Validate Cmx3600 Edl

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

Annotations declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false. The description adds the validation scope and the local-file constraint, but does not explain the non-read-only or non-idempotent behavior, which is unexpected for a 'validate' operation. With annotations present, this leaves a moderate gap.

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?

Consists of a single well-structured sentence, front-loaded with the action and object. Every clause enumerates a distinct validation check and earns its place; no filler.

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 that an output schema exists and annotations supply safety hints, the description provides the validation scope and usage context. It omits any explanation of the non-read-only annotation, but is otherwise complete enough for a validation utility.

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 coverage is 100%, so the schema already documents both parameters (path, frame_rate) with descriptions. The description adds no parameter-specific syntax or constraints beyond what the schema provides, so the baseline of 3 applies.

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?

States a specific verb 'Validate' and resource 'CMX 3600 EDL', and enumerates the aspects validated (grammar, timecodes, durations, duplicate event IDs, record overlaps, record gaps). However, it does not explicitly differentiate from sibling tools like inspect_cmx3600_edl or compare_cmx3600_edls, so it falls short of a 5.

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?

Provides clear context: 'before user-assisted Premiere interchange,' indicating the appropriate use case. But it does not state when not to use it or name alternative tools, so exclusions are missing.

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