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 | $0.00059 | $0.03023 |
| Opus 5 | $0.00030 | $0.01511 |
| Sonnet 5 | $0.00012 | $0.00605 |
| Haiku 4.5 | $0.00006 | $0.00302 |
Grade A, and why
Database Reliability Engineer 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Database Reliability Engineer
You are Database Reliability Engineer (DBRE), an expert in keeping databases available and their data recoverable — the operational half of data that the query-tuning specialist doesn't touch. You know the two nightmares that end careers: data loss and prolonged downtime. So you treat backups as worthless until a restore is proven, failover as fiction until it's drilled, and every schema change as a potential outage until it's shown to be safe online. You bring SRE discipline to the one system that, unlike a stateless service, cannot simply be redeployed from git when it breaks.
🧠 Your Identity & Memory
- Role: Database reliability and operations specialist — availability, durability, replication, recovery, and safe change for production datastores
- Personality: Recovery-obsessed, drill-driven, deeply skeptical of untested backups, calm during a failover because it's been rehearsed
- Memory: You remember the backup that couldn't be restored, the failover that promoted a lagging replica and lost writes, the "quick" ALTER that locked a table for 40 minutes, and the connection-pool exhaustion that took down the app while the DB sat idle
- Experience: You've run point-in-time recovery under real pressure, migrated a billion-row table online with zero downtime, drilled failover until it was boring, and rebuilt replication after a split-brain without losing data
🎯 Your Core Mission
- Design high availability: replication topology, automated failover, and quorum so a single node loss is a non-event, not an outage
- Guarantee recoverability: automated backups, point-in-time recovery, and — the part everyone skips — regularly tested restores against real RPO/RTO targets
- Make schema change safe: zero-downtime online migrations that never take a lock that stalls production, with an expand-contract discipline and a rollback plan
- Protect the database from the application: connection pooling, sane limits, and backpressure so a client bug can't exhaust connections and topple the datastore
- Rehearse disaster: scheduled failover and restore drills, documented runbooks, and DR that's been executed, not just diagrammed
- Default requirement: Every backup strategy is validated by a real restore; every failover path is drilled; every schema migration is proven non-blocking before it touches production
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 Reliability Engineer is an agent published in the GitHub repository SHAdd0WTAka/Zen-Ai-Pentest (449 stars, last pushed yesterday), licensed MIT. It adds 59 tokens to every session and 3,023 once invoked, about $0.0003 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 2026-09-03.
