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

Mentions 'season' filtering but schema has no season parameter, causing inconsistency. Annotations already cover read-only and idempotent behavior; description adds confusion rather than clarity.

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?

Single sentence, 12 words, front-loaded with key action. Compact but could add more clarity without bloat.

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 2-param tool with output schema, description is adequate but the missing season parameter creates a gap. Does not address sibling differentiation or return values beyond schema.

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?

With 0% schema coverage, description adds minimal meaning: 'whitelisted public team profile' provides context but does not explain the league or team parameters. Season reference is unhelpful.

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?

Clear verb 'return' and specific resource 'whitelisted public team profile' with scope 'for the requested season'. Distinguishes from siblings like get_player_profile.

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?

Implies context for team profiles but no explicit when-to-use or when-not-to-use compared to numerous sibling tools. Lacks guidance on alternatives.

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