unpin_all_forum_topic_messages

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

The annotations already convey that this is a state-changing (readOnlyHint=false), idempotent, and non-destructive operation. The description adds no further behavioral context, such as irreversibility, permissions, or side effects, and essentially restates the tool name.

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, direct sentence with no wasted words. It is front-loaded and concise, earning a top score for brevity even though it lacks depth.

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?

The description fails to distinguish a regular forum topic from the general forum topic, which is a critical distinction given the sibling tool. It also does not mention return values or any other relevant context, leaving the description incomplete for a tool that could be easily confused with its sibling.

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 100%, with both parameters (chat_id, message_thread_id) clearly described in the schema. The description does not add additional parameter semantics, but the schema is sufficient, warranting the baseline score.

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 identifies the action (unpin) and target (all messages in a forum topic), which is sufficient for basic understanding. However, it does not explicitly distinguish this from the sibling unpin_all_general_forum_topic_messages, although the schema's message_thread_id and the tool name imply specificity.

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?

No guidance is provided on when to use this tool versus alternatives such as unpin_all_general_forum_topic_messages or unpin_chat_message. The description simply states what it does without any contextual selection criteria.

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