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.

Static analysis reported external command, weak cryptography, and reconnaissance patterns. Manual review found instructional Markdown, Python preprocessing examples, and ML terminology, with no executable shell logic or malicious intent.

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.

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 (4)

False Positive: Python Examples Flagged as Shell Execution
The flagged references/preprocessing.md locations are fenced Python examples for imputation, scaling, encoding, feature engineering, outlier handling, and pipelines. No shell command execution or command interpolation is present.
The reviewed locations are Markdown code fences containing ordinary Python data science snippets. I found no subprocess, shell, network, or secret handling behavior in those examples.
Low
SKILL.md:178-187SKILL.md:206-208
False Positive: Backtick Formatting Flagged as Commands
The SKILL.md locations use Markdown backticks for a model directory tree and reference file names. This is documentation formatting, not command execution.
The flagged text is inside a Markdown code block or inline Markdown formatting. It contains paths and file names, not runnable shell instructions.
Low
SKILL.md:3-5
False Positive: Weak Cryptography Pattern
The SKILL.md description is plain metadata about machine learning workflows. No cryptographic algorithm, hash function, cipher, or credential handling appears at the flagged location.
The flagged location contains only the skill description text. The weak cryptography alert has no semantic support in the reviewed content.
Low
SKILL.md:68SKILL.md:98
False Positive: System Reconnaissance Pattern
The flagged SKILL.md locations contain ML feature and tuning terms, including geospatial features and grid search. They do not request host, network, user, process, or environment reconnaissance.
The surrounding context is machine learning feature engineering and hyperparameter tuning. I found no commands or instructions for gathering system information.

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