instagram_post_video

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

No annotations provided, so the description bears full responsibility. It does not disclose behavioral traits such as whether comments are disabled by default, any auth requirements, rate limits, or side effects. Only states the action without operational details.

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?

Concise: one sentence for purpose, then a clear list of parameters. No unnecessary information. Front-loaded with main action.

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 existence of an output schema (not shown), return values are not needed. The description covers the action and parameters adequately. However, it lacks behavioral context (e.g., prerequisites, side effects) that would help the agent decide confidently. For a mutation tool with 8 parameters, it is minimally complete but has gaps.

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%, but the description compensates by listing each parameter with a brief explanation (e.g., 'Local path or URL to MP4 file', 'Comma-separated hashtags'). This adds meaning beyond the schema types. However, could be more detailed (e.g., character limits, accepted formats).

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?

Clearly states 'Post a video to the feed with full caption control', specifying the action (post) and resource (video to feed). Distinguishes from photo, reel, album, and story posts by mentioning 'feed'. However, it does not explicitly differentiate from instagram_post_video_story, which also posts a video but to stories.

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 guidance on when to use this tool versus alternatives like instagram_post_reel or instagram_post_video_story. No usage context or prerequisites (e.g., login required) are mentioned.

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