Set Sequence Settings

set_sequence_settings

Set a sequence's frame width and height in pixels, then retrieve the updated settings. Specify a sequence ID or use the active sequence.

Instructions

Modify and read back sequence frame-size settings.

Input Schema

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
okYesWhether the tool completed successfully.
dataNoTool-specific result data when ok is true; on failure, diagnostic detail when the tool provides it.

TDQS

C2.5/5.0
Behavior2/5

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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=false), so the description's only added behavioral note is the 'read back' phrase, which is redundant given an output schema exists. It says nothing about permissions/undo, partial updates (width-only or height-only), or effects on existing clip framing.

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 sentence with no filler, which is structurally fine, but it is so thin (and the 'read back' clause so ambiguous) that it borders on under-specification rather than crisp conciseness.

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?

For a mutation tool with several overlapping siblings, the description omits the two things an agent most needs: how it differs from set_sequence_resolution and whether omitting width or height is allowed. The output schema covers return values, but the routing and partial-update gaps remain.

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 schema already documents width, height, and sequence_id semantics (including the active-sequence default). The description's 'frame-size' phrasing loosely maps to width/height but adds no format or constraint detail beyond the schema, so the baseline of 3 applies.

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 ('Modify') and resource ('sequence frame-size settings'), plus a read-back behavior. However, 'frame-size' is not clearly distinguished from the sibling 'set_sequence_resolution', and several other siblings (set_sequence_pixel_aspect_ratio, set_sequence_field_type, set_sequence_display_format) touch the same settings surface, so an agent cannot reliably tell which tool owns width/height from this text alone.

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?

No when-to-use guidance and no named alternatives, despite a large sibling set containing a near-duplicate (set_sequence_resolution) and a read counterpart (get_sequence_settings). The agent must infer routing entirely on its own.

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