Fixed

  • Instruction files no longer compressed — SKILL.md, AGENTS.md, RULES.md, .cursorrules, and files in /skills/, /.cursor/rules/, /.claude/rules/ are now always delivered in full mode, bypassing all heuristic/bandit/adaptive mode selection. This was the root cause of agents losing instructions after v3.4.7 when the Intent Router was introduced. Guards added in 5 code paths: resolve_auto_mode, predict_from_defaults, select_mode_with_task, auto_degrade_read_mode, and CLI read_cmd. Fixes #159 regression, resolves GlemSom's report.
  • Markdown files exempt from aggressive compression — .md, .mdx, .txt, .rst files no longer fall into the aggressive default bucket in predict_from_defaults. These file types return None (= full mode) to prevent stripping prose/instruction content.
  • Windows Claude Code PowerShell compatibility — Claude Code hook matchers now include PowerShell|powershell on Windows, so PreToolUse hooks fire regardless of whether Claude uses Bash or PowerShell. Rewrite script also accepts PowerShell tool names. Fixes #192.

Added

  • is_instruction_file() public API — Reusable guard function detecting instruction/skill/rule files by filename and path patterns. Used across MCP, CLI, and server dispatch paths.
  • Lean4 formal proofs — Theorems 12-13 in ReadModes.lean: instruction files always resolve to full mode, content is always preserved.
  • 7 new regression tests — instruction_file_detection, resolve_auto_mode_returns_full_for_instruction_files, defaults_never_compress_markdown, and PowerShell hook matcher tests.

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.
