Illustrative result — not a recorded session
This example describes the deliverable to expect for the request above. It is not a claim that this feature has been implemented or tested in a real repository. Actual files, checks, and PR links depend on your project.
Deliverable
An open pull request adding CSV export to the invoices list, following the project’s existing UI, data access, and file download conventions. The PR explains the exported fields, which invoices are included, and how the implementation handles empty lists and special characters.
Work and decisions
The lead agent coordinates exploration, implementation, verification, and any required review. Reversible implementation choices follow local conventions. Any unresolved product decision is raised before dependent work proceeds.
Verification evidence
The real result lists the checks actually run on the delivered commit, their outcomes, and any material gaps. A separate verifier runs the relevant tests, CI checks, and real entry point when available. No test counts or success claims are invented.
Next step
Review the linked PR and its evidence, then decide whether to merge. BigBrain stops at the open pull request and never merges or force-pushes.

About this skill
BigBrain is an engineering skill for coding agents. Give it a feature, bug, refactor, or chore: the main agent leads the work, delegates exploration, implementation, verification, and review to specialist subagents, and brings back an open pull request with the decisions and evidence.
What it does
- Builds features, fixes bugs, refactors code, and handles maintenance tasks.
- Plans larger changes as smaller, verifiable steps and executes saved plan slices.
- Explains how code works and why it was written that way.
- Challenges ideas, critiques changes, and prepares guided PR reviews in your browser.
- Watches pull requests and resumes earlier work.
How it works
Clear requests run autonomously. BigBrain asks when a product or scope decision needs your input. A separate verifier checks tests, CI, and the real entry point when available; risky changes also get reviewers. Implemented changes stop at an open PR: BigBrain never merges or force-pushes. Planning, explanations, reviews, and idea discussions stop at their own result.
Getting started
Install with npx skills add LeoMartinDev/skills -g, optionally run /bigbrain setup to choose models per role, then invoke /bigbrain followed by your request. It accepts plain text, a GitHub issue URL, a Notion page, or a saved plan.
Inspired by pstack by poteto (Lauren Tan). BigBrain is a standalone skill and does not require pstack.
