Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: names the AskUserQuestion tool; installed under .agents/ (shared by several agents).

This is sabertaz/notes's own configuration. It tells Claude Code how to work on notes itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything notes configures →

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

adding-notes 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 2mo 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

Adding Notes

Identify the core concept from the user's content, find the best existing file and section, insert concisely.

Core Principle: Concept ≠ Example

The #1 mistake: treating the example subject as the topic.

User provides:  systemctl cat paccache.service
❌  → new "paccache" section
✅  → existing "systemctl cat" section (paccache is just an example)

User provides:  nginx.conf gzip settings
❌  → new "gzip-config.md"
✅  → existing web/nginx/ section

Ask yourself: Does this knowledge apply to any instance, or only this specific one? If "any" → put it with the tool/concept, not the example.

Workflow

  1. Identify concept — commands → the command; config → the tool; errors → the pattern; code → the feature
  2. Locate target — Grep/Glob for the concept in content/{ai,cs,language,programming,web}/. Prefer existing section > existing file new subsection > new file (last resort, ask user)
  3. Insert — match surrounding language/style density. New files need frontmatter: tags: [Domain, Topic] + sidebar_position. Available formats: KaTeX, Mermaid, :::tip, ./figures/*.webp
  4. Deduplicate — same concept better info → update; different angle → supplement; truly new → add
  5. Verify — concept not example ✓ no duplicates ✓ matching style ✓ frontmatter if new file ✓

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.
