# Project Planning & Task Breakdown

## Milestones
**What are the major checkpoints?**

- [ ] Milestone 1: Requirements/design approved and migration strategy locked
- [ ] Milestone 2: Core wizard + plan/apply execution implemented
- [ ] Milestone 3: Tool adapters, tests, docs, and rollout guidance complete

## Task Breakdown
**What specific work needs to be done?**

### Phase 1: Foundation
- [ ] Task 1.1: Audit current `setup --global` behavior and codify compatibility requirements
- [ ] Task 1.2: Define `ToolAdapter`, `SetupPlan`, `SetupState`, and `SetupReport` types
- [ ] Task 1.3: Implement environment detection and capability resolution
- [ ] Task 1.4: Define setup profiles (`quickstart`, `team-default`, `custom`)
- [ ] Task 1.5: Add state repository and fingerprint utilities

### Phase 2: Core Features
- [ ] Task 2.1: Build interactive wizard flow for profile/tool/asset selection
- [ ] Task 2.2: Implement dry-run plan preview with clear operation listing
- [ ] Task 2.3: Implement setup executor with backup and overwrite policies
- [ ] Task 2.4: Implement non-interactive mode flags and validation
- [ ] Task 2.5: Add summary/report output (human + optional json)

### Phase 3: Integration & Polish
- [ ] Task 3.1: Migrate existing `setup --global` entry to new wizard architecture
- [ ] Task 3.2: Add adapter support for Codex, Claude Code, and Antigravity
- [ ] Task 3.3: Implement conflict UX for existing customized files
- [ ] Task 3.4: Add `--doctor` diagnostics mode (recommended extension)
- [ ] Task 3.5: Update CLI help, README, and migration notes

### Phase 4: Validation
- [ ] Task 4.1: Unit tests for planner, executor, and adapter mappings
- [ ] Task 4.2: Integration tests for interactive and non-interactive flows
- [ ] Task 4.3: Manual matrix test across macOS/Linux/Windows path behaviors
- [ ] Task 4.4: Benchmark cold and warm run timing against targets

## Dependencies
**What needs to happen in what order?**

- Task dependencies and blockers
  - Data model definitions (Phase 1) must land before planner/executor implementation (Phase 2).
  - Adapter contracts must be stable before writing integration tests.
  - Migration strategy should be confirmed before changing default command behavior.
- External dependencies (APIs, services, etc.)
  - None required for v1 local setup path.
  - Optional online recommendation sync should remain behind a feature flag.
- Team/resource dependencies
  - CLI maintainer for architecture changes.
  - Reviewer with cross-platform path and file-permission expertise.

## Timeline & Estimates
**When will things be done?**

- Estimated effort per task/phase
  - Phase 1: 1.5-2 days
  - Phase 2: 2-3 days
  - Phase 3: 1.5-2 days
  - Phase 4: 1-1.5 days
- Target dates for milestones
  - Milestone 1: end of week 1
  - Milestone 2: mid week 2
  - Milestone 3: end of week 2
- Buffer for unknowns
  - +20% for tool path variance, overwrite edge cases, and migration surprises

## Risks & Mitigation
**What could go wrong?**

- Technical risks
  - Incorrect path assumptions per tool may cause invalid writes.
  - Migration from `--global` behavior could break existing scripts.
- Resource risks
  - Cross-platform validation may be under-tested if limited test machines.
- Dependency risks
  - Tool ecosystem changes can invalidate adapter mappings.
- Mitigation strategies
  - Add adapter contract tests and fixture-based path validation.
  - Preserve compatibility alias for `setup --global` during transition.
  - Add explicit preview + confirmation to prevent accidental writes.
  - Keep a fast rollback path: feature flag to restore legacy behavior temporarily.

## Resources Needed
**What do we need to succeed?**

- Team members and roles
  - CLI implementer, reviewer, and docs owner
- Tools and services
  - Existing TypeScript test framework and CI workflow
- Infrastructure
  - Cross-platform CI runners or local validation checklists
- Documentation/knowledge
  - Canonical tool path/capability matrix for supported environments
