ig_publish_video

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

With no annotations, the description carries the full burden. It mentions 'Two-step process' but doesn't explain what the steps are, prerequisites, side effects, or required confirmation. The 'confirm' parameter and its purpose are not disclosed. Minimal behavioral insight is provided.

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 short and to the point, but the 'Args:' section is incomplete and somewhat disorganized. It wastes no words but fails to provide enough structure or clarity, making it under-specified rather than concise.

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 six parameters, no output schema, and no annotations, the description is highly inadequate. It doesn't explain the two-step process, return values, confirmation behavior, or any prerequisites. This is a publish action with potential side effects that needs more context to be safely used.

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 0%, so the description must compensate. It only mentions media_type with allowed values, but not its meaning. The other five parameters (ig_account_id, video_url, caption, cover_url, confirm) are completely unexplained. The 'Args:' section is misleading as it lists only one parameter.

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 tool 'Publish a video/reel to IG', which is a specific verb+resource action. It distinguishes from siblings like ig_publish_image by indicating video/reel, though it doesn't explicitly compare to other publish tools. The 'Two-step process' adds a bit of context about the operation.

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?

There is no explicit guidance on when to use this tool versus alternatives. The description does not mention ig_publish_image for images or any exclusions. The 'REELS (recommended)' note is parameter advice, not usage context. Usage is only implied by the tool name and description.

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