.claude/agents/database-expert.md

database-expert is an agent for Claude Code from asiflow/hyper-claude-code. It costs 313 tokens per session (6,303 once invoked), scanned A, original, no licence file.

A database and data-architecture review agent for PostgreSQL, Redis, and Firestore. It examines queries, schemas, migrations, connections, caching, data models, and consistency choices.

In plain words
What is it for?
Use it to review schema design, query performance, migration safety, connection pooling, caching strategy, and consistency across these databases.
Why use it?
It helps find database design and operational problems before they cause slow queries, unsafe changes, connection failures, or inconsistent data.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is asiflow/hyper-claude-code's own configuration. It tells Claude Code how to work on hyper-claude-code itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything hyper-claude-code configures →

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-expert 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
