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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description still adds value by disclosing what the payload contains — variable date, venue, purse/roster rules, FAQs and currency-rate blocks delivered as labelled text and lists — so the agent knows output is loosely structured, not tabular.

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?

Two sentences, no filler, with the sequencing constraint placed first and the return shape second. Every clause carries information an agent would otherwise have to infer.

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 an output schema and read-only annotations present, the description need not restate returns or safety, and it still characterizes the content. Minor gap: it doesn't note that both parameters are optional and default to ipl/2026, meaning a parameterless call succeeds — but the schema documents that.

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 both parameters (year, tournament) already document accepted values and default behavior, so the schema does the heavy lifting. The description only implies that a tournament/year pair is required input without adding syntax or constraint detail beyond the schema. Baseline 3 applies.

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?

States a specific verb and resource: read that edition's Auction Guide for a tournament/year. It explicitly frames itself as the follow-on to cricbuzz_auction_seasons, so the agent can distinguish it from the season-listing and auction_live/results siblings without opening schemas.

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?

"Use this after choosing tournament and year from cricbuzz_auction_seasons" gives a clear prerequisite and ordering that points at the correct upstream tool. It does not name any when-not conditions or other alternatives (e.g. auction_live, auction_results), so routing guidance is one-directional rather than complete.

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