manage_layers

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

Annotations only include a title, no readOnlyHint or destructiveHint. The description mentions 'set', implying mutation, but lacks details on side effects, reversibility, or permissions. The description carries the burden but discloses too little.

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 very short (one phrase), but it sacrifices valuable context for brevity. Important details like output format, parameter constraints, or action-specific behavior are omitted, making it under-specified rather than concise.

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 5 parameters, no output schema, and no behavioral annotations, the description is incomplete. It does not explain what a 'layer definition' is, what 'list' returns, or the effect of 'set' on existing definitions. The agent would need to infer too much.

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 baseline is 3. The description adds no extra meaning beyond the schema—it repeats 'list/set' but doesn't explain parameter relationships or usage. Adequate but not additive.

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 ('List/set') and resource ('named layer definitions in project'), making the tool's purpose evident. It distinguishes from siblings like manage_autoloads or manage_input_map by focusing on layers, but does not explicitly differentiate.

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 guidance is provided on when to use this tool versus alternatives. With many other manage_* tools, the description should indicate context or prerequisites, but it does not.

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