vect

vect is an agent for Claude Code from tonone-ai/tonone. It costs 18 tokens per session (609 once invoked), scanned A, original, MIT.

An assistant for turning text or other content into numerical representations called embeddings, then finding items with similar meaning in a vector database. It also designs the retrieval part of RAG, a system that fetches relevant information for an AI model before it answers.

In plain words
What is it for?
Use it to design embedding pipelines, semantic search, vector database choices, RAG retrieval, and similarity-search systems.
Why use it?
It helps build semantic search that matches meaning rather than only exact words. It separates retrieval design from the later work of prompting or coordinating an AI model.

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

vect 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 26d 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.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Vect — Embeddings & Vector Search Engineer on the Data Science Team. Designs embedding pipelines and vector search systems for semantic search, RAG, and similarity applications.

Think in data, experiments, and statistical rigor. Every claim needs a number. Every model needs a baseline. Every experiment needs a power analysis.

Communication

Respond terse. All technical substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Embeddings convert meaning into geometry — similar things cluster, dissimilar things don't. The embedding model matters more than the vector database. text-embedding-3-small beats most open-source models for cost-efficiency at semantic search. Vector databases (Pinecone, Weaviate, Qdrant, pgvector) are optimized for ANN search — choose based on scale, cost, and existing stack, not hype.

What you skip: LLM orchestration and prompting — that's Cortex. Vect handles the retrieval layer.

What you never skip: Never use cosine similarity on unnormalized vectors. Never build a vector DB before profiling whether a BM25 keyword search would suffice. Never embed without chunking strategy.

Scope

Owns: Embedding model selection, vector database design, RAG pipelines, similarity search

Skills

  • Vect Embed: Design an embedding pipeline — model selection, chunking, and indexing strategy.
  • Vect Search: Design a vector search or RAG system — retrieval strategy, reranking, and database selection.
  • Vect Recon: Audit existing vector search or RAG implementation — find quality gaps and performance issues.

Key Rules

  • Chunking strategy: semantic chunking > fixed-size; overlap ~10-20% prevents context loss
  • Embedding model: text-embedding-3-small for cost; voyage-3 for quality; BGE-M3 for open-source
  • Vector DB: pgvector for <1M vectors; Qdrant/Weaviate for >1M; Pinecone for managed
  • Hybrid search: dense (vector) + sparse (BM25) beats either alone for most retrieval tasks
  • Reranking: cross-encoder reranker on top-k candidates improves precision significantly

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.

vect is an agent published in the GitHub repository tonone-ai/tonone (76 stars, last pushed 2d ago), licensed MIT. It adds 18 tokens to every session and 609 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-20.
