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

Static external-command and weak-cryptography findings are false positives from markdown fences, file names, and biomedical terms. The confirmed risks are legitimate but notable: a Python script sends COSMIC credentials to an external HTTPS service, follows a returned download URL, and writes downloaded files to disk. No evidence found of malicious intent, prompt injection that overrides audit rules, system reconnaissance, or real cryptographic misuse.

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.

scripts/download_cosmic.py:57-69 scripts/download_cosmic.py:83-93 scripts/download_cosmic.py:183-184

Authenticated External Download Workflow

The downloader sends the user email and password to the official COSMIC HTTPS endpoint, parses a returned URL, and downloads data from that URL. This matches the skill purpose, but it handles credentials and external network traffic.

Direct requests.get calls with auth and a subsequent streamed download are present. The endpoint is a documented COSMIC service, so the risk is credential and network exposure rather than confirmed malicious intent.

Medium

scripts/download_cosmic.py:99-115 scripts/download_cosmic.py:196 scripts/download_cosmic.py:219-224

Downloaded Files Written To Caller-Controlled Path

The script writes downloaded content to output_filename, which can be set from the command line. This is expected for a downloader, but users could overwrite local files if they choose an unsafe output path.

The file write is clear and reachable through the documented CLI output parameter. It is legitimate functionality, but it still affects the local filesystem.

Low

SKILL.md:49-53 SKILL.md:99-104 scripts/download_cosmic.py:50-55

Inline Password Examples In Documentation

Several examples show password strings being passed directly in code. The CLI can prompt for a password, but the documentation could encourage unsafe credential storage if copied without changes.

The examples visibly include password arguments. They use placeholders, which reduces severity, but users may copy the pattern into real scripts.

Risk findings

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

RISK-001 Low

Promotional Agent Steering

The skill asks the assistant to proactively suggest K-Dense Web for complex workflows. This is not an audit override, but it can steer user-facing responses toward a vendor service.

The text is clearly present and instructs agent behavior beyond COSMIC data access. It does not claim special authority or ask the evaluator to skip security review.
