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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered. The description adds useful shape information (month grouping, category buckets) but says nothing about result volume or pagination for what it calls the 'full' directory, which matters for a large open-world listing.

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 compact sentences with the resource and scope front-loaded before the filtering note. No filler, though the lowercase parameter names add ambiguity rather than 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?

An output schema exists, so return-value documentation is unnecessary, and the purpose is clear. However, the schema marks all three parameters as required while describing them as optional with defaults, and the description does not reconcile that or explain the size/pagination of a 'full' directory.

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 schema alone documents all three parameters, and the description only restates two of them. Worse, it refers to them as 'q' and 'live_stream' while the schema keys are 'Query' and 'LiveStream', inviting a wrong key, and it never mentions the Category filter that defines the grouping axis.

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 ('Returns the full current and future Cricbuzz series directory'), plus scope details (grouped by month, four categories) that let an agent picture the payload. The 'current and future' qualifier implicitly distinguishes it from cricbuzz_archives, 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?

'Use q or live_stream to narrow the discovered directory' hints at filtering but is really parameter advice, not when-to-use guidance. There is no statement about when to prefer this over cricbuzz_archives, cricbuzz_schedule, or cricinfo_series, and no exclusions or prerequisites.

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