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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00014 | $0.00271 |
| Opus 5.5 | $0.00006 | $0.00108 |
| Sonnet 5.5 | $0.00003 | $0.00054 |
| Haiku 4.5 | $0.00001 | $0.00027 |
Grade A, and why
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 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.
What it actually says
Notes Skill
Use Notes for durable facts, decisions, preferences, and project context that should help future sessions. Notes are Markdown files in knowledge/; docs/ remains read-only reference material.
Tools
list_notes: browse folders or search by text.read_note: read one Note and receive its current revision.create_note: create a Note from a title, optional body, and optional folder.update_note: change a title or body, or append content, using the current revision.
Safe update rule
Before every update, read it before updating and pass its returned revision as expectedRevision. If the revision conflicts, read the Note again, reconcile the newer content, and retry; never overwrite concurrent changes blindly.
Search before creating so one topic does not fragment across duplicate Notes. Prefer updating an existing canonical Note when it already owns the subject.
Writing guidance
- Keep entries concise, factual, and useful beyond the current task.
- Record decisions with their context and date when timing matters.
- Correct stale facts instead of appending contradictory versions.
- Never store credentials, tokens, or other secrets in a Note.
- Do not use Notes for temporary scratch output or session transcripts.
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.

notes is a skill published in the GitHub repository hristo2612/jinn (325 stars, last pushed 27d ago), licensed MIT. It adds 14 tokens to every session and 271 once invoked, about $0.0001 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 2026-08-30.
