AI agents call get_subreddit_info to retrieve information from Reddirect without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a pure query operation that fetches and displays public subreddit information. It has no side effects, does not modify data, and does not trigger external operations beyond simple retrieval. The blast radius of misuse is minimal—an agent could learn subreddit details but cannot harm users, data, or systems.
From the tool's definition Tool retrieves subreddit metadata: 'description, rules, subscriber count, and whether it is NSFW' with no modification capability indicated.

Yes. Add a rate_limit block to the get_subreddit_info rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
