SKILL.md

agent-slack

Use agent-slack from $PATH. If it is missing, install it with:

curl -fsSL https://raw.githubusercontent.com/stablyai/agent-slack/main/install.sh | sh

Fallback: npm i -g agent-slack (Node >= 22.5).

Run agent-slack --help or the relevant subcommand help before guessing a command or flag.
If a capability named here is absent from installed help, report version skew instead of guessing. Do not self-update the CLI without explicit authorization.

Safety

Read and search freely.

Perform write actions only when explicitly requested: sends, edits, deletes, reactions, invitations, channel or canvas creation, mark-read operations, scheduling or canceling delivery, uploads, Later state/reminder changes, DM/group-DM creation, and workflow run. Workflow runs can execute downstream actions.

For compose- or review-only requests, return proposed text without invoking Slack, or use message draft create to add a Slack-native draft the user can review and send (nothing is posted). message compose is send-capable; use it only when the user explicitly asks to open the interactive editor. In CI or another noninteractive environment, do not invoke it without separate authorization to send immediately: CI skips the editor and sends supplied text.

With AGENT_SLACK_SAFE_MODE=1 (or the global --safe-mode flag) set, safe mode is enforced at the tool level: message send is redirected to the draft editor and message edit/message delete are blocked. Use it when nothing should post without human review.
