The autonomous build contract, out of the box — "/brain-build <what you want>" activates the disciplined hands-off build power users used to hand-write a standing prompt for. Use when the user says "/brain-build", "brain build", "build this autonomously", "build this hands-off", "loop until it's done", "don't ask me, just build it", or asks for an unattended/self-grading build. Phase-gated per rUv's SPARC, self-verified and self-graded /100 against a per-phase rubric (below 95 → fix and regrade, max 5 iterations), cost-tier routed with printed receipts, crash-resumable via checkpoints, questions batched into one list — the user writes the goal, not the contract.

From the source SKILL.md

<!-- Credit: this contract productizes a community field pattern — the 7-rule standing prompt hand-written by the PR #8 contributor (Eva Draganova, 2026-07-10) to force the brain into disciplined autonomous building. Her forcing insight: "grade 1-100, no pass under 95 → forced it to loop and improve." All the machinery existed; this skill removes the 40 hand-written lines needed to activate it. -->

What this skill does

Brain Build is a community-contributed Claude Code skill in the education-learning sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/brain-build/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user says "/brain-build", "brain build", "build this autonomously", "build this hands-off", "loop until it's done", "don't ask me, just build it", or asks for an unattended/self-grading build. Phase-gated per rUv's SPARC, self-verified and self-graded /100 against a per-phase rubric (below 95 → fix and regrade, max 5 iterations), cost-tier routed with printed receipts, crash-resumable via checkpoints, questions batched into one list — the user writes the goal, not the contract.

It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 157,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

When should I use the Brain Build skill?

Browse related skills at /category/general/.
What is a Claude Code skill and how does the Brain Build 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).
