sun-plugin-slack

A Sun plugin for Slack. It posts one notification per key and updates it in place (with optional Approve / Reject buttons), and sends ephemeral messages only one user sees. It also checks the signing secret on Slack requests forwarded by the kernel (slash commands, messages, @mentions, button clicks, thread replies) and turns them into the task_requested, approval and steer triggers. It talks only to slack.com and reads two secrets, SLACK_BOT_TOKEN and SLACK_SIGNING_SECRET. See mod.yaml; the Slack app setup (scopes, events, interactivity) is in the doc comment at the top of src/main.rs.

Release checklist

1. Bump version in Cargo.toml and mod.yaml (keep them equal), commit.

3. Open a PR to madlabs-tech/sun-ai bumping this plugin's entry in catalog/mods.json (version and permissions).
