Highest confirmed finding severity

1 confirmed security finding requires attention.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Static analysis flagged command examples, parent-directory links, and weak-crypto patterns. The command findings are legitimate Gmail CLI usage, the parent-directory references are documentation links, and no cryptographic code or prompt injection was found. Risk remains medium because authenticated Gmail commands can read, send, and manage sensitive email data.

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:18-20SKILL.md:52-58SKILL.md:60
Authenticated Gmail CLI Operations
The skill instructs users to run `gws gmail` and `gws schema` commands. This is expected for a Gmail CLI skill, but authenticated commands can read, send, and manage mailbox data.
The command examples are explicit and semantically tied to Gmail account operations. They are legitimate documentation, but the authenticated mailbox scope creates real operational risk.
Needs review findings (1)
REVIEW-001 Medium
SKILL.md:16SKILL.md:26-32
Cross-Directory Skill Dependencies
The skill references a shared skill file and helper skill files through parent-directory paths. These references are not arbitrary path traversal, but marketplace packaging should ensure adjacent files are trusted.
The parent-directory paths are visible and fixed Markdown references. They are likely safe documentation links, but they intentionally depend on files outside this skill directory.

Analysis metadata

Audit model: codex

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Static false positives ignored (2)
Low
SKILL.md:4SKILL.md:24
Weak Cryptography Static Matches Are False Positives
Static analysis reported weak cryptographic algorithm patterns on the description and table header lines. No evidence of hashing, encryption, or cryptographic API usage was found in the skill file.
The cited lines contain plain documentation text, not code. There is no semantic evidence of weak cryptographic behavior.
Low
SKILL.md:16SKILL.md:18-20SKILL.md:26-32SKILL.md:38-46SKILL.md:52-60
Ruby Backtick Static Matches Are Markdown Formatting
The reported Ruby backtick executions are inline Markdown code spans and fenced shell examples. The skill file does not contain Ruby code or dynamic command construction.
The cited content is Markdown documentation and command guidance. No executable Ruby file or shell interpolation behavior exists in the scanned file.
