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 | $0.00828 | $0.00828 |
| Opus 5.5 | $0.00331 | $0.00331 |
| Sonnet 5.5 | $0.00166 | $0.00166 |
| Haiku 4.5 | $0.00083 | $0.00083 |
Grade A, and why
M3E structure.md 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.
How it starts
The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Structure
Organization Philosophy
M3E separates product source, stable release output, strategy/spec documents, operations rules, protocols, and task artifacts. New work should land in the smallest directory boundary that already owns the behavior.
Directory Patterns
Active Product Source
Location: beta/
Active development target. Contains TypeScript source, prompts, tests, build config, local server, browser viewer, and beta-specific policy.
Stable Release Surface
Location: final/
Stable distribution target. Do not implement new product behavior directly here; validated beta changes are migrated into final.
Product and Architecture Documents
Location: docs/
Long-lived planning, specification, architecture, operations, ADR, task, and daily documents. Design/spec/architecture prose is Japanese by default.
Runtime Protocols
Location: docs/protocols/
Operational protocols for worker behavior, map writes, scope operations, handoff packets, and map-manager routing.
Agent Skills
Location: .agents/skills/
Project-local skill instructions for M3E map, map manager, worker, notation, and bridge tasks. Do not duplicate detailed behavior elsewhere when a local skill is the route.
Scripts
Location: scripts/
Operational helpers, launch scripts, worktree lifecycle helpers, and platform-specific runtime setup.
Backlog and Ideas
Location: backlog/, docs/ideas/
backlog/ is the inbox for unclassified captures and pending material; docs/ideas/ is the canonical home for classified ideas. Promote stable decisions into docs/06_Operations/Decision_Pool.md, docs/03_Spec/, docs/04_Architecture/, or ADRs as appropriate.
Beta Source Patterns
Shared Types
Location: beta/src/shared/
Shared TypeScript contracts used across Node and browser code.
Node Runtime
Location: beta/src/node/
Local server, SQLite persistence, sync/import/export, AI proxy, audit, backup, graph runtime, and CLI utilities.
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.

M3E structure.md is an instructions file published in the GitHub repository akaghef/M3E (11 stars, last pushed 5d ago), licensed MIT. It adds 828 tokens to every session, about $0.0033 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.
