FleetQ

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

Zero annotations provided, so description carries full burden. Fails to disclose security implications (handling raw secrets), what 'rotate' actually does (regenerate vs revoke), atomicity guarantees, or that OAuth operations involve external browser flows. No indication of irreversible operations.

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?

Single dense sentence with zero filler. All content is functional. Could improve readability with line breaks or bullets for 8 distinct actions, but no words are wasted.

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?

Severely lacking for a credential management tool with 15 parameters and no output schema. Missing critical context: security warnings about secret exposure, explanation of pending_review status for agent-created credentials, OAuth correlation flow, and rotation behavior. The schema documents parameters but the description omits workflow and safety 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?

Maps each action to its required parameters in parentheses (e.g., 'create (name, type, secret_data)'), which adds clarity beyond the 100% schema coverage. Helps compensate for the schema's overly broad 'required' array that lists mutually exclusive parameters for different actions.

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?

States 'Manage external service credentials' with clear enumeration of 8 specific actions (list, get, create, update, delete, rotate, oauth_initiate, oauth_finalize). Distinguishes from siblings by specifying 'external service' context, though 'manage' is a weak verb.

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?

Lists available actions but provides no guidance on when to use each, security prerequisites for handling secrets, or the two-step OAuth workflow (initiate vs finalize). No mention of the human approval workflow implied by the agent_id parameter.

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