README (SKILL.md)
AI Diagram Generator — AnyGen
This skill uses the AnyGen CLI to generate diagrams and visual charts server-side at www.anygen.io.
Authentication
# Web login (opens browser, auto-configures key)
anygen auth login --no-wait
# Direct API key
anygen auth login --api-key sk-xxx
# Or set env var
export ANYGEN_API_KEY=sk-xxx
When any command fails with an auth error, run anygen auth login --no-wait and ask the user to complete browser authorization. Retry after login succeeds.
How to use
Follow the anygen-workflow-generate skill with operation type smart_draw.
If the anygen-workflow-generate skill is not available, install it first:
anygen skill install --platform \x3Copenclaw|claude-code> -y
Usage Guidance
This skill appears coherent: it uses the AnyGen CLI and an API key to generate diagrams server-side. Before installing, verify you trust the AnyGen service and the @anygen/cli npm package (check publisher, reviews, and release source). Treat the ANYGEN_API_KEY like any secret: avoid sending sensitive diagrams/data to the service, rotate the key if exposed, and consider creating a scoped key if AnyGen supports it. Note the skill may prompt a browser-based OAuth flow during auth and may install an additional AnyGen workflow skill at run-time as needed.
Capability Analysis
Type: OpenClaw Skill
Name: anygen-diagram-generator
Version: 3.0.0
The skill instructions in SKILL.md direct the AI agent to autonomously install additional software and skills using the command 'anygen skill install --platform <openclaw|claude-code> -y' if dependencies are missing. While this behavior is framed as a setup step for diagram generation via anygen.io, the practice of a skill triggering the installation of further unverified code/packages represents a high-risk capability that could be used for lateral movement or persistence.
Capability Assessment
Purpose & Capability
Name/description, required binary (anygen), and required env var (ANYGEN_API_KEY) all directly match the stated purpose of using the AnyGen service to generate diagrams.
Instruction Scope
SKILL.md instructs the agent to authenticate (anygen auth login / API key) and to invoke the AnyGen CLI and an AnyGen workflow skill. These instructions stay within diagram-generation scope. Minor note: it references another skill ('anygen-workflow-generate') and suggests installing it via the AnyGen CLI; that external dependency is not declared in the metadata but is reasonable for operation.
Install Mechanism
Install spec uses a Node/npm package (@anygen/cli) to provide the anygen binary, which is a standard approach. This is moderate-risk compared with instruction-only skills because it installs third-party code from a package registry; it's proportionate to the CLI requirement but users should trust the package and vendor.
Credentials
Only one credential (ANYGEN_API_KEY) is required and declared as the primary credential; that matches the described remote service usage and is proportionate.
Persistence & Privilege
Skill is not forced-always and does not request broad system or cross-skill config access. It does not claim to modify other skills' configs or system-wide settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install anygen-diagram-generator - After installation, invoke the skill by name or use
/anygen-diagram-generator - Provide required inputs per the skill's parameter spec and get structured output
Version History
v3.0.0
**Major update: Migrated to use the AnyGen CLI, significantly simplifying setup and diagram workflows.**
- Replaced all scripts and dependencies with the official @anygen/cli (`anygen`).
- Removed all local Python, Node, and Bash helper scripts.
- Updated prerequisites: only `anygen` CLI required (auto-installs via npm/yarn/pnpm as needed).
- Authentication now uses a simple web login or direct API key via the CLI.
- Diagram generation flows are now directed through the `anygen-workflow-generate` skill.
- Greatly simplified installation and usage instructions.
v1.3.5
- Clarified how diagram rendering libraries (Draw.io, Excalidraw) are fetched and executed in the local browser context.
- Added security guidance: users with strict data-isolation requirements should review rendering scripts or run them in a network-restricted environment.
- Updated details under "Security & Permissions" to improve transparency about library usage and local processing.
v1.3.4
anygen-diagram-generator 1.3.4
- Improved security/permissions documentation: specifies CDNs are only for static libraries, no diagram content is sent externally.
- Enhanced communication style: when showing `prepare` replies/prompts, preserve original wording as much as possible, translating only if needed—do NOT rephrase or summarize.
- User prompts for missing API keys now use proper Markdown link formatting for better usability.
- Added explicit declaration and requirements for `sessions_spawn` in metadata for background diagram monitoring.
- Workflow expanded from 4 to 5 phases, clarifying that the diagram plan prompt must be preserved and shown verbatim to the user for approval.
- Metadata, prerequisites, and capability fields refined for clarity and accuracy.
v1.3.3
- Added automated installation of Playwright and tsx (TypeScript runtime) dependencies for local PNG diagram rendering.
- Updated prerequisites in metadata: clarified Node.js is needed, and Node-based tools now auto-install.
- Revised Python and Node.js requirements in skill metadata for improved setup automation.
- Security section clarified: diagram rendering now uses Playwright and Chromium locally, and fetches diagram libraries from public CDNs.
- Minor improvements to the security, permissions, and prerequisites documentation for accuracy and clarity.
v1.3.2
anygen-diagram-generator 1.3.2
- Added modular Python scripts for authentication and file utilities (`scripts/auth.py`, `scripts/fileutil.py`)
- Updated main script logic in `scripts/anygen.py` to use new helpers
- Documented new file structure, behavior, and API security model
- Added `scripts/package-lock.json` for better Node.js dependency management
- Streamlined and clarified SKILL.md, especially around security, permissions, and background monitoring workflow
