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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It discloses the output content (replica and pod state) and an important edge behavior ('Returns nothing when the tenant has no Kubernetes integration'). It does not explicitly state read-only semantics or pagination behavior, but 'List' implies a read operation and the schema documents paging parameters. This is solid coverage for a list-style tool.

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?

Two sentences with no redundancy. The main purpose is front-loaded, examples and output details follow, and the empty-result edge case is a separate useful sentence. Every word contributes.

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 absence of an output schema and annotations, the description covers the core what, includes output specifics, and notes the no-integration case. It does not describe pagination behavior or result ordering, but those are already inferable from the schema's page/pageSize defaults. For a straightforward read/list tool, this is sufficiently complete.

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?

Schema description coverage is 100%, so the baseline is 3. The description does not add any parameter-specific meaning beyond the schema: tagOrId, page, pageSize, session_id, and context are all already described in the input schema. The phrase 'mapped to an entity' aligns with tagOrId, but adds no new detail.

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 a specific verb ('List') and resource ('Kubernetes resources mapped to an entity') and provides concrete examples ('deployments, statefulsets, cronjobs and the like') along with the included state ('current replica and pod state'). This clearly distinguishes it from sibling tools like AWSGetAwsResources or getCustomDataForEntity, so an agent can identify what this tool does without opening the schema.

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 implies a clear use case: when an entity's Kubernetes resources and their replica/pod state are needed. It does not explicitly name alternatives or state when not to use it, but the resource-specific language makes the context obvious enough for an agent to select it over siblings such as AWSGetAwsResources. The absence of exclusions keeps it from a 5.

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