langchain-ai/design-agent.

brand-design

Visual judgment for a new asset or a restyle of a supplied one. The concept gate, choosing ground, accent and type from the brand pack, and preserving a supplied reference.

brand-onboarding

Build the active brand pack in workspace/brand/ from a brand guide, website, files or a Paper file, validate it, and have a person review it.

content-brief

Turn a vague or multi-asset design ask into a brief. Pull what is already known, ask at most two questions with reasons, decide the rest and say what you decided.

data-viz

Charts, stat cards, flywheels and diagrams (flows, architectures, hierarchies) rendered on brand from a JSON spec to PNG and SVG. Use for any visual whose job is numbers or relationships, including restyling an attached chart or diagram.

design-agent-customize

Change what Design Agent knows and does. Teach it a new deliverable with a runtime skill, change its instructions, design doctrine or checks, connect MCP servers and tools, or change models and cost caps. Use when someone wants it to make something new, follow a new rule, or use another tool.

design-agent-deploy

Put Design Agent in a team's Slack. Deploy it to Managed Deep Agents (one command, managed Slack app) or self-host it with Docker Compose, verify it with a real request, ship updates, and keep a separate test copy. Use when someone wants the agent running for their team.

design-agent-evals

Find out whether a change made Design Agent better or worse. Run the eval set or a few tasks before and after against the same model, read the reports, look at the files, and turn a real request that went wrong into a task. Use after changing instructions, skills, checks or models, or when someone asks how good it is.

design-agent-onboarding

Install and configure Design Agent, add a brand, connect Paper, choose MDA or self-hosting, and diagnose setup without exposing credentials.

design-agent-troubleshoot

Diagnose Design Agent when something fails. Setup, a render, a deploy, Slack or a model call. Run doctor and the connection tests, read logs and traces, match the symptom to its fix, and never print credentials. Use when a command errors, a reply never comes, or a file looks wrong.

design-agent-update

Bring a fork or clone of Design Agent up to date with the upstream repository while keeping the team's brand, skills and edits, rebuild what changed, and redeploy safely. Use when someone asks to update, upgrade or pull the latest Design Agent.

design-wiki

Design doctrine to weigh on any visual. Hierarchy, typography, colour, layout, platform sizes, chart and diagram principles, and the review rubric critics score against.

embedded-captions

faceless-explainer

Turn arbitrary text — an article, notes, a topic, a brief — into a faceless explainer video: there is no site or footage to capture, so the visuals are invented per scene (typography, abstract graphics, diagrams, data-viz). Use for topic explainers, concept breakdowns, how-tos, listicles. Not a video built from a website (/product-launch-video — promo or tour). Unclear → /hyperframes.

film-breakdown

Measure a film someone hands you (cuts, contact sheets, motion energy, beat grid, colours) and compare a recreation against it frame by frame. Use for "recreate this", "make one like this", "what makes this work", "match this pacing" or "time it to this track".

general-video

>

gif-edit

Edit animated GIFs and screen-recording GIFs with ffmpeg and sharp (reframe to exact dimensions, swap on-frame text, retime, trim or reorder the loop, add a zoom-and-pan camera, encode small). Still images go to image-ops.

hyperframes-animation

All animation knowledge for HyperFrames — atomic motion rules, multi-phase scene blueprints, scene transitions, broader motion-design techniques, AND the seven runtime adapters (GSAP default, plus Lottie, Three.js, Anime.js, CSS keyframes, Web Animations API, TypeGPU). Use for any motion or animation task: pick 2-4 rules and compose, or load a blueprint, or look up runtime-specific API (e.g. GSAP eases / Lottie player / Three.js mixer). Also covers auditing an existing composition's choreography (animation map) and 24 named text-animation effects. HyperFrames-native: single paused timeline, seek-safe, deterministic.

hyperframes-audio

>

hyperframes-core

The HyperFrames composition contract — build one renderable project. Use for composition structure, the `data-*` timing attributes, `class="clip"`, tracks, sub-compositions, variables, framework-owned media playback, deterministic-render rules, and validation. Read before writing composition HTML.

hyperframes-creative

Non-animation creative direction for HyperFrames videos. Use for design spec (frame.md / design.md) handling, palettes, typography, narration, beat planning, audio-reactive visuals, composition patterns, and brand / style decisions. For atomic motion patterns and scene blueprints, use `hyperframes-animation`.

hyperframes-keyframes

>

image-ops

Deterministic pixel work on an existing image with sharp, Photoshop's image menu in code (resize, crop, rotate, tint, trim, flatten, pad, composite with blend modes, convert, compress, read metadata). Not for new pictures or branded layouts.

langsmith-dataset

INVOKE THIS SKILL when creating evaluation datasets, uploading datasets to LangSmith, or managing existing datasets. Covers dataset types (final_response, single_step, trajectory, RAG), CLI management commands, SDK-based creation, and example management. Uses the langsmith CLI tool.

langsmith-evaluator

INVOKE THIS SKILL when building evaluation pipelines for LangSmith. Covers three core components: (1) Creating Evaluators - LLM-as-Judge, custom code; (2) Defining Run Functions - how to capture outputs and trajectories from your agent; (3) Running Evaluations - locally with evaluate() or auto-run via LangSmith. Uses the langsmith CLI tool.

launch-film

Direct and produce a 30 s to 3 min launch film, teaser or recreation with helpers, from brief and storyboard approval through parallel acts, reviews, the final render and cut-downs.

media-production

Route any design or motion request to the right pipeline and skill, from a single still to a launch film. Use first for every new ask.

media-use

Agent Media OS for a HyperFrames project. Resolve BGM, SFX, image, icon, brand logo, voice, color grade, or LUT into a frozen local file or paste-ready block + ledger record (one verb, `resolve`); generate via TTS / music / image models when the catalog misses; produce voiceover, transcription, captions, and background removal through one shared audio engine; operate on media (cut / reframe / transform); and reuse assets across projects. Also use for vague feedback that real footage looks dark, flat, boring, should feel retro/camcorder/print/ASCII, needs privacy, or needs a media reveal. When the host app provides its own music or sound-effect tools, use those for music and sound effects; `resolve --type bgm|sfx` needs the heygen CLI. When `HEYGEN_API_BASE` is set, HeyGen calls go through that host with no CLI sign-in.

motion-direction

Direct and review motion built in HyperFrames, from a sting to a film. The idea and its turn, timing on a grid, craft, named moves, sound on the picture, and the review rubric.

motion-graphics

>

music-to-video

Turn a music track (an audio file, a video to pull audio from, or a track generated from a mood brief) into a beat-synced video — lyric video, slideshow, or kinetic promo. The music drives all pacing; any user-supplied images/videos are cut onto the same beat grid, and a complete video needs zero assets. Narrated pieces → the input-matched workflow (see /hyperframes). Unclear → /hyperframes.

paper-design

Draft on the shared Paper canvas when paper_ tools are present (layouts, storyboard twins, thumbnails people will nudge), read a Paper brand file, and what to do when Paper is not connected.

pr-to-video

Turn a GitHub pull request (a PR URL, owner/repo#N, or 'this PR' in a checked-out repo) into a code-change explainer video — changelog, feature reveal, fix, or refactor walkthrough built from the diff, commits, and files: the input is a code change, not a website. Not a product promo (/product-launch-video) or a no-PR topic explainer (/faceless-explainer). Unclear → /hyperframes.

reference-study

Study a film someone supplies, frame by frame, to learn what makes it work. Measure it, write a teardown, and propose observations or skill edits for a person to approve.

release-check

Run the release gates before tagging a Design Agent release: hygiene, secrets, licenses, docs, tests, and the human reviews.

slideshow

>

sound

Sound for a film or animation, covering voiceover, music bed, sound effects, UI cues, mixing and mastering to -14 LUFS. Use when a video needs sound, a voiceover, or a silent render needs a score.

stills

On-brand still images built as HTML and rendered in a real browser, such as ads and banners in several sizes, social images, carousels, and paged PDFs (one-pagers, booklets, static decks). Not for charts or diagrams (data-viz), thumbnails or motion.

thumbnails

Video thumbnails and A/B thumbnail sets, including refreshes of an older video's thumbnail, with small-size legibility checks. A thumbnail is a still; banners and social images go to stills.

vendor-sync

Move a vendored upstream (HyperFrames, LangSmith skills, Deep Agents skills) to a newer pin, re-vendor its skills unmodified, verify them, and update everything that depends on the pin.

visual-verify

Look at your own renders before delivery and fix what is off. A restyle beside its source, a pixel-level fix as zoomed before/after crops, a video as a filmstrip of key frames.
