## Summary

Adds a new permission UI for terminal pipeline commands (e.g. `cargo
test | tail`) that lets users selectively always-allow individual
commands in the pipeline, rather than only offering a blanket
always-allow for the first command.

## Context

Previously we were very eagerly dropping threads from memory. However,
reloading threads has a cost:
- For our agent, we have to replay events, which is lossy
- It's slower for external agents
- Some agents don't support reloading

So we keep the most recent 5 idle threads (or all threads who can't be
reloaded) and clean up our list after every insertion.

We previously removed all cwd from this hoping to have a global process
shared, but it doesn't work for remote projects. Since we're at the
project boundary anyway, we might as well start it up in a similar spot
as a new thread.

Closes ZED-5DE

Release Notes:

- N/A or Added/Fixed/Improved ...

## Context

Fixes the visual selection update in `TextDiffView::open` to properly
convert between buffer-local and multibuffer coordinates using
`buffer_point_to_anchor`. Previously, raw multibuffer Points were used
directly for line expansion, which produced incorrect regions when
expanded deleted diff hunks shifted multibuffer row numbers.

This provides a single unified code path for both singleton and
non-singleton multibuffers, as suggested in [#51457 review
feedback](https://github.com/zed-industries/zed/pull/51457#issuecomment-4091134303).

Follow-up to #51457.

## How to Review

Small PR - all changes are in `crates/git_ui/src/text_diff_view.rs`.
Focus on:

- `open()`: The visual selection update block now uses
`buffer_point_to_anchor` + `to_point` instead of raw multibuffer
coordinate math
- No more assumption that multibuffer Points == buffer-local Points
- Existing tests validate both singleton and non-singleton multibuffer
paths

Release Notes:

## Context

This PR fixes one of the issues in #51905, where model outputs are full
of errant `\` characters.

heres the problem: As the response is streamed back to zed, we
accumulate the message chunks and and need to convert those chunks to
valid json, to do that we use `partial_json_fixer::fix_json`, when the
last character of a chunk is `\`, the `fix_json` has to escape that
backslash, because its inside of a string (if it isn't, its invalid json
and the tool call will crash) and other wise you would end up escaping
the end `"` and everything would be messed up.

why is this a problem for zed:
T_0 is the output at some step.
T_1 is the output at the next step.

the `fix_json` system is meant to be used by replacing T_0 with T_1,
however in the editor, replacing the entirety of T_0 with T_1 would be
slow/cause flickering/etc.. so we calculate the difference between T_0
and T_1 and just add it to the current buffer state. So when a chunk
ends on `\`, we end up with something like `... end of line\\"}` at the
end of T_0,
in T_1, this becomes `... end of line\n ...`. then when we add the new
chunk from T_1, it just picks up after the \n because its tracking the
length to manage the deltas.


## How to Review

utils.rs:
fix_streamed_json => remove trailing backslashes from incoming json
streams so that `partial_json_fixer::fix_json` doesn't try to escape
them.
other files: call fix_streamed_json before passing to `serde_json`

I had claude write a bunch of tests while I was working on the fix,
which I have kept in for now, but the end functionality of
fix_streamed_json is really simple now, so maybe these arent really
needed.

also happen if there are no search matches.
- Improved archive view keyboard nav and design. Not using the ListItem
here anymore so as to avoid confusing hover and active states.
- Move archive and open folder buttons to the bottom of the sidebar.
- Add a new flavor of the recent projects for the sidebar that only
serves as a way to _add_ projects.
- Add the ability to add (and remove) folders to a given project group

Release Notes:

When a git worktree is in a detached HEAD state (e.g. after `git
checkout --detach`), the workspace for that worktree would disappear
from the sidebar UI, and if the workspace was currently open your UI
would just disappear.

This happened because `parse_worktrees_from_str` silently dropped any
worktree entries without a `branch` line in the porcelain output, which
cascaded through the `linked_worktrees` list and caused
`prune_stale_worktree_workspaces` to remove the workspace.

This PR:
- Makes `Worktree::ref_name` an `Option<SharedString>` so detached
worktrees can be represented
- Renames `Worktree::branch()` to `Worktree::display_name()`, which
returns the branch name when available or the short SHA as a fallback
(mirroring how the title bar already handles detached HEAD for
repositories)
- Updates `parse_worktrees_from_str` to include detached and bare
worktree entries instead of dropping them
- Filters detached worktrees out of the worktree picker UI, preserving
the existing product decision to only show branch-based worktrees there

The line wrapper's `is_word_char` function included the ASCII apostrophe
(U+0027) but not the typographic right single quotation mark `'`
(U+2019) or left single quotation mark `'` (U+2018). When Markdown
rendering produces curly quotes, words like `won't` were being split at
the apostrophe during line wrapping, producing `won` at the end of one
line and `'t` at the start of the next.

This adds both typographic quote characters to `is_word_char` so they
are treated the same as the ASCII apostrophe.

Release Notes:

- Fixed line wrapping splitting words at typographic apostrophes (e.g.
"won't" breaking as "won" / "'t").

## Context

Fork PRs receive a read-only `GITHUB_TOKEN`, causing 403 errors on all
label and comment writes
([example](https://github.com/zed-industries/zed/pull/51878)). This
splits the single workflow into two:

- **pr-size-check.yml** (`pull_request`): computes size and guided tour
detection, uploads a JSON artifact — read-only, works for forks
- **pr-size-label.yml** (`workflow_run`): downloads the artifact,
applies labels and comments — runs on the base repo with full write
access

### Security

- Artifact treated as untrusted data: fields are cast and validated
(`Number()`, `String()` + prefix check, `Boolean()`) before use
- No artifact content is executed or interpolated into shell
- Missing artifact handled gracefully (steps skip via output flag)

### Also included

- Structural guided tour detection: extracts "How to Review" section,
strips HTML comment placeholders, checks for actual author content
(fixes false positive in #51957)
- Softer confirmation: "appears to include guidance"

Tested locally end-to-end against 4 real PRs
(XL/small/medium/false-positive).

## How to Review

1. `pr-size-check.yml` — the compute half. Compare against the previous
version: all write operations removed, artifact upload added at the end.
2. `pr-size-label.yml` — new file. Download artifact, validate, apply
labels/comments. Same label logic as before, just in a `workflow_run`
context.

Closes #51865 

The Tool Permissions and Edit Prediction Providers pages have settings
that do not conform very well to the usual setup, because of this they
are specially defined in .../settings_ui/src/pages . Due to this setup,
they do not benefit from the same automatic responsive setup as the
other parts of the settings ui. This was causing issues w/ narrow
windows, where fields and text were extending past the side of the
window or just not displaying.
All that was needed to fix it was some tweaks to the structure and css
of those pages, and its smooth sailing. Maybe in the future
`render_settings_item` can be made broader and support these use cases
as well so this doesn't have to be handled manually.

## Context

Follow-up to #51964. The previous fix (stripping HTML comments) still
had a false positive: the `## How to Review` heading itself matched the
`how to review` alternative in the regex. Every PR using the template
would trigger the "guided tour detected" message.

Replace the regex with structural detection: extract the "How to Review"
section, strip template placeholders, and check if the author actually
wrote content there. Also softens the confirmation message to "appears
to include guidance."

## How to Review

## Context

The permissions ceiling bug (fixed in #51948) left two open PRs (#51897,
#50372) with failed `check-size` runs. The Check Runs API requires
GitHub App auth, so we can't post passing checks from the CLI — it needs
to run inside Actions with `checks: write`.

This adds a `workflow_dispatch` workflow that takes comma-separated PR
numbers, computes sizes, applies labels, and posts passing check runs.
Delete after use.

## How to Review

- Single file: `.github/workflows/fix-size-check.yml`
- Uses the same size logic and ignored patterns as `pr-size-check.yml`
- Input is `pr_numbers` (comma-separated integers), accessed via JS API,
not shell interpolation

Closes #47111

Release Notes:

- Fixed an issue where using `@fetch` in the agent panel would break if
URL contained an `@` character

Co-authored-by: Marshall Bowers <git@maxdeviant.com>

When typing with the macOS Accessibility Keyboard and clicking a word
completion suggestion, text was corrupted in several ways.

macOS sends `insertText:replacementRange:` when a completion is
selected. The replacement range was passed to
`selection_replacement_ranges` using the wrong offset type, causing
incorrect delta calculation for multi-cursor scenarios. Additionally,
`backspace` was called unconditionally even when the replacement range
was empty (as with the trailing space the Accessibility Keyboard
appends), deleting the last character of every completed word. Finally,
an empty replacement range in a multi-cursor context carries a stale
cursor position from macOS's single-cursor view of the buffer, so it is
now ignored and text is inserted at each cursor's actual position
instead.

Closes #38052

Release Notes:

- Fixed text corruption when using macOS Accessibility Keyboard word
completion.

This PR adjusts the logic that was added in #45166 to just apply to the
specific case of interacting with the command palette in Vim and Helix
modes (hereafter referred to collectively as "Vim mode").

In that PR, we would suppress the auto-save on focus change for _any_
modal in the workspace, regardless of whether we were actually in Vim
mode or not. This would cause issues where moving between files some
other way—such as the tab switcher or the file finder—would cause the
buffers to never be saved.

We now only suppress the auto-save on focus loss behavior when in Vim
mode and the active modal is the command palette. In all other cases, we
save the file.

Closes https://github.com/zed-industries/zed/issues/47968.

Supersedes https://github.com/zed-industries/zed/pull/51801 and
https://github.com/zed-industries/zed/pull/51802.

Note: the way we are identifying the active modal as the command palette
isn't the best, but @bennetbo and I didn't have any other cleaner
solutions. It's a bit tricky, as the logic lives in the `workspace`,
which isn't able to know about the `CommandPalette` due to
`command_palette` depending on `workspace`. There may be some other way
we could achieve this with more indirection, but it's unclear whether it
would be worth it at this time.

Release Notes:

- Changed `{ "autosave": "on_focus_change" }` to now always save on
focus loss, except for when activating the command palette when in
Vim/Helix mode.

## Context

The PR size check workflow has been failing with `403 Resource not
accessible by integration` on every run
([example](https://github.com/zed-industries/zed/actions/runs/23281894554/job/67698634490)).
The root cause is a workflow-level `permissions` block that set a
read-only ceiling, silently preventing the job-level `issues: write` and
`pull-requests: write` grants from taking effect.

This also adds an idempotency improvement: when a new push doesn't
change the PR's size bracket, the workflow now skips the label
remove/re-add cycle, eliminating unnecessary timeline noise.

## How to Review

- Focus on `.github/workflows/pr-size-check.yml` — that's the only file
changed
- Lines 17-23: workflow-level `permissions` block removed, job-level
retained
- Lines 81-112: new `alreadyCorrect` check wraps the label mutation
block

- Agent: Fix rendering of filenames in edit tool header

Closes #51740 

The multi-line cursor expansion operates off of byte offsets, instead of
character offsets, so multi-byte characters like the umlaut cause the
multi-line cursors to be weirdly offset. To fix we just convert the
expansion logic to rely on utf16 characters instead of bytes.

Summary
Add a new grid_cols_max_content GPUI styling API that uses minmax(0,
max-content) for grid column sizing. This allows columns to
automatically size based on their content width while remaining
responsive when the container shrinks.

Applied the fix to both markdown preview (markdown_renderer.rs) and
agent panel (markdown.rs) table rendering. Table borders now wrap
tightly around content instead of stretching to full container width.

Fixes #50044

Approach
A new grid_cols_max_content API is added (as discussed with
@MikaylaMaki):

style.rs — New grid_cols_max_content: Option<u16> field
styled.rs — New .grid_cols_max_content(cols) builder method
taffy.rs — New to_grid_repeat_max_content() using minmax(0, max-content)
markdown_renderer.rs — Swapped .grid_cols() → .grid_cols_max_content(),
moved border to grid div, wrapped in v_flex().items_start() so border
hugs content
markdown.rs — Applied same fix for agent panel tables:
grid_cols_max_content, border on grid div, wrapped in
div().flex().flex_col().items_start() container
Screenshots

Closes #48917

## Summary
- Stop sending `context.only` for generic `textDocument/codeAction`
requests.
 - Keep explicit kind filtered requests unchanged.
- Add regression coverage for generic code action requests so actions
like `source.addTest` remain visible.

## Root Cause
`GetCodeActions::to_lsp` populated `context.only` even when the caller
requested all code actions (`kinds == None`). That turned the normal
code actions menu into a filtered request. With `gopls`, this filtered
out `source.addTest`, so `Add test for ...` never appeared.

## Verification
 - `cargo fmt --all -- --check`
 - `./script/clippy -p project`
 - `cargo nextest run -p project --no-fail-fast --no-tests=warn`
- `cargo test -p editor
editor_tests::test_organize_imports_manual_trigger -- --exact`
- `cargo test -p editor
editor_tests::test_context_menus_hide_hover_popover -- --exact`

## Manual Testing
- Repro'd the protocol level behavior against `gopls`: unfiltered
requests return `source.addTest`, filtered requests excluding it do not.
 - Opened `zed_guild/testing_projects/act/pkg/artifactcache/handler.go`
 - Triggered `Show Code Actions` on `StartHandler`
 - Confirmed `Add test for StartHandler` appears


Release Notes:

- Fixed Go `gopls` code actions so `Add test for ...` appears in the
generic code actions menu.

Used only for the sign in callback. I've made sure it still works as
expected with a local build.

Release Notes:

- N/A

## Context

I have a project with a nested git repo inside a parent repo (separate
`.git` directory, not a submodule). The title bar shows the parent's
branch instead of the nested repo's own branch.

The issue is in `get_repository_for_worktree()` — it iterates
`git_store.repositories()` (an `FxHashMap`) and returns the first
`starts_with` match. Both the parent and nested repo match, and
whichever one FxHashMap iterates first wins. There's no reason it should
be one or the other.

The fix already exists elsewhere in the codebase —
`GitStore::repository_and_path_for_project_path()` at
`git_store.rs:1826` uses `.max_by_key()` to pick the most specific
(longest path) match. This PR applies the same approach to three
functions that have the same problem:

- `TitleBar::get_repository_for_worktree()` — branch display in title
bar
- `resolve_active_repository()` in `git_ui` — repository selection for
the git panel
- `get_branch_for_worktree()` in `recent_projects` — branch display in
the project switcher

Two other locations use a similar `starts_with` pattern
(`effective_active_worktree()` in `title_bar.rs` and worktree selection
in `recent_projects.rs`) but those iterate worktrees against a single
known repo, not repos against a worktree — so first-match and
longest-match give the same result. Left those unchanged.

Closes #7566

## How to Review

All three changes are the same transformation: first-match loop (or
`.find()`) → `.filter().max_by_key()` on path length. The reference is
at `crates/project/src/git_store.rs:1826`.

The primary fix is `get_repository_for_worktree()` in `title_bar.rs`.
The other two are the same pattern.

One difference from the reference: I used `.as_os_str().len()` instead
of `.clone()` for the `max_by_key` key — avoids cloning an `Arc<Path>`
per comparison. Among prefix-related paths (which is all that passes the
filter), the longer path is always the more specific match, so length
comparison is equivalent.

`title_bar` has no existing test infrastructure. Happy to add a test if
you'd like — the setup would follow the pattern in
`test_git_traversal_with_nested_repos`
(`crates/project/tests/integration/git_store.rs`).

```
cargo test -p title_bar -p git_ui -p recent_projects
./script/clippy
```

Render `[x]` and `[ ]` as checkbox widgets when they appear as the sole
content of a markdown table cell. Previously these were displayed as raw
text. List-item checkboxes were already rendered correctly; this extends
the same treatment to table cells.

Fixes #50045.

## What this does

- Table cells containing only `[x]`, `[X]`, or `[ ]` now render as
visual checkboxes instead of plain text
- Both markdown rendering paths are covered: the `markdown` crate (agent
panel, chat) and the `markdown_preview` crate (file preview)
- Checkboxes are display-only, matching the existing list-item checkbox
behavior

## How it works

pulldown-cmark splits `[x]` in table cells into three separate `Text`
events (`[`, `x`, `]`) rather than emitting a `TaskListMarker` event
(which only fires for list items per the GFM spec). The fix operates at
each crate's natural interception point:

- **`markdown` crate**: After all text events for a table cell have been
buffered, `replace_pending_checkbox()` checks the accumulated text
before the cell div is finalized. If it matches the checkbox pattern,
the pending text is replaced with a `Checkbox` widget.
- **`markdown_preview` crate**: In `render_markdown_text()`, text chunks
whose trimmed content matches the checkbox pattern are rendered as
`MarkdownCheckbox` widgets instead of `InteractiveText`.

## Scope

Three files, purely additive:

- `crates/markdown/src/markdown.rs` — `replace_pending_checkbox()` on
builder, called at `TableCell` end
- `crates/markdown_preview/src/markdown_renderer.rs` — checkbox
detection in `render_markdown_text()`
- `crates/markdown_preview/src/markdown_parser.rs` — test only

No changes to parser data models, GPUI, or any shared infrastructure.

## What's not in scope

- **HTML `<input type="checkbox">`** — pulldown-cmark strips these as
raw HTML. Supporting them requires HTML tag parsing, which is a separate
concern.
- **Interactive (click-to-toggle) checkboxes in tables** — table
checkboxes are display-only. List-item checkboxes in Zed support
Cmd+click toggling, but extending that to table cells would require
tracking source ranges across the split parser events, which is a
separate enhancement.

## Follow-up

Table checkbox interactivity (Cmd+click toggle) is straightforward to
add as a follow-up — the source ranges are already available in
`markdown_preview`, and the `markdown` crate would need minor callback
plumbing.

/>

## Test plan

**Unit tests** (2 new):
- `test_table_with_checkboxes` (markdown_preview) — parser delivers
`[x]`/`[ ]` text into table cell structures
- `test_table_checkbox_detection` (markdown) — parser events accumulate
checkbox text in table cells, confirming `replace_pending_checkbox`
detection logic

**Automated**:
- [x] `cargo test -p markdown` — 27 tests pass (26 existing + 1 new)
- [x] `cargo test -p markdown_preview` — 61 tests pass (60 existing + 1
new)

**Manual** (verified against `test-checkbox-table.md`):
- [x] Basic `[x]`/`[ ]` in a status column
- [x] Checkbox-only column alongside text
- [x] Multiple checkbox columns in one table
- [x] Left, center, and right column alignments
- [x] Uppercase `[X]` variant
- [x] Leading/trailing whitespace in cell
- [x] Checkboxes alongside other inline elements (links, bold text)
- [x] Single-column and minimal two-column tables
- [x] Normal table text unaffected by detection
- [x] List checkboxes still render correctly (regression)
- [x] Agent panel: asked agent to output table with checkbox columns

Release Notes:

- Fixed `[x]` and `[ ]` checkboxes not rendering in markdown table cells
(#50045)

Release Notes:

- Support for Native Thinking toggle instead of model variants
