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

Annotations already declare destructiveHint=true, non-idempotent, and closed-world, so the safety bar is partly met. The description usefully adds that execution needs an exact expected_host, explicit write switches, dependency acknowledgment, and a request_id for de-duplication, but the four allow_* / acknowledged_vm_ids safety gates are never explained, leaving real destructive-side behavior opaque.

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 description is a single dense, front-loaded block that leads with the managed resource and operations before moving to prerequisites and execution requirements. It wastes no sentences, though the compressed phrasing borders on cryptic in places.

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 described, and annotations cover the destructive profile. But for a 9-parameter destructive mutation tool with zero schema documentation, the description omits the meaning of most safety switches and the accepted action values' semantics, leaving the agent under-equipped to call it safely.

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% across 9 parameters, so the description carries the full burden. It only illuminates expected_host, request_id, and the presence of 'write switches' and 'dependency confirmation'; dry_run, arguments, and the four impact-permission flags are left entirely unmapped, so an agent cannot know what allow_disruption or allow_protected_impact actually gate.

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 concrete resource ('time 管理') and enumerates the two operations it exposes (configuration_update, clock_update), so an agent can tell this is host time/NTP configuration rather than the sibling service_manage or host_manage tools. It stops short of explicitly contrasting itself with those neighbors, which keeps it from a 5.

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 gives real workflow guidance: consult resource_schema/get first, rely on the default preview, and only then execute with expected_host, write switches, and dependency confirmation. However, it never states when NOT to use the tool or how it differs from siblings that also mutate host settings, so usage is only partially specified.

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