slack skillA

slack is agent-read markdown (skill) from magnus919/agent-skills: Operate Slack workspaces from a terminal or agent: list channels, read messages, follow threads, search message history, list files, and verify inbound webhook signatures — with a bundled slack-cli script that is read-only by default and gates every send behind a --dry-run/--yes confirmation. Use when an agent needs to read or post Slack data, triage incidents, or answer questions about what was said in a workspace. Do not use for building Slack apps or bots (that is application development) or .

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

Latest version
mdr add magnus919/agent-skills/slack@git:20260804.3256a87
Exact content
mdr add magnus919/agent-skills/slack@sha256:235cff4856f0f952

Pin 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.
