Q&A

Does the skill cache Slack data, and can I control the cache behavior?

Yes, it caches users, channels, and subteams for a default TTL of 3 days. You can adjust the TTL, disable auto‑refresh, or change the cache directory via the environment variables SLACK_SKILL_CACHE_TTL, SLACK_SKILL_CACHE_NO_AUTO, and SLACK_SKILL_CACHE_DIR.

How do I configure authentication for the Slack Skill?

Create a .env file from the provided example and set at least SLACK_BOT_TOKEN with a valid Slack bot token. For search operations you must supply a user token (xoxp); the skill automatically selects the appropriate token based on the subcommand.

Asked by Femi Adebayo · Oct 20, 2025

What Python version and dependencies are required to run the Slack Skill?

The skill requires Python 3.9 or higher and uses only the standard library (urllib); no additional pip packages are needed.

Asked by Ines Zeković · Oct 12, 2025

Can the Slack Skill send messages or add reactions in Slack?

No, the Slack Skill is read‑only; it only accesses Slack Web API subcommands for retrieving data. Actions like sending messages, adding reactions, or marking messages as read must be handled by the calling bot.
