Description
Generate signature images via the Signus API and return image files for chat delivery. Use when asked for signature generation through Signus API.
Usage Guidance
This skill appears internally consistent: it needs Node.js, runs a bundled JS script, calls only https://api.signus.ai, and writes generated images into ~/.openclaw/media/signatures-font/. Before installing, verify you trust api.signus.ai and that running 'npm install' in the skill folder is acceptable in your environment. Because the registry didn’t include an automated install spec, the SKILL.md expects you (or your runtime) to run npm install — review package-lock.json and adm-zip's provenance if you require stricter supply-chain controls. Don’t send secrets in the JSON payloads; the skill does not handle Authorization headers, so if your deployment requires auth you should update the design rather than embedding credentials in inputs. Finally, if you want extra caution, run this skill in a restricted runtime/container since it performs network I/O and writes files to your home directory.
Capability Analysis
Type: OpenClaw Skill
Name: signus-signature-generator
Version: 1.0.2
The skill is designed to generate signature images via the Signus API (api.signus.ai). The core logic in scripts/generate_font_signatures.js handles API requests, ZIP extraction using the adm-zip library, and image downloads without any evidence of data exfiltration, shell execution, or unauthorized access to sensitive system files.
Capability Assessment
Purpose & Capability
Name/description match the included code and runtime instructions: the JS script POSTs to api.signus.ai, downloads image artifacts, and writes them to a media directory. No unrelated third-party services or credentials are requested.
Instruction Scope
SKILL.md clearly confines actions to preparing a Node.js runtime, invoking the bundled script, calling fixed Signus endpoints, extracting archives, and writing images under ~/.openclaw/media/signatures-font/. One operational note: the registry entry lists no install spec but the SKILL.md requires running 'npm install' in the skill folder before first run; this is a functional mismatch (not necessarily malicious) and means the skill will install adm-zip at runtime.
Install Mechanism
No automated installer in registry; dependencies are standard npm packages (adm-zip) pulled from the public npm registry as declared in package-lock.json. No downloads from unknown domains, no URL shorteners or extraction of remote archives beyond the expected ZIP responses from the Signus API.
Credentials
The skill declares and uses no environment variables or credentials. The code does read the user's home directory (to create an output folder) which is proportional to saving generated images. There are no requests for unrelated secrets or config paths.
Persistence & Privilege
Skill does not request always:true and has no special persistence behavior. It creates only its own media folder under the user's home and does not attempt to modify other skills or system-wide configuration.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install signus-signature-generator - After installation, invoke the skill by name or use
/signus-signature-generator - Provide required inputs per the skill's parameter spec and get structured output
