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 5.1 | $0.00075 | $0.00361 |
| Opus 5 | $0.00037 | $0.00180 |
| Sonnet 5 | $0.00015 | $0.00072 |
| Haiku 4.5 | $0.00007 | $0.00036 |
Grade A, and why
memory-add-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 8d 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
memory-add-note
Preconditions
- Content must be markdown + OKF frontmatter.
- Required frontmatter field:
type(e.g.Note,Runbook,Decision). - Prefer one concept per note (OKF style).
Steps
- If the user gave free text without OKF, wrap it in a valid template (do not invent false facts):
---
type: Note
title: <short title from content>
description: <one line>
tags: [<inferred lowercase tags>]
---
<body>
- Optional:
memory_searchfirst to avoid obvious duplicates. - Call
memory_add_notewith argumentmarkdown= full OKF document. - If updating an existing note:
memory_update_notewithid+ full OKFmarkdown. - To link two known notes:
memory_link_notes(from_id,to_id,kind).
After success
- Report the note
id, title, tags. - Mention rate limit if user is batching many writes.
Failures
- Validation / missing
type→ fix frontmatter and retry once. - 429 → wait; do not loop.
$ARGUMENTS
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.

memory-add-note is a skill published in the GitHub repository MickaelV0/demo-mcp (0 stars, last pushed 1mo ago), licensed MIT. It adds 75 tokens to every session and 361 once invoked, about $0.0004 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 2026-09-01.
