anime_airing_schedule

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

With no annotations, the description carries the full burden. It states the tool returns upcoming broadcasts, is paginated, and credential-free, but lacks details on rate limits, data freshness, error handling, or what happens when no upcoming episodes exist.

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 sentences, front-loads the core purpose, and includes only essential information without redundancy. Every sentence adds value.

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?

Given no output schema, the description lists the return fields and mentions pagination and ordering. It also identifies the data source (AniList). However, it does not specify the format of time fields (e.g., UTC offset) or countdown units, leaving minor gaps.

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 coverage is 100%, so the description does not need to add more, but it does not provide additional context beyond what the schema already offers (page defaults, per_page max). The description's mention of pagination and ordering is tool-level, not parameter-level.

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 identifies the tool as providing an upcoming anime airing schedule with specific return fields (episode number, air time, countdown, normalized title) and ordering (soonest first). It distinguishes itself from sibling anime tools like anime_search or anime_rankings by focusing on the schedule aspect.

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 mentions it is credential-free, implying easy access, but does not provide explicit guidance on when to use this tool versus alternatives like anime_search for finding specific anime or anime_rankings for popularity. There is no mention of when not to use it.

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