Spec Creation

Overview

Creates comprehensive feature specifications by first deeply researching the codebase, then generating structured specifications with requirements, acceptance criteria, architecture decisions, and phased implementation plans.

Research Phase

  • Analyze project structure and module organization
  • 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

  • claudekit-spec-workflow (create mode)
