Account and server status

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

Annotations already establish readOnly, idempotent, openWorld, and non-destructive behavior, so the bar is lower; the description still adds meaningful context by disclosing that the result includes credential provenance and remaining Admin API quota, hinting at a live account-level call. It stops short of saying whether the call itself consumes quota or requires specific credentials.

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?

One sentence, front-loaded with the resource, and no filler. The parenthetical list of returned fields is dense but every item is informative; the only nit is the clipped, verb-less phrasing.

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?

With zero parameters, full annotation coverage, and a dedicated output schema, the description needn't explain return structure and wisely doesn't. The remaining gap is the absence of any routing guidance against the closely named cloudinary_info sibling and no note on quota cost or auth requirements.

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?

Zero parameters, so there is nothing for the description to disambiguate; baseline is 4. The description correctly adds no parameter chatter and instead spends its words on returned content.

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 enumerates exactly what the tool returns: cloud name, folder mode, credential source, remaining Admin API requests, and safety settings. That makes the resource specific enough to distinguish it from most siblings, but it never states a verb or explicitly contrasts with cloudinary_info, the one sibling an agent could plausibly confuse it with.

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?

Use is implied rather than stated: an agent can infer this is the place to check account identity, credential origin, or quota headroom, but the description never says when to call it, when not to, or why to prefer it over cloudinary_info. No alternatives or prerequisites are named.

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