add_agenda_item

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

With no annotations present, the description carries the full burden of behavioral disclosure. It only states an action and target, but does not mention side effects (e.g., whether the item is appended or replaces), ordering constraints, permission requirements, or reversibility. For a mutating tool, this is a significant lack of transparency.

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 a single, clear sentence with no superfluous words. It is concise and front-loaded, though it is under-specified in content. This dimension rewards efficient phrasing, so it earns a high score despite the lack of detail.

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 tool with six parameters, no output schema, and very sparse schema descriptions, the description is grossly inadequate. It does not explain what an agenda item is, the role of each parameter, or any implied constraints. An agent would not know how to correctly populate the fields, making the tool difficult to use correctly.

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 only 17% (only the estimate parameter has a brief description). The description itself provides zero explanation of parameters like type, week, project, or notes, nor does it clarify the meaning of the 'type' enum. Given this low coverage, the description should compensate, but it fails entirely to clarify any parameter semantics.

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 action (add) and the resource (weekly agenda board), making the tool's purpose unambiguous. It does not explicitly distinguish it from update_agenda_item or delete_agenda_item, but 'add' is a distinct operation and the target is specific. A minor gap is not naming alternatives when siblings exist.

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 is provided on when to use this tool versus the sibling tools such as update_agenda_item or get_agenda. There is no mention of prerequisites, sequencing, or scenarios where this tool is preferred. The description leaves usage entirely to inference.

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