Use when a user wants to design or plan how an AI agent gets and uses email — giving an agent its own inbox, deciding between owner-managed vs self-registered provisioning, building a receive/triage/reply loop, sending notifications with human approval, or choosing which credential/surface to use — especially when they're unsure how to architect this, even if Sendmux isn't named.

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.

mdr add sendmux/skills/sendmux-email-for-agents@sha256:8b68dc2481550391The line at the top of this page pins the label v1.0, 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.
