pi-worktrees/README.md
David Kong 2e4ef7035a docs: address code review findings for issue-1
- Split Validation Checklist into verifiable docs vs deferred implementation checks (AGENTS.md)
- Correct README example output to match actual `git worktree list` format
- Add pi platform version requirement (`pi >= 0.5.0`) to Requirements section
- Add Testing Strategy section with unit, integration, and manual verification procedures (DESIGN.md)
- Document annotated `git worktree list` raw output format with parsing rules (DOMAIN.md)
- Add permission fail condition for `create` tool in Tool Behaviors table

# pi-worktree
A pi extension for managing git worktrees through intuitive tool commands and an interactive picker.
## Tools
### `git_worktree_create`
Create a linked worktree for a branch in the current repo.
```typescript
{
path: string, // Path for the new worktree
branch?: string, // Branch name (new or existing). Defaults to 'main'.
create_branch?: boolean // Create a new branch? Defaults to true if branch doesn't exist.
}
```
**Example**: `git_worktree_create({ path: "./feature-x", branch: "feature-x" })`
### `git_worktree_list`
List all linked worktrees in the current repo.
```typescript
// No parameters required
```
Returns structured data with `branch`, `path`, and `isCurrent` for each worktree.
**Example output** (raw `git worktree list` format, parsed into structured data):
```
/home/user/repo abc1234 [main]
/home/user/repo/feature-x def5678 [feature-x]
```
### `git_worktree_switch`
Switch pi's working directory to a linked worktree.
```typescript
{
target: string // Path or branch name of the target worktree
}
```
**Example**: `git_worktree_switch({ target: "./feature-x" })`
After switching, you'll be offered the option to create a new session for that worktree context.
### `git_worktree_remove`
Remove a linked worktree.
```typescript
{
path: string // Path of the worktree to remove
}
```
**Example**: `git_worktree_remove({ path: "./feature-x" })`
## Command
### `/worktree`
Interactive picker to switch between linked worktrees.
Lists all worktrees with a branch-first display and lets you select one to switch to. Automatically updates pi's branch display after switching.
## Behavior
- **Fail fast**: Refuses dangerous operations (existing paths, current branch, uncommitted changes) with clear messages and suggested fixes.
- **Stateless tools**: Each call works independently based on current git state.
- **Session integration**: Branch display updates automatically; you're offered a new session after switching worktrees.
- **Back-switching**: When returning to the main repo, pi restores the previous session.
## Requirements
- **pi >= 0.5.0** (with `ExtensionAPI` and `registerCommand` support)
- Git 2.x with worktree support (all modern versions)
- No external npm dependencies — uses only pi's extension API and TypeBox schemas.
