get_mural_widget

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

No annotations are present, so the description must carry the transparency burden. 'Get' implies a read-only operation, but the description does not explicitly state side-effect-free behavior or any additional constraints such as permissions or error conditions. It is adequate but minimal.

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 very brief, but it duplicates parameter information already present in the schema with the 'Args:' block. This redundancy is unnecessary, though the text is not bloated.

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 get-by-ID tool with an output schema, the description is sufficient to explain the basic purpose. However, it lacks any mention of how this tool relates to sibling tools or when it should be selected, leaving the agent to infer usage from the name alone.

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?

The schema includes only titles and types for mural_id and widget_id. The description repeats 'The mural ID' and 'The widget ID', which adds no meaning beyond the schema field names. The coverage gap is not compensated.

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 single widget is fetched by its ID. It distinguishes itself from sibling tool get_mural_widgets (which lists widgets) by emphasizing 'single' and 'by its ID'.

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 given on when to use this tool versus alternatives like get_mural_widgets or get_mural. The context is implicit: use when you have a widget ID, but no exclusions or alternate tool references are provided.

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