slack skillA
slack is agent-read markdown (skill) from bitterbot-ai/bitterbot-desktop: Use when you need to control Slack from Bitterbot via the slack tool, including reacting to messages or pinning/unpinning items in Slack channels or DMs..
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.
How to install
mdr add bitterbot-ai/bitterbot-desktop/slack@git:20260328.33f9833mdr add bitterbot-ai/bitterbot-desktop/slack@sha256:75fea7e7987fec59Pin 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.
