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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful behavioral context about what comes back (five-dimension scoring plus revision suggestions), but says nothing about score scale, depth, or how strict the critique is.

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 definition is two short, front-loaded fragments with no filler, and the user-intent clause precedes the output clause. It loses a point for restating the title (标书评审) at the start and for keyword-style phrasing rather than a complete sentence.

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 single-parameter, read-only tool with no output schema, the definition is close to sufficient, but it leaves the '五维评分' unspecified — the five dimensions are never named, and no indication is given of output shape or length. An agent can invoke it, but cannot predict what it receives.

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?

With one parameter at 100% schema description coverage, the schema already explains that proposal_text is the full body and must meet the platform's ≥100-character minimum. The description adds no format or length guidance beyond that, 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 description names a specific resource (标书/方案正文) and concrete actions (打分、找问题、提修改意见、五维评分), so an agent knows this is a scoring/critique tool rather than a generator. It does not, however, distinguish itself from near-siblings such as act_paper_review, act_pre_review, or act_deep_review, which also review text.

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 trigger is implied clearly: use it when the user pastes proposal/plan body text and wants scoring, problem-finding, or revision advice. There is no explicit when-not guidance and no routing to the review-oriented siblings, so the agent must still infer which review tool applies.

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