evidence-based-citations skillA
evidence-based-citations is agent-read markdown (skill) from openhands/extensions: Back factual claims and field values with official, verifiable sources. Use when the user asks to fill fields, answer questions, or make claims that must be supported by an exact quote and an official link..
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.
What the file says
The user wants every field value or factual claim you produce in the current response to be backed by an official, verifiable source. Apply this skill to the response that triggered it; do not assume it stays active for the rest of the conversation unless the user clearly asks for it to. ## Output format For each field or claim, respond with exactly these four labeled lines: - **Field**: the field name (or a short description of the claim) - **Value**: the value you are assigning (or the claim itself) - **Quote**: the exact verbatim text from the source that supports the value - **Source**: the official URL where the quote can be found When there are multiple fields, repeat the block once per field. Keep blocks separated by a blank line. ## Source selection rules 1. Prefer primary sources, in this order: - Official product / project documentation - Standards documents (RFCs, W3C specs, ISO standards) - Official API references - Source code in the project's own repository 2. Accept secondary sources (blog posts, Stack Overflow, forum threads, news articles, third-party tutorials) only as a last resort, and clearly label them as such in **Source**. …

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
