identify_cards_from_images

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

No annotations are provided, so the description carries the full burden. It mentions operational traits (bounded concurrency, independent statuses, up to 10 images) which is helpful, but does not disclose what happens on failure, whether partial results are returned, response format, or any rate-limiting specifics. For a tool with zero annotation coverage, this disclosure is insufficient.

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 extremely short (one sentence), which is concise, but it front-loads operational constraints at the expense of substantive purpose and parameter guidance. The sentence has zero waste but is under-specified - it's brevity rather than effective structure.

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?

Despite having an output schema and a nested-object ImageInput, the tool has 3 undocumented parameters at 0% schema coverage. A batch image-identification tool with multiple parameters (top_k, visual_verify), a nested image input structure, and a substantial sibling list needs far more description to be usable. The 'up to 10' limit and concurrency note are good but insufficient given no annotation support.

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 0%, so the description must compensate, but it explains none of the three parameters (top_k, images, visual_verify). The nested ImageInput schema has fields (image_path, image_base64, language_hint) with defaults and no descriptions. The description adds zero value regarding how to supply images or what top_k/visual_verify control.

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 'Identify up to 10 images with bounded concurrency and independent statuses.' states the tool identifies images, but 'cards' is only in the name. The scope (up to 10 images, bounded concurrency, independent statuses) adds operational detail but does not explain what 'identify' means in this context (presumably identifying Pokémon cards from images). It partially distinguishes from sibling 'identify_card_from_image' (which is singular) but doesn't clarify whether this is a batch variant or different behavior.

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 on when to use this vs alternatives. There's a sibling 'identify_card_from_image' (singular) that overlaps with this tool, but the description never explains when to choose batch over single. No context about prerequisites, error handling, or limits beyond the 'up to 10' mention. No exclusions or alternative recommendations.

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