get_league_transactions

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

No annotations are provided, so the description carries the full behavioral burden. It discloses that transactions are grouped by processing rounds, that higher rounds are more recent, and describes return contents including enriched player data from cache. However, it doesn't state whether this is a read-only operation (implied by 'Get'), or any rate limits or auth requirements. For a read operation this is moderately transparent but incomplete.

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 includes a structured Args and Returns section, which is helpful, but the Returns section is verbose with bullet points listing every field, some of which is redundant given the output schema exists. The initial sentence is front-loaded. Overall it's more verbose than necessary for a single-parameter tool with an 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?

Given the output schema exists, the description needn't detail return values, yet it does provide useful context about enriched player data and FAAB bids. For a read-only tool with one parameter and no annotations, the description covers the parameter well and gives some behavioral context. However, it lacks guidance on tool selection among siblings and doesn't clarify the integer/string discrepancy, leaving minor gaps.

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%, so the description must compensate. It explains that 'round' is the transaction round/week number, defaults to 1, can be an integer or string (though schema says integer only – slight inconsistency), must be positive, and that higher rounds represent more recent transactions. This adds significant meaning beyond the bare schema, but the string/integer flexibility contradicts the schema and the week/round dual meaning is ambiguous.

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 specific verb+resource: 'Get waiver wire and trade transactions for the Token Bowl league.' This is clear. However, it doesn't distinguish itself from the sibling get_recent_transactions or get_waiver_wire_players, leaving ambiguity about when to choose this tool over those.

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 explicit guidance on when to use this tool versus alternatives like get_recent_transactions or get_waiver_wire_players. The round parameter is explained but not the context for choosing this tool. Usage is only implied from the purpose.

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