This PR moves the UI-dependent logic in the `agent` crate into its own
crate, `agent_ui`. The remaining `agent` crate no longer depends on
`editor`, `picker`, `ui`, `workspace`, etc.
This has compile time benefits, but the main motivation is to isolate
our core agentic logic, so that we can make agents more
pluggable/configurable.
Release Notes:
- N/A
CC: @danilo-leal Do you have thoughts on this? I found myself typing
chat messages after a long thread and then deciding I would be better
served by restarting from a summary -- and then "poof" the contents of
my chat box was lost.
Release Notes:
- agent: "New From Summary" now preserves any unsent content in the chat
box.
Previously, if editing a long previous user message in the thread, you'd
have a double scroll situation because the editor used in that case had
its max number of lines capped. To solve that, I made the `max_lines` in
the editor `AutoHeight` mode optional, allowing me to not pass any
arbitrary number to the previous user message editor, and ultimately,
solving the double scroll problem by not having any scroll at all.
Release Notes:
- agent: Fixed double scroll that happened when editing a long previous
user message.
@ConradIrwin adding you as a reviewer as I'm touching editor code
here... want to be careful. :)
Having `Thread::last_usage` as an override of the initially fetched
usage could cause the initial usage to be displayed when the current
thread is empty or in text threads. Fix is to just store last usage info
in `UserStore` and not have these overrides
Release Notes:
- Agent: Fixed request usage display to always include the most recently
known usage - there were some cases where it would show the initially
requested usage.
Follow up to https://github.com/zed-industries/zed/pull/32765.
This PR creates a slot for the `message_editor::create_editor` to allow
using different values for min and max lines. In practice, the panel's
main editor now has a minimum of 4 lines, whereas the previous message
editor has just one. This makes the layout shift when clicking on a
previous message to edit it much smaller.
Release Notes:
- agent: Improved layout shift when clicking to edit a previous sent
message.
Previously we were using a mix of `u32` and `usize`, e.g. `max_tokens:
usize, max_output_tokens: Option<u32>` in the same `struct`.
Although [tiktoken](https://github.com/openai/tiktoken) uses `usize`,
token counts should be consistent across targets (e.g. the same model
doesn't suddenly get a smaller context window if you're compiling for
wasm32), and these token counts could end up getting serialized using a
binary protocol, so `usize` is not the right choice for token counts.
I chose to standardize on `u64` over `u32` because we don't store many
of them (so the extra size should be insignificant) and future models
may exceed `u32::MAX` tokens.
Release Notes:
- N/A
This is a follow up to my original attempt
https://github.com/zed-industries/zed/pull/30878 and to the PR that
eventually reverted parts of it because it broke stuff
https://github.com/zed-industries/zed/pull/31295. This new approach
attaches the `scroll_to_bottom` feature to the `chat` function, which is
triggered when the `Chat` action is dispatched by the "send" icon
buttons. With that, and from my testing, the thread doesn't forcefully
scroll as new messages are added, which was the regression I had
introduced.
Release Notes:
- agent: The panel nows scrolls to the bottom after submitting a new
message, allowing to see it more easily.
Previously, you could only accept and reject all changes from a specific
file by checking that file out on a tab. Now, you can do that via the
message editor changes summary bar. The buttons appear as you hover over
the file item in the accordion.
Here's what it looks like:
<img
src="https://github.com/user-attachments/assets/8c0843d3-9bf1-4588-8b42-4cd8d0798a68"
width="500" />
Release Notes:
- agent: Enable accepting and rejecting individual file changes from
message editor.
* Adds `min_lines` to `EditorMode::AutoHeight` and use `min_lines: 4` in
agent message editor. This makes it so that clicks in the blank space
below the first line of the editor also focus it, instead of needing to
click the very first line.
* Removes the div wrapping the editor, as it was only there to set
`min_h_16()`. This also tightens up the min space given to the editor -
before it was not evenly dividing the number of lines.
* Further tightens up vertical spacing by using `gap_1` instead of
`gap_4` between editor and controls below
At 4 line min height (after on the left, before on the right):
At 5 lines, one more than min height (after on the left, before on the
right):
Release Notes:
- Agent: Fixed clicking to focus the message editor to also work for
clicks below the last line.
Previously, upon getting close to reaching the context window, we'd just
suggest creating a new thread using the summary of the current one. Now,
we also suggest turning burn mode on as an alternative action to solve
the context window problem.
Release Notes:
- agent: Added a suggestion to turn burn mode on when getting close to
the context window limit.
What motivated me to refactor this component was the fact that I wanted
a new variant to allow having _two CTAs_ instead of just one. This
variant should work with either a single or multiline description. But,
given we were using a `Callout::single_line` and `Callout::multi_line`
API, I'd then need to have both `Callout::single_line_one_button` and
`Callout::single_line_two_buttons` type of variants, which just points
to a combinatorial problem.
With this refactor, the Callout now follows the same structure of the
Banner component, where it's all `Callout::new` and every method is
passed as if they were props in a React component, allowing for a more
flexible design where you can customize button styles. Also made it
slightly more robust for wrapping and removed the top border as that
should be defined by the place it is being used in.
Release Notes:
- N/A
I think we mistakenly added an early return for the review multibuffer
button if `has_pending_edit_tool_uses` is true. It is totally fine _to
access_ the review multibuffer while that's happening. It's another
thing to _accept and reject_ changes while they're still ongoing!
Release Notes:
- agent: Fixed access to the review multibuffer from the agent panel.

While working on something else I found this weird behaviour in message
editor of agent panel. When model names are too long, the model selector
would expand and push the send button outside the visible area. This
change fixes the flex layout to ensure the send button always remains
accessible while properly truncating long model names.
Closes #ISSUE
Release Notes:
- Fix agent panel model selector layout pushing send button off screen

This allows storing the profile per thread, as well as moving the logic
of which tools are enabled or not to the profile itself.
This makes it much easier to switch between profiles, means there is
less global state being changed on every profile change.

Noticed while working on #31848 that we do not support pasting images as
context in the inline assistant
Release Notes:
- agent: Add support for attaching images as context from clipboard in
the inline assistant
Closes#31781
Currently we don't any warning or error if the image is not supported by
the current model in selected in the agent panel which leads for users
to think it's supported as there is no visual feedback provided by zed.
This PR adds a warning on image context pill to show warning when the
model doesn't support it.

This PR is a refactor of the existing `ModelType` in
`agent_model_selector`.
In #31848 we also need to know which context we are operating in, to
check if the configured model has image support.
In order to deduplicate the logic needed, I introduced a new type called
`ModelUsageContext` which can be used throughout the agent crate
Release Notes:
- N/A
This PR introduces the "Reject All" and "Accept All" buttons in the
panel's edit bar, which appears as soon as the agent starts editing a
file. I'm also adding here a new method to the thread called
`has_pending_edit_tool_uses`, which is a more specific way of knowing,
in comparison to the `is_generating` method, whether or not the
reject/accept all actions can be triggered.
Previously, without this new method, you'd be waiting for the whole
generation to end (e.g., the agent would be generating markdown with
things like change summary) to be able to click those buttons, when the
edit was already there, ready for you. It always felt like waiting for
the whole thing was unnecessary when you really wanted to just wait for
the _edits_ to be done, as so to avoid any potential conflicting state.

Follow up to https://github.com/zed-industries/zed/pull/31470.
I started looking at config and changed preferred_completion_mode to
burn to only find its max so made changes to align it better with
rebrand. As this is in preview build now.
This doesn't touch zed_llm_client. Only the Zed changes the code and doc
to match the new UI of burn mode. There are still more things to be
renamed, though.

One caveat with this PR is that the keybinding still doesn't work for text threads. Will do that in a follow-up.
Release Notes:
- agent: Added a keybinding to toggle Burn Mode on and off.
This PR improves the consecutive tool call UX by allowing users to
quickly continue an interrupted with one-click. What we do here is
insert a hidden "Continue" message that will just nudge the LLM to keep
going. We're also using the opportunity to upsell the previously called
"Max Mode", now rebranded as "Burn Mode", which allows users to don't be
interrupted anymore if they ever have 25 consecutive tool calls again.

- agent: Improve consecutive tool call UX by allowing users to quickly

Editing JSON styles is not very helpful for bringing style changes back
to the actual code. This PR adds a buffer that pretends to be Rust,
applying any style attribute identifiers it finds. Also supports
completions with display of documentation. The effect of the currently
selected completion is previewed. Warning diagnostics appear on any
unrecognized identifier.

Adds a `#[derive_inspector_reflection]` macro which allows these methods
to be enumerated and called by their name. The macro code changes were
95% generated by Zed Agent + Opus 4.
Release Notes:
* Added an element inspector for development. On debug builds,
`dev::ToggleInspector` will open a pane allowing inspecting of element
info and modifying styles.
Addresses an issue where the agent context token meter in the panel
toolbar (showing usage like "X / Y tokens") failed to update its count
after the user cleared the current context via the context editor UI.
While the meter updated correctly when adding items, clearing them left
the display showing the old count.
The root cause was traced to the `ContextStore::clear` method in
`crates/agent/src/context_store.rs`. This method correctly cleared the
internal data structures holding the context items but neglected to call
`cx.notify()` to inform listeners of the state change. Consequently, the
UI components responsible for displaying the token count were not
triggered to re-render with the new (presumably lower) count.
This PR fixes the issue by adding the missing `cx.notify()` call to the
`ContextStore::clear` method. This ensures listeners are notified when
the context set is cleared, allowing the token meter UI to update
correctly.
Release Notes:
- Fixed an issue where the agent context token meter did not update when
the context was cleared.
This PR introduces a new `agent: chat with follow` action that
automatically enables "Follow Agent" when submitting a chat message with
`cmd-enter` or `ctrl-enter`. This is experimental. I'm not super
thrilled with the name, but the root action to submit a chat is called
`agent: chat`, so I'm following that wording. I'm also unsure if the
binding feels right or not.
Release Notes:
- Added an `agent: chat with follow` action via `cmd-enter` on macOS and
`ctrl-enter` on Linux
Open inspector with `dev: toggle inspector` from command palette or
`cmd-alt-i` on mac or `ctrl-alt-i` on linux.

Reverts back to previous behavior where we update your settings so we
can load a new thread from your last configuration.
Release Notes:
- agent: Persist profile changes for new threads
When deciding if a model supports tools or not, we weren't reading from
the configured model in a given thread.
This also stores the profile on the thread, which matches the behavior
of the Model and Max Mode, which we also already store per thread.
Hopefully this helps alleviate some confusion.
Release Notes:
- agent: Save profile selection per-Agent thread

This PR fixes the profile menu flickering due to the documentation aside
after updating the agent dock position over the settings file.
The problem arose because the `documentation_side` could get out of sync
with the actual agent panel dock position. The `documentation_side` was
only updated whenever the user changed the agent panel position using
the UI, but not when updating the position in the settings file.
You can reproduce this easily by changing the `agent.dock` position to
the opposite site in your settings, which will make the profile menu
flicker again in some scenarios due to the de-sync.
This PR fixes this behavior by computing the position during render,
thus the actual set panel position and the documentation position can
never get out of sync
Release Notes:
- Fixed the agent profile menu flickering after updating the assistant
panel dock position in the settings.
Release Notes:
- Fixed a bug that would cause the message composer in the agent panel
to not render when the context strip was empty.

You can set `agent_font_size` as a top-level settings key. You can also
use `zed::IncreaseBufferFontSize` and `zed::DecreaseBufferFontSize` and
`zed::ResetBufferFontSize` the agent panel is focused via the standard

sense to rename these actions to be more general since "buffer" is now a
