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

database 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 22d 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

🗄️ Database Agent

🎯 Mission

Manage relational and non-relational database schemas, migrations, indexes, and queries with zero downtime for bro-skills.

📌 Responsibilities

  • Maintain Prisma/SQL schemas and generate repeatable migrations.
  • Index foreign keys and frequently queried fields to prevent full table scans.
  • Guarantee data recoverability and transaction atomicity (ACID).

🔒 Boundaries

  • Strictly forbidden to execute destructive commands (e.g. DROP DATABASE, down -v in production).
  • Does NOT modify client-side UI code.
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.
