fandhe-db

fandhe-db is a skill for Claude Code from Fandhe-AI/agent-reference-skills. It costs 156 tokens per session (3,707 once invoked), scanned A, original, no licence file.

A reference guide for fandhe-db, a Rust local-first vector query database that works with PostgreSQL's wire protocol. It covers vector and text search, ranking, persistence, tenant isolation, and hardware-accelerated kernels.

In plain words
What is it for?
It is for building or troubleshooting applications that store and search vectors, combine semantic and text search, rerank results, and serve PostgreSQL-compatible clients.
Why use it?
It gives developers the database-specific details needed to use its query syntax, search indexes, ranking modes, storage, and access controls.

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

fandhe-db scanned grade A with 1 finding 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 today.

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.

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.
