writeback_apply

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

With no annotations, the description carries the full burden of behavioral disclosure. It usefully states that existing files are never overwritten, but it does not explain whether writes are reversible, how undo_action relates, whether the operation is idempotent, or what happens to files already partially present.

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 front-loaded sentence with no filler. The safety-relevant parenthetical is attached directly to the action it modifies, making it easy to scan.

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 mutation tool with no annotations, no output schema, and zero schema description coverage. The description omits the preview/undo workflow, project defaulting behavior, asset ID semantics, and any notion of what the write produces, leaving too much for an agent to infer.

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%, so the description must compensate for both parameters, but it barely does so. 'Staged assets' hints at asset_ids and 'game project' hints at project, yet it gives no format, default behavior, or selection semantics for either parameter.

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 action and target: writing staged assets and engine glue stubs into the game project. It is clear what the tool does, but it does not differentiate itself from the sibling writeback_preview tool, which an agent might reasonably confuse with an apply step.

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 on when to use this tool versus writeback_preview, undo_action, or other write-oriented siblings. The only contextual hint is the parenthetical about not overwriting existing files, which describes behavior rather than usage conditions or prerequisites.

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