Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

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.

This skill is documentation-only (markdown guide). Static analyzer flagged 119 patterns in code examples, but all are FALSE POSITIVES. The skill teaches legitimate npm/git workflows. Minor risk: documents sudo usage and credential handling patterns, but explicitly recommends secure practices (env vars over hardcoded tokens, SSH over passwords).

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Capability review items (2)
Medium
SKILL.md:196
Documentation References sudo Commands
The skill documents sudo usage for fixing npm permissions (line 196). While this is legitimate system administration, users could misuse sudo. The skill does recommend safer alternatives (~/.npm-global).
sudo commands present in documentation examples, but skill explicitly recommends non-sudo alternatives as preferred approach
Low
SKILL.md:174-186
Documents Credential Handling Patterns
The skill documents GitHub token usage and SSH key setup. While it recommends secure practices (env vars, SSH), providing these patterns could be misused if users don't follow the security guidance.
Credential patterns documented but skill explicitly recommends secure handling via environment variables and SSH keys

Risk findings

Confirmed security concerns are separated from items that still need review.

Analysis metadata

Audit model: claude

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 (3)
Low
SKILL.md:28-377
Static Analyzer False Positives - Command Patterns in Documentation
61 'external_commands' detections are markdown code examples, not executable skill code. Pattern matches like $(whoami) and backticks are bash examples in documentation context.
All detected patterns are in markdown code blocks - this is documentation teaching users commands, not a skill that executes code
Low
SKILL.md:29-361
Static Analyzer False Positives - URL Patterns
23 'network' detections are documentation URLs (github.com, npm docs, stackoverflow) and git URL examples. These are reference links, not network calls made by the skill.
URLs are documentation references and git URL syntax examples, not actual network requests
Low
SKILL.md:84-202
Static Analyzer False Positives - Filesystem Paths
24 'filesystem' detections include /tmp paths, ~/.ssh, ~/.npmrc references. These are documentation examples showing where npm/git store files, not actual file operations by the skill.
File paths appear in documentation examples explaining npm/git behavior, not skill file operations

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
