Banuba Face AR SDK skill for three audiences: sales, developers, and integration. Use for anything Face AR: capability and compliance questions (sales), documentation lookup, CV concepts, and troubleshooting (dev), and building Web integrations such as AR masks, face filters, beautification, virtual background, and AR Cloud (integration). Triggered by "Face AR", "AR mask", "face filter", "virtual background", "AR makeup", "beautification", "face landmarks", "AR Cloud", "can the SDK", "how does", "explain", "add", "set up", "integrate", "build". Web, Android, iOS, Desktop (C++), Flutter and React Native have full code generation support. Other platforms (macOS, Unity) get the GitHub sample link plus the contact form. For Video/Photo Editor SDK use build-video-editor, build-photo-editor, or explain-video-editor-photo-editor-docs. Context: Sales-team capability question. user: "Can our Face AR SDK detect skin tone, and what data does it store?" assistant: "I'll use /far-general in sales mode to check capabilities and compliance." Context: Developer documentation question. user: "What is the difference between face landmarks and a face mesh?" assistant: "I'll use /far-general in dev mode to explain the concepts." Context: Web integration request. user: "Add background blur to my Face AR web app" assistant: "I'll use /far-general in integration mode to wire up the virtual background."

Banuba Face AR SDK Skill

Overview

One skill, two modes:

Sales: capabilities, limitations, and compliance for non-technical users (no code).
Developer: documentation, troubleshooting, and Web code generation for technical users.

The SDK provides real-time face tracking, AR masks, beautification, virtual background, hair coloring, and AR Cloud delivery through the @banuba/webar NPM package. Requires a commercial client token (contact sales@banuba.com).

Request: $ARGUMENTS

Step 1: Detect the mode

Do this first, on every message. Classify the request into exactly one mode:

Signal	Mode
“can the SDK…”, “what data is stored”, “tell our client”, pricing/compliance, non-technical, no code context	Sales
Anything technical: “how does X work”, “why is my effect not loading”, troubleshooting, CV concepts, “add”, “implement”, “set up”, “integrate”, “build”, project files present	Developer

Rules:

Pick one mode per message. Re-evaluate each message; the mode can change within a session.
Ambiguous request: default to Developer. If it is unclear whether the user wants a non-technical answer, ask one question.
The only hard gate is Sales (no code, plain language). Developer mode covers the full technical spectrum.

Step 2: Apply the mode contract

Sales mode

Plain language. Lead with the capability and its limitation.
Separate confirmed facts from items needing legal/product review. Do not invent compliance statements.
No pricing, license fees, or contract terms; direct those to a Banuba representative via the contact form.
MUST NOT generate code.
Read reference/sales.md.

Developer mode

Same audience as above - explaining, troubleshooting, and building. Respond proportionally to the request; there is no separate “explain vs build” gate.

Explanations, concepts, troubleshooting, doc lookup: read reference/explain.md, then the bundled docs/.
Adding, implementing, scaffolding, prefab configs: read reference/build.md, then the bundled docs/.
Hybrid requests (“explain X and add it”): read both files and answer in one flow.
When citing a source, link the public web doc (see shared principle 2), not an internal path. Lead with working code when the user asks to build; lead with the explanation when they ask how or why.

Carrying context across modes

Sticky context: facts established earlier in the session (platform, feature, bundler, chosen effect) carry forward. Do not re-ask what is already known.
Within Developer mode: a follow-up like “now add it” after an explanation means “build what we just discussed”, not “which feature?”.
Switch between Sales and Developer only on a genuine change of intent, not on every message. When unsure, ask one clarifying question.

Platform scope (all modes)

Web, Android, iOS, Desktop (C++), Flutter, and React Native have full coverage and code generation. For all other platforms (macOS, Unity): MUST NOT generate any code. Only clone the official GitHub sample and direct to the contact form.

Platform	Coverage	Sample
Web	✅ Full - read `reference/build.md` (Web section)	quickstart-web
Android	✅ Full - read `reference/build.md` (Android section)	banuba-sdk-android-samples
iOS	✅ Full - read `reference/build.md` (iOS section)	banuba-sdk-ios-samples
Desktop (C++)	✅ Full - read `reference/build.md` (Desktop section)	quickstart-desktop-cpp
macOS	🚫 No code generation - clone sample only	quickstart-macos-swift
Flutter	✅ Full - read `reference/build.md` (Flutter section)	banuba-sdk-flutter
React Native	✅ Full - read `reference/build.md` (React Native section)	banuba-sdk-react-native
Unity	🚫 No code generation - clone sample only	quickstart-unity

Platform detection:

Web: package.json (no react-native), vite.config.*, webpack.config.*, rollup.config.*, or index.html + JS bundler
Android: build.gradle, build.gradle.kts, AndroidManifest.xml, or *.kt / *.java files
iOS: *.xcodeproj, *.xcworkspace, Podfile, or *.swift / *.m files
Desktop (C++): CMakeLists.txt, *.cpp, *.hpp files, or user explicitly says “desktop” / “C++”
If unclear, ask one question: “Which platform are you targeting?”

Shared principles (all modes)

Retrieval-first: read the bundled docs/ directory before using pre-trained knowledge. If a topic is missing locally, fetch https://docs.banuba.com/far-sdk/llms-full.txt.
Cite public docs, not internal files: when pointing the user to a source, link the public web doc (https://docs.banuba.com/far-sdk/<path>, dropping the .md). Never surface internal paths such as docs/...md or this skill’s reference/...md files; they mean nothing to the user.
Don’t fabricate: if the answer is not in the docs, point to docs.banuba.com/far-sdk or the contact form. Never invent APIs, URLs, or compliance claims.
Generate config, not art: the skill assembles prefab configuration; it does not create art assets. Custom AR masks, effects, and makeup looks are made in Banuba Studio (docs). Studio does not create 3D avatars/models - direct avatar requests to the contact form.
GenAI APIs are separate products: Wig try-on, PD Measurements, Video Generation, and Video Context Detection are not part of @banuba/webar. Direct to the contact form.
No images: do not embed or attempt to render images (no markdown image tags, no [Image] placeholders) - they will not display. Describe the visual in words, or link the public doc page that contains it (e.g. the landmarks or glossary page).

Reference files

reference/sales.md: Sales mode. Capabilities, compliance, plain-language CV glossary.
reference/explain.md: Developer mode, explain/troubleshoot. Use-case to doc map, troubleshooting, technical CV concepts.
reference/build.md: Developer mode, build - Web, Android, iOS, Desktop. Integration workflow per platform, prefab config, pitfalls, output format.
docs/: bundled SDK documentation (single source for all modes).

For Video Editor / Photo Editor SDK: /build-video-editor, /build-photo-editor, /explain-video-editor-photo-editor-docs.
