Sometimes github issues are created without following the template, and
if they don't receive the `state:needs triage` label from a template,
it's easy for us to miss them. Well, not anymore, thanks to this new
github workflow.
As an extra measure, the label is also added on reopened issues. All of
this only applies only to actions carried out by people outside of the
staff team.

Right now agent extensions can specify icon paths that point anywhere.
This changes it so that they can only specify icon paths that are
subdirectories of the extension's root dir.

Release Notes:

- Restrict agent server extension icon paths to subdirectories of the
extension's root directory

The default behavior for Vim search with `*` and `#` in normal mode is
to initiate a search and immediately jump to the next or previous match
respectively.

This behavior can be annoying, so Vim has many plugins to address this
specifically:

- [vim-asterisk](https://github.com/haya14busa/vim-asterisk)
-
[vim-SearchHighlighting](https://github.com/inkarkat/vim-SearchHighlighting)
- [vim-tranquille](https://github.com/RRethy/vim-tranquille)

This PR tries to emulate this behavior natively keeping up with Zed's
sane defaults and deviating from vanilla Vim when it makes sense.


Release Notes:

- Vim: `*` and `#` search doesn't jump immediately to next / previous
search.

This builds on https://github.com/zed-industries/zed/pull/46112 (which
should be merged first) and adds the permission evaluation logic and
integrates it with the terminal tool as part of the tool permissions
feature. This is a separate PR for [stacked
diffs](https://newsletter.pragmaticengineer.com/p/stacked-diffs) to make
review easier.

## Changes

- **Add `tool_permissions.rs`** with `decide_permission()` function that
implements:
  - `deny > confirm > allow` precedence hierarchy (security-critical)
  - Case-sensitive and case-insensitive regex matching
  - Integration with existing `always_allow_tool_actions` setting
  - Comprehensive unit tests (15 tests)

- **Integrate with terminal tool**:
  - Commands matching deny rules are blocked immediately with an error
  - Commands matching allow rules proceed without confirmation dialog
  - Commands requiring confirmation show the dialog as before
  - Added integration tests for deny and allow rule scenarios

When focus is on the conversation part of the agent panel (not the
message editor), pressing Escape now interrupts the running thread.
Previously, Escape only worked when the message editor had focus.

Release Notes:

- Pressing Esc when the agent panel is focused now interrupts the
running thread even if the text input box is not specifically focused.

Implements visual tests for breakpoint hover states in the editor gutter
with three states:
1. **No hover** - just line numbers
2. **Hover with indicator** - blue circle appears next to the line
3. **Hover with tooltip** - shows 'Set breakpoint' with F9 keybinding

- Added `VisualTestPlatform` that combines real Mac rendering with
controllable `TestDispatcher` for deterministic task scheduling and time
control
- Added `VisualTestAppContext::with_asset_source()` to enable SVG icon
rendering in visual tests (uses real Assets instead of empty source)
- Added F9 keybinding for ToggleBreakpoint so tooltip shows the
keybinding
- Removed debug `eprintln!` statements from editor, element, svg, and
window

The `VisualTestPlatform` enables `advance_clock()` which is essential
for testing time-based behaviors like tooltip delays. Without
deterministic time control, tests for hover states and tooltips would be
flaky.

This PR adds some clean up to the worktree picker: making sure that
worktree names render just one line, even when they might have multiple
lines (that was making each line item break for me), removing
superfluous icons, and making the footer controls more consistent with
the branch picker, where the buttons change to "Create..." if you're in
a state where the only match is the one to create a new worktree.


https://github.com/user-attachments/assets/e63aa8c9-b5a0-443d-a2ab-7759daed10d1

Release Notes:

- Git: Fixed some UI bugs in the worktree picker as well as improved the
UX for creating worktrees based off of the current or default branch.

I really enjoyed this feature in Claude Code. Helps me get a sense of
how effortful something is.

Release Notes:

- Added a "show_turn_stats" setting, default to false, that shows the
timer and the number of tokens down.

This makes running `predict` with the teacher model much faster, when
there are many examples.

## **Summary**
This notification is related to the use of specific values for the
region input field when calling AWS services. An actor with access to
the environment in which the SDK is used could set the region input
field to an invalid value.

A defense-in-depth enhancement has been implemented in the AWS SDK for
Rust. This enhancement validates that a region used to construct an
endpoint URL is a valid host label. The change was released on November
6, 2025. This advisory is informational to help customers understand
their responsibilities regarding configuration security.

## **Impact**
Customer applications could be configured to improperly route AWS API
calls to non-existent or non-AWS hosts. While the SDK was functioning
safely within the requirements of the shared responsibility model,
additional safeguards have been added to support secure customer
implementations.

**Impacted versions**: All versions prior to [November 6, 2025
release](https://redirect.github.com/awslabs/aws-sdk-rust/releases/tag/release-2025-11-06)

## **Patches**
On November 6, 2025, an enhancement [1] was made to the AWS SDK for Rust
release, which validates the formatting of a region, providing
additional safeguards.

## **Workarounds**
No workarounds are needed, but as always developers should ensure that
their application is following security best practices:
- Implement proper input validation in your application code
- Update to the latest AWS SDK for Rust release on a regular basis
- Follow AWS security best practices [2] for SDK configuration

Tackling this as I noticed a bug in the agent panel where the button to
delete a thread, which appeared only on hover, stopped showing up. PRs
#43324 and #45437 fixed stuff in applying hover styles through
`.hover()` but broke the `.on_hover()` callback. Problem was that both
methods were sharing the same `element_state.hover_state` but running at
different phases. The solution here was to add a new independent state
field for the hover listener (`hover_listener_state`) while the hover
style method keeps using `hover_state`.

Release Notes:

- Agent: Fixed a bug where the button to delete a thread stopped showing
up.

This PR removes the const generics limitation from the data table
component, enabling tables with a dynamic number of columns determined
at runtime.

**Context:**  
This is the next infrastructure step split out from the [original CSV
preview draft PR](https://github.com/zed-industries/zed/pull/44344). The
draft PR remains open as a reference and will continue to be decomposed
into smaller, reviewable pieces.

**Details:**  
- Introduces a `TableRow` newtype to enforce column count invariants at
runtime, replacing the previous const generic approach. It's api surface
is larger than is currently used, as it's planned to be used in CSV
feature itself.
- Refactors the data table and all usages (including the keymap editor)
to work with runtime column counts.
- This change is foundational for supporting CSV preview and other
features that require flexible, dynamic tables.
- Performance impact has not been formally measured, but there is no
noticeable slowdown in practice.

This happens because `action_log` does updates on `Entity<Buffer>` which
is a current editor's buffer, tracked, and updated by agent output (acp

When a recorded action moves focus away from the editor (e.g.,
`buffer_search::Deploy`), the `EndRepeat` action handler is not invoked
because is node is no longer on the dispatch path. This left
`dot_replaying` set to `true`, causing subsequent repeats to malfunction
and the `VimGlobals.pre_count` value to never be reset.

Reset `dot_replaying` as a fail-safe when the replayer exhausts its
action queue, ensuring the state is always cleaned up regardless of
whether `EndRepeat` was handled.

- Fixed vim repeat (`.`) breaking when the recorded action moves focus

The `vim` crate's tests depend on `git_ui`, which transitively depends
on `recent_projects` with `test-support` enabled. This causes
`recent_projects` to include RemoteConnectionOptions::Mock` variant
handling. However, `git_ui` was not enabling its `test-support` feature,
causing compilation failures when the Mock variant was expected but not
available.

This commit enables the `test-support` feature for both `git_ui` and
`title_bar` dev-dependencies in the `vim` crate, ensuring the Mock
variant is consistently available during testing.

When the user presses Esc or the Stop button to interrupt a thread,
terminal tools now capture their output and include it in the tool
result. This allows the model to see what was happening in the terminal
when the user interrupted, so it can answer questions about the output.

## Changes

- `Thread::cancel()` now returns a `Task` that waits for tools to
respond to cancellation before flushing pending messages
- Terminal tool uses `select!` to detect cancellation signal and
immediately kills the terminal and captures output
- `run_turn_internal` uses `select!` to break out of event loop on
cancel
- Added test for terminal tool cancellation output capture

This is a follow-up to #46218 which added similar functionality for the
"Stop" button on individual terminal tool cards.

Release Notes:

- Interrupting the agent now captures terminal output so the model can
see what was running when you stopped it

Release Notes:

- The inline assistant now has the ability to display messages and will
be less likely to insert non-code text.

Adds a new `ep split` command that splits JSONL datasets into multiple
output files with stratification by `repository_url` when present.

Example usage:
