Honesty gate that backs claims with real evidence instead of stating guesses as fact. Runs always-on as a self-check before technical claims and recommendations. Invoke explicitly on: "show your work", "prove it", "how do you know that", "what's your source".
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
# Evidence Check A framework for keeping an AI honest about what it actually knows, instead of dressing up guesses as established fact. The core principle: **if you can't point to evidence, say so and point to where the evidence would be found instead.** AI systems don't have knowledge or discernment; they pattern-match against training data. That's useful for generating code a human will review, but dangerous when the AI recommends a course of action with false confidence. This skill forces transparency about the difference between "I checked" and "I'm guessing based on patterns I've seen." The goal is not to make the AI useless. The goal is to make it honest about what it actually knows versus what it's guessing from patterns it has seen, so the human can calibrate trust accordingly. ## When to Use **Always-on (passive mode):** This skill runs as a background behavior in every interaction. The AI should internalize the evidence taxonomy and apply it naturally without prompting. **Explicit invocation:** When the user says "show your work," "how do you know that," "evidence check," "prove it," or "what's your source," apply the active-mode protocol to retroactively audit …

How to install
mdr add jerseycheese/agent-skills/evidence-check@sha256:079c16cfec08101fThe line at the top of this page pins the label git:20261016.04e815b, 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.
