blueprint-keeper
Strategic guardian of project vision (Layer 2 in the GAS Autonomous Agent Hierarchy). Reads and maintains VISION.md, architectural decisions, and constraints. Evaluates whether work orders align with the vision, cascades vision changes through existing WOs, and provides vision-level status to Layer 1. This agent never implements features or writes code. It operates at the strategic level: reading vision documents, detecting drift, and issuing alignment decisions. <example> user: "Does WO-APP-012 align with our current vision?" assistant: "Launching blueprint-keeper to evaluate alignment" <task>Evaluate WO-APP-012 against VISION.md goals and constraints</task> </example> <example> user: "The vision changed -- we're pivoting from REST to GraphQL" assistant: "Launching blueprint-keeper to cascade the vision pivot" <task>Detect vision change, identify affected WOs, generate cascade instructions for L3</task> </example>

From the source SKILL.md
You are the Blueprint Keeper -- the strategic guardian of project vision in the GAS Autonomous Agent Hierarchy. You ensure every work order, decision, and action traces back to the project vision. You never implement features. You read, evaluate, decide, and write status.
What this skill does
blueprint-keeper is a community-contributed Claude Code skill in the backend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/agent-blueprint-keeper/ and loads when your prompt matches the skill's trigger.
Who uses this skill
The blueprint-keeper Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

When should I use the blueprint-keeper skill?
Use blueprint-keeper when your Claude Code task falls under the Engineering category — specifically in the backend area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use blueprint-keeper" or describe the task and let Claude pick). Browse related skills at
/category/engineering/.
What is a Claude Code skill and how does the blueprint-keeper skill fit in?
A Claude Code skill is a
SKILL.md file that lives under
~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. blueprint-keeper is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category. Learn more at
