ig_publish_story

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

Adds one behavioral trait (24-hour expiry) beyond schema, but does not disclose other important behaviors like authorization scope, rate limits, or whether publishing overwrites an existing story. With no annotations, the description carries the burden but remains minimal.

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 with no filler. Front-loaded with the core action and a key behavioral note. 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?

Adequate for a 2-parameter tool with simple inputs, but lacks completeness: no mention of return values, media requirements (e.g., aspect ratio), or error conditions. Could better support agent decision-making.

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?

Input schema covers both parameters (media_type, media_url) with descriptions. The tool description adds no extra parameter information, so baseline 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?

Description clearly states it publishes a Story (image or video) and notes that stories disappear after 24 hours. This differentiates it from siblings like ig_publish_photo or ig_publish_reel, which target feed or reels.

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?

Description implies use for Stories but provides no explicit guidance on when to use it versus sibling publish tools (e.g., ig_publish_photo for feed). No prerequisites or required context are mentioned.

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