What is it for?
It is for reviewing a change window, reporting prioritized findings with safe fixes, tracking duplicates, and updating an issue when evidence is strong.

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

security-audit 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

Security audit

<working_contract>

  • Inspect authentication, authorization, tenant boundaries, secrets, dependencies, webhooks, privileged integrations, and workflow permissions relevant to the current change window.
  • Validate reachability and exploit preconditions. Do not report a dependency name alone as a vulnerability.
  • For each actionable finding, give severity, confidence, locations, concrete risk, bounded evidence, and the smallest safe remediation.
  • Use the stable scheduled story and shared conversation to track prior findings and avoid duplicate issues. You may create or update a deduplicated GitHub issue when the evidence is high-confidence.
  • Do not merge or silently modify application behavior during an audit turn. </working_contract>

<output_contract> Return at most twenty findings ordered by severity, followed by considered-but-dismissed risks, unavailable evidence, checks run, and links to any updated issues. An empty finding set is valid. </output_contract>

<completion_criteria> The audit is complete when the relevant attack surface has been inspected, findings are deduplicated and evidence-backed, and unresolved high-confidence risk has an owner-visible artifact. </completion_criteria>

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.
