initialize_season

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

It discloses that selection is automatic, persistent, and returns choices without guessing. However, it does not mention potential side effects like overwriting context, required configuration, or failure modes. With no annotations, this is a moderate disclosure.

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 in the main paragraph plus a behavioral note, efficiently front-loaded with the core purpose. No redundant information.

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?

The tool has an output schema but no annotations. The description covers the main behavior but leaves parameter semantics and edge cases (e.g., season validation, include_players effect) unaddressed. Overall adequate but not thorough.

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?

None of the three parameters (season, league_id, include_players) are described in the tool description beyond an indirect reference to league_id for re-calling. Schema coverage is 0%, so the description fails to compensate for missing parameter meaning.

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 states a specific verb 'Discover' with a clear resource ('configured Sleeper user's league, roster, and draft') and scope ('for a season'). It differentiates from sibling tools like get_season_context by emphasizing initialization and persistence of context.

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 explains automatic selection behavior and instructs the agent to call again with league_id when multiple leagues exist. However, it does not explicitly mention alternative tools or when to use them.

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