Prototype one risky assumption within a fixed budget, then keep or discard the result.
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
# Bounded prototype Use a prototype to answer one named question, not to start implementation by a different name. ## Contract Agree on the question, hypothesis, deadline, artifact path, and success signal before writing. Record the source revision. Store artifacts through `scripts/plan-storage.sh`, outside the installed plugin cache. Native read-only plan mode permits a proposal only. Wait for an explicit execution handoff before creating files. Choosing prototype mode does not authorize deployment, provider calls, browser login, repository rewrites, or new permissions. Stop at the deadline. Return observations, a `keep`, `discard`, or `inconclusive` verdict, and the disposition of each artifact. Automatic cleanup may remove only artifacts created by this run after ownership checks. Retain anything the user changed. The completion record contains `question`, `hypothesis`, `deadline`, `artifact_path`, `source_revision`, `observations`, `verdict`, and `disposition`. Adapted from `prototype` in `mattpocock/skills` at commit `3cca18b368ae95cdbdebbff572ccafa662551015` under the MIT License. See `THIRD_PARTY_NOTICES.md`.

How to install
mdr add nyldn/claude-octopus/skill-prototype@sha256:29a9d0c81bdd492dThe line at the top of this page pins the label git:20260906.89d2d35, 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.
