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.

Security

Grade A, and why

pollux 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 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.

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 it actually says

CLAUDE.md

projectmem (MANDATORY)

Use projectmem as this project's persistent engineering memory.

At session start call get_instructions(), then get_summary(), then get_project_map() when structure matters, and get_plan() for current intent. Call precheck_file(path) before modifying a file.

Log bugs before fixing, record every attempt and its outcome, close issues only after verification, and record decisions/gotchas with their reasons and evidence.

Do not hand-edit events.jsonl, summary.md, or generated issues/*.md. PROJECT_MAP.md and plan.md are maintained directly when current structure or intent changes. Confirm the session is recorded with get_summary() before exit.

Changes

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.
