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

readOnlyHint=true already tells the agent this is a safe read, so the description is not obligated to restate safety. It adds the useful scope note that the response combines a version and a local firmware file status, but discloses nothing about staleness, caching, or whether the local file status can be empty/missing.

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 short clause with the content scope front-loaded in the parenthetical; nothing is padded. It is arguably too terse to carry usage routing, but as a sentence it earns its place.

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 with zero parameters and a readOnly annotation the description only needs to state purpose and scope. That is largely covered, with sibling disambiguation the one notable omission.

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?

Zero parameters, so the schema imposes no semantic burden and the baseline is 4. The description correctly adds no parameter discussion where none is needed.

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+resource ('获取完整 OTA 信息') and clarifies the returned content scope ('版本 + 本地固件文件状态'), so the agent knows what comes back. However, it does not distinguish itself from close firmware siblings such as get_firmware_version, check_firmware_update, or get_auto_upgrade_status.

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?

No indication of when to call this versus get_firmware_version, check_firmware_update, or get_auto_upgrade_status, all of which sit adjacent in the sibling list. The agent is left to infer the selection criteria entirely.

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