Get Caption Style Guidance

get_caption_style_guidance

Read-onlyIdempotent

Convert caption style presets or custom looks and keyword highlights into step-by-step Premiere 2024+ Track Style, upgrade, and render-verification instructions without altering captions.

Instructions

Read-only caption style guidance: a preset and/or custom_style turned into Premiere 2024+ Properties-panel Track Style steps, plus keyword_highlight per-word steps, manual Upgrade Caption to Graphic steps, and render-verification routes. NEVER modifies captions: Premiere has no caption style, per-word, or upgrade API.

Input Schema

Name	Required	Description
`preset`	No	Style preset to describe (default clean when custom_style is omitted).
`custom_style`	No	Optional caption look to translate into concrete Premiere UI steps. Every field is optional; at least one is required. Values are documentation only and are never applied.
`keyword_highlight`	No	Optional words to colour inside captions. Returns manual Program Monitor steps; nothing is applied, because Premiere has no per-word caption styling API.
`expected_cep_target`	No	Optional reviewed CEP sequence/clip identity and exact tick ranges. Checked before every generated command; UXP refuses this CEP-only guard.
`expected_project_path`	No	Optional 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

Name	Required	Description
`ok`	Yes	Whether the tool completed successfully.
`data`	No	Tool-specific result data when ok is true; on failure, diagnostic detail when the tool provides it.
`tool`	Yes	The registered MCP tool name.
`error`	No	Failure detail when ok is false.
`receipt`	No	Versioned common mutation receipt; success never implies rendered verification.
`idempotency`	No	Present when idempotency_key deduplicated this call: replayed is true when the original outcome was returned instead of running again.

TDQS

A4.6/5.0

Behavior5/5

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, but the description adds the non-obvious reason: 'NEVER modifies captions: Premiere has no caption style, per-word, or upgrade API.' It also clarifies that the custom_style values are documentation only and never applied, which is exactly the behavioral fact an agent would otherwise get wrong.

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

Conciseness5/5

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

Two sentences, both front-loaded with the highest-value fact first (read-only guidance, what steps it emits) and the critical constraint second. No filler, no restating of the title.

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

Completeness4/5

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

With rich annotations, full schema coverage and a declared output schema, the description covers what matters: what it emits and why nothing is mutated. It leaves unstated any version caveats beyond 'Premiere 2024+' and any limits on how many steps/routes are returned, but nothing essential to calling it correctly is missing.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3; the description earns more by explaining how the top-level parameters combine — 'a preset and/or custom_style' as one guidance mode, keyword_highlight as a second, and the remaining rendered verification routes. It does not explain expected_cep_target / expected_project_path, which the schema carries.

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

Purpose5/5

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

States a specific verb and resource ('Read-only caption style guidance'), and enumerates exactly what it produces: Premiere 2024+ Properties-panel Track Style steps, per-word keyword_highlight steps, Upgrade Caption to Graphic steps, and render-verification routes. That output inventory distinguishes it cleanly from siblings like build_caption_artifact, create_caption_track, or check_caption_safe_zone.

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

Usage Guidelines4/5

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

The description makes the usage context clear: this is the tool to call when you need manual UI steps rather than an applied edit, and the 'render-verification routes' output hints at the verification follow-ons. It never names a concrete alternative tool (e.g. build_caption_artifact for producing caption files), so routing is implied rather than explicit.

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