speckit.implement
The speckit.implement command executes a structured implementation workflow by first verifying project prerequisites and checklist completion status, then loading implementation context from specification documents (tasks.md, plan.md, and optional supporting files), and finally setting up or verifying project configuration files. Use this command when ready to begin or resume development work on a defined project feature after specifications have been documented.

## User Input

$ARGUMENTS
```
You **MUST** consider the user input before proceeding (if not empty).
## Outline
1. Run `.specify/scripts/bash/check-prerequisites.sh --json --require-tasks --include-tasks` from repo root and parse FEATURE_DIR and AVAILABLE_DOCS list. All paths must be absolute. For single quotes in args like "I'm Groot", use escape syntax: e.g 'I'\''m Groot' (or double-quote if possible: "I'm Groot").
2. **Check checklists status** (if FEATURE_DIR/checklists/ exists):
- Scan all checklist files in the checklists/ directory
- For each checklist, count:
- Total items: All lines matching `- [ ]` or `- [X]` or `- [x]`
- Completed items: Lines matching `- [X]` or `- [x]`
- Incomplete items: Lines matching `- [ ]`
- Create a status table:
```text
| Checklist | Total | Completed | Incomplete | Status |
|-----------|-------|-----------|------------|--------|
| ux.md | 12 | 12 | 0 | ✓ PASS |
| test.md | 8 | 5 | 3 | ✗ FAIL |
| security.md | 6 | 6 | 0 | ✓ PASS |
```
- Calculate overall status:
- **PASS**: All checklists have 0 incomplete items
- **FAIL**: One or more checklists have incomplete items
- **If any checklist is incomplete**:
- Display the table with incomplete item counts
- **STOP** and ask: "Some checklists are incomplete. Do you want to proceed with implementation anyway? (yes/no)"
- Wait for user response before continuing
- If user says "no" or "wait" or "stop", halt execution
- If user says "yes" or "proceed" or "continue", proceed to step 3
- **If all checklists are complete**:
- Display the table showing all checklists passed
- Automatically proceed to step 3
3. Load and analyze the implementation context:
- **REQUIRED**: Read tasks.md for the complete task list and execution plan
- **REQUIRED**: Read plan.md for tech stack, architecture, and file structure
- **IF EXISTS**: Read data-model.md for entities and relationships
- **IF EXISTS**: Read contracts/ for API specifications and test requirements
- **IF EXISTS**: Read research.md for technical decisions and constraints
- **IF EXISTS**: Read quickstart.md for integration scenarios
4. **Project Setup Verification**:
- **REQUIRED**: Create/verify ignore files based on actual project setup:
**Detection & Creation Logic**:
- Check if the following command succeeds to determine if the repository is a git repo (create/verify .gitignore if so):
```sh
git rev-parse --git-dir 2>/dev/null
```
- Check if Dockerfile* exists or Docker in plan.md → create/verify .dockerignore
- Check if .eslintrc* exists → create/verify .eslintignore
- Check if eslint.config.* exists → ensure the config's `ignores` entries cover required patterns
- Check if .prettierrc* exists → create/verify .prettierignore
- Check if .npmrc or package.json exists → create/verify .npmignore (if publishing)
- Check if terraform files (*.tf) exist → create/verify .terraformignore
- Check if .helmignore needed (helm charts present) → create/verify .helmignore
**If ignore file already exists**: Verify it contains essential patterns, append missing critical patterns only
**If ignore file missing**: Create with full pattern set for detected technology
**Common Patterns by Technology** (from plan.md tech stack):
- **Node.js/JavaScript/TypeScript**: `node_modules/`, `dist/`, `build/`, `*.log`, `.env*`

5. Parse tasks.md structure and extract:
- **Task phases**: Setup, Tests, Core, Integration, Polish
- **Task dependencies**: Sequential vs parallel execution rules
- **Task details**: ID, description, file paths, parallel markers [P]
- **Execution flow**: Order and dependency requirements
6. Execute implementation following the task plan:
- **Phase-by-phase execution**: Complete each phase before moving to the next
- **Respect dependencies**: Run sequential tasks in order, parallel tasks [P] can run together
- **Follow TDD approach**: Execute test tasks before their corresponding implementation tasks
- **File-based coordination**: Tasks affecting the same files must run sequentially
- **Validation checkpoints**: Verify each phase completion before proceeding

Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
Generate a custom checklist for the current feature based on user requirements.
