Description
SignNow API integration with managed OAuth. E-signature platform for sending, signing, and managing documents.
Use this skill when users want to upload documents, send signature invites, create templates, or manage e-signature workflows.
For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).
Requires network access and valid Maton API key.
Usage Guidance
This skill is internally consistent: it proxies SignNow calls through Maton and only asks for a MATON_API_KEY. Before installing, verify you trust Maton (gateway.maton.ai / ctrl.maton.ai) because the gateway will see and act on your requests and tokens. Treat MATON_API_KEY as sensitive: limit its scope if possible, use a dedicated/rotatable key, and review Maton's documentation and privacy/security posture. If you expect calls to go directly to signnow.com (not via a proxy), confirm that behavior with the skill author; otherwise the Maton proxy is functioning as designed.
Capability Analysis
Type: OpenClaw Skill
Name: signnow
Version: 1.0.2
The skill bundle appears benign. All code examples and instructions in `SKILL.md` are directly related to integrating with the SignNow API via the `maton.ai` gateway, requiring a `MATON_API_KEY` from environment variables. Network calls are exclusively directed to `https://gateway.maton.ai` and `https://ctrl.maton.ai`. File access is limited to reading a specific `document.pdf` for upload, which aligns with the skill's purpose. There is no evidence of data exfiltration to unauthorized third parties, unauthorized command execution, persistence mechanisms, obfuscation, or prompt injection attempts designed to subvert the agent's core function. The ability to set a `callback_url` for webhooks is a standard API feature, not an inherent malicious act by the skill itself.
Capability Assessment
Purpose & Capability
Name/description (SignNow e-signature integration) align with the SKILL.md examples: calls to gateway.maton.ai and ctrl.maton.ai implement SignNow operations (upload, invites, templates). Required env var (MATON_API_KEY) matches the described managed-OAuth gateway usage.
Instruction Scope
Runtime instructions are concrete and limited to: calling Maton gateway endpoints, reading MATON_API_KEY from env, and optionally reading local files when uploading documents. There are no instructions to read unrelated system files, other credentials, or to exfiltrate data to third-party endpoints beyond Maton/SignNow proxies.
Install Mechanism
No install spec and no code files beyond SKILL.md and LICENSE — instruction-only skill; nothing is written to disk or fetched during install.
Credentials
Only one required environment variable (MATON_API_KEY) is declared and used in examples. That credential is appropriate for a gateway-based API integration; no unrelated secrets or config paths are requested.
Persistence & Privilege
No special persistence requested (always=false). The skill is user-invocable and may be called autonomously by the agent (default), which is expected for skills and is not in itself a red flag.
How to Use
- Make sure OpenClaw is installed (local or Docker)
