TDQS

C2.5/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false, and openWorldHint=false, covering the safety profile. The description adds no behavioral context beyond that — it does not say what the new sequence is named, whether the duplicate becomes active, whether it copies markers/tracks, or where it lands in the project.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single front-loaded phrase with no waste, but it is under-specified rather than genuinely concise — the brevity comes at the cost of all useful context for a mutating tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained. Still, for a tool that creates a new sequence, the description never addresses the naming of the duplicate, its placement, or its active state — meaningful gaps for a one-parameter mutation whose sibling set is crowded.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and the single sequence_id parameter is fully documented in the schema ('Sequence name or ID to duplicate'). The description contributes nothing beyond that, which is the expected baseline when the schema does all the work.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Duplicate an existing sequence'), so the basic action is discernible. However, it is essentially a restatement of the title with zero differentiation from siblings such as duplicate_clip, create_subsequence, unnest_sequence, or create_sequence_from_clips — an agent gets no help distinguishing which duplication tool to pick.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no prerequisite (e.g., sequence must exist, project must be open), and no mention of alternative tools like create_sequence_from_preset that might achieve a similar outcome. The agent must infer usage entirely.

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