add_content_in_library

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

No annotations are provided, so the description carries full responsibility for behavioral disclosure. It only says 'Add a post', which implies a write operation but doesn't mention any side effects, authentication requirements, return values, or the fact that content is queued for future posting. For a tool with 48 parameters, this is a significant transparency gap.

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 a single, concise sentence that front-loads the core purpose. It's efficient with no filler, but it's so brief that it omits important contextual details. The structure is appropriate for the clarity it provides, but the extreme brevity hurts completeness.

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 48 parameters, no output schema, and no annotations, the description is far too minimal. It doesn't explain the workflow (e.g., that content is stored for recurring posting), how to obtain the required library_id (from library_list), the optional workspace_id behavior, or what the response indicates about success. An agent would need to rely entirely on the schema and sibling tools to understand the full context.

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 schema has 100% description coverage for all 48 parameters, each with a clear description. The tool description itself adds no additional meaning beyond what the schema provides. Since the schema already documents parameters well, the description's lack of parameter information is acceptable, though it doesn't add value beyond the schema.

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 action (add a post) and the target resource (content library), and specifies the purpose (recurring/evergreen posting). This distinguishes it from sibling tools like library_list (listing libraries) and post_content (immediate posting), even without naming them.

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 implies the tool is for adding content to a library for later posting, but it doesn't explicitly state when to use this versus alternatives like post_content or generate_content_with_ai. There's no mention of prerequisites such as needing a library_id from library_list, or when to choose this over direct posting. The intent is inferable but not explicit.

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