projtool

Status: M0–M5 complete, plus the post-M5 v3→v4 container-layout refactor. 34 MCP tools shipped; ~1970 unit + ~110 integration tests. The full MNIST workflow (retrofit → experiment → train → report → image build) runs end to end. See docs/development/M1-M5-roadmap.md for milestone detail.

projtool is a Python package + Claude Code MCP server that supports a single ML researcher running experiments across a local development machine and remote AutoDL GPU containers.

A retrofitted project lives under a single container directory (v4 layout):

• <container>/code/main/ — the git repo holding model code. Each experiment gets an exp/<topic> branch in a sibling worktree under <container>/code/.

• <container>/output/ — training products (metrics, figures, manifests). Synced from the remote via mutagen, large binary artifacts filtered out.

• <container>/docs/ — an independent git repository holding analysis reports, organized by code-repo branch namespace; cross-branch summaries go in summary/.

• <container>/data/ — datasets (may be a symlink to a NAS path).

Day zero: the user runs projtool setup once. From then on, every action goes through mcp__projtool__* tool calls in Claude Code: experiment creation, training launch, run polling, report writing, AutoDL instance lifecycle, and project-image builds.

The assets/ tree is data, not code. It gets packaged with the wheel and read at runtime via importlib.resources, then copied into user projects during retrofit. See CLAUDE.md for the asset/code boundary.

Development

Requires Python 3.11+.

git clone <this-repo>
cd projtool
python -m venv .venv
source .venv/bin/activate                   # Linux/macOS
# .venv\Scripts\activate                    # Windows
pip install -e ".[dev]"
pytest
