Included Skills4

accessskills/access/SKILL.md

Manage Slack channel access control — pairing, allowlist, channel opt-in. Use when approving a pairing code, changing the DM policy, editing the user allowlist, or opting a channel in or out. Trigger with "/slack-channel:access", "pair my slack account", "add user to slack allowlist", or "opt in a slack channel".

configureskills/configure/SKILL.md

Configure Slack channel tokens (bot token + app-level token). Use when writing or rotating the Slack bot and app-level tokens for the slack-channel plugin. Trigger with "/slack-channel:configure", "configure slack tokens", or "set up my slack bot token".

installskills/install/SKILL.md

CCSC lifecycle command center — fresh install walkthrough, health doctor, verify round-trip, auto-repair, Slack app manifest export, reset, tour, and uninstall. Use when installing the Slack channel for the first time, diagnosing or repairing an existing install, exporting a Slack app manifest, or tearing an install down. Trigger with "/slack-channel:install", "install the slack channel", "slack channel doctor", or "uninstall the slack channel".

policyskills/policy/SKILL.md

Author MCP tool-call policy rules without hand-editing access.json. Use when adding, linting, or removing auto_approve/deny/require_approval rules for the Slack channel's policy engine. Trigger with "/slack-channel:policy", "add a policy rule", "lint my slack policy", or "remove a policy rule".
