Use when adding, renaming, or rewriting the description of a skill, command, or agent that will sit beside others in the same registry — the moment you pack a description with the keywords an agent would search for. Keyword coverage makes an entry discoverable; it does not make it selectable. If an installed sibling already claims those words, the router sees two descriptions that both fit and has nothing to choose on. Grep your primary keywords first, then write a reciprocal boundary line…
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
# Name the Boundary Between Siblings **Type:** Open-source — client-agnostic methodology, no project-specific detail. **Created by akbarsha — https://github.com/iamakbarsha1** Distilled from a case where a whole-repo security-audit skill shipped into a library that already held a per-file one — both descriptions matched a bare "security audit" request, and neither file mentioned the other. **Licence:** Released under CC BY 4.0 — share and adapt for any purpose with credit. Full text: `LICENSE` at the repository root. **Feedback & Support:** If a rule here proves wrong or needs sharpening, open an issue on the repository or contact the author at the profile link above. If the problem is the agent not following a rule below rather than the rule itself, that's an execution failure — acknowledge and correct it. ## The core rule Discoverability and selectability are different properties. Packing a description with every word an agent might search for makes the entry findable, and in the same move maximises its overlap with everything already installed — so an entry can satisfy every discoverability rule and still be unpickable, …

How to install
mdr add iamakbarsha1/whetstone/name-the-boundary-between-siblings@sha256:710c7e87948b3708The line at the top of this page pins the label git:20261024.d153cce, 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.
