What is cory-mem CLAUDE.md?

A set of project instructions for cory-mem, a personal memory system for AI applications with short-term and persistent memory.

It helps maintain the system's memory manager, search engine, embedding providers, session handling, and immutable data models.

It gives the coding assistant the project's architecture and rules, including how memory types, search, embeddings, and immutable data structures fit together.

Token cost

What it costs to keep this loaded

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	$0.01374	$0.01374
Opus 5.5	$0.00550	$0.00550
Sonnet 5.5	$0.00275	$0.00275
Haiku 4.5	$0.00137	$0.00137

Security

Grade A, and why

cory-mem 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.

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.
