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

With no annotations, the description carries the full burden. It conveys the semantic nature of the data (read-only ledger of replication/refutation counts via 读取), but says nothing about return format, ordering, or whether the ledger can be empty. Adequate but with clear gaps.

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 tightly-scoped sentences: the data source first, then the use case. Front-loaded and free of filler, though the second sentence slightly restates the first's implication.

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 zero-param read tool with no output schema, the description usefully explains what is returned conceptually (per-proposition counts of replication vs. refutation), which compensates for the absent output schema. Formatting and edge cases remain unstated.

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?

The tool takes zero parameters, so per the rubric the baseline is 4. There is nothing for the description to clarify beyond that.

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 (读取独立复核台账) plus the content it exposes (each proposition's independent replication/refutation counts). It is clearly distinct from every sibling tool, none of which touch replications, though it never names a contrast 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?

The 用途 (purpose) clause gives clear when-to-use context: gauge how much external verification the site's conclusions actually have. It supplies no exclusions or named alternatives, but no sibling overlaps, so the guidance is adequate.

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