  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

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)
