write_file

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

Annotations already show this is a mutation (readOnlyHint=false) and not idempotent. The description adds useful context about bounded writes and sound-file support, but it does not explain overwrite behavior, failure conditions, or whether content requires special encoding.

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 a single compact sentence with the action front-loaded and no filler words. It is appropriately concise, though it sacrifices detail for brevity.

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 write operation with three parameters and no output schema, this description is too thin. It omits parameter semantics, overwrite behavior, file-size bounds, and encoding expectations, so an agent would likely need to guess or rely on external knowledge to call this tool correctly.

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?

Schema description coverage is 0%, so the description must compensate, but it only says 'data or sound files' without connecting this to the name, content, or overwrite parameters. The schema provides bare titles and a default, so an agent still lacks crucial parameter meaning such as how content should be formatted or what name represents.

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 ('Write') and resource ('bounded data or sound files to NXT user flash'), clearly distinguishing this from siblings like read_file, delete_file, and list_files. The 'bounded' qualifier adds useful specificity about file size constraints.

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 implies when to use the tool: when a file needs to be created or persisted on NXT user flash. However, it provides no explicit when-not-to-use guidance and does not name alternatives, leaving usage decisions mostly to inference.

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