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 | $0.05195 | $0.05195 |
| Opus 5.5 | $0.02078 | $0.02078 |
| Sonnet 5.5 | $0.01039 | $0.01039 |
| Haiku 4.5 | $0.00519 | $0.00519 |
Grade B, and why
Lorekeeper CLAUDE.md scanned grade B 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 1mo 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

The opening of the file, as written. The whole thing — 394 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Lorekeeper v2 — Living Agentic Loop
What this is: A personal AI memory MCP server, and simultaneously the first working sample of the Living Agentic Loop — a self-improving agent system that autonomously updates its own CLAUDE.md, skills, and code over time by capturing session learnings and feeding them back in.
The repo serves two purposes:
- The product: MCP server providing
lore_search,lore_remember,lore_insert,lore_update,lore_forget,lore_recommend_links. Replaces the Node.js v1 with Python + LanceDB. - The demonstration: The development process itself is looped. Session learnings are captured → consolidated → applied back to agent config. This repo is the proof of concept.
Data dir: ~/.lorekeeper (LanceDB + SQLite; controlled by LORE_DATA_DIR)
Architecture — Six-Layer (LKPR-105)
Lorekeeper follows a strict 6-layer architecture with unidirectional imports — a layer may import from layers below it, never above.

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.
- 1mo ago First seen · 394 lines · 5,195 tokens per session scan B 7b079fa7da1b
Lorekeeper CLAUDE.md is an instructions file published in the GitHub repository Jessinra/Lorekeeper (5 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 5,195 tokens to every session, about $0.0208 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
