- New tool: maps_static_map returns PNG map as MCP image content
- Supports markers, paths, 4 map types (roadmap/satellite/terrain/hybrid)
- Auto-fit zoom when markers/path provided without explicit zoom
- URL length validation (16,384 char limit)
- All 9 files synced per Tool Change Checklist (14 → 15 tools)
- Added Visualization category to SKILL.md Tool Map
- Added chaining patterns: search→map, directions→map

Subject: [PATCH 2/5] feat: add batch-geocode CLI + MCP prompt templates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Batch Geocode:
- New `batch-geocode` CLI subcommand: reads addresses from file, geocodes in parallel
- Configurable concurrency (default 20, max 50)
- Supports stdin input (`-i -`) and file output (`-o results.json`)

MCP Prompt Templates:
- 3 geo prompts: travel-planner, neighborhood-scout, route-optimizer
- Registered via McpServer.registerPrompt() — auto-discovers prompts capability
- Each prompt returns structured messages teaching AI how to chain geo tools
- Available as `/` commands in Claude Desktop and compatible clients

Subject: [PATCH 4/5] test: add API call tests for air_quality, static_map,
 batch-geocode

- Air quality: MCP tool call + exec mode (Tokyo AQI)
- Static map: MCP tool call (image content type, PNG, base64) + exec mode
- Batch geocode: CLI subcommand with temp file (2 addresses)
- Total: 118 assertions (was ~100)
