Email Subject Generator

AI-powered email subject line generator. Create subject lines that get opened.

Security Scan

The skill mostly does what it claims (generate subject lines) but contains mismatches and a hard-coded merchant key that mean you should review and understand payment/network behavior before installing.

Purpose & Capability

The code implements an email subject generator that drives a local 'sloan' agent and charges per use — which fits the skill description. However metadata/registry fields claim no required binaries or env vars while both the SKILL.md and index.js assume an OpenClaw agent/binary is available. That metadata mismatch is unexpected.

Instruction Scope

Runtime instructions and the CLI usage are narrowly scoped to generating subject lines and performing a payment. They do not request unrelated files or credentials. However SKILL.md references an OPENCLAW_GATEWAY_TOKEN fallback that is not used in the code, and the code invokes a local 'openclaw' binary (child_process.spawn) which grants that external binary control over generation — a scope dependency the registry didn't advertise.

Install Mechanism

There is no install spec; the package includes index.js and a package-lock. Dependencies are standard (axios). The package-lock shows dependencies resolved via a Tencent mirror, which is not necessarily malicious but is a nonstandard registry source to be aware of if you plan to run npm install in your environment.

Credentials

The skill does not request user secrets, but the code embeds a default SKILLPAY merchant key (sk_...) and will POST charges to https://api.skillpay.me. SKILL.md lists SKILLPAY_MERCHANT_KEY as optional (and an embedded key used by default) — so by default payments go to the author's merchant account. The OPENCLAW_GATEWAY_TOKEN variable is documented but not used in code. Hard-coded merchant credentials and the undocumented network billing behavior are disproportionate to what users might expect from a simple generator.

Persistence & Privilege

The skill does not request permanent presence (always:false) and does not modify system/other-skill configuration. It simply spawns a local process and makes network requests at runtime.

What to consider before installing

This skill will spawn a local 'openclaw' agent to produce subjects and will attempt to charge 0.001 USDT by POSTing to api.skillpay.me using a merchant key embedded in the code unless you run with --test or set SKILLPAY_MERCHANT_KEY to your own. Before installing or running: 1) Verify you have a trustworthy 'openclaw' binary and the 'sloan' agent locally (the skill spawns that binary — it's not enforced in registry metadata). 2) If you don't want charges going to the author's account, set SKILLPAY_MERCHANT_KEY to your own merchant key or run with --test to avoid payment. 3) Review/replace the hard-coded merchant key in index.js if you plan to use this in production. 4) Inspect dependency sources (package-lock) or run in a sandbox if you're uncomfortable with nonstandard registry mirrors. 5) Be aware that the local 'openclaw' process could contact external services itself — verify its behavior. If you want a lower-risk test, use the --test flag which skips payment.
