yvgude/lean-ctx v3.6.19 on GitHub

Added

Built-in passthrough profile: No output modification — always full content, zero compression. Use via LEAN_CTX_PROFILE=passthrough or lean-ctx config set profile passthrough. Includes default_mode=full, crp_mode=off, degradation.enforce=false, pipeline: all false, max_tokens_per_file=10M, max_context_tokens=1M.
Persistent profile selection via config.toml: New profile field in config.toml provides a fallback when LEAN_CTX_PROFILE env var is not set. Resolution order: env var → config.toml → "coder" default. Set via lean-ctx config set profile <name>.
Profile config schema entry: lean-ctx config show now displays the profile key.

Fixed

LEAN_CTX_FULL_TOOLS=0 incorrectly treated as ON: is_ok() only checked existence, not value. Now =0 and =false are correctly treated as disabled.
mode=full returning stubs/deltas in passthrough mode: handle_full_with_auto_delta ignored no_degrade and passthrough profiles. Cache stubs and auto-deltas are now skipped when no_degrade=true or when the active profile has default_mode=full + crp_mode=off.
MCP schema claimed default mode was full: The ctx_read tool description said "default: full" but the actual default was auto (resolved by AutoModeResolver). Agents that omitted the mode argument got compressed output instead of full content. Schema now correctly states "default: auto".
Silent fallback to coder profile: When LEAN_CTX_PROFILE pointed to a non-existent profile name, lean-ctx silently fell back to coder without any warning. Now logs a tracing::warn with the missing profile name and creation instructions.

Upgrade

lean-ctx update                 # recommended (auto-downloads + refreshes shell hooks)
cargo install lean-ctx          # or
npm update -g lean-ctx-bin      # or
brew upgrade lean-ctx

Note: After upgrading via cargo/npm/brew, run lean-ctx setup to refresh shell aliases. lean-ctx update does this automatically.
