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

Annotations already declare readOnlyHint=false, idempotentHint=false and destructiveHint=true, so the mutation profile is partially known. The description adds genuine behavioral context beyond that: it requires login and authorization, and it preserves the record across that boundary so the user need not re-answer. It does not, however, explain the destructive/overwrite semantics or the expectedRevision conflict behavior, leaving a meaningful gap for a destructive write.

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?

It is short overall, but the second sentence ('保留刚才的record，登录后继续保存，无需重新答题') largely restates the first in narrative form rather than front-loading the essential scope. Some redundancy without loss of clarity.

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 destructive mutation with a nested object parameter, a concurrency token, no output schema and no annotations covering return or failure behavior, the description leaves too much open. It says nothing about revision mismatches, partial/failed saves, or what the save overwrites, which an agent needs before invoking a destructive tool.

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 only 67%: record and testId are documented in the schema but expectedRevision is not. The description mentions retaining the record but adds no syntax, format or meaning for any parameter, and it does not compensate for the undocumented concurrency token (expectedRevision), which is the riskiest argument here.

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 states a verb and resource ('保存' the completed summary/record), so the basic action is identifiable. However, it frames the tool through a user-flow narrative ('登录并授权后') rather than crisply stating what is persisted, and it never distinguishes itself from the obvious sibling score_assessment, which is only hinted at via '刚才的record'. Purpose is implied rather than precisely scoped.

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 description implies when to call it (after user login and authorization) and notes that the workflow continues without re-answering, which gives usable context. It names no explicit alternative or exclusion, so the agent must infer the ordering relative to score_assessment and assessment_step.

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