light_set_shadow

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

With no annotations, the description must fully disclose behavior, but it lacks details on side effects (e.g., whether it modifies existing light or creates something), what happens if light doesn't exist, persistence, or return value structure beyond 'success message or error description'.

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?

Description is relatively short and front-loaded with the main purpose. Includes a category line and arg list. Could be more concise but no wasted sentences.

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 6 parameters and output schema exists, description covers basic purpose and parameter list but lacks behavioral details and return format explanation. Adequate but not fully self-contained.

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 0%, so description compensates by listing parameters with brief explanations. However, it omits units, ranges, or value guidance for 'shadow_bias' and 'shadow_blur', and does not clarify the paths format. Adds some meaning but not comprehensive.

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 configures shadow settings for a light source, using specific verb 'configure' and resource 'shadow settings for a light source'. It distinguishes from sibling tools like 'light_set_properties' which handle general light properties.

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 explicit guidance on when to use this tool versus alternatives like 'light_set_properties' or 'light_add'. No prerequisites, when-not-to-use, or scenarios mentioned.

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