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

No annotations are provided, so the description carries full behavioral burden. It mentions the listed cron jobs include last run and next run metadata, but does not state that this is a safe read-only operation, whether permissions are required, or whether results are paginated or filtered by anything beyond project and environment.

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 single sentence is appropriately short and front-loaded, with no filler. It is efficient, though it sacrifices some clarity by not using an explicit verb.

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 low-complexity list operation with fully documented parameters and no output schema, the description gives the essential resource and returned metadata. However, with no annotations and no output schema, it could still clarify read-only behavior and scope more explicitly.

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%, with both required parameters (project and env) already documented in the input schema. The description adds no additional parameter meaning, so the baseline score of 3 applies.

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 the resource (cron jobs) and scope (on an environment) and hints at returned fields (last run and next run), but omits an explicit action verb such as 'List'. It is inferable from the tool name and siblings, but not clearly distinguished from cron.runs, which likely lists individual job runs.

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?

There is no explicit when-to-use guidance, no alternatives mentioned, and no exclusion criteria. The only implied usage is that it retrieves cron jobs for a given environment, leaving the agent to infer context from the name and siblings.

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