Changes observed during successful MCP inspections.
v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry full behavioral context. It states the action but fails to disclose side effects, permissions, return values, idempotency, or constraints. The description is too brief for a mutation 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 a single, efficient sentence with no superfluous information. Every word serves a purpose, making it ideal for quick comprehension.
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 creation tool with an open schema and no output schema, the description covers the primary action and typical body fields but omits details on return values, success/failure behavior, or prerequisites. It is minimally adequate but incomplete.
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% with a vague parameter description. The tool description adds value by listing typical fields (name, description, type, default_zone) that the body should contain, compensating for the schema's lack of clarity.
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 new variable zone object.' with a specific verb and resource. It distinguishes from siblings like list, get, update, delete by indicating creation. The mention of typical body fields adds specificity.
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 verb 'Create' makes the primary usage clear but does not explicitly state when not to use (e.g., for modifications) or provide alternative tool names. However, the context of CRUD siblings implicitly conveys the appropriate usage scenario.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
