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.

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

Static analysis reported many command, network, environment, and weak-crypto patterns, including one critical heuristic combination. Review found these are Markdown examples, Data Commons API calls, installation commands, official documentation links, and API key setup guidance; no malicious intent, prompt injection, credential exfiltration, or hidden executable code 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.

Expected Network Use for Public Data Queries

The network-related detections are expected because Data Commons queries public API endpoints and links to official Data Commons resources. No evidence found of data exfiltration to unrelated endpoints.

The network behavior is semantically aligned with the skill purpose: querying Data Commons data. The reviewed URLs and API examples point to Data Commons documentation and services.

Low

SKILL.md:216-226 references/getting_started.md:13-17

API Key Setup Requires Normal Secret Care

The skill documents use of DC_API_KEY and direct api_key initialization for Data Commons authentication. This is legitimate, but users should prefer environment variables and avoid pasting keys into prompts or shared files.

The environment access references are documentation for an expected API key, not code that reads or transmits secrets. The risk is limited to user handling of credentials.

Risk findings

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

No confirmed security findings were recorded for this completed audit.

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 (2)

External Command Matches Are Documentation Examples

The command patterns are Markdown examples for installing the Data Commons client and setting an environment variable. They are not hidden execution logic, but users should review package installation commands before running them.

The matched lines are fenced Markdown examples, and no file contains scripts or executable wrappers. The only real action is optional package installation shown to the user.

Low

SKILL.md:3-13 references/node.md:5-12 references/resolve.md:9-13

Weak Crypto Detections Are False Positives

The weak cryptography alerts align with prose, example identifiers, or naming patterns in documentation. No evidence found of MD5, SHA1, DES, or other weak algorithms being implemented or recommended.

Manual review of the cited areas found Data Commons descriptions and entity resolution terms, not cryptographic code. No supporting evidence was found for a real weak-crypto finding.

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