Synthesis Slack Sync

A protocol for syncing Slack channels and threads to local transcript files using Slack MCP. Designed for AI-assisted workflows where an agent reads Slack on behalf of a user, saves transcripts locally, and updates a daily action plan.

This skill provides the protocol — the sync methodology, thread re-reading discipline, transcript format, and action plan update rules. A per-project config file provides the specifics: which channels, which paths, which DMs. Prefer .agents/slack-sync.yaml; existing .claude/slack-sync.yaml configs remain supported.

Version history and the incidents behind each rule: references/version-history.md. Transcript and permalink formats: references/transcript-formats.md. Draft templates: templates/draft-block.md and templates/sent-marker.md.

Configuration

Create .agents/slack-sync.yaml in each project that uses this skill. Existing .claude/slack-sync.yaml configs are valid compatibility fallbacks.
