File contents

Spec-Implement

Execute implementation plan by processing tasks.md.

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

Workflow

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

Setup - Project initialization
Tests - Write failing tests (if TDD)
Core - Models, services, CLI
Integration - DB, middleware, external services
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
