Security audit

LYGO Champion: kairos herald of time

Security checks across malware telemetry and agentic risk

Overview

This is a deprecated persona/reference pack with local-only reference files and helper scripts, with no evidence of hidden data access, exfiltration, persistence, or destructive behavior.

Installing this mainly adds a deprecated persona pack and its local reference files. Prefer the listed successor skill for new use, and only run the included Python helper scripts if you want to check the packaged hash or file presence.

Category
MCP Least Privilege
Confidence
88% confidence
Finding
The skill references local files such as `references/canon.json` and other `references/*` artifacts, which implies file-read behavior without any declared permissions or explicit disclosure. Even if the reads are limited to package-local files, undeclared capability creates a trust gap and can lead users or tooling to underestimate what the skill accesses.

Tp4

High
Category
MCP Tool Poisoning
Confidence
92% confidence
Finding
The skill presents itself primarily as a deprecated persona helper, but its documented/derived behavior includes validation of local files, parsing metadata, checking verifier docs, and extracting a hash value. This mismatch is dangerous because users may invoke or trust the skill as harmless legacy content while it performs additional integrity-checking and file-inspection actions that were not clearly declared.
