get_current_active_look

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

No annotations exist, so the description carries the full behavioral burden, but the tool is a zero-argument read, so little needs disclosing. 'If any' is a genuinely useful signal that the result may be empty or null. It still says nothing about auth requirements or what an 'active look' object contains.

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?

One short sentence with zero filler, and the qualifier that matters most ('currently active', 'if any') is front-loaded. Nothing could be removed without losing information.

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 zero-param, no-output-schema tool the definition is minimally sufficient, but it leaves the return shape unexplained and never defines what makes a look 'active' versus merely existing or being on a look board. With almost no structured context to lean on, a sentence or two more would materially help.

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 tool takes no parameters, so the baseline for parameter semantics is 4. The description correctly implies parameterless operation and adds no misleading argument hints.

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?

States a specific verb and resource ('get the currently active look'), which is more precise than a bare 'get look' because it names the state being queried. However, it never distinguishes itself from close siblings like get_look, list_looks, or activate_look, so an agent must infer the difference.

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 phrasing 'if any' implies this is a non-destructive status query that may return nothing, which hints at when it applies. There is no explicit when-to-use statement, no exclusions, and no pointer to alternatives such as get_look or list_looks for the non-active case.

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