Reddit thread video

create_reddit_thread

Create a Reddit thread animation. All options controllable (nested comments supported). Free-plan exports include a MockClip watermark and the free plan includes 2 MCP renders; if the caller is on the free plan, mention that they can upgrade at /pricing for watermark-free exports and more renders.

Input Schema

NameRequiredDescriptionDefault
postYes
themeNo
sceneIdNoComposite the clip onto real footage of a hand holding a phone, for a filmed look. Overrides videoFormat and showBezel: the export takes the scene's aspect, with the footage around the phone. Vertical 9:16 scenes: "outdoors" (outdoors), "bookshelf" (bookshelf), "two-hands" (two hands), "on-desk" (on the desk), "dim-room" (dim room). Landscape 16:9 scenes (YouTube, presentations): "city-wide" (city), "desk-wide" (desk), "neon-wide" (neon), "studio-wide" (studio). Default: none.
commentsYes
showBezelNoDraw the iPhone bezel around the screen (default true). With 1:1 it frames the top of the phone; false gives a plain frame.
textScaleNoText size: a zoom of the phone UI (text, bubbles, avatars, bars, keyboard, notification banners) as a multiplier from 1 (default, the app's real size) to 1.5, in steps of 0.1 — use it when a short conversation or a single notification should fill the screen. Chat and notification apps only; the other apps ignore it.
videoFormatNoOutput aspect ratio. "1:1" is a square for feed posts: chat apps fit the conversation into the square, the other apps show the top of the screen (phone-call ignores it). "9:16", "9:19.5" (iPhone) and "3:2" apply with showBezel false. Default: the iPhone bezel, 9:16.
exportFormatNoOutput file. "mp4" (default) and "gif" are opaque. "webm" (VP9) and "mov" (ProRes 4444, large files) keep an alpha channel: the only way a transparent background, or the corners around the phone bezel, stay transparent. With background.backgroundType "transparent" and no exportFormat the clip exports as webm. Transparent WebM / MOV export needs a Creator or Studio plan; on other plans the clip is made as mp4 and the reply says so.
exportQualityNoResolution and frame rate of the file: "720p" or "1080p" (Full HD) at 15, 24, 30 or 60 fps, e.g. "1080p-30". Default "720p-30". Full HD takes up to 4× as long to export; 60 fps about twice as long and needs a Creator or Studio plan — on other plans the clip is made at 30 fps and the reply says so.
showStatusBarNoDraw the iOS status bar (time, signal, battery) at the top of the screen (default true). Applies with showBezel false or a sceneId: inside the iPhone bezel the status bar is always drawn, so to remove it set showBezel false too.
soundSettingsNo
showHomeIndicatorNoDraw the iOS home indicator bar at the bottom of the screen (default true).

  4. First observed

TDQS

B3.4/5.0
Behavior4/5

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

With annotations covering the safety profile (not read-only, non-destructive, non-idempotent, closed-world), the description adds genuine behavioral context: free-plan exports carry a MockClip watermark, the free plan caps at 2 MCP renders, and the caller should surface the /pricing upgrade path. These are real operational traits beyond the structured fields, though export timing/async behavior remains unexplained.

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?

The purpose is front-loaded in the first sentence and the sentences are compact. The final pricing sentence is long but functions as an actionable instruction to the agent rather than padding, so waste is limited.

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

Completeness3/5

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

For a 12-parameter tool with nested objects and no output schema, the description covers cost/watermark constraints but omits what the tool returns (export URL? job handle?), whether rendering is synchronous or long-running, and any per-call limits beyond the free-tier render count. Adequate but with clear gaps for a tool this complex.

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 67%, with the enumerated parameters (sceneId, videoFormat, exportFormat, exportQuality, textScale) already well documented in the schema. The description only adds 'nested comments supported', which marginally clarifies the comments array's recursive nature that the schema exposes via a self-referencing $ref.

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

Purpose4/5

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

The description states a specific verb+resource ('Create a Reddit thread animation'), which cleanly distinguishes it from the many sibling conversation/feed tools. However, 'All options controllable' is vague filler that adds no discriminating information beyond the title.

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 guidance on when to use this tool versus alternatives, no prerequisites, and no conditions beyond the free-plan pricing nudge. The intended use (render a Reddit thread as video) is only implied by the tool name and title.

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