+# CLAUDE.md — UiPath LLM Client
+
+## Project Overview
+
+This is a Python monorepo providing a unified client for UiPath's LLM services. It has two published packages:
+
+- **`uipath-llm-client`** (core) — located at `src/uipath/llm_client/`. Core HTTP client with auth, retry, and provider-specific clients (OpenAI, Google, Anthropic).
+- **`uipath-langchain-client`** (langchain) — located at `packages/uipath_langchain_client/`. LangChain-compatible chat models and embeddings, depends on the core package.
+
+Supported backends: **AgentHub** (default), **LLMGateway**, and **Orchestrator**.
+
+---
+
+## Development Setup
+
+Uses [uv](https://docs.astral.sh/uv/) with workspace support.
+
+```bash
+uv sync --all-extras
+```
+
+Run tests:
+```bash
+pytest tests
+```
+
+Lint and format:
+```bash
+ruff check
+ruff format --check
+pyright
+```
+
+Tests use VCR cassettes (SQLite, `tests/cassettes.db`) via `pytest-recording`. HTTP is recorded and replayed; real network calls are not made in CI.
+
+---

+

+
+## Versioning Rules
+
+Both packages follow semantic versioning. The CD pipelines trigger on version changes in the respective `__version__.py` files.
+
+### When core client changes
+
+Update **all** of the following:
+
+1. `src/uipath/llm_client/__version__.py` — bump core version
+2. `packages/uipath_langchain_client/src/uipath_langchain_client/__version__.py` — bump to same version
+3. `packages/uipath_langchain_client/pyproject.toml` — update the `uipath-llm-client >= X.Y.Z` dependency to match the new core version
+4. `CHANGELOG.md` — add entry under new version
+5. `packages/uipath_langchain_client/CHANGELOG.md` — add entry under new version
+
+### When only langchain changes
+
+Update **only**:
+
+1. `packages/uipath_langchain_client/src/uipath_langchain_client/__version__.py` — bump langchain version
+2. `packages/uipath_langchain_client/CHANGELOG.md` — add entry under new version
+
+Do **not** touch the core `__version__.py` or root `CHANGELOG.md` for langchain-only changes.
+
+---
+
+## CHANGELOG Format
+
+Follow the existing format — newest version first, grouped by date:
+
+```markdown
+## [X.Y.Z] - YYYY-MM-DD
+
+### Added / Fixed / Changed
+- Description of the change
+```
+
+---
+
+## PR Guidelines
+
+### Before Opening a PR
+
+- Run `ruff check`, `ruff format --check`, and `pyright` — all must pass.
+- Run `pytest tests` — all tests must pass.
+- Apply versioning rules above: the CI workflow (`ci_change_version.yml`) enforces that any changed source files must have a corresponding version bump and changelog entry.
+
+### PR Scope
+
+- Keep PRs focused. One logical change per PR.
+- If a change touches both core and langchain, that is a single PR — both packages version together.
+- Do not mix version bumps with unrelated refactors.
+
+### What to Include in the PR Description
+
+- What changed and why.
+- Which package(s) are affected (core, langchain, or both).
+- Reference any related issues.
+
+### Dev Builds
+
+Add the `build:dev` label to a PR to trigger a dev package publish to TestPyPI. The PR description will be updated automatically with install instructions.
+
+---
+
+## Code Style
+
+- **Formatter/linter:** ruff (config in root `pyproject.toml`)
+- **Type checker:** pyright (strict)
+- **Python version:** 3.11+ required, 3.13 used in CI
+- StrEnum string comparisons are acceptable — do not replace with enum constants.
+- Provider clients live under `clients/<provider>/` in both the core and langchain packages.
+- Settings use pydantic-settings with `BaseSettings`; do not add ad-hoc config.
+
+---
+
+## CI/CD Pipelines
+
+| Workflow | Trigger | Purpose |
+|---|---|---|
+| `ci.yml` | PR to main | Lint, type check, run tests |
+| `ci_change_version.yml` | PR to main | Validate version bump + changelog |
+| `cd.yml` | Push to main (core version change) | Build + publish core to PyPI |
+| `cd-langchain.yml` | Push to main (langchain version change) | Build + publish langchain to PyPI |
+| `publish-dev.yml` | PR with `build:dev` label | Publish dev build to TestPyPI |
+
+The langchain CD waits for the core package to appear on PyPI before building, since it depends on it.
