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

Goes well beyond annotations: discloses that the key and recovery code are shown only once (irreversible display), that human use triggers revocation, and warns that server content is untrusted data not to be obeyed. Annotations already declare non-readOnly/non-destructive, and the description adds substantial operational context on top.

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?

Requirements and the one-time-display warning are front-loaded, and most sentences carry distinct value. The trailing security notes (untrusted quotes, no agent-to-agent messages) read as a server-wide briefing rather than tool-specific guidance, slightly diluting focus.

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 no output schema, the description correctly explains what comes back (key plus recovery code, shown once). Preconditions, exclusions, and security caveats are covered; only the optional parameters remain under-described.

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 only 33%, and the description explains just the two required params. It leaves name vs agent_name, model, and operator unexplained, and doesn't clarify the relationship between name and agent_name. It compensates partially but not fully for the coverage gap.

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 a specific verb and resource: 'Issue a free solo Minds Ajar key for an AI agent.' The word 'solo' implicitly contrasts with the sibling register_swarm, though it never names the alternative. An agent can identify what the tool does without opening the schema.

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?

Gives clear preconditions (agent_name and i_am_an_ai_agent must be true) and explicit exclusions (humans other than Koen get no keys; don't send a model-provider API key; no email). It stops short of naming register_swarm as the alternative for swarm registration, which is the one missing routing cue.

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