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

Skills are the preferred approach for adding new capabilities — they are progressively disclosed into context, more portable, and can be iterated on independently. New non-skill tool registrations (`class ... implements Tool` + `registerTool()`) carry additional costs: 1. **Context overhead** — Each registered tool adds to the system prompt and increases token usage for every conversation. 2. **Maintenance burden** — Tools require ongoing maintenance, testing, and security review. ## What To Do Instead Instead of creating a new tool, consider: 1. **Create a skill** 2. **Use existing tools** - Many capabilities can be achieved by combining existing tools (bash, file operations, network tools) with skill instructions. 3. **External CLI tools** - If you need new functionality, consider whether it can be exposed as a CLI tool that the assistant can invoke via bash. ## If You Have Approval If the core team has approved your new tool: 1. The pre-commit hook will block your commit by default …

How to install
mdr add vellum-ai/vellum-assistant/assistant/src/tools/AGENTS.md@sha256:bcb95da6ad1e9354The line at the top of this page pins the label git:20260709.9bf00f7, 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.
