Highest confirmed finding severity

Low

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 reported shell execution, weak cryptography, reconnaissance, and network indicators, but the referenced files are Markdown documentation and TypeScript examples. I found no executable scripts, no command execution path, no credential handling, no prompt injection text, and no malicious intent; remaining concerns are documentation-only false positives.

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.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
resources/implementation-playbook.md:335-343resources/implementation-playbook.md:713-715
Documentation-Only Network References
Network indicators are illustrative API-client type examples and external learning links. The API client method has a placeholder implementation and no HTTP client import, fetch call, or data transmission.
The API-client section demonstrates type-safe method signatures and returns a placeholder value. The URLs are static references to TypeScript documentation resources, not runtime endpoints.

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 (3)

False Positive: Markdown Backticks Flagged as Shell Execution
The static analyzer flagged Markdown backticks and TypeScript code fences as Ruby or shell execution. These lines are documentation examples and resource references, not executable skill code.
The referenced content is Markdown around TypeScript examples and inline resource paths. The skill contains only SKILL.md and a Markdown playbook, with no executable script file or shell invocation.
Low
SKILL.md:3-15resources/implementation-playbook.md:14resources/implementation-playbook.md:508
False Positive: Weak Cryptography Pattern Not Present
High-severity weak cryptography alerts point to descriptive text and form-validation examples. I did not find MD5, SHA1, hashing, encryption, or cryptographic API usage in the referenced files.
The cited lines discuss TypeScript use cases and simple string validation. There is no evidence of weak cryptographic algorithms or security-sensitive hashing behavior.
Low
resources/implementation-playbook.md:265-272resources/implementation-playbook.md:303resources/implementation-playbook.md:666
False Positive: Reconnaissance Terms Are Type Examples
System reconnaissance alerts point to TypeScript examples for event emitters, API routes, state handling, and best practices. No system inspection commands or host enumeration behavior are present.
The referenced snippets are TypeScript teaching examples. I found no commands, filesystem traversal, process inspection, or environment probing.

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