laliga_subscriptions

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

With no annotations, the description carries full burden. It discloses pagination (20/page) and the return structure. However, it does not state whether the tool is read-only, if authentication is needed, or any rate limits. It provides moderate behavioral 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 description is concise, with a clear one-sentence explanation and a detailed return format. It is front-loaded with the key concept. The return format is somewhat long but necessary given no output schema.

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 list tool with one parameter, the description covers the data model and pagination. However, it lacks context on scope (e.g., all seasons or only current) and how to paginate using offset. Adequate but not complete.

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% and the description does not explain the offset parameter at all. It only mentions pagination without linking to offset usage. The description adds no semantic value over the schema field.

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 clearly explains that the tool returns season instances (subscriptions) for La Liga competitions, with each item's fields listed. It distinguishes from siblings by defining 'subscription' as a competition's season, but doesn't explicitly state the verb (e.g., list) and could contrast with laliga_subscription (singular).

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?

No guidance on when to use this tool versus other La Liga tools like laliga_competitions or laliga_subscription. No mention of prerequisites, alternatives, or context for using offset for pagination.

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