User Input

$ARGUMENTS

You MUST consider the user input before proceeding (if not empty).

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

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:

     | 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

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.

10. 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
