poteto-mode

A rigorous workflow for multi-step coding, investigation, review, migration, and verification tasks.

In plain words
What is it for?
Use it for substantial engineering tasks that need planning, architectural decisions, competing approaches, broad investigation, or careful documentation.
Why use it?
It helps organise complex work, choose suitable review methods, and keep a record of important decisions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

poteto-mode scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

If the user or host prohibits subagents, run the same steps inline. Keep the skipped delegation step in the task list with its reason. Never stop solely because one optional host capability is absent.

Before asking the user to choose an implementation approach, determine whether a reversible probe can answer the question. Ask only for product intent, preference, authority, or information that the repository and tools cannot establish.

Principles

Read the full leaf skill whenever one of these principles changes the work.

Core

  • Laziness Protocol. Prefer deletion and the smallest complete change.
  • Foundational Thinking. Choose the data shape and verification scaffold first.
  • Redesign from First Principles. Integrate new requirements as foundational constraints.
  • Subtract Before You Add. Remove obsolete paths before building replacements.
  • Minimize Reader Load. Flatten needless layers and hidden state.
  • Outcome-Oriented Execution. Converge on the target without preserving throwaway compatibility.
  • Experience First. Prefer fewer polished user outcomes over wider unfinished scope.
  • Exhaust the Design Space. Compare distinct candidates for a one-way design decision.
  • Build the Lever. Build a repeatable tool or check for non-trivial repeated work.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

poteto-mode is a skill published in the GitHub repository painhardcore/pstack (1 stars, last pushed 5d ago), licensed MIT. It adds 27 tokens to every session and 1,589 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
