get_palette

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

No annotations are provided, so the description must disclose behavioral traits. It only states 'Get' which implies a read operation but does not explicitly confirm idempotency, safety, or side effects. It fails to mention any requirements (e.g., active sprite must exist) or limitations.

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 one short sentence of 13 words, which is highly concise. It is front-loaded with the core purpose. However, it sacrifices necessary detail for brevity, particularly regarding the parameter.

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 one required parameter and no output schema, the description is incomplete. It fails to specify the parameter's meaning, the format of the output array, or any error conditions. The agent lacks sufficient information to 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?

The single parameter 'filename' is required but not described at all. The schema has 0% description coverage, and the tool description adds no explanation of what the filename refers to (e.g., sprite file, palette file, output file). The agent cannot understand what value to provide.

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 states the specific action 'Get the active sprite palette' and the return format 'JSON array of hex colors'. It clearly identifies the verb (get) and resource (palette), and differentiates from sibling tools by specifying the active sprite context.

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 offers no guidance on when to use this tool versus alternatives (e.g., set_palette for editing). It does not provide context about prerequisites or conditions, leaving the agent to infer usage from the name alone.

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