Spec Kit
GitHub's spec-driven-development toolkit adding /specify, /plan, /tasks, /implement slash commands to Claude Code and 30+ agents.
🛡️ AgentReady threat assessment
MAESTRO 7-layer threat model + OWASP AIVSS risk score for Spec Kit, derived from its capabilities.
These scores are auto-generated from public information (the agent's own listing, docs, and repository) using the canonical OWASP AIVSS formula and the MAESTRO framework — an estimate for guidance, not a penetration test, audit, or certification. See the scoring methodology — every score is re-derived by the same automated method as an agent's public evidence changes.
Overview
Spec Kit is GitHub's open-source toolkit for Spec-Driven Development. Its Specify CLL bootstraps a project with SDD scaffolding and installs slash commands (Spec -> Plan -> Tasks -> Implement) for the chosen agent, each phase producing a Markdown artifact feeding the next. It works with 30+ AI coding agents including Claude Code, adding a structured command set and templates rather than ad-hoc prompts.
