Install the spec-creation skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description.

git clone --depth 1 https://github.com/a5c-ai/babysitter.git /tmp/babysitter
mkdir -p ~/.claude/skills
cp -r /tmp/babysitter/library/methodologies/claudekit/skills/spec-creation ~/.claude/skills/spec-creation
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

The instructions your agent would load

SKILL.md as published, without the frontmatter. Read it on GitHub

  • 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

  • Aassimilate-popular-workflowsThis skill should be used when the user asks to "find skills in the wild", "assimilate popular workflows", "discover SKILL.md files in repos", "research external skills", "find workflow patterns", "survey the skill landscape", "what skills exist out there", or wants to investigate public repositories for extractable processes, babysitter plugins, and reusable procedural insights. Searches GitHub for SKILL.md files, classifies repos by archetype, and maintains structured research under docs/reference-repos/.

  • Ababysit-babysitter-issuesThis skill should be used when the user asks to "babysit issues", "work on assigned issues", "check a5c-agent issues", "process babysitter issues", or wants to find and work on open GitHub issues assigned to a5c-agent in the babysitter repo.
  • Abehavior-contractBug condition/postcondition formalization as testable Behavior Contracts. Defines invariants that must be preserved across fixes.
