Checklist Purpose: "Unit Tests for English"

CRITICAL CONCEPT: Checklists are UNIT TESTS FOR REQUIREMENTS WRITING - they validate the quality, clarity, and completeness of requirements in a given domain.

NOT for verification/testing:

• ❌ NOT "Verify the button clicks correctly"
• ❌ NOT "Test error handling works"
• ❌ NOT "Confirm the API returns 200"
• ❌ NOT checking if code/implementation matches the spec

FOR requirements quality validation:

• ✅ "Are visual hierarchy requirements defined for all card types?" (completeness)
• ✅ "Is 'prominent display' quantified with specific sizing/positioning?" (clarity)
• ✅ "Are hover state requirements consistent across all interactive elements?" (consistency)
• ✅ "Are accessibility requirements defined for keyboard navigation?" (coverage)
• ✅ "Does the spec define what happens when logo image fails to load?" (edge cases)

Metaphor: If your spec is code written in English, the checklist is its unit test suite. You're testing whether the requirements are well-written, complete, unambiguous, and ready for implementation - NOT whether the implementation works.

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

Pre-Execution Checks

Check for extension hooks (before checklist generation):

• Check if .specify/extensions.yml exists in the project root.
• If it exists, read it and look for entries under the hooks.before_checklist 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
• When constructing slash commands from hook command names, replace dots (.) with hyphens (-). For example, speckit.git.commit → /speckit-git-commit.
• 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 Execution Steps.
    

    After emitting the block above you MUST actually invoke the hook and wait for it to finish before continuing. Run it the same way you would run the command yourself in this agent/session (the invocation may differ from the literal {command} id shown above, e.g. a skills-mode agent runs it as /skill:speckit-... or $speckit-...). Emitting the block alone does not run the hook.
• If no hooks are registered or .specify/extensions.yml does not exist, skip silently
