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

Annotations already declare readOnly, idempotent, non-destructive, and openWorld, so the safety profile is fully covered elsewhere. The description adds what kind of state is surfaced (steps, pending questions, versions), which is genuinely useful context, but says nothing about ordering, pagination, or credential requirements.

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?

A single front-loaded sentence with the verb first and no filler. It is brief, though it is brief partly because important parameter and usage details were omitted rather than compressed.

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, so return values need not be explained, and annotations cover behavior. Still, for a two-required-parameter call with zero schema descriptions, the definition leaves the agent without guidance on the credential or the service_id pattern, and offers no routing versus sibling read tools.

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 0% for both required parameters (service_id, credential), yet the description does not compensate at all — no mention of the LX-… identifier format or what the credential represents. This is the biggest gap for an agent trying to construct a valid call.

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 (读取/read) and enumerates the concrete resources returned: persisted steps, pending questions, and delivered versions. It is reasonably distinguishable from get_run_result and get_service_overview, though it never names those siblings to sharpen the boundary.

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?

There is no indication of when to choose this over get_run_result, get_service_overview, or get_task_materials, all of which sit adjacent in the sibling list. Usage is only implied by the noun list, with no conditions or exclusions stated.

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