Ground a public claim in evidence. Use before claiming anything about a tool's behavior, an incident, or code you did not run.
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.

# Grounded analysis

- [Verifying external-tool behavior](#verifying-external-tool-behavior)
- [Recurring hallucination shapes](#recurring-hallucination-shapes)

## Source evidence for user-facing claims
Before posting any specific claim — a configuration snippet, command syntax,
variable name, or API behavior — find the **source text** that confirms it:
documentation, help output, test expectations, or the code implementing the
public interface. Internal implementation code shows what exists internally,
not how it's exposed; read the docs or user-facing layer too.
<example>
<bad reason="Read Rust code showing a 'target' variable and invented $WT_TARGET">
Bad: Saw `extra_vars.push(("target", target_branch))` in Rust source → posted a hook example using `$WT_TARGET` (an environment variable that doesn't exist — hooks use `{{ target }}` Jinja templates).
</bad>

How to install
mdr add max-sixty/tend/ground-claims@sha256:7c80948c65692779The line at the top of this page pins the label git:20261027.b6181d7, 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.
