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 does disclose the return payload, which is valuable given there is no output schema, but it says nothing about failure behavior for an out-of-range season, whether results are cached, or the effect of includeEpisodes=false on the described output.

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?

A single sentence that front-loads the action and resource, then lists the returned fields in order. Nothing is redundant and nothing is padded.

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?

With no output schema and only a 2-parameter object, the description supplies the return shape an agent needs (episode count, air dates, episode list), which is the main contextual requirement. It leaves the includeEpisodes toggle and invalid-season handling unexplained, but overall it is adequate for a tool of this complexity.

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 50%: 'season' is described as 'Season number.' but includeEpisodes has no description at all. The description's mention of 'the episode list' hints at what includeEpisodes controls, yet it never connects the two or explains that setting it false suppresses that list, so it only partially compensates for the gap.

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?

States a specific verb and resource ('Return one season of Family Guy') and even enumerates the payload (episode count, start/end dates, episode list). The singular 'one season' implicitly separates it from get_episode and search_episodes, but no sibling is named explicitly, so it stops short of a 5.

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?

There is no explicit when-to-use, when-not-to-use, or alternative routing guidance. Usage is only implied: the 'one season' framing makes the lookup-vs-search boundary inferable, but an agent gets no statement like 'use search_episodes if you don't know the season number.'

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