Delegation

For detailed specification writing workflows, this skill delegates to spec-kit:spec-writing as the canonical implementation. Use this skill for quick specification needs; use spec-kit for thorough specification documents.

When To Use

After brainstorming phase completes
Have project brief but need detailed requirements
Need testable acceptance criteria for implementation
Planning validation and testing strategy
Translating business requirements into technical specs
Defining scope boundaries and out-of-scope items

When NOT To Use

Still exploring problem space (use Skill(attune:project-brainstorming) instead)
Already have detailed specification (use Skill(attune:project-planning) instead)
Refining existing implementation (use code review skills)
Making strategic decisions (use Skill(attune:war-room) for complex choices)

Integration

With spec-kit:

Delegates to Skill(spec-kit:spec-writing) for methodology
Uses spec-kit templates and validation
Enables clarification workflow

Without spec-kit:

Standalone specification framework
Requirement templates
Acceptance criteria patterns

Documentation Audience

Carry the brief's Doc audience field into the specification, and treat it as a requirement rather than a note: it decides what the project's README, guides, and tutorials may contain. When the brief did not set one, ask, do not guess.

Specify the deep-dive destination alongside it, so extraction has
