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

With no annotations, the description carries the full behavioral burden, and it does disclose one real trait: the caption is plain text (no HTML/markdown formatting). However, it omits file-count limits, ordering behavior, whether sending is destructive/irreversible, and any permission or auth requirements for a mutation-style operation.

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?

A single short sentence with the core action front-loaded and the caption caveat appended in a tightly scoped parenthetical. Nothing is wasted and nothing is buried.

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 send operation with no annotations, no output schema, and an empty parameter schema, the description is too thin. The agent cannot determine where the album is sent (no dialog/chat argument), how the files are passed, or any limits, which is essential for correct invocation.

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 declares zero properties, so per the 0-param baseline this would normally be a 4; but the description explicitly references 'multiple files' and a 'caption', implying inputs that the schema does not define. That mismatch leaves an agent without any documented way to supply the files or destination, reducing the score below baseline.

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 ('Send') and resource ('media album') and distinguishes the operation from the generic 'send'/'upload' siblings by emphasizing multiple files grouped as one album. It stops short of explicitly naming which sibling to prefer for single-file sends.

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 when-to-use guidance: it never says to prefer this over 'send' for single files or over 'upload', nor does it state prerequisites such as a target dialog/chat or an active session. The agent must infer the routing decision entirely.

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