Post to a connected account

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

No annotations are provided, so the description must convey behavioral traits. It states 'Publish a post' implying a write operation, but does not disclose aspects like whether the operation is synchronous, error handling, rate limits, or permissions needed. The minimal disclosure leaves the agent with uncertainties.

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 two sentences long, front-loading the core action and immediately following with optional parameters and targeting rules. Every word contributes meaning, with no redundancy or filler.

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 tool has 5 parameters (one required), no output schema, and no annotations, the description covers the basics of usage but lacks information about the return value or error scenarios. It is adequate for a standard tool but could be improved with a brief note on what the response looks like.

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 coverage is 100% with well-described parameters. The description adds value by explaining how to use 'platform' versus 'account_id' and gives concrete examples for 'settings' (e.g., reddit {subreddit, title}), which goes beyond the schema's definition.

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 'Publish a post to a connected account' with specific verb and resource. It also differentiates from sibling tools (connect_account, get_analytics, list_accounts, list_platforms) which are not posting tools. Additional details like media and per-platform settings further clarify scope.

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 provides guidance on targeting an account by account_id or by platform when only one account is connected. It also gives an example of per-platform settings with reddit {subreddit, title}. However, it does not explicitly exclude scenarios or mention alternatives beyond the given options.

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