v1.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries full burden, yet it discloses no behavioral traits. It does not indicate whether the update is full replacement or partial (PATCH vs PUT), what happens to unspecified fields, or if the object must exist beforehand.
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 sentence, which is concise but lacks structure. It does not waste words, but it is underinformative, missing important details given the tool's complexity.
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 no output schema, no annotations, and nested objects, the description is incomplete. It fails to explain field constraints, update semantics, or how to correctly construct the body, leaving the agent underinformed.
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 50%; uuid lacks description, body description is generic ('JSON request body matching the target Security Director Cloud schema'). The description adds minimal value beyond the schema, not explaining body structure or constraints.
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 'Update a variable zone object by UUID', which is a specific verb+resource combination. It distinguishes from sibling CRUD tools like create, get, delete, and list. However, it lacks context on what a variable zone is, but the name implies the resource type.
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 vs alternatives (e.g., when to update vs create). No prerequisites, idempotency, or partial update behavior mentioned. The description provides no usage context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
