lesscoder 0.1.1

Code-Native Engine MVP CLI (Java-focused) with local orchestrator and adapter workflow.

lesscoder

Code-Native Engine for local AI-assisted coding workflows.

This repository provides an end-to-end loop:

Analyze -> Plan -> Execute -> Verify -> Done

Core Modules

• ALSP (Rust): repository map, symbol lookup, LSP fallback
• ALSP_ADAPTER (Rust): local protocol service over TCP
• Patchlet (Rust): atomic Search/Replace patch apply with backup and rollback
• Orchestrator (Python): LangGraph-based pipeline and repair routing
• CLI (lesscoder): run tasks, query trace, start server

Requirements

• Python 3.11+
• Java 17+
• Maven 3.9+
• Rust toolchain (currently required for lesscoder server)

Install

After package publish:

pip install lesscoder
npm i -g @lesscoder/cli

From source (development):

pip install -e .

The npm package is a CLI wrapper that invokes the Python runtime.

lesscoder server runtime mode:

• Dev mode: if local Rust manifest exists, use cargo run.
• Installed mode: if no manifest, resolve adapter binary from:
  • LESSCODER_ADAPTER_BIN
  • bundled binary (if packaged)
  • local cache ~/.lesscoder/adapter/...
  • GitHub Release auto-download (default repo: MoCuishlei/less-coder)
  • checksum verify via lesscoder_adapter_manifest.json when available

Run

lesscoder warmup --project-root /abs/path/to/your/repo
lesscoder server --host 127.0.0.1 --port 8787
lesscoder run --project-root /abs/path/to/your/repo
lesscoder trace --trace-id <trace_id>
lesscoder release-dry-run --project-root /abs/path/to/your/repo --tag v0.1.0

warmup requires explicit path parameters (--project-root or --manifest-path). server can start without project path, then accept system.warmup(project_root=...) later.

MCP Setup

Start the service first:

lesscoder server --host 127.0.0.1 --port 8787

When server starts, it prints:

• a ready-to-copy MCP config JSON snippet
• HTTP inspect endpoints:
  • http://127.0.0.1:8787/health
  • http://127.0.0.1:8787/methods

Then configure your MCP client to launch lesscoder as a local server process. Example config (common mcpServers format):

{
  "mcpServers": {
    "lesscoder": {
      "command": "lesscoder",
      "args": ["server", "--host", "127.0.0.1", "--port", "8787"]
    }
  }
}

Notes:

• project activation is explicit via system.warmup payload (project_root/path).
• If port 8787 is already occupied, change it in both server args and client settings.
• Current adapter endpoint is 127.0.0.1:<port> with local protocol v0.
• Browser inspection endpoints are best-effort diagnostics; MCP calls still use local protocol v0.
• You can override adapter binary path with LESSCODER_ADAPTER_BIN.
