+
+Guidance for coding agents working in `posthog-python`.
+
+## Repo context
+
+- This repository contains the PostHog Python SDK, published as `posthog`.
+- The main runtime package is `posthog/`; tests live under `posthog/test/`.
+- The project uses `uv` for local development. See `CONTRIBUTING.md` for setup.
+- Keep edits targeted and follow existing patterns. Prefer adding or updating tests near the behavior you change.
+
+## Validation
+
+Useful checks:
+
+```bash
+uv run ruff format --check .
+uv run ruff check .
+uv run mypy --no-site-packages --config-file mypy.ini . | uv run mypy-baseline filter
+uv run pytest --verbose --timeout=30
+uv run python -W error -c "import posthog"
+```
+
+For focused changes, run the smallest relevant `uv run pytest ...` command first.
+
+If public API surface changes, update/check `references/public_api_snapshot.txt` with:
+
+```bash
+make public_api_snapshot
+make public_api_check
+```
+
+## `posthoganalytics` mirror package
+
+This repo also publishes `posthoganalytics`, a generated mirror of `posthog` used by the PostHog app. The mirror is created by copying `posthog/` to `posthoganalytics/` and rewriting absolute imports such as `from posthog.foo import ...` to `from posthoganalytics.foo import ...`.
+
+Important when editing SDK-internal code:
+
+- Prefer relative imports for imports within the SDK package, especially in runtime modules under `posthog/`.
+  - Good: `from .client import Client`, `from .exception_utils import extract_exception_properties`
+  - Risky: `from posthog.client import Client`
+- Absolute `posthog...` imports inside SDK modules can break the `posthoganalytics` mirror when it is imported inside an application that also has its own `posthog` package/module on `sys.path`.
+- Test mirror-sensitive changes by running the normal focused tests and, when relevant, `make prep_local` to generate a local `posthoganalytics` copy for testing in the PostHog app.
+- Do not commit generated `posthoganalytics/` directories; they are build/local artifacts.
+
+## Release/build notes
+
+- `make build_release` builds the `posthog` distribution.
+- `make build_release_analytics` builds the `posthoganalytics` distribution and temporarily rewrites/copies package files; ensure the working tree is clean before and after running it.
+- Release flow publishes both packages; see `RELEASING.md`.
