get_thread_metadata

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

No annotations are provided, so the description carries full burden for behavioral disclosure. The verb 'Get' implies read-only, but the description does not explicitly state that the operation is safe, idempotent, or requires any specific permissions. It lacks details on what happens if the thread_id is invalid or if the user lacks access.

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 concise and front-loaded with the core purpose. The Args section is slightly redundant but not overly verbose. Every sentence is brief, though the Args block could be omitted since the schema already defines the parameter.

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 simple getter with one parameter and an output schema, the description covers the basic purpose and parameter. It does not mention error handling or edge cases, but given the tool's simplicity and the presence of an output schema, it is reasonably complete. Slightly more context (e.g., 'Returns metadata for an existing thread') would improve clarity.

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 description's 'Args' section restates the parameter name and a generic description ('The thread ID') which adds no value beyond the input schema. With schema description coverage at 0%, the description fails to provide any additional semantic or format constraints (e.g., expected format, length, or example values).

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 action ('Get') and the resource ('triage metadata for a thread') and specifies the components: tags, status, and assignment. It effectively distinguishes from sibling tools like get_thread_messages (which retrieves messages) or tag_thread (which modifies tags).

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 does not provide explicit guidance on when to use this tool versus alternatives like assign_thread or set_thread_status. The name implies a read operation, but no usage context or exclusions are mentioned, leaving the agent to infer from sibling names.

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