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

With no annotations provided, the description carries the full burden. It discloses the tool performs both diagnosis AND repair (a behavioral trait), which implies it can modify instances. However, it lacks details about what 'repairs' entail (e.g., destructive changes, permissions needed, side effects) or response format. The description adds some value but leaves significant behavioral gaps.

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 highly concise and well-structured: two sentences that efficiently convey purpose and usage. The first sentence establishes it as a diagnostic tool with priority guidance, and the second clarifies scope. Every word earns its place with zero waste.

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?

Given the tool has no parameters (simplifying context) but no annotations or output schema, the description is moderately complete. It covers the core purpose and usage but lacks details on what 'diagnoses and repairs' specifically involve, potential impacts, or return values. For a repair tool with no structured safety hints, more behavioral disclosure would be helpful.

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 0 parameters with 100% schema description coverage (empty schema). The description doesn't need to explain parameters, so it appropriately doesn't mention any. A baseline of 4 is applied since no parameters exist, and the description doesn't incorrectly suggest parameters.

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 clearly states the tool's purpose: 'Diagnoses and repairs existing Visum instances' with the specific verb 'diagnoses and repairs' and resource 'existing Visum instances'. It distinguishes from creation tools but doesn't explicitly differentiate from all siblings like 'visum_health_check' or 'project_health_check' which might have overlapping diagnostic functions.

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 provides clear usage context: 'Run this first when encountering errors' and specifies it's for existing instances 'instead of creating new ones'. However, it doesn't explicitly mention when NOT to use it or name specific alternatives among the many sibling tools, such as distinguishing from 'visum_health_check' or 'project_health_check'.

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