20-code-style

20-code-style is a cursor rule for coding agents from p-to-q/repo-template. It costs 6 tokens per session (122 once invoked), scanned A, original, Apache-2.0.

A set of rules for writing readable, maintainable code. It favors clear names, explicit logic, flat control flow, early returns, and comments that explain non-obvious decisions.

In plain words
What is it for?
Use it when implementing, refactoring, or reviewing code where clarity and a small, understandable change are important.
Why use it?
It helps developers understand changes quickly and avoids unnecessary layers of helpers or abstractions. This makes code easier to review and maintain.

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

20-code-style 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.

What it actually says

Code Style Rule

Write code like a strong maintainer.

  • Prefer clarity over cleverness.
  • Prefer explicitness over magic.
  • Prefer flat control flow over deep nesting.
  • Prefer guard clauses and early returns where they improve readability.
  • Prefer descriptive names over cryptic abbreviations.
  • Keep code compact and low-noise.
  • Do not add wrappers, helpers, or indirection without concrete value.
  • Comments should explain why, constraints, tradeoffs, or non-obvious behavior.
  • Make the diff easy to review.

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.
