firmware_upload

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

No annotations are provided, so the description carries the full burden. It discloses the core side effect (uploading to an FTP server), but does not mention overwrite behavior, required server configuration, authentication, or any other potentially destructive or side-effectful details. For a write operation this is a notable gap.

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 compact and well-structured: a one-sentence summary followed by a clean Args list. Every line earns its place, and the most important information is front-loaded.

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 output schema exists, so return-value details are not required. The description covers all parameters and the upload action, but for a mutation tool with no annotations it still lacks preconditions, side-effect details, and higher-level context about the release config flow. It is adequate for basic invocation but not fully complete.

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's Args block adds meaningful semantics to all four parameters: firmware_path is the .bin file path, board_id is an optional board identifier with release config, remote_filename is the optional FTP filename, and config_path is an optional custom release config. This goes well beyond the bare schema titles, though a bit more detail on how board_id and config_path affect the upload would strengthen it.

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 states a specific action and resource: 'Upload a firmware binary (.bin) to the configured FTP server.' This clearly distinguishes it from siblings like serial_write, ssh_exec, or firmware_build, though it does not explicitly name those alternatives.

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 gives no guidance on when to use this tool versus firmware_build, firmware_release, or other transfer tools. The intended use is implied by the verb 'Upload,' but no context, prerequisites, or exclusions are provided.

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