yvgude/lean-ctx v3.5.0 on GitHub

Added

Context OS Runtime — full integration of shared sessions, event bus, and SSE endpoints for real-time multi-agent collaboration. Agents can subscribe to context changes, broadcast events, and share session state across workspaces.
Daemon Mode — persistent background daemon with CLI-first dispatch. lean-ctx daemon start/stop/status manages the process. All CLI commands route through the daemon for sub-millisecond response times and shared state.
Context Package System — versioned, shareable context bundles with lean-ctx pack create/list/info/export/import/install/remove/auto-load. Package layers (knowledge, gotchas, config, graph) enable portable project intelligence.
Context Field Theory (CFT) — unified model for context management with Context Potential Function, Rich Context Ledger, Context Overlay System, Context Handles, and Context Compiler.
Provider Framework — pluggable provider system with GitLab integration and caching layer for external context sources.
Autonomy Drivers — configurable agent autonomy levels with intent routing and degradation policies.
Context IR — intermediate representation for context compilation, enabling cross-provider optimization.
Instruction Compiler — lean-ctx instructions command compiles project-specific rules into optimized agent instructions.
Context Proof System — lean-ctx proof generates verifiable context provenance chains for audit trails.
Team Server: Context OS scopes — SessionMutations, Knowledge, and Audit scopes for fine-grained team permissions via lean-ctx team token create.
Qoder & QoderWork support — new editor integration for Qoder IDE. PR #180 by @zsefvlol.
56 MCP tools — exposed all registered tools for installed agents, including new ctx_verify, ctx_proof, ctx_provider, ctx_artifacts, ctx_index tools. Fixes #176.
38 Context OS integration tests — comprehensive test suite covering multi-client concurrency, event bus, shared sessions, and SSE endpoints.
Windows OpenCode guide — step-by-step manual for OpenCode on Windows 10. PR #181 by @HamedEmine.

Changed

CLI-First Architecture — all new modules (daemon, providers, instruction compiler, proof, overview, knowledge, compress, verify) are accessible as CLI subcommands, reducing MCP schema overhead.
Server Refactor — modular tool registry with ToolTrait, pipeline stages, and per-tool dispatch for cleaner extensibility.
A2A alignment — ScratchpadEntry now aligns with A2AMessage types for cross-agent interoperability.
HTTP-MCP contract — extended with full Context OS API surface documentation.
Shell pattern library — expanded to 95+ output compression patterns including clang, fd, glab, just, ninja.
Property Graph — enhanced with metadata layer and reproducibility contract.

Fixed

CLI relative path resolution — paths are now resolved to absolute before sending to the daemon, preventing "file not found" errors when working directory differs.
install.sh POSIX compliance — rewritten as pure POSIX sh so curl | sh works on dash (Ubuntu/Debian default). PR #175 by @narthanaj.
Qoder MCP config — added LEAN_CTX_FULL_TOOLS to Qoder configuration for complete tool exposure. Includes clippy fixes.
Team SSE endpoint — removed dead code and properly wired audit_event into the SSE stream.

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.
