mal_bulk_update_anime

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

With no annotations provided, the description carries the full burden. It only mentions the transformation and the dry_run parameter. It fails to disclose important behavioral traits such as authentication requirements, whether the operation is reversible, rate limits, or error handling.

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, front-loaded sentence that communicates the core purpose with no redundant words. It is efficient and to the point.

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 bulk operation with 4 parameters and no output schema, the description is too brief. It omits critical context such as return format, behavior when limit is reached, atomicity, and error scenarios. The example is helpful but insufficient.

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 the schema already documents all parameters. The description adds a usage example but does not clarify the implicit selection logic (e.g., that it updates all anime matching from_status). Baseline 3 is appropriate as the description provides marginal added value.

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 explicitly states the tool performs bulk anime status updates, with a concrete example ('changing watching→dropped/on_hold'). It is clearly distinguished from siblings like mal_update_anime (single update) and mal_bulk_delete_anime.

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 provides a clear context for use (bulk status changes) and includes a practical example. However, it does not explicitly state when not to use this tool or mention alternatives (e.g., mal_update_anime for single entries).

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