moltbook_register_agent

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

No annotations are provided, so the description carries the full burden, but it does add useful behavioral context by naming the outputs (API Key and Claim URL). It still omits duplicate-name handling, idempotency, auth requirements, and whether registration can be repeated.

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?

Two short sentences, zero filler, with the action stated first and the return values second. Nothing needs trimming or moving.

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 discloses return values, which is the minimum needed for a registration tool with a fully documented schema. However, it says nothing about what the Claim URL is for or what happens after registration, leaving the onboarding workflow partly unexplained.

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% and both parameters are documented in the schema, so the baseline of 3 applies. The description adds no meaning about the 'name' or 'description' fields beyond what the schema already states.

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 gives a specific verb and resource ('Register a new agent') and clearly separates this onboarding tool from feed/post/comment siblings. It does not distinguish itself from the similarly named craber_register sibling, which is the only real ambiguity.

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 statement of when to call this versus alternatives, and no mention of prerequisites (e.g., needing a name and description, one-time onboarding, pairing with moltbook_save_credentials). The reader must infer the when from the purpose alone.

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