create-channel-section

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It notes that creation costs 50 quota units, which is a useful constraint, but it does not disclose permissions, side effects (e.g., reordering of sections), or response format. This is a minimal but non-empty disclosure.

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 sentence with no redundant wording. It is front-loaded with the action and includes one contextual clarification ('homepage shelf') plus the cost. Every word earns its place.

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 complete parameter schema and the straightforward nature of a create operation, the description is sufficient for basic invocation. It does not explain return values, but the absence of an output schema and the CRUD simplicity make this acceptable. The quota cost adds valuable context for decision-making.

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%, with each parameter having a description. The tool description adds no parameter-level detail beyond the schema, so it does not raise the baseline. The baseline of 3 is appropriate since the schema already documents all fields.

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 a specific action ('Create') on a specific resource ('channel section') with an explanatory parenthetical ('homepage shelf'). This unambiguously distinguishes it from sibling tools like list-channel-sections, update-channel-section, and delete-channel-section.

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 phrase 'Create a new channel section' gives clear context for when to use the tool: to add a new section. It does not explicitly mention when not to use it or name alternatives, but the CRUD nature and sibling set make the intended use obvious.

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