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

With no annotations provided, the description carries full burden for behavioral disclosure. It mentions using 'verified Visum API' and a specific method discovered on a date, but doesn't disclose critical behavioral traits: whether this is a mutation (likely yes, but not stated), what permissions are needed, whether it's idempotent, what happens on failure, or what the response contains. The API method detail is technical but doesn't help the agent understand behavioral implications.

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 reasonably concise (two sentences) but includes unnecessary technical details ('visum.Procedures.Operations.AddOperation() method discovered on 2025-10-10') that don't help an AI agent select or invoke the tool. The emoji adds visual emphasis but no semantic value. The first sentence is front-loaded with the core purpose, but the second sentence doesn't earn its place for agent decision-making.

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 mutation tool with no annotations and no output schema, the description is incomplete. It doesn't explain what happens after creation (does it return a procedure ID? status?), error conditions, or integration with sibling tools. The technical API details don't compensate for missing behavioral context needed for safe and effective tool invocation.

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 schema already documents all parameters thoroughly. The description adds no additional parameter semantics beyond what's in the schema - it doesn't explain relationships between parameters, provide examples of valid 'parameters' object contents, or clarify edge cases. Baseline 3 is appropriate when schema does the heavy lifting.

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 creates a Visum procedure, specifying the action (create) and resource (Visum procedure). It distinguishes from siblings by focusing on procedure creation rather than project management or analysis tasks. However, it doesn't explicitly differentiate from potential similar creation tools that might exist.

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 no guidance on when to use this tool versus alternatives. While it mentions specific procedure types (PrT Assignment, PuT Assignment, etc.), it doesn't explain when to create a procedure versus using other tools like visum_check_assignment or visum_network_analysis. No prerequisites, exclusions, or alternative scenarios are mentioned.

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