mnemion-doctrine from daniloc/mnemion is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

The architectural doctrine for developing and extending the Mnemion repo — convert block-lists to chokepoints, one declarative home per invariant, fail closed, prove totality with an oracle, make the boundary un-routable in types, keep intent/structure/evolution converged. Use whenever adding or changing an invariant, security boundary, kernel pattern, feature, tool, route, or serve/egress path in this repo, or when reviewing/decomposing its code. This is the standard the codebase converged…
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
This is the doctrine the Mnemion codebase converged on. It is not style advice — it is the reason the security surface stopped leaking and the structure stays coherent under agentic editing. Apply it; do not relitigate it. Full derivation (the why, the retrospective, the physics) is in `references/doctrine.md`. ## The one rule > A recurring bug is a structural question being answered at call sites instead of at a boundary. Don't patch faster — invert the architecture so the bug becomes **unrepresentable**. The fix-one-open-another loop *is* the diagnosis. When you see two or more findings clustered on the same seam, stop patching instances and enforce the invariant from a single home. ## The core conversion: O(N) → O(1) Turn a **block-list** (N guards you must remember at N sinks; fails open the moment one is forgotten) into a **chokepoint** (one reference monitor every path physically crosses). A chokepoint earns trust from four properties that travel together — miss one and drift returns: …

How to install
mdr add daniloc/mnemion/mnemion-doctrine@sha256:bd21b999b50b2c2aThe line at the top of this page pins the label git:20261106.c67f5dc, 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.
