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

With no annotations provided, the description carries the full burden of behavioral disclosure. It successfully describes key behaviors: automatic erasure of corresponding Flash blocks before flashing, support for specific file formats, and the address parameter behavior with .hex files. It doesn't mention error handling, completion signals, or performance characteristics, but provides substantial operational context.

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 efficiently structured with a clear purpose statement, supported formats, key behavioral detail (automatic erasure), and parameter explanations. Every sentence adds value, and the information is front-loaded with the most important details first. No wasted words or redundancy.

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?

Given that this is a potentially destructive operation (flashing firmware) with no annotations and an output schema exists, the description provides good coverage. It explains the core operation, file formats, automatic erasure behavior, and parameter semantics. The main gap is lack of explicit warning about the destructive nature, though the 'automatic erasure' mention implies data loss.

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?

With 0% schema description coverage, the description must compensate, which it does effectively. It explains both parameters: file_path as the absolute path to the firmware file, and address as the starting address for flashing with special handling for .hex files. The description adds meaningful context about format-specific behavior that the schema alone wouldn't provide.

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 specific action ('燒錄韌體檔案' - flash firmware file) and target resource ('目標晶片的 Flash 記憶體' - target chip's Flash memory). It distinguishes itself from siblings like jlink_erase_chip (which only erases) and jlink_memory_write (which writes raw data rather than firmware files).

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?

The description provides clear context about when to use this tool - for flashing firmware files in specific formats (.hex, .bin, .srec) to Flash memory. It mentions that .hex files typically ignore the address parameter, which helps guide usage. However, it doesn't explicitly state when NOT to use it or name specific alternatives among the siblings.

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