Probe a Wikipedia article at multiple time points and return quality metrics.
AI agents call probe_article_over_time to retrieve information from Wikicitation without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes historical data about Wikipedia articles (quality metrics over time). It has no side effects, does not modify data, does not execute arbitrary code, and does not delete or move resources. The action is read-only: querying article state and computing metrics. Low severity reflects minimal blast radius even if misused — the worst outcome is retrieving misleading quality data.
From the tool's definition Tool description states it 'probes a Wikipedia article at multiple time points and return[s] quality metrics' — purely observational/analytical operations with no modification or execution of external code.

probe_article_over_time is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the probe_article_over_time 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.
