Pre-Execution Checks

Check for extension hooks (before implementation):

Check if .specify/extensions.yml exists in the project root.
If it exists, read it and look for entries under the hooks.before_implement key
If the YAML cannot be parsed or is invalid, skip hook checking silently and continue normally
Filter out hooks where enabled is explicitly false. Treat hooks without an enabled field as enabled by default.
For each remaining hook, do not attempt to interpret or evaluate hook condition expressions:
- If the hook has no condition field, or it is null/empty, treat the hook as executable
- If the hook defines a non-empty condition, skip the hook and leave condition evaluation to the HookExecutor implementation

For each executable hook, output the following based on its optional flag:

Optional hook (optional: true):

## Extension Hooks

**Optional Pre-Hook**: {extension}
Command: `/{command}`
Description: {description}

Prompt: {prompt}
To execute: `/{command}`

Mandatory hook (optional: false):

## Extension Hooks

**Automatic Pre-Hook**: {extension}
Executing: `/{command}`
EXECUTE_COMMAND: {command}

Wait for the result of the hook command before proceeding to the Outline.

If no hooks are registered or .specify/extensions.yml does not exist, skip silently

Outline

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").
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:
```
| 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
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
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):
```
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*
- Python: __pycache__/, *.pyc, .venv/, venv/, dist/, *.egg-info/
- Java: target/, *.class, *.jar, .gradle/, build/
- C#/.NET: bin/, obj/, *.user, *.suo, packages/
- Go: *.exe, *.test, vendor/, *.out
- Ruby: .bundle/, log/, tmp/, *.gem, vendor/bundle/
- PHP: vendor/, *.log, *.cache, *.env
- Rust: target/, debug/, release/, *.rs.bk, *.rlib, *.prof*, .idea/, *.log, .env*
- Kotlin: build/, out/, .gradle/, .idea/, *.class, *.jar, *.iml, *.log, .env*
- C++: build/, bin/, obj/, out/, *.o, *.so, *.a, *.exe, *.dll, .idea/, *.log, .env*
- C: build/, bin/, obj/, out/, *.o, *.a, *.so, *.exe, *.dll, autom4te.cache/, config.status, config.log, .idea/, *.log, .env*
- Swift: .build/, DerivedData/, *.swiftpm/, Packages/
- R: .Rproj.user/, .Rhistory, .RData, .Ruserdata, *.Rproj, packrat/, renv/
- Universal: .DS_Store, Thumbs.db, *.tmp, *.swp, .vscode/, .idea/
Tool-Specific Patterns:
- Docker: node_modules/, .git/, Dockerfile*, .dockerignore, *.log*, .env*, coverage/
- ESLint: node_modules/, dist/, build/, coverage/, *.min.js
- Prettier: node_modules/, dist/, build/, coverage/, package-lock.json, yarn.lock, pnpm-lock.yaml
- Terraform: .terraform/, *.tfstate*, *.tfvars, .terraform.lock.hcl
- Kubernetes/k8s: *.secret.yaml, secrets/, .kube/, kubeconfig*, *.key, *.crt
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
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
Implementation execution rules:
- Setup first: Initialize project structure, dependencies, configuration
- Tests before code: If you need to write tests for contracts, entities, and integration scenarios
- Core development: Implement models, services, CLI commands, endpoints
- Integration work: Database connections, middleware, logging, external services
- Polish and validation: Unit tests, performance optimization, documentation
Progress tracking and error handling:
- Report progress after each completed task
- Halt execution if any non-parallel task fails
- For parallel tasks [P], continue with successful tasks, report failed ones
- Provide clear error messages with context for debugging
- Suggest next steps if implementation cannot proceed
- IMPORTANT For completed tasks, make sure to mark the task off as [X] in the tasks file.
Completion validation:
- Verify all required tasks are completed
- Check that implemented features match the original specification
- Validate that tests pass and coverage meets requirements
- Confirm the implementation follows the technical plan
- Report final status with summary of completed work

Note: This command assumes a complete task breakdown exists in tasks.md. If tasks are incomplete or missing, suggest running /speckit.tasks first to regenerate the task list.

Check for extension hooks: After completion validation, check if .specify/extensions.yml exists in the project root.
- If it exists, read it and look for entries under the hooks.after_implement key
- If the YAML cannot be parsed or is invalid, skip hook checking silently and continue normally
- Filter out hooks where enabled is explicitly false. Treat hooks without an enabled field as enabled by default.
- For each remaining hook, do not attempt to interpret or evaluate hook condition expressions:
  - If the hook has no condition field, or it is null/empty, treat the hook as executable
  - If the hook defines a non-empty condition, skip the hook and leave condition evaluation to the HookExecutor implementation
- For each executable hook, output the following based on its optional flag:
  - Optional hook (optional: true):
```
## Extension Hooks

**Optional Hook**: {extension}
Command: `/{command}`
Description: {description}

Prompt: {prompt}
To execute: `/{command}`
```
  - Mandatory hook (optional: false):
```
## Extension Hooks

**Automatic Hook**: {extension}
Executing: `/{command}`
EXECUTE_COMMAND: {command}
```
- If no hooks are registered or .specify/extensions.yml does not exist, skip silently
