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 B, and why

boot 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.

What it actually says

Load Memory

Learned Rules

!cat .claude/memory/learned-rules.md 2>/dev/null || echo "No learned rules yet"

Last Session Score

!tail -1 .claude/memory/sessions.jsonl 2>/dev/null || echo "No session history"

Unresolved Violations

!tail -5 .claude/memory/violations.jsonl 2>/dev/null || echo "No violations logged"

Instructions

  1. Read every rule in learned-rules.md. For each rule that has a verify: line, run the check NOW.
  2. Report results:
    • All pass → "All rules verified. Ready to work."
    • Any fail → list violations with file:line and specific fix.
  3. Check session trend: if sessions.jsonl has 5+ entries, report one-line trend (corrections increasing/decreasing, common violations).
  4. You are now primed. Proceed with the user's task.

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.
