WalkthroughAdds a mini-SWE-agent Fabric adapter with LiteLLM model support, local shell-loop execution, package and dependency integration, documentation, and unit and end-to-end tests. Changesmini-SWE-agent adapter
Estimated code review effort: 3 (Moderate) | ~25 minutes Mergeability Score: 🟡 Moderate · up to When runtime limits are omitted, the adapter can allow long-running model or shell execution, creating a concrete resource and availability risk that should be fixed or explicitly accepted before merge; it may also report zero usage cost for models with unknown pricing, requiring owner follow-up.

In `@adapters/mini-swe-agent/README.md`:
- Line 62: Make both Python examples executable by moving the module-scope await
around Fabric().run into an async main() and invoking it with
asyncio.run(main()); update adapters/mini-swe-agent/README.md line 62 and
docs/integrations/harness/mini-swe-agent.mdx line 98 consistently, or explicitly
document that they require a top-level-await-capable environment.
In `@adapters/mini-swe-agent/src/nemo_fabric_adapters/mini_swe_agent/adapter.py`:
- Around line 103-110: Update the DefaultAgent initialization to keep
system_template fixed and pass config.instructions.system.content as a separate
template variable, preventing Fabric text containing Jinja delimiters from being
rendered as instructions. Add a regression test covering system content such as
{{template}} and verify it reaches the model literally.
In `@tests/adapters/test_mini_swe_agent.py`:
- Around line 127-177: Extend the MiniSweAgentRuntime tests with focused cases
for missing workspace, missing credentials, invoking before start, and runtime
ID mismatch, asserting each contract-specific error code. Add a lifecycle
cleanup test that starts and stops the runtime, then verifies invoke fails after
stop and the runtime state is reset.
In `@tests/e2e/test_mini_swe_agent.py`:
- Around line 51-62: Update the asynchronous test’s scenario request to execute
requests.post in await asyncio.to_thread, preserving its arguments and timeout,
then call raise_for_status() on the returned response.

Learning: In the NeMo-Fabric adapters, treat path values used in Fabric adapter configuration (including logic like `_resolve_path` in adapter.py) as config-root-relative. Do not apply `Path.expanduser()` (or otherwise apply `~`/home or shell-style expansion), because it will make the resolved paths normalize inconsistently across adapters. Also, do not rely on or add any resolution behavior that uses `harness.settings.cwd` as an override point for these adapter paths—`harness.settings.cwd` is explicitly unsupported in this adapter context.

DefaultAgent.runrenderssystem_templatewithStrictUndefinedbefore the first model call. Fabric text containing{{...}}can raise or be interpreted as a template instead of reaching the model literally. Keep a fixed system template and pass the Fabric content through a template variable. This is the same unresolved issue reported in the previous review. (raw.githubusercontent.com)Source: MCP tools

The
workspace is Nonecheck does not prove that the path is an existing directory.LocalEnvironmentdeferscwduse until subprocess execution, so an invalid path becomes a command error instead of a clear lifecycle error. A relative path also depends on the adapter process directory unlessRuntimeContext.from_mappingalready resolved it.

115-127: 🗄️ Data Integrity & IntegrationRequire a runtime ID before accepting invocations.
The mismatch check only compares values. If
RuntimeContext.from_mappingreturnsNonefor a missing ID, startup storesNoneand an invocation with no ID passes becauseNone == None. Reject a missing or emptycontext.runtime_id, or verify that the contract makes this field non-optional and add a regression test.
66-72: 🗄️ Data Integrity & IntegrationEnforce lifecycle quiescence around the shared workspace.
start()can replace active state without an already-started check.invoke()runs a fresh agent in a worker thread but reuses oneLocalEnvironmentand itscwd.stop()only clears references. If lifecycle calls overlap, an old agent can modify the workspace while new state is active or after shutdown. Confirm that the common lifecycle serializesstart,invoke, andstop. Otherwise, track active work and wait for it before replacing or clearing state.Also applies to: 132-150
132-147: 🩺 Stability & AvailabilityNormalize uncaught agent failures at the adapter boundary.
DefaultAgent.runre-raises uncaught exceptions after recording them. Thisinvoke()path only buildsoutput["error"]whenrun()returns a non-Submittedstatus. Authentication, transport, and other agent failures can therefore escape without a stable adapter error code or retry policy. Verify that the common lifecycle wrapper normalizes these exceptions. Otherwise, catch the expected library errors here and return an explicit failure. (raw.githubusercontent.com)Source: MCP tools

max_turnsis optional, but this passesstep_limit=0andcost_limit=0. In mini-SWE-agent 2.4.6, both zero values disable their limits, while the native cost limit defaults to3.0. A model that does not submit can therefore continue making model calls and shell commands until the outer runtime timeout.

Timestamp: 2026-07-09T22:29:09.617Z
Learning: In the NVIDIA/NeMo-Fabric repository's Claude Agent SDK adapter (`adapters/claude-sdk/src/nemo_fabric_adapters/claude_sdk/adapter.py`), Fabric runtimes expose ordered invocations, and concurrency across invocations for a single logical runtime/session is application-owned, not adapter-owned. Concurrent invokes against one runtime/session are unsupported by design, so adapter-side locking/serialization for runtime-scoped resources (e.g., the skill plugin staging directory keyed by `runtime_id` in `_stage_skill_plugin`) is unnecessary and would violate this ownership boundary.

Timestamp: 2026-07-28T18:45:09.774Z
Learning: For the Python Hermes adapter in `adapters/hermes/src/nemo_fabric_adapters/hermes/adapter.py`, `models.temperature` is applied during `HermesRuntime.start` through the Hermes SDK `AIAgent` constructor's `request_overrides={"temperature": ...}` channel; `instructions.system` is applied at invocation time by forwarding `common_utils.system_instruction(start_payload)` as `system_message` to `AIAgent.run_conversation`. Adapter-descriptor compatibility reviews must assess both startup and invocation mappings rather than only `build_hermes_config`.

Learning: In `crates/fabric-cli/src/examples.rs`, the `code-review` example's `scripted` preset intentionally omits `FabricConfig.skills` because its deterministic adapter descriptor does not declare skill support and would fail planning. The staged `skills/code-review.md` asset is consumed only by the maintained skill-capable harness variants.

Timestamp: 2026-07-09T22:28:51.689Z
Learning: In the NeMo-Fabric adapters, treat path values used in Fabric adapter configuration (including logic like `_resolve_path` in adapter.py) as config-root-relative. Do not apply `Path.expanduser()` (or otherwise apply `~`/home or shell-style expansion), because it will make the resolved paths normalize inconsistently across adapters. Also, do not rely on or add any resolution behavior that uses `harness.settings.cwd` as an override point for these adapter paths—`harness.settings.cwd` is explicitly unsupported in this adapter context.

104-106: 🎯 Functional CorrectnessKeep Fabric system content out of the Jinja template.
At Line 106,
system.contentbecomesDefaultAgent.system_template. mini-SWE-agent renders this template withStrictUndefinedbefore the first model call. Fabric text containing{{template}}can therefore raise before execution starts. This is the same unresolved finding as the previous review. (raw.githubusercontent.com)Keep a fixed template and pass the Fabric text as a separate variable to
agent.run.Suggested fix
- template = system.content if system else DEFAULT_SYSTEM_TEMPLATE + self._system_content = system.content if system else DEFAULT_SYSTEM_TEMPLATE self._agent_kwargs = { - "system_template": template, + "system_template": "{{ fabric_system_content }}",- result = await asyncio.to_thread(agent.run, task) + result = await asyncio.to_thread( + agent.run, task, fabric_system_content=self._system_content + )

AgentModelConfig.settingscarries provider-specific settings, but this block forwards onlyapi_key,api_base, andtemperature.LitellmModelpassesmodel_kwargsto LiteLLM, so supported settings are silently ignored if the descriptor or documentation claims they are supported.

Learning: In the NeMo-Fabric adapters, treat path values used in Fabric adapter configuration (including logic like `_resolve_path` in adapter.py) as config-root-relative. Do not apply `Path.expanduser()` (or otherwise apply `~`/home or shell-style expansion), because it will make the resolved paths normalize inconsistently across adapters. Also, do not rely on or add any resolution behavior that uses `harness.settings.cwd` as an override point for these adapter paths—`harness.settings.cwd` is explicitly unsupported in this adapter context.

80-107: LGTM!Also applies to: 125-138
121-124: 🩺 Stability & AvailabilityRemove the exception-boundary concern.
The lifecycle runner converts exceptions from
invokeinto a structured failed response and marks the runtime as failed.> Likely an incorrect or invalid review comment.
140-141: 🩺 Stability & AvailabilityRemove this comment. The shared lifecycle host awaits each invocation before dispatching
stop(). EOF cleanup also runs only after the request loop exits, so this adapter cannot overlap shutdown with an active invocation through the host.> Likely an incorrect or invalid review comment.tests/adapters/test_mini_swe_agent.py (1)

Overview
nvidia.fabric.mini-swe-agentadapter, backed by the native shell-only mini-SWE-agent loop and compatible withmini-swe-agent>=2.0,<3.Dependency rationale: mini-SWE-agent is the harness being integrated. Its direct harness dependency supplies the native lifecycle and shell loop; a subprocess wrapper would not provide equivalent structured lifecycle or usage mapping. The regenerated attribution inventories record the changed direct and transitive dependency graph.
Native defaults are deliberately left unset:
wall_time_limit_seconds=0leaves invocation deadlines to Fabric'sruntime.timeout_seconds, rather than adding a second adapter-side clock;max_consecutive_format_errors=3preserves mini-SWE-agent's native loop-safety default because Fabric has no normalized equivalent; andoutput_path=Noneavoids unmanaged trajectory files because Fabric owns artifacts.Details
