validate_export_preset

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

Annotations show non-readonly and non-destructive, but the description adds behavioral context: it interacts with the active sequence. However, it does not disclose whether any state changes occur (e.g., locking the sequence) or what happens if the preset is missing, nor does it mention permissions or rate limits.

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 two sentences, directly stating the two actions. It is compact and front-loaded, but could be slightly improved by using a more structured format (e.g., bullet list) or clearer separation of concerns.

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 low complexity (one parameter, no output schema), the description covers the basic purpose but does not specify return values (e.g., boolean or extension string) or error conditions (e.g., what if preset does not exist or no active sequence). This leaves gaps for an AI agent.

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?

With 100% schema coverage, the parameter description already defines the parameter as a full path to an .epr file. The description only restates what the schema provides, adding no new meaning. Baseline 3 is appropriate.

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 validates the existence of an Adobe Media Encoder .epr preset and queries the active Premiere sequence for its output extension. It distinguishes itself from siblings like verify_delivery_file and get_export_file_extension by the specific two-step action.

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 does not specify when to use this tool versus alternatives such as verify_delivery_file, get_export_file_extension, or get_encoder_presets. It also lacks prerequisites (e.g., requirement of an active sequence) and does not mention when not to use it.

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