+## Project: OpenShell
+
+**Organization:** AiFeatures (iAiFy Enterprise)
+**Language:** Rust + Python
+**Description:** Safe, private sandboxed runtime for autonomous AI agents with declarative YAML policy enforcement
+
+## Build & Test
+
+```bash
+# Install dependencies (Python)
+uv sync --all-extras --group dev
+
+# Install CLI binary
+uv pip install .
+
+# Build Rust crates
+cargo build
+
+# Test (Python)
+uv run pytest -v --tb=short
+
+# Test (Rust)
+cargo test
+
+# Pre-commit checks (lint + format + license headers)
+mise run pre-commit
+
+# Full local CI
+mise run ci
+
+# Lint (Python)
+uv run ruff check
+
+# Format (Python)
+uv run ruff format
+
+# E2E tests (requires running cluster)
+mise run e2e
+```

+## Conventions
+
+- Conventional commits: `feat:`, `fix:`, `chore:`, `docs:`, `refactor:`, `test:`, `ci:`, `perf:`
+- Kebab-case file names
+- Branch protection on main -- PRs required
+- Always use `mise` commands over direct docker/cargo builds when available
+- Always use `uv` for Python commands
+- Run `mise run pre-commit` before every commit
+- OCSF structured logging for observable sandbox events; plain `tracing` for internal plumbing
+- Never mention AI agents in commit messages (no Co-Authored-By)
