unpin_message

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 disclosing side effects. It only states the operation itself and says nothing about reversibility, permissions, failure conditions, or what happens if the message is not pinned.

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 single sentence is short and front-loaded, which is structurally clean. However, it is under-specified rather than concise, containing no substantive information beyond what the tool name already conveys.

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?

With no annotations and no parameter guidance, this one-line tautology is insufficient for an agent to select and call the tool correctly. The presence of an output schema covers return values but not usage context, behavioral effects, or parameter semantics.

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 0%, and the description mentions neither 'chat' nor 'message_id'. The schema only provides types and required status, so the agent receives no additional semantic or format guidance for either parameter.

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 translates to 'Unpin a message,' which restates the tool name 'unpin_message' almost verbatim. It identifies the verb and resource but adds no detail beyond the name and does not actively differentiate from the sibling tool pin_message.

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 gives no guidance on when to use this tool versus alternatives such as pin_message or other message tools. There is no mention of prerequisites, exclusions, or context in which unpinning is appropriate.

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