v3.4.7

Added

• ctx_call meta-tool — compatibility tool for MCP clients with static tool registries (e.g. Pi Coding Agent). Invoke any ctx_* tool by name via a stable schema without requiring dynamic tools/list refresh. Fixes #174.
• Interactive Graph Explorer — ctx_graph action=export-html generates a self-contained, interactive HTML visualization with pan/zoom, node selection, transitive highlighting, and PNG export.
• Self-Hosted Team Server — lean-ctx team serve enables shared context across workspaces with token-based auth, scoped permissions, rate limiting, and audit logging.

Changed

• Dual-format hook output — lean-ctx hook rewrite/redirect now emits a combined JSON response compatible with both Cursor (permission/updated_input) and Claude Code (hookSpecificOutput). All IDEs that support PreToolUse hooks now work with the same command.
• JetBrains config format — ~/.jb-mcp.json now uses the official mcpServers snippet format matching JetBrains AI Assistant documentation (was: nonstandard servers array).
• Shell hook block markers — lean-ctx init --global now writes stable # lean-ctx shell hook — begin/end markers, making updates idempotent and safe across reinstalls.

Fixed

• Claude Code hooks not intercepting subagent calls — extract_json_field in hook handlers was too rigid for pretty-printed or spaced JSON from Claude Code. Now robustly handles all formatting styles. Fixes Discord report.
• Claude Code hooks overwriting other plugins — install_claude_hook_config now merges PreToolUse hooks instead of replacing the entire matcher group, preserving hooks from other plugins (e.g. obra/superpowers).
• lean-ctx doctor false positive "pipe guard missing" — on Windows Git Bash with XDG config paths, doctor now correctly detects shell hooks in both ~/.lean-ctx/ and ~/.config/lean-ctx/ directories, with both forward and backslash path separators. Fixes Discord report.
• Pi Coding Agent array parameters — get_str_array now accepts JSON-encoded strings (e.g. "[\"a\",\"b\"]") in addition to native JSON arrays, fixing ctx_multi_read for the Pi MCP bridge. Fixes #173.
• Windows CI test failure — workspace_config tests now use serde_json::json! for path serialization, preventing invalid JSON escapes on Windows.

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.
