Investigate, implement and verify code changes directly in a repository using Leon's file, search and shell tools.
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
# Coding Use Leon's existing agent loop and tools to complete coding tasks directly. Respect the owner's requested scope: analysis is not authorization to edit, commit, push or publish. Delegate only when the owner asks or has an applicable preference. For requested delegation, use the owner's preferred available agent and interface. Pass the repository, task, applicable instructions and authorized scope. Inspect and verify the actual result; submitting a prompt is not completion. If delegation is unavailable, explain briefly and continue directly within the authorized scope. ## Repository and instructions 1. Establish the exact workspace and working directory from the request and live observations. Read relevant manifests and nearby implementations; use existing helpers before adding abstractions. 2. Before editing, discover and read applicable `AGENTS.md` files from the repository root through each target directory. Deeper instructions apply only within their directory and take precedence over broader project rules. For a non-Git workspace, use the owner-selected workspace boundary; do not inherit unrelated parent-directory instructions. …

How to install
mdr add leon-ai/leon/coding@sha256:00871bcf5be0f1f8The line at the top of this page pins the label v1.0.0, 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.
