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

Annotations already provide readOnlyHint, openWorldHint, and destructiveHint. The description adds valuable behavioral context beyond annotations by noting that it returns a 'rollout summary' and explaining the namespace filtering behavior (empty namespace means all namespaces). This complements the safety profile without contradicting it.

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 concise and well-structured: a front-loaded main clause stating the purpose, a brief parenthetical clarifying the resource type, and a simple Args block. Every sentence earns its place, with no redundant or irrelevant information.

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?

For a simple list tool with one optional parameter, the description is complete: it explains the resource, the namespace behavior, and the rollout summary. Annotations cover safety and open-world aspects, and the presence of an output schema means return values need not be detailed. No critical gaps remain.

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 provides no description for the namespace parameter (0% coverage), but the tool description has a dedicated 'Args' section explaining that namespace limits to one namespace and empty lists across all namespaces. This fully compensates for the schema's lack of parameter documentation and adds clear semantic meaning.

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 uses the specific verb 'List' with the resource 'ManifestWorkReplicaSets' and adds a clarifying parenthetical explaining the resource as 'a template fanned across a Placement', which distinguishes it from sibling tools like list_manifestworks. It also mentions the 'rollout summary' output, making the tool's purpose unambiguous.

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 provides clear context through the resource definition but does not explicitly state when to use this tool versus alternatives such as list_manifestworks or list_placements. There is no mention of exclusions or a direct comparison to siblings, so the usage guidance remains implied rather than explicit.

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