+# Copilot Instructions
+
+## Project overview
+
+- FastAPI service that mimics FlareSolverr-style API for bypassing anti-bot pages using Camoufox + Playwright captcha solver.
+- Entry point: main app in main.py; routes and request flow defined in src/endpoints.py and src/models.py.
+- Browser lifecycle is owned by get_camoufox() in src/utils.py, which yields a page, solver, and context for each request.
+
+## Architecture and data flow
+
+- Request flow: POST /v1 -> read_item() -> browser.goto() -> wait for load states -> detect challenge title -> solve captcha -> return LinkResponse.
+- Challenge detection uses CHALLENGE_TITLES from src/consts.py; update this map when adding providers.
+- Health check hits /v1 internally with <https://google.com> and fails if status is not OK.
+- Logging: LogRequest middleware logs only POST /v1 timing and outcome; other paths pass through.
+
+## Key modules and patterns
+
+- Models use Pydantic v2 with camelCase aliasing for responses (see src/models.py).
+- LinkResponse.invalid() is the standard error response shape; keep fields consistent with FlareSolverr style.
+- get_camoufox() constructs AsyncCamoufox with addons and optional proxy config from env vars.
+
+## Config and environment
+
+- Core env vars in src/consts.py: HOST, PORT, PROXY_SERVER, PROXY_USERNAME, PROXY_PASSWORD, LOG_LEVEL, VERSION.
+- VERSION strips leading "v" for tag-style values.
+
+## Developer workflows
+
+- Local run: uv sync && uv run main.py
+- Init mode: uv run main.py --init (pre-warms health check via browser setup)
+- Tests: uv sync --group test && uv run pytest --retries 3
+- Docker troubleshooting: docker build --target test .
+
+## Tests and external dependencies
+
+- tests/main_test.py calls real websites; tests are network-dependent and may be skipped based on upstream status.
+- HTTP client tests use starlette.testclient + httpx; avoid mocking unless needed for local-only changes.
