Use when the user asks to inspect API or MCP surfaces.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# API Surface With Anvien

Use this skill for route handlers, MCP/RPC tool handlers, generated contracts, response shape drift, route consumers, and API-impact decisions.

This skill is a workflow gate for API-surface work. It is not a command router. When a concrete Anvien command is needed, choose it directly from the generated Command Selection Guide.

## Command Choices

| Need | CLI | MCP |
|---|---|---|
| Route handlers, consumers, middleware, flows | `anvien api route-map [route] --repo <repo> --json` | `route_map` |
| MCP/tool definitions and linked flows | `anvien api tool-map [tool] --repo <repo> --json` | `tool_map` |
| Response shape drift against consumers | `anvien api shape-check [route] --repo <repo> --json` | `shape_check` |
| Route/API blast radius | `anvien api impact [route] --repo <repo> --json` | `api_impact` |
| Route impact via generic impact | `anvien impact route <route> --repo <repo> --json` | `impact` with `target_type=route` |
| MCP tool impact via generic impact | `anvien impact tool <tool> --repo <repo> --json` | `impact` with `target_type=tool` |

How to install

The exact contents, by fingerprint

mdr add tamnguyendinh/anvien/api-surface@sha256:a59c8a6f7afbcb73

The line at the top of this page pins the label git:20260605.6f76f90, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
