## Your user gave you this repository to understand their own project

OntologyEX helps you explain **their** repository, product, business, or company:
what it is, who it serves, how money moves, the main journeys, where it breaks, and
what nobody wrote down. Every claim you make links to the lines it rests on. The
tools only read their repository; they run and change nothing in it.

1. **Get the kit** (Python 3.11 or newer; `KIT` is wherever you can write):

   ```bash
   git clone --depth 1 https://github.com/New1Direction/OntologyEX.git KIT
   python3 -m venv KIT/.venv
   KIT/.venv/bin/python -m pip install 'PyYAML==6.0.3'
   ```

   On Windows use `KIT\.venv\Scripts\python`.

2. **Scan their repository** (`REPO`). This reads files only:

   ```bash
   KIT/.venv/bin/python KIT/ontology-extraction/scripts/overview.py scan \
     --repo REPO --out REPO/.ontologyex/overview
   ```

3. **Read and write**, following
   [business overview](ontology-extraction/references/business-overview.md): read the
   docs and the `read_first` files the scan lists, then fill in
   `REPO/.ontologyex/overview/blueprint.json`: purpose, audiences, value, money flows,
   journeys, risks, unknowns, improvements, each with citations and a basis.

4. **Build the page**:

   ```bash
   KIT/.venv/bin/python KIT/ontology-extraction/scripts/overview.py build --repo REPO \
     --blueprint REPO/.ontologyex/overview/blueprint.json --out REPO/.ontologyex/overview/business.html
   ```

5. **Tell them**: the page path, then what it is, how money moves, the main
   journeys, where it breaks, and what is unknown, with a file reference or two each.
   Say it is your reading of the sources, linked so they can check it.

Then offer what fits:

- **Their systems, live:** `KIT/.venv/bin/python KIT/ontology-extraction/scripts/operate.py up --repo REPO`
  opens a local map; `feed_setup.py` adds health checks and `otel_setup.py` adds
  traces between services, one command per service with no code change (see
  [operating picture](ontology-extraction/references/operating-picture.md)).
- **Change one workflow safely:** build a domain skill for it
  ([guided onboarding](ontology-extraction/references/guided-onboarding.md)).
- **Keep the kit in their project:** `KIT/.venv/bin/python KIT/ontology-extraction/scripts/install.py --project REPO`
  installs it as a Claude Code skill.

Rules: read, do not run their code or install their dependencies; never send their
source anywhere; ask before anything that downloads (`otel_setup.py run` installs
OpenTelemetry from npm or PyPI on first use) or writes outside `REPO/.ontologyex`;
when the sources do not say, write it down as unknown instead of guessing.

## Working on OntologyEX itself

- Python tools: `ontology-extraction/scripts/`; the Rust engine: `engine/`.
- Tests: `python -m unittest discover -s tests` (Python 3.11+, `PyYAML==6.0.3`).
- Rust: `cargo test --locked --manifest-path engine/Cargo.toml`; Rust must give the
  same answers as Python: `python tests/rust_feeds_parity.py engine/target/debug/ontologyex-feeds`
  and `python tests/rust_discover_parity.py engine/target/debug/ontologyex-discover`.
- Tools propose; a person decides. Nothing writes to production or authorizes actions.
