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 | $0.00535 | $0.00535 |
| Opus 5.5 | $0.00214 | $0.00214 |
| Sonnet 5.5 | $0.00107 | $0.00107 |
| Haiku 4.5 | $0.00053 | $0.00053 |
Grade A, and why
lore 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 2mo 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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lore — Universal AI Memory
You have access to Lore, a persistent memory system via MCP tools. Use it to remember context across sessions and recall relevant knowledge.
When to Use Lore
Session Start
Call recent_activity(hours=24) to load what happened recently.
This gives you grouped context from the last day — decisions, lessons, work done.
During Work
- Before debugging:
recall("describe the problem")— check if this was solved before - After solving something non-obvious:
remember("what you learned", type="lesson") - Key decisions:
remember("decision and reasoning", type="note") - Preferences discovered:
remember("user prefers X", type="preference")
Pre-Compaction (Automatic)
Lore's session accumulator auto-saves snapshots when your context grows large.
You don't need to manually call save_snapshot — but you can if you want to
preserve specific state before a complex transition:
save_snapshot(content="Current state: ...", title="mid-refactor checkpoint")

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.
