Addresses a regression introduced by
https://github.com/zed-industries/zed/pull/44021 that caused @mentions
and slash commands to stop working if you set
`show_completions_on_input: false` in your settings.
In this case, we should always show these menus, otherwise the features
won't work at all.
Release Notes:
- N/A
Uses the latest version of the SDK + schema crate. A bit painful because
we needed to move to `#[non_exhaustive]` on all of these structs/enums,
but will be much easier going forward.
Also, since we depend on unstable features, I am pinning the version so
we don't accidentally introduce compilation errors from other update
cycles.
Release Notes:
- N/A
Gist is we only need to block the foreground thread for reparsing if
immediate language changes are useful to the user. That is usually only
the case when they edit the buffer
Release Notes:
- Improved performance of large project searches and project diffs

Summary
Fixed the thread deletion issue by:
1. Click handler conflict between the trash icon and the main ListItem
2. Added `cx.stop_propagation()` to prevent the click event from
bubbling up to the parent ListItem's click handler
3. Followed the established `cx.stop_propagation()` pattern used
throughout the codebase
Now when you click the trash icon to delete a thread:
- ✅ The thread deletion happens immediately on the first click
- ✅ No race condition between deletion and activation
- ✅ No double-clicking required
The fix is minimal, follows established patterns, and addresses the
exact root cause of the issue.
- Stop event propagation in thread removal handler
Release Notes:
- agent: Improved delete thread action in the history view by preventing
it from also triggering the thread activation.
Closes https://github.com/zed-industries/zed/issues/43721
This PR makes the loading state clearer by disabling the message editor
while the agent is loading as well as pulsating the icon.
Release Notes:
- agent: Made the thread loading state clearer in the agent panel.
Closes https://github.com/zed-industries/zed/issues/43728
Release Notes:
- agent: Fixed a bug where the plan and edit files list would consume
the whole space of the thread if they were too long. They're now capped
by a max-height and scrollable.
Sometimes we are unable to receive messages at all from an agent. This
puts on upper bound on the `initialize` call so we can at least give a
message to the user that something is wrong here.
30s might feel like too long, but I wanted to avoid some false positives
in case there was something an agent needed to do at startup. This will
still communicate to the user at some point that something is wrong,
rather than leave them waiting forever with no signal that something is
going wrong.
Release Notes:
- agent: Show an error message to the user if we are unable to
initialize an ACP agent in a reasonable amount of time.
We were using `std::path::Path::strip_prefix` to determine which
repository an absolute path belongs to, which doesn't work when the
paths are Windows-style but the code is running on unix. Replace it with
a platform-agnostic implementation of `strip_prefix`.
Release Notes:
- Fixed git features not working when a Windows host collaborates with a
unix guest
It is easy for us to get the two fields out of sync causing weird
problems, there is no reason to have both here so.

Consider the following flow: you submit prompt A. Prompt A generates
some edits. You don't click on either "reject" or "keep"; they stay in a
pending state. You then submit prompt B, but before the agent outputs
any response, you click to edit prompt B, thus submitting a
regeneration.
Before this PR, the above flow would make the edits originated from
prompt A to be auto-rejected. This feels very incorrect and can surprise
users when they see that the edits that were pending got rejected. It
feels more correct to only auto-reject changes if you're regenerating
the prompt that directly generated those edits in the first place. Then,
it also feels more correct to assume that if there was a follow-up
prompt after some edits were made, those edits were passively
"accepted".
So, this is what this PR is doing. Consider the following flow to get a
picture of the behavior change:
- You submit prompt A.
- Prompt A generates some edits.
- You don't click on either "reject" or "keep"; they're pending.
- You then submit prompt B, but before the agents outputs anything, you
click to edit prompt B, submitting a regeneration.
- Now, edits from prompt A will be auto-kept.
Release Notes:
- agent: Improved the "reject"/"keep" behavior when regenerating older
prompts by auto-keeping pending edits that don't originate from the
prompt to-be-regenerated.
This PR makes the thread markdown editable. This refers to the "open
thread as markdown" feature, where you previously could only read. One
benefit of this move is that it makes a bit more obvious that you can
`cmd-s` to save the markdown, allowing you to store the content of a
given thread. You could already do this before, but due to it being
editable now, you see the tab with a dirty indicator, which communicates
that better.
Release Notes:
- agent: Made the thread markdown editable.
Fixes a panic that was introduced in #42633. Repro steps:
1. Open the inline assistant and mention a file in the prompt
2. Run the inline assistant
3. Remove the mention and insert a different one
4. 💥
This would happen because the mention set still had a reference to the
old editor, because we create a new one in `PromptEditor::unlink`.
Also removes the unused
`crates/agent_ui/src/context_picker/completion_provider.rs` file, which
was not removed by mistake in the previous PR.
Release Notes:
- N/A
This PR adds back the footer with the "Configure" button in the model
selector but only when the seeing it from the Zed agent (or inline
assistant/text threads). I had removed it a while back because seeing
the "Configure" button, which takes you to the agent panel settings
view, when clicking from an external agent didn't make much sense, given
there's nothing model-wise you can configure from Zed (at least yet) for
an external agent.
This also makes the button in the footer a bit nicer by making it full
screen and displaying a keybinding, so that you can easily do the whole
"trigger model selector → go to settings view" all with the keyboard.

Release Notes:
- N/A
This PR builds on top of the `default_mode` feature where it was
possible to set an external agent mode as the default if you held a
modifier while clicking on the desired option. Now, if you want to have,
for example, Haiku as your default Claude Code model, you can do that.
This feature adds parity between external agents and Zed's built-in one,
which already supported this feature for a little while.
Note: This still doesn't work with external agents installed from
extensions. At the moment, this is limited to Claude Code, Codex, and
Gemini—the ones we include out of the box.
Release Notes:
- agent: Added the ability to set a model as the default for a given
built-in external agent (Claude Code, Codex CLI, or Gemini CLI).
This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.
This PR also uncovered two minor bugs due to that.
Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

- N/A *or* Added/Fixed/Improved ...
Closes https://github.com/zed-industries/zed/issues/32701
Release Notes:
- agent: Fixed a bug where hitting the `NewThread` keybinding when
focused inside a terminal within the agent panel would create a new
terminal tab instead of a new thread.
This PR makes the description in the callout that display general errors
in the agent panel be rendered as markdown. This allow us to pass URLs
to these error strings that will be clickable, improving the overall
interaction with them. Here's an example:

/>
Release Notes:
- agent: Improved the interaction with errors by allowing links to be
clickable.
Closes https://github.com/zed-industries/zed/issues/36330
Closes https://github.com/zed-industries/zed/issues/35460
This PR improves how we display markdown tables by relying on grids
rather than flexbox. Given this makes text inside each cell wrap, I
ended up removing the `table_overflow_x_scroll` method, as it was 1)
used only in the agent panel, and 2) arguably not the best approach as a
whole, because as soon as you need to scroll a table, you probably need
more elements to make it be really great.
One thing I'm slightly unsatisfied with, though, is the border
situation. I added a half pixel border to the cell so they all sum up to
1px, but there are cases where there's a tiny space between rows and I
don't quite know where that's coming from and how it happens. But I
think it's a reasonable improvement overall.

Release Notes:
- agent: Improved table rendering in the agent panel, ensuring cell text
wraps, not going off-screen.
Closes https://github.com/zed-industries/zed/issues/37087
This PR adds an icon button to the footer of the message editor enabling
to trigger and interact with the @-mention completions menu with the
mouse. This is a first step towards making other types of context you
can add in Zed's agent panel more discoverable. Next, I want to improve
the discoverability of images and selections, given that you wouldn't
necessarily know they work in Zed without a clear way to see them. But I
think that for now, this is enough to close the issue above, which had
lots of productive comments and discussion!

src="https://github.com/user-attachments/assets/fd028442-6f77-4153-bea1-c0b815da4ac6"
/>
Release Notes:
- agent: Added an icon button in the agent panel that allows to trigger
the @-mention menu (for adding context) now also with the mouse.
This PR creates a dedicated function for the agent panel message
editor's placeholder text so that we can wait for the agent
initialization to capture whether they support slash commands or not. On
the one (nice) hand, this allow us to stop matching agents by name and
make this a bit more generic. On the other (bad) hand, the "/ for
commands" bit should take a little second to show up because we can only
know whether an agent supports it after it is initialized.
This is particularly relevant now that we have agents coming from
extensions and for them, we would obviously not be able to match by
name.
Release Notes:
- agent: Fixed agent panel message editor's placeholder text by making
it more accurate as to whether agents support slash commands,
particularly those coming from extensions.
Closes https://github.com/zed-industries/zed/issues/42356
This PR fixes the history view losing focus by simply always displaying
the search editor. I don't think it's too weird to not have it when it's
empty, and it also ends up matching how regular pickers work.
Release Notes:
- agent: Fixed a bug where navigating the agent panel with the keyboard
wouldn't work if you visited the history view and it was empty/had no
entries.
Closes#42178
Now it's consistent with the DateAndTime path which already does
timezone conversion.
- **Future Work**
Happy to tackle the TODO in `time_format.rs` about implementing native
Windows APIs for proper localized formatting (similar to macOS's
`CFDateFormatter`) as a follow-up.
Release Notes:
- agent: Fixed the thread history item timestamp, which was being shown
in GMT instead of in the user's local timezone on Windows.
We can always include symbols, since we either include a ResourceLink to
the symbol (when `PromptCapabilities::embedded_context = false`) or a
Resource (when `PromptCapabilities::embedded_context = true`)
Release Notes:
- Fixed an issue where symbols could not be included when using specific
ACP agents
Agents running in extensions need to have a root directory of the
extension's dir for installation and authentication, but *not* for the
conversation itself - otherwise the agent is running things like
terminal commands in the wrong dir.
Release Notes:
- Fixed Agent Server extensions having the current working directory of
the extension rather than the project
