best-practices

A set of writing and coding rules that reduces patterns often associated with AI-generated text.

In plain words
What is it for?
Use it to guide generated README files, docs, code comments, commit messages, and other project text.
Why use it?
It helps keep documentation, comments, commits, and other prose from sounding repetitive, inflated, or machine-written.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

best-practices 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

  • Never use em dashes (—) as separators. Use hyphens with spaces ( - ), periods, or restructure the sentence.
  • Never use these words: delve, tapestry, leverage, utilize, facilitate, streamline, paramount, pivotal, meticulous, holistic, robust, comprehensive, multifaceted, harness, foster, bolster, seamless, cutting-edge, game-changing, revolutionary, groundbreaking, nuanced, intricate, elevate, empower, unleash.
  • Never open with "In today's...", "It's worth noting...", "Let me explain...", "At its core..." or close with "In summary...", "Happy coding!", "In conclusion...".
  • Never add narrating code comments that describe what the code does. Only comment non-obvious intent, constraints, or trade-offs.
  • Never add git co-author trailers for AI tools (Co-authored-by: Cursor, Copilot, etc.) or "Generated by" attribution.
  • Vary sentence length. Mix short direct statements with longer ones. Never write 4+ sentences of similar length in a row.
  • Use plain words. "important" not "paramount", "careful" not "meticulous", "use" not "leverage", "improve" not "optimize".
  • Keep commit messages short and lowercase. No marketing language in commit bodies.
  • Never over-format: no bold-label bullets (Feature: desc), no uniform list lengths, no tricolons in every list.
  • Write READMEs and docs in a direct, sparse style. State what the thing does, not why it's amazing.

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.

best-practices is a cursor rule published in the GitHub repository ofershap/ai-humanizer (4 stars, last pushed 6mo ago), licensed MIT. It adds 349 tokens to every session, about $0.0017 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.
