Problem

The web_search built-in tool in hero_agent is a stub that always returns:

Web search is not yet configured. Set SEARCH_API_KEY to enable.

There is no actual SEARCH_API_KEY env var handling — the tool always returns this error.

Location

hero_agent/crates/hero_agent_tools/src/web_search.rs — the execute() method returns a hardcoded error.

What's Needed

Implement actual web search using a search API provider. Options:

  • Brave Search API (free tier available)
  • SerpAPI (Google results)
  • Tavily (AI-optimized search)
  • DuckDuckGo (no API key needed, limited)

The implementation should:

  1. Read API key from env var (e.g., HERO_AGENT_SEARCH_API_KEY)
  2. Make HTTP request to search provider
  3. Parse and return top results (title, URL, snippet)
  4. Add the env var to hero_zero/services/hero_agent.toml

Priority

P3 — nice to have, agent works well without it using MCP tools and file/shell operations.
