Compose and send honest agent correspondence on Slack, email and other channels: principal-direct, assistant and bot lanes, the voice axis, review depth, personas, disclosure signatures and send gates. Use for sending on a principal's behalf, message signatures, persona registries or agent voice.
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
# Agent Correspondence How an agent drafts and sends correspondence for a principal honestly: which lane a message belongs in, who narrates it, what its signature discloses, and the gates it passes before it leaves. > **Disclosure should answer the one question the recipient actually cares about: whose words are these? Everything else — how the sausage was made, what approval workflow ran — is internal governance, not disclosure.** ## Binding rules 1. **Every message sits in one lane.** Principal-direct carries no marker; the assistant lane (the principal's words, the agent's hands) carries one authorship signature; the bot lane (the principal's direction, the agent's words) carries the persona's own signature. 2. **The assistant lane requires exact-text ownership.** Words the principal has not made their own go in the bot lane: no signature can honestly say both "these are my words" and "I did not review these words." 3. **The archetype binds the narrator.** An assistant persona writes in the principal's first person; a bot persona says "I" for itself and names the principal in the third person, early. One narrator per message. …

How to install
mdr add synthesisengineering/synthesis-skills/synthesis-agent-correspondence@sha256:fa935929eaa05bfdThe line at the top of this page pins the label v4.1.0, 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.
