Security Scan

The skill's instructions, lack of installs, and absence of required credentials are consistent with an instruction-only invoice generator that drafts invoices and reminder text — it does not request unexplained access or perform hidden actions.

Purpose & Capability

Name and description (invoice creation, calculations, reminders) match the SKILL.md content. The skill requires no binaries, env vars, or installs, which is proportionate for an instruction-only drafting/formatting skill.

Instruction Scope

Instructions stay focused on generating invoice text, layouts, and reminder drafts. The README and SKILL.md claim 'tracks outstanding invoices and sends payment reminders' but provide no mechanism or credentials for sending emails or connecting to payment processors — the skill appears limited to drafting and tracking artifacts conceptually, not performing network actions. References to local files (references/*.md) exist but those files are not included; this is a documentation gap, not an immediate security concern.

Install Mechanism

No install spec and no code files — lowest-risk instruction-only skill. Nothing is downloaded or written to disk by the skill package itself.

Credentials

The skill requests no environment variables, credentials, or config paths. There are no unexplained secret requests or access demands that would be disproportionate to invoicing functionality.

Persistence & Privilege

always is false and autonomous invocation is allowed by default (normal). The skill does not request persistent system-wide changes or cross-skill configuration; no elevated presence is requested.

Assessment

This skill is instruction-only and appears to only draft invoices and reminder text — it does not actually send emails or process payments on its own. If you expect automated sending or payment collection, you'll need to supply integrations (SMTP, Stripe, etc.) and corresponding credentials; verify any integration before providing secrets. Note the SKILL references missing docs (references/*.md) — ask the author or inspect updated files if you need those templates. As always, install only skills from sources you trust and avoid granting credentials unless you understand exactly which external service the skill will use.

• Include clear payment instructions
• Send invoices within 24 hours of project completion
• Follow up on overdue invoices at 1, 7, and 14 days past due
• Pair with a cost tracking system for profit calculations
