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 two genuinely useful traits: the result is deterministic code-based rules (not AI) and each call costs $0.02 USD via x402, which signals a paid endpoint the agent should not call casually. It says nothing about whether the tool is read-only, what the response contains, or how failures/insufficient data are handled.

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?

It is short, but the first two sentences are redundant restatements of the same idea (Ruta Mipyme / ruta para crear una mipyme). The cost and no-AI facts earn their place; the duplication does not.

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 31-parameter, no-annotation, no-output-schema tool, the description is too thin: it never explains what the response looks like (route/steps/requirements), nor how to call it with a partial set of inputs. An agent can identify the topic but cannot predict the outcome of a call.

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 31 parameters are already documented field by field. The description adds no semantics beyond the schema – notably it never mentions the ciiu-vs-descripcion alternative or the minimal viable input set, which is the main thing an agent would need to know given all parameters are optional.

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 names a verb-like function ("guía/orientar") and a resource (creating a mipyme in Colombia), and adds that it is rule-based (R1–R8, no AI). But "orientar/guía" is vague about what the agent actually gets back – a step-by-step route, a diagnosis, a checklist of obligations – so it does not fully distinguish itself from siblings like 'registro_marca__ruta' or 'ruta_tac__revisar'.

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 the other ruta/consultar tools, and no guidance about prerequisites or what a user must supply first. The reader must infer the use case entirely from the title-ish first sentence.

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