spec-creation

SkillDev tools

Lets your agent research a codebase and write feature specs with requirements, acceptance criteria, and plans.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the spec-creation skill

About this capability

Feature specification creation from codebase research. Produces requirements, acceptance criteria, architecture decisions, implementation plans, and risk analysis.

What this skill tells your AI

The instructions your AI receives, as published by a5c-ai/babysitter in library/methodologies/claudekit/skills/spec-creation/SKILL.md and read by ahel’s review.

  • Identify existing patterns and conventions
  • Map dependencies and integration points
  • Review existing tests for testing patterns
  • Document technical constraints

Specification Components

Scope and Non-Goals

Clear boundaries on what the feature does and does not include.

Functional Requirements

Detailed requirements with unique identifiers for tracking.

Acceptance Criteria

Testable, measurable criteria for each requirement.

Architecture Decisions

Decision records with rationale and alternatives considered.

Implementation Plan

Phased approach ordered by dependency, not priority.

Risk Analysis

Identified risks with probability, impact, and mitigation strategies.

API Contracts and Data Models

Interface definitions and data model schemas.

Test Strategy

Mapping of unit, integration, and E2E tests to requirements.

Output

Specifications are saved to docs/specs/{feature}.md for reference by the execution workflow.

When to Use

  • /spec:create [feature] slash command
  • Before starting a new feature implementation
  • When planning complex multi-module changes

Processes Used By
