Publish Link Thread

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

Annotations are all false, providing no behavioral hints. Description states 'publishes' which indicates creation but lacks details on side effects, idempotency, or error conditions. Minimal beyond schema.

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?

Description is short and front-loaded with purpose. Arg list is clear. Slightly underspecified but earns its place without verbosity.

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?

No discussion of return values, authentication requirements, rate limits, or expected behavior after publishing. Incomplete for a tool that creates content on a social platform.

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?

Description briefly explains 'text' and 'link_attachment' but ignores optional parameters 'reply_control' and 'response_format'. Schema descriptions cover 60% of parameters; description adds marginal value by linking text to URL inclusion.

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?

Description uses specific verb 'publishes' and resource 'thread post with a link attachment,' clearly distinguishing it from sibling tools like threads_publish_text, threads_publish_image, etc.

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 explicit guidance on when to use this tool vs alternatives. Usage is implied (for link posts) but no exclusions or comparisons provided.

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