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 | $0.00833 | $0.00833 |
| Opus 5 | $0.00417 | $0.00417 |
| Sonnet 5 | $0.00167 | $0.00167 |
| Haiku 4.5 | $0.00083 | $0.00083 |
Grade A, and why
memarium-plugin CLAUDE.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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
memarium-plugin — contributor / agent guide
Product boundary
This repository is the standalone digest + recall half of memarium. The optional
npm CLI handles cross-device session
transport, aggregation, and resume. Read README.md for installation and the
public workflow. Read versions from package.json, not a status note.
The plugin CLI and hooks do pure I/O; they do not call an LLM. The model's reasoning and memory writing happen in the current session through the skills. Do not add a background inference service as part of a bug fix.

Safety and data contracts
- Shared spool identity is
{tool}:{sessionId}. Preserve IDs during title/path changes; render one.mdper session, not raw JSON/JSONL siblings. - Keep npm and plugin mirrors aligned for shared adapters, types, project identity, writer/index contracts, and manifest/TOC changes. Plugin-only memory and hook logic stays here.
memory/is shared by multiple projects. Never wipe a whole subtree or reset the index as a shortcut for a project-scoped repair. Inspect and back up data before destructive work; do not run a live sync/digest without user approval.- Core/procedural/pinned edits, protected supersession, and trust elevation use
memory-propose. Proposals are local-only and require human review. Never approve your own proposals or silently turn a refusal into another attempt. - Live/partial retro entries leave
sourceSessions: []; those IDs are consumed receipts for the batch digest, not general-purpose session provenance. finalizecan initialize Git, commit allowlisted files, and push when a remote is configured. Never replace its whitelist with repository-wide staging.
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.

memarium-plugin CLAUDE.md is an instructions file published in the GitHub repository june9593/memarium-plugin (1 stars, last pushed 5d ago), licensed MIT. It adds 833 tokens to every session, about $0.0042 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 2026-09-08.
