+# xterm.js Copilot Instructions
+
+## Architecture Overview
+
+**Core Structure**: xterm.js is a multi-target terminal emulator with three main distributions:
+- `src/browser/`: Full-featured browser terminal with DOM rendering
+- `src/headless/`: Server-side terminal for Node.js (no DOM)
+- `src/common/`: Shared core logic (parsing, buffer management, terminal state)
+
+**Key Classes**:
+- `Terminal` (browser/headless): Public API wrapper
+- `CoreTerminal` (common): Core terminal logic and state
+- `CoreBrowserTerminal` (browser): Browser-specific terminal implementation
+
+## Development Workflow
+
+**Build System**:
+```bash
+npm run build && npm run esbuild # Build all TypeScript and bundle
+```
+
+**Testing**:
+- Unit tests: `npm run test-unit` (Mocha)
+- Unit tests filtering to file: `npm run test-unit -- **/fileName.ts
+- Per-addon unit tests: `npm run test-unit -- addons/addon-image/out-esbuild/*.test.js`
+- Integration tests: `npm run test-integration` (Playwright across Chrome/Firefox/WebKit)
+- Integration tests by file: `npm run test-integration -- test/playwright/InputHandler.test.ts`. Never use grep to filter tests, it doesn't work
+- Integration tests by addon: `npm run test-integration -- --suite=addon-search`. Suites always follow the format `addon-<something>`
+- Lint changes: `npm run lint-changes` to lint only changed files, `npm run lint-changes-fix` to fix them
+
+## Addon Development Pattern
+
+All addons follow this structure:
+```typescript
+export class MyAddon implements ITerminalAddon {
+  activate(terminal: Terminal): void {
+    // Called when loaded via terminal.loadAddon()
+    // Register handlers, access terminal APIs
+  }
+  dispose(): void {
+    // Cleanup when addon is disposed
+  }
+}
+```
+
+**Key Examples**:
+- `addons/addon-fit/`: Terminal sizing
+- `addons/addon-webgl/`: GPU-accelerated rendering
+- `addons/addon-search/`: Text search functionality
+
+## Project-Specific Conventions
+
+**TypeScript Project Structure**: Uses TypeScript project references (`tsconfig.all.json`) for incremental builds across browser/headless/addons.
+
+**API Design**: 
+- Browser and headless terminals share the same public API
+- Proposed APIs require `allowProposedApi: true` option
+- Constructor-only options (cols, rows) cannot be changed after instantiation
+
+**Testing Utilities**: Use `TestUtils.ts` helpers:
+- `openTerminal(ctx, options)` for setup
+- `pollFor(page, fn, expectedValue)` for async assertions
+- `writeSync(page, data)` for terminal input
+
+## Common Patterns
+
+**Parser Integration**: Register custom escape sequence handlers:
+```typescript
+terminal.parser.registerCsiHandler('m', params => {
+  // Handle SGR sequences
+  return true; // Handled
+});
+```
+
+**Buffer Access**: Read terminal content via buffer API:
+```typescript
+const line = terminal.buffer.active.getLine(0);
+const cell = line?.getCell(0);
+```
+
+**Events**: All terminals emit standard events (onData, onResize, onRender) plus platform-specific ones.
+
+## Critical Implementation Details
+
+- Terminal rendering uses either DOM or WebGL renderers
+- Buffer lines are immutable; create new instances for modifications
+- Character width handling supports Unicode 11+ and grapheme clustering
+- Mouse events translate web events to terminal protocols (X10, VT200, etc.)
+- Color theming supports both palette and true color modes
+
+## Writing unit tests
+
+- Unit tests live alongside the source code file of the thing it's testing with a .test.ts suffix.

+# Benchmark run instructions
+
+- Full suite: `npm run benchmark`
+- Single benchmark file:
+  - Tree: `npm run benchmark -- -t out-test/benchmark/Event.benchmark.js`
+  - Run file: `npm run benchmark -- -s "out-test/benchmark/Event.benchmark.js" out-test/benchmark/Event.benchmark.js`
+- Single context/case:
+  - Use `-t` to get the path, then:
+  - `npm run benchmark -- -s "<path>" out-test/benchmark/Event.benchmark.js`
+
+When writing instructions, use `RuntimeCase` to measure pure runtime in ms, use `ThroughputRuntimeCase` when measuring throughput in MB/s.
+
+Notes:
+- Benchmarks run from built JS in `out-test/benchmark/*.benchmark.js`.
+- Keep `NODE_PATH=./out` (handled by the npm script).

+When writing unit tests follow these rules:
+
+- When writing unit tests for addons, always create a real xterm.js instance instead of mocking it.
+- Prefer `assert.ok` over `assert.notStrictEqual` when checking something is undefined or not.
+- Avoid comments as most tests should be self-documenting.

+## Contributing code
+
+You can find issues to work on by looking at issues labeled with [help wanted](https://github.com/xtermjs/xterm.js/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22) or [good first issue](https://github.com/xtermjs/xterm.js/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22). It's a good idea to comment on the issue saying that you're looking into it, just in case someone else comes along and you duplicate work. Once you have your issue, here are the steps to contribute:
+
+- Fork [xterm.js](https://github.com/xtermjs/xterm.js/) ([how to fork a repo](https://help.github.com/articles/fork-a-repo)).
+- Get the [xterm.js demo](https://github.com/xtermjs/xterm.js/wiki/Contributing#running-the-demo) running.
+- Make the fix and verify it works in the demo. Be sure to follow thew general code style of the rest of the project.
+- If your changes are easy to test or likely to regress in the future, add tests. These could be unit or integration (playwright) tests.
+- Submit a pull request ([how to create a pull request](https://help.github.com/articles/fork-a-repo)).
+
+> ![TIP]
+> Don't put more than one feature or fix in a single pull request. The smaller pull requests are the easier they are to review and merge.
+
+By contributing code to xterm.js you:
+
+ - Agree to license the contributed code under xterm.js' [MIT license](LICENSE).
+ - Confirm that you have the right to contribute and license the code in question. This means that either you hold all rights on the code, or the rights holder has explicitly granted the right to use it like this, through a compatible open source license or through a direct agreement with you.

 ## Opening issues

 The preferred way to report bugs or request features is to use
-[GitHub issues](http://github.com/sourcelair/xterm.js/issues). Before
-opening an issue, read these pointers.
+[GitHub issues](http://github.com/xtermjs/xterm.js/issues).

-### Opening issues effectively
+### Creating great issues

- Include information about **the browser in which the problem occurred**. Even
-  if you tested several browsers, and the problem occurred in all of them,
-  mention this fact in the bug report. Also include browser version numbers and
-  the operating system that you're on.
+- Include information about **the browser in which the problem occurred** or the terminal being used. If you tested several browsers and the problem occurred in all of them, mention this fact in the bug report. Also include browser version numbers and the operating system that you're on.
+- Include the version of xterm.js being used, preferably either with the latest `beta` tagged release on npm or reproducing in the demo on the `master` branch.
+- Mention precisely what went wrong. What did you expect to happen? What happened instead? Describe the exact steps a maintainer has to take to make the problem occur.
+- If the problem can not be reproduced in the [demo of xterm.js](https://github.com/xtermjs/xterm.js/wiki/Contributing#running-the-demo), provide an HTML document that demonstrates the problem.
+- Be polite and follow [the code of conduct](https://github.com/xtermjs/xterm.js?tab=coc-ov-file#readme).

- Mention which release of xterm.js you're using. Preferably, try also with
-  the current HEAD of the master branch, to ensure the problem has not already been
-  fixed.
+### Issue triaging philosophy

- Mention precisely what went wrong. What did you expect to happen? What happened instead? Describe the
-  exact steps a maintainer has to take to make the problem occur.
+It's pretty common for maintainers of large open source projects to suffer from burnout, especially when needing to triage a large number of incoming issues instead of actually building things. Here are some of the steps we take to try mitigate this:

- If the problem can not be reproduced in the [demo of xterm.js](https://github.com/xtermjs/xterm.js/wiki/Contributing#running-the-demo), please provide an HTML document that demonstrates the problem.
-
- Be polite. Issues with an indignant or belligerent tone tend to be moved to the
-  bottom of the pile.
+- Support questions live in [GH discussions](https://github.com/xtermjs/xterm.js/discussions), issues may be transfered there without further comment and core maintainers may or may not participate in discussions.
+- Issues are strictly for well defined features or bugs that are _actionable_.
+- Sometimes features are out of scope. A common example of this is a niche feature that the pricipal implementation ([VS Code](https://code.visualstudio.com/)) won't leverage and therefore would be difficult to maintain and likely suffer from bitrot. The reporter may not agree with this, but you could always create an addon if that works or maintain your own fork if it comes to that.
+- If a feature does not have a clear way forward or needs more discussion it may be closed ro moved to a discussion.
+- If a bug is not easily reproducible it may be closed or moved to a discussion. Generally issues that are labeled are something we want to do or has actionable steps to look into further.

 ## Answering discussion questions

-Issues are only meant to track (likely) feature requests and bugs. We use [GitHub Discussions](https://github.com/xtermjs/xterm.js/discussions) for general Q&A as well as discussing possible features. If you want to help out, many questions get asked over at the [discussions page](https://github.com/xtermjs/xterm.js/discussions) which could use an expert as the core team is often stretched thin.

 ### Addons

 Addons are separate modules that extend the `Terminal` by building on the [xterm.js API](https://github.com/xtermjs/xterm.js/blob/master/typings/xterm.d.ts). To use an addon, you first need to install it in your project:

 ```bash
-npm i -S xterm-addon-web-links
+npm install --save @xterm/addon-web-links

 ## API

 The full API for xterm.js is contained within the [TypeScript declaration file](https://github.com/xtermjs/xterm.js/blob/master/typings/xterm.d.ts), use the branch/tag picker in GitHub (`w`) to navigate to the correct version of the API.

-Note that some APIs are marked *experimental*, these are added to enable experimentation with new ideas without committing to support it like a normal [semver](https://semver.org/) API. Note that these APIs can change radically between versions, so be sure to read release notes if you plan on using experimental APIs.
