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 | $0.00464 | $0.00464 |
| Opus 5 | $0.00232 | $0.00232 |
| Sonnet 5 | $0.00093 | $0.00093 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade C, and why
agent-logbook CLAUDE.md scanned grade C with 1 finding 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 9d 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.

Memory protocol
This project has a long-term memory served by the memory MCP server. The context window is working memory only; durable knowledge lives in the memory store. Follow this protocol:
-
At the start of every task, call
recall(query)with a few keywords describing the task, before doing any work. Ifopen_items_count> 0 and you are planning, also calllist_open(). -
After completing any work block that produced a decision, a durable fact, a new task, or an open question, call
remember(type, content, entity). Rules for what you store:contentis ONE or TWO self-contained sentences, declarative, understandable without any conversation context. Distill — never paste transcript or code blocks.entityis a short stable slug for the subject (e.g.auth,db-choice,deploy-pipeline). Reuse existing entity slugs when the subject is the same.- Types:
decision(choices made and why),fact(durable truths about the project),task(work to do later),question(unresolved),note(everything else). Prefer decision/fact over note.
-
If
rememberreturns a conflict, never force silently. If the new information clearly replaces the old, callsupersede(old_id, new_content). If it is genuinely ambiguous, ask the user which stands. Useforce=trueonly when both memories are simultaneously true. -
When the user says "actually..." or changes a prior decision, find the old memory (recall it if needed) and
supersedeit — do not create a parallel memory. -
When a task or question is resolved, call
set_status(id, "done"). -
Do not store: secrets, API keys, credentials, personal data, transient debugging state, or anything the user asks to keep out of memory.
-
Memory is the source of truth for past decisions. If your recollection from context conflicts with a recalled memory, trust the memory or ask.
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.
