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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety and network scope are covered. The description adds the upstream dependency on cricbuzz_matches and the breadth of returned sections, but nothing about partial availability for abandoned/no-result matches, live vs completed behavior, or rate limits — relevant for a live-cricket source.

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 with no filler, and the payload inventory is front-loaded ahead of the parameter instruction. Every clause carries selection or invocation value.

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 one required parameter at full schema coverage, an output schema, and read-only annotations, the description covers what an agent needs to select and call it. The only gap is behavior for non-completed or rain-affected matches, which the agent cannot infer.

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 the single MatchURL property already documents itself as 'Canonical Cricbuzz live-cricket-scores URL returned by /cricbuzz/matches'. The description restates the same provenance constraint rather than adding syntax, validation, or fallback guidance, so the 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 ('Returns') and resource (a match's scorecard), then enumerates the payload contents — innings, batter and bowler lines, totals, extras, powerplays, wickets, partnerships, toss, result. That enumeration lets an agent distinguish it from cricbuzz_match_graphs or cricbuzz_match_overs without opening the schema, though no sibling is explicitly named.

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?

The second sentence gives a concrete prerequisite: pass the canonical match_url returned by cricbuzz_matches, which routes the agent through the correct discovery tool first. It does not state when to prefer cricbuzz_match_facts or cricbuzz_match_overs instead, so there are no explicit exclusions.

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