tilemap

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It adds the useful detail that each cell becomes a 16x16 tile, but does not disclose side effects, return value, output format, or any constraints beyond the schema.

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 two short sentences with zero wasted words. It front-loads the core purpose and immediately specifies the tile size, making it highly scannable.

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 relatively simple build tool with full schema documentation, the description is adequate but leaves gaps: it does not state what the tool returns, how scale/palette alter the result, or any side effects. Given no output schema and no annotations, a bit more detail would make it complete.

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 already documents all three parameters. The description adds the semantic detail that cells map to 16x16 tiles, which slightly clarifies the grid's role, but lacks deeper explanation of how scale and palette affect the output.

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 builds a tilemap from a 2D grid of tile IDs and specifies the 16x16 cell size. It uses a specific verb and resource, distinguishing it from drawing primitives and other tools, though it does not explicitly contrast with siblings like 'compose' or 'convert.'

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 use when constructing a tilemap from a grid of tile IDs, but provides no explicit guidance on when to prefer this tool over alternatives or any exclusions. No context is given for typical use cases or prerequisites.

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