agent-asearch: Go CLI tool for searching 18 sources in parallel for AI agents, with session-based pagination to reduce token usage

agent-asearch searches simultaneously across web, Hacker News, Reddit, GitHub, YouTube, X/Twitter, and code, plus 18 API backends (Tavily, Exa, Brave, SearXNG, Serper, SerpAPI, Perplexity, You.com, Firecrawl, Parallel.ai, and others); 5 sources work without API keys (Hacker News, Reddit, GitHub, Jina, web auto-fallback).

Returns compact metadata first, then agent reads only selected pages through paginated queries (asearch results read -s SID --seq N --limit M), avoiding context bloat; single Go binary with Cobra as the only dependency.

Session-based workflow stores results locally (~/.asearch/); agent receives session ID and next_commands to continue reading, filtering by source, or closing the session—designed to integrate with terminal agents like Claude Code and Codex.
