WalkthroughThis change adds the NVIDIA NeMo Fabric Remote Agent adapter for OpenAI and Anthropic HTTP APIs. It also adds Relay settings reuse, shared input normalization, package wiring, validation, tests, and documentation. ChangesRemote Agent adapter

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This change adds remote HTTP execution, but the current version can leave requests hanging indefinitely, reject some complete streamed responses, and break downstream imports that use existing settings names. These correctness, availability, and compatibility risks should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@adapters/README.md`:
- Line 68: Update the Complete FabricConfig Support and Runtime and
Observability Compatibility tables in the adapters README to include a Remote
Agent row, using values that match its current adapter contract; alternatively,
explicitly scope those headings to exclude Remote Agent so the documentation
remains consistent with the short compatibility matrix.
In `@adapters/remote-agent/pyproject.toml`:
- Around line 27-31: Document the functional need, considered alternatives,
narrowest-fit rationale, and license findings for httpx and nemo-relay-cli-bin
in the pull request Overview section, then run the license diff and attribution
hooks required for Python manifest changes.
- Around line 33-36: The remote-agent adapter lacks the canonical harness extra,
causing the root remote-agent extra to install the Relay CLI unnecessarily. In
adapters/remote-agent/pyproject.toml lines 33-36, add harness resolving to the
base installation; in sdk/python/nemo-fabric/pyproject.toml lines 69-71,
delegate remote-agent to nemo-fabric-adapters-remote-agent[harness] == 0.3.0
while retaining [full] only for adapter-tests.
In `@adapters/remote-agent/README.md`:
- Around line 38-40: Update the adapter README limitation statement to say it
does not expose normalized streaming, while preserving the existing note that
streamed HTTP responses are used internally.
In `@adapters/remote-agent/src/nemo_fabric_adapters/remote_agent/adapter.py`:
- Around line 73-86: Update _sse_events to flush and yield any buffered data
after response.aiter_lines() completes, preserving the current event and JSON
parsing behavior; add a test covering a stream that ends without a trailing
blank line and verifies the final completion event is processed successfully.
- Around line 315-324: Update the telemetry gate in _prepare_relay to use
common_utils.relay_enabled(payload) instead of reading
context.telemetry.relay_enabled directly, while preserving the existing None
check and return behavior.
- Line 128: Update the AsyncClient construction in the adapter initialization to
replace timeout=None with bounded connect and read timeouts, keeping the read
timeout applied per streaming chunk. Use the existing configuration pattern, and
expose the read-timeout setting through settings_schema if supported by the
adapter’s configuration.
- Around line 200-218: In stop, explicitly validate that relay is non-null
before reading relay.gateway.log_path in the RelayGatewayError handler, and
handle the absent-relay case without causing an AttributeError while preserving
the existing LifecycleError behavior and metadata when relay exists.
- Around line 116-133: Update start around the api_key_env lookup to convert a
missing environment variable into the appropriate LifecycleError, preserving the
structured startup failure. In the startup exception handler, ensure cleanup via
stop cannot replace or mask the original exception; re-raise the startup failure
after cleanup while retaining the existing behavior for successful
initialization.
In `@docs/integrations/harness/remote-agent.mdx`:
- Around line 51-52: Update the model temperature setting in both
docs/integrations/harness/remote-agent.mdx lines 51-52 and
adapters/remote-agent/README.md line 33 to use a role-qualified path, such as
models.<role>.temperature or models.default.temperature, matching the
configuration contract and test.
- Around line 5-6: Update the top-of-file SPDX header in the MDX document to use
HTML comment delimiters instead of the JSX comment wrapper, preserving the
existing copyright and license text unchanged.
- Line 61: Apply title case to the Relay gateway mode headings: update “Relay
gateway mode” to “Relay Gateway Mode” in
docs/integrations/harness/remote-agent.mdx lines 61-61 and
adapters/remote-agent/README.md lines 42-42.
In `@README.md`:
- Line 158: Correct the Remote Agent entry in the installation options table so
the full extra is not classified as installing a harness. Update the “Adapter
and Harness” column heading or add a Remote Agent-specific clarification
indicating that nemo-fabric-adapters-remote-agent[full] provides Relay gateway
support without installing a local harness.
In `@tests/adapters/test_remote_agent.py`:
- Around line 74-84: Wrap each runtime lifecycle sequence in the affected tests
with try/finally so runtime.stop() always executes after runtime.start(),
invocation, or assertions fail. Apply this to the test flow using runtime.start,
runtime.invoke, and the endpoint assertion, as well as the additional covered
sequence, while preserving the existing assertions and results.
- Line 86: Update the async tests around the request calls at lines 86, 122, and
129 to use an asynchronous HTTP client or offload the synchronous requests.get
calls to a worker thread, ensuring control-server requests and timeouts do not
block the event loop.

Before implementing, explicitly state assumptions, surface ambiguity and tradeoffs, present multiple interpretations when relevant, and ask for clarification rather than silently deciding or proceeding when requirements are unclear.

In `@adapters/claude/src/nemo_fabric_adapters/claude/adapter.py`:
- Line 48: Restore the module-level compatibility aliases for the relay settings
in adapters/claude/src/nemo_fabric_adapters/claude/adapter.py:48-48 and
adapters/codex/src/nemo_fabric_adapters/codex/adapter.py:57-57, mapping
ClaudeRelaySettings and CodexRelaySettings to the shared RelaySettings symbol so
existing imports continue to work.
In `@adapters/common/src/nemo_fabric_adapters/common/relay_gateway.py`:
- Around line 45-51: Validate RelaySettings.plugin_path before Claude startup,
rejecting None so it cannot be added to the plugin list; also guard the relay
cleanup path before calling plugin_path.exists() to avoid AttributeError. Add a
regression test covering missing plugin_path during startup and cleanup.
In `@adapters/common/src/nemo_fabric_adapters/common/utils.py`:
- Around line 20-23: Replace the ANN401-triggering Any annotations with object
or the repository’s JSON-value type alias in both normalize_user_input in
adapters/common/src/nemo_fabric_adapters/common/utils.py (lines 20-23) and
test_normalize_user_input in tests/adapters/test_adapaters_common_utils.py
(lines 26-27), preserving the existing behavior.
In `@adapters/deepagents/src/nemo_fabric_adapters/deepagents/adapter.py`:
- Around line 612-614: Update the input normalization in the Deep Agents adapter
to pass request.input directly to common_utils.normalize_user_input, preserving
None so it follows the shared adapter behavior. Add a regression test covering a
None request input and its normalized result.

for relay we may want to take a slightly different approach:
- we can't really control the relay config as the remote agent start is done outside of fabric
- fabric could provide an ATOF stream sync (invoke_stream support) if relay support has been enabled. This can be via config or via a new api to discover the remote agents capabilities.

There was a problem hiding this comment.
Could we support both terminal and native-streaming invocation modes? invoke() can continue consuming the response and returning a terminal AgentRunResult, while protocol-specific methods such as invoke_chat_completions_stream, invoke_responses_stream, and invoke_anthropic_messages_stream expose the corresponding native events and still provide a separate terminal result.
In the current implementation, Responses and Anthropic streams are consumed internally and reduced primarily to text and usage. This means the event sequence and protocol-specific content—such as tool calls, reasoning events, content-block structure, stop reasons, and other metadata—is not available to callers. Since preserving native streams is an important goal of this adapter, it would be useful to represent these protocols directly rather than map them all to the existing Chat Completions stream profile.

Overview
Add an adapter that is able to communicate with a remote agent over HTTP/HTTPS that supports one of the following APIs:
