What Claude Code stores on your machine (and how to see it)

Claude Code keeps a lot of data in ~/.claude/ that most people never look at. I wanted to know what was there, so I built a scanner. On my machine it found: 76 persistent memory files across 10 projects 4,445 session transcripts totaling 1.8GB 2.2GB total data footprint The memory files are markdown with frontmatter, organized by type: what Claude thinks your role is, feedback you've given, project context, reference links. It remembers more than you'd expect. The tool npx agentlens scan No API keys, no accounts. Reads local files only. Scan commands agentlens memory — what Claude remembers about you agentlens costs — token usage by model and project agentlens features — active feature flags on your account agentlens sessions — transcript stats and tool usage agentlens privacy — total data footprint Action commands agentlens clean --dry-run — preview which memories would be deleted agentlens redact — find secrets that leaked into memory files agentlens diff save — snapshot current stat
