glitch_vhs_tracking

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

No annotations are provided, so the description carries the full burden. It specifies that the tool simulates analog noise, color bleed, and rolling bands, and outputs a dictionary with success status and output path. It does not mention potential errors or side effects, but for a simple effect tool, this is minimally adequate.

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 short opening line explaining the effect, followed by a clear list of parameters. It is well-structured and front-loaded, though the parameter list could be slightly more compact.

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?

Given the tool's medium complexity (6 parameters, no nested objects, output schema exists), the description covers the purpose, parameters, and return value adequately. It does not delve into edge cases or error handling, but is sufficient for correct invocation.

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?

The input schema has 0% description coverage, so the description compensates fully. Each parameter is explained with context (e.g., 'Tracking error intensity (0-1)', 'Red channel shift in pixels'), adding meaning beyond the schema's types and defaults. The return value is also described.

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 applies a VHS tracking error glitch effect, with a specific verb ('apply') and resource ('VHS tracking error glitch effect'). It distinguishes from sibling glitch tools by specifying the VHS analog noise style.

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 implies the tool is for VHS-style glitch effects but does not explicitly state when to use it versus other glitch tools or provide exclusions. The agent must infer from the effect description alone.

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