Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00022 | $0.00210 |
| Opus 5 | $0.00011 | $0.00105 |
| Sonnet 5 | $0.00004 | $0.00042 |
| Haiku 4.5 | $0.00002 | $0.00021 |
Grade A, and why
database-operations 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 4d 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 operations
Use structured database clients or repository data-access APIs instead of parsing database files as text.
Workflow
- Identify the database engine, connection source, migration system, and environment before connecting.
- Inspect schemas, indexes, constraints, and representative row counts with read-only queries first.
- Reproduce query or migration problems against an isolated local database when possible.
- Use query plans and measured timings for performance work.
- Make migrations forward-safe, transactional where supported, and compatible with existing application versions.
- Verify constraints, rollback behavior, query results, and application tests after changes.
Safety
- Treat production and unknown databases as read-only unless the user explicitly authorizes writes.
- Never expose credentials, personal data, or unredacted row contents in chat.
- Back up data before destructive schema changes.
- Bound exploratory queries and avoid full-table exports by default.
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.

database-operations is a skill published in the GitHub repository metaspartan/cybara (25 stars, last pushed today), licensed MIT. It adds 22 tokens to every session and 210 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
