update_home_section

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

Annotations only provide destructiveHint=false. The description adds a meaningful behavioral detail: the update requires all fields, implying a full replace rather than a merge. However, it does not describe side effects, handling of an unknown ID, or any output behavior; with such sparse annotations, more transparency would be valuable.

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 filler, and the most important constraint ('all fields must be supplied') is front-loaded after the action. 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?

For a simple six-field update, the description plus schema is minimally viable: the ID source is documented in the schema, and field names are fairly self-evident. But there is no output schema, no behavior about validation or errors, and no context on what happens to the existing section beyond overwrite semantics.

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%, with only homepage_entity_id documented in the schema. The description adds no parameter-level meaning beyond restating that all fields must be supplied, which the schema already encodes via required fields. An agent must infer semantics from parameter names alone.

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 a specific verb ('Update') and resource ('home page story section'), and the requirement 'all fields must be supplied' distinguishes this from partial edits. The sibling names add_home_section/remove_home_section/list_home_sections make the intended operation unambiguous.

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 clearly frames this tool as the way to modify an existing home section and signals that a complete field set is required. It does not explicitly name add_home_section for creation or remove_home_section for deletion, but the context is clear enough to route an agent correctly.

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