-# Codebuff CLI Staging
+# 🚀 Codecane - The most powerful coding agent (STAGING)
 
-The staging workflow updates these files with the exact version being packaged. They are shipped as workflow artifacts so downstream jobs build and publish binaries from the same commit snapshot.
+**⚠️ This is a staging/beta release for testing purposes.**
+
+Codecane is a CLI tool that writes code for you.
+
+1. Run `codecane` from your project directory
+2. Tell it what to do
+3. It will read and write to files and run commands to produce the code you want
+
+Note: Codecane will run commands in your terminal as it deems necessary to fulfill your request.
+
+## Installation
+
+To install Codecane (staging), run:
+
+```bash
+npm install -g codecane@beta
+```
+
+(Use `sudo` if you get a permission error.)
+
+## Usage
+
+After installation, you can start Codecane by running:
+
+```bash
+codecane [project-directory]
+```
+
+If no project directory is specified, Codecane will use the current directory.
+
+Once running, simply chat with Codecane to say what coding task you want done.
+
+## Features
+
+- Understands your whole codebase
+- Creates and edits multiple files based on your request
+- Can run your tests or type checker or linter; can install packages
+- It's powerful: ask Codecane to keep working until it reaches a condition and it will.
+
+Our users regularly use Codecane to implement new features, write unit tests, refactor code, write scripts, or give advice.
+
+## Knowledge Files
+
+To unlock the full benefits of modern LLMs, we recommend storing knowledge alongside your code. Add a `knowledge.md` file anywhere in your project to provide helpful context, guidance, and tips for the LLM as it performs tasks for you.
+
+Codecane can fluently read and write files, so it will add knowledge as it goes. You don't need to write knowledge manually!
+
+Some have said every change should be paired with a unit test. In 2024, every change should come with a knowledge update!
+
+## Tips
+
+1. Type '/help' or just '/' to see available commands.
+2. Create a `knowledge.md` file and collect specific points of advice. The assistant will use this knowledge to improve its responses.
+3. Type `undo` or `redo` to revert or reapply file changes from the conversation.
+4. Press `Esc` or `Ctrl+C` while Codecane is generating a response to stop it.
+
+## Troubleshooting
+
+If you are getting permission errors during installation, try using sudo:
+
+```
+sudo npm install -g codecane@beta
+```
+
+If you still have errors, it's a good idea to [reinstall Node](https://nodejs.org/en/download).
+
+## Feedback
+
+We value your input! Please email your feedback to `founders@codebuff.com`. Thank you for using Codecane!

Subject: [PATCH 24/44] feat(cli): add --agent flag for agent selection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds Commander.js-based CLI argument parsing with --agent flag to allow users to specify which agent to use when starting the CLI. The agent ID is threaded through the App component to the SDK's client.run() call.

Changes:
- Add commander package for robust CLI argument parsing
- Add --agent flag to specify agent ID (e.g., 'ask', 'base-lite', or full IDs like 'codebuff/base-lite@1.0.0')
- Thread agentId through App component and useSendMessage hook to SDK
- Add comprehensive unit tests for CLI argument parsing
- Add testing documentation in cli/src/__tests__/README.md
- Preserve existing --clear-logs, --help, and --version flags

+# CLI Testing Guide
+
+## Unit Tests
+
+Run unit tests for CLI argument parsing:
+
+```bash
+cd cli
+bun test src/__tests__/cli-args.test.ts
+```
+
+These tests verify:
+- `--agent` flag parsing with various agent IDs
+- `--clear-logs` flag functionality
+- Multi-flag combinations
+- Help and version flags
+- Edge cases (empty args, multi-word prompts)
+
+## Non-Interactive Testing
+
+### Manual Testing
+
+Test the `--agent` flag manually:
+
+```bash
+# Test with a specific agent
+cd cli
+bun run src/index.tsx --agent ask "what is this project about?"
+
+# Test with full agent ID
+bun run src/index.tsx --agent codebuff/base-lite@1.0.0 "hello"
+
+# Test without agent flag (uses default 'base')
+bun run src/index.tsx "create a new component"
+
+# Test help output
+bun run src/index.tsx --help
+
+# Test version output
+bun run src/index.tsx --version
+```
+
+### Automated Testing
+
+For CI/CD pipelines, run the unit tests:
+
+```bash
+cd cli
+bun test
+```
+
+## Test Coverage
+
+The tests ensure:
+
+1. **Flag Parsing**: All flags are correctly parsed and passed through
+2. **Agent Selection**: The `--agent` flag value is passed to the SDK's `client.run()` call
+3. **Backward Compatibility**: Existing functionality without flags continues to work
+4. **Error Handling**: Invalid flags are caught by Commander.js
+
+## Continuous Testing
+
+Add to your CI pipeline:
+
+```yaml
+- name: Test CLI flags
+  run: |
+    cd cli
+    bun test
+```
+
+## Future Enhancements
+
+To add more flags:
+
+1. Add the option in `cli/src/index.tsx` using `.option()`
+2. Pass it through to the App component
+3. Thread it to the SDK call in `useSendMessage`
+4. Add tests in `cli/src/__tests__/cli-args.test.ts`

 # CLI Package Knowledge
 
+## Test Naming Conventions
+
+**IMPORTANT**: Follow these naming patterns for automatic dependency detection:
+
+- **Unit tests:** `*.test.ts` (e.g., `cli-args.test.ts`)
+- **E2E tests:** `e2e-*.test.ts` (e.g., `e2e-cli.test.ts`)
+- **Integration tests:** `integration-*.test.ts` (e.g., `integration-tmux.test.ts`)
+
+**Why?** The `.bin/bun` wrapper detects files matching `*integration*.test.ts` or `*e2e*.test.ts` patterns and automatically checks for tmux availability. If tmux is missing, it shows installation instructions but lets tests continue (they skip gracefully).
+
+**Benefits:**
+
+- Project-wide convention (not CLI-specific)
+- No hardcoded directory paths
+- Automatic dependency validation
+- Clear test categorization
+
 ## Migration from Custom OpenTUI Fork
 
 **October 2024**: Migrated from custom `CodebuffAI/opentui#codebuff/custom` fork to official `@opentui/react@^0.1.27` and `@opentui/core@^0.1.27` packages.

-# Test with a specific agent
-cd cli
-bun run src/index.tsx --agent ask "what is this project about?"
+# macOS
+brew install tmux
+
+# Ubuntu/Debian
+sudo apt-get install tmux
 
-# Test with full agent ID
-bun run src/index.tsx --agent codebuff/base-lite@1.0.0 "hello"
+# Windows (via WSL)
+wsl --install
+sudo apt-get install tmux
+```
 
-# Test without agent flag (uses default 'base')
-bun run src/index.tsx "create a new component"
+### For E2E Tests
 
-# Test help output
-bun run src/index.tsx --help
+Build the SDK first:
 
-# Test version output
-bun run src/index.tsx --version
+```bash
+cd sdk
+bun run build
+cd ../cli
 ```
 
-### Automated Testing
+## Running Tests
 
-For CI/CD pipelines, run the unit tests:
+### All Tests
 
 ```bash
-cd cli
 bun test
 ```
 
-## Test Coverage
+### Specific Test Suites
 
-The tests ensure:
+```bash
+# Unit tests
+bun test cli-args.test.ts
 
-1. **Flag Parsing**: All flags are correctly parsed and passed through
-2. **Agent Selection**: The `--agent` flag value is passed to the SDK's `client.run()` call
-3. **Backward Compatibility**: Existing functionality without flags continues to work
-4. **Error Handling**: Invalid flags are caught by Commander.js
+# E2E tests (requires SDK)
+bun test e2e-cli.test.ts
 
-## Continuous Testing
+# Integration tests (requires tmux)
+bun test integration-tmux.test.ts
+```
 
-Add to your CI pipeline:
+### Manual tmux POC
 
-```yaml
-- name: Test CLI flags
-  run: |
-    cd cli
-    bun test
+```bash
+bun run test:tmux-poc
 ```
 
-## Future Enhancements
+## Automatic tmux Detection
+
+The `.bin/bun` wrapper automatically checks for tmux when running integration/E2E tests:
+
+- **Detects** test files matching `*integration*.test.ts` or `*e2e*.test.ts`
+- **Checks** if tmux is installed
+- **Shows** installation instructions if missing
+- **Skips** tests gracefully if tmux unavailable
+
+**Benefits:**
+- ✅ Project-wide (works in any package)
+- ✅ No hardcoded paths
+- ✅ Clear test categorization
+- ✅ Automatic dependency validation
+
+## Test Structure
+
+### Unit Tests
+
+Test individual functions in isolation:
+
+```typescript
+import { describe, test, expect } from 'bun:test'
+
+describe('CLI Arguments', () => {
+  test('parses --agent flag', () => {
+    // Test implementation
+  })
+})
+```
+
+### Integration Tests (tmux)
+
+Test interactive CLI with full terminal emulation:
+
+```typescript
+import { describe, test, expect } from 'bun:test'
+import { isTmuxAvailable } from './test-utils'
+
+const tmuxAvailable = isTmuxAvailable()
+
+describe.skipIf(!tmuxAvailable)('CLI Integration Tests', () => {
+  test('handles user input', async () => {
+    // Create tmux session
+    // Send commands
+    // Verify output
+  })
+})
+```
+
+### E2E Tests
+
+Test complete CLI workflows:
+
+```typescript
+import { describe, test, expect } from 'bun:test'
+import { isSDKBuilt } from './test-utils'
+
+const sdkBuilt = isSDKBuilt()
+
+describe.skipIf(!sdkBuilt)('CLI E2E Tests', () => {
+  test('runs --help command', async () => {
+    // Test CLI behavior
+  })
+})
+```
+
+## Test Utilities
+
+Shared utilities in `test-utils.ts`:
+
+```typescript
+import { isTmuxAvailable, isSDKBuilt, sleep } from './test-utils'
+
+// Check for tmux
+if (isTmuxAvailable()) {
+  // Run tmux tests
+}
+
+// Check for SDK
+if (isSDKBuilt()) {
+  // Run E2E tests
+}
+
+// Async delay
+await sleep(1000)
+```
+
+## tmux Testing Approach
+
+### Why tmux?
+
+- ✅ Full terminal emulation with PTY support
+- ✅ No native compilation needed (Bun 1.3+ compatible)
+- ✅ Send keystrokes, capture output
+- ✅ Can attach to sessions for debugging
+- ✅ Cross-platform (macOS, Linux, WSL)
 
-To add more flags:
+### Basic tmux Workflow
 
-1. Add the option in `cli/src/index.tsx` using `.option()`
-2. Pass it through to the App component
-3. Thread it to the SDK call in `useSendMessage`
-4. Add tests in `cli/src/__tests__/cli-args.test.ts`
+```typescript
+// 1. Create tmux session
+await tmux(['new-session', '-d', '-s', sessionName, 'your-command'])
+
+// 2. Send commands
+await tmux(['send-keys', '-t', sessionName, 'input text', 'Enter'])
+
+// 3. Wait for output
+await sleep(1000)
+
+// 4. Capture output
+const output = await tmux(['capture-pane', '-t', sessionName, '-p'])
+
+// 5. Clean up
+await tmux(['kill-session', '-t', sessionName])
+```
+
+### tmux Helper Function
+
+```typescript
+function tmux(args: string[]): Promise<string> {
+  return new Promise((resolve, reject) => {
+    const proc = spawn('tmux', args, { stdio: 'pipe' })
+    let stdout = ''
+    
+    proc.stdout?.on('data', (data) => {
+      stdout += data.toString()
+    })
+    
+    proc.on('close', (code) => {
+      code === 0 ? resolve(stdout) : reject(new Error('tmux failed'))
+    })
+  })
+}
+```
+
+## Debugging Tests
+
+### Attach to tmux Session
+
+For debugging, keep session alive and attach:
+
+```typescript
+// Don't kill session immediately
+await tmux(['new-session', '-d', '-s', 'debug-session', 'cli-command'])
+
+// In another terminal
+// tmux attach -t debug-session
+```
+
+### View Test Output
+
+```bash
+# Verbose test output
+bun test --verbose
+
+# Watch mode
+bun test --watch
+```
+
+## Contributing
+
+When adding new tests:
+
+1. **Follow naming convention** (`*integration*.test.ts` or `*e2e*.test.ts`)
+2. **Use test-utils.ts** for shared functionality
+3. **Add graceful skipping** for missing dependencies
+4. **Clean up resources** (tmux sessions, temp files)
+5. **Document test purpose** clearly in test descriptions
+
+## Troubleshooting
+
+### tmux Not Found
+
+```
+⚠️  tmux not found but required for integration/E2E tests
+```
+
+**Solution:** Install tmux (see Prerequisites above)
+
+### SDK Not Built
+
+```
+✓ Build SDK for E2E tests: cd sdk && bun run build [skip]
+```
+
+**Solution:** Build the SDK first (see Prerequisites above)
+
+### Tests Hanging
+
+- Check tmux session isn't waiting for input
+- Ensure proper cleanup in `finally` blocks
+- Use timeouts for tmux operations
+
+### Session Already Exists
+
+- Use unique session names (e.g., timestamp suffix)
+- Clean up sessions in `beforeEach`/`afterEach`
+
+## Performance
+
+- **Unit tests:** ~100ms total
+- **Integration tests:** ~2-5s per test (tmux overhead)
+- **E2E tests:** ~3-10s per test (full CLI startup)
+
+## CI/CD
+
+For CI environments:
+
+```yaml
+# Install tmux in CI
+- name: Install tmux
+  run: |
+    sudo apt-get update
+    sudo apt-get install -y tmux
+
+# Run tests
+- name: Run tests
+  run: bun test
+```

-# GitHub Actions Knowledge
+# GitHub Workflows
+
+## Refactoring Patterns
+
+### Composite Actions
+
+Common setup steps (checkout, Bun setup, caching, installation) have been extracted to `.github/actions/setup-project/action.yml`.
+
+Usage:
+
+```yaml
+steps:
+  - uses: actions/checkout@v4
+    with:
+      # checkout-specific params
+
+  - uses: ./.github/actions/setup-project
+```
+
+Note: Checkout must be separate from the composite action to avoid circular dependencies.
+
+### Environment Variables
+
+GitHub API URLs are extracted as environment variables to avoid duplication:
+
+```yaml
+env:
+  GITHUB_API_URL: https://api.github.com/repos/CodebuffAI/codebuff
+  GITHUB_UPLOADS_URL: https://uploads.github.com/repos/CodebuffAI/codebuff
+```
+
+This pattern:
+
+- Reduces duplication across workflow steps
+- Makes repository changes easier (single point of change)
+- Improves readability and maintainability

Subject: [PATCH 38/44] feat: use dts-bundle-generator for SDK type generation
 in typecheck

Changes:
- SDK build:types now uses dts-bundle-generator to create bundled types
- Added pretypecheck hooks to npm-app and evals packages
- This ensures SDK types are properly bundled at dist/index.d.ts

Benefits:
- Single bundled type file instead of nested structure
- Works correctly with SDK's package.json types field
- Packages can resolve @codebuff/sdk types during typecheck

Subject: [PATCH 39/44] fix: improve ripgrep binary path resolution for bundled
 SDK
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the SDK is bundled and called from other packages during tests, the
ripgrep binary path resolution was failing because:
1. Caller's import.meta.url was passed to getBundledRgPath()
2. SDK tried to resolve vendor/ relative to the caller's location
3. This failed in workspace monorepo setups

Changes:
- SDK now uses its own import.meta.url as fallback when none provided
- Added distPath check for bundled SDK (dist/index.mjs → dist/vendor/)
- npm-app now calls getBundledRgPath() without passing import.meta.url
- Added pretest hook to build SDK before running npm-app tests

Fixes npm-app test failures where ripgrep binary couldn't be found.

Subject: [PATCH 40/44] fix: update completions test to use run_id instead of
 agent_run_id
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The API endpoint changed from agent_run_id to run_id in origin/main.
Updated test expectations to match the new parameter names and error messages.

Changes:
- Updated request bodies: agent_run_id → run_id
- Updated error messages: agentRunId → runId
- Updated mock function parameter: agentRunId → runId

Subject: [PATCH 41/44] fix: update tests to match API changes from origin/main
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Test fixes to match updated API contracts and property names:

- code-map: queryText → queryPathOrContent
- billing: Updated mock implementations for async module loading
- openrouter-ai-sdk: Fixed streaming test mocks for ReadableStream handling

These test updates were previously in commit 119218a but were reverted.
Re-applying only the test fixes without other changes from that commit.

Subject: [PATCH 42/44] chore: remove Playwright e2e test incompatible with bun
 test

The Playwright test was causing errors when running bun test at the root level
since Playwright tests need to be run separately with playwright test command.

Subject: [PATCH 43/44] fix: use --cwd=<dir> syntax for bun run commands

The --cwd flag requires '=' syntax when used with 'bun run' in bun 1.3.0.
Without it, bun displays help menu instead of executing the command, causing
SDK type generation to be skipped during CI typecheck.

Subject: [PATCH 44/44] fix: build SDK before running tests in CI

The test jobs run individual test files with 'bun test <file>', which bypasses
the package.json pretest hook. This caused npm-app tests to fail with 'Cannot
find module @codebuff/sdk' because the SDK wasn't built.

Changes:
- Added 'Build SDK before tests' step in test job
- Added 'Build SDK before integration tests' step in test-integration job
- This ensures SDK dist artifacts (index.mjs, index.cjs, vendor/) exist
  before tests that depend on @codebuff/sdk are executed

Root cause: CI test command bypasses npm hooks by running test files directly.
