Summary

• What changed: Added a new /auto-improve slash command that lets Qwen Code run a session-scoped loop for small, locally verifiable repository improvements. The command supports source configuration, loop start/status/stop controls, scheduled ticks, and local state tracking for each run.
• Source configuration: /auto-improve source supports built-in source toggles plus an editable custom source list. Users can add multiple custom source hints, edit existing hints, delete hints, and save them into the repository-level auto-improve config.
• Delivery policy: Auto-improve now uses source-aware local delivery. Local/default tasks target the loop's default branch, PR-derived tasks target the PR head branch, unclear targets use a local-only branch, and push is skipped unless the user explicitly requested it.
• Cancellation behavior: Cancelling an auto-improve tick with Escape marks the active run as cancelled when possible and reminds the user that the loop remains active until /auto-improve stop.
• Why it changed: To provide a structured automated improvement workflow where the agent can analyze, plan, implement, verify, and locally commit changes from isolated worktrees without accidentally delivering PR fixes to the wrong branch.
• Reviewer focus: Verify the command naming and help text, scheduled tick behavior, state management during improvement sessions, worktree isolation model, custom source list UX, legacy single-context config migration, source-aware delivery rules, and PR source prioritization for open non-draft PRs with actionable unresolved review feedback.

Validation

• Commands run:

  npm run build
  npm run typecheck
  cd packages/cli && npx vitest run src/ui/commands/autoImproveCommand.test.ts

• Expected result: /auto-improve source opens source configuration, supports adding/editing/deleting custom source entries, and /auto-improve start --every <interval> [prompt] snapshots those custom sources into the loop and schedules /auto-improve tick <loop-id>. Tick instructions require PR-derived tasks to use PR head branches and prohibit push unless explicitly requested.
• Observed result: Build passes; typecheck passes; the focused command test passes with 8 tests.
• Quickest reviewer verification path: Run the focused test above, then try /auto-improve source and /auto-improve start --every 30m in the CLI with cron enabled.

Scope / Risk

• Main risk or tradeoff: Worktree cleanup on failure or interrupt; a hard process kill could still leave orphaned local worktrees.
• Not covered / not validated: Cross-platform worktree behavior, especially Windows.
• Breaking changes / migration notes: This PR introduces the command as /auto-improve. Existing draft userContext config is migrated into the new custom source list on read.

Testing Matrix

Testing matrix notes:

• Core logic and focused tests were validated on macOS.
• Windows worktree behavior needs separate validation.
