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 | $0.00102 | $0.00464 |
| Opus 5 | $0.00051 | $0.00232 |
| Sonnet 5 | $0.00020 | $0.00093 |
| Haiku 4.5 | $0.00010 | $0.00046 |
Grade A, and why
note-taking 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 2d 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
Plain Notes pack — how to work here
The lightest pack: no posture imposed, just write and link.
This skill is pack guidance. The platform
/open-knowledgeskill (read/write/preview/linking/grounding rules) still governs every markdown operation — this layers the notes habit on top.
Folders
notes/— one file per topic, flat. Promote a note into a more structured layout later if you outgrow this.daily/— one journal entry per day (YYYY-MM-DD.md): morning intentions, capture through the day, evening reflection.
Agent behaviors
- Link liberally. The value of this pack is the graph that emerges from links — when a note or entry mentions something worth its own page, link it (stub the page if it doesn't exist yet). OK's link graph builds itself from those edges.
- Daily entries: on the first entry of a day, link to yesterday's entry (its own dated file, e.g.
2026-07-08.md) and pre-fill the date, so the linear journal is also a navigable graph. - The
mood,top3, andgratitudefrontmatter fields on daily entries let you look back across days; fill them when journaling.
Templates
note and daily carry only structure; write freely.
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.

note-taking is a skill published in the GitHub repository inkeep/open-knowledge-skills (6 stars, last pushed 5d ago), licensed MIT. It adds 102 tokens to every session and 464 once invoked, about $0.0005 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.
