yvgude/lean-ctx v3.9.8

on GitHub

Added

• Smart Read redirect for Cursor (auto mode).
  Native Read calls in Cursor are now transparently compressed via lean-ctx's
  auto mode — selecting the optimal compression (signatures, map, etc.) per
  file for 87-97% token savings. Windowed reads (offset/limit) remain verbatim
  (full-compact) to preserve line indexing. Validated by edit-probe PoC:
  StrReplace does NOT fire a Read PreToolUse, so the redirect is safe.
• Replace mode hardening for all agents.
  • Claude Code / CodeBuddy: content-aware CLAUDE.md block updates; Replace
    mode block is now correctly installed even when block version matches.
  • Codex: mode-aware pretooluse handler — denies Bash in Replace mode,
    rewrites in Hybrid mode. Removed dead install_codex_deny_hook.
  • Pi: propagates replace mode to extension config + dedicated
    PI_AGENTS_REPLACE.md template.
  • Qoder: deny hooks for Read|Grep|Glob in Replace mode + replace rules.
  • Crush / Hermes: mode-aware rules installation via replace_rules_content().
  • CodeBuddy added to REPLACE_AGENTS.
• lean-md addon integration (PR #721). External addon by @dasTholo —
  directive-driven Markdown for agent plans. Reverse-cut: renderer lives in
  dasTholo/lean-md, lean-ctx hosts only the thin surface (registry entry,
  LSP formatter routing, RenderTransform trait, .lmd.md raw read).
• SessionStart nudge improvements. Explicit ctx_read cache statistics
  for shared-mode hosts (Cursor); fixed stale ctx_semantic_search reference.

Fixed

• Cursor Read redirect regression (GH #1250 follow-up).
  install_cursor_deny_hook was re-adding the Read redirect that
  merge_cursor_hooks had removed, causing cli_full traffic with 0%
  compression (1.4M tokens wasted). Now correctly separated: Read → redirect
  (smart compression), Grep|Glob → deny.
• Cursor Glob deny. Added Glob to the deny matcher alongside Grep —
  forces use of ctx_glob instead of native Glob.
• Claude/CodeBuddy CLAUDE.md not updating in Replace mode. Block
  installer now checks content (not just version) to detect stale blocks.
• lean-md registry integration: "mcp" → "none". Invalid enum value
  from PR #721 corrected; IntegrationKind::parse("mcp") silently returned
  None.
• Codex integration test adjusted. agent_init_codex test updated from
  3 to 2 PreToolUse entries after removing the separate deny hook.

Changed

• redirect_read_args() now returns Vec<String> with dynamic mode
  selection instead of a fixed [&str; 4] array.
• refresh_agent_hooks() is now fully mode-aware — determines the
  recommended HookMode per agent and installs the correct artifacts.
• Removed PoC edit_probe handler (served its diagnostic purpose).

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.
