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

No annotations exist, so the description carries the full burden. It discloses global scope ('entire composite') but nothing about whether the operation is destructive, applies to a layer or the merged result, respects selections, or can be undone. For a mutation tool with zero annotation coverage this is a significant gap.

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?

A single front-loaded sentence with no filler or redundancy. It is efficient, though its brevity is partly under-specification rather than disciplined concision.

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?

An output schema exists, so return values are covered, but with no annotations, undocumented parameters, and no usage context, the definition leaves the agent short of what it needs to invoke this tool confidently.

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% for all three parameters. The description's mention of 'contrast' and 'color vibrance' loosely hints at contrast_amount and saturation_boost but gives no ranges, units, or defaults, and target_mood (with its default of 'vibrant_daylight') is never referenced at all.

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 (harmonizes) and the resources it affects (lighting, contrast, color vibrance) with an explicit scope of 'the entire composite'. This distinguishes it reasonably from per-channel siblings like adjust_brightness_contrast, though it never names those alternatives.

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 when-to-use guidance, no prerequisites, and no mention of when this should be preferred over adjust_brightness_contrast, auto_contrast, auto_levels, or harmonize_sky. The agent must 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.
