SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Slack contains the team's ephemeral reasoning, decisions, and discussions that are not captured in databases or tickets; this Skill makes those conversations queryable so you can find context, decisions, and who said what without manually scanning channels.

Core Features & Use Cases

  • Search and Read: Read messages, threads, reactions, timestamps, and sender metadata across public channels and private channels the bot has been invited to.
  • Summarize Decisions & Signals: Extract key points, action items, and sentiment from threads and posts so you can report what the team decided and how they reacted.
  • Operational Controls & Safety: Built-in three-tier permission model (read-only by default, explicit confirmations for configuration and write operations) plus diagnostics for missing channels or stale caches.
  • Cross-reference Workflows: Combine Slack context with other data systems for investigative reports or incident reviews.

Quick Start

Ask the skill to "Summarize recent discussions about migration in #society-testing, list decisions and who committed to actions."
