apply_enhancement_plan

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

With no annotations, the description must disclose side effects itself. It does usefully state that the tool is deterministic, creates a new output file, and preserves the source asset. However, it does not explain what happens if the output file exists, whether the plan is provided as a parameter or referenced elsewhere, or what the tool returns on success or failure.

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 a single tight sentence with no filler, and the most important behavioral facts are front-loaded. It loses a point only because it omits enough substantive detail that the conciseness comes at the cost of usefulness.

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?

This is a 6-parameter tool with no output schema and no annotations, yet the description does not explain what an enhancement plan is, where it comes from, or how the parameters influence the result. The minimal 'new output file while preserving source' context is helpful but far from sufficient for correct invocation.

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 adds no parameter-level meaning. It does not clarify that filename is likely the source asset, output_filename is the new file, or what goals, seed, max_colors, and format control. The enum values for goals are left entirely unexplained.

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 a concrete action ('Apply'), a specific resource ('enhancement plan'), and the target behavior ('to a new output file while preserving the source asset'). This clearly distinguishes it from the sibling apply_enhancement_batch, which operates on multiple items, and from suggest_enhancement_plan, which only creates a plan.

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 explicit guidance about when to use this tool versus suggest_enhancement_plan or apply_enhancement_batch. The phrase 'deterministic enhancement plan' implies a prior plan exists, but the description never states that precondition or any alternative-selection condition.

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