Creates Or Updates Project Date

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

Annotations indicate this is a write operation (readOnlyHint=false) but not destructive or idempotent. The description adds that it returns the created object on success (HTTP 201) and provides the API endpoint. However, it does not explain behavior on update (e.g., response code, side effects), which is critical for a create-or-update 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?

The description is four sentences and includes relevant details like the API endpoint. However, the sentence 'Use this to perform the creates or action on Project records' is repetitive and could be removed. It is not as concise as it could be, but not overly verbose.

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 fails to explain critical behavior for a create-or-update tool, such as how update is triggered versus creation, what happens if the date already exists, or response structure for updates. Since there is no output schema, this missing context hampers effective tool usage.

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?

Input schema coverage is 100%, so the schema already documents both parameters. The description only restates that project_id is required, which is already in the schema. It adds no additional meaning or usage context for the 'project_dates' parameter, so it meets the baseline but does not excel.

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 states that the tool associates a project with a project date or updates it, clearly identifying the verb (create/update) and resource (project date). The name and description are specific, distinguishing it from siblings. However, a minor grammatical issue ('creates or action') slightly hinders clarity.

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 gives minimal guidance: 'Use this to perform the creates or action on Project records' is vague. It does not specify when to use this tool versus alternatives, nor does it mention prerequisites or when not to use it. Given the vast sibling list, this lack of guidance is a significant gap.

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