Email Writer

Professional email writing assistant with tone adjustment, template library, grammar checking, and response suggestions. Supports formal, casual, persuasive,...

Security Scan

The skill is mostly an instruction-only email writing guide, but it advertises runtime features (APIs, analytics, tracking) without any implementation or required credentials—this mismatch is incoherent and worth caution.

Purpose & Capability

The SKILL.md describes runtime APIs (EmailWriter class, compose/adjustTone/generateReply/findTemplates/trackPerformance/getInsights) and analytics/tracking features that normally require a backend or integrations with email services, but the package contains no implementation files and the skill declares no required credentials or config. That mismatch between claimed capabilities and the actual footprint is incoherent.

Instruction Scope

The instructions themselves are benign prose and code examples that show how to call an API; they do not instruct the agent to read local files, access environment variables, or exfiltrate data. However, they are open-ended about analytics/trackPerformance behavior (what data is sent where is unspecified), which could hide external calls in an implementation that isn't present here.

Install Mechanism

No install spec and no code files to execute (instruction-only). This is the lowest-risk install pattern from a supply-chain perspective.

Credentials

The skill requests no environment variables or credentials despite describing features (analytics, tracking, email performance metrics) that normally need access to email accounts, analytics backends, or API keys. The absence of any declared credentials is inconsistent with the advertised functionality.

Persistence & Privilege

The skill does not request always: true and uses default autonomy settings. There is no indication it will modify other skills or system-wide settings.

What to consider before installing

This skill is an instruction-only email-writing guide — it contains usage examples for an EmailWriter API but provides no implementation files or install steps. That means: (1) it cannot actually send emails or collect analytics as-written — the features shown are illustrative, not functional; (2) if you expect runtime integrations (tracking/open rates, inbox access), ask the publisher for the actual implementation and a clear description of what external services it calls and what credentials are required; (3) package.json references a main file but no index.js is included — another sign the published bundle is incomplete; (4) allowing the agent to autonomously invoke skills is normal, but don’t grant this skill additional credentials or install untrusted code until you verify where analytics/metrics are processed and whether any network endpoints are contacted. If you want to proceed, request the full source or a clear security/data-flow description from the owner before installing or granting access to mailboxes or API keys.
