software-search

software-search is a skill for Claude Code, Codex from vasilyu1983/AI-Agents-public. It costs 38 tokens per session (2,899 once invoked), scanned A, original, MIT.

A guide to building application search, from choosing a search engine to indexing data and tuning result relevance. It covers keyword, vector, hybrid, autocomplete, and filtered search.

In plain words
What is it for?
Use it to choose a search engine, build full-text or vector search, add autocomplete and facets, and measure search quality.
Why use it?
It helps users find the right search approach and avoid poorly matched results or unnecessary search infrastructure.

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

software-search 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 20d 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.

Quick Reference

Need Default Deviate when
Full-text search, PostgreSQL already in the stack tsvector/tsquery plus pg_trgm, both on GIN indexes Ranking quality is the gap (ts_rank is not BM25): add a BM25 extension if the host allows it and its licence fits. Facets with counts, typo tolerance, merchandising, or latency at scale: move to a dedicated engine
Dedicated engine Managed service when no one owns search-cluster operations Self-host when data residency, cost at volume, or query control requires it and someone owns the cluster
Embedded or client-side search Embedded index (such as SQLite FTS5) or a static client-side index The corpus or its update rate outgrows a shipped index
Semantic search Vector retrieval as a complement to lexical recall, in the existing database first when it supports vectors Judged-query evidence shows the in-database option misses the latency or recall target
Hybrid search Keyword + vector, merged with reciprocal rank fusion Native fusion is missing from the edition or licence tier you will run: fuse in the application
Autocomplete Prefix matching, search-as-you-type index, debounced queries
Faceted search Aggregation queries, filter counts, hierarchical facets
Search analytics Click-through rate, zero-result queries, query refinement patterns
Search UI The chosen engine's client UI library, if it has one Custom components when the library cannot express the UX

Lookup step before naming an engine. Engine capabilities, licences, and managed-service limits change from release to release, so shortlist by the criteria above, then check each candidate's current documentation and licence. Start from data/sources.json; the capability matrix in references/engine-and-relevance.md is a starting point, not current fact.

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.
