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

There are no annotations, so the description carries the behavioral transparency burden. It discloses the return format (0-100 score, main risk drivers, recommendation) and names the three possible recommendation categories. It does not disclose how missing optional parameters are handled, but it clearly presents the tool as a non-mutating scoring function.

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 sentences with no filler. The purpose is front-loaded, and the second sentence delivers the essential return-value details. 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?

No output schema exists, so the description correctly explains what will be returned, including the specific recommendation categories. With seven parameters, the schema covers their semantics, and the description covers the tool's overall behavior. It could have added guidance on how omitting optional parameters affects the score, but this is not a critical gap.

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 all seven parameters are documented structurally. The description adds no extra parameter-level detail beyond mentioning 'a short description of its situation', which is somewhat misleading since the inputs are structured enum fields rather than free-form text.

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?

Description states a specific verb ('Score') and resource ('structural risk of a company's current ERP'), and ties it to Bramvia's ERP Health Check concept. The output description (0-100 score, risk drivers, recommendation) makes it distinct from siblings like estimate_migration and check_compliance_deadlines.

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 description implies the use case: assess structural risk from a short ERP situation description. However, it does not explicitly state when to prefer this tool over siblings such as estimate_migration, check_nav_support_status, or find_profit_leaks, and offers no exclusion guidance.

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