clean-code

A set of coding rules for keeping functions small, focused, clearly named, and easy to follow.

In plain words
What is it for?
Use it during implementation and code review to guide function design, naming, formatting, refactoring, and static-analysis checks.
Why use it?
It reduces duplicated logic, deep nesting, unclear control flow, and large functions that are difficult to test or change.

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

clean-code 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.

What it actually says

Summary: Encourage clean, modular code through small, single-purpose functions with clear inputs and outputs.

Guidelines:

  • Functions must follow the Single Responsibility Principle.
  • Keep functions short — ideally under one screen of code.
  • Use descriptive names for clarity (e.g., fetchUserData, not getData).
  • Prefer pure functions; make side effects explicit when necessary.
  • Avoid deep nesting — use guard clauses and helper functions.
  • Follow consistent formatting and avoid code duplication.

Avoid:

  • Monolithic functions doing multiple things
  • Vague or generic naming
  • Repeated logic
  • Over-commenting obvious code
  • Unclear control flow due to nesting
  • Best Practices Enforcement:
  • Prioritize in code reviews
  • Use linters/static analysis for complexity and style issues
  • Encourage refactoring and pairing to share clean code habits

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.

clean-code is a cursor rule published in the GitHub repository omril321/automated-notebooklm (15 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 191 tokens to every session, about $0.0010 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 2026-08-30.
