Summary
On Windows 11, after about two weeks of normal daily use, claude-smart filled my C: drive. The cause is ~/.reflexio: it had grown to 1.0 TB across 47.7 million files, leaving 6.7 GB free on a 1.9 TB drive (99.6% full). This is a new laptop. It came within a few GB of being unbootable.
Root cause
.reflexio creates one folder per session (Cu<id>), and each one holds a full copy of the plugin's Python and Node runtime rather than a reference to a shared install. One session folder I opened was 1.56 GB, containing:
torch_cpu.dll 293 MB
next-swc.win32-x64-msvc.node 130 MB
chromadb_rust_bindings.pyd 60 MB
torch_cpu.lib 28 MB
libscipy_openblas (x2) ~38 MB
torch_python.dll, libvips ~36 MB
onnxruntime (.dll + pybind) ~33 MB
typescript.js (x2), lightningcss, cygrpc, sleef, ...
That is the entire PyTorch + ChromaDB + ONNX + Next/TypeScript stack duplicated into every session, and never cleaned up.
The math
- 671
Cu* session folders (dated 5/18 to 6/1, matching my session history)
- ~1.5 GB each
- 1,010 GB total, 47,717,635 files, 5,320,897 folders
- 671 x 1.5 GB is the whole terabyte
Impact
- Free space fell to 6.7 GB, then 2.4 GB mid-cleanup, on a 1.9 TB disk.
- Uninstalling did NOT reclaim the space. It removed the code and left the 1 TB of data in
~/.reflexio.
- Deleting 47.7M files via PowerShell
Remove-Item was unusably slow; I had to wipe it with a multithreaded robocopy /MIR.
Expected behavior
- Install the runtime once and share it across sessions (symlink/junction, a single venv + node_modules, or one long-lived backend) instead of copying gigabytes per session.
- Garbage-collect old session folders (keep last N, or prune by age/total size).
- Enforce a hard size cap on
~/.reflexio, and warn before it grows large.
uninstall should offer to remove ~/.reflexio.
Severity
Critical: unbounded disk growth with no cap, no cleanup, and no warning, ending in near disk-exhaustion and a genuine data-loss / unbootable risk. For a heavy daily user it fills a terabyte in roughly two weeks.
Environment: Windows 11, Claude Code, claude-smart (installed via the plugin marketplace, ~late May 2026).
