Two live Claude Code sessions (Opus 5.5, high effort) given Q09 at the same moment, recorded on one screen: ProtoMap's answers in 50 seconds for $0.40, the baseline's in 6 minutes for $14.44. Sped up where marked.

The prompt
We want to remove the RPC acme.documents.v1.DocumentQueryService/ResolveDocuments. Find every place in every repo that calls it, including indirect calls through helpers, method names built from strings, registries, or reflection, and give file:line and the calling service for each so we can migrate them.
Set up ProtoMap and show me what it can do. ProtoMap maps gRPC services and protobuf messages across repositories, and gives coding agents that graph over MCP. Docs: https://docs.protomap.ai/quickstart/
Tell me what you are about to do before each step that installs something.
1. Check that this computer has git, Docker with Compose 2.23.1 or newer, at least 4 GB of RAM, and 20 GB of disk space. If anything is missing, tell me and stop.
2. Install ProtoMap Server, in a folder outside this repository:
git clone https://github.com/hounddogai/protomap.git
cd protomap
./self-hosted/scripts/install.sh
The installer asks questions. Choose Trial, which runs PostgreSQL locally and logs the CLI in, and keep the default port.
3. Show me the address and the one-time setup key the installer prints. Ask me to open the address, enter the key, and create my organization and owner account. Wait until I say that's done.
4. Scan this repository, from a new shell so the CLI is on the PATH:
protomap scan .
If it has no gRPC services in a supported language, tell me, and offer to scan a public example instead:
git clone https://github.com/GoogleCloudPlatform/microservices-demo.git
protomap scan microservices-demo
5. From the scanned repository's folder, add ProtoMap to yourself as an MCP server:
Claude Code: claude mcp add protomap -- protomap mcp serve
Codex: codex mcp add protomap -- protomap mcp serve
Antigravity: add "protomap": { "command": "protomap", "args": ["mcp", "serve"] } under mcpServers in ~/.gemini/config/mcp_config.json
Others: https://docs.protomap.ai/coding-agents/
Tell me if I need to restart you for it to take effect.
6. Tell me what the scan found, then use ProtoMap's tools to answer one question about my services, such as which services call a method and where. Suggest two more questions I could ask.
