Publish GIF Thread

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

Annotations provide limited behavioral context (no readOnly or destructive hints). The description adds the two-step publishing flow and return of Media ID, but does not cover authentication requirements, rate limits, or side effects beyond what is implied.

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, with a clear two-line intro followed by an Args section and return statement. No superfluous information; every sentence adds value.

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 tool with 6 parameters and no output schema, the description adequately explains the process and expected result. It does not cover error cases or rate limits, but the essential workflow is clear.

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 lists all parameters with clear summaries, echoing the schema descriptions but adding context like the two-step flow and return value. With 83% schema coverage, the description adds useful structure without significant duplication.

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 it publishes a GIF post to Threads using a GIPHY URL, and mentions a two-step flow. This distinguishes it from sibling tools like threads_publish_image or threads_publish_video, which handle other media types.

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 implicitly guides when to use this tool by specifying it is for GIF posts via GIPHY. However, it lacks explicit guidance on when not to use or alternatives, leaving the agent to infer from context.

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