/install my-sg-invoice-parser
Description
Extract structured data from Malaysian & Singaporean invoices/receipts. SST/GST-aware. Supports BM/EN/CN.
Usage Guidance
This skill is suspicious because it advertises 'invoice parsing' but actually only provides paid access to tax rates; the actual parsing is delegated to the agent. Before installing: (1) Verify the publisher and origin — the SKILL.md points to an external Cloudflare worker (swmengappdev.workers.dev) rather than an official homepage. (2) Treat SKILLPAY_API_KEY as sensitive: confirm its scope and minimum privileges (use a limited/test key if possible). (3) Ask the publisher for the full billing/shared code (the '../../shared/billing' module used by the worker is not in the package) so you can inspect where charges go and what endpoints are called. (4) If you expect server-side parsing, do not rely on this skill — it will not accept invoice images/text for parsing. (5) Test with a low-value or test account and confirm the payment flow before using with real users or production credentials.
Capability Analysis
Type: OpenClaw Skill
Name: my-sg-invoice-parser
Version: 2.0.0
The skill is a legitimate utility for parsing Malaysian and Singaporean invoices, incorporating a monetization layer via a billing endpoint. The code in `src/index.ts` and `src/tax.ts` focuses on calculating tax rates and processing payments through a documented service, with no evidence of data exfiltration, unauthorized execution, or malicious instructions in `SKILL.md`.
Capability Assessment
Purpose & Capability
The skill is named and described as an 'Invoice & Receipt Parser' but the code and SKILL.md do not perform automated parsing of invoices. The runtime endpoint (/parse) only charges via SkillPay and returns tax rates; Step 2 explicitly tells the agent to 'use your own capabilities' to extract structured data. That makes the published name/description misleading: consumers might expect the skill to accept invoice images/text and return parsed JSON, but it does not.
Instruction Scope
SKILL.md instructs posting user_id to an external worker endpoint that charges and returns tax rates, and then tells the agent to parse invoices locally. The instructions do not request unrelated files or extra environment variables. However, the endpoint domain (my-sg-invoice-parser.swmengappdev.workers.dev) and billing flow mean calling the skill will bill the user; the docs indicate a payment_url may be returned on failure. There is no step that uploads invoice content to the skill, but the SKILL.md and code don't accept invoice data — parsing is performed client-side.
Install Mechanism
No install spec is provided (instruction-only install path), which is lower risk. Source includes code files and a wrangler.toml (Cloudflare Worker) but no packaged installer. The code imports '../../shared/billing' and '../../shared/types' which are not included in the manifest; that suggests reliance on platform-provided shared modules or omitted code — not an immediate security red flag, but it makes behavior at runtime partially opaque.
Credentials
Only SKILLPAY_API_KEY is required, which aligns with the skill's observable billing behavior. No unrelated credentials or filesystem paths are requested. That single credential is proportionate to the described payment/charging function, but it is sensitive and grants the skill the ability to charge via the SkillPay integration.
Persistence & Privilege
always is false and the skill does not request any elevated or persistent platform-wide privileges. There is no indication it modifies other skills or system-wide settings.
