Record rejected creative direction

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states 'Persist', indicating a write operation, but does not disclose whether it creates or updates records, what happens on repeated calls, whether it overwrites existing feedback, if authorization is required, or what the return value is. This is a significant gap for a state-changing tool.

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 sentence with no filler or repetition. It front-loads the core action ('Persist a rejected direction and the user's reason') and then states the purpose, making it concise and well-structured.

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?

With no output schema, no annotations, a nested fingerprint object, and 7 parameters, the description is too sparse to fully guide an agent. It does not explain how to construct feedback_file, what avoid/preserve mean in practice, or how direction_id relates to fingerprint. An agent would need to infer significant details to invoke the tool 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 coverage is only 14%, so most parameters lack descriptions. The description adds meaning to 'reason' as the user's reason and to 'fingerprint' as the fields for image-making method, composition, palette, and device treatment. However, it does not explain required fields like project_id, direction_id, feedback_file, or the optional avoid/preserve arrays, leaving major gaps in understanding.

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 states a specific verb and resource: 'Persist a rejected direction and the user's reason', and explains the purpose of preventing later iterations from repeating the same method, composition, palette, or device treatment. None of the sibling tools (search_apps, get_app, screenshot tools) overlap with this feedback-recording function, so it is clearly distinguishable.

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 description clearly implies when to use the tool: when a direction is rejected and the user's reason must be recorded to avoid silent repetition in later iterations. It does not explicitly name alternatives or exclusions, but the sibling tools are unrelated, so this contextual guidance is sufficient.

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