Use when a user asks whether a claim, viral tip, ranking formula or X/Twitter algorithm guide is accurate, supported by code, outdated or misleading.
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
# Check X claims For a new natural-language request, use `x-assistant` first when installed. If this workflow was explicitly selected, delegated with `routed_by: x-assistant`, or installed alone, execute directly; do not route back. Use [the evidence guide](references/knowledge-guide.md). Answer in the user's language. Work from the exact supplied claims; quotation is not agreement. 1. Split the material into independently testable propositions, including numbers, implied universality and practical promises. Retain enough original wording to identify each claim. 2. Retrieve relevant full entries and Q items. Inspect the source's function, caller, audience, code revision and units when they determine the verdict. A source repeating a claim is not evidence for it. 3. Classify each proposition: **supported**, **supported under stated conditions**, **misread/contradicted**, **not established**, or **outdated**. “Not established” does not mean disproven. Reserve “outdated” for evidence of a later change. …

How to install
mdr add alexliyu7352/for-you-skills/x-myth-check@sha256:a2175b785f36f1ceThe line at the top of this page pins the label git:20261031.47c2a4f, 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.
