sign-receipt SKILL.md skillA
sign-receipt from runxhq/runx is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add runxhq/runx/sign-receipt@git:20261023.420f372Pins git:20261023.420f372 in mdr.lock. Pin the fingerprint instead.

Bind an off-runtime action claim to opaque evidence locators in a signed Runx receipt without pretending Runx verified the external action.
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
# Sign Receipt Record a bounded attestation about something that happened outside Runx so a later governed run can cite exactly what was claimed, by whom, on which evidence, and for what reliance scope. The native Runx receipt signature proves the attestation packet was sealed without later modification. It does **not** prove the external action itself happened. That distinction makes this skill useful without turning a signature into a fictional provider verifier. The actual proof remains in the referenced commit, provider object, approval record, transaction, or other evidence system. ## When to use it Use `sign-receipt` when an operator performed a legitimate off-runtime action and downstream automation needs a stable, auditable assertion about it. Examples include a manual console change, an externally approved decision, or a provider operation completed before a native adapter existed. Do not use it to launder an unsupported claim, copy raw evidence into a receipt, or replace a provider readback surface that Runx can actually call. If the external record is available through a governed reader, prefer that stronger evidence path. ## How it works …

How to install
mdr add runxhq/runx/sign-receipt@sha256:3151a69c8e54eb91The line at the top of this page pins the label git:20261023.420f372, 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.
