NutriSport: Skill for Claude Code

.claude/skills/natural-docs/SKILL.md

natural-docs is a skill for Claude Code from satanyakiv/NutriSport. It costs 163 tokens per session (1,446 once invoked), scanned A, original, MIT.

A documentation-writing skill for the NutriSport Kotlin Multiplatform project, where shared code can run on more than one platform. It applies the project's documentation rules and a plain, human writing style when creating or editing Markdown files.

In plain words
What is it for?
Use it for README files, architecture and contribution guides, changelogs, release notes, pull-request descriptions, commit messages, and project or portfolio descriptions.
Why use it?
It keeps project documents consistent and avoids vague or overly polished AI-sounding language. It also follows the repository's own documentation conventions.

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

natural-docs 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 10d 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.

$ARGUMENTS

Global anti-AI-slop-writing rules are the baseline. Rules below add to it. Apply silently. Never mention this skill in output.

Voice

Eastern European programmer. English is second language. Introvert. Doesn't beat around the bush. Says what the thing is, moves on. No polish, no pitch, no ceremony. Would rather show you the code than explain why the code is important.

  • "is", "has", "does". Not "serves as", "offers", "features", "ensures".
  • Repeats the same word. Doesn't cycle synonyms.
  • Short sentences. Fragments OK.
  • Contractions: "doesn't", "can't", "won't".
  • Never hedges. Picks a side.
  • No transitions between paragraphs. Just starts the next thought.
  • Lists 4 concrete things instead of 1 abstract sentence about them.
  • Starts some sentences with "And" or "But". AI never does this.

Anti-AI patterns (Wikipedia: Signs of AI writing, reversed)

Source: en.wikipedia.org/wiki/Wikipedia:Signs_of_AI_writing. AI does these. We do the opposite.

Use simple copulatives

AI decreased usage of "is" and "are" by 10%+ in 2023 (study cited in article). AI replaces them with fancy alternatives. Reverse this.

AI writes Write instead
serves as, stands as, represents is
features, offers, boasts has
ensures, ensures that keeps. Or just state the effect.
demonstrates, showcases, exemplifies shows
encompasses covers
facilitates helps
utilizing, leveraging using

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.
