Ignore a pending Threads reply

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

Annotations already disclose that this is a non-read-only, open-world, destructive operation. The description adds valuable outcome context: the reply 'stays unpublished', implying it is not deleted but simply left unapproved. It does not discuss reversibility or permissions, but with annotations carrying the safety profile this is a strong addition.

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?

Two short sentences, front-loaded with the core action and outcome, followed by the platform constraint and alternative. Every sentence earns its place with no waste.

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?

Given the presence of an output schema, full parameter documentation, and annotations, the description covers the essential behavioral scope and alternative well. It could optionally clarify the relationship to other comment-state tools, but nothing an agent needs to call it correctly is missing.

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 100% and both parameters (user, commentId) are fully documented there, including the source of commentId. The description adds no additional parameter meaning beyond what the schema already provides, so the baseline of 3 is appropriate.

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 names a specific verb and resource (ignore a reply waiting for approval) and scopes it precisely to Threads posts. It also explicitly distinguishes the tool from the sibling approve_comment, so an agent can identify its function without opening the schema.

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 clearly states the platform constraint ('Threads only') and points to the alternative tool ('to publish it use approve_comment'). It does not explicitly exclude other comment-management siblings like hold_comment or delete_comment, but the primary usage decision is well covered.

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