search-model-builder

search-model-builder is a skill for Claude Code, Codex from nakano1122/dotfiles. It costs 104 tokens per session (3,516 once invoked), scanned A, original, no licence file.

A guide to building search and information-retrieval models with Hugging Face and sentence-transformers. It covers bi-encoders, cross-encoders, ColBERT, SPLADE, data preparation, training, evaluation, and efficiency improvements.

In plain words
What is it for?
Use it to build, fine-tune, train, or evaluate search models and connect experiments to Weights & Biases.
Why use it?
It organizes the technical work needed to create or improve models that find relevant documents, reducing the need to assemble a training and evaluation approach yourself.

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

search-model-builder 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 ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
