batch_modify_layer_properties

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

With no annotations provided, the description carries full burden but offers minimal behavioral disclosure. It states this is a modification tool (implying mutation) and mentions performance benefits, but doesn't cover critical aspects like permissions needed, whether changes are reversible, error handling for invalid inputs, or what the tool returns. The performance claim is vague without context.

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, efficient sentence that states the core purpose upfront. There's no wasted language or unnecessary elaboration - every word serves the functional description.

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?

For a mutation tool with no annotations and no output schema, the description is insufficient. It doesn't explain what happens when the tool executes (success/failure responses), doesn't warn about potential side effects, and doesn't provide context about the performance benefits mentioned. The agent would need to guess about behavioral characteristics.

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 fully documents both parameters (compId and modifications array). The description adds no additional parameter semantics beyond what's in the schema - it doesn't explain what 'better performance' means in relation to the parameters or provide usage examples.

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 ('Modify') and resource ('properties of multiple layers'), and specifies the benefit ('for better performance'). However, it doesn't explicitly differentiate from the sibling tool 'modify_layer_properties', which appears to be a single-layer version.

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?

The description provides no guidance on when to use this tool versus alternatives like 'modify_layer_properties' (single-layer) or 'batch_set_expressions'. It mentions 'better performance' as a benefit but doesn't specify thresholds or scenarios where batch operations are preferred.

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