Cangjie Skill distills books, long videos, and podcasts into callable AI Agent Skills using the RIA-TV++ methodology.
Key features
- RIA-TV++ Distillation Method: A structured methodology that pulls extractable, verifiable, transferable methodologies out of long-form source material.
- Multi-Format Ingestion: Works with books, long videos with subtitles or transcripts, podcasts, interviews, speeches, courses, and long articles.
- Skill Composability: Distilled outputs are independent Agent Skills that can be called individually or composed with other skills.
- Stress-Test Validation: Every skill is stress-tested so distilled methodology actually holds up in real problem-solving, not just summary form.
- Platform Compatibility: Runs on Claude Code and OpenClaw, so distilled skills plug directly into existing agent workflows.
- Video Pipeline Integration: Pairs with a companion video-downloader skill to fetch subtitles, audio transcripts, and key assets before distillation.
Best for
- Book to Actionable Skill: Turn a business or self-help book into a callable skill that helps you apply its framework during real decisions.
- Long Video Knowledge Capture: Distill a two-hour interview or Bilibili/YouTube deep dive into a reusable methodology skill.
- Podcast Methodology Extraction: Convert recurring podcast frameworks into a library of composable agent skills.
- Course Companion: Package a paid course's methodology into a skill an agent can invoke while the student is doing real work.
- Personal Knowledge Base for Agents: Build a growing library of methodology skills that your coding agent can call on demand.
- Team Playbook Distillation: Convert long internal training material into structured, callable skills for teammates.
Google Opal
A Google platform for building, running, and sharing small AI-powered mini-apps and content transformation workflows.
Key features
- Mini‑App Templates: Provides ready-made mini-app starter projects (example: Article → LinkedIn post) with copy‑paste prompts and wiring to accelerate development of small, focused AI apps.
- Prompt & Wiring Instructions: Includes instruction files (miniapp_instructions.md) with example prompts, step wiring, and sharing notes so developers can reproduce and customize behaviors.
- Workflow Integrations: Documented fallbacks and example integrations with workflow tools such as n8n and Python scripts to run pipelines when Opal access is unavailable or to connect generated content to downstream systems.
- Developer‑First Repos: Official and community GitHub starter repositories that include demo code, n8n workflows, and quick‑start commands to bootstrap mini‑apps and share them publicly.
- Regional Beta Access Controls: Distributed as a gated public beta (noted as US‑only in the referenced materials), indicating controlled rollout and access management during early release.
- Content Transformation Primitives: Focused capabilities for converting input content into formatted outputs (summaries, social posts, etc.) with constraints such as length and tone encoded in templates.
- Web-hosted mini-app platform accessible via opal.withgoogle.com (public beta)
- Support for developer mini-apps with copy-paste prompts, step wiring, and sharing notes (mini-app starter repo)
- Example content transformation pipeline (article or raw text → LinkedIn-style post)
- Fallback integration examples using Python scripts and n8n workflows
- Docker Compose usage shown in community repos for local fallback runs
- Developer-focused starter templates and instructions in repositories (e.g., opal/miniapp_instructions.md)
Best for
- Article Repurposing: Convert a long-form article or blog post into a concise, engaging LinkedIn post with a punchy hook, bullets, and a CTA using a mini‑app template.
- Marketing Automation: Prototype and automate content pipelines that ingest source material, generate repurposed social content, and push outputs to content management or scheduling tools via n8n.
- Developer Prototyping: Rapidly build and iterate small AI apps for internal tools or customer demos using the provided starter repos and prompt wiring instructions.
- Fallback Workflows: Run equivalent generation flows locally via Python or in workflow orchestrators when Opal access is restricted (e.g., during regional beta limitations).
- Shared Mini‑App Catalog: Publish and share mini‑apps on GitHub to enable team collaboration and reuse of proven prompt templates and wiring patterns.
- Content Team Productivity: Enable non‑technical content creators to use developer‑provided mini‑apps for consistent, repeatable social and marketing content generation.
- Create micro-apps that transform articles or raw text into social posts or summaries
- Prototype prompt-driven workflows and share mini-apps with collaborators
- Run automation/ETL fallbacks using Python or n8n when direct Opal access is unavailable
- Embed or orchestrate content-generation flows inside CI/CD or Docker-based environments for testing
- Explore prompt templates and wiring patterns for rapid content automation
