Autospec Specify

autospec-specify

This Agent Skill is generated from autospec.specify. When the user invokes "$autospec-specify" or "/autospec.specify", load and follow these instructions directly. Treat the text after the skill or command name as "$ARGUMENTS". Do not route back through "autospec specify"; this skill is the prompt for the stage.

User Input

$ARGUMENTS

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

Outline

The text the user typed after $autospec-specify in the triggering message is the feature description. Assume you always have it available in this conversation even if $ARGUMENTS appears literally below. Do not ask the user to repeat it unless they provided an empty command.

Given that feature description, do this:

1. Generate a concise short name (2-4 words) for the branch:

   • Analyze the feature description and extract the most meaningful keywords
   • Create a 2-4 word short name that captures the essence of the feature
   • Use action-noun format when possible (e.g., "add-user-auth", "fix-payment-bug")
   • Preserve technical terms and acronyms (OAuth2, API, JWT, etc.)
   • Keep it concise but descriptive enough to understand the feature at a glance
   • Examples:
     • "I want to add user authentication" → "user-auth"
     • "Implement OAuth2 integration for the API" → "oauth2-api-integration"
     • "Create a dashboard for analytics" → "analytics-dashboard"
     • "Fix payment processing timeout bug" → "fix-payment-timeout"

2. Create feature branch and directory: Run the Go command with your generated short-name:

   autospec new-feature --json --short-name "<short-name>" "$ARGUMENTS"

   Parse the JSON output for:

   • BRANCH_NAME: The full branch name (e.g., "008-user-auth")
   • SPEC_FILE: Path to the spec file (ignore - we'll create spec.yaml instead)
   • FEATURE_NUM: The feature number
   • AUTOSPEC_VERSION: The autospec version (for _meta section)
   • CREATED_DATE: ISO 8601 timestamp (for _meta section)

   Set FEATURE_DIR to specs/<BRANCH_NAME>/

3. Generate spec.yaml: Create the YAML specification file with this exact structure.

   The structure below is the authoritative schema; follow it directly. Optionally run autospec artifact spec --schema for field details; if that probe is unavailable or fails in your environment, continue with the structure below and rely on the validation step instead.

4. Follow this execution flow:

   1. Parse user description from Input If empty: ERROR "No feature description provided"
   2. Extract key concepts from description Identify: actors, actions, data, constraints
   3. For unclear aspects:
      • Make informed guesses based on context and industry standards
      • Only mark with clarification_needed: "<specific question>" if:
        • The choice significantly impacts feature scope or user experience
        • Multiple reasonable interpretations exist with different implications
        • No reasonable default exists
      • LIMIT: Maximum 3 clarification_needed markers total
      • Prioritize clarifications by impact: scope > security/privacy > user experience > technical details
   4. Fill user_stories section If no clear user flow: ERROR "Cannot determine user scenarios"
   5. Generate functional requirements Each requirement must be testable Use reasonable defaults for unspecified details (document in assumptions)
   6. Define success_criteria Create measurable, technology-agnostic outcomes Include both quantitative metrics (time, performance, volume) and qualitative measures Each criterion must be verifiable without implementation details
   7. Identify key_entities (if data involved)
   8. Document edge_cases, assumptions, constraints, out_of_scope

5. Write the specification to FEATURE_DIR/spec.yaml

6. ⚠️ MANDATORY: Validate the artifact (skipping this WILL cause task failure and retry):

   autospec artifact FEATURE_DIR/spec.yaml

   • If validation fails: Read the error output carefully. Fix ALL schema errors (missing required fields, wrong enum values, invalid types) and re-run validation until it passes.
   • If validation passes: Proceed to report.
   • Do NOT skip this step - post-execution validation will catch errors and force a full retry.

   Common validation errors:

   • Missing required field (e.g., user_stories[0].priority) → add the field
   • Invalid enum value (e.g., priority: "High") → use valid value (P0, P1, P2, P3)
   • Wrong type (e.g., user_stories is object instead of array) → fix structure

7. Report: Output:

   • Branch name created
   • Full path to spec.yaml
   • Summary of user stories and requirements count
   • Any clarification_needed items found
   • Readiness for $autospec-plan
