Update Test Layer Schema

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

Annotations already provide destructiveHint=true and idempotentHint=true. The description adds '⚠️ CAUTION: Destructive' which reinforces the destructive nature but does not add substantial behavioral context beyond annotations. Idempotency is not mentioned.

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?

Very concise: two short lines. Front-loaded with the action and a clear caution. No redundant information. Every part earns its place.

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?

Despite high schema coverage, the description lacks crucial context: the confirm parameter requirement (must be true) is only in the schema. For a destructive update, more guidance on consequences and process would improve completeness. No output schema exists, so return behavior is unclear.

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 baseline is 3. The description does not elaborate on any parameter. It only states the tool's general purpose. The schema itself fully describes parameters, so description adds no extra semantics.

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 'Update an existing test layer schema' with a specific verb and resource. It distinguishes from sibling tools like create, delete, and list. The title matches. The caution adds emphasis but purpose is unambiguous.

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 versus alternatives like create_test_layer_schema or delete_test_layer_schema. The description implies usage for updating an existing schema, but lacks context on prerequisites or scenarios where other tools are more appropriate.

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