Walkerplus event discovery

For a source checkout, use a locally built walkerplus-pp-cli binary with Go 1.26.6 or newer. Catalog installation requires a merged library release. Verify walkerplus-pp-cli --version; if missing, build with go build -o walkerplus-pp-cli ./cmd/walkerplus-pp-cli and make the binary available on PATH. Public Walkerplus HTML is the only runtime source. No credentials, browser, booking, or translation provider is involved. MCP is compiled for stdio only; no HTTP listener is included. When using MCP, inspect truncation metadata and narrow --limit or --select after a bounded result or capture-limit error. CLI JSON error codes remain available; auxiliary diagnostics are separate.

Workflow

1. Resolve the travel location and event category through the catalogs. Accepted codes and source slugs map to Japanese source labels. City codes, source slugs and Japanese city names from areas are accepted with the matching prefecture; for example, --prefecture tokyo --city ar0313104 or --city shinjuku.

2. Discover bounded candidates cheaply. Search reads listings only. Use exact trip dates and inspect coverage before describing completeness.
