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

With no annotations, the description carries the full burden. It does disclose a genuinely non-obvious side effect — self-initialization of a 0-sat scaffold when no model exists — which is valuable behavioral context for a read-shaped call. But it omits auth/permission requirements, rate limits, and whether the self-init is persisted. This is a substantial gap given zero annotation coverage, though the side-effect disclosure keeps it above the midpoint.

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?

Short and front-loaded: the core purpose leads, with the fallback behavior second. 'No economic data from code' is a slightly cryptic trailing clause, but nothing is wasteful.

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?

An output schema exists, so return values need not be explained, and there are no parameters. The description covers the key non-obvious behavior (self-init scaffold). Missing only the auth/permission context, which leaves a small gap rather than a critical one.

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?

Zero parameters, and the schema has no properties, so the baseline is 4. There is nothing for the description to clarify beyond what the empty schema already implies.

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+resource: 'Get the active pricing model for this operator.' An agent can tell it is a read of pricing config, distinct from set_pricing_model/reset_pricing_model. However, it never names those siblings, so the differentiation is implicit rather than stated.

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?

No when-to-use guidance at all. It does not say to call this before set_pricing_model, nor when a fresh scaffold is expected vs. an existing model. 'Free' hints at cost but gives no selection context against the sibling pricing tools.

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