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 | $0.00041 | $0.00540 |
| Opus 5.5 | $0.00016 | $0.00216 |
| Sonnet 5.5 | $0.00008 | $0.00108 |
| Haiku 4.5 | $0.00004 | $0.00054 |
Grade A, and why
mindmap-notation 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 5d 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
Mindmap Notation Skill
Canonical path forms
- Standard instruction path:
M:(開発)> SYSTEM > DEV >> scratch - Scope transition:
M:(開発)> A > B >> C - Legacy/API compatibility path:
Map:Root/SYSTEM/DEV/scratch - ID reference:
#n_1234567890_abc123 - Current scope:
@scope
> and >> are official. / is non-official legacy/API/external compatibility only. \ is filesystem only.
Operation shorthand
- Add:
+ "New node" under M:(開発)> ... > parent - Delete:
- M:(開発)> ... > node - Move:
M:(開発)> ... > node -> M:(開発)> ... > new parent - Rename:
M:(開発)> ... > old := "new" - Attribute:
M:(開発)> ... > node [status: done]
Required distinctions
edge= parent-child tree relationGraphLink= non-tree node relation- node-level
link= URL/attribute alias= reference window to canonical entity
MF / WMF handling
When MF-* / WMF-* labels are used, preserve them as stable human-facing identifiers unless the task explicitly asks to renumber or rename. Do not infer structural ownership from identifier prefixes alone; resolve actual map path/scope first.
MF-H
MF-H is the M3E human-facing name for a Markdown heading tree fragment.
Use it when # heading depth is intentionally used as tree depth.
Relative MF-H fragment semantics:
# Child
## Grandchild
#means direct child of the resolved active node or target parent.##means child of the preceding#node.- Deeper headings continue the same relative tree rule.
- The active node itself is not repeated unless the request explicitly asks for a full subtree.
MF / WMF / Mermaid are interchange, render, or request formats. They are not M3E storage. Resolve the canonical M3E target before interpreting them as a writeback request.
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.

mindmap-notation is a skill published in the GitHub repository akaghef/M3E (11 stars, last pushed 5d ago), licensed MIT. It adds 41 tokens to every session and 540 once invoked, about $0.0002 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 2026-10-02.
