unlock_thread

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

No annotations are provided. The description states the core behavior (unlock and re-enable comments) but does not disclose whether the operation is idempotent, requires special permissions, or what occurs if the thread is not currently locked. This is minimal yet accurate.

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 very concise and front-loaded with the purpose, followed by a clear Args block. No unnecessary words or fluff.

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 one-parameter mutation, the description covers the action and parameter sourcing. However, with no annotations and no usage alternatives, it leaves gaps around idempotency and permissions. The existence of an output schema means return value details are not required.

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 only defines thread_id as an integer with no description. The description adds meaning by labeling it 'The global thread ID' and directing users to list_threads or search_threads for the value, compensating for the schema's lack of detail.

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 uses the specific verb 'Unlock' and identifies the resource 'thread', with the clarifying effect 'allow new comments again'. This clearly distinguishes it from lock_thread and other thread-related tools.

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 provides no guidance on when to use this tool instead of alternatives like lock_thread or delete_thread. It only explains the action and parameter source, not the conditions or scenarios for invocation.

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