set_comment_thread_status

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

No annotations are provided, so the description must disclose behavioral traits on its own. It clearly indicates this is a state-changing operation by using 'set', but it does not mention any side effects, permissions required, reversibility, or what happens if the thread is already in the target status. While the operation is straightforward, the description lacks depth on consequences, which is important for a mutation tool without annotation support.

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 composed of three concise sentences. The first sentence states the core purpose, the second explains when to use each status, and the third provides a pointer to find the required ID. Every sentence has a purpose, and the structure is front-loaded with the most critical information. There is no redundancy 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 setter with no output schema, the description covers the purpose, the usage context, and how to find a required parameter. It does not describe return values or error behavior, but for this type of operation, that is often obvious (success/failure). Given the low complexity and complete parameter documentation, the description is sufficiently complete, though it could mention idempotency or permission requirements.

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 input schema already documents all three parameters with 100% coverage, so the baseline is 3. The description adds value by explaining the semantics of 'status': it clarifies that 'resolved' is used when feedback is fully addressed and 'open' for reopening, which goes beyond the enum definition. It also contextualizes how commentThreadId relates to other tools. However, it does not add information about fileId, which the schema already covers, so the added value is moderate.

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: 'Set the workflow status of one comment thread to resolved or open.' It specifies the resource (comment thread), the verb (set), and the two allowed states. It also explains when to use each state, distinguishing it from siblings like get_comment_thread or list_comment_threads which read or list, while this one mutates.

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 explicitly says when to resolve ('once its feedback has been fully addressed') and when to reopen ('if more work turns out to be needed'). It also recommends using list_comment_threads or get_comment_thread to find the commentThreadId, which is practical guidance. However, it does not explicitly mention when not to use this tool or what to do if the thread is already in the desired state, which is a minor gap.

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