Find bye-week conflicts on a roster

get_bye_conflicts
Read-onlyIdempotent

Given a list of players, report which bye weeks two or more of them share. Use this for roster planning and draft questions about stacking byes.

A4.1/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false, covering the safety profile. The description adds that conflicts are reported only when two or more players share a bye week, which is useful but does not disclose additional behavioral details such as output ordering or handling of unmatched players.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences deliver the core behavior and intended use with no filler. The operation is front-loaded and every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool has one well-documented parameter, strong annotations, and an output schema. The description covers what the tool does, how to use it, and when to use it, leaving no meaningful gap for an agent to call it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, with the players parameter already described as 'Player names, two or more.' The description's phrase 'Given a list of players' adds no new semantic detail beyond the schema, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: given a list of players, report shared bye weeks. It clearly distinguishes itself from sibling tools like get_player and compare_players by focusing on bye-week conflict aggregation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description explicitly gives the intended use: roster planning and draft questions about stacking byes. It does not name alternative tools or exclusions, but the use case is clear enough for an agent to select this over siblings.

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