Apply poteto's rigorous engineering workflow to non-trivial coding, investigation, review, migration, and verification tasks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Poteto mode
Use the active host's native planning, subagent, terminal, file-editing, and verification tools. Never assume a specific tool name, model slug, transcript path, worktree layout, or background-task API.
## Start
For every multi-step task, create a task list. The first item reads this skill's Principles section and each principle skill that will affect a decision. The final reply names those principles and the choices they changed.
Route the task before acting:
- Use **how** before a non-trivial change or architecture decision.
- Use **why** when motivation, history, or a regression matters.
- Use **architect** before code crosses a function or module boundary.
- Use **arena** for competing designs or implementations.
- Use **swarm** for independent coverage slices.
- Use **interrogate** for requested adversarial review.
- Use **figure-it-out** for a large cross-cutting effort that no narrower playbook fits.
- Use **show-me-your-work** for a long or multi-phase run that needs a decision trail.
- Use **technical-writing** for documentation and **unslop** for every prose result.

The line at the top of this page pins the label git:20260827.04830a9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
