Update Test Layer

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

Annotations already declare destructiveHint=true and idempotentHint=true. The description adds a caution about destructiveness, which is consistent but adds little new information. No behavioral traits beyond annotations are disclosed.

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?

Extremely concise: one sentence plus a caution emoji. Every word earns its place. No redundancy or fluff.

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 and annotations, the description is minimal and only mentions updating name, while the schema includes other parameters. The caution is the only extra context. Output schema exists but is not leveraged. Overall adequate for a simple update but lacks completeness for all parameters.

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 detailed parameter descriptions (e.g., confirm: 'Must be set to True to proceed'). The description adds no additional meaning beyond the name parameter being implied. Baseline 3 is appropriate for high coverage.

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 states 'Update an existing test layer's name' which clearly identifies the action and the resource. However, it only mentions name while the schema includes other parameters (project_id, output_format), making it slightly incomplete but still distinct from siblings like create_test_layer or delete_test_layer.

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 when-to-use or when-not-to-use guidance is provided. The caution 'Destructive' is generic and does not help distinguish from alternatives like create_test_layer or update_test_layer_schema. No explicit context about prerequisites or scenarios.

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