Signus Signature Generator

Generate signature images via the Signus API and return image files for chat delivery. Use when asked for signature generation through Signus API.

Signus Font Signature

User-facing language

• Always write user-facing text in English unless the user explicitly asks for another language.

Runtime requirements

• Node.js 18+.
• Install dependencies in this skill folder before first run:

cd /home/node/.openclaw/workspace/skills/signus-font-signature && npm install

Inputs

Provide exactly one identity source:

• name (e.g., "Allon Mason"), OR
• firstName + lastName, OR
• initials (e.g., "AM")

Optional:

• count — max number of images to return.

Validation

• Accept exactly one identity source.
• Reject empty/blank values.
• If count is provided, treat as numeric limit.

Run

node /home/node/.openclaw/workspace/skills/signus-font-signature/scripts/generate_font_signatures.js '<json payload>'

Examples:

node /home/node/.openclaw/workspace/skills/signus-font-signature/scripts/generate_font_signatures.js '{"name":"Allon Mason","count":10}'

node /home/node/.openclaw/workspace/skills/signus-font-signature/scripts/generate_font_signatures.js '{"firstName":"Allon","lastName":"Mason"}'

Detailed execution flow

1. Parse payload and normalize identity into name.
2. Create output directory:
   • ~/.openclaw/media/signatures-font/<name>-<timestamp>/
3. Request font generation using fixed trusted host (https://api.signus.ai) and endpoint order:
   • primary: POST /api/signus/v0/signature-generations/font
   • fallback: POST /api/signus/v0/users/me/signature-generations/font
4. Process response by content-type:
   • ZIP/octet-stream: extract with in-process JS unzip library (adm-zip), then collect image files.
   • JSON: read payload.thisPageItems[], then download each image from:
     • /api/signus/v0/signature-generations/font/{generationId}/signatures/{generatedSignatureId}/{clean|watermark}.png
5. Return:
   • count
   • directory
   • signatures[]: { id, filePath }
6. Send images to chat via message action=send and media=<filePath>.

Authentication model

• This skill does not handle API tokens or env-based credentials.
• It assumes the primary public endpoint can be used without explicit Authorization header.
• The /users/me/... fallback may work only where implicit session/auth exists.
• If your deployment requires explicit auth, update the script design first (do not inject secrets into payloads by default).

Security notes

• No environment-variable reads.
• No shell command execution.
• Network target is fixed to https://api.signus.ai.
• Writes only under ~/.openclaw/media/signatures-font/.
• Keep this skill focused on Signus API signature generation and chat-ready image outputs.
