SF Slack

Slack integration — search messages, read threads, browse channel history

What it does

Full Slack integration. Read-only search/thread/history/channel/user/file/canvas plus confirmed send and scheduled-message management. Tools register only after a token resolves (Pi auth store -> SLACK_USER_TOKEN), keeping the system prompt cache stable when Slack is not configured.

Start

Open the extension from its primary command:

/sf-slack

Open its Manager detail or change its package state with:

/sf-pi open sf-slack
/sf-pi enable sf-slack
/sf-pi disable sf-slack

Safety notes

• slack_send requires user confirmation in interactive mode and refuses headless unless SLACK_ALLOW_HEADLESS_SEND=1.
• slack_schedule schedule/delete require user confirmation in interactive mode and refuse headless unless SLACK_ALLOW_HEADLESS_SEND=1.
• Read-only by default; only canvas create/edit, slack_send, and slack_schedule schedule/delete mutate.
• Interactive login uses SF Pi's shared fixed-mask component; Pi alone persists and removes API-key or OAuth-compatible credentials.
• Tokens are never displayed unmasked.
