Compare Cmx3600 Edls

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

The description explicitly claims 'Read-only; it does not alter either interchange file or Premiere,' but the annotations set readOnlyHint to false. This is a direct contradiction between the description and structured metadata, which undermines an agent's trust in side-effect expectations.

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 entire description is one focused sentence with no filler. It front-loads the action and resource, then adds the key behavioral caveat and the nature of the report.

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?

With an output schema present and full parameter schema coverage, the description gives enough context: inputs are local EDLs, comparison key is event number, and the outcome is a bounded list of added/removed/changed events. The term 'bounded' is slightly under-specified but not fatal.

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 100%, so the baseline is 3. The parameter descriptions ('Existing revised .edl file' and 'Existing baseline .edl file') already clarify role and expected state; the main description does not add further parameter-level meaning.

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 names a specific verb ('Compare'), a specific resource ('two local CMX 3600 EDLs'), and the comparison dimension ('by event number'), and lists the output classes: added, removed, and changed editorial events. This clearly distinguishes the tool from siblings like inspect_cmx3600_edl and validate_cmx3600_edl.

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 context is clear: use this for comparing two local CMX 3600 EDL files, not for inspecting or validating a single EDL. However, it does not explicitly name alternatives or state when not to use the tool, so it stops short of full routing guidance.

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