Spec-Implement

Execute implementation plan by processing tasks.md.

Prerequisites: tasks.md must exist (run /spec-tasks first).

Workflow

1. Initialize - Run .specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks
2. Check checklists - Verify all checklists complete (if any)
3. Load context - tasks.md, plan.md, data-model.md, contracts/
4. Setup verification - Create/verify ignore files
5. Parse tasks - Extract phases, dependencies, parallel markers
6. Execute - Phase-by-phase implementation
7. Track progress - Mark completed tasks [X]
8. Validate - Verify completion and test results

Checklist Gate

If FEATURE_DIR/checklists/ exists:

| Checklist | Total | Completed | Incomplete | Status |
|-----------|-------|-----------|------------|--------|
| ux.md     | 12    | 12        | 0          | ✓ PASS |
| test.md   | 8     | 5         | 3          | ✗ FAIL |

• All PASS → Proceed automatically
• Any FAIL → Ask user confirmation

Ignore Files Setup

Detect and create based on tech stack:

Detection	Create
.git exists	.gitignore
Dockerfile*	.dockerignore
.eslintrc*	.eslintignore
package.json	.npmignore
*.tf files	.terraformignore

Execution Rules

Phase Order

1. Setup - Project initialization
2. Tests - Write failing tests (if TDD)
3. Core - Models, services, CLI
4. Integration - DB, middleware, external services
5. Polish - Optimization, documentation

Dependency Rules

• Sequential tasks → In order
• [P] tasks → Can run together
• Same file → Sequential
• Phase complete → Next phase

Progress Tracking

• Report after each task
• Halt on non-parallel failure
• Mark completed: - [X] T001...

Technology Patterns

Node.js/TypeScript

node_modules/, dist/, build/, *.log, .env*

Python

__pycache__/, *.pyc, .venv/, dist/, *.egg-info/

Go

*.exe, *.test, vendor/, *.out

Rust

target/, debug/, release/, *.rs.bk

Completion Validation

• All required tasks completed
• Implementation matches specification
• Tests pass (if applicable)
• Coverage meets requirements

Next Steps

After /spec-implement:

• Run tests and verify
• Create PR or deploy
