rubber-duck skillA

rubber-duck is agent-read markdown (skill) from the-artificer-of-ciphers-llc/skills-from-the-artificer: Rubber duck debugging session. Use when the user is stuck on a bug and can't find the cause, says "I don't understand why this isn't working", "help me think through this", "talk me through this bug", or "rubber duck". Also use when a developer has been debugging for >20 minutes without progress — the duck is most valuable before frustration distorts thinking. Triggers on: "stuck", "can't figure out", "doesn't make sense", "walk me through", "help me think", "rubber duck", "explain why"..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
