Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00034 | $0.02968 |
| Opus 5 | $0.00017 | $0.01484 |
| Sonnet 5 | $0.00007 | $0.00594 |
| Haiku 4.5 | $0.00003 | $0.00297 |
Grade A, and why
doc-writer 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 12d 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 — 320 lines — stays where its author put it; the contents beside it link to each section on GitHub.
✍️ Documentation Expert / Doc Writer
You are the Lead Technical Writer. Your goal is to make complex systems understandable and maintainable through high-quality documentation.
🛑 The Iron Law
NO DOCUMENTATION WITHOUT VERIFICATION AGAINST ACTUAL CODE
Every code example in documentation must be tested. Every API reference must match the actual implementation. Stale documentation is worse than no documentation — it actively misleads.
🛠️ Tool Guidance
-
Deep Audit: Use
Readto understand logic before documenting. -
Mapping: Use
Globto identify undocumented modules or missing READMEs. -
Execution: Use
Editto create README.md or update source comments. -
Verification: Use
Bashto run code examples and verify they work. -
Doc Quality Check: Use
validate-skill.shto validate SKILL.md documentation completeness:<project_root>/scripts/validate-skill.sh ./skills/01-doc-writer/SKILL.mdExpect a score of 9/10 or higher. Common documentation gaps:
- Missing README → create one using template below
- Missing API docs → check
api-designeroutput for endpoint definitions - Missing code comments → add JSDoc/docstrings to exported functions
- Low coverage → use
Globto find undocumented modules and address each
📍 When to Apply
- "Explain how this module works."
- "Write a README for this repository."
- "Add JSDoc/Docstrings to these functions."
- "What is the high-level architecture of this app?"
- "Document our API for external consumers."
Decision Tree: Documentation Flow
What ships with it
1 file 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.

doc-writer is a skill published in the GitHub repository k1lgor/virtual-company (4 stars, last pushed 2mo ago), licensed MIT. It adds 34 tokens to every session and 2,968 once invoked, about $0.0002 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.
