This report does not block or authorize the manifest or ZIP.

AI review found that most static findings are false positives from Markdown code fences, PubChem API path examples, and chemistry identifiers such as SMILES and InChI. Confirmed risks are legitimate external network access to PubChem and optional file downloads that can overwrite caller-selected paths. No prompt injection, credential exfiltration, shell 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.

Confirmed security concerns (2)

RISK-001 Medium

External Network Access to PubChem
The helper script builds PubChem and PUG-View URLs and performs GET or POST requests. This is expected for the skill, but users should understand that compound names, CIDs, SMILES, targets, and assay identifiers are sent to PubChem.
Network calls are directly present and target public PubChem endpoints. The intent appears legitimate, with no evidence of credential or local data exfiltration.
RISK-002 Medium
scripts/compound_search.py:220-236SKILL.md:181-183SKILL.md:193-204
Download Helper Can Overwrite Files
The compound download helper passes a caller-provided filename to PubChemPy with overwrite enabled. This is useful for structure export, but unsafe callers could overwrite files if they pass unintended paths.
The overwrite behavior is explicit in the helper and examples. Risk depends on caller control of filenames, so this is a publishable concern rather than malicious behavior.

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)

External Command Alerts Are Markdown False Positives
The static analyzer interpreted Markdown code fences and inline backticks as Ruby or shell backtick execution. The cited locations are documentation examples, not executable shell command construction.
The reviewed locations are Markdown fences, API route examples, or prose. No subprocess, os.system, shell=True, or equivalent command execution was found.

Weak Cryptography Alerts Are False Positives
The high blocker alerts resolve to chemistry and API documentation text, including SMILES, InChI, InChIKey, GET routes, and PUG-View. No cryptographic algorithm implementation or security-sensitive hashing was found.
The static hits do not correspond to crypto APIs or digest operations. The surrounding context is chemical identifier documentation and PubChem endpoint text.

System Reconnaissance Alerts Are Benign Workflow Text
The reconnaissance alerts point to loop limits, result counting, troubleshooting, and example output for PubChem workflows. They do not inspect host users, processes, filesystems, network interfaces, or environment variables.
The reviewed code handles PubChem result sets and prints example assay information. No host reconnaissance behavior was identified.
