forward_media_to_saved

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

With no annotations, the description must disclose behavior. It states forwarding to saved messages, but does not mention permissions, rate limits, or whether only media messages are supported (despite the tool name including 'media'). The output schema exists but is not referenced.

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 concise sentence that immediately conveys the tool's purpose. No unnecessary words or structure issues.

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?

Despite the tool being simple, the description lacks details on parameter meanings, error conditions, and behavioral nuances. The output schema exists but is not explained. This leaves significant ambiguity for an agent.

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 0%, and the description provides no explanation of the 'chat' or 'message_ids' parameters. An agent cannot infer that 'chat' refers to the source chat or what message_id values are valid. This is a critical gap.

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 tool forwards messages to 'Saved Messages', which is a specific and distinct action. The verb 'forward' and resource 'to Saved Messages' are precise, and it differentiates from sibling tools like 'forward_messages' (which forwards to other chats).

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 usage for saving messages for later use, but does not explicitly state when to use this tool versus alternatives (e.g., 'forward_messages' for other recipients). It lacks explicit guidance on context or exclusions.

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