get_promql_series
AI agents call get_promql_series to retrieve information from Awslabs Valkey without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix and 'promql_series' suffix strongly indicate this tool retrieves or queries monitoring/metrics data without modification. In the absence of destructive keywords (delete, drop, purge) or side effects (create, update, execute), this is classified as Read. Confidence is moderate (0.7) rather than high because the description is empty, leaving some uncertainty about actual implementation details.
From the tool's definition Tool name 'get_promql_series' indicates querying/retrieving time series data via PrometheusQL (promql), with 'get' prefix suggesting read-only data retrieval. No description provided to confirm exact behavior.
