## Summary
Addresses #16965
This PR adds support for **opening and saving** files with legacy
encodings (non-UTF-8).
Previously, Zed failed to open files encoded in Shift-JIS, EUC-JP, Big5,
etc., displaying a "Could not open file" error screen. This PR
implements automatic encoding detection upon opening and ensures the
original encoding is preserved when saving.
## Implementation Details
1. **Worktree (Loading)**:
* Updated `load_file` to use `chardetng` for automatic encoding
detection.
* Files are decoded to UTF-8 internal strings for editing, while
preserving the detected `Encoding` metadata.
2. **Language / Buffer**:
* Added an `encoding` field to the `Buffer` struct to store the detected
encoding.
3. **Worktree (Saving)**:
* Updated `write_file` to accept the stored encoding.
* **Performance Optimization**:
* **UTF-8 Path**: Uses the existing optimized `fs.save` (streaming
chunks directly from Rope), ensuring no performance regression for the
vast majority of files.
* **Legacy Encoding Path**: Implemented a fallback that converts the
Rope to a contiguous `String/Bytes` in memory, re-encodes it to the
target format (e.g., Shift-JIS), and writes it to disk.
* *Note*: This fallback involves memory allocation, but it is necessary
to support legacy encodings without refactoring the `fs` crate's
streaming interfaces.
## Changes
- `crates/worktree`:
- Add dependencies: `encoding_rs`, `chardetng`.
- Update `load_file` to detect encoding and decode content.
- Update `write_file` to handle re-encoding on save.
- `crates/language`: Add `encoding` field and accessors to `Buffer`.
- `crates/project`: Pass encoding information between Worktree and
Buffer.
- `crates/vim`: Update `:w` command to use the new `write_file`
signature.
## Verification
I validated this manually using a Rust script to generate test files
with various encodings.
**Results:**
* ✅ **Success (Opened & Saved correctly):**
* **Japanese:** `Shift-JIS` (CP932), `EUC-JP`, `ISO-2022-JP`
* **Chinese:** `Big5` (Traditional), `GBK/GB2312` (Simplified)
* **Western/Unicode:** `Windows-1252` (CP1252), `UTF-16LE`, `UTF-16BE`
* ⚠️ **limitations (Detection accuracy):**
* Some specific encodings like `KOI8-R` or generic `Latin1` (ISO-8859-1)
may partially display replacement characters (`?`) depending on the file
content length. This is a known limitation of the heuristic detection
library (`chardetng`) rather than the saving logic.
Release Notes:
- Added support for opening and saving files with legacy encodings
(Shift-JIS, Big5, etc.)

Closes #ISSUE
This PR is rather a nice to have change than anything critical, so
review priority should remain low.
Switch to using `semver::Version` for representing node binary and npm
package versions. This is in an effort to root out implicit behavior and
improve type safety when interacting with the `node_runtime` crate by
catching invalid versions where they appear. Currently Zed may
implicitly assume the current version is correct, or always install the
newest version when a invalid version is passed. `semver::Version` also
doesn't require the heap, which is probably more of a fun fact than
anything useful.
`npm_install_packages` still takes versions as a `&str`, because
`latest` can be used to fetch the latest version on npm. This could
likely be made into an enum as well, but would make the PR even larger.
I tested changes with some node based language servers and external
agents, which all worked fine. It would be nice to have some e2e tests
for node. To be safe I'd put it on nightly after a Wednesday release.

## Summary
This PR adds support for the MCP (Model Context Protocol)
`notifications/tools/list_changed` notification, enabling dynamic tool
discovery when MCP servers add, remove, or modify their available tools
at runtime.
## Release Notes:
- Improved: MCP tools are now automatically reloaded when a context
server sends a `tools/list_changed` notification, eliminating the need
to restart the server to discover new tools.
## Changes
- Register a notification handler for `notifications/tools/list_changed`
in `ContextServerRegistry`
- Automatically reload tools when the notification is received
- Handler is registered both on initial server startup and when a server
transitions to `Running` status
## Motivation
The MCP specification includes a `notifications/tools/list_changed`
notification to inform clients when the list of available tools has
changed. Previously, Zed's agent would only load tools once when a
context server started. This meant that:
1. If an MCP server dynamically registered new tools after
initialization, they would not be available to the agent
2. The only way to refresh tools was to restart the entire context
server
3. Tools that were removed or modified would remain in the old state
until restart
## Implementation Details
The implementation follows these steps:
1. When a context server transitions to `Running` status, register a
notification handler for `notifications/tools/list_changed`
2. The handler captures a weak reference to the `ContextServerRegistry`
entity
3. When the notification is received, spawn a task that calls
`reload_tools_for_server` with the server ID
4. The existing `reload_tools_for_server` method handles fetching the
updated tool list and notifying observers
This approach is minimal and reuses existing tool-loading
infrastructure.
## Testing
- [x] Code compiles with `./script/clippy -p agent`
- The notification handler infrastructure already exists and is tested
in the codebase
- The `reload_tools_for_server` method is already tested and working
## Benefits
- Improves developer experience by enabling hot-reloading of MCP tools
- Aligns with the MCP specification's capability negotiation system
- No breaking changes to existing functionality
- Enables more flexible and dynamic MCP server implementations
## Related Issues
This implements part of the MCP specification that was already defined
in the type system but not wired up to actually handle the
notifications.

This PR solves my main pain point with Zed agent: I have a long list of
available models from different providers, and I switch between a few of
them depending on the context and the project. In particular, I use the
same models from different providers depending on whether I'm working on
a personal project or at my day job. Since I only care about a few
models (none of which are in "recommended") that are scattered all over
the list, switching between them is bothersome, even using search.
This change adds a new option in `settings.json`
(`agent.favorite_models`) and the UI to manipulate it directly from the
list of available models. When any models are marked as favorites, they
appear in a dedicated section at the very top of the list. Each model
has a small icon button that appears on hover and allows to toggle
whether it's marked as favorite.
I implemented this on the UI level (i.e. there's no first-party
knowledge about favorite models in the agent itself; in theory it could
return favorite models as a group but it would make it harder to
implement bespoke UI for the favorite models section and it also
wouldn't work for text threads which don't use the ACP infrastructure).
The feature is only enabled for the native agent but disabled for
external agents because we can't easily map their model IDs to settings
and there could be weird collisions between them.

Closes https://github.com/zed-industries/zed/issues/31507
Release Notes:
- Added the ability to mark language models as favorites and pin them to
the top of the list. This feature is available in the native Zed agent
(including text threads and the inline assistant), but not in external
agents via ACP.

Closes https://github.com/zed-industries/zed/issues/12589
Forces Zed to require user permissions before running any basic
potentially dangerous actions: parsing and synchronizing
`.zed/settings.json`, downloading and spawning any language and MCP
servers (includes `prettier` and `copilot` instances) and all
`NodeRuntime` interactions.
There are more we can add later, among the ideas: DAP downloads on
debugger start, Python virtual environment, etc.
By default, Zed starts in restricted mode and shows a `! Restricted
Mode` in the title bar, no aforementioned actions are executed.
Clicking it or calling `workspace::ToggleWorktreeSecurity` command will
bring a modal to trust worktrees or dismiss the modal:
<img width="1341" height="475" alt="1"
src="https://github.com/user-attachments/assets/4fabe63a-6494-42c7-b0ea-606abb1c0c20"
/>
Agent Panel shows a message too:
<img width="644" height="106" alt="2"
src="https://github.com/user-attachments/assets/0a4554bc-1f1e-455b-b97d-244d7d6a3259"
/>
This works on local, SSH and WSL remote projects, trusted worktrees are
persisted between Zed restarts.
There's a way to clear all persisted trust with
`workspace::ClearTrustedWorktrees`, this will restart Zed.
This mechanism can be turned off with settings:
```jsonc
"session": {
"trust_all_worktrees": true
}
```
in this mode, all worktrees will be trusted by default, allowing all
actions, but no auto trust will be persisted: hence, when the setting is
changed back, auto trusted worktrees will require another trust
confirmation.
This settings switch was added to the onboarding view also.
Release Notes:
- Introduced worktree trust mechanism, can be turned off with
`"session": { "trust_all_worktrees": true }`

Hi,
This PR fixes nothing. I just miss the option to open recent projects
quickly upon opening Zed, so I made this. Hope I can see it soon in
Preview channel.
If there is any suggestion, just comment. I will take it seriously.
Thank you!

Release Notes:
- Added a new value to the `restore_on_startup` setting called
`launchpad`. This value makes Zed open with a variant of the welcome
screen ("the launchpad") upon startup. Additionally, this same page
variant is now also what is displayed if you close all tabs in an
existing window that doesn't contain any folders open. The launchpad
page shows you up to 5 recent projects, making it easy to open something
you were working recently.

## Fix incorrect directory path folding in slash command file collection
**Description:**
This PR fixes a bug in the `collect_files` function where the directory
folding logic (used to compact chains like `.github/workflows`) failed
to reset its state when traversing out of a folded branch.
**The Issue:**
The `folded_directory_names` accumulator was persisting across loop
iterations. If the traversal moved from a folded directory (e.g.,
`.github/workflows`) to a sibling directory (e.g., `.zed`), the sibling
would incorrectly inherit the prefix of the previously folded path,
resulting in incorrect paths like `.github/.zed`.
**The Fix:**
* Introduced `folded_directory_path` to track the specific path
currently being folded.
* Added a check to reset `folded_directory_names` whenever the traversal
encounters an entry that is not a child of the currently folded path.
* Ensured state is cleared immediately after a folded directory is
rendered.
**Release Notes:**
- Fixed an issue where using slash commands to collect files would
sometimes display incorrect directory paths (e.g., showing
`.github/.zed` instead of `.zed`) when adjacent directories were
automatically folded.

This PR adds a staff-only button to the edit prediction menu for
capturing your current editing session as edit prediction example file.
When you click that button, it opens a markdown tab with the example. By
default, the most recent change that you've made is used as the expected
patch, and all of the previous events are used as the editing history.

Release Notes:

Fix a bug where the branch picker would be dismissed before completing
the add remote flow, thus making Zed unable to add remote repositories
through the branch picker.
This bug was caused by the picker always being dismissed on the confirm
action, so the fix was stopping the branch modal from being dismissed
too early.
I also cleaned up the UI a bit and code.
1. Removed the loading field from the Branch delegate because it was
never used and the activity indicator will show remote add command if it
takes a while.
2. I replaced some async task spawning with the use of `cx.defer`.
3. Added a `add remote name` fake entry when the picker is in the name
remote state. I did this so the UI would be consistent with the other
states.
4. Added two regression tests.
4.1 One to prevent this bug from occurring again:
https://github.com/zed-industries/zed/pull/44742
4.2 Another to prevent the early dismissal bug from occurring
5. Made `init_branch_list_test` param order consistent with Zed's code
base

Closes#21324
Adds four new commands:
- `markdown::MoveUp`, `markdown::MoveDown` - these scroll up and down in
markdown preview mode, by no more than the height of a large headline.
- `markdown::MoveUpByItem`, and `markdown::MoveDownByItem` - these
scroll up and down by the height of the item at the top of the markdown
preview window. So headlines and large codeblocks, for instance, scroll
further than individual paragraph lines.
Also attempts to create sensible defaults:
`down` -> `markdown::ScrollDown`
`up` -> `markdown::ScrollUp`
`alt-down` -> `markdown::ScrollDownByItem`
`alt-up` -> `markdown::ScrollUpByItem`
And in Vim:
`ctrl-u` -> `markdown::ScrollPageUp`
`ctrl-d` -> `markdown::ScrollPageDown`
`ctrl-e` -> `markdown::ScrollDown`
`ctrl-y` -> `markdown::ScrollUp`
Release Notes:
- Added commands `markdown::ScrollUp`, `markdown::ScrollDown`,
`markdown::ScrollUpByItem`, and `markdown::ScrollDownByItem`
- Changed commands `markdown::MovePageUp` to `markdown::ScrollPageUp`
and `markdown::MovePageDown` to `markdown::ScrollPageDown`

This PR restructures the commands of the Edit Prediction CLI (now called
`ep`), to support some flows that are important for the training
process:
* generating zeta2 prompt and expected output, without running
predictions
* scoring outputs that are generated by a system other than the
production code (to evaluate the model during training)
To achieve this, we've restructured the CLI commands so that they all
take as input, and produce as output, a consistent, uniform data format:
a set of one or more `Example` structs, expressible either as the
original markdown format, or as a JSON lines. The `Example` struct
starts with the basic fields that are in human-readable eval format, but
contain a number of optional fields that are filled in by different
steps in the processing pipeline (`context`, `predict`, `format-prompt`,
and `score`).
### To do
* [x] Adjust the teacher model output parsing to use the full buffer
contents
* [x] Move udiff to cli
* [x] Align `format-prompt` with Zeta2's production code
* [x] Change score output to assume same provider
* [x] Move pretty reporting to `eval` command
* [x] Store cursor point in addition to cursor offset
* [x] Rename `edit_prediction_cli2` -> `edit_prediction_cli` (nuke the
old one)

Partially addresses #11473
MVP of dev containers with the following capabilities:
- If in a project with `.devcontainer/devcontainer.json`, a pop-up
notification will ask if you want to open the project in a dev
container. This can be dismissed:
<img width="1478" height="1191" alt="Screenshot 2025-12-08 at 3 15
23 PM"
src="https://github.com/user-attachments/assets/ec2e20d6-28ec-4495-8f23-4c1d48a9ce78"
/>
- Similarly, if a `devcontainer.json` file is in the project, you can
open a devcontainer (or go the devcontainer.json file for further
editing) via the `open remote` modal:
https://github.com/user-attachments/assets/61f2fdaa-2808-4efc-994c-7b444a92c0b1
*Limitations*
This is a first release, and comes with some limitations:
- Zed extensions are not managed in `devcontainer.json` yet. They will
need to be installed either on host or in the container. Host +
Container sync their extensions, so there is not currently a concept of
what is installed in the container vs what is installed on host: they
come from the same list of manifests
- This implementation uses the [devcontainer
CLI](https://github.com/devcontainers/cli) for its control plane. Hence,
it does not yet support the `forwardPorts` directive. A single port can
be opened with `appPort`. See reference in docs
[here](https://github.com/devcontainers/cli/tree/main/example-usage#how-the-tool-examples-work)
- Editing devcontainer.json does not automatically cause the dev
container to be rebuilt. So if you add features, change images, etc, you
will need to `docker kill` the existing dev container before proceeding.
- Currently takes a hard dependency on `docker` being available in the
user's `PATH`.
Release Notes:
- Added ability to Open a project in a DevContainer, provided a
`.devcontainer/devcontainer.json` is present

This fixes an issue where the snippet file location would not be the
proper one for compiled extensions because it would be populated with an
absolute path instead of a relative one in relation to the extension
output directory. This caused the copy operation downstream to not do
anything, because it copied the file to the location it already was
(which was not the output directory for that extension).
Also adds some tests and pulls in the `Fs` so we do not have such issues
with snippets a third time hopefully.

When installing local "dev" extensions that provide tree-sitter
grammars, compiling the parser can be quite intensive[^anecdote]. This
PR changes the logic to only compile the parser if the WASM object
doesn't exist or the source files are newer than the object (just like
`make(1)` would do).

compile and uses 20 GB of memory on my laptop.

This PR partially implements a knowledge distillation data pipeline.
`zeta distill` gets a dataset of chronologically ordered commits and
generates synthetic predictions with a teacher model (one-shot Claude
Sonnet).
`zeta distill --batches cache.db` will enable Message Batches API. Under
the first run, this command will collect all LLM requests and upload a
batch of them to Anthropic. On subsequent runs, it will check the batch
status. If ready, it will download the result and put them into the
local cache.
