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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions that content must be base64-encoded, which is a useful constraint, but fails to disclose critical traits such as whether the tool overwrites existing files, creates new ones, requires specific permissions, handles errors, or has rate limits. For a write operation with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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, efficient sentence that directly states the tool's purpose and key constraint. It is front-loaded with the main action and avoids unnecessary details, making it easy to parse quickly without any wasted words.

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 the complexity of a file write operation, lack of annotations, and no output schema, the description is insufficient. It doesn't cover behavioral aspects like file overwriting, error handling, or security implications, and it omits details about return values or side effects. For a tool that modifies the filesystem, more context is needed to ensure safe and correct usage.

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 100%, with both parameters (path and content) well-documented in the input schema. The description adds minimal value beyond the schema by reiterating that content must be base64-encoded, which is already implied in the schema's description. It doesn't provide additional context like path validation rules or content size limits, so it meets the baseline for high schema coverage.

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 verb 'write' and the resource 'file on the filesystem', specifying the action and target. It distinguishes from sibling tools like bytebot_read_file by indicating a write operation rather than read. However, it doesn't explicitly differentiate from other file-related operations that might exist in the broader context beyond the listed siblings.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites like file permissions, when not to use it (e.g., for large files or sensitive paths), or compare it to siblings like bytebot_read_file or bytebot_create_task. Usage is implied only by the tool name and description, with no explicit context.

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