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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00040 | $0.00669 |
| Opus 5.5 | $0.00016 | $0.00268 |
| Sonnet 5.5 | $0.00008 | $0.00134 |
| Haiku 4.5 | $0.00004 | $0.00067 |
Grade A, and why
natural-writing 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Natural Writing
Core principle
Write like a thoughtful person speaking: connect related ideas; preserve meaning and voice, not punctuation or clause inventory.
Prefer literal language when it is clearer
Remove mannered prose: metaphor or flourish that replaces a clearer literal statement. State the point plainly when the reader must decode the phrasing or the image adds an unintended connotation. Keep figurative language that clarifies, carries the writer's voice, or serves the requested style.
Attach conditions to their outcome
Put conditions and their outcome or decision in one sentence.
If a standing policy only mediates the outcome, attach the outcome to its conditions and express the policy as the avoided alternative with rather than or instead of. Keep it separate when announcing, defending, or changing it is the point.
Do not fuse unrelated events, next steps, or deliberate formality.
Preserve material meaning
Preserve facts, commitments, boundaries, requests, numbers, tense, uncertainty, perspective, and tone. A detail is material when removing it changes what the reader believes or does.
Method
- Identify reader, purpose, action, and register.
- Map qualification, contrast, cause, outcome, shared history, consequence, and next step.
- Rebuild complete spoken thoughts:
- Keep qualifications and contrasts with what they change.
- Group alternative causes with
orand carry them into their shared outcome. - Start a new sentence only for a genuine change in thought.
- For sensitive writing, use only true shared context. Keep sincere acknowledgment separate from criticism; do not use it as the setup for
but. Enter the unwanted result with an earned bridge, then state the consequence and request. One acknowledgment is enough. - Prefer plain words, contractions, direct verbs, varied lengths, and supported consequences. Remove filler, puffery, reassurance, repetition, jargon, synonym cycling, and robotic symmetry.
- Run the structural audit below. Rewrite every failure before returning the draft.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

natural-writing is a skill published in the GitHub repository mike-coulbourn/claude-vibes (44 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 669 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-22.
