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 many high and medium patterns, but review found markdown documentation and Python examples, not executable skill code. The reported weak-crypto, C2, dynamic import, and shell-execution matches are false positives from survival-analysis terminology, fenced code blocks, and inline backticks. No prompt injection, data exfiltration, command execution, or malicious intent was found.

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.

Markdown code examples misclassified as shell execution

The external command findings are false positives. The cited lines are markdown inline backticks or fenced Python examples that document scikit-survival usage and are not executed by the skill.

The reviewed locations are markdown documentation and Python snippets. No shell command invocation, subprocess use, or runtime execution path is present.

Low

SKILL.md:37-43 references/competing-risks.md:19-23 references/evaluation-metrics.md:146-152 references/svm-models.md:29-37

Survival analysis terms misclassified as high-risk indicators

High-risk findings for weak cryptography and C2 keywords are false positives caused by domain terms and variable names such as Cox models, CIF, IPCW, and auc2.

The suspicious tokens appear in ordinary survival-analysis explanations and model examples. The context does not reference cryptography, command-and-control behavior, or malware operations.

Low

SKILL.md:372-383 references/data-handling.md:43-50 references/evaluation-metrics.md:306-312

Python import blocks misclassified as dynamic imports

The dynamic import findings are false positives. The cited code blocks use normal Python import syntax for scikit-survival modules inside documentation examples.

The inspected lines are fenced Python examples with explicit library imports. They are not JavaScript import expressions and do not load user-controlled modules.

Low

SKILL.md:357-360

Documentation links to external resources

The hardcoded URL findings point to official scikit-survival documentation and repository links. They are static reference links and do not perform network requests.

The lines are plain markdown links to project documentation. There is no code that fetches these URLs or transmits user data.
