Adds Claude Opus 4.8 for BYOK providers, including Anthropic fast-mode
handling and Bedrock/OpenCode model definitions.
Closes AI-336
Release Notes:
- Added Claude Opus 4.8 BYOK support
Update the behavior of both `editor: go to diagnostic` and `editor: go
to previous diagnostic` in order to ensure that, if there's a diagnostic
under the user's cursor that isn't active, it is first activated, with a
subsequent call jumping to the next or previous diagnostic,
respectively.
These changes also update how diagnostic activation handles the
situation when the global diagnostic renderer is not registered, as we
used to not update the active diagnostic group in that situation.
However, we now rely on it to determine whether the user's cursor is
already in the active diagnostic, with some tests now failing, so we now
default to an empty set of blocks for the active diagnostic group when
no global renderer is registered.
Release Notes:
- Update both `editor: go to diagnostic` and `editor: go to previous
diagnostic` to prefer activating the diagnostic under the cursor before
jumping to the next or previous diagnostic, respectively

## Summary
This started from #57636, after we saw ChatGPT subscription/Codex
requests stall over the past week. OpenCode v1.15.11 shipped related
resilience fixes for the same class of Codex subscription endpoint
issues, so this ports the relevant pieces into Zed's native ChatGPT
subscription provider.
When Zed asks ChatGPT/Codex for a response, sometimes the server
connection can get stuck before it even sends the first response
headers. Before this PR, Zed could wait indefinitely, which looks like
OpenCode/Zed “stalling.”
This PR makes Zed:
- Wait up to 10 seconds for the server to start responding.
- If nothing comes back in that window, treat it as a temporary
network/API failure.
- Let the existing retry logic try again instead of leaving the user
stuck.
- Send a stable session-id header so OpenAI’s Codex backend can
associate requests with the same Zed agent thread.
- Add tests to make sure:
- stuck-before-response requests time out,
- normal slow streaming responses are not cut off,
- ChatGPT subscription requests send the right session header,
- the agent retries this kind of failure.
intended user-facing result is: fewer “the assistant is just sitting
there forever” failures when using ChatGPT subscription models.
## Verification
- cargo test -p open_ai responses
- cargo test -p language_models openai_subscribed
- cargo test -p agent test_send_retry_on_http_send_error
- cargo check -p open_ai
- cargo check -p language_models
- cargo check -p agent
Release Notes:
- Fixed ChatGPT subscription requests stalling indefinitely before
response headers arrive.

When importing settings from VS Code, the minimap is now enabled by
default (matching VS Code's behavior) even if the user hasn't explicitly
set minimap-related options in their VS Code settings.json.
Previously, if `editor.minimap.enabled` and `editor.minimap.autohide`
were absent from the VS Code config, Zed would leave minimap at its own
default ("never"). Since VS Code defaults to minimap on, this caused a
mismatch for users expecting their VS Code experience to carry over.
Closes#56297

- Fixed apply VS Code minimap default when importing settings

Adds opt-in rendering for Markdown frontmatter metadata blocks in
Markdown Preview and agent markdown.
- Simple `key: value` metadata blocks now render as a two-column table,
while more complex metadata falls back to a code-style block.
- Metadata block content and key/value rows are parsed in the parser
step, and the request layout simply takes over rendering.

Provide a way to prevent GPUI from creating AccessKit adapters, and
enable this in Zed.
This will allow us to test AccessKit support in Zed without rolling it
out more broadly, while we gain confidence in the implementation in
GPUI.
I've also added a log statement
## Motivation (i.e. a mini post-mortem about the #56065 panics)
Merging #56065 caused some nasty panics in nightly. This was caused by a
bug in the logic for selecting a focus node for a `TreeUpdate`.
AccessKit panics when an invalid `TreeUpdate` is provided.
My assumption was that, since Zed uses no a11y APIs, and also that
essentially 0 zed users would have AT apps running, that merging this PR
would have no effect on the behaviour of Zed itself. However, two issues
combined to cause the panics:
- It seems like many people (everyone?) on mac gets the activation
callback called by accesskit_macos. A quick search suggests this might
be due to password managers searching for password fields, but not sure
how true that is.
- The bug in question related to *forgetting to check* whether a node
used a11y APIs, so we *were* pushing non-empty `TreeUpdate`s
As a (probably temporary) defensive measure, I added a function to try
to detect the bad cases and fix them. But it would be lovely if this
could live in AccessKit itself, since it would mean we wouldn't have to
do the check twice (once in GPUI, once in AccessKit). This would also
help prevent drift when updating accesskit versions if new invariants
are added.
We also cannot protect against this with `catch_unwind`, since we use
`panic=abort`. So our only option unfortunately is to temporarily
disable AccessKit until we know our implementation is stable.

Closes#56357
Release Notes:
- Fixed bug where devcontainers were not respecting override_command
Selecting text inside the hover documentation or git popups did not
scroll the popup when the drag passed the visible area, so any text
below the area could not be selected with the mouse.
The popup's container already had a `ScrollHandle` wired to its
scrollbar and wheel scrolling, but the inner `MarkdownElement` was
constructed without one. That left it in the default
`AutoscrollBehavior::Propagate` mode, which routes drag-autoscroll
requests to the editor-wide autoscroll listener, which is a listener
that does not exist inside a floating popover, so the requests were
silently dropped.
Passing the popup's existing `ScrollHandle` into the `MarkdownElement`
switches it to `AutoscrollBehavior::Controlled`, which scrolls the
popup's own container directly during a drag. The markdown preview view
already uses this same pattern.
Release Notes:
- Fixed hover documentation and git popups not scrolling while selecting
text with the mouse

I ran into this while using lazygit: the Shift navigation keys were
being captured by Zed to scroll the terminal buffer instead of being
passed through to the program.
Capturing them makes sense in the normal terminal case, where the user
wants to scroll and Shift has no other meaning. But in alternate-screen
TUIs like lazygit, less, or neovim, terminal scrollback isn't relevant,
so we can forward these keys to the program while it's open.
Release Notes:
- Fixed Shift+Up, Shift+Down, Shift+Home, and Shift+End in terminal TUIs
like lazygit, less, and neovim.

Stacked on top of #57430.
When the `sandboxing` feature flag is on (macOS only), agent-run
terminal commands are launched under `/usr/bin/sandbox-exec` with a
per-command Seatbelt policy:
- **Reads:** any path on the filesystem.
- **Writes:** each project worktree plus a per-command `$TMPDIR`.
- **Network:** blocked.
The model can request relaxations on individual calls via three new
input flags on the `terminal` tool:
- `allow_network: true`
- `allow_fs_write: true`
- `unsandboxed: true`
Each one triggers a separate always-prompt user approval (bypassing any
`always_allow` rules, since escalation is a stronger trust boundary than
the baseline command approval). The flags are silently ignored when
sandboxing is off, so the model can't surreptitiously change runtime
behavior by setting them in the no-op case.
The per-command tempdir is provisioned regardless of sandbox state so
the model can't infer whether the sandbox is in effect by looking at
`$TMPDIR`.
The Seatbelt config file's lifetime is tied to the `Terminal` entity via
an opaque RAII handle (`SandboxConfigHandle = Box<dyn Any + Send>`), so
cancellation paths drop it automatically.
### Notes for review
- The writable scope passed to the sandbox is the project's worktree
paths plus the per-command tempdir, **not** the resolved `cd` working
directory — `cd` is model-controlled, and using it as the writable scope
would let the model widen its own write permissions outside the project.
- The new tool flags are always present in the JSON schema (with
`#[serde(default)]`), even when the sandbox prompt section isn't
rendered. The system prompt only documents them when the section is
present, so the model shouldn't try to use them when it's not — but the
schema doesn't actively reject them, just ignores them.
- I opted not to add an end-to-end test for the escalation prompt path:
the existing `FakeThreadEnvironment` ignores the new params and toggling
the feature flag in tests is more wiring than felt worth it for a first
cut. The pure-function pieces (`sandbox_approval_title`, schema,
deserialization) are covered, and the sandbox crate itself has
end-to-end tests that actually invoke `sandbox-exec`.

Stacked on top of #57429.
Adds a new `sandboxing` feature flag (off for staff by default) and a
single source-of-truth helper `sandboxing_enabled(cx) = cfg!(target_os =
"macos") && cx.has_flag::<SandboxingFeatureFlag>()`. When the helper
returns true, the agent's system prompt gains a new `## Terminal
sandbox` section that:
- Lists each worktree's absolute path as a writable directory.
- Describes the per-command `$TMPDIR` scratch directory.
- States that outbound network access is blocked.
- Documents the three per-command flags (`allow_network`,
`allow_fs_write`, `unsandboxed`) the model can request to relax the
sandbox.
- Tells the model the section is stable for the duration of the
conversation.
When the flag is off, the section is omitted entirely — no mention of
sandboxing at all.
No behavior change to terminal execution yet; that's the next PR in the
stack.
Three new tests cover: section omitted when `sandboxing: false`, section
rendered with all worktrees + flag docs when `sandboxing: true`, and the
zero-worktrees case.

Closes#24070
Upgrades git2 from 0.20.1 to 0.21.0 with the `unstable-sha256` feature -
adds ability to open and work with git repositories using the SHA-256
object format. `Oid::from_str` now detects 64-char hex strings to parse
SHA-256 OIDs correctly.
Also adapts to breaking API changes in 0.21.0:
`Remote::url()` and `Commit::message()` both now return `Result`.
Release Notes:
- Added support for opening SHA-256 object format git repositories
Adds a new `sandbox` crate that wraps shell invocations under macOS's
`sandbox-exec(1)` with a Seatbelt policy built from per-command
permissions:
- Reads are unrestricted.
- Writes are restricted to a caller-provided list of directories (plus
the standard `/dev/*` write targets).
- Network access and unrestricted filesystem writes must be opted into
per command.
`wrap_invocation(program, args, writable_dirs, permissions)` returns the
new program/args plus a `SeatbeltConfigFile` RAII handle that deletes
the on-disk policy file when dropped — callers hold it for the lifetime
of the spawned command.
No callers yet — this is the first of three stacked PRs. The second
wires the sandbox state into the agent's system prompt behind a feature
flag; the third wires the actual wrapping into the agent terminal tool.
The macOS-only dependencies (`tempfile`, `anyhow`) are gated by
`target.'cfg(target_os = "macos")'` so the crate is empty on other
platforms.
Includes 14 tests covering both the generated Seatbelt policy text and
end-to-end behavior (actually invoking `sandbox-exec` and asserting
reads/writes succeed or fail per policy).

Follow-up to #57772.
While comparing the `edit_file_tool_streaming/medium_insertions`
benchmark in Criterion and xctrace, I noticed the DP scoring loop was
spending most of its time on inlined `Matrix::get`/`Matrix::set` access
in `StreamingDiff::push_new`.
This changes the loop to split the previous and current score columns
once per DP column and then index those column slices directly. This
keeps the scoring algorithm the same, but hoists the column offset
calculation out of the inner loop and gives the compiler clearer
aliasing information between the immutable previous column and mutable
current column.
In xctrace, the hottest DP scoring line dropped from 10,407 samples
before to 9,409 samples after on
`edit_file_tool_streaming/medium_insertions`, and total
`StreamingDiff::push_new` leaf samples dropped from 10,800 to 9,822.
This is consistently faster in the end-to-end `edit_file_tool`
benchmark, and gives a small speed-up for the targeted workload without
changing the scoring algorithm.
### Results
Benchmarked with `release-fast` against a clean baseline using
Criterion’s `before_slice` baseline.
#### `streaming_diff_push_new`
| Fixture | Before median | After median | Change |
| --- | ---: | ---: | ---: |
| `tiny_function_rewrite` | `7.6317 ms` | `6.4951 ms` | 10.8% faster |
| `small_function_rewrite` | `45.961 ms` | `44.839 ms` | No significant
change |
| `medium_many_small_changes` | `99.694 ms` | `104.83 ms` | 5.2% slower
|
| `medium_insertions` | `95.909 ms` | `83.093 ms` | 13.5% faster |
#### `edit_file_tool_streaming`
| Fixture | Before median | After median | Change |
| --- | ---: | ---: | ---: |
| `tiny_function_rewrite` | `1.1110 ms` | `1.0617 ms` | 7.1% faster |
| `small_function_rewrite` | `2.4554 ms` | `2.2751 ms` | 7.1% faster |
| `medium_many_small_changes` | `87.272 ms` | `77.065 ms` | 11.5% faster
|
| `medium_insertions` | `92.469 ms` | `87.478 ms` | 5.9% faster |
The lower-level `streaming_diff_push_new` benchmark is mixed, but the
end-to-end `edit_file_tool_streaming` workload improves across all
fixtures.

This PR is a follow-up to #54206 to make it so we only respect the
feature flag overrides for Zed staff (or when running a development
build).
Previously just the UI portion of the feature flags was disabled for
non-staff, but manipulating the settings file by hand would still allow
setting overrides that would be respected.
The only other setting on the "Developer" page of the settings UI was
the performance profiler. This was previously only available for staff,
as the entire "Developer" page was limited to staff, but it seems
reasonable to allow non-staff to see this.

UTF-8 character. Round split points up to the next char boundary and

Release Notes:
- Fixed a crash when deleting words near inline diff boundaries

## Motivation
Miniprofs of Zed dropping frames showed foreground thread stalls of
711.56 ms, 641.01 ms, and 221.99 ms from the `edit_file_tool`. The new
benchmark isolated `StreamingDiff::push_new` as one of the expensive
phases so this PR aims to speed it up so we can avoid dropping more
frames in the future.
## Benchmark methodology
I had an agent create a Criterion suite with four deterministic Rust
edit fixtures: tiny localized rewrite, small localized rewrite, many
small changes, and helper block insertions.
Benchmarked with:
```sh
cargo bench -p streaming_diff --bench streaming_diff --profile release-fast -- --warm-up-time 1 --measurement-time 2
```
The benchmark binary was also recorded under `xctrace` CPU Counters to
inspect CPU samples before and after the change.
## Results
`StreamingDiff::push_new` improved across all fixtures:
| Benchmark | Before | After | Improvement |
|---|---:|---:|---:|
| `tiny_function_rewrite` | ~10.81 ms | ~6.91 ms | ~36% faster |
| `small_function_rewrite` | ~51.02 ms | ~35.39 ms | ~31% faster |
| `medium_many_small_changes` | ~130.71 ms | ~83.83 ms | ~36% faster |
| `medium_insertions` | ~120.52 ms | ~79.90 ms | ~34% faster |
The `xctrace` baseline showed samples in `Hash::hash`,
`RandomState::hash_one`, `HashMap::insert`, and
`RawTable::reserve_rehash`. After replacing the map with two `Vec<u32>`
row buffers, the hash table frames disappeared from the top samples.
The speedup comes from removing hash work from the DP inner loop and
replacing scattered hash table probes with contiguous row buffer access
(better cache hits 🏎️). The trace did not include direct cache miss
counts, but this layout is likely more cache friendly because it
replaces hash table access with a continuous line of memory (the
`Vec`s).

## Summary
- Track existing skill file contents and instruction bodies before
migrating Rules to Skills
- Skip writing migrated skills when an equivalent skill already exists
- Cover duplicate detection across differently named skills
## Tests
- cargo test -p prompt_store rules_to_skills_migration
Release Notes:
- Fixed duplicate Skills being created when migrating Rules.
Until now, the cloud-hosted model list was only refreshed in response to
events that exercise the LLM token (a `UserUpdated` push, an
organization change, or `PrivateUserInfoUpdated`). If a user wasn't
actively using AI features around the time we shipped new models, the
list could stay stale until they restarted Zed.
This is the second step toward fixing that, after #57078 made the cloud
websocket reconnect on its own. We now treat each successful (re)connect
as a hint that the server state may have changed, so possibly new model
definitions will be available, and trigger a model list refresh.
The trigger is a new `Client::cloud_connection_id()` watch that bumps a
counter each time the websocket handshake completes.
`CloudLanguageModelProvider::State` subscribes to it and, on every tick
after the initial `0`, schedules a debounced refresh (with jitter, so we
don't have all active clients trying to reconnect at the same time after
we deploy in cloud).
Closes CLO-713.
Release Notes:
- The list of Zed hosted models is now refreshed automatically, without
requiring a restart

Add command palette actions for opening global and project-specific
AGENTS.md files
Closes AI-324
Release Notes:
- Added commands to open global and project-specific AGENTS.md rules
Stop trying to add new watches for 5 seconds after receiving the "OS
file watch limit reached" error.
This was flooding the logs and many pointless syscalls.
Related to #57422, #57042, FR-18
Release Notes:
- Improved file watcher behavior when the OS file watch limit is
reached.
Closes#47251
Fix dot (`.`) repeat not correctly repeating the last change after
replaying a macro (`@register`)
([#47251](https://github.com/zed-industries/zed/issues/47251))
When replaying a macro that contains text insertions,
`replay_insert_event` calls `handle_input` directly and never emits
`InputHandled`, so the `observe_insertion` subscription never fires.
This left the dot register stale — `.` after `@register` would repeat an
earlier change instead of the last one made by the macro.
Fix by calling `observe_insertion` explicitly in the
`ReplayableAction::Insertion` branch of `Replayer::next`.
Release Notes:
- Fixed dot (`.`) repeat not repeating the last change made by a macro
(`@register`).
