create_service

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

Annotations are absent, so the description carries the full burden of behavioral disclosure. It only states that it creates a service and notes prices are in RUBLES. There is no mention of side effects, required permissions, reversibility, or response characteristics. This is insufficient for a creation operation.

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 very concise with two short sentences, no fluff, and front-loaded with the primary action. However, the second sentence about RUBLES is largely redundant given the schema's field description, slightly reducing its earned value.

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 a creation tool with six parameters, no output schema, and no annotations, the description is extremely minimal. It does not explain what constitutes a 'service' in this domain, how it relates to products, or any business rules. More context is needed for an agent to use it correctly.

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 documents all six parameters. The description adds a minor emphasis on currency (RUBLES), which is already stated in the sale_price_rubles property description. This adds little value beyond the schema, matching the baseline of 3 for high coverage.

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 'Create a service,' which is a specific verb plus resource. However, it does not differentiate from the sibling tool create_product, which likely has overlapping functionality. The phrase 'Prices in RUBLES' hints at a key constraint but doesn't distinguish the service context.

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?

No guidance is provided on when to use this tool versus alternatives like create_product or update_prices. There is no mention of prerequisites, use cases, or exclusions. The description simply states what the tool does without contextualizing when it should be chosen.

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