Test report

Verdict: Works with setup
Score: 8.8/10
Tested: Jul 16, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 8e72546

Well-engineered 4-step router (triage -> search -> deep-iterate -> report) with a hard 3-pass budget and 'never fabricate, cite every claim' rule enforced at the synthesis step -- but it hard-requires the Exa MCP server (mcp__exa__*) which isn't bundled or available in this environment, so the routing/formatting logic could only be evaluated on paper, not live-executed.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What WebSearch (Exa Power Search) does

Parses flags and query intent to route a search through the right Exa MCP tool and formats a cited report per mode -- code snippets for --code, side-by-side tables for --compare, gap-driven multi-pass research for --deep. Trigger it for web search, doc lookup, error debugging, or comparing options; it requires the Exa MCP server (with its own API key) to actually run.
