fandhe-vector-db

fandhe-vector-db is a skill for Claude Code from Fandhe-AI/agent-reference-skills. It costs 122 tokens per session (2,485 once invoked), scanned A, original, no licence file.

A local-first vector database written in Rust that can be used through PostgreSQL’s network protocol. It supports vector and text search, ranking combinations, stored data, tenant separation, and access-control rules.

In plain words
What is it for?
Use it for similarity search, BM25 text search, hybrid search, reranking, and multi-tenant data access. It is also for software that needs its documented query, persistence, and error interfaces.
Why use it?
It provides a way to store and search data using vectors and text while keeping the database local. PostgreSQL protocol compatibility can make it easier for tools that already speak PostgreSQL to connect.

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-vector-db 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 2d 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 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.
