yvgude/lean-ctx v2.21.1 on GitHub

File-based CLI caching — lean-ctx read <file> now caches file content to ~/.lean-ctx/cli-cache/cache.json. Second and subsequent reads of unchanged files return a compact ~13-token cache-hit response instead of the full file content. This directly addresses Issue #65 (pi-lean-ctx zero cache hits) by enabling caching for CLI-mode integrations that don't use the MCP server.
Cache management — New lean-ctx cache subcommand with stats, clear, and invalidate <path> actions.
--fresh / --no-cache flag — Bypass the CLI cache for a single read when needed.
5-minute TTL — Cache entries expire after 300 seconds, matching the MCP server cache behavior.
MD5 change detection — Files are re-read when their content changes, even within the TTL window.
Max 200 entries — Oldest entries are evicted when the cache exceeds capacity.
6 new unit tests including integration test for full cache lifecycle.

Registered sandbox and loop_detection modules that were present on disk but missing from core/mod.rs.
