-# Story 128: Add test coverage for worktree.rs
-
-Currently at 65% line coverage (330 lines, 124 missed). Worktree management is core infrastructure — creating, removing, and managing git worktrees for agent isolation.
-
-## What to test
-
-- `worktree_path` construction
-- `create_worktree` — branch naming, git worktree add, setup command execution
-- `remove_worktree_by_story_id` — cleanup, branch deletion
-- Setup command runner (pnpm install, pnpm build, cargo check)
-- Error paths: git failures, setup failures, missing directories
-- Edge cases: worktree already exists, branch already exists
-
-## Notes
-
-- Use temp git repos for integration tests
-- Mock expensive operations (pnpm install, cargo check) where possible
-- The setup command failure path is especially important (this was the root cause of bug 118)
-
-## Acceptance Criteria
-
-- [ ] Line coverage for `worktree.rs` reaches 80%+
-- [ ] Tests pass with `cargo test`
-- [ ] `cargo clippy` clean
