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

create-doc 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 5d 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.

The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create Documentation

Activation

This skill activates for:

  • Creating a new documentation file
  • Documenting a feature, a concept, or a component
  • /create-doc

Persona

Read .claude/roles/documentalist.md — adopt this profile and follow all its rules.

Workflow

Step 1: Clarify the Subject

If the subject is vague, ask:

  • Which component/feature to document?
  • Target audience: contributor, user, LLM?
  • Scope: reference, guide, architecture, or spec?

Step 2: Detect Duplicates

MANDATORY before any creation.

# List all existing docs
Glob docs/**/*.md

# Read the titles and H2/H3 of each file
# Compare with the requested subject

If an existing doc already covers the subject:

  • STOP — do not create a new file
  • Suggest updating the existing doc via /update-docs
  • Explain which file covers what

If partial overlap:

  • Identify precisely which sections already exist
  • The new doc must cover ONLY the missing content
  • Add links to existing sections

Step 3: Create the File

Apply the template from PERSONA.md:

---
title: <Title>
scope: reference | guide | architecture | spec
related:
  - src/path/to/source.ts
  - docs/RELATED-DOC.md
last-updated: YYYY-MM-DD
---

Writing rules:

  • English only
  • 1-2 summary sentences after the title
  • One section = one concept
  • Tables rather than lists for structured data
  • Code blocks rather than prose for technical details
  • Max 800 words — split if longer

Step 4: Naming

Location Convention
docs/ top-level SCREAMING-KEBAB.md (e.g., MCP-TOOLS-REFERENCE.md)
Subdirectory kebab-case.md (e.g., docs/mcp/architecture.md)

Step 5: Update the Index

Run /docs-index to regenerate docs/INDEX.md with the new file.

Anti-patterns

Forbidden Do Instead
Duplicate existing content Link to the canonical source
Doc > 800 words Split into multiple files
Sections unrelated to the title Create a separate doc
Prose when a table suffices Use a table
Mixing French and English Everything in English

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.
