Create Basecamp Check-in Answer

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

Annotations indicate it's a write operation (readOnlyHint=false) but not destructive or idempotent. The description adds that content must be HTML, which is a useful behavioral constraint. However, it does not explain side effects (e.g., whether it triggers notifications) or any rate limits, so transparency is adequate but not enriched beyond annotations.

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 redundant words. The first sentence states the purpose, the second provides a critical formatting constraint. Every sentence is necessary and efficiently written.

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 tool's simplicity (3 required params, no output schema), the description covers the core action and a key constraint. However, it omits details about the return value or confirmation, and does not mention how the answer relates to the check-in question or whether it is immediately visible. This is adequate but not 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 coverage is 100%, so the schema already describes each parameter. The description adds no new parameter details beyond stating that content must be HTML, which is already in the schema's content description. Thus, it meets the baseline but adds no extra value for parameters.

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 clearly states the tool creates a new answer for a check-in question, using a specific verb and resource, and distinguishes it from sibling tools like basecamp_create_comment or basecamp_create_message by mentioning 'check-in answer'. The requirement that content must be HTML is also specified.

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?

No guidance on when to use this tool versus alternatives (e.g., basecamp_get_answer for retrieving, or other create tools). It does not mention prerequisites, such as needing to have or know the question_id, or whether the check-in must be active.

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