stop_csv_profiling

End active CSV profiling in Unreal Engine and save the collected data to a file. Use this to conclude performance profiling sessions and export results for analysis.

Instructions

Stop CSV profiling capture and save results.

Input Schema

NameRequiredDescriptionDefault

No arguments

Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the core action (stop and save) but does not reveal side effects, what happens to captured data, whether a running session is required, or any error cases. This is minimal disclosure for a state-changing operation.

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, efficient sentence with no filler. It conveys the primary action and the secondary save behavior without redundancy, earning a perfect conciseness score.

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

Completeness3/5

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

For a zero-param tool with no output schema or annotations, the description covers the basic action but misses contextual details such as requiring an active profiling session, what 'save results' means in terms of file location or format, and any return value. The pairing with start_csv_profiling is only evident through the sibling list, not the description itself.

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

Parameters4/5

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

The input schema has zero parameters, and the baseline for 0-param tools is 4. The description adds no parameter-specific information, but none is needed since there are no parameters to clarify.

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 tool stops CSV profiling capture and saves results, using a specific verb and resource. It distinguishes from the sibling tool 'start_csv_profiling' by explicitly mentioning the stopping and saving behavior.

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. It does not mention that it should be used after start_csv_profiling or describe any preconditions, making the usage context entirely implied by the tool name.

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