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

Annotations already declare readOnlyHint and openWorldHint, and the description adds genuinely new behavior: no-NewsArticle editions return not found or an upstream parse error reflecting Cricbuzz's response, and the payload shape includes public NewsArticle body plus dynamic tags. It stops short of describing payload stability or field variance across editions.

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?

Three short sentences, front-loaded with the selection condition followed by the input source and the return/error behavior. Nothing is redundant, though the opening clause defers the actual resource name to the tab label rather than stating the operation directly.

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, full annotations, and 100% parameter documentation, the description covers the remaining gaps: prerequisite source, content returned, and failure modes. Only the absence of guidance on alternatives when the tab doesn't exist keeps it from being complete.

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 coverage is 100% and both parameters enumerate their valid values (ipl/wpl/sa20/hunm/hunw and year lists), so the schema already carries the parameter semantics. The description adds only provenance ('from cricbuzz_auction_seasons'), which is a workflow hint rather than new meaning about the parameters themselves — baseline 3 is appropriate.

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 identifies a specific resource (the Auction Live Blog tab for a tournament edition) and states what the result contains (NewsArticle body plus dynamic series/team/topic tags). It lacks a crisp leading verb like 'fetch/retrieve' and leans on 'Use this for...' phrasing, so an agent infers the purpose rather than reading it stated outright.

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?

It gives an explicit precondition ('an edition that exposes the Auction Live Blog tab') and an explicit data-dependency ('Pass tournament and year from cricbuzz_auction_seasons'), which tells the agent how to obtain valid inputs. It does not name a fallback sibling (e.g. cricbuzz_auction_news or cricbuzz_auction_info) for editions lacking the tab.

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