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

The annotations already establish that this is a read-only, idempotent, non-destructive operation. The description adds useful behavioral context beyond annotations: members-only picks are counted but omitted, the free tier applies, and the license is CC BY 4.0. It does not cover freshness, pagination, or rate limits, but it adds meaningful return-shape and access-tier context.

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 definition is compact and front-loaded: it names the resource, scope, returned fields, member-pick behavior, and licensing in essentially two dense sentences. The field enumeration earns its place because no output schema is provided.

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, the description does a good job listing returned fields and confidence values, and it explains what is excluded. It is slightly incomplete on freshness, sorting, or whether all current picks for the league are returned, but the core contract is clear.

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 100%, and the single league parameter has a complete enum. The description reinforces the one-league scope but does not add syntax, format, or selection details beyond what the schema already provides, so the baseline of 3 is appropriate.

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 clear resource and scope: free public picks for exactly one league, with the returned fields enumerated. It distinguishes free picks from members-only picks, but it does not explicitly differentiate itself from related siblings such as get_predictions or get_bets_feed.

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?

Usage is implied by 'free public picks' and the note that members-only picks are counted but not shown, which helps an agent understand the free-tier limitation. However, there is no explicit guidance on when to use this tool versus get_predictions, get_bets_feed, or other sibling tools.

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