Opens .ipynb files in a native notebook editor, in a project or LightEdit.
- crates/ide-notebook: lossless nbformat documents (unchanged notebooks save byte-for-byte, unknown fields kept, external changes detected) and owned local kernels over ZMQ via kernelspec — the selected Python environment only needs ipykernel, no Jupyter server.
- ide-host owns notebook documents per project incarnation and admits one execution batch at a time; outputs stream over IPC channels and kernel status is an IdeEvent.
- src/features/notebook: virtualized Python/Markdown cells, insert/delete/move/change type, Run Cell / Run All (Shift+Enter), interrupt, restart, interpreter selection from ide-sdk discovery, shared split views. Raw/unknown cells stay read-only.
- Custom editor kinds take part in dirty state, save/save all, undo/redo and Save/Don't Save/Cancel; closing editors from other features awaits that decision.
- Outputs: text, tracebacks, PNG/JPEG and sanitized SVG inline; HTML sanitized in a sandboxed iframe without allow-same-origin; JavaScript output is shown as inert source.
- Explicit launches (opening a notebook from the OS) win over session restoration.
Closes#131

The font pickers never read the installed fonts: they probed a hard-coded list of ~30 names with canvas width checks, so anything outside the list never appeared and the monospaced filter changed nothing. A new ide-fonts crate asks the platform font system for families and their fixed-pitch flag (CoreText on macOS, DirectWrite on Windows, fc-list on Linux/BSD), exposed as system_font_families (spawn_blocking, cached). Every font picker — editor font and fallback, terminal font and fallback, UI custom font — uses one FontSelect with prefix type-ahead, a real monospaced filter, and keeps an uninstalled selection visible.
Not verified on Windows or Linux machines.
Fixes#199

Language servers can be configured from settings.toml (global or project) and Settings › Language Servers: arguments, environment, initialization options and workspace settings per server, enable/disable, and any stdio LSP server can be added for a language. Settings-only changes are pushed with workspace/didChangeConfiguration; launch changes restart the server.
Also: re-enabling a server now detaches and stops the fallback that stood in for it, and a server added from the dialog is written as its own [languageServers.<name>] table.

## What
An Agents feature: hand a task to a coding agent and follow it from the IDE. Agents speak the [Agent Client Protocol](https://agentclientprotocol.com). Built in: Claude Code, Codex, Gemini CLI, GitHub Copilot, Cursor, OpenCode, Qwen Code, Kimi CLI, Goose, Auggie, Kiro, Mistral Vibe. You can add your own in `<config>/agents/<id>.toml` (`name`, `command`, `args`, `[env]`). An agent whose command isn't on `PATH` is listed under "Not installed".
- **New Task page.** An editor page with a prompt box. You pick the agent, model, mode and thinking effort, and whether it runs in a new worktree (from a chosen branch) or in the checkout.
- **Agents tool window.** Tasks are grouped by what they need: Needs Input, Failed, Running, Ready to Review, Archived. It also shows a stripe badge, a status bar item and notifications.
- **Session tab.**
- The conversation: Markdown, thinking, tool calls with diff stats, the plan.
- Permission requests appear as an editor banner.
- The changed files are compared against the task's base commit and open in the diff viewer.
- A context-usage meter.
- **Composer.**
- `@` references files from the project index. A referenced file's text is sent when the agent accepts embedded context, otherwise a `resource_link`.
- `/` lists the agent's commands; ↑/↓ recall earlier messages.
- Images can be pasted, dropped or picked; Shift+Tab cycles the mode.
- While the agent works, Enter queues the message and ⌘↵ interrupts the turn and sends it now. Queued messages can be sent now, edited or removed.
- **Send to Agent.** In the editor and Project view context menus. It adds `@file:10-20` references to the message you typed last.
- Landing the work is left to the existing Git features: the worktree is a normal branch.
## How
- **`crates/ide-agent`**: one ACP agent process per task, running in the task's directory.
- It folds `session/update` into a timeline and answers `session/request_permission`.
- It tracks the session's settings: `configOptions`, falling back to the older `modes` / `models` fields. The user's choices are applied again on every new or reloaded session.
- Tasks are saved as JSON per task. Sessions resume with `session/load` without duplicating history, and old task files are upgraded when read.
- **`ide-jsonrpc`**: adds newline-delimited framing (ACP) next to Content-Length (LSP).
- **`ide-vcs`**: adds `numstat_with_worktree` for the changes list.
- **Editor**:
- The Switcher (⌃⇥) lists every open editor, as IDEA does, not just files.
- `EditorKindContribution.restorable` lets a kind's tabs be saved with the editor session, so agent tabs survive reloads.
- **UI**: `Select` popups now size to fit short option details (they used to cut them off).
## Testing
- `cargo test -p ide-agent` (14 tests). They use an in-memory ACP agent and cover permissions, restart with `session/load`, settings, the queue with send-now and stop, and prompt blocks.
- There is also an ignored end-to-end test against the real Claude Code adapter: `OPENIDEA_AGENT_E2E=1 cargo test -p ide-agent real_claude -- --ignored`.
- `pnpm vitest run`: 2052 tests.
- `cargo clippy -p ide-agent -p openidea --all-targets -- -D warnings` and typecheck are clean.
- Driven in the running app with Claude Code:
- A task in a worktree, with permission answers, changes listed and the diff opened.
- A follow-up after restarting the IDE.
- `@` reference with embedded content, `/` commands, Shift+Tab mode changes.
- A queued message and send-now, an image prompt, Send to Agent from a selection.
- The Switcher and restored tabs after a reload.
Not covered yet: only Claude Code was driven end to end. The other agents go through the same ACP path but weren't run here.
Merged on the maintainer's go-ahead. Merge with main: kept both sides in Cargo.toml (ide-agent + ide-clipboard), the feature registry (agents + vim) and zh.json (no duplicate keys). After the merge: typecheck clean, full vitest 268 files / 2247 tests passed, ide-agent/ide-jsonrpc/ide-vcs 144 passed, bindings unchanged after regeneration.
Exchange files with the OS clipboard on Windows: CF_HDROP read/write in a new ide-clipboard crate (Win32 FFI behind cfg(windows), stub elsewhere), three thin commands, and project-view copy/paste hooks. Pasting from Explorer always copies; our own hand-off falls back to the internal clipboard so Copy/Move dialogs and refactoring stay intact.
Verified: ide-clipboard round-trip tests, project-tree vitest (93), CI on all three OSes. Not verified on Windows hardware here.
