render-lab-tasks-langsmith
Unreleased Python port: 12 registered tasks from render-lab/render-tasks. Python 3.12+, Render SDK 1.0.1. Requires core 0.1.1 or later.
From the repository root:
uv sync --all-packages --locked
Import render_lab_tasks_langsmith.tasks to register tasks. The package root is inert.
Compose the exported app with Workflows.from_workflows; call tasks through
ctx.run. Every operation also exports *_impl(ctx, input, *, deps=None) for
injection. Client(http, env) accepts a caller-owned HTTPX client, and
Deps(langsmith=client) injects it. Default dependencies open and close the HTTP
client per invocation; credentials are read lazily at use. No HTTP retries or
background vendor polling occur; retry.py owns the durable retry policies.

Typed JSON inputs and results are in types.py. Task names and JSON field names
match the pinned source; Python function names use snake_case.
Environment
| Variable | Requirement |
|---|---|
LANGSMITH_API_KEY |
Required at first API call. |
LANGSMITH_ENDPOINT |
Optional; https://api.smith.langchain.com by default. |
LANGSMITH_WORKSPACE_ID |
Optional workspace ID; forwarded as x-tenant-id for all requests. |
Behavior and limits
Uses direct HTTP, including the multipart example endpoint described by langsmith 0.8.1. Upsert lookup filters the requested stable IDs, avoiding the source first-page existence bug. list_examples defaults to a bounded 1000-row page and supplies nextOffset. LANGSMITH_WORKSPACE_ID applies to REST and SDK-replacement paths. These deliberate differences are recorded in ADR-0010. The source uses both SDK paths and /api/v1 REST paths; account routing and multipart support remain unverified. Review progress currently consumes one feedback response; vendor pagination and gate counts across different runs need live validation.
Verification
All registered tasks have hermetic contract fixtures executed independently against
the pinned TS implementation. SDK-backed tasks also have explicit HTTP request
fixtures. See tests/test_batch3_contracts.py and tests/test_batch3_edges.py.
These are not live vendor results.
Vendor webhooks subpaths and other registration-free TS exports are outside this batch unless explicitly listed above. Full registered-task coverage does not imply all supporting exports are ported.
Pending scopes, test resources, replay, and hosted checks are in the live-testing backlog and verification tracker.
Webhook adapter
render_lab_tasks_langsmith.webhooks.langsmith_engine_adapter(on_event, ...) returns a
registration-free adapter for render_lab_triggers. The callback receives the
verified event and returns {"task": "namespace.task", "args": [event]} or None.
The signing credential LANGSMITH_ENGINE_WEBHOOK_SECRET is read inside verification unless
provided explicitly. Importing this module does not register tasks. Signature
checks use the raw body; live delivery remains in the testing backlog.
