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

The annotations already declare the tool is read-only and open-world, so the bar is lowered. The description adds real context: results are paged one row-set at a time, and page numbering is one-based. It does not mention rate limits or whether unpaged results are capped, which keeps it from 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?

Three tightly packed sentences, front-loaded with the operation and scope before the dependency and formatting notes. Minor redundancy with schema-documented facts (comma-separated values, one-based paging) means a sentence isn't fully value-adding, so it's not a clean 5.

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 and all ten parameters are documented, so the description needn't explain returns or field meanings. It provides the prerequisite-tool chain and paging semantics that make the call correct. Pagination limits and iteration-until-exhausted guidance are absent, but the definition is broadly complete for a filtered list endpoint.

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%, including enumerated current values for each filter, so the schema already carries the parameter semantics. The description repeats some of it (comma-separated country_ids/statuses, one-based page) but adds little new syntax or edge-case meaning. 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 opens with a specific verb and resource: 'Fetches one page of completed-auction player rows', and quickly clarifies the scope (per-page, with Country/Status/Team/Role/Cap/Sort controls). An agent can tell this apart from cricbuzz_auction_seasons and cricbuzz_auction_options, which are explicitly named as prerequisite lookups. It is not a tautology of the name.

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?

Explicitly names the required workflow: derive tournament/year/currency from cricbuzz_auction_seasons, and pull filter/sort values from cricbuzz_auction_options. That's strong when-to-use guidance. It does not, however, state any exclusion or alternative tool for other needs (e.g., if you just want the seasons list), so it stops short of a 5.

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