+# Contributing to pi-browser-harness
+
+Thanks for your interest in improving `pi-browser-harness`. This project gives pi agents full browser control through the Chrome DevTools Protocol (CDP): navigation, screenshots, clicks, typing, JavaScript evaluation, tab management, and runtime helper scripts.
+
+---
+
+## Setup
+
+### 1. Fork and clone
+
+```bash
+git clone https://github.com/YOUR_USERNAME/pi-browser-harness.git
+cd pi-browser-harness
+```
+
+If you are working directly from the upstream repository:
+
+```bash
+git clone https://github.com/amankumarsingh77/pi-browser-harness.git
+cd pi-browser-harness
+```
+
+### 2. Install dependencies
+
+```bash
+npm install
+```
+
+### 3. Run the local checks
+
+```bash
+npm run typecheck
+npm pack --dry-run
+```
+
+`npm run typecheck` validates the TypeScript source. `npm pack --dry-run` verifies that the package can be packed for publishing and shows which files will be included.
+

+```
+
+---
+
+## Developing locally
+
+Make changes in `src/`, then run:
+
+```bash
+npm run typecheck
+```
+
+To test the extension in pi from your local checkout, install it by path:
+
+```bash
+pi install /absolute/path/to/pi-browser-harness
+```
+
+For example:
+
+```bash
+pi install "$PWD"
+```
+
+Then start pi and run:
+
+```text
+/browser-setup
+/browser-status
+```
+
+Use the normal browser workflow when testing: screenshot → act → screenshot → verify. For example, navigate to a page, wait for load, capture a screenshot, and confirm the result visually.
+
+---
+
+## Code conventions
+
+- Write TypeScript and keep the project passing `npm run typecheck`.
+- Keep `strict` TypeScript mode clean. Do not introduce implicit `any` values.
+- Prefer small, focused changes over broad rewrites.
+- Keep tool descriptions, parameter descriptions, and prompt guidelines clear and user-facing.
+- Preserve the existing error-handling style: return useful, actionable messages to the agent instead of leaking low-level details when possible.
+- Avoid adding dependencies unless they are necessary for the browser-control experience.
+- Keep README and CHANGELOG updates in the same PR when behavior changes.
+
+---
+
+## Adding a new browser tool
+
+Most browser tools are registered in `src/tools.ts` through `pi.registerTool`.
+
+When adding a tool:
+
+1. Add or reuse the underlying daemon method in `src/daemon.ts` and protocol types in `src/protocol.ts` when needed.
+2. Register the pi tool in `src/tools.ts` with:
+   - a stable `browser_*` name,
+   - a concise label and description,
+   - a TypeBox parameter schema,
+   - prompt snippets and guidelines that explain when to use it,
+   - clear result text and structured details where useful.
+3. Update prompt guidance in `src/prompt.ts` if the tool changes recommended workflows.
+4. Add or update a renderer in `src/renderers.ts` if the tool returns visual or rich output.
+5. Document the tool in `README.md` and note the change in `CHANGELOG.md`.
+6. Run:
+
+   ```bash
+   npm run typecheck
+   npm pack --dry-run
+   ```
+
+Keep tool behavior predictable. The agent should be able to verify actions with screenshots or page state after every interaction.
+
+---
+
+## Pull request process
+
+1. Fork the repository.
+2. Create a focused branch:
+
+   ```bash
+   git checkout -b fix/short-description
+   ```
+
+3. Make your changes and keep commits readable.
+4. Run local checks:
+
+   ```bash
+   npm run typecheck
+   npm pack --dry-run
+   ```
+
+5. Test in pi with a local path install when the change affects runtime behavior.
+6. Update documentation and CHANGELOG entries when user-visible behavior changes.
+7. Open a pull request against `main` and describe what changed, how it was tested, and any follow-up work.
+
+Thank you for helping make browser automation in pi reliable, inspectable, and easy to use.
