servicenow-atlas: Skill for Claude Code

.agents/skills/embedding-strategies/SKILL.md

embedding-strategies is a skill for Claude Code, Codex from sagar-shirwalkar/servicenow-atlas. It costs 37 tokens per session (4,310 once invoked), scanned A, a copy of embedding-strategies, Apache-2.0.

A guide to choosing and tuning embedding models, which turn text into numeric representations so related documents can be found by meaning. It also covers how to split documents into pieces for search and retrieval-augmented generation (RAG), where an AI answers using a document collection.

In plain words
What is it for?
Use it to compare embedding models, design chunking and preprocessing, support multiple languages, reduce vector size, and adapt semantic search or RAG to a specific subject area.
Why use it?
It helps you choose a suitable model and document-splitting approach instead of relying on search results that miss relevant context or use unnecessary computing resources.

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

embedding-strategies 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 1mo 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.

Origin

This is a copy

89% identical to embedding-strategies — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
