download_task_images

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

With no annotations, the description carries the full burden. It discloses the main behavior (downloads images, saves to a local directory, returns mapping) but omits potential side effects such as file overwriting, directory creation, or handling of missing images. It is transparent about the core action but not exhaustive.

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 two concise sentences that state the action and the return value without any filler. Every word contributes meaning, and it is well-structured for quick scanning.

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 3 straightforward parameters and no output schema, the description adequately covers the purpose, input (task description), and return value (mapping). It lacks some edge-case context but is sufficient for basic selection and invocation. The presence of sibling tools suggests more detail on differentiation could enhance completeness, but it is not critical.

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 100%, so each parameter already has a clear description. The tool description adds no additional parameter context beyond restating that images are saved to a local directory, which aligns with output_dir. It does not go beyond the schema.

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 verb ('Download') with a specific resource ('all inline images from a task description') and destination ('to a local directory'). It also distinguishes from sibling tools like 'download_inline_image' (singular) by specifying 'all inline images' and the return mapping.

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 implies the usage context (downloading all inline images from a task description) but does not explicitly mention when to use this tool over alternatives like 'download_inline_image' or 'extract_inline_images'. There is no direct comparison or exclusionary guidance.

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