Post attachment admin

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

Annotations already declare this is a non-read-only, non-destructive, open-world operation. The description adds the useful behavioral detail that this is the admin path, but it does not explain overwrite behavior, auth requirements, upload constraints, or expected effects beyond what annotations already imply.

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 front-loaded phrase with no wasted words. However, it is so terse that it omits nearly all operational context, even though conciseness itself is good.

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?

This is a mutating upload endpoint with four undocumented parameters and no output schema, so the description should carry more weight. It does not explain the required cipher_id, payload structure, admin authentication, or how it differs from the many sibling attachment upload operations.

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?

The schema has four parameters with 0% description coverage, and the description does not mention any of them, including the required cipher_id or the form, params, and json_body fields. For a four-parameter upload tool, this leaves parameter usage entirely undocumented.

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 verb (Upload) and resource (attachment), plus the admin-path variant. It is clearer than a tautology, but it does not distinguish this operation from sibling attachment upload tools such as post_attachment or post_attachment_v2 beyond the word 'admin'.

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?

There is no guidance on when to use this admin attachment upload versus non-admin, v2, share, or data variants. It also does not mention prerequisites such as administrator authentication or the expected use case.

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