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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds content-scope information (the workflow spans inquiry through collection), but says nothing about what an unknown or unsupported profession returns, whether the lookup is exact-match or fuzzy, or how many stages are typically produced.

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 purpose is front-loaded in the first clause and reinforced by a concise English restatement. However, the parenthetical enumeration of roughly fourteen professions is long and largely duplicates the examples already present in the schema parameter description, so it does not fully earn its space.

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 one-parameter read-only lookup this is close to adequate, and annotations carry the safety contract. But with no output schema, the description should say what the response looks like (a list of stages/steps, keyed by profession) and how unknown professions are handled; that gap leaves an agent unable to anticipate the return value.

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 the parameter already documents accepted forms ("spa", "nha khoa", "nha-phan-phoi-dai-ly"). The description's broader profession list adds some vocabulary beyond the schema examples, but no new syntax, mapping, or matching rules — baseline 3 applies.

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 concrete resource — a step-by-step operating workflow for a specific profession, framed end-to-end 'from customer inquiry to cash collection' — and enumerates the supported professions (spa, nha khoa, agency, xưởng may...). An agent can tell this is a workflow lookup rather than a pricing or quoting tool, though no sibling is named explicitly.

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?

Usage is only implied by the purpose: call it when you need the operating process for a given profession. There is no explicit when-to-use vs. when-not guidance and no pointer to alternatives such as about_sulato_business, so the agent must infer the boundary itself.

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