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.

The static external command, script, and weak cryptography findings are false positives from Markdown code fences, inline API names, and FCS channel keywords. No prompt injection, credential access, network exfiltration, or malicious execution intent was found in SKILL.md or references/api_reference.md. The remaining risk is limited to expected local file parsing and export behavior.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
SKILL.md:41-53SKILL.md:450-468SKILL.md:476-499
Local File Read and Export Guidance
The skill teaches reading FCS files and writing FCS or CSV outputs. This is expected for the skill, but users should process trusted files and choose controlled output paths.
The file operations are core to FCS handling and are not malicious. The residual risk is ordinary local file processing risk for malformed inputs or unintended output paths.

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)

Static External Command Findings Are Markdown False Positives
The reported backtick execution locations are Markdown code fences, inline identifiers, and normal Python examples. They do not instruct the agent to run shell commands beyond a standard package installation example.
The cited lines are visible Markdown examples and API documentation. No shell interpolation, command construction, or user-controlled execution path is present in the reviewed files.
Low
SKILL.md:3SKILL.md:150-152references/api_reference.md:227-230
Static Weak Cryptography Findings Are FCS Keyword False Positives
The weak cryptography alerts match FCS terminology such as PnN, PnS, PnR, and PnE, plus the skill description. These are flow cytometry metadata fields, not cryptographic algorithms.
The surrounding context defines FCS channel labels and amplification metadata. I did not find hashing, encryption, signature verification, or password storage logic.

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