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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds genuine behavioral context beyond that: a completed auction may return featured players instead of live bid events, which prevents the agent from misreading an empty live feed as an error. No freshness/live-polling semantics are given, keeping it below a 5.

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, zero waste. The prerequisite is front-loaded and the caveat about completed auctions follows it – a well-ordered, appropriately sized definition.

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?

An output schema exists, so return-value detail is not required, yet the description still explains what kind of content comes back (live bid events vs. featured players). Combined with fully documented parameters and safety annotations, only live-freshness expectations are left unaddressed.

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%, so all three parameters already carry their own valid-value documentation; the baseline of 3 applies. The description reinforces the lineage (values come from cricbuzz_auction_seasons) but adds no format or constraint detail beyond the schema.

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 ('read') and a specific slice of the auction resource: the edition's Live-tab status plus featured/editor-pick players. That scope naturally separates it from cricbuzz_auction_results and cricbuzz_auction_upcoming, but no sibling is named explicitly, so differentiation is inferred from the 'Live-tab' framing rather than stated.

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, year and currency from cricbuzz_auction_seasons' gives a clear prerequisite and sequencing step, which is exactly what an agent needs before calling. It stops short of naming when to prefer a different sibling (e.g., results for a finished auction), leaving that to inference.

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