open_layoutpilot

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

No annotations are provided, so the description carries full burden. It states the primary action (open in browser) and the optional prompt behavior. However, it doesn't disclose what happens after opening — does it return navigation info? Does it fail if browser unavailable? What does 'open' return? Some behavioral context is missing for an unannotated tool.

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?

Two concise sentences, zero waste. Every word earns its place: primary action stated first, optional behavior second. Clean and front-loaded.

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?

This is a simple tool — one optional param, no output schema, no nested objects. Given the low complexity, the description is reasonably complete for its scope. However, it doesn't clarify its relationship to the sibling generation tools (generate_ui, generate_component), which could help an agent decide whether to open LayoutPilot or call the generation tools directly.

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% — the single 'prompt' param is described in both the schema ('Optional prompt to pre-fill in LayoutPilot') and the description ('Optionally provide a prompt to pre-fill the input field'). The description adds minimal value beyond schema, essentially restating it. Baseline 3 is appropriate since schema does the heavy lifting.

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?

Clear verb+resource: 'Open LayoutPilot in the browser.' Names the tool explicitly and states a specific action (open in browser). The optional prompt pre-fill detail adds secondary functionality. However, it doesn't distinguish from siblings (generate_ui, generate_component) — the 'opening' action vs 'generating' action is implied but not contrasted.

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 implies this opens LayoutPilot as opposed to generating output directly, which distinguishes it contextually from siblings. But there's no explicit when-to-use vs when-not-to-use guidance, no mention of prerequisites (e.g., browser availability), and no alternatives named. Usage is implied rather than stated.

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