list_alerts_by_cluster

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It implies a read-only operation but does not disclose pagination, ordering, limits, or whether it returns only active alerts. However, the output schema exists (signal indicates true), which partially compensates for missing behavioral details.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with the purpose. The Args section is somewhat redundant but includes useful examples. It could be more concise by integrating examples into the main sentence, but overall lacks unnecessary verbiage.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (one parameter) and presence of an output schema, the description is fairly complete. However, it misses context on sorting, pagination, error handling, and prerequisites (e.g., cluster must exist). Sibling tools suggest a rich ecosystem, so more guidance would be beneficial.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage for the single parameter 'cluster_name'. The description adds examples ('e.g., 'teddy-prod', 'edge-prod''), providing concrete value beyond the schema's type and title, helping the agent understand valid inputs.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'List alerts filtered by specific cluster', providing a specific verb (List) and resource (alerts) with a distinct filter. It distinguishes from siblings like 'list_alerts' and 'list_active_alerts' by specifying the cluster filter.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool versus alternatives. It does not mention scenarios where other tools (e.g., 'get_alerts_by_state', 'list_alerts') would be more appropriate, nor does it state any prerequisites or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
