## Summary
This change removes the compiled permissions field from skill metadata
and keeps permission_profile as the single source of truth.
Skill loading no longer compiles skill permissions eagerly. Instead, the
zsh-fork skill escalation path compiles `skill.permission_profile` when
it needs to determine the sandbox to apply for a skill script.
## Behavior change
For skills that declare:
```
permissions: {}
```
we now treat that the same as having no skill permissions override,
instead of creating and using a default readonly sandbox. This change
makes the behavior more intuitive:
- only non-empty skill permission profiles affect sandboxing
- omitting permissions and writing permissions: {} now mean the same
thing
- skill metadata keeps a single permissions representation instead of
storing derived state too
Overall, this makes skill sandbox behavior easier to understand and more
predictable.
## Summary
- restore `Tab to queue` when a draft is present and the agent is
running
- keep draft-idle footers passive by showing the normal footer or status
line instead of `? for shortcuts`
- align footer snapshot coverage with the updated draft footer behavior

Addresses #12967
About a month ago, I updated the Github bug report templates to
accommodate the (at the time) new Codex app. The `/feedback` code path
in the CLI was referencing one of the old templates, and I didn't
realize it at the time. This PR updates the link so users don't get an
empty bug template when using `/feedback`.
Addresses https://github.com/openai/codex/issues/13040
Fixes a regression in 0.106.0 introduced in
https://github.com/openai/codex/pull/9393
Summary
- replace only the active completion range so unrelated text elements
(e.g., large-paste placeholders) stay atomic and can still expand
- add a regression test verifying large paste placeholders persist
through completions and submit
- could not fetch issue details via GitHub API because network access is
disabled in this sandboxed environment
## Why
`PermissionProfile` should describe filesystem roots as absolute paths
at the type level. Using `PathBuf` in `FileSystemPermissions` made the
shared type too permissive and blurred together three different
deserialization cases:
- skill metadata in `agents/openai.yaml`, where relative paths should
resolve against the skill directory
- app-server API payloads, where callers should have to send absolute
paths
- local tool-call payloads for commands like `shell_command` and
`exec_command`, where `additional_permissions.file_system` may
legitimately be relative to the command `workdir`
This change tightens the shared model without regressing the existing
local command flow.
## What Changed
- changed `protocol::models::FileSystemPermissions` and the app-server
`AdditionalFileSystemPermissions` mirror to use `AbsolutePathBuf`
- wrapped skill metadata deserialization in `AbsolutePathBufGuard`, so
relative permission roots in `agents/openai.yaml` resolve against the
containing skill directory
- kept app-server/API deserialization strict, so relative
`additionalPermissions.fileSystem.*` paths are rejected at the boundary
- restored cwd/workdir-relative deserialization for local tool-call
payloads by parsing `shell`, `shell_command`, and `exec_command`
arguments under an `AbsolutePathBufGuard` rooted at the resolved command
working directory
- simplified runtime additional-permission normalization so it only
canonicalizes and deduplicates absolute roots instead of trying to
recover relative ones later
- updated the app-server schema fixtures, `app-server/README.md`, and
the affected transport/TUI tests to match the final behavior
## Summary
- add a dedicated /audio picker for realtime microphone and speaker
selection
- persist realtime audio choices and prompt to restart only local audio
when voice is live
- add snapshot coverage for the new picker surfaces
## Validation
- cargo test -p codex-tui
- cargo insta accept
- just fix -p codex-tui
- just fmt
Currently there is no bound on the length of a user message submitted in
the TUI or through the app server interface. That means users can paste
many megabytes of text, which can lead to bad performance, hangs, and
crashes. In extreme cases, it can lead to a [kernel
panic](https://github.com/openai/codex/issues/12323).
This PR limits the length of a user input to 2**20 (about 1M)
characters. This value was chosen because it fills the entire context
window on the latest models, so accepting longer inputs wouldn't make
sense anyway.
Summary
- add a shared `MAX_USER_INPUT_TEXT_CHARS` constant in codex-protocol
and surface it in TUI and app server code
- block oversized submissions in the TUI submit flow and emit error
history cells when validation fails
- reject heavy app-server requests with JSON-RPC `-32602` and structured
`input_too_large` data, plus document the behavior
Testing
- ran the IDE extension with this change and verified that when I
attempt to paste a user message that's several MB long, it correctly
reports an error instead of crashing or making my computer hot.
Command-approval clients currently infer which choices to show from
side-channel fields like `networkApprovalContext`,
`proposedExecpolicyAmendment`, and `additionalPermissions`. That makes
the request shape harder to evolve, and it forces each client to
replicate the server's heuristics instead of receiving the exact
decision list for the prompt.
This PR introduces a mapping between `CommandExecutionApprovalDecision`
and `codex_protocol::protocol::ReviewDecision`:
```rust
impl From<CoreReviewDecision> for CommandExecutionApprovalDecision {
fn from(value: CoreReviewDecision) -> Self {
match value {
CoreReviewDecision::Approved => Self::Accept,
CoreReviewDecision::ApprovedExecpolicyAmendment {
proposed_execpolicy_amendment,
} => Self::AcceptWithExecpolicyAmendment {
execpolicy_amendment: proposed_execpolicy_amendment.into(),
},
CoreReviewDecision::ApprovedForSession => Self::AcceptForSession,
CoreReviewDecision::NetworkPolicyAmendment {
network_policy_amendment,
} => Self::ApplyNetworkPolicyAmendment {
network_policy_amendment: network_policy_amendment.into(),
},
CoreReviewDecision::Abort => Self::Cancel,
CoreReviewDecision::Denied => Self::Decline,
}
}
}
```
And updates `CommandExecutionRequestApprovalParams` to have a new field:
```rust
available_decisions: Option<Vec<CommandExecutionApprovalDecision>>
```
when, if specified, should make it easier for clients to display an
appropriate list of options in the UI.
This makes it possible for `CoreShellActionProvider::prompt()` in
`unix_escalation.rs` to specify the `Vec<ReviewDecision>` directly,
adding support for `ApprovedForSession` when approving a skill script,
which was previously missing in the TUI.
Note this results in a significant change to `exec_options()` in
`approval_overlay.rs`, as the displayed options are now derived from
`available_decisions: &[ReviewDecision]`.
## What Changed
- Add `available_decisions` to
[`ExecApprovalRequestEvent`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/protocol/src/approvals.rs#L111-L175),
including helpers to derive the legacy default choices when older
senders omit the field.
- Map `codex_protocol::protocol::ReviewDecision` to app-server
`CommandExecutionApprovalDecision` and expose the ordered list as
experimental `availableDecisions` in
[`CommandExecutionRequestApprovalParams`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/app-server-protocol/src/protocol/v2.rs#L3798-L3807).
- Thread optional `available_decisions` through the core approval path
so Unix shell escalation can explicitly request `ApprovedForSession` for
session-scoped approvals instead of relying on client heuristics.
[`unix_escalation.rs`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs#L194-L214)
- Update the TUI approval overlay to build its buttons from the ordered
decision list, while preserving the legacy fallback when
`available_decisions` is missing.
- Update the app-server README, test client output, and generated schema
artifacts to document and surface the new field.
## Testing
- Add `approval_overlay.rs` coverage for explicit decision lists,
including the generic `ApprovedForSession` path and network approval
options.
- Update `chatwidget/tests.rs` and app-server protocol tests to populate
the new optional field and keep older event shapes working.
## Developers Docs
- If we document `item/commandExecution/requestApproval` on
[developers.openai.com/codex](https://developers.openai.com/codex), add
experimental `availableDecisions` as the preferred source of approval
choices and note that older servers may omit it.
Summary
- propagate approval policy from parent to spawned agents and drop the
Never override so sub-agents respect the caller’s request
- refresh the pending-approval list whenever events arrive or the active
thread changes and surface the list above the composer for inactive
threads
- add widgets, helpers, and tests covering the new pending-thread
approval UI state

## Summary
- Preserve each skill’s raw permissions block as a permission_profile on
SkillMetadata during skill loading.
- Keep compiling that same metadata into the existing runtime
Permissions object, so current enforcement
behavior stays intact.
- When zsh-fork intercepts execution of a script that belongs to a
skill, include the skill’s
permission_profile in the exec approval request.
- This lets approval UIs show the extra filesystem access the skill
declared when prompting for approval.
This PR replaces the old `additional_permissions.fs_read/fs_write` shape
with a shared `PermissionProfile`
model and wires it through the command approval, sandboxing, protocol,
and TUI layers. The schema is adopted from the
`SkillManifestPermissions`, which is also refactored to use this unified
struct. This helps us easily expose permission profiles in app
server/core as a follow-up.
Rename `SkillMetadata.path` to `SkillMetadata.path_to_skills_md` for
clarity.
Would ideally change the type to `AbsolutePathBuf`, but that can be done
later.
- Add a hidden `realtime_conversation` feature flag and `/realtime`
slash command for start/stop live voice sessions.
- Reuse transcription composer/footer UI for live metering, stream mic
audio, play assistant audio, render realtime user text events, and
force-close on feature disable.

## Problem
Diff lines used only foreground colors (green/red) with no background
tinting, making them hard to scan. The gutter (line numbers) also had no
theme awareness — dimmed text was fine on dark terminals but unreadable
on light ones.
## Mental model
Each diff line now has four styled layers: **gutter** (line number),
**sign** (`+`/`-`), **content** (text), and **line background** (full
terminal width). A `DiffTheme` enum (`Dark` / `Light`) is selected once
per render by probing the terminal's queried background via
`default_bg()`. A companion `DiffColorLevel` enum (`TrueColor` /
`Ansi256` / `Ansi16`) is derived from `stdout_color_level()` and gates
which palette is used. All style helpers dispatch on `(theme,
DiffLineType, color_level)` to pick the right colors.

## Non-goals
- No runtime theme switching beyond what `default_bg()` already
provides.
- No change to syntax highlighting theme selection or the highlight
module.
## Tradeoffs
- Three fixed palettes (truecolor RGB, 256-color indexed, 16-color
named) are maintained rather than using `best_color` nearest-match. This
is deliberate: `supports_color::on_cached(Stream::Stdout)` can misreport
capabilities once crossterm enters the alternate screen, so hand-picked
palette entries give better visual results than automatic quantization.
- Delete lines in the syntax-highlighted path get `Modifier::DIM` to
visually recede compared to insert lines. This trades some readability
of deleted code for scan-ability of additions.
- The theme picker's diff preview sets `preserve_side_content_bg: true`
on `ListSelectionView` so diff background tints survive into the side
panel. Other popups keep the default (`false`) to preserve their
reset-background look.
## Architecture
- **Color constants** are module-level `const` items grouped by palette
tier: `DARK_TC_*` / `LIGHT_TC_*` (truecolor RGB tuples), `DARK_256_*` /
`LIGHT_256_*` (xterm indexed), with named `Color` variants used for the
16-color tier.
- **`DiffTheme`** is a private enum; `diff_theme()` probes the terminal
and `diff_theme_for_bg()` is the testable pure-function version.
- **`DiffColorLevel`** is a private enum derived from `StdoutColorLevel`
via `diff_color_level()`.
- **Palette helpers** (`add_line_bg`, `del_line_bg`, `light_gutter_fg`,
`light_add_num_bg`, `light_del_num_bg`) each take `(DiffTheme,
DiffColorLevel)` or just `DiffColorLevel` and return a `Color`.
- **Style helpers** (`style_line_bg_for`, `style_gutter_for`,
`style_sign_add`, `style_sign_del`, `style_add`, `style_del`) each take
`(DiffLineType, DiffTheme, DiffColorLevel)` or `(DiffTheme,
DiffColorLevel)` and return a `Style`.
- **`push_wrapped_diff_line_inner_with_theme_and_color_level`** is the
innermost renderer, accepting both theme and color level so tests can
exercise any combination without depending on the terminal.
- **Line-level background** is applied via
`RtLine::from(...).style(line_bg)` so the tint extends across the full
terminal width, not just the text content.
- **Theme picker integration**: `ListSelectionView` gained a
`preserve_side_content_bg` flag. When `true`, the side panel skips
`force_bg_to_terminal_bg`, letting diff preview backgrounds render
faithfully.
## Observability
No new logging. Theme selection is deterministic from `default_bg()`,
which is already queried and cached at TUI startup.
## Tests
1. **`DiffTheme` is determined per `render_change` call** — if
`default_bg()` changes mid-render (e.g. `requery_default_colors()`
fires), different file chunks could render with different themes. Low
risk in practice since re-query only happens on explicit user action.
2. **16-color tier uses named `Color` variants** (`Color::Green`,
`Color::Red`, etc.) which the terminal maps to its own palette. On
unusual terminal themes these could clash with the background.
Acceptable since 16-color terminals already have unpredictable color
rendering.
3. **Light-theme `style_add` / `style_del` set bg but no fg** — on light
terminals, non-syntax-highlighted content uses the terminal's default
foreground against a pastel background. If the terminal's default fg
happens to be very light, contrast could suffer. This is an edge case
since light-terminal users typically have dark default fg.
4. **`preserve_side_content_bg` is a general-purpose flag but only used
by the theme picker** — if other popups start using side content with
intentional backgrounds they'll need to opt in explicitly. Not a real
risk today, just a note for future callers.
Fixes#12175
If a user types an npm package name with multiple `@` symbols like `npx
-y @foo/bar@latest`, the TUI currently treats this as though it's
attempting to invoke the file picker.
### What changed
- **Generalized `@` token parsing**
- `current_prefixed_token(...)` now treats `@` as a token start **only
at a whitespace boundary** (or start-of-line).
- If the cursor is on a nested `@` inside an existing
whitespace-delimited token (for example `@scope/pkg@latest`), it keeps
the surrounding token active instead of starting a new token at the
second `@`.
- It also avoids misclassifying mid-word usages like `foo@bar` as an `@`
file token.
- **Enter behavior with file popup**
- If the file-search popup is open but has **no selected match**,
pressing `Enter` now closes the popup and falls through to normal submit
behavior.
- This prevents pasted strings containing `@...` from blocking
submission just because file-search was active with no actionable
selection.
### Testing
I manually built and tested the scenarios involved with the bug report
and related use of `@` mentions to verify no regressions
## Summary
Introduces the initial implementation of Feature::RequestPermissions.
RequestPermissions allows the model to request that a command be run
inside the sandbox, with additional permissions, like writing to a
specific folder. Eventually this will include other rules as well, and
the ability to persist these permissions, but this PR is already quite
large - let's get the core flow working and go from there!

Solves Issue #12453
## Summary
Adds syntax highlighting to the TUI for fenced code blocks in markdown
responses and file diffs, plus a `/theme` command with live preview and
persistent theme selection. Uses syntect (~250 grammars, 32 bundled
themes, ~1 MB binary cost) — the same engine behind `bat`, `delta`, and
`xi-editor`. Includes guardrails for large inputs, graceful fallback to
plain text, and SSH-aware clipboard integration for the `/copy` command.

## Problem
Code blocks in the TUI (markdown responses and file diffs) render
without syntax highlighting, making it hard to scan code at a glance.
Users also have no way to pick a color theme that matches their terminal
aesthetic.
## Mental model
The highlighting system has three layers:
1. **Syntax engine** (`render::highlight`) -- a thin wrapper around
syntect + two-face. It owns a process-global `SyntaxSet` (~250 grammars)
and a `RwLock<Theme>` that can be swapped at runtime. All public entry
points accept `(code, lang)` and return ratatui `Span`/`Line` vectors or
`None` when the language is unrecognized or the input exceeds safety
guardrails.
2. **Rendering consumers** -- `markdown_render` feeds fenced code blocks
through the engine; `diff_render` highlights Add/Delete content as a
whole file and Update hunks per-hunk (preserving parser state across
hunk lines). Both callers fall back to plain unstyled text when the
engine returns `None`.
3. **Theme lifecycle** -- at startup the config's `tui.theme` is
resolved to a syntect `Theme` via `set_theme_override`. At runtime the
`/theme` picker calls `set_syntax_theme` to swap themes live; on cancel
it restores the snapshot taken at open. On confirm it persists `[tui]
theme = "..."` to config.toml.
## Non-goals
- Inline diff highlighting (word-level change detection within a line).
- Semantic / LSP-backed highlighting.
- Theme authoring tooling; users supply standard `.tmTheme` files.
## Tradeoffs

CRLF stripping, style conversion, guardrail enforcement, theme name
mapping exhaustiveness.

guardrail, rename-to-different-extension highlighting, parser state
preservation across hunk lines.
- Unit tests in `theme_picker.rs`: preview rendering (wide + narrow),
dim overlay on deletions, subtitle truncation, cancel-restore, fallback
for unavailable configured theme.
- Unit tests in `list_selection_view.rs`: side layout geometry, stacked
fallback, buffer clearing, cancel/selection-changed callbacks.
- Integration test in `lib.rs`: theme warning uses the final

## Cargo Deny: Unmaintained Dependency Exceptions
This PR adds two `cargo deny` advisory exceptions for transitive
dependencies pulled in by `syntect v5.3.0`:
| Advisory | Crate | Status |
|----------|-------|--------|
| RUSTSEC-2024-0320 | `yaml-rust` | Unmaintained (maintainer
unreachable) |
| RUSTSEC-2025-0141 | `bincode` | Unmaintained (development ceased;
v1.3.3 considered complete) |
**Why this is safe in our usage:**
- Neither advisory describes a known security vulnerability. Both are
"unmaintained" notices only.
- `bincode` is used by syntect to deserialize pre-compiled syntax sets.
Again, these are **static vendored artifacts** baked into the binary at
build time. No user-supplied bincode data is ever deserialized. - Attack
surface is zero for both crates; exploitation would require a
supply-chain compromise of our own build artifacts.
- These exceptions can be removed when syntect migrates to `yaml-rust2`
and drops `bincode`, or when alternative crates are available upstream.
## Problem
Long URLs containing `/` and `-` characters are split across multiple
terminal lines by `textwrap`'s default hyphenation rules. This breaks
terminal link detection: emulators can no longer identify the URL as
clickable, and copy-paste yields a truncated fragment. The issue affects
every view that renders user or agent text — exec output, history cells,
markdown, the app-link setup screen, and the VT100 scrollback path.
A secondary bug compounds the first: `desired_height()` calculations
count logical lines rather than viewport rows. When a URL overflows its
line and wraps visually, the height budget is too small, causing content
to clip or leave gaps.
Here is how the complete URL is interpreted by the terminal before
(first line only) and after (complete URL):
| Before | After |

/> |
## Mental model
The TUI now treats URL-like tokens as atomic units that must never be
split by the wrapping engine. Every call site that previously used
`word_wrap_*` has been migrated to `adaptive_wrap_*`, which inspects
each line for URL-like tokens and switches wrapping strategy
accordingly:
- **Non-URL lines** follow the existing `textwrap` path unchanged (word
boundaries, optional indentation, hyphenation).
- **URL-only lines** (with at most decorative markers like `│`, `-`,
`1.`) are emitted unwrapped so terminal link detection works; ratatui's
`Wrap { trim: false }` handles the final character wrap at render time.
- **Mixed lines** (URL + substantive non-URL prose) flow through
`adaptive_wrap_line` so prose wraps naturally at word boundaries while
URL tokens remain unsplit.
Height measurement everywhere now delegates to
`Paragraph::line_count(width)`, which accounts for the visual row cost
of overflowed lines. This single source of truth replaces ad-hoc line
counting in individual cells.
For terminal scrollback (the VT100 path that prints history when the TUI
exits), URL-only lines are emitted unwrapped so the terminal's own link
detector can find them. Mixed URL+prose lines use adaptive wrapping so
surrounding text wraps naturally. Continuation rows are pre-cleared to
avoid stale content artifacts.
## Non-goals
- Full RFC 3986 URL parsing. The detector is a conservative heuristic
that covers `scheme://host`, bare domains (`example.com/path`),
`localhost:port`, and IPv4 hosts. IPv6 (`[::1]:8080`) and exotic schemes
are intentionally excluded from v1.
- Changing wrapping behavior for non-URL content.
- Reflowing or reformatting existing terminal scrollback on resize.
## Tradeoffs
| Decision | Upside | Downside |
|----------|--------|----------|
| Heuristic URL detection vs. full parser | Fast, zero-alloc on the hot
path; conservative enough to reject file paths like `src/main.rs` |
False negatives on obscure URL formats (they get split as before) |
| Adaptive (three-path) wrapping | Non-URL lines are untouched — no
behavior change, no perf cost; mixed lines wrap prose naturally while
preserving URLs | Three wrapping strategies to reason about when
debugging layout |
| Row-based truncation with line-unit ellipsis | Accurate viewport
budget; stable "N lines omitted" count across terminal widths |
`truncate_lines_middle` is more complex (must compute per-line row cost)
|
| Unwrapped URL-only lines in scrollback | Terminal emulators detect
clickable links; copy-paste gets the full URL | TUI and scrollback
formatting diverge for URL-only lines |
| Default `desired_height` via `Paragraph::line_count` | DRY — most
cells inherit correct measurement | Cells with custom layout must
remember to override |

## Observability
- **Ellipsis message** in truncated exec output reports omitted count in
logical lines (stable across resize) rather than viewport rows
(fluctuates).
- URL detection is deterministic and stateless — no hidden caching or
memoization to go stale.
- Height mismatch bugs surface immediately as visual clipping or gaps;
the `Paragraph::line_count` path is the same code ratatui uses at render
time, so measurement and rendering cannot diverge.
## Tests
26 new unit tests across 7 files, covering:
- **URL integrity**: assert a URL-like token appears on exactly one
rendered line (not split across two).
- **Height accuracy**: compare `desired_height()` against
`Paragraph::line_count()` for URL-containing content.
- **Row-aware truncation**: verify ellipsis counts logical lines and
output fits within the row budget.
- **Scrollback rendering**: VT100 backend tests confirm prefix and URL
land on the same row; continuation rows are cleared; mixed URL+prose
lines wrap prose while preserving URL tokens.
- **Mixed URL+prose detection**: `line_has_mixed_url_and_non_url_tokens`
correctly distinguishes lines with substantive non-URL text from lines
with only decorative markers alongside a URL.
- **Heuristic correctness**: positive matches (`https://...`,
`example.com/path`, `localhost:3000/api`, `192.168.1.1:8080/health`) and
negative matches (`src/main.rs`, `foo/bar`, `hello-world`).
## Risks and open items
1. **URL-like tokens in code output** (e.g. `example.com/api` inside a
JSON blob) will trigger URL-preserving wrap on that line. This is
acceptable — the worst case is a slightly wider line, not broken output.
2. **Very long non-URL tokens on a URL line** can only break at
character boundaries (the custom splitter emits all char indices for
non-URL words). On extremely narrow terminals this could overflow, but
narrow terminals already degrade gracefully.
3. **No IPv6 support** — `[::1]:8080/path` will be treated as a non-URL
and may get split. Can be added later without API changes.
Fixes#5457
## Why
`codex-rs/core/src/lib.rs` re-exported a broad set of types and modules
from `codex-protocol` and `codex-shell-command`. That made it easy for
workspace crates to import those APIs through `codex-core`, which in
turn hides dependency edges and makes it harder to reduce compile-time
coupling over time.
This change removes those public re-exports so call sites must import
from the source crates directly. Even when a crate still depends on
`codex-core` today, this makes dependency boundaries explicit and
unblocks future work to drop `codex-core` dependencies where possible.
## What Changed
- Removed public re-exports from `codex-rs/core/src/lib.rs` for:
- `codex_protocol::protocol` and related protocol/model types (including
`InitialHistory`)
- `codex_protocol::config_types` (`protocol_config_types`)
- `codex_shell_command::{bash, is_dangerous_command, is_safe_command,
parse_command, powershell}`
- Migrated workspace Rust call sites to import directly from:
- `codex_protocol::protocol`
- `codex_protocol::config_types`
- `codex_protocol::models`
- `codex_shell_command`
- Added explicit `Cargo.toml` dependencies (`codex-protocol` /
`codex-shell-command`) in crates that now import those crates directly.
- Kept `codex-core` internal modules compiling by using `pub(crate)`
aliases in `core/src/lib.rs` (internal-only, not part of the public
API).
- Updated the two utility crates that can already drop a `codex-core`
dependency edge entirely:
- `codex-utils-approval-presets`
- `codex-utils-cli`
## Verification
- `cargo test -p codex-utils-approval-presets`
- `cargo test -p codex-utils-cli`
- `cargo check --workspace --all-targets`
- `just clippy`
## Problem
The TUI's "edit queued message" shortcut (Alt+Up) is either silently
swallowed or recognized as another key combination by Apple Terminal,
Warp, and VSCode's integrated terminal on macOS. Users in those
environments see the hint but pressing the keys does nothing.
## Mental model
When a model turn is in progress the user can still type follow-up
messages. These are queued and displayed below the composer with a hint
line showing how to pop the most recent one back into the editor. The
hint text and the actual key handler must agree on which shortcut is
used, and that shortcut must actually reach the TUI—i.e. it must not be
intercepted by the host terminal.
Three terminals are known to intercept Alt+Up: Apple Terminal (remaps it
to cursor movement), Warp (consumes it for its own command palette), and
VSCode (maps it to "move line up"). For these we use Shift+Left instead.

## Non-goals
- Making the binding user-configurable at runtime (deferred to a broader
keybinding-config effort).
- Remapping any other shortcuts that might be terminal-specific.
## Tradeoffs
- **Exhaustive match instead of a wildcard default.** The
`queued_message_edit_binding_for_terminal` function explicitly lists
every `TerminalName` variant. This is intentional: adding a new terminal
to the enum will produce a compile error, forcing the author to decide
which binding that terminal should use.
- **Binding lives on `ChatWidget`, hint lives on `QueuedUserMessages`.**
The key event handler that actually acts on the press is in
`ChatWidget`, but the rendered hint text is inside `QueuedUserMessages`.
These are kept in sync by `ChatWidget` calling
`bottom_pane.set_queued_message_edit_binding(self.queued_message_edit_binding)`
during construction. A mismatch would show the wrong hint but would not
lose data.

No new crates or public API surface. The only cross-crate dependency
added is `codex_core::terminal::{TerminalName, terminal_info}`, which
already existed for telemetry.
## Observability
No new logging. Terminal detection already emits a `tracing::debug!` log
line at startup with the detected terminal name, which is sufficient to
diagnose binding mismatches.
## Tests
- Existing `alt_up_edits_most_recent_queued_message` test is preserved
and explicitly sets the Alt+Up binding to isolate from the host
terminal.
- New parameterized async tests verify Shift+Left works for Apple
Terminal, Warp, and VSCode.
- A sync unit test asserts the mapping table covers the three special
terminals (Shift+Left) and that iTerm2 still gets Alt+Up.
Fixes#4490
## Summary
Simplify network approvals by removing per-attempt proxy correlation and
moving to session-level approval dedupe keyed by (host, protocol, port).
Instead of encoding attempt IDs into proxy credentials/URLs, we now
treat approvals as a destination policy decision.
- Concurrent calls to the same destination share one approval prompt.
- Different destinations (or same host on different ports) get separate
prompts.
- Allow once approves the current queued request group only.
- Allow for session caches that (host, protocol, port) and auto-allows
future matching requests.
- Never policy continues to deny without prompting.
Example:
- 3 calls:
- a.com (line 443)
- b.com (line 443)
- a.com (line 443)
=> 2 prompts total (a, b), second a waits on the first decision.
- a.com:80 is treated separately from a.com line 443
## Testing
- `just fmt` (in `codex-rs`)
- `cargo test -p codex-core tools::network_approval::tests`
- `cargo test -p codex-core` (unit tests pass; existing
integration-suite failures remain in this environment)
Summary
- filter command popup builtins to remove any `/debug*` entries so they
stay usable but are not listed
- added regression tests to ensure the popup hides debug commands while
dispatch still resolves them
### Description
#### Summary
Adds the TUI UX layer for structured network approvals
#### What changed
- Updated approval overlay to display network-specific approval context
(host/protocol).
- Added/updated TUI wiring so approval prompts show correct network
messaging.
- Added tests covering the new approval overlay behavior.
#### Why
Core orchestration can now request structured network approvals; this
ensures users see clear, contextual prompts in the TUI.
#### Notes
- UX behavior activates only when network approval context is present.

## Summary
This PR makes app-server-provided image URLs first-class attachments in
TUI, so they survive resume/backtrack/history recall and are resubmitted
correctly.

In both history and composer, remote images are rendered as normal
`[Image #N]` placeholders, with numbering unified with local images.
## What changed
- Plumb remote image URLs through TUI message state:
- `UserHistoryCell`
- `BacktrackSelection`
- `ChatComposerHistory::HistoryEntry`
- `ChatWidget::UserMessage`
- Show remote images as placeholder rows inside the composer box (above
textarea), and in history cells.
- Support keyboard selection/deletion for remote image rows in composer
(`Up`/`Down`, `Delete`/`Backspace`).
- Preserve remote-image-only turns in local composer history (Up/Down
recall), including restore after backtrack.
- Ensure submit/queue/backtrack resubmit include remote images in model
input (`UserInput::Image`), and keep request shape stable for
remote-image-only turns.
- Keep image numbering contiguous across remote + local images:
- remote images occupy `[Image #1]..[Image #M]`
- local images start at `[Image #M+1]`
- deletion renumbers consistently.
- In protocol conversion, increment shared image index for remote images
too, so mixed remote/local image tags stay in a single sequence.
- Simplify restore logic to trust in-memory attachment order (no
placeholder-number parsing path).
- Backtrack/replay rollback handling now queues trims through
`AppEvent::ApplyThreadRollback` and syncs transcript overlay/deferred
lines after trims, so overlay/transcript state stays consistent.
- Trim trailing blank rendered lines from user history rendering to
avoid oversized blank padding.
## Docs + tests
- Updated: `docs/tui-chat-composer.md` (remote image flow,
selection/deletion, numbering offsets)
- Added/updated tests across `tui/src/chatwidget/tests.rs`,
`tui/src/app.rs`, `tui/src/app_backtrack.rs`, `tui/src/history_cell.rs`,
and `tui/src/bottom_pane/chat_composer.rs`
- Added snapshot coverage for remote image composer states, including
deleting the first of two remote images.
## Validation
- `just fmt`
- `cargo test -p codex-tui`

## Summary
- Increases `PASTE_BURST_CHAR_INTERVAL` from 8ms to 30ms on Windows to
fix multi-line paste issues in VS Code integrated terminal
- Follows existing pattern of platform-specific timing (like
`PASTE_BURST_ACTIVE_IDLE_TIMEOUT`)
## Problem
When pasting multi-line text in Codex CLI on Windows (especially VS Code
integrated terminal), only the first portion is captured before
auto-submit. The rest arrives as a separate message.
**Root cause**: VS Code's terminal emulation adds latency (~10-15ms per
character) between key events. The 8ms `PASTE_BURST_CHAR_INTERVAL`
threshold is too tight - characters arrive slower than expected, so
burst detection fails and Enter submits instead of inserting a newline.
## Solution
Use Windows-specific timing (30ms) for `PASTE_BURST_CHAR_INTERVAL`,
following the same pattern already used for
`PASTE_BURST_ACTIVE_IDLE_TIMEOUT` (60ms on Windows vs 8ms on Unix).
30ms is still fast enough to distinguish paste from typing (humans type
~200ms between keystrokes).
## Test plan
- [x] All existing paste_burst tests pass
- [ ] Test multi-line paste in VS Code integrated PowerShell on Windows
- [ ] Test multi-line paste in standalone Windows PowerShell
- [ ] Verify no regression on macOS/Linux

We are removing feature-gated shared crates from the `codex-rs`
workspace. `codex-common` grouped several unrelated utilities behind
`[features]`, which made dependency boundaries harder to reason about
and worked against the ongoing effort to eliminate feature flags from
workspace crates.
Splitting these utilities into dedicated crates under `utils/` aligns
this area with existing workspace structure and keeps each dependency
explicit at the crate boundary.
## What changed
- Removed `codex-rs/common` (`codex-common`) from workspace members and
workspace dependencies.
- Added six new utility crates under `codex-rs/utils/`:
- `codex-utils-cli`
- `codex-utils-elapsed`
- `codex-utils-sandbox-summary`
- `codex-utils-approval-presets`
- `codex-utils-oss`
- `codex-utils-fuzzy-match`
- Migrated the corresponding modules out of `codex-common` into these
crates (with tests), and added matching `BUILD.bazel` targets.
- Updated direct consumers to use the new crates instead of
`codex-common`:
- `codex-rs/cli`
- `codex-rs/tui`
- `codex-rs/exec`
- `codex-rs/app-server`
- `codex-rs/mcp-server`
- `codex-rs/chatgpt`
- `codex-rs/cloud-tasks`
- Updated workspace lockfile entries to reflect the new dependency graph
and removal of `codex-common`.
## Summary
- keep cursor at end-of-line after Up/Down history recall
- allow continued history navigation when recalled text cursor is at
start or end boundary
- add regression tests and document the history cursor contract in
composer docs
## Testing
- just fmt
- cargo test -p codex-tui --lib
history_navigation_leaves_cursor_at_end_of_line
- cargo test -p codex-tui --lib
should_handle_navigation_when_cursor_is_at_line_boundaries
- cargo test -p codex-tui *(fails in existing integration test
`suite::no_panic_on_startup::malformed_rules_should_not_panic` because
`target/debug/codex` is not present in this environment)*
When steer mode is enabled, Tab used to only queue while a task was
running and otherwise did nothing. Treat Tab as an immediate submit when
no task is running so input isn't dropped when the inflight turn ends
mid-typing.
Adds a regression test and updates docs/tooltips.
