feat: add target-driven adapter discovery by AnuradhaKaruppiah · Pull Request #228 · NVIDIA/NeMo-Fabric

AnuradhaKaruppiah · 2026-08-14T05:31:34Z

Overview

Adds target-driven adapter selection and deterministic descriptor discovery.

This intentionally removes the alpha-era descriptor and workflow shapes rather than retaining compatibility aliases. The branch is rebased onto the repository’s SDK and adapter-contract package layout from #226.

Details

Splits static adapter metadata (*.fabric-adapter.json) from installed target metadata (*.fabric-target.json).
Resolves workflow.target_id first, then uses the target descriptor to select the adapter, validate workflow settings, and project the entry point into AgentConfig.
Discovers descriptors in order from bundled assets, installed package data, and explicit discovery.local_paths; identical records are deduplicated and conflicting records fail as ambiguous.
Makes harness optional for target-driven runs and sends only AgentConfig southbound.
Rejects empty discovery paths and provenance, avoids recursive symlink traversal, and preserves exact descriptor-selection assertions in tests.
Migrates the NAT, LangGraph custom-agent, and mini-SWE examples to the new descriptor shapes.
Keeps adapter-contract schemas and generated TypeScript sources under the southbound adapter-contract/ boundary introduced by refactor: organize packages by contract boundary #226.

Validation

just test-python — 1,201 passed, 17 skipped
Focused NAT, discovery, descriptor packaging, LangGraph contract, and SDK contract suite — 271 passed, 2 skipped
cargo test -p nemo-fabric-core --locked — 107 passed
just schemas
cargo fmt --all -- --check
just --set no_uv true build-python
cargo check -p fabric-python --locked
just test-typescript passes generation, generator tests, typecheck, dependency/license checks, and audit; the final package-consumer smoke test requires Node 20.18.3 or newer, while the local host has Node 18. CI runs Node 20 and 24.
just test-rust reaches the PyO3 test link step; the local host lacks libpython3.12. The Rust core suite passes locally, and CI provides the workspace link environment.

Where should the reviewer start?

Start with docs/adapter-contract/adapter-descriptor.md for the contract, then review descriptor resolution and planning in crates/fabric-core/src/config.rs.

**/*: 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.
Prefer the minimum code needed to solve the requested problem: avoid speculative features, unnecessary abstractions, unrequested flexibility, and handling of impossible scenarios; simplify overcomplicated solutions.
When editing existing code, make surgical changes only: do not modify unrelated code, comments, formatting, or pre-existing dead code; match the existing style, and remove only unused imports, variables, or functions introduced by your changes.
Define verifiable success criteria for each task, such as writing regression tests for bugs and invalid-input tests for validation, then verify the implementation against those criteria. For multi-step work, state a brief plan with a verification check for each step.

Use an NVIDIA before a noun, because the name begins with an “en” sound.
Do not add a registered trademark symbol after NVIDIA when referring to the company; use trademark symbols with product names only when required by the document type or legal guidance.
Verify official capitalization, spacing, hyphenation, and spelling for NVIDIA and third-party product names; do not rewrite official product names for grammar or title-case rules.
Precede NVIDIA product names with NVIDIA on first mention when natural and accurate, and link the first mention when the destination helps the reader.

tests/**/*.py: Use pytest to run Python tests.
Do not add @pytest.mark.asyncio to tests; async tests are automatically detected by the async runner.
Do not add -> None return type annotations to test functions.
When mocking a class, use unittest.mock.MagicMock or AsyncMock, using the spec argument when necessary, rather than defining a new class.
Prefix mocked class names with mock, not fake.
Prefer pytest fixtures over helper methods.
If a fixture is needed in multiple test files, define it once in conftest.py rather than repeating it.
Define fixtures using @pytest.fixture(name="<fixture_name>"[, scope="<scope>"]) and a <fixture_name>_fixture function; specify scope only when it is not function.
Prefer pytest.mark.parametrize over separate tests for different input types.
Use @pytest.mark.usefixtures when a fixture is needed but its returned value is unused or it returns no value.
Avoid defensive programming in tests; access expected values directly so missing data raises a clear failure, such as using results["data"] instead of results.get("data").
When adapter installation metadata changes, packaging metadata tests must directly assert that the root project depends unconditionally on the exact-version nemo-fabric-runtime distribution.
Packaging metadata tests must verify that each root harness extra delegates to the matching version of the leaf adapter's harness extra.
Packaging metadata tests must verify that bare leaf dependencies remain adapter-owned and that the root adapter-tests dependency group installs each leaf through its harness extra.
Packaging metadata tests must verify that every leaf provides full; only adapters importing NeMo Relay Python APIs provide relay, while adapters using an external Relay executable have full equal to harness.

Walkthrough

The change separates adapter descriptors from independently registered workflow target descriptors. It adds provenance-aware discovery, target-based workflow selection, optional harness configuration, target validation, runtime projection, updated schemas, SDK models, examples, and tests.

Changes

Adapter target discovery and resolution

Layer / File(s)	Summary
Configuration and descriptor contracts `crates/fabric-core/src/config.rs`, `crates/fabric-core/src/agent_config.rs`, `crates/fabric-core/src/runtime.rs`, `crates/fabric-core/src/error.rs`	Configuration now supports explicit discovery, adapter target descriptors, provenance, optional harness selection, target compatibility checks, and target-owned workflow settings schemas.
Adapter contract and discovery documentation `docs/adapter-contract/`, `adapters/README.md`, `skills/nemo-fabric-`	Documentation now describes separate adapter and target records, deterministic discovery, provenance, ambiguity errors, and target-based workflow projection.
Generated API references `docs/reference/api/python-library-reference/`, `docs/reference/api/rust-library-reference/nemo-fabric-core/`	Public API references now include discovery, target, provenance, and target-resolution types and remove obsolete descriptor fields.
SDK, examples, and schemas `python/src/nemo_fabric/`, `schemas/`, `typescript/adapter-contract/`, `external/nat/`, `examples/*`	SDK models, JSON schemas, TypeScript contracts, examples, and adapter manifests now use explicit discovery and registered workflow target IDs.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 92251

This PR changes the adapter/target configuration contract, but the current head still documents settings that can produce plans rejected during configuration and permits a retired field that may let stale settings pass unnoticed. These bounded integration risks should be corrected or explicitly accepted before merge.

Inline comments:
In `@crates/fabric-core/src/config.rs`:
- Around line 2668-2700: Deduplicate validate_adapter_target_object_schema and
validate_adapter_object_schema by extracting their shared JSON Schema validation
logic into one helper that accepts the appropriate message-to-error constructor.
Update both descriptor paths to call the helper while preserving the meta-schema
validation, object-root requirement, compile validation, and each path’s
existing error variant.
- Around line 401-424: Prevent primary() on ResolvedAdapterDescriptor and
ResolvedAdapterTargetDescriptor from panicking when deserialized provenance is
empty: either change both methods to return an Option<&DescriptorProvenance> and
update callers accordingly, or enforce non-empty provenance during
deserialization. Preserve the existing primary provenance behavior for valid
descriptors and ensure externally supplied RunPlan data cannot trigger an
expect-based panic.
- Around line 510-540: Update register_directory_tree to inspect directory
entries with symlink-aware metadata and skip symlinked directories before
recursing, while preserving traversal of regular directories and descriptor
files.

In `@docs/adapter-contract/adapter-descriptor.md`:
- Around line 37-39: Update the product naming in
docs/adapter-contract/adapter-descriptor.md lines 37-39 and 125-128, and
docs/adapter-contract/custom-agents.md lines 26-28: use “NVIDIA NeMo Fabric” on
its first occurrence and “NeMo Fabric” for subsequent occurrences, replacing
standalone capitalized “Fabric” in each affected phrase.

Apply the same fix in
`@docs/reference/api/rust-library-reference/nemo-fabric-core/config/enum-descriptorsource.mdx`
at line 4: The generated reference must reflect the corrected source
documentation comment.

In `@docs/adapter-contract/registration-and-discovery.md`:
- Around line 14-16: Update the documentation’s product references in the
sections around the adapter and target records to use “NeMo Fabric” instead of
standalone capitalized “Fabric,” while retaining bare `fabric` only for the CLI
tool; replace “may” with “can” where it expresses possibility, including the
shared-distribution and later affected statements.

In `@external/nat/README.md`:
- Around line 115-116: Update the workflow configuration guidance in the README
to remove the retired workflow.entrypoint mapping and describe
workflow.target_id selection with entry-point projection owned by the selected
target, including the local target-record discovery example. Ensure the
documented configuration matches the current planning contract and generated
schema.

In `@schemas/adapter-contract/adapter-target-descriptor.schema.json`:
- Line 1: Update the schema-generation path for
adapter-target-descriptor.schema.json to emit the required SPDX copyright and
Apache-2.0 license metadata using JSON-compatible syntax, then regenerate the
schema snapshot so the generated file begins with that header.

In `@schemas/agent.schema.json`:
- Around line 22-27: Require each local_paths item in schemas/agent.schema.json
lines 22-27 to have minLength 1 and a non-whitespace pattern, rejecting empty
and whitespace-only values. Regenerate the corresponding schema in
schemas/run-plan.schema.json lines 1085-1090, and add invalid-input coverage for
both empty and whitespace-only local_paths entries.

In `@skills/nemo-fabric-integrate/references/config-mapping.md`:
- Around line 138-142: Add a sentence to the workflow mapping guidance stating
that harness.adapter_id must match the adapter selected by the resolved target,
while harness may be omitted for target-driven runs; preserve the existing
workflow.target_id and workflow.settings rules.

In `@tests/adapters/test_external_nat_adapter.py`:
- Around line 494-495: Update the assertions in the relevant external NAT
adapter test to compare the resolved target ID exactly for each example, rather
than using startswith on plan.config.workflow.target_id. Also assert the exact
value of plan["adapter_target_descriptor"]["descriptor"]["id"], preserving the
existing harness assertion.

In `@tests/python/test_workflow_validation.py`:
- Line 75: Update the **settings parameter annotation in the affected test
helper to remove Any and satisfy ANN401, using the existing concrete
JSON-compatible type if available or object when the helper intentionally
accepts arbitrary values.

551-570: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Validate target descriptor instances.

The test checks schema keywords, but it does not validate a complete target descriptor. Add one valid workflow descriptor and invalid cases for blank id or adapter_id, an unsupported contract_version, a missing spec or entry point, and an invalid settings_schema. This will catch regressions that keyword assertions do not detect.

Encode the adapter-selector invariant in the root schema

validate_config rejects configurations with neither harness nor workflow, but schemas/agent.schema.json accepts them because its root has no selector constraint. Add a root-level constraint that requires one non-null selector, plus a regression test for the schema and planner paths.

**/*

📄 CodeRabbit inference engine (.agents/skills/karpathy-guidelines/SKILL.md)

**/*: 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.
Prefer the minimum code needed to solve the requested problem: avoid speculative features, unnecessary abstractions, unrequested flexibility, and handling of impossible scenarios; simplify overcomplicated solutions.
When editing existing code, make surgical changes only: do not modify unrelated code, comments, formatting, or pre-existing dead code; match the existing style, and remove only unused imports, variables, or functions introduced by your changes.
Define verifiable success criteria for each task, such as writing regression tests for bugs and invalid-input tests for validation, then verify the implementation against those criteria. For multi-step work, state a brief plan with a verification check for each step.

**/*: Always spell NVIDIA in all caps; do not use Nvidia, nvidia, nVidia, nVIDIA, or NV.
Use an NVIDIA before a noun, because the name begins with an “en” sound.
Do not add a registered trademark symbol after NVIDIA when referring to the company; use trademark symbols with product names only when required by the document type or legal guidance.
Verify official capitalization, spacing, hyphenation, and spelling for NVIDIA and third-party product names; do not rewrite official product names for grammar or title-case rules.
Precede NVIDIA product names with NVIDIA on first mention when natural and accurate, and link the first mention when the destination helps the reader.
On first use, include the company name and full model qualifier when it helps identify the model; preserve official capitalization and punctuation, and use shorter family names only after establishing the full name.
For learning-oriented and developer content, do not force trademark symbols unless explicitly required; for press, ...

tests/**/*.py

📄 CodeRabbit inference engine (.agents/skills/python-tests/SKILL.md)

tests/**/*.py: Use pytest to run Python tests.
Do not add @pytest.mark.asyncio to tests; async tests are automatically detected by the async runner.
Do not add -> None return type annotations to test functions.
When mocking a class, use unittest.mock.MagicMock or AsyncMock, using the spec argument when necessary, rather than defining a new class.
Prefix mocked class names with mock, not fake.
Prefer pytest fixtures over helper methods.
If a fixture is needed in multiple test files, define it once in conftest.py rather than repeating it.
Define fixtures using @pytest.fixture(name="<fixture_name>"[, scope="<scope>"]) and a <fixture_name>_fixture function; specify scope only when it is not function.
Prefer pytest.mark.parametrize over separate tests for different input types.
Use @pytest.mark.usefixtures when a fixture is needed but its returned value is unused or it returns no value.
Avoid defensive programming in tests; access expected values directly so missing data raises a clear failure, such as using results["data"] instead of results.get("data").
When adapter installation metadata changes, packaging metadata tests must directly assert that the root project depends unconditionally on the exact-version nemo-fabric-runtime distribution.
Packaging metadata tests must verify that each root harness extra delegates to the matching version of the leaf adapter's harness extra.
Packaging metadata tests must verify that bare leaf dependencies remain adapter-owned and that the root adapter-tests dependency group installs each leaf through its harness extra.
Packaging metadata tests must verify that every leaf provides full; only adapters importing NeMo Relay Python APIs provide relay, while adapters using an external Relay executable have full equal to harness.

Use after for temporal relationships instead of once, and prefer refer to over see when directing readers to another resource.
Avoid culture-specific idioms, unnecessary Latinisms, jokes, and marketing exaggeration in technical documentation.
Spell out months in body text, avoid ordinal dates, and use clear time zones.
Spell out whole numbers from zero through nine unless they are technical values, parameters, versions, or UI values; use numerals for 10 or greater and commas in thousands.
Do not add trademark symbols to learning-oriented documentation unless the source, platform, or legal guidance explicitly requires them.
Do not replace precise technical terms with simpler words when doing so would lose precision.
Do not flag passive voice when the actor is unknown or the action is the important part.

**/*.{md,rst,txt,adoc}: For technical documentation, use professional, active, conversational, engaging, precise, and plain-English prose. Prefer active voice, present tense, short sentences, and scannable paragraphs. Avoid casual or imprecise language, swearing, threats, insults, jokes, puns, culture-specific idioms, marketing exaggeration, and unsupported third-party comparisons.
Use can for possibility and reserve may for permission; use after for temporal order; use refer to for cross-references; prefer short direct sentences and specific verbs; avoid unnecessary please in technical documentation.
Prefer active voice when the actor matters. Passive voice is acceptable when the actor is unknown or irrelevant, when the action or result is the focus, or in programmer documentation.
Use natural contractions in conversational technical prose, but do not force them in formal legal copy, API references, or generated text.
Prefer simpler English over Latinisms: use for example or such as instead of e.g., and so on instead of etc., that is instead of i.e., compared to instead of vs., and by, through, or using instead of via. Use industry-standard terms such as in silico, in vitro, and in vivo when appropriate, and italicize them in running text.
Use that without commas for essential clauses, and which with commas for nonessential clauses.
Format dates and times clearly: spell out months in body text; use forms such as June 12, 2025; avoid numeric or ordinal dates; capitalize days; use 12-hour time when appropriate; include a space before a.m. or p.m.; use ET and PT for needed time zones; avoid 24/7; and prefer from 12:30 to 1:00 p.m. for prose ranges.
Format numbers consistently: spell out zero through nine in body text, use numerals for 10 or greater and for technical values, use commas in thousands, do not begin a sentence with a numeral, spell out ordinals, and use numerals consistently within a category wh...

The workflow.entrypoint YAML examples now read as consumer configuration, which no longer accepts entrypoint.

FabricConfig.workflow accepts target_id and settings only. The entry point lives in the Adapter Target Descriptor under spec.entrypoint, and NeMo Fabric projects it into AgentConfig.workflow.entrypoint. The snippets at lines 58-63, 80-85, and the python_module example show a bare workflow.entrypoint block with no owner stated, so a reader can copy it into an agent config and fail planning.

State that each snippet is the target descriptor spec fragment, or show the full *.fabric-target.json shape used in docs/adapter-contract/adapter-descriptor.md.

As per path instructions, "Treat incorrect or stale commands, package names, paths, APIs, support claims, procedures, examples, terminology, or public behavior documentation as blocking issues."

**The stop error disappears when the invocation already failed.**

The `Err(_) => {}` arm discards the stop failure whenever `result.status != RunStatus::Succeeded`. The invocation error is correctly preserved, but the host teardown failure leaves no trace in `result.events`, `result.error`, or logs. Operators lose the signal that a runtime failed to stop.

Record the stop failure without overwriting the primary error, for example as an event or in `result.error.metadata`.

tests/**/*.py

📄 CodeRabbit inference engine (.agents/skills/python-tests/SKILL.md)

tests/**/*.py: Use pytest to run Python tests.
Do not add @pytest.mark.asyncio to tests; async tests are automatically detected by the async runner.
Do not add -> None return type annotations to test functions.
When mocking a class, use unittest.mock.MagicMock or AsyncMock, using the spec argument when necessary, rather than defining a new class.
Prefix mocked class names with mock, not fake.
Prefer pytest fixtures over helper methods.
If a fixture is needed in multiple test files, define it once in conftest.py rather than repeating it.
Define fixtures using @pytest.fixture(name="<fixture_name>"[, scope="<scope>"]) and a <fixture_name>_fixture function; specify scope only when it is not function.
Prefer pytest.mark.parametrize over separate tests for different input types.
Use @pytest.mark.usefixtures when a fixture is needed but its returned value is unused or it returns no value.
Avoid defensive programming in tests; access expected values directly so missing data raises a clear failure, such as using results["data"] instead of results.get("data").
When adapter installation metadata changes, packaging metadata tests must directly assert that the root project depends unconditionally on the exact-version nemo-fabric-runtime distribution.
Packaging metadata tests must verify that each root harness extra delegates to the matching version of the leaf adapter's harness extra.
Packaging metadata tests must verify that bare leaf dependencies remain adapter-owned and that the root adapter-tests dependency group installs each leaf through its harness extra.
Packaging metadata tests must verify that every leaf provides full; only adapters importing NeMo Relay Python APIs provide relay, while adapters using an external Relay executable have full equal to harness.

Spell out whole numbers from zero through nine unless they are technical values, parameters, versions, or UI values; use numerals for 10 or greater and commas in thousands.
Do not add trademark symbols to learning-oriented documentation unless the source, platform, or legal guidance explicitly requires them.

Use can for possibility and reserve may for permission; use after for temporal order; use refer to for cross-references; prefer short direct sentences and specific verbs; avoid unnecessary please in technical documentation.
Prefer active voice when the actor matters. Passive voice is acceptable when the actor is unknown or irrelevant, when the action or result is the focus, or in programmer documentation.
Use natural contractions in conversational technical prose, but do not force them in formal legal copy, API references, or generated text.
Prefer simpler English over Latinisms: use for example or such as instead of e.g., and so on instead of etc., that is instead of i.e., compared to instead of vs., and by, through, or using instead of via. Use industry-standard terms such as in silico, in vitro, and in vivo when appropriate, and italicize them in running text.

Learning: In NVIDIA NeMo Fabric Python SDK serialization of `RuntimeCapabilities` (to satisfy the “parity contract” with Rust core and the CLI), do not emit metadata keys when the corresponding metadata is absent. Instead, omit those fields entirely so the produced JSON matches the Rust/CLI output (e.g., avoid `null`, empty objects, or placeholder metadata). During review, verify the serializer/builders follow this omission rule and that Python outputs/parity tests reflect the same shape.

Looks good to me, one minor comment, and one out of diff update:

contribute-adapter Skill still mandates literal fabric-adapter.json; nemo-fabric-integrate (line 299) still says workflow validation comes from the adapter descriptor instead of the target descriptor.

Update the third-party adapter evaluation for the target-driven discovery contract merged in PR #228. Require named adapter descriptors, registered target descriptors, aligned contract versions, target settings validation, and discovery of both descriptor types. Validation: both skill quick validations; eval JSON shape checks; just --fmt --check; git diff --check; targeted pre-commit hooks Signed-off-by: Allan Enemark <exactly.allan@gmail.com>

#### Overview - Publish the repository adapter-contract documentation as the maintained, incremental guide for harness adapters and custom-agent integrations. - Normalize the southbound lifecycle around `AgentConfig`, `AgentRunRequest`, `RuntimeContext`, and `AgentRunResult`. - Migrate all five bundled adapters, the NVIDIA NeMo Agent Toolkit adapter, and the LangGraph custom-agent example to the typed request and result boundary. - Keep request projection and consumer-facing result enrichment in the NeMo Fabric core, and remove the redundant descriptor input selector. - Regenerate the JSON Schemas, Python and TypeScript bindings, and Rust API reference; update the public authoring skill, release notes, examples, and repository overview. Adapters now receive `AgentConfig` at startup, receive `AgentRunRequest` and `RuntimeContext` for each invocation, and return one typed `AgentRunResult`. Adapter authors can follow the staged guide and use Hermes Agent as the complete harness reference, mini-SWE-agent as the minimum-surface example, NVIDIA NeMo Agent Toolkit as the shared-framework example, or the LangGraph email-phishing analyzer as the dedicated custom-agent example. #### Where Should the Reviewer Start? Start with `docs/adapter-contract/README.md` for the reader path and minimum surface, then review `docs/adapter-contract/execution.md` and `crates/fabric-core/src/agent_execution.rs` for the typed lifecycle boundary. #### Validation - Full Python and Rust workspace suites passed. - TypeScript generation, generated-file, type, dependency, audit, and package checks passed. - Documentation copyright, API reference, strict link, and Mermaid render checks passed. - Final review fixes: 131 focused adapter tests and the artifact-collision Rust regression test passed. Relates to #228 Closes FABRIC-211 Closes FABRIC-212 - [x] I confirm this contribution is my own work, or I have the right to submit it under this project's license. - [x] I searched existing issues and open pull requests, and this does not duplicate existing work. ## Summary by CodeRabbit * **New Features** * Added configurable Adapter Targets for harnesses, shared frameworks, and custom agents. * Standardized invocation results with statuses, structured errors, artifacts, token usage, and cost details. * Added optional native OpenAI streaming and adapter extension validation. * Added normalized usage details to SDK run results. * Expanded custom-agent, MCP, LangGraph, and mini-SWE-agent integration support. * **Documentation** * Updated Fabric 0.2 and v1alpha2 adapter contract guidance. * Added examples, discovery guidance, streaming instructions, and adapter verification checklists. * Clarified configuration and lifecycle requirements for adapter integrations.

Update the third-party adapter evaluation for the target-driven discovery contract merged in PR #228. Require named adapter descriptors, registered target descriptors, aligned contract versions, target settings validation, and discovery of both descriptor types. Validation: both skill quick validations; eval JSON shape checks; just --fmt --check; git diff --check; targeted pre-commit hooks Signed-off-by: Allan Enemark <exactly.allan@gmail.com>

#### Overview Adds direct NVSkills evaluation coverage for both public NVIDIA NeMo Fabric integration skills. This lets PR #232 exercise the full per-skill scan, live eval, benchmark, and signature path rather than only the repository-level dispatch/status plumbing. The existing release-collection note remains as the marker for collecting merged skill updates before the next external skills-registry publication. #### Details - Add a native OpenAI versus NeMo Relay streaming-boundary eval to `nemo-fabric-integrate`. - Add positive adapter-authoring and native-streaming evals to `nemo-fabric-build-adapter`. - Cover the target-driven discovery contract merged in #228: named adapter descriptors, registered target descriptors, aligned contract versions, target settings validation, and discovery of both descriptor types. - Keep the native-streaming eval scoped to adapter-owned chunk mapping, terminal outcomes, failure translation, and exactly-once target invocation; the common host owns NDJSON framing and consumer lifecycle. - Add negative routing evals so consumer SDK integration and first-party repository maintenance do not invoke the portable adapter skill. - Confirm both skill packages match the canonical skill format. - Keep `skills/nemo-fabric-build-adapter/agents/openai.yaml` unchanged. It is valid optional Codex UI metadata; `evals/evals.json` is the artifact required for NVSkills Tier 3 evaluation. Release-queue dependency status: - No other Fabric PR is currently open. - #228, #234, and #236 are merged. Their public skill changes are incorporated through the upstream `main` merges on this branch. - #238 is merged after the current branch head but changes only maintainer skills and documentation, not either public integration skill. The NVSkills signer confirmed that `main` moved without changing the validated public skill folders. #### Validation Local validation: - `.venv/bin/python /Users/aenemark/.codex/skills/.system/skill-creator/scripts/quick_validate.py skills/nemo-fabric-integrate` - `.venv/bin/python /Users/aenemark/.codex/skills/.system/skill-creator/scripts/quick_validate.py skills/nemo-fabric-build-adapter` - `jq` required-field assertions for both `evals/evals.json` files - `just --fmt --check` - `git diff --check` - Targeted pre-commit hooks for both skill packages Final NVSkills content run: - Central run: https://github.com/NVIDIA/nvskills-ci/actions/runs/31853483588 - Downstream pipeline: https://gitlab-master.nvidia.com/nvcarps/ci-group/nvcarps-ci/-/pipelines/62797284 - Tier 1: passed - Tier 2: passed - SkillCritic: passed with advisory findings only - Tier 3: passed - Content gate: passed - Report publication: passed - `nemo-fabric-build-adapter`: with-skill `0.87`, baseline `0.60`, lift `+0.27` - `nemo-fabric-integrate`: with-skill `0.83`, baseline `0.59`, lift `+0.24` Signature publication blocker: - 3S signed and verified both skill packages. - The service generated commit `feb1cda` with both `BENCHMARK.md`, `skill-card.md`, and `skill.oms.sig` files. - GitHub rejected all three bot push attempts because the Fabric `All Branches` ruleset requires DCO and has no bypass actor for the `nv-skills-ci` GitHub App. - The app integration `3871061` must be added as a ruleset bypass actor, or the service must provide another supported signature-commit push strategy. No product code, public API, dependency, or breaking change is included. #### Where should the reviewer start? Start with `skills/nemo-fabric-build-adapter/evals/evals.json`, then review the added streaming-boundary case in `skills/nemo-fabric-integrate/evals/evals.json`. #### Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to) - Relates to: [FABRIC-209](https://linear.app/nvidia/issue/FABRIC-209/validate-fabric-nvskills-ci-and-collect-v02-skill-updates) - [x] I confirm this contribution is my own work, or I have the right to submit it under this project's license. - [x] I searched existing issues and open pull requests, and this does not duplicate existing work. ## Summary by CodeRabbit - **New Features** - Added guidance for collecting public integration-skill updates before release publication while retaining source references. - Added skills for building NVIDIA NeMo Fabric adapters and integrating with the NeMo Fabric typed Python SDK. - Added usage guidance, security considerations, evaluation details, and benchmark results for both skills. - **Tests** - Added evaluation scenarios covering adapter authoring, streaming behavior, integration boundaries, and error handling. - **Documentation** - Added benchmark reports and signed provenance metadata for both skills.
