README

web-search

LLM-neutral web search skill for AI coding agents (pi, hermes-agent, openclaw, opencode, claude-code, etc.).

Instead of hard-coding a single search provider into every agent, this skill lets the agent invoke a single command (`scripts/web-search`) that fans out across **12 search providers**, dumps raw + normalized results to a temp directory, and prints a path the agent can pipe through `rg`, `jq`, or any other tool.

**Zero config out of the box** — DuckDuckGo and MWMBL accept anonymous calls. Add API keys for richer providers (Tavily, Brave, Perplexity, Anthropic, OpenAI, etc.) when you want them.

Why a skill, not a library?

Agent harnesses already have a way to load skills on demand. Embedding web search as a skill means:

No fixed context cost — the skill loads only when the agent needs to search.
No vendor lock-in — swap providers per call, or fan out across many in parallel.
No SDK churn — pure Python 3 stdlib + curl. Works wherever Python 3 runs.
Pipeline-native — results live as JSON files on disk so rg, jq, grep, python -c all just work.
