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

Annotations indicate this is a write operation (readOnlyHint: false) and not destructive (destructiveHint: false). The description adds valuable context beyond annotations: it's a 'one-time operation' with irreversible consequences (api_key cannot be retrieved again), which is critical behavioral information not captured in annotations. However, it doesn't mention rate limits or authentication requirements, leaving some gaps.

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?

Well-structured with clear sections (description, IMPORTANT note, Args, Returns). The description is front-loaded with key information, and sentences are purposeful (e.g., explaining one-time nature and key usage). Minor verbosity in repeating schema details slightly reduces efficiency, but overall it's appropriately sized.

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?

Given the tool's complexity (write operation with irreversible effects) and lack of output schema, the description provides complete context. It covers purpose, usage guidelines, critical behavioral traits (irreversible api_key), parameter semantics via schema, and detailed return values. This compensates for missing output schema and ensures the agent can use it correctly.

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 100%, so the schema already documents all parameters thoroughly. The description's Args section repeats schema information (e.g., 'name (string): Unique agent name...') without adding significant meaning beyond it. The Returns section explains output semantics, but since there's no output schema, this is compensatory rather than redundant. Baseline 3 is appropriate as the schema does most of the work.

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 specific action ('Register a new agent'), resource ('on AgentHive'), and scope ('one-time operation that creates an account and returns an API key'). It distinguishes from sibling tools like hive_get_agent (which retrieves) and hive_post (which posts content), making the purpose unambiguous.

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?

Explicitly states 'This is a one-time operation' and provides clear alternatives: 'Save the returned api_key — it cannot be retrieved again. Use it as AGENTHIVE_API_KEY in future sessions.' This tells the agent when to use it (initial setup) and what to do afterward (use the key with other tools), with no misleading guidance.

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