Validate license

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

Annotations already declare readOnly/idempotent/non-destructive, so the bar is lower, yet the description adds real behavioral context: it requires the private profile credential, explicitly has no global API-key fallback, and keeps customer metadata private. This auth/privacy disclosure goes beyond what the annotations provide.

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?

At two short sentences it is compact with no obvious padding. However, the phrasing is awkward and garbled ("for native validate license"), which slightly obscures the front-loaded purpose.

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?

With 100% schema coverage, no required params, and no output schema, the description covers the auth/privacy angle adequately. It is only minimally viable though: it never indicates what a validation result conveys (valid/invalid), which is the natural question for a read-only validator with no output schema.

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 already documents account, payload, instance_id, and payload_file fully. The description adds no additional parameter semantics beyond the schema's own note that the license credential is never body input, so the baseline 3 is appropriate.

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 states a verb+resource ("validate license") but it essentially restates the tool name, making it close to tautological. It adds the credential mechanism ("selected private profile license credential") but never clarifies what validation means or how it differs from siblings like activate_license or deactivate_license.

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?

It implies the usage context (invoke under the selected private profile) and gives a constraint ("No global API-key fallback"), which is useful guidance. However, it never states when to use this versus the adjacent license tools (activate/deactivate/list), leaving the routing decision to inference.

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