b24_disk_file_content

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

There are no annotations, so the description itself must carry the behavioral burden. It discloses the main behavior (base64 vs save_to, WAF-403 fallback, large-file guidance), but it does not mention authentication/read-only implications, error handling, or side effects of writing to a server path.

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?

Two short sentences front-load the core purpose and then add the key conditions. Every phrase contributes, with no filler or repetition of schema details.

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 download tool with no output schema and no annotations, the description gives the essential mode selection but omits response shape, error behavior, and how to choose between this and b24_disk_file_get. It is adequate for a simple 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?

Schema coverage is high (80%), so the schema already documents most parameters. The description reinforces the save_to-vs-base64 choice for large files and the WAF-403 trigger, but adds little beyond what the parameter descriptions already state.

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 operation ('Скачивает файл с MCP-сервера') and the two output modes (base64 or save_to), so an agent can tell it downloads file content rather than listing or uploading. It does not explicitly distinguish it from sibling b24_disk_file_get, but the core purpose is clear.

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?

It gives concrete conditions: use this when DOWNLOAD_URL is inaccessible externally (WAF 403) and use save_to for large files. It does not name alternative tools or state explicit when-not cases, so it stops short of full routing guidance.

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