create_subscription

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

No annotations are provided, and the description only states 'create' (implying mutation) without disclosing behavioral traits like authentication requirements, rate limits, side effects, or response behavior. Minimal transparency.

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?

One short sentence with key information; no wasted words. However, could include a bit more detail (like spec requirements) without harming conciseness.

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 the complexity (nested spec parameter, low schema coverage), the description is insufficient. It omits details on parameter semantics, return value (output schema exists but not described), and behavioral context. Incomplete for a tool with nested objects.

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 0%, so the description must compensate, but it only lists transport types, not explaining the spec parameter structure, required fields (e.g., endpoint, event_types), or semantics. Barely adds value beyond field names.

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 verb 'Create' and the resource 'lzt-eventus subscription', and lists the supported transport types (webhook/websocket/sse/polling), distinguishing it from sibling tools like list_subscriptions or poll_pending_events.

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 explicit guidance on when to use this tool vs alternatives (e.g., not mentioning prerequisites or scenarios). The purpose is implied by the verb, but no exclusions or context provided.

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