transition_morph

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states 'apply morph transition' but does not explain if files are modified, what output is produced, or any side effects. The agent lacks critical information about the tool's behavior beyond its basic purpose.

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 concise sentence, which is structurally efficient. However, it lacks necessary details, making it under-specified rather than optimally concise. It earns a middle score for brevity without completeness.

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 has 5 parameters, 0% schema description, and no annotations, the description is insufficient. It does not mention the output schema or explain parameters like duration and mesh_size. The agent would struggle to invoke the tool correctly without additional information.

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 explain all parameters. However, it only vaguely references 'two video clips' for clip1_path and clip2_path, and completely ignores output_path, duration, and mesh_size. The agent cannot infer the meaning or format of these parameters.

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 explicitly states 'Apply morph transition between two video clips,' which clearly identifies the tool's action (apply morph transition) and resource (two video clips). This distinguishes it from sibling transitions like 'transition_glitch' or 'transition_pixelate' by naming the specific morph effect.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, limitations, or scenarios where other transitions are preferable. The agent has no context to decide between morph, glitch, or pixelate transitions.

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