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

With no annotations provided, the description carries the full behavioral burden and does well: it discloses that the figure is displayed verbatim as '未核实' (unverified), that entries are deduped by QY, that the count never enters ranking/tier fields, that content is visible only to the claimed account, and that unclaimed submissions are rejected. Return format is the main omission.

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?

The text is front-loaded, but the entire content is stated twice (English, then repeated in Chinese), which is pure duplication and doubles the length with no added information. Each sentence also packs multiple constraints into dense run-ons, hurting scanability.

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?

For a mutation-style tool with four parameters, no annotations, and no output schema, the description covers the essential behavior: eligibility, rejection behavior, display wording, dedup rules, and ranking exclusion. It is nearly complete, missing only what the response looks like.

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%, so the schema already documents all four parameters including the claimed-id requirement and the internal qy_token note. The description adds no parameter-level formatting or constraint beyond what is in the schema, so the baseline of 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?

The opening clause 'Operator self-report on YOUR OWN claimed MCP listing' gives a specific actor, verb, and resource, and it is distinguishable from siblings like qy_mcp_check and qy_claim. The remainder of the description is a dense block of constraints rather than further purpose definition, but the core action is clear.

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 precondition: only the claimed QY may report, and unclaimed requests are rejected with an explicit reason. However it never names an alternative tool or explains when an agent should choose this over a sibling such as qy_mcp_check, so guidance is implied rather than explicit.

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