Specify — Specification Creator

What it does

Specify turns a brief description into a full specification workflow. It guides the agent through initialization, research, and a three-phase write process (PRD → SDD → PLAN), scaffolding directories and README tracking, and ensuring decisions are recorded. The skill delegates research to specialised sub-agents, suggests the appropriate mode (Standard vs Agent Team), and strictly enforces phase-by-phase progression and user confirmations.

When to use it

Use Specify when you need a repeatable, auditable specification process for a new feature, product, or integration. Ideal for projects that need clear separation between business requirements (PRD), technical design (SDD), and implementation planning (PLAN), or when multiple perspectives must be synthesized by specialist agents.

What's included

• Scripts: No dedicated scripts detected (has_scripts=false)
• References: reference/ and examples/ directories suggested in the skill body
• Instructions: step-by-step workflow covering initialization, mode selection, research orchestration, writing each document phase, git options for commits/PRs, and finalization checks. It also prescribes constraints (what to always/never do) and output formatting for README-based decision tracking.

Compatible agents

Optimised for agent runtimes that support spawning sub-agents and file IO (e.g., Claude Code, agentic runtimes that support sessions_spawn). The workflow assumes the agent can run shell/git commands and manage local .start/docs directories.
