Detection Coverage

132 detections mapped to MITRE ATLAS 5.6 (including the agentic techniques: context poisoning, agent config modification, credentials from agent config, exfiltration via tool invocation) and ATT&CK. Generated from the binary; enforced by tests.

Install

Portable raw binaries for USB / air-gap, install.sh, Homebrew tap, go install. SHA256 and Sigstore verification, and why unsigned downloads prompt on macOS and Windows.

Claude Code Forensic Artifacts

Every on-disk location, the JSONL session schema, interpretation and collection commands.

Case Explorer

agentdfir serve: agent tree, density-scrubber timeline, the raw transcript line behind every event, findings and topology — in your browser, loopback only, zero external resources.
