Explanation
The title follows Conventional Commits format with the allowed lowercase type "feat", uses an imperative summary, stays under 72 characters, has no trailing period, and accurately describes the adapter addition.
Full details: Description check
-
Explanation
The description follows the template's required sections: Overview, Where should the reviewer start, Related Issues, and both checkboxes. It explains the adapter purpose, scope, and validation in detail. Its main gap is the Related Issues field, which says 'Relates to: none' instead of linking an issue or stating none exists. The Validation section is very long and mixes in CI status, audit failures, and review-thread history that may go stale after merge. Those details still help a reviewer, so the check passes.

Full details: Docstring Coverage
-
Explanation
Docstring coverage is 6.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 45 functions across 21 files. (1 skipped: 1 unsupported.)
Resolution
Write docstrings for the functions missing them to satisfy the coverage threshold.

Inline comments:
Review comments at @adapters/README.md:
- Line 108: Update the Strands compatibility row so the Models cell includes the
append-only system instructions detail and the Subagents cell is marked Not
exposed.
Review comments at @adapters/typescript/strands/README.md:
- Line 8: Update the product references in the Strands README prose so the first
use is “NVIDIA NeMo Fabric” and later uses are “NeMo Fabric,” including the
runtime, adapter catalog, startup, environment, and normalized server
references. Leave code identifiers such as nvidia.fabric.strands unchanged.
Review comments at @adapters/typescript/strands/test/strands-acp.test.mjs:
- Line 93: Set TEST_UNRELATED_SECRET in the parent process before calling
factory.create(input) so the state.unrelatedSecret assertion verifies the child
does not inherit it; remove the variable during test cleanup to avoid affecting
other tests.
Review comments at @docs/integrations/harness/strands.mdx:
- Line 6: Update the product reference in the Strands harness description to say
“NeMo Fabric” rather than “Fabric”; leave the SPDX header unchanged.
Review comments at @examples/code_review_agent/config.py:
- Around line 277-279: Update the HarnessConfig initialization for the Strands
adapter to set builtin_tools to read only, preventing the review agent from
receiving shell and write access by default. Update the tool lists in the
code-review agent README and Strands integration documentation to match.
Review comments at @tests/adapters/test_strands_adapter.py:
- Line 110: Update test_strands_doctor_reports_missing_binaries to accept
pytest’s monkeypatch fixture and use it to set PATH to an empty value so the
original environment is restored after the test; remove the os import only if it
is no longer used elsewhere in the file.
Review comments at @tests/scripts/test_set_typescript_project_version.py:
- Line 313: Extend the TypeScript project version test’s Strands coverage beyond
the lockfile workspace-version loop: load the Strands package manifest and
assert its version and both dependency values, then assert the corresponding
lockfile dependencies mapping. Use the expected values already established by
the test’s other adapter assertions.

## Documentation And Contribution Workflow
- Update user-facing entry points when public behavior, the `nemo-fabric` package (imported as `nemo_fabric`), examples, or supported bindings change: `README.md`, the Fern docs under `docs/` (navigation in `docs/index.yml`, site config in `fern/docs.yml`), and the adapter/integration READMEs (`adapters/README.md`, `adapters/*/README.md`, `adapters/*/*/README.md`, `sdk/python/nemo-fabric-runtime/src/nemo_fabric/integrations/*/README.md`, `examples/README.md`).
Source excerpt:
# NVIDIA NeMo Fabric Adapters
The adapter descriptor selected in `RunPlan` is authoritative for normalized
configuration, its adapter-owned settings schema, and telemetry support.

## Repository Integration
Follow these repository-specific requirements after applying the public skill:
1. Place a Python adapter under `adapters/python/<name>/` with
`LICENSE -> ../../../LICENSE`, `README.md`,
`<name>.fabric-adapter.json`, Python package and lock files, a source entry
point, and focused tests. Place TypeScript packages under
`adapters/typescript/<name>/` and wire them into that npm workspace.

There was a problem hiding this comment.
Ran this end to end with Nemotron Ultra on the B200 using Strands CLI 0.2.1. Simple invocations, warm conversation, independent runtimes, MCP on the first turn, native file reads, usage, and normal cleanup all worked as expected. The TypeScript suite, focused Python tests, and packaged-consumer checks passed. Please address the inline cleanup-retry comment before merging.

Overview
Add an AWS Strands harness adapter that reuses the shared ACP runner to launch the separately installed
strands --acp-serverCLI. NVIDIA NeMo Fabric consumers can retain a conversation across ordered invocations, select Bedrock or an explicit OpenAI-compatible Chat Completions endpoint, append system instructions, and supply MCP servers.The adapter adds no third-party production dependencies: it uses the existing NeMo Fabric contract and common packages. Reusing the native CLI avoids maintaining a separate Strands-to-ACP bridge or bundling the harness dependency graph. The Node license inventory and generated attributions are unchanged.

NVIDIA_API_KEY. Covers conversation continuation, independent runtimes, consumer usage, MCP on the first turn, and native file reads.npm test --prefix adapters/typescriptpassed earlier, including adapter suites, tarball checks, and consumer installs/lifecycle. The latest CI unit suites still pass; the current audit now fails on newly reported Zod/body-parser findings (see below).just --set no_uv true docs, strict Fern link checks, Ruff, actionlint, copyright checks, Node attributions, and Node license diff passed.just --set no_uv true test-pythonwas attempted; collection is blocked locally by missing optional Claude, Codex, mini-SWE-agent, LangGraph, and Relay dependencies. CI will run with its configured dependencies.4deb097c: 36 passed (including CodeRabbit), 3 expected skips. Checks on09b39ad7passed (36 successes, 3 expected skips). Oned86363a, both TypeScript adapter jobs passed their unit tests but failed the unchanged npm audit gate: newly reported high-severity findings affect Zod and body-parser in existing adapters. CodeRabbit completed its review ofed86363awith no new actionable comments. The full functional test matrix passed; the final macOS wheel build is queued without an assigned macos-15 runner. Current checks: 33 passed, 3 skipped, 2 npm-audit failures, 1 queued. Compatible dependency fixes and the remaining upstream SDK blockers are tracked separately in draft ci: patch dependencies and scope temporary Zod audit exception #484; this cleanup PR does not change dependency versions or audit thresholds. CodeRabbit completed its follow-up review, and all fifteen inline review threads are resolved. Earlier outside-diff release checklist and workspace inventory findings were addressed in4deb097c. Maryam’s three findings were addressed indcd3c3af; the follow-up test cleanup finding was addressed in09b39ad7. The existing autouse environment fixture covers the withdrawn PATH finding.nemo-fabric-adapters-strands@0.0.0is published and the bootstrap check passed. Authenticated trusted-publisher readback still needs confirmation before release; public package existence does not verify that configuration.ed86363a: retain invalidated sessions until cleanup succeeds, prevent replacement/invocation while cleanup is pending, and retry termination on stop. A real ACP process/descendant regression failed before the fix and passes afterward. The 17 Strands tests and 11 Python checks, including three live local E2E cases, passed.Where should the reviewer start?
