get_maze

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

No annotations are provided, so the description carries the full burden. It discloses that all bricks are destructible and terrain changes during play, and that border walls are indestructible. It also notes that out-of-range level values are clamped, which is a behavioral trait. However, it doesn't mention the return format or any potential side effects, but given the tool is a read operation, this is adequate.

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 well-structured with a clear opening, a rationale for using the expanded tiles, and a concise Args section. Every sentence adds value, and it's appropriately sized for the tool's complexity.

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 the tool has an output schema (not shown but mentioned), the description doesn't need to explain return values. It covers the key aspects: what the tool returns, why to use it, parameter semantics, and behavioral notes. The description is complete for an agent to select and invoke the tool correctly.

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 0%, so the description must compensate. It explains the 'level' parameter (level number, out-of-range clamped) and 'ascii_map' (include a picture, useful for checking build, set false to save context). This adds meaning beyond the schema's basic types and defaults.

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 tool's purpose: to get a level's brick layout as rectangles and expanded 20x20 tiles. It specifies the resource (level maze) and the action (get), and distinguishes it from siblings by focusing on the brick layout, while siblings like list_sections and get_spec handle other aspects.

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 explicitly advises using the expanded tile list rather than expanding rectangles manually, explaining the risk of subtle differences. It also provides guidance on when to set ascii_map to false to save context, and mentions that border walls are separate and indestructible, which helps the agent understand the tool's output.

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