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 | $0.00015 | $0.00472 |
| Opus 5 | $0.00008 | $0.00236 |
| Sonnet 5 | $0.00003 | $0.00094 |
| Haiku 4.5 | $0.00002 | $0.00047 |
Grade A, and why
create-note 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 yesterday.
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
Create Note
Create a new atomic note in the Brain vault.
Arguments
$ARGUMENTS - The note title or topic
Step 1: Generate Note Metadata
Create the note with proper YAML frontmatter:
---
created: [today's date YYYY-MM-DD]
updated: [today's date YYYY-MM-DD]
created_by: claude
updated_by: claude
tags: []
---
Step 2: Determine Note Type
Based on the content/title, place the note in:
- Raw idea/capture →
Brain/00-Inbox/Quick Captures/ - External source material →
Brain/01-Sources/ - Processed insight →
Brain/02-Permanent/ - Index/overview →
Brain/03-MOCs/ - Article/content →
Brain/04-Output/Articles/
Default to Brain/02-Permanent/ for most notes.
Step 3: Check for Duplicates
Search existing notes for similar titles or content:
Grep for the main keywords in Brain/02-Permanent/
If similar notes exist:
- Show user the potential duplicates
- Ask if they want to proceed or link to existing
Step 4: Write the Note
Create the file with kebab-case filename:
- Title: "My Great Insight" →
my-great-insight.md
Structure:
---
[frontmatter]
---
# [Title]
[Main content - atomic, single idea]
## Key Points
- Point 1
- Point 2
## Connections
- [[Related Note]] - relationship description
Step 5: Update Changelog
Append to Brain/CHANGELOG.md:
## [Today's Date]
- Created: [note-title] in 02-Permanent/
Step 6: Report
Tell user:
- Note created at [path]
- Suggest running

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.

create-note is a skill published in the GitHub repository Abilityai/abilities (11 stars, last pushed 14d ago), licensed MIT. It adds 15 tokens to every session and 472 once invoked, about $0.0001 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 2026-08-30.
