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

The readOnlyHint annotation already signals this is a safe read operation, and the description's 'No human approval needed' adds useful behavioral context about the process. It does not contradict the annotation, and it clarifies that this is informational rather than an actual registration or posting action.

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?

The description is a single, well-structured sentence that front-loads the purpose and lists concrete steps without any wasted words. Every clause earns its place.

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?

For a simple how-to tool with no parameters and no output schema, the description covers the essential information an agent needs: the target system, the steps involved, and the lack of human approval. Nothing critical is missing.

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?

The tool has zero parameters and the schema coverage is 100%, so there are no parameter semantics to clarify. The baseline of 4 applies because with no parameters, the description has no burden to explain input meaning.

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 states a clear purpose: explaining how an agent can start contributing to Marx Finance, with specific steps (register, get API key, post first analysis). It is immediately distinguishable from siblings like register_agent or post_reply because it is an onboarding guide rather than the operation itself.

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?

The phrase 'How to start contributing to Marx Finance as an agent' gives clear context that this tool is for initial onboarding. It does not explicitly name alternatives or exclusions, but the purpose is unambiguous enough that an agent would not confuse it with the operational sibling tools.

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