install-embeddings

An installer for RTFM's embeddings add-on, which downloads a small language model used to compare the meaning of text rather than only matching exact words.

In plain words
What is it for?
It is for installing the embeddings extra in an isolated Python environment so RTFM can use semantic or hybrid search.
Why use it?
It enables semantic and hybrid search when ordinary keyword search is not enough to find related information.

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

install-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 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 it actually says

Install RTFM's embeddings extra by running this command via the Bash tool:

"${CLAUDE_PLUGIN_ROOT}/bin/rtfm-install-extras" embeddings

After it completes, tell the user to restart Claude Code so the MCP server picks up the new extras venv. Then rtfm_search with search_type="semantic" or "hybrid" will work.

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.

install-embeddings is a skill published in the GitHub repository roomi-fields/rtfm (24 stars, last pushed 2d ago), licensed MIT. It adds 39 tokens to every session and 125 once invoked, about $0.0002 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.
