find_by_code

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

Discloses that it returns data or a not-found message, but with no annotations, the description should provide more detail on side effects (none expected), error conditions, or performance. Adequate for a simple read operation but could be more explicit.

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 concise sentences with no redundant information. Every word adds 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?

For a simple lookup tool, the description covers the basic purpose and return type. However, lacking output schema, it does not describe the structure of returned data, which may be needed for effective use.

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 coverage is 100% so the description adds no extra meaning beyond the field titles and descriptions already in the schema. No additional semantic guidance is provided.

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 clearly states the action 'Найти объект по коду' (find object by code) and the return behavior, distinguishing it from siblings like find_by_name by specifying the search criterion (code). However, it does not explicitly differentiate from other search methods.

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 on when to use this tool versus alternatives such as find_by_name or other lookup tools. Lacks explicit usage context or prerequisites.

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