Bugs fixed:
- files.py: use typed error checking (_raise_for_status) instead of raw
raise_for_status(), ensuring WrennNotFoundError etc. are raised
correctly
- exceptions.py: check both "capsule_ids" and "sandbox_ids" response
keys
for backwards compatibility
- code_interpreter: retry _ensure_kernel on 5xx errors (only fail on
4xx),
remove redundant TimeoutError in bare except, clean up non-standard
top-level msg_id/msg_type from Jupyter messages
Resource leaks fixed:
- capsule.py: close WrennClient if capsule creation or init fails
- code_interpreter: add close()/__del__ for _proxy_client cleanup when
not using context manager
Logic fixes:
- pty.py: yield exit events to callers instead of silently discarding
them
- capsule.py: auto-resume paused capsules in wait_ready instead of
failing
- capsule.py: log warnings on destroy failure in __exit__ instead of
silently swallowing errors
- Update Woodpecker to run unit and integration tests in parallel
- Add GitHub Actions workflow for PyPI trusted publishing on main
- Add license, classifiers, keywords, and URLs to pyproject.toml
- Fix ruff lint errors (unused imports, duplicate class name) and formatting
Replace the WrennClient-centric API with a top-level Capsule class that
mirrors e2b's Sandbox interface, enabling drop-in migration. Key changes:
- Capsule/AsyncCapsule with direct construction (reads WRENN_API_KEY and
WRENN_BASE_URL env vars), namespaced sub-objects (capsule.commands,
capsule.files), dual instance/static lifecycle methods via _DualMethod
descriptor (capsule.kill() and Capsule.kill(id))
- WrennClient simplified to API-key-only endpoints (capsules, snapshots);
JWT-based resources (auth, hosts, teams) removed
- wrenn.code_interpreter submodule with Capsule subclass defaulting to
code-runner-beta template and run_code() support
- Sandbox alias emits FutureWarning instead of DeprecationWarning

Introduces the core Wrenn client and a dedicated sandbox execution
environment. This includes automated model generation and a custom
exception hierarchy to support robust integration.
- Add `WrennClient` in `src/wrenn/client.py` for API interaction.
- Implement `Sandbox` in `src/wrenn/sandbox.py` for isolated execution.
- Add Pydantic/model support via `_generated.py`.
- Define project-specific error types in `exceptions.py`.
- Include AGENTS.md documentation for specialized logic.
- Add comprehensive unit and integration tests.
- Update build system (Makefile, uv.lock, pyproject.toml) and LICENSE.
