Get Firmware Version

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

readOnlyHint=true already declares the safe read profile, so the description need not restate safety. It adds the informational scope (version plus upgrade availability and channel), which is mild context, but says nothing about caching, frequency of refresh, or how the values relate to the upgrade tools. Adequate but not rich beyond the annotation.

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?

Two short, front-loaded sentences with no padding. The return-field list is somewhat redundant given an output schema exists, which is the only minor inefficiency.

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 zero-parameter read tool with annotations and an output schema, the description covers purpose and scope sufficiently; it needn't explain return values since the output schema does. The only real gap is absence of routing guidance against the several firmware/version-related siblings.

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 baseline of 4 applies. The schema is trivially complete and there is nothing the description could add about inputs.

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 verb+resource (get firmware version) and adds the scope of also surfacing available upgrade info. It is clear what the tool does, but it does not differentiate itself from close siblings such as get_version_info, get_ota_info, or check_firmware_update, which an agent must disambiguate among.

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 when-to-use guidance, no exclusions, and no pointer to the sibling that would be chosen instead (e.g. check_firmware_update for triggering a check, start_firmware_upgrade for acting on the result). The agent is left to infer the selection context entirely.

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