set_niagara_playback_range

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

No annotations are provided, so the description carries full burden. It states that the tool sets playback range but does not disclose side effects (e.g., persistence, permissions, or what happens if parameters are out of bounds). The behavioral impact is insufficiently explained for safe use.

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 concise with a clear front-loaded purpose statement, followed by practical usage hints and a structured parameter list. No redundant sentences, making it efficient for an AI agent to parse.

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?

Despite having an output schema, the description lacks essential context such as whether changes are permanent or temporary, whether the asset must be open, and error handling for invalid inputs. This gap reduces completeness for a setter tool.

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?

Input schema has 0% coverage, but the description includes an 'Args' section with brief explanations, examples (e.g., '5.0 for 5 second preview'), and defaults. This adds significant value beyond the schema, though 'system_path' could be more precise about the asset path format.

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 clearly states the tool's function: 'Set the timeline playback range in the Niagara editor.' It distinguishes from the sibling tool 'get_niagara_playback_range' and provides practical examples of when to adjust the range (e.g., short-lived effects, looping effects).

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 gives concrete usage advice: extend range for effects dying quickly, use longer range for looping effects. However, it lacks explicit exclusions or comparisons to alternative tools beyond the implicit getter/setter distinction.

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