art.memory.add_rejection

Log rejected art assets or directions with reasons and status in the art memory, preserving style decisions to prevent repeated mistakes and enforce pixel-art consistency.

Instructions

Add a new rejection record to the art memory.

Behavior2/5

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

No annotations are present, and the description only states the action without disclosing side effects (e.g., whether it validates input, overwrites existing records, or returns a status). The description does not clarify behaviors like conditional requirements.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence that front-loads the purpose and leaves no superfluous words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description lacks essential context such as expected output, error handling, or the conditional requirements implied by the schema (e.g., asset_id required for type=asset). An agent would need to infer these from the schema, making the description insufficient on its own.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema already provides descriptions for each parameter, including constraints and enums. The tool description adds no further semantic clarification about relationships between parameters (e.g., asset_id vs. description depending on type). It relies entirely on the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Add a new rejection record') and the resource ('art memory'), making it distinct from sibling tools like 'find_rejections' or 'add_decision'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no explicit guidance on when to use this tool versus alternatives, such as when a rejection is needed after a QA failure or how it complements the 'find_rejections' tool.

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