Drop the `count_tokens` API and related implementations across
providers, and remove the unused `tiktoken-rs` dependency.
I was going to update the dependency becuase they finally released a fix
we needed. But then I realized we only used this api in one place, the
Rules library. And for most models it would have been wildly incorrect
becuase we use tiktoken, i.e. OpenAI tokenizers, for almost every model,
which is going to give incorrect results.
Given that, I just removed these because the difference in how we get
these has caused plenty of confusion in the past.

Recently, we changed the behavior of pickers so that hovering matches
would also select them. This makes sense for most pickers that are used
as "regular" pickers, but we have some in Zed that are not. A great
example of one is the rules library, which sort of became way less
usable with this behavior. So, this PR introduces a simple bool trait
method to the picker so that we can turn this behavior off whenever
necessary. The rules library kicks off as the only instance of it being
turned off.
Release Notes:
- Fix navigation within the rules library making it so hovering the
sidebar doesn't activate the visible rule.
This PR changes the API for the `ListItem`'s `end_hover` slot so that
whatever is in there is always part of the flex stack, as opposed to an
absolutely-positioned element. Additionally, I'm also improving the API
for swapping content between the default state and the hovered state
(e.g., list items where by default we render X, but when you hover, we
show something else). Lastly, I'm adding buttons to some Git picker
items that were only previously available through modal footer buttons.

## Context
User keybindings using `action::Sequence` (e.g., mapping Escape in
insert mode
to a sequence of `vim::NormalBefore` + another action) don't work in the
RulesLibrary window. The `ActionSequence` handler is only registered on
the
`Workspace` view, but the RulesLibrary opens as a separate window
without a
Workspace in its element tree, so the action has no handler and fails to
dispatch.
This adds the `ActionSequence` handler to the RulesLibrary root element,
matching the same pattern used in Workspace.
Closes#51721
## How to Review
Small PR — single file change in
`crates/rules_library/src/rules_library.rs`.
Focus on the new `.on_action()` for `ActionSequence` in the `Render`
impl.

Previously, if you wanted to have a button that contains icons on both
edges, you'd need to use a `ButtonLike` component, which takes any
children. Meanwhile, the `Button` would only take one icon, where you
could control its position through the `IconPosition` enum. This has
always felt unnecessarily limiting. So, this PR removes this limitation
by adding two new methods to the button: `start_icon` and `end_icon`.
In the meantime, I have also been bothered by the unnecessary
indirection in the `IconButton` due to the existence of the `ButtonIcon`
component. So I figured I could also completely eliminate that by adding
some of its methods directly to the `IconButton` and in the Button, just
using a regular `Icon` component.
---
## Before
```rust
Button::new("id", "Label")
.icon(IconName::Plus)
.icon_position(IconPosition::Start)
.icon_size(IconSize::Small)
.icon_color(Color::Muted)
```
## After
```rust
Button::new("id", "Label")
.start_icon(Icon::new(IconName::Check))
.end_icon(Icon::new(IconName::ChevronDown).size(IconSize::XSmall))
```
This should have no visual impact to the UI.

This PR fixes an issue on macOS where dragging title bar buttons and
other UI elements would drag the window instead of no-op, like in native
Mac apps. That made interactions like selecting text with the mouse
impossible in those areas, including the title input in Rules Library.
We don't want to handle this at GPUI level, since you might still want
this dragging behavior while having no native titlebar for some apps,
and without implementing your own handler. So, we just handle this for
Zed.
On macOS, we now set `is_movable: false` on all windows, which disables
that drag-anything behavior and relies on the native window drag handler
for window dragging instead.
This also meant implementing a platform title bar for the sidebar in
Rules Library, since dragging there was previously handled by the
`is_movable` behavior. We already had a full-width platform title bar
there on other platforms. On macOS, it is sidebar-only to keep existing
design.
Release Notes:
- N/A
This is a staff only toggle for now, since the consequences of
activating it are not obvious and quite dire (tokens costs 6 times
more).
Also, persist thinking, thinking effort and fast mode in DbThread so the
thinking mode toggle and thinking effort are persisted.
Release Notes:
- Agent: The thinking mode toggle and thinking effort are now persisted
when selecting a thread from history.
Release Notes:
- Added agent panel restoration. Now restarting your editor won't cause
your thread to be forgotten.

The rate limiter's semaphore guard was being held for the entire
duration of a turn, including during tool execution. This caused
deadlocks when subagents tried to acquire permits while parent requests
were waiting for them to complete.
## The Problem
In `run_turn_internal`, the stream (which contains the `RateLimitGuard`
holding the semaphore permit) was kept alive throughout the entire loop
iteration - including during **tool execution**:
1. Parent request acquires permit
2. Parent starts streaming, consumes response
3. Parent starts executing tools (subagents)
4. **Stream/guard still held** while tools execute
5. Subagents try to acquire permits → blocked because parent still holds
permit
6. Deadlock if all permits are held by parents waiting for subagent
children
## The Fix
Two changes were made:
1. **Drop the stream early**: Added an explicit `drop(events)` after the
stream is fully consumed but before tool execution begins. This releases
the rate limit permit so subagents can acquire it.
2. **Removed the `bypass_rate_limit` workaround**: Since the root cause
is now fixed, the bypass mechanism is no longer needed.
Note: no release notes because subagents are still feature-flagged, and
this rate limiting change isn't actually observable without them.
Release Notes:
- N/A
## Problem
When subagents use the `edit_file` tool, it creates an `EditAgent` that
makes its own model request to get the edit instructions. These "nested"
requests compete with the parent subagent conversation requests for rate
limiter permits.
The rate limiter uses a semaphore with a limit of 4 concurrent requests
per model instance. When multiple subagents run in parallel:
1. 3 subagents each hold 1 permit for their ongoing conversation streams
(3 permits used)
2. When all 3 try to use `edit_file` simultaneously, their edit agents
need permits too
3. Only 1 edit agent can get the 4th permit; the other 2 block waiting
4. The blocked edit agents can't complete, so their parent subagent
conversations can't complete
5. The parent conversations hold their permits, so the blocked edit
agents stay blocked
6. **Deadlock**
## Solution
Added a `bypass_rate_limit` field to `LanguageModelRequest`. When set to
`true`, the request skips the rate limiter semaphore entirely. The
`EditAgent` sets this flag because its requests are already "part of" a
rate-limited parent request.
(No release notes because subagents are still feature-flagged.)

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.

Problem:
- The status bar’s pending keystroke indicator (shown next to --NORMAL--
in Vim mode) didn’t clear when focus moved to another context, e.g.
hitting g in the editor then clicking the Git panel. The keymap state
correctly canceled the prefix, but observers that render the indicator
never received a “pending input changed” notification, so the UI kept
showing stale prefixes until a new keystroke occurred.
Fix:
- The change introduces a `pending_input_changed_queued` flag and a new
helper `notify_pending_input_if_needed` which will flushes the queued
notification as soon as we have an App context. The
`pending_input_changed` now resets the flag after notifying subscribers.

Previously, this was controllable via the undocumented
ZED_WINDOW_DECORATIONS environment variable (added in #13866). Using an
environment variable for this is inconvenient because it requires users
to set that environment variable somehow before starting Zed, such as in
the .desktop file or persistently in their shell. Controlling this via a
Zed setting is more convenient.
This does not modify the design of the titlebar in any way. It only
moves the existing option from an environment variable to a Zed setting.
Fixes#14165

Now that we have two surface areas that open as separate windows, it's
important they're consistent with one another. This PR make the settings

fundamentally the same design (nav on the left and content on the
right).

This refactors when we resolve UI keybindings in an effort to reduce
flickering whilst painting these: Previously, we would always resolve
these upon creating the binding. This could lead to cases where the
corresponding context was not yet available and no binding could be
resolved, even if the binding was then available on the next presented
frame. Following that, on the next rerender of whatever requested this
keybinding, the keybind for that context would then be found, we would
render that and then also win a layout shift in that process, as we went
from nothing rendered to something rendered between these frames.
With these changes, this now happens less often, because we only look
for the keybinding once the context can actually be resolved in the
window.

Also reduced cloning in the keymap editor in this process, since that
requiered changing due to this anyway.
Release Notes:
- Fixed some cases where keybinds would appear with a slight delay,
causing a flicker in the process
We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

The rules panel on the rules library window was rendering a black
background when the `panel.background` property on the active theme had
some level of transparency (for example `1917264D` on `nightfox` theme).

`theme_overrides` on settings:

This PR adds UI improvements to clarify the concept of "default rules"
and how they separate from regular rules. This is mostly motivated by
the issue linked above, where it clarified that the star icon was
communicating a "favoriting" affordance, which is not correct with how
rules work in Zed. When you tag/attach a rule as default, it will always
be included in every prompt, together with the agent's system prompt and
project rules (if they exist).
Hopefully, this will make understanding better. Here's how it looks like
now?
https://github.com/user-attachments/assets/435d3af7-e8a6-4646-8f00-94a409bd5f42
Release Notes:
- Improve rules library UI to better communicate the concept of default
rules vs. regular rules.
This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.
Release Notes:

This is really just a small beginning, as there are many other icons to
be revised and cleaned up. Our current set is a bit of a mess in terms

it all soon leading up to 1.0.

`EditorMode::SingleLine { auto_width: true }` was only used for the
title editor in the rules library, and following
https://github.com/zed-industries/zed/pull/31994 we can replace that
with a normal single-line editor without problems. The auto-width editor
was interacting badly with the recently-added newline visualization
code, causing a panic during layout---by switching it to
`Editor::single_line` the newline visualization works there too.
