Closes #49055

**Heads up**: This might be a naïve solution. I ran into the issue after
merging latest main into
https://github.com/zed-industries/zed/pull/48896, and confirming that it
was unrelated to that PR and incoming from upstream.

Agent one-shot the fix, it works and tests pass. But I'm still wrapping
my head around the changes that led to the bug. I figured the breakage
is bad enough (I couldn't open devcontainers at all) to submit a
possibly naïve fix.

## Fix 

Hoists the `find_devcontainer_configs` call out of `new_dev_container`
and into the call site, where we already have a direct `&mut Workspace`
reference that doesn't go through the entity map. The computed configs
are passed into `new_dev_container` as an argument.

## What was happening

After #48800 ("Re-add MultiWorkspace"), `with_active_or_new_workspace`
nests a `Workspace` entity lease inside a `MultiWorkspace` entity lease.
The `OpenDevContainer` handler was also changed from async to sync in
the same PR, so `RemoteServerProjects::new_dev_container` now runs while
`Workspace` is leased. Inside `new_dev_container`, a
`WeakEntity<Workspace>::read_with` call tries to read `Workspace`
through the entity map, finds it already leased, and panics.

Release Notes:

- Fixed a panic when opening the dev container modal via the
`OpenDevContainer` action.

Closes https://github.com/zed-industries/zed/issues/33430

Two changes:

1. Fix `observe_global_in` to not permanently remove observers when the
window is transiently unavailable (e.g. temporarily taken during a
nested update). Previously this returned false and silently removed the
observer from the subscriber set. Now it checks whether the entity is
actually dropped before removing — if the entity is alive but the window
is just unavailable, it keeps the observer alive.

2. Extend `dock_to_preserve` in `handle_pane_focused` to also preserve
docks whose active panel has focus, not just docks whose panel's inner
pane matches the focused pane. Panels like `AgentPanel` don't implement
`pane()` (only panels like `TerminalPanel` that contain panes do), so
the existing preservation logic never identified the agent panel's dock
as needing protection. This meant that when the agent panel was zoomed
and a center pane received focus (e.g. during macOS window activation
events), `dismiss_zoomed_items_to_reveal` would close the dock, making
the panel disappear unexpectedly.

Closes AI-16

Release Notes:

- Fixed agent panel unexpectedly closing when zoomed and the window
regains focus.

When the agent panel (or any dock panel) is open and
fullscreened/zoomed, switching to a different workspace in the sidebar
and then switching back caused the panel to close. It should remain both
open and zoomed.

The root cause was in `MultiWorkspace::focus_active_workspace()` — it
always focused the center pane of the active workspace. This triggered
`dismiss_zoomed_items_to_reveal(None)`, which closed any zoomed dock
panel (the same behavior as when a user intentionally clicks away from a
zoomed panel).

The fix checks if any dock has a zoomed panel before deciding what to
focus. If a zoomed panel exists, it focuses that panel instead of the
center pane, preventing the dismiss logic from firing.

Closes AI-22

Release Notes:

- Fixed panels losing their fullscreen state when switching between
workspaces.

Closes https://github.com/zed-industries/zed/issues/49060

Release Notes:

- Fixed semantic highlights not cleared when disabled in settings

Remove the `AgentsPanel` (from the `agent_ui_v2` crate) and the utility
pane infrastructure from the codebase.

The Agents Panel was a separate panel gated behind the `agent-v2`
feature flag that was redundant with the existing Agent Panel. Utility
panes were a layout concept (secondary panes next to the editor,
separate from dock panels) whose only consumer was `AgentThreadPane` in
the Agents Panel.

### Changes
- Deleted the entire `agent_ui_v2` crate (`agents_panel.rs`,
`agent_thread_pane.rs`)
- Deleted `workspace/src/utility_pane.rs`
- Removed `UtilityPane`, `UtilityPaneHandle`, `UtilityPanePosition`,
`MinimizePane`, `ClosePane` from `workspace/src/dock.rs`
- Removed all utility pane fields, methods, and render blocks from
`workspace.rs`
- Removed all aside toggle code from `pane.rs` and `pane_group.rs`
- Removed `agents_panel_dock` setting from agent settings and
`default.json`
- Removed all `agent_ui_v2` references from `main.rs`, `zed.rs`, and
Cargo.toml files
- Cleaned up test code in `tool_permissions.rs` and `agent_ui.rs`

Implements automatic label generation for VSCode tasks that don't have
explicit 'label' fields, matching VSCode's behavior.

Changes:
- Made label field optional in VsCodeTaskDefinition deserialization
- Implemented custom deserializer to auto-generate labels:
  - npm tasks: 'npm: {script}' (e.g., 'npm: start')
  - shell tasks: first word of command (e.g., 'echo')
  - gulp tasks: 'gulp: {task}' (e.g., 'gulp: build')
  - fallback: 'Untitled Task'
- Added test data file with tasks without labels
- Added test cases

Closes #47749

Release Notes:

- Fixed: VSCode tasks.json files with tasks missing explicit `label`
fields now parse correctly. Labels are auto-generated matching VSCode's
behavior (e.g., "npm: start").

When two Zed instances share the same data directory (e.g. a release
build and a dev build running simultaneously), SQLite operations can
fail with "database is locked" (error code 5), surfacing as a "Failed to
Launch" error in the agent panel.

The root cause is `PRAGMA busy_timeout=1` in `crates/db/src/db.rs`,
which gives SQLite only 1ms to wait for a write lock before giving up.
With WAL mode, the actual lock hold times are microseconds — the problem
isn't long-held locks, it's that we give up before even trying to wait.
During startup, both instances hit the DB heavily for workspace
restoration, so even tiny overlaps fail.

This changes `busy_timeout` from 1ms to 500ms, giving SQLite more room
to retry without (hopefully) any perceptible delay to the user.

When users have the `multi-workspace` feature flag enabled (agent-v2),
the default dock position for the agent panel is changed from right to
left.

This adds a `update_default_settings` method to `SettingsStore` that
allows mutating defaults in place, then observes the
`AgentV2FeatureFlag` to update the agent dock default accordingly.
Because this modifies the defaults layer, user-configured dock positions
still take precedence.

## Fix incorrect context size limits for GitHub Copilot Chat models

Fixes #44909

### Problem

The agent panel was displaying incorrect token limits for GitHub Copilot
models. Users reported that:
- The agent panel always showed a **128K token limit** for all GitHub
Copilot models, regardless of their actual context window size
- Claude models (e.g., Claude 3.7 Sonnet, Claude Opus 4.5) were showing
~90K instead of their actual 200K context window
- GPT-4o was showing 110K instead of its actual 128K context window
- Users could continue using models beyond the displayed limit, which
worked but was confusing

### Root Cause

The `max_token_count()` method in `copilot_chat.rs` was returning
`max_prompt_tokens` instead of `max_context_window_tokens`:

```rust
// Before (incorrect)
pub fn max_token_count(&self) -> u64 {
    self.capabilities.limits.max_prompt_tokens
}
```

GitHub's API returns three different token-related fields:
- `max_context_window_tokens`: The **full context window size** (e.g.,
200K for Claude 3.7)
- `max_prompt_tokens`: GitHub's limit for prompt input (e.g., 90K for
Claude 3.7)
- `max_output_tokens`: Maximum output tokens (e.g., 16K)

The `max_token_count()` method in the `LanguageModel` trait is expected
to return the **full context window size** — this is consistent with all
other providers (Anthropic returns 200K for Claude, OpenAI returns 128K
for GPT-4o, etc.).

### Solution

<img width="583" height="132" alt="Screenshot 2026-01-25 at 1 07 53 AM"
src="https://github.com/user-attachments/assets/847e2fdb-635d-44bc-a630-2d4867ba8c32"
/>


Changed `max_token_count()` to return `max_context_window_tokens`:

```rust
// After (correct)
pub fn max_token_count(&self) -> u64 {
    self.capabilities.limits.max_context_window_tokens as u64
}
```

### Impact

| Model | Before | After |
|-------|--------|-------|
| Claude 3.7 Sonnet | 90,000 | **200,000** |
| Claude Opus 4.5 | 90,000 | **200,000** |
| GPT-4o | 110,000 | **128,000** |

### Testing

Added a new test
`test_max_token_count_returns_context_window_not_prompt_tokens` that:

1. Deserializes model JSON with distinct `max_context_window_tokens` and
`max_prompt_tokens` values
2. Verifies Claude 3.7 Sonnet returns 200,000 (context window), not
90,000 (prompt tokens)
3. Verifies GPT-4o returns 128,000 (context window), not 110,000 (prompt
tokens)

All existing tests continue to pass:
```
running 4 tests
test tests::test_unknown_vendor_resilience ... ok
test tests::test_max_token_count_returns_context_window_not_prompt_tokens ... ok
test tests::test_resilient_model_schema_deserialize ... ok

  ## Summary

- Fix "Property `ty` is not allowed" warning in `settings.json` for LSP
adapters registered via `register_available_lsp_adapter()`
- Add `available_lsp_adapter_names()` method to include these adapters
in schema generation
- Support `initialization_options` schema lookup for available adapters

  ## Problem

LSP adapters registered via `register_available_lsp_adapter()` were not
included in the settings JSON schema. This caused validation warnings
like:

  Property ty is not allowed

Even though `ty` is a built-in Python language server that works
correctly.

  **Affected adapters:**
  - `ty`, `py`, `python-lsp-server`
  - `eslint`, `vtsls`, `typescript-language-server`
  - `tailwindcss-language-server`, `tailwindcss-intellisense-css`

  ## Solution

  Schema generation now queries both:
  1. `all_lsp_adapters()` - adapters bound to specific languages
2. `available_lsp_adapter_names()` - adapters enabled via settings (new)

  Related: #43104, #45928 
  
  Release Notes:

- Fixed an issue where not all LSP adapters would be suggested for
completion, or recognized as valid in `settings.json`

Release Notes:

- Fixed an issue where a request could fail if an MCP server with names
containing whitespace was used

## Summary

When multiple MCP servers expose tools with the same name, Zed
disambiguates them by prefixing the tool name with the server ID from
settings.json. If the server ID contains spaces or special characters
(e.g., `"Azure DevOps"`), the resulting tool name like `Azure
DevOps_echo` violates Anthropic's API pattern `^[a-zA-Z0-9_-]{1,128}$`,
causing API errors:

> "Received an error from the Anthropic API: tools.0.custom.name: String
should match pattern '^[a-zA-Z0-9_-]{1,128}$'"

## Solution

Convert server IDs to snake_case (using the `heck` crate already
available in the workspace) before using them as prefixes during tool
name disambiguation.

| Server ID in settings.json | Disambiguated Tool Name |
|---------------------------|------------------------|
| `"Azure DevOps"` | `azure_dev_ops_echo` |
| `"My MCP Server"` | `my_mcp_server_echo` |

## Test plan

- [x] Added test case for server name with spaces ("Azure DevOps") in
`test_mcp_tool_truncation`

Closes #37525

By default, thread summary uses default_fast_model (if set), otherwise
default_model, which resolves to openrouter/auto for openrouter
provider. This may cause the summary to be generated by a different
model than the one used by the agent, potentially leading — in cases
such as Claude Opus 4.5 — to summary costs exceeding main agent
execution costs.
The current logic in registry.rs prioritizes default_fast_model over
default_model, which overrides the user-selected model (assigned only to
default_model). Setting default_fast_model = None for the OpenRouter
provider preserves the fallback to openrouter/auto when no model is
chosen, while respecting the user's explicit model selection when one is
provided.

```rust
    pub fn set_default_model(&mut self, model: Option<ConfiguredModel>, cx: &mut Context<Self>) {
        match (self.default_model.as_ref(), model.as_ref()) {
            (Some(old), Some(new)) if old.is_same_as(new) => {}
            (None, None) => {}
            _ => cx.emit(Event::DefaultModelChanged),
        }
        self.default_fast_model = maybe!({
            let provider = &model.as_ref()?.provider;
            let fast_model = provider.default_fast_model(cx)?;
            Some(ConfiguredModel {
                provider: provider.clone(),
                model: fast_model,
            })
        }); // This sets default fast model (in our case openrouter/auto)
        self.default_model = model;  //This sets default_model to user selected model
    }
```

And latter on :
```rust
    pub fn thread_summary_model(&self) -> Option<ConfiguredModel> {
        #[cfg(debug_assertions)]
        if std::env::var("ZED_SIMULATE_NO_LLM_PROVIDER").is_ok() {
            return None;
        }

        self.thread_summary_model
            .clone()
            .or_else(|| self.default_fast_model.clone()) // We pick fast_model over default model here
            .or_else(|| self.default_model.clone())
    }
```
Which results in user choice being ignored.

Proposed behavior:

Use the model explicitly selected by the user in Zed agent
configuration.
If no model is specified, fall back to the configured default.

The resolution is to set in :  provider/open_router.rs
```rust
fn default_fast_model(&self, _cx: &App) -> Option<Arc<dyn LanguageModel>> {
     None
}
```
This will have a consequence of default_fast_model not being provided
and falling back to user choice - but once the fast model is set via for
example a configuration property - the default_fast_model is picked over
default_model

Release Notes:

- open_router: Use user's default model when comments and thread summary

Closes #47404

Release Notes:

- Fixed MCP tool results not displaying after restarting Zed

Previously, when an MCP server returned a tool response with
`is_error: true`, the error content was incorrectly treated as

the tool call succeeded when it actually failed.

Now we check the `is_error` flag and propagate the error message
properly, allowing the agent to handle failures appropriately.

This PR adds ability to select and test audio input/output devices for
use in collaboration setting (which is what the team at Zed relies
heavily on). Currently, we only ever used whatever the system default is
and it worked well until it didn't - for some reason, when I am on my
Linux laptop, I am unable to force Zed to use my external mic +
headphones via external USB audio interface. With this PR, now I can
list all available devices and select the one I want.

There are still a couple of caveats that we should be aware of:
* I've decided to list *all* available devices meaning on Linux it is
quite possible that you may discover that what your desktop environment
is reporting to you is a significantly shorter list than what your sound
framework/hw is actually exposing. I think this makes sense given my
inexperience with audio drivers/devices and frameworks on various OSes
so that we get full control over what is available with the goal of
being able to come up with some filtering heuristic as we go along.
* We currently populate the list of available audio devices only once at
startup meaning if you unplug your device while you have Zed running
this will not register until you restart Zed which is a PITA. However,
in order to keep the changes manageable I thought it would be best to do
minimal work in this regard now, and iterate on this some more in the
near future. After all, we don't really monitor device changes on any
platform except macOS anyhow, so it might be the case that when I get
round to implementing this I will have the opportunity to tackle both at
the same time.
* In order to get a valid list of all audio devices using `cpal` crate
(which is the building block of `rodio`), I had to bump `cpal` to 0.17,
and pin `rodio` to a more recent commit sha as a result, so if you see
any regressions, lemme know and/or feel free to revert this PR.
* Finally, I've done my best to integrate this with the settings UI, but
I am sure more could be done in terms of styling, etc.

Closes #47527
## Summary
The include/exclude filters in Project Search now support standard glob
brace syntax like `{a,b}`.
**Before:** `crates/{search,project}/**/file.rs` would error with
"unclosed alternate group"
**After:** Pattern correctly matches files in both `crates/search/` and
`crates/project/`
## Implementation
Added `split_glob_patterns()` function that splits by comma only when
not inside braces, preserving the `{a,b}` syntax that `globset` natively
supports.

Release Notes:

- Added support for `{a,b}` glob syntax in project search
include/exclude filters

Follow-up to https://github.com/zed-industries/zed/pull/46641.

In the PR linked above, I had introduced a dropdown that'd show up in
the title bar when the workspace contained more than one project.
Although that helped improve the multi-project use case, it created some
quirky designs:

- The project dropdown and the recent project pickers looked too
different from one another
- The transition between the 2 project case to the 1 project scenario,
from the dropdown, was not great, because you'd be then seeing the
bigger recent projects picker
- The `workspace: switch project` action was still reachable in the
command palette even if you had one project in the workspace

So, what this PR does is essentially fixing all of this by consolidating
it all in the Recent Projects picker. If you are in a multi-project
scenario, the picker will display a section with all of the projects on
the workspace allowing you to activate each one of them. The picker also
looks simpler when you reach it by clicking on the project name in the
title bar, as opposed to through the keybinding. I've then removed the
project dropdown code as well as the action, given we don't need them
anymore due to the consolidation. Lastly, I tackled the inconsistent
wording used between "Folders", "Projects", and "Workspaces".

Here's the result:

Release Notes:

- Workspace: Improved the recent projects picker by making it also
display active projects in case of a multi-project workspace.

This patch updates the description of the `edit_file` tool to recommend
models to use the `move_path` tool instead of the `terminal` tool to
move or rename files. The `move_path` tool is more specific and shall be
preferred as it provides a better UI and dedicated permissions.

Release Notes:

- N/A

Add workspace::CloseItemInAllPanes action that closes the active
item's buffer in every pane where it's open, matching Vim's `:bdelete`
semantics. Pane layout is preserved, only the buffer is removed.

`:bd` respects pinned tabs, `:bd!` overrides them and skips save.

Also refactors the tab switcher's close button to use the new
`close_items_with_project_path` method, removing duplicated logic.

Release Notes:

- Vim: `:bd` (`:bdelete`) now closes the file in all panes where it's
open
- Added `workspace::CloseItemInAllPanes` action to close a file across
all panes

## Summary

Creating a new file via the file picker incorrectly used the focused
file's directory as the target even when that file did not belong to any
open worktree (e.g., Zed opened to a single file, settings.json focused
without a worktree, or an external file focused). This PR changes the
selection logic so the picker only uses the focused file's worktree if
that file actually belongs to one of the visible project worktrees;
otherwise, it falls back to the existing project heuristic (query-root
match or project default), which prevents misdirected file creation.
This addresses
[zed-industries/zed#41940](https://github.com/zed-industries/zed/issues/41940).

---

## Problem

### Scenarios that errored or created in the wrong place:

1. **Zed opened to a single file from the CLI** (no worktree)
- Create New was offered and then failed or targeted a non-project
directory

2. **No worktree open with settings.json focused**
   - Same failure mode as above

3. **A worktree is open but settings.json is focused**
   - Create New used settings.json's directory

4. **A worktree is open but an external (non-worktree) file is focused**
   - Create New used the external file's directory

### Root Cause

`set_search_matches` unconditionally overwrote `expect_worktree` using
the `currently_opened_path` worktree_id, even if the focused file was
not part of any visible worktree.

---

## Fix

### Query-derived worktree remains primary:

- Try to match the query path against the roots of visible worktrees
- If it matches, use that worktree and strip the root prefix from the
query to get the relative path

### Only use the focused file as a secondary signal if it is relevant:

- Check whether the focused file's `worktree_id` exists within visible
worktrees
- Only then override `expect_worktree`

If no worktree is determined (e.g., no worktrees are open), Create New
is not offered.

---

## Implementation Details

- **Iterate over `&available_worktree`** when scanning roots and clone
the matched entity to avoid moving out of the iterator

- **Validate focused file worktree membership:**
- Compute `focused_file_in_available_worktree` by scanning visible
worktrees for a matching id
  - Override `expect_worktree` only if that check passes

- **Preserve existing guard rails for Create New:**
- Only push `Match::CreateNew` when a concrete `expect_worktree` is
present and the query doesn't end with a trailing separator

---

## Key Code Changes

### Before

Always overwrote `expect_worktree` with the focused file's
`worktree_id`, even for external or non-project files.

### After

Only override `expect_worktree` when the focused file belongs to a
visible worktree. Otherwise, keep the query-derived or default project
worktree.

---

## User-Facing Behavior

### No Worktree Open

*Example: Zed launched with a single file or only settings.json visible*

- The file picker will **not** offer "Create New"

### Worktree Open + Non-Project File Focused

*Example: A non-project file or settings.json is in focus*

- "Create New" is offered
- New file is created within the project worktree (based on root match
or project default)
- New file is **never** created beside the external file

### Multiple Worktrees Open + Query Rooted to One

*Example: Query specifies a particular worktree root*

- The worktree is selected by root-name match
- Project default selection applies if no match is found

---

## Tests

### Added:
`test_create_file_focused_file_not_belong_to_available_worktrees`

1. Set up two worktrees A and B; open an external file that belongs to
neither
2. Use the file picker to create "new-file.txt"
3. Assert the new file opens in an editor whose
`ProjectPath.worktree_id` equals either A or B, and the relative path is
"new-file.txt"

Existing tests for Create New, absolute/relative matching, and
multi-worktree behavior continue to pass.

---

## Reproduction Steps (Pre-Fix)

1. Launch Zed with a single file:
   ```bash
   zed /tmp/foo.txt
   ```
   Or open settings.json with no project

2. Open the file finder and type a new filename, then press Enter

3. Observe Create New trying to use the focused file's directory or
failing unexpectedly

---

## Expected vs Actual

### Expected:

- No Create New when there is no project worktree
- When a project exists, Create New targets the appropriate worktree,
not the focused external file's directory

### Actual (pre-fix):

- Create New used the focused file's directory, even if it was external
or unrelated to the project

---

## Migration and Compatibility

- No user configuration changes required
- Behavior now aligns with user expectation: Create New is only offered
when a project worktree is available and it always targets a project
worktree

---

## Reference

**Fixes:**
[zed-industries/zed#41940](https://github.com/zed-industries/zed/issues/41940)
Fixes #41940 

---

## Appendix: Code Snippets

### Guard before overriding with focused file:

```rust
let focused_file_in_available_worktree = available_worktree.iter().any(|wt| wt.read(cx).id() == worktree_id);

if focused_file_in_available_worktree { 
    expect_worktree = project.worktree_for_id(worktree_id, cx); 
}
```

### Root-based worktree selection with non-moving iteration:

```rust
for worktree in &available_worktree { 
    if query_path.strip_prefix(worktree.read(cx).root_name()).is_ok() { 
        expect_worktree = Some(worktree.clone()); 
        …
    } 
}
```

---

This PR includes a targeted test ensuring that when the focused file is
outside all worktrees, Create New still creates within the project
worktree(s), preventing regressions.

---
## Release Notes

- Fixed "Create New" in the file picker targeting the wrong directory
when a non-project file was focused.

This makes the `zed --add <PATH>` command use the window it was run from
when run from a Terminal Panel. I run into this paper cut quite a lot
working with multiple projects and preferring to create new files
through the CLI instead of the GUI.


**Before**
With two windows open, running `zed --add a.txt` in one window's
terminal might open the file `a.txt` in the other window.
