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 produced many high and critical alerts, but review found they are false positives from Markdown backticks, scientific target names, molecular property acronyms, and documentation URLs. The remaining publishable risk is low because the skill includes runnable PyTDC example scripts and expected external dataset or documentation access, with no evidence of credential handling, shell execution, obfuscation, exfiltration, or prompt injection.

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)
Low
scripts/load_and_split_data.py:1scripts/benchmark_evaluation.py:1scripts/molecular_generation.py:1
Runnable example scripts load external scientific datasets
The skill bundles Python scripts for PyTDC workflows. They do not invoke shells or handle secrets, but running them may trigger PyTDC dataset access and local caching through the PyTDC library.
The files are executable Python examples and import PyTDC dataset or oracle classes. The observed behavior is legitimate scientific data access, not command execution or credential exfiltration.
Low
SKILL.md:454-456references/utilities.md:681-684scripts/benchmark_evaluation.py:268
Documentation includes external project links
Hardcoded URLs point to TDC documentation, benchmark pages, and related project resources. These are expected reference links, but users should know the skill directs them to external sites.
The URLs are visible documentation references to tdcommons.ai, readthedocs.io, and GitHub. I found no evidence that secrets or local data are sent to these locations.

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 (1)
Low
SKILL.md:351-362scripts/benchmark_evaluation.py:55scripts/molecular_generation.py:320-326
Static high-severity terms are scientific false positives
Terms flagged as C2 keywords, weak cryptography, or private-key access are biological targets, molecular metrics, dictionary keys, and seed variables used in PyTDC examples.
The surrounding context shows DRD2, GSK3B, QED, SA, and keys are PyTDC domain concepts or normal Python operations. No cryptographic implementation, C2 behavior, or certificate material is present.
