synthesis-slack-sync skillA

synthesis-slack-sync is agent-read markdown (skill) from synthesisengineering/synthesis-skills: Slack channel sync protocol for AI-assisted workflows. Reads channels and threads via Slack MCP, saves to local transcript files in workspace-scoped repos, and updates person-scoped daily action plans. Handles mid-day re-syncs with thread staleness detection. Use when asked to: slack sync, sync from slack, check slack, read channels, sync messages, sync transcripts, what's new on slack..

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 synthesisengineering/synthesis-skills/synthesis-slack-sync@v3.10.0
Exact content

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.
