agent-brain-embeddings

A configuration command for choosing the service and model that turn text into numerical representations for meaning-based search.

In plain words
What is it for?
Use it to select providers such as OpenAI, Cohere, Ollama, Gemini, Grok, or Sentence Transformers, and choose a specific model.
Why use it?
It lets semantic search use a provider that fits the project instead of relying on one fixed service.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

agent-brain-embeddings 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 3d 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.

Agent Brain Embeddings Configuration

Purpose

Configures the embedding provider used for vector/semantic search. Embeddings convert text into numerical vectors that enable semantic similarity search.

Usage

/agent-brain:agent-brain-embeddings [provider] [--model <model>]

Parameters

Parameter Required Default Description
provider No - Provider name: openai, cohere, ollama, gemini, grok, sentence-transformers
--model No Provider default Specific model to use

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.

agent-brain-embeddings is a command published in the GitHub repository SpillwaveSolutions/agent-brain (117 stars, last pushed 3d ago), licensed MIT. It adds 14 tokens to every session and 1,461 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
