astra-vector-backend

astra-vector-backend is a skill for Claude Code, Codex from erichare/skillroute. It costs 27 tokens per session (121 once invoked), scanned A, original, MIT.

A backend design for Astra DB, a cloud database that can store data and search by meaning, using its data API and vector indexes.

In plain words
What is it for?
Use it to build Astra DB vector-search backends, check retrieved data and metadata filters, and connect them to LangChain-compatible stores.
Why use it?
It provides a consistent way to add meaning-based search, metadata filters, and retrieval to an application without tying the application to one storage layout.

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

astra-vector-backend 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 6d 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

Astra Vector Backend

Use this skill for Astra DB Data API integrations, vector indexes, retrieval metadata, and LangChain-compatible vector store adapters.

When to Use

  • Add a vector backend behind a provider-neutral interface.
  • Store skill routing metadata in Astra DB.
  • Validate retrieval payloads and metadata filtering behavior.
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.
