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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds that the response includes the pre-match/metadata layer (toss, officials, squads), but says nothing about auth, rate limits, or behavior for matches where toss hasn't occurred.

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 payload enumeration comes first and the input-sourcing instruction second, so the most decision-relevant information is front-loaded.

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 present and annotations covering safety, the description needs only to frame scope and input provenance, which it does. It stops just short of noting that toss/squad data may be absent before the match starts.

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%, so the parameter is already documented; baseline is 3. The description adds real value by naming the upstream tool that produces the URL, but it spells the parameter 'match_url' while the schema uses 'MatchURL', a minor naming mismatch an agent must reconcile.

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 gives a concrete verb ('Returns') and enumerates the exact payload: officials, venue, guide link, toss, and both teams' Players/Bench/Support Staff groups. That enumeration effectively distinguishes it from cricbuzz_scorecard or cricbuzz_match_overs, though no sibling is named explicitly.

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 states a prerequisite source for the input ('Pass match_url from cricbuzz_matches'), which is genuinely useful routing context. However, there is no statement of when to prefer this over cricbuzz_scorecard or other match-level siblings, and no exclusions or edge cases.

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