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

The description does not contradict the readOnlyHint=true annotation, which carries the safety profile. It adds some behavioral context by enumerating the return fields, but says nothing about error behavior (e.g., unknown project) or response format. Given annotations already establish the read-only nature, this is a baseline-level contribution.

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?

A single front-loaded sentence with no filler that enumerates the tool's outputs efficiently. It is appropriately short for a simple tool, although it could have used the space to document the parameter.

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 tool (one simple string param, read-only annotation), the description lists the return themes, compensating for the absent output schema. However, it doesn't specify the nature of the returned fields (e.g., type/format of status) or behavior for nonexistent projects, leaving some gaps.

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% and the description never explains what the 'project' parameter holds (name, ID, slug, etc.). The parameter is implicitly referenced in 'Return project status,' but at 0% coverage the description should actively clarify the expected value and does not.

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?

States a specific verb and resource ('Return project status') and lists the concrete return fields (url, image digest, last deploy error). This partly distinguishes it from siblings like get_project and get_logs by naming what it returns, though it does not explicitly name any sibling.

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?

Offers no guidance on when to use this tool versus alternatives such as get_project, get_stats, or get_logs. The intended use case (status checking) is only implied by the name and description, with no exclusions or conditions stated.

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