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

Annotations are all false (non-informative), leaving the description as the sole source of behavioral disclosure. The description gives no indication of what gets created, idempotency semantics, content size limits, auth/permission requirements, or response behavior. It adds no behavioral context beyond the raw endpoint path.

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 token with no wasted words, but this is gross under-specification rather than crafted conciseness. There is no information that earns its place because there is effectively no information at all.

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 a nested body object, three parameters, an output schema, and many closely related siblings, this description is radically inadequate. An agent cannot determine what the tool does, when to call it, or what it returns. Nothing needed for correct invocation is provided.

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 67%, with workspaceId and idempotencyKey documented in-schema while the body object — the core payload — is not described, and neither are its properties (title, contentType, sizeBytes). The description 'POST /v1/media' adds nothing about parameters or their meaning, failing to compensate for the undocumented body.

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 'POST /v1/media' merely restates the endpoint as the HTTP verb plus resource path, essentially echoing the tool name. It provides no semantic meaning about what 'media' is, whether this creates or uploads content, or how it differs from sibling tools like post_media_id_complete and post_posts. This is close to a tautology.

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 guidance on when to use this tool versus alternatives such as put_posts_id_content_channelId_media or post_media_id_complete. No context about prerequisites, sequencing, or exclusions is provided; the description carries zero usage direction.

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