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.

Open current Skill page

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

Most static findings are false positives from bundled font license text, Apache license text, and design prose. The Ruby or shell backtick finding is markdown formatting around a directory path, not command execution. A medium-risk issue remains because the skill tells the model to download any needed fonts without trusted-source or approval guardrails.

Capability review items (1)
Medium
SKILL.md:110
Unbounded External Font Download Instruction
The skill instructs the model to download whatever fonts are needed. This can trigger arbitrary external network access and introduce untrusted font files unless sources and user approval are constrained.
The instruction explicitly permits downloads, but no destination or exfiltration endpoint is specified. The risk is uncontrolled network access and supply-chain exposure, not confirmed malicious behavior.

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 (3)
Low
LICENSE.txt:4LICENSE.txt:196canvas-fonts/BigShoulders-OFL.txt:1-5
Bundled License URL Findings Are False Positives
The hardcoded URL findings point to Apache and SIL Open Font License references. These are documentation links in license text, not executable network calls or data transfer logic.
The cited lines are license notices and source references. No code path consumes these URLs or sends data to them.
Low
SKILL.md:3SKILL.md:47LICENSE.txt:61canvas-fonts/BigShoulders-OFL.txt:44canvas-fonts/BigShoulders-OFL.txt:81
Weak Crypto And Reconnaissance Matches Are False Positives
The weak cryptography and system reconnaissance matches occur in ordinary design wording, Apache license clauses, and SIL license terms. No cryptographic API, hashing operation, host inspection, or reconnaissance behavior was found in the reviewed context.
The matched text is natural language or standard license language. The skill contains instructions and font assets, not executable crypto or system probing code.
Low
SKILL.md:108
Markdown Backtick Command Finding Is A False Positive
The external command finding is caused by markdown backticks around a local directory name. It does not invoke a shell or interpolate user input.
Line 108 uses inline code formatting for ./canvas-fonts. There is no command syntax, shell execution directive, or dynamic argument construction.
