ground-claims skillA
ground-claims is agent-read markdown (skill) from max-sixty/tend: Ground a public claim in evidence. Use before claiming anything about a tool's behavior, an incident, or code you did not run..
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
# Grounded analysis
- [Source evidence for user-facing claims](#source-evidence-for-user-facing-claims)
- [Verifying external-tool behavior](#verifying-external-tool-behavior)
- [Recurring hallucination shapes](#recurring-hallucination-shapes)
- [Transient incidents vs. durable bugs](#transient-incidents-vs-durable-bugs)
- [Who to ask when you can't do it yourself](#who-to-ask-when-you-cant-do-it-yourself)
## 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@git:20260922.a2c2f60mdr add max-sixty/tend/ground-claims@sha256:36190074164c9151Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
