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

Annotations already declare readOnlyHint=true, and the description adds useful behavioral context: season_id comes from get_series_details and max_episodes caps the result count with a default of 20. The phrase 'all episodes' is slightly at odds with that cap, but the cap is disclosed in the Args section, so this is not a serious gap.

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 English text is front-loaded with purpose and prerequisite, followed by a clean Args block. The Arabic duplicate is redundant for an agent, but the overall structure is scannable and not padded with filler.

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 simple read-only, two-parameter tool with an output schema, the description supplies the purpose, prerequisite call, and parameter semantics needed to invoke it correctly. The only minor gap is not explicitly reconciling 'all episodes' with the default max_episodes cap, though that cap is documented in Args.

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%, but the description fully compensates by explaining both parameters: season_id is the ID obtained from get_series_details, and max_episodes is the maximum number of episodes to return with its default. This adds real meaning beyond the bare integer types in 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 opens with a precise operation: 'Get all episodes in a specific season.' It names the resource (season episodes), the key identifier (season_id), and clearly separates this from series-level tools like get_series_details and get_latest_episodes.

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 explicitly instructs the agent to call get_series_details first to obtain season IDs, giving a clear prerequisite and usage order. It does not list exclusions or alternative tools, so it stops short of a full 5.

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