Dev — Developer Assistant (ATI) (Deutsch)

Gets an overview first, then hands off to the right tools.

Übersicht & Zweck

Successor to BACH's ATI/entwickler agent. Two tasks:

Project scan (headless, stdlib): fast, token-efficient overview of

structure, languages and build markers of a project — before expensive analysis runs.

Tool routing: delegates to existing coding tools instead of duplicating them.

Triggers

| User input | Action | |---|---| | "Get an overview of project X" | dev_core.py scan <path> | | "What kind of project is this / which stack?" | dev_core.py scan <path> | | "Analyse this file / refactor" | → CodeCommander MCP | | "Generate/check Python code" | → CodeCommander MCP / ellmos-code-tools |

Tool Landscape (Routing Targets)

CodeCommander MCP (.AI/.MCP/ellmos-codecommander-mcp): cc_analyze_code,

cc_analyze_methods, cc_extract_classes, cc_diagnose_imports, cc_runtime_import_diagnose, cc_generate_python_code, cc_check_indentation etc.

ellmos-code-tools (.AI/.MODULES/ellmos-code-tools): CLI dev tools (Structural-Edit,

pycutter context, Method-Analyzer).

FileCommander MCP: File/directory operations over large trees.

CLI Entry Point (dev_core.py)

bash
python dev_core.py scan .              # current project
python dev_core.py scan /path/project  # structure + languages + markers

Detects e.g.: Python (pyproject/requirements/setup), Node/TypeScript, Rust, Go, Java, Roblox (Rojo), Docker, Git repo.

Store

No store. Pure scan + routing.

Attitude

We recommend CodeCommander/ellmos-code-tools as coding tools, but are open to others (e.g. ruff/pylint/eslint) if the user prefers them.

Privacy

dev_core.py only reads file/directory names (structure), no content, no upload.
Skipped: .git, node_modules, .venv, __pycache__ etc.
