WalkthroughThe change adds explicit ChangesSystem instruction contracts and planning
Adapter runtime resolution
Example and external adapter composition
Documentation and integration guidance
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to This PR makes system-instruction composition explicit: omitted mode uses replace, append is accepted only by capable adapters, and unsupported modes fail closed. Existing NeMo Agent Toolkit configurations relying on implicit additive behavior need explicit append; remaining merge-readiness risk is bounded to a missing no-op assertion and inaccurate or poorly formatted documentation that could permit a regression or confuse maintainers.

normalized-configuration.md to end each complete sentence with a period.
In `@docs/integrations/harness/mini-swe-agent.mdx`:
- Line 55: Update the documentation text describing the adapter’s supported
configuration to identify `instructions.system` with `replace` mode, replacing
the invalid `replacement` mode name while preserving the references to
`runtime.max_turns`.
In `@sdk/python/nemo-fabric-runtime/src/nemo_fabric/types.py`:
- Around line 313-314: Update _InstructionConfig.from_mapping to validate that
mode is a string before performing the {"replace", "append"} membership check,
raising FabricConfigError for all invalid values including unhashable inputs
such as lists and dictionaries. Add a mapping-path test covering non-string
modes.

#### Overview Add NVSkills evaluation coverage for consumer-skill guidance that changed after the last signed benchmark baseline. This keeps the PR limited to evaluation inputs; NVSkills CI will regenerate and sign the derived skill artifacts. - [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. #### Details - Cover `instructions.system.mode` omission, `replace`, `append`, descriptor claims, planning validation, and adapter startup validation in the adapter-authoring skill. - Cover typed consumer mapping and compatibility planning for `replace` and `append` in the SDK integration skill. - Cover UUID and non-UUID Relay request correlation at the adapter-owned invocation scope boundary. #### Validation - `jq empty skills/nemo-fabric-build-adapter/evals/evals.json skills/nemo-fabric-integrate/evals/evals.json` - `just --fmt --check` - `pre-commit run --files skills/nemo-fabric-build-adapter/evals/evals.json skills/nemo-fabric-integrate/evals/evals.json` - `git diff --check` - [Ordinary GitHub CI](https://github.com/NVIDIA/NeMo-Fabric/actions/runs/33677831745): passed across Python tests and wheel builds; TypeScript, Rust, pre-commit, DCO, and CodeRabbit also passed - [NVSkills CI](https://github.com/NVIDIA/nvskills-ci/actions/runs/33677880562): downstream benchmark run in progress No product code or dependency manifests changed. #### Where should the reviewer start? Start with `skills/nemo-fabric-build-adapter/evals/evals.json`; its two new cases cover both public behaviors added since the previous NVSkills run. Then review the consumer-side instruction-composition case in `skills/nemo-fabric-integrate/evals/evals.json`. #### Related Issues: (use one of the action keywords Closes / Fixes / Resolves / Relates to) - Relates to #262 and #263 ## Summary by CodeRabbit * **New Features** * Expanded evaluation coverage for adapter construction and runtime integration, including system-instruction modes, validation, request correlation, metadata handling, and cleanup behavior. * **Documentation** * Updated skill descriptions, reference labels, evaluation metrics, version details, and benchmark results. * Refreshed benchmark records with six-task evaluation coverage and updated execution metadata for both skills. * **Tests** * Added evaluation scenarios covering replace/append instruction policies, unsupported modes, planning validation, request ID formats, and invocation boundaries.

Overview
Add explicit
replaceandappendcomposition modes for normalized system instructions.replaceremains the portable default. Adapter descriptors declare exact support when they opt into mode discovery; legacy descriptors that omit the declaration remain replace-only.Details
appendonly through adapters with a stable harness-native seam.Compatibility note: NeMo Agent Toolkit configurations that set
instructions.systemmust now specifymode="append". Earlier adapter versions accepted an omitted mode but always mapped the value to additiveadditional_instructions, contradicting the portablereplacedefault. The adapter cannot truthfully implement replace, so this PR makes the additive mode explicit and rejects the unsupported default.Validation
