playoff_bracket

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

No annotations are provided, and the description 'as recorded in the Google Sheet snapshot' only implies a read-only nature. It does not disclose side effects, return format, or any limitations, so the description carries significant burden that is largely unmet.

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 a single concise sentence with no filler. Every word contributes to identifying the resource and source, and it is appropriately short for a tool with no parameters.

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 and no parameter guidance, the description should explain what the bracket contains (e.g., teams, rounds, matchups) or when it is current. It only labels the resource as 'the 2026 playoff bracket', leaving the agent to guess its structure and behavior.

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?

The tool has zero parameters, so there is nothing for the description to add. The baseline of 4 applies because the schema already fully describes the parameter surface area.

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 identifies the resource (the 2026 playoff bracket) and its source (the Google Sheet snapshot), which lets the agent distinguish it from the projection-focused sibling `playoff_projection`. However, it lacks an explicit action verb such as 'get' or 'retrieve', so the purpose is clear but not fully specified.

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?

There is no guidance about when to use this tool versus its siblings like `playoff_projection`, `standings`, or `schedule`. The description does not state contexts, exclusions, or alternatives, leaving the agent to infer when this tool is appropriate.

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