copy_to_clipboard_with` accepts closures for
the OSC 52, arboard, and WSL PowerShell paths, making the selection
logic fully unit-testable without touching real clipboards. On Linux,
the `Clipboard` handle is returned as a `ClipboardLease` stored on
`ChatWidget`, keeping X11/Wayland clipboard ownership alive for the
lifetime of the TUI. When native copy fails under WSL, the backend now
tries the Windows clipboard through PowerShell before falling back to
OSC 52.
## Non-goals
- This change does not introduce rich-text (HTML) clipboard support; the
copied content is raw markdown.
- It does not add a paste-from-history picker or multi-entry clipboard
ring.
- WSL support remains a best-effort fallback, not a new configuration
surface or guarantee for every terminal/host combination.
## Tradeoffs
- **Bounded history (256 entries)**: `MAX_AGENT_COPY_HISTORY` caps
memory. For sessions with thousands of turns this silently drops the
oldest entries. The cap is generous enough for realistic sessions.
- **`saw_copy_source_this_turn` flag**: Prevents double-recording when
both `AgentMessage` and `TurnComplete.last_agent_message` fire for the
same turn. The flag is reset on turn start and on turn complete,
creating a narrow window where a race between the two events could
theoretically skip recording. In practice the protocol delivers them
sequentially.
- **Transcript fallback on rollback**:
`last_agent_markdown_from_transcript` walks the visible transcript cells
to reconstruct plain text when the ordinal history has been fully
truncated. This path uses `AgentMessageCell::plain_text()` which joins
rendered spans, so it reconstructs display text rather than the original
raw markdown. It keeps visible text copyable after rollback, but
responses with markdown-specific syntax can diverge from the original
source.
- **Clipboard fallback ordering**: SSH still uses OSC 52 exclusively
because native/PowerShell clipboard access would target the wrong
machine. Local sessions try native clipboard first, then WSL PowerShell
when running under WSL, then OSC 52. This adds one process-spawn
fallback for WSL users but keeps the normal desktop and SSH paths
simple.

## Observability
- `tracing::warn!` on native clipboard failure before OSC 52 fallback.
- `tracing::debug!` on `/dev/tty` open/write failure before stdout
fallback.
- History cell messages: "Copied last message to clipboard", "Copy
failed: {error}", "No agent response to copy" appear in the TUI
transcript.
## Tests
- `clipboard_copy.rs`: Unit tests cover OSC 52 encoding roundtrip,
payload size rejection, writer output, SSH-only OSC52 routing, non-WSL
native-to-OSC52 fallback, WSL native-to-PowerShell fallback, WSL
PowerShell-to-OSC52 fallback, and all-error reporting via strategy
injection.
- `chatwidget/tests/slash_commands.rs`: Updated existing `/copy` tests
to use `last_agent_markdown_text()` accessor. Added coverage for the
Linux clipboard lease lifecycle, missing
`TurnComplete.last_agent_message` fallback through completed assistant
items, replayed legacy agent messages, stale-output prevention after
rollback, and the `Ctrl+O` no-output hotkey path.
- `app_backtrack.rs`: Added
`agent_group_count_ignores_context_compacted_marker` verifying that
info-event cells don't inflate the agent group count.

- [x] Expand tool search to custom MCPs.
- [x] Rename several variables/fields to be more generic.
Updated tool & server name lifecycles:
**Raw Identity**
ToolInfo.server_name is raw MCP server name.
ToolInfo.tool.name is raw MCP tool name.
MCP calls route back to raw via parse_tool_name() returning
(tool.server_name, tool.tool.name).
mcpServerStatus/list now groups by raw server and keys tools by
Tool.name: mod.rs:599
App-server just forwards that grouped raw snapshot:
codex_message_processor.rs:5245
**Callable Names**
On list-tools, we create provisional callable_namespace / callable_name:
mcp_connection_manager.rs:1556
For non-app MCP, provisional callable name starts as raw tool name.
For codex-apps, provisional callable name is sanitized and strips
connector name/id prefix; namespace includes connector name.
Then qualify_tools() sanitizes callable namespace + name to ASCII alnum
/ _ only: mcp_tool_names.rs:128
Note: this is stricter than Responses API. Hyphen is currently replaced
with _ for code-mode compatibility.
**Collision Handling**
We do initially collapse example-server and example_server to the same
base.
Then qualify_tools() detects distinct raw namespace identities behind
the same sanitized namespace and appends a hash to the callable
namespace: mcp_tool_names.rs:137
Same idea for tool-name collisions: hash suffix goes on callable tool
name.
Final list_all_tools() map key is callable_namespace + callable_name:
mcp_connection_manager.rs:769
**Direct Model Tools**
Direct MCP tool declarations use the full qualified sanitized key as the
Responses function name.
The raw rmcp Tool is converted but renamed for model exposure.
**Tool Search / Deferred**
Tool search result namespace = final ToolInfo.callable_namespace:
tool_search.rs:85
Tool search result nested name = final ToolInfo.callable_name:
tool_search.rs:86
Deferred tool handler is registered as "{namespace}:{name}":
tool_registry_plan.rs:248
When a function call comes back, core recombines namespace + name, looks
up the full qualified key, and gets the raw server/tool for MCP
execution: codex.rs:4353
**Separate Legacy Snapshot**
collect_mcp_snapshot_from_manager_with_detail() still returns a map
keyed by qualified callable name.
mcpServerStatus/list no longer uses that; it uses
McpServerStatusSnapshot, which is raw-inventory shaped.
## Summary
App-server v2 already receives turn-scoped `clientMetadata`, but the
Rust app-server was dropping it before the outbound Responses request.
This change keeps the fix lightweight by threading that metadata through
the existing turn-metadata path rather than inventing a new transport.
## What we're trying to do and why
We want turn-scoped metadata from the app-server protocol layer,
especially fields like Hermes/GAAS run IDs, to survive all the way to
the actual Responses API request so it is visible in downstream
websocket request logging and analytics.
The specific bug was:
- app-server protocol uses camelCase `clientMetadata`
- Responses transport already has an existing turn metadata carrier:
`x-codex-turn-metadata`
- websocket transport already rewrites that header into
`request.request_body.client_metadata["x-codex-turn-metadata"]`
- but the Rust app-server never parsed or stored `clientMetadata`, so
nothing from the app-server request was making it into that existing
path
This PR fixes that without adding a new header or a second metadata
channel.
## How we did it
### Protocol surface
- Add optional `clientMetadata` to v2 `TurnStartParams` and
`TurnSteerParams`
- Regenerate the JSON schema / TypeScript fixtures
- Update app-server docs to describe the field and its behavior
### Runtime plumbing
- Add a dedicated core op for app-server user input carrying turn-scoped
metadata: `Op::UserInputWithClientMetadata`
- Wire `turn/start` and `turn/steer` through that op / signature path
instead of dropping the metadata at the message-processor boundary
- Store the metadata in `TurnMetadataState`
### Transport behavior
- Reuse the existing serialized `x-codex-turn-metadata` payload
- Merge the new app-server `clientMetadata` into that JSON additively
- Do **not** replace built-in reserved fields already present in the
turn metadata payload
- Keep websocket behavior unchanged at the outer shape level: it still
sends only `client_metadata["x-codex-turn-metadata"]`, but that JSON
string now contains the merged fields
- Keep HTTP fallback behavior unchanged except that the existing
`x-codex-turn-metadata` header now includes the merged fields too
### Request shape before / after
Before, a websocket `response.create` looked like:
```json
{
"type": "response.create",
"client_metadata": {
"x-codex-turn-metadata": "{\"session_id\":\"...\",\"turn_id\":\"...\"}"
}
}
```
Even if the app-server caller supplied `clientMetadata`, it was not
represented there.
After, the same request shape is preserved, but the serialized payload
now includes the new turn-scoped fields:
```json
{
"type": "response.create",
"client_metadata": {
"x-codex-turn-metadata": "{\"session_id\":\"...\",\"turn_id\":\"...\",\"fiber_run_id\":\"fiber-start-123\",\"origin\":\"gaas\"}"
}
}
```
## Validation
### Targeted tests added / updated
- protocol round-trip coverage for `clientMetadata` on `turn/start` and
`turn/steer`
- protocol round-trip coverage for `Op::UserInputWithClientMetadata`
- `TurnMetadataState` merge test proving client metadata is added
without overwriting reserved built-in fields
- websocket request-shape test proving outbound `response.create`
contains merged metadata inside
`client_metadata["x-codex-turn-metadata"]`
- app-server integration tests proving:
- `turn/start` forwards `clientMetadata` into the outbound Responses
request path
- websocket warmup + real turn request both behave correctly
- `turn/steer` updates the follow-up request metadata

## Summary
- bridge Codex Apps tools that declare `_meta["openai/fileParams"]`
through the OpenAI file upload flow
- mask those file params in model-visible tool schemas so the model
provides absolute local file paths instead of raw file payload objects
- rewrite those local file path arguments client-side into
`ProvidedFilePayload`-shaped objects before the normal MCP tool call
## Details
- applies to scalar and array file params declared in
`openai/fileParams`
- Codex uploads local files directly to the backend and uses the
uploaded file metadata to build the MCP tool arguments locally
- this PR is input-only
## Verification
- `just fmt`
- `cargo test -p codex-core mcp_tool_call -- --nocapture`

## What
Show an inline `ctrl + t to view transcript` hint when exec output is
truncated in the main TUI chat view.
## Why
Today, truncated exec output shows `… +N lines`, but it does not tell
users that the full content is already available through the existing
transcript overlay. That makes hidden output feel lost instead of
discoverable.
This change closes that discoverability gap without introducing a new
interaction model.
Fixes: CLI-5740
## How
- added an output-specific truncation hint in `ExecCell` rendering
- applied that hint in both exec-output truncation paths:
- logical head/tail truncation before wrapping
- row-budget truncation after wrapping
- preserved the existing row-budget behavior on narrow terminals by
reserving space for the longer hint line
- updated the relevant snapshot and added targeted regression coverage
## Intentional design decisions
- **Aligned shortcut styling with the visible footer UI**
The inline hint uses `ctrl + t`, not `Ctrl+T`, to match the TUI’s
rendered key-hint style.
- **Kept the noun `transcript`**
The product already exposes this flow as the transcript overlay, so the
hint points at the existing concept instead of inventing a new label.
- **Preserved narrow-terminal behavior**
The longer hint text is accounted for in the row-budget truncation path
so the visible output still respects the existing viewport cap.
- **Did not add the hint to long command truncation**
This PR only changes hidden **output** truncation. Long command
truncation still uses the plain ellipsis form because `ctrl + t` is not
the same kind of “show hidden output” escape hatch there.
- **Did not widen scope to other truncation surfaces**
This does not change MCP/tool-call truncation in `history_cell.rs`, and
it does not change transcript-overlay behavior itself.
## Validation
### Automated
- `just fmt`
- `cargo test -p codex-tui`
### Manual
- ran `just tui-with-exec-server`
- executed `!seq 1 200`
- confirmed the main view showed the new `ctrl + t to view transcript`
truncation hint
- pressed `ctrl + t` and confirmed the transcript overlay still exposed
the full output
- closed the overlay and returned to the main view
## Visual proof
Screenshot/video attached in the PR UI showing:
- the truncated exec output row with the new hint
- the transcript overlay after `ctrl + t`
## Summary
- Replace Codex-branded network-proxy block responses with concise
reason text
- Mention sandbox policy for local/private network and deny-policy
wording
- Remove “managed” from the proxy-disabled denial detail

## Summary
- detect remote exec-server sessions in the unified-exec runtime
- bypass the local shell-snapshot bootstrap only for those remote
sessions
- preserve existing local snapshot wrapping, PowerShell UTF-8 prefixing,
sandbox orchestration, and zsh-fork handling
## Why
The shell snapshot file is currently captured and stored next to Core.
If Core wraps a remote command with `. /path/to/local/snapshot`, the
process starts on the executor and tries to source a path from the
orchestrator filesystem. This keeps remote commands from receiving that
known-local path until shell snapshots are captured/restored on the
executor side.
## Validation
- `just fmt`
- `git diff --check`
- `cargo test -p codex-core --lib tools::runtimes::tests`

Problem: The statusline reported context as an “X% left” value, which
could be mistaken for quota, and context usage was included in the
default footer.
Solution: Render configured context status items as a filling context
meter, preserve `context-used` as a legacy alias while hiding it from
the setup menu, and remove context from the default statusline. It will
still be available as an opt-in option for users who want to see it.

## Summary
- keep pending steered input buffered until the active user prompt has
received a model response
- keep steering pending across auto-compact when there is real
model/tool continuation to resume
- allow queued steering to follow compaction immediately when the prior
model response was already final
- keep pending-input follow-up owned by `run_turn` instead of folding it
into `SamplingRequestResult`
- add regression coverage for mid-turn compaction, final-response
compaction, and compaction triggered before the next request after tool
output
## Root Cause
Steered input was drained at the top of every `run_turn` loop. After
auto-compaction, the loop continued and immediately appended any pending
steer after the compact summary, making a queued prompt look like the
newest task instead of letting the model first resume interrupted
model/tool work.
## Implementation Notes
This patch keeps the follow-up signals separated:
- `SamplingRequestResult.needs_follow_up` means model/tool continuation
is needed
- `sess.has_pending_input().await` means queued user steering exists
- `run_turn` computes the combined loop condition from those two signals
In `run_turn`:
```rust
let has_pending_input = sess.has_pending_input().await;
let needs_follow_up = model_needs_follow_up || has_pending_input;
```
After auto-compact we choose whether the next request may drain
steering:
```rust
can_drain_pending_input = !model_needs_follow_up;
```
That means:
- model/tool continuation + pending steer: compact -> resume once
without draining steer
- completed model answer + pending steer: compact -> drain/send the
steer immediately
- fresh user prompt: do not drain steering before the model has answered
the prompt once
The drain is still only `sess.get_pending_input().await`; when
`can_drain_pending_input` is false, core uses an empty local vec and
leaves the steer pending in session state.
## Validation
- PASS `cargo test -p codex-core --test all steered_user_input --
--nocapture`
- PASS `just fmt`
- PASS `git diff --check`
- NOT PASSING HERE `just fix -p codex-core` currently stops before
linting this change on an unrelated mainline test-build error:
`core/src/tools/spec_tests.rs` initializes `ToolsConfigParams` without
`image_generation_tool_auth_allowed`; this PR does not touch that file.

Addresses #17166
Problem: Source builds report version 0.0.0, so the TUI update path can
treat any released Codex version as upgradeable and show startup or
popup prompts.
Solution: Skip both TUI update prompt entry points when the running CLI
version is the source-build sentinel 0.0.0.
- Default realtime sessions to v2 and gpt-realtime-1.5 when no override
is configured.
- Add Op::RealtimeConversationStart integration coverage and keep
v1-specific tests explicit.

Problem: TUI desktop notifications are hard-gated on terminal focus, so
terminal/IDE hosts that want in-focus notifications cannot opt in.
Solution: Add a flat `[tui] notification_condition` setting (`unfocused`
by default, `always` opt-in), carry grouped TUI notification settings
through runtime config, apply method + condition together in the TUI,
and regenerate the config schema.
- Adds a core-owned realtime backend prompt template and preparation
path.
- Makes omitted realtime start prompts use the core default, while null
or empty prompts intentionally send empty instructions.
- Covers the core realtime path and app-server v2 path with integration
coverage.

Addresses #15943
Problem: Name-based resume could stop on a newer session_index entry
whose rollout was never persisted, shadowing an older saved thread with
the same name.
Solution: Materialize rollouts before indexing thread names and make
name lookup skip unresolved entries until it finds a persisted rollout.
Problem: Warp supports OSC 9 notifications, but the TUI's automatic
notification backend selection did not recognize its
`TERM_PROGRAM=WarpTerminal` environment value.
Solution: Treat `TERM_PROGRAM=WarpTerminal` as OSC 9-capable when
choosing the TUI desktop notification backend.
Currently, when a MCP server sends an elicitation to Codex running in
Full Access (`sandbox_policy: DangerFullAccess` + `approval_policy:
Never`), the elicitations are auto-cancelled.
This PR updates the automatic handling of MCP elicitations to be
consistent with other approvals in full-access, where they are
auto-approved. Because MCP elicitations may actually require user input,
this mechanism is limited to empty form elicitations.
## Changeset
- Add policy helper shared with existing MCP tool call approval
auto-approve
- Update `ElicitationRequestManager` to auto-approve elicitations in
full access when `can_auto_accept_elicitation` is true.
- Add tests

**Disabling Image-Gen for Non-SIWC Codex Users**
We are only enabling image-gen feature for SIWC Codex users until there
comes a fix in ResponsesAPI to omit output from responses.completed, to
prevent the following issues:
1. websocket blows up due to heavier load (images) than before (text)
2. http parser streams through n^2 of n-base64 bytes (sum of base64s of
all images generated in turn) that causes long delays in
turn_completion.
## Description
This PR fixes `/debug-config` so it shows more of the active
requirements state, including reviewer requirements and managed feature
pins. This made it clear that legacy MDM config was setting
`approvals_reviewer = "guardian_subagent"` and that we were translating
that into a requirements constraint.
Also, translate `approvals_reviewer = "guardian_subagent"` (from legacy
managed_config.toml) to `allowed_approvals_reviewers: guardian_subagent,
user` instead of `allowed_approvals_reviewers: guardian_subagent`.
Example `/debug-config`:
```
Config layer stack (lowest precedence first):
1. system (/etc/codex/config.toml) (enabled)
2. user (/Users/owen/.codex/config.toml) (enabled)
3. project (/Users/owen/repos/codex/.codex/config.toml) (enabled)
4. legacy managed_config.toml (MDM) (enabled)
MDM value:
...
# Enable Guardian Mode
features.guardian_approval = true
approvals_reviewer = "guardian_subagent"
Requirements:
- allowed_approvals_reviewers: guardian_subagent, user (source: MDM managed_config.toml (legacy))
- features: apps=true, plugins=true (source: cloud requirements)
```
Before this PR, the `Requirements` section showed None.
## Summary
- Carry `AbsolutePathBuf` through tool cwd parsing/resolution instead of
resolving workdirs to raw `PathBuf`s.
- Type exec/sandbox request cwd fields as `AbsolutePathBuf` through
`ExecParams`, `ExecRequest`, `SandboxCommand`, and unified exec runtime
requests.
- Keep `PathBuf` conversions at external/event boundaries and update
existing tests/fixtures for the typed cwd.

Problem: Resuming the live TUI thread through `/resume` could
unsubscribe and reconnect the same app-server thread, leaving the UI
crashed or disconnected.
Solution: No-op `/resume` only when the selected thread is the currently
attached active thread; keep the normal resume path for
stale/displayed-only threads so recovery and reattach still work.
Addresses #3793
Problem: /status only reported project-level AGENTS files, so sessions
with a loaded global $CODEX_HOME/AGENTS.md still showed Agents.md as
<none>.
Solution: Track the global instructions file loaded during config
initialization and prepend that path to the /status Agents.md summary,
with coverage for AGENTS.md, AGENTS.override.md, and global-plus-project
ordering.
Allow multi_agent_v2 features to have its own temporary configuration
under `[features.multi_agent_v2]`
```
[features.multi_agent_v2]
enabled = true
usage_hint_enabled = false
usage_hint_text = "Custom delegation guidance."
hide_spawn_agent_metadata = true
```
Absent `usage_hint_text` means use the default hint.
```
[features]
multi_agent_v2 = true
```
still works as the boolean shorthand.
