Sample report
See a full Skarn report before you run one
This is the exact HTML report skarn assess -o report.html writes -
self-contained, fully redacted, generated over Skarn's synthetic reference corpus: the last two
hours of Claude Code work on a busy developer machine, seeded with format-valid but non-functional
credentials and one staged attack. Every finding, severity, chain, and score below is genuine
detector output.
Open it, explore the risk score, the severity facets, and the correlated attack chain - then run the same one command on your own machine.
What you are looking at
The corpus is hand-authored and every credential in it is fake, but nothing in the report is mocked: the findings, severities, the attack chain, and the 83/100 risk score are what Skarn's shipping detection engine produced from those sessions.
Skarn's report format never carries a raw secret: credentials are masked to a fixed form that hides their length, and PII reveals zero characters. What you see here is exactly what a report you share with your security team looks like.
The report is a single HTML file. It loads no external resources and makes no network requests - the same local-only property as the scanner that wrote it. Your own report stays on your machine unless you choose to share it.
Read it like an operator
The 0-100 score aggregates severity, chain evidence, and credential liveness signals per session. Two hours of work on this machine scores 83: six critical and thirteen high findings across five sessions.
One multi-stage chain was correlated, running reconnaissance to exfiltration to poisoning across MITRE ATLAS tactic-aligned stages - the pattern a plain secret scanner cannot see.
Filter by severity. Each finding names the rule, the session, and the redacted value - enough to rotate the credential, never enough to leak it again.
Your machine, in one command
Skarn scans the local session logs of Claude Code, Codex CLI, Cursor, Gemini CLI,
and GitHub Copilot. No account, no configuration, no upload. The sample scopes to two hours
of one assistant; plain skarn assess scans everything.
skarn assess -o report.html writes your own copy of the report you just opened.
