Send one digest-bound message on behalf of a principal, posting to a channel or replying in a bound conversation through a compatible connector, after exact approval and independent provider readback.
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
# Message Send Govern a message sent on behalf of a principal: a channel post or a reply in a bound conversation. The skill never receives a provider token, never lets approved content drift before delivery, and calls a message delivered only after the provider reads it back. ## Composes <!-- Generated from the native execution closure; run pnpm core-skills:composes:generate. --> - `slack#read_thread` ## Runners - `send` (default): plans one channel post, requests approval only at the live post, posts once, and requires independent readback. - `plan`: the provider-neutral authorization step.

It does not post and needs no approval. - `plan_post_exact`: for an operator that has already selected one exact …

How to install
mdr add runxhq/runx/message-send@sha256:3d9a0ef9899a7673The 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.
