Static analysis reported many high-risk patterns, but review shows the weak-cryptography and most external-command hits are LaTeX or Markdown false positives. The confirmed risk is a legitimate Bash PDF review script that invokes local PDF utilities on a user-supplied file; no malicious intent, prompt injection, data exfiltration, or hidden network behavior was found. Publish with a warning to run command-line checks only on trusted files.

Shell Examples In Documentation
Many external-command detections are Markdown examples for compiling LaTeX, checking logs, and inspecting generated PDFs. These examples are relevant to the skill and do not execute automatically, but users should review commands before running them.
The cited locations are documentation or fenced code examples rather than hidden execution paths. The risk is user-mediated command use, not automatic execution.

Placeholder URLs In Poster Templates
Hardcoded URL findings are DOI, GitHub, and design-tool links used for QR codes or reference resources. They are visible template content and not evidence of network calls, tracking, or data exfiltration.
The URLs appear in LaTeX QR-code examples and reference lists. No code path was found that fetches these URLs or sends local data to them.

Reconnaissance Detections Are Defensive Checks Or Poster Terms
System and network reconnaissance detections are command-availability checks, PDF inspection commands, or ordinary poster-design text. No evidence was found of host inventory collection, port scanning, credential discovery, or outbound probing.
The script check uses command -v before running optional PDF tools, and other examples are normal documentation content. I did not find semantic evidence of reconnaissance intent.

Local PDF Review Script Uses External Commands
The repository includes a Bash script that runs local tools such as pdfinfo, pdffonts, pdfimages, ls, grep, awk, head, tail, wc, and tr against a user-supplied PDF path. The file path is quoted and the commands are read-only, so command injection was not found, but parsing untrusted PDFs with local utilities is still an operational risk.
The shell script clearly invokes external PDF inspection utilities on a user-provided file. The commands are hardcoded and arguments are quoted, which lowers confidence that this is exploitable or malicious.

Weak Cryptography Detections Are LaTeX False Positives
The high-severity weak cryptography detections resolve to LaTeX font commands, poster section text, statistics notation, Markdown headings, package names, and generated audit text. No cryptographic implementation or weak hash usage was found in the reviewed locations.
Representative flagged lines contain LaTeX or Markdown content, not crypto APIs. The pattern class is not semantically applicable to this poster-template skill.
