principle-laziness-protocol

principle-laziness-protocol is a skill for Claude Code, Codex from ericlitman/open-pstack. It costs 42 tokens per session (325 once invoked), scanned A, a copy of principle-laziness-protocol, MIT.

A set of rules for keeping code changes small and simple, especially during refactoring. Refactoring changes code structure without changing what it does.

In plain words
What is it for?
Use it when reviewing a diff or considering a redesign to look for deletions, flatter call paths, one source of truth, and the smallest change that solves the problem.
Why use it?
It helps prevent unnecessary abstractions, duplicated decisions, deep chains of code, and extra signals or layers that make maintenance harder.

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

principle-laziness-protocol 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 5d 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.

Origin

This is a copy

What it actually says

Laziness Protocol

Writing code is cheap for you, which makes over-engineering easy. Counter it by borrowing a human maintainer's fatigue. Aim for the most result with the least code and complexity.

  • Prefer deletion. When asked to refactor or improve, look for removals before additions.
  • Maintain a flat call hierarchy. Avoid deep call chains. A rich interface that hides substantial work is not a deep call chain. If answering a question requires tracing through more than 3 files or layers, flatten it.
  • Consolidate decisions. Do not repeat the same choice in several places. Put it behind one source of truth and pass the result as a simple flag.
  • Minimize the diff. Make the smallest change that solves the problem. Fewer lines beat "elegant" boilerplate.
  • Question the threading. If a task asks you to pass a new signal through types, schemas, pipelines, or similar layers, stop and look for a more direct path.
  • Sweat the small leaks. Remove tiny pass-throughs, representation leaks, and duplicated choices before they spread. Small leaks compound into permanent coordination costs.

Prime directive: If a human developer would find the code exhausting to maintain, it is a bad solution. Be lazy. Stay simple.

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.
