scopes

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

No annotations are provided, so the description carries the full behavioral burden. It hints at analysis (suggesting read-only) by naming measurement capabilities, but never states side effects, whether any of the 12 actions mutate state, permission requirements, or output behavior.

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?

It is short and front-loads the domain, which is good. But the trailing ellipsis and bracketed '[12 actions]' placeholder are cryptic filler that do not earn their place by conveying actionable detail.

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 multi-action tool (12 actions), with a required enum-like 'action' string, a nested 'args' object, 0% schema coverage, no annotations, and no output schema, this description is grossly inadequate. It omits the action list, argument shapes, and return behavior an agent needs to invoke it 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% and the description provides no parameter information at all. The '[12 actions]' placeholder hints that the required 'action' string has twelve possible values, yet none are listed, and the nested 'args' object is entirely unexplained, so an agent cannot construct a valid call.

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 names the resource domain (scopes/measurement) and lists example capabilities (waveform/vectorscope, exposure, false color, gamut), which distinguishes it somewhat from siblings like color_grade. However, it is a noun-phrase label with no explicit verb and never states what the tool actually does (return measurements? apply corrections?), so the purpose is only implied.

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?

There is no when-to-use guidance, no exclusions, and no mention of alternatives such as color_grade or color_science, which plausibly overlap. The agent must infer usage from the domain name alone.

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