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

Annotations already declare readOnlyHint, idempotentHint, non-destructive, and openWorld behavior, so the bar is lower. The description adds useful behavioral context: it renders the exact request without the credential or the exact task text, and reports problems, while explicitly confirming that it sends and changes nothing.

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 two compact sentences with no filler, and the key safety statement is front-loaded. The first sentence is somewhat dense and duplicates the title, but it remains appropriately sized for the tool.

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?

The description provides helpful return context by saying it renders the exact request or task text plus problems, and annotations cover the safety profile. However, with five parameters at 0% schema description coverage and a nested inputs object, the description leaves important parameter details for the agent to infer.

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 0% across five parameters, including a nested 'inputs' object and required 'key', 'company', and 'environment' fields. The description mentions 'example inputs' and the draft/published choice, but it does not explain the meaning or format of 'key', 'company', 'environment', or how the inputs object is structured.

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 names a specific verb ('Render') and resource ('draft or published action with example inputs'), and clarifies the output context ('exact request ... or exact task text, plus any problems'). It is clear on its own, though it does not explicitly contrast itself with sibling tools such as summer_actions_company_get or summer_actions_company_publish.

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 tool name 'test' and the phrase 'with example inputs' imply it is for previewing/rendering an action, and 'Sends nothing and changes nothing' reassures it is safe. However, the description never states when to use this versus alternatives like company_get or company_publish, nor does it give exclusions or prerequisites.

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