Set Anti Alias Quality

set_anti_alias_quality

Enable or disable anti-aliasing on a clip's Motion effect to improve edge quality on scaled or rotated footage.

Instructions

Set the anti-alias quality on a clip's Motion effect (useful for scaled/rotated clips).

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Input Schema

NameRequiredDescriptionDefault
enabledYesEnable (true) or disable (false) anti-aliasing
node_idYesNode ID of the clip
idempotency_keyNoOptional client-chosen key (1-128 chars of A-Z a-z 0-9 . _ : -) for this intended edit. Pass a fresh key per edit and reuse it only when retrying that same edit, for example after a client-side timeout. A repeat with the same tool, key and arguments is not run again: while the first call is running it fails with IDEMPOTENCY_IN_PROGRESS (poll get_last_operations); after it finished it returns the original outcome marked replayed. A definite failure with nothing applied (receipt outcome not_applied) may be retried with the same key. Reusing a key with different arguments fails with IDEMPOTENCY_KEY_REUSED. Scoped to this MCP session (the stdio server process, or the HTTP server process when Streamable HTTP is stateless per request) and held in memory only (200 keys, 1 hour); it does not survive a restart or reconnect. Read-only invocations are never deduplicated.
expected_cep_targetNoOptional reviewed CEP sequence/clip identity and exact tick ranges. Checked before every generated command; UXP refuses this CEP-only guard.
expected_project_pathNoOptional absolute saved-project path. Every generated CEP command refuses before its body when the active project differs or is unsaved. UXP commands refuse this CEP-only guard; local-only tools do not inspect Premiere. Omit to keep existing behavior.

Output Schema

NameRequiredDescriptionDefault
okYesWhether the tool completed successfully.
dataNoTool-specific result data when ok is true; on failure, diagnostic detail when the tool provides it.
toolYesThe registered MCP tool name.
errorNoFailure detail when ok is false.
receiptNoVersioned common mutation receipt; success never implies rendered verification.
idempotencyNoPresent when idempotency_key deduplicated this call: replayed is true when the original outcome was returned instead of running again.

C2.8/5.0
Behavior2/5

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

Annotations already declare readOnlyHint=false, destructiveHint=false, openWorldHint=false and idempotentHint=false, so the safety profile is partially covered. Beyond that, the description discloses nothing: not whether a Motion effect must already exist, what happens if it does not, whether other Motion settings are touched, or how the idempotency key and CEP guard parameters behave in practice. For a mutation tool the added context is minimal.

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

Conciseness4/5

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

A single front-loaded sentence with no filler or repetition. It is efficient, though the brevity comes at the cost of substance rather than being a model of tightness.

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?

The tool takes five parameters including nested reviewed-identity guards, carries an idempotency contract, and returns a defined output schema. Against that complexity, one sentence leaves key operational questions unanswered, notably prerequisites (an existing Motion effect) and what the guard parameters protect against. The output schema covers return values, but the preconditions do not.

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 every parameter, including the nested `expected_cep_target` and `expected_project_path` guards and the `idempotency_key` contract, is documented in the schema itself. The description only restates that `node_id` refers to a clip and that `enabled` toggles anti-aliasing, adding no semantics beyond the schema. The baseline of 3 applies when the schema does the heavy lifting.

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?

The verb and resource are named concretely ("Set the anti-alias quality on a clip's Motion effect"), so the target is identifiable. However, "quality" implies a graded level while the required `enabled` parameter is a plain boolean toggle, and the description never resolves that mismatch. It also does not distinguish this from adjacent transform tools such as set_clip_scale or set_clip_rotation, which are the operations that make anti-aliasing relevant.

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

Usage Guidelines3/5

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

The parenthetical "(useful for scaled/rotated clips)" is a genuine when-to-use hint, which is more than nothing. But there is no guidance on when to disable it, no mention of a prerequisite Motion effect, and no reference to any alternative tool for the same visual outcome. Usage is implied rather than stated.

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