update_firmware

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

The description explicitly states that the tool 'simulates' a firmware update, which is a critical behavioral trait not captured by the input schema. This goes beyond the schema and compensates for the lack of annotations, though it does not detail permissions or side effects.

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 concise with a one-sentence purpose and a clear list of parameter descriptions. No redundant information, though the German language might be slightly verbose.

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?

The description covers the purpose and parameter meanings, but lacks information about the return value, success/failure behavior, and does not mention idempotency or side effects. Given no output schema, this gap reduces completeness.

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?

Despite 0% schema description coverage, the description provides meaningful German explanations for each parameter, including examples for new_version and notes. This adds significant value over the schema's bare titles and types.

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 clearly states the tool 'simulates a firmware update for an IoT device', providing a specific verb (simulates) and resource (firmware update). This distinguishes it from siblings like send_command or get_device_status, which serve different purposes.

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 explicit guidance is given on when to use this tool versus alternatives like send_command or device_analytics. The description implies it is for simulation, but it does not state that it should be used for testing or non-production environments.

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