What problem does it solve?
You received a PDF you cannot trust and need a repeatable way to inspect its internals without treating “open in Preview” as your only option.
Who is it for?
Indie developers hardening upload flows, doing security coursework, or triaging one-off malicious PDF samples with peepdf on a trusted lab machine.
Skip if: Teams that need automated SOC pipelines, legal e-discovery, or analysis of non-PDF malware families without PDF-specific tooling.
When should I use this skill?
You have an untrusted PDF and need structured peepdf-oriented inspection steps for security triage.
What do I get? / Deliverables
You leave with a peepdf-focused inspection plan and clearer signals about whether the PDF warrants deeper sandbox analysis or quarantine.
- Peepdf inspection command sequence
- Notes on suspicious PDF objects or streams to escalate
- Quarantine or sandbox recommendation
Recommended Skills
Journey fit
Malicious-document analysis belongs on the Ship shelf under security because it supports pre-release and incident response review of risky user uploads and phishing payloads. Security subphase covers artifact triage, IOC extraction, and understanding embedded JavaScript or streams before you ship upload features or respond to abuse.
How it compares
Use for PDF-centric peepdf triage, not as a substitute for full browser E2E automation skills like Playwright CLI.
