📝 Walkthrough

Walkthrough

Optimization now supports self-contained fileset bundles for remote submission. It validates bundle contents, stages configuration and datasets, selects execution profiles, publishes results, and adds the prepare-fileset CLI workflow with updated schemas, examples, tests, and documentation.

Changes

Fileset-backed optimization submission

Layer / File(s) Summary
Configuration contract and bundle validation
plugins/nemo-agents/openapi/openapi.yaml, plugins/nemo-optimization/src/nemo_optimization/schemas/optimize.py, plugins/nemo-optimization/src/nemo_optimization/bundle.py, plugins/nemo-optimization/tests/test_bundle.py
OptimizeSpec documents configuration filesets and output targets. Bundle preflight validates YAML, agents, optimizers, paths, datasets, hooks, required assets, and symlinks.
Bundle staging CLI
plugins/nemo-agents/src/nemo_agents_plugin/cli.py, plugins/nemo-agents/src/nemo_agents_plugin/jobs/optimize_cli.py, plugins/nemo-agents/tests/unit/test_optimize_prepare_fileset_cli.py
optimize prepare-fileset validates bundles, optionally preflights models, supports dry runs, uploads bundles, and prints a matching submit command.
Profile selection and staged execution
plugins/nemo-optimization/src/nemo_optimization/jobs/optimize.py, plugins/nemo-optimization/tests/test_optimize_job.py
Submissions require a configuration fileset. Runtime stages filesets, resolves bundle-relative paths, stages datasets, selects subprocess or CPU profiles, restores the working directory, and publishes results.
Result publication and workflow support
docs/agents/optimization.mdx, plugins/nemo-optimization/README.md, plugins/nemo-optimization/examples/hermes-optimize/*, pyproject.toml
Documentation and examples describe bundle-relative local runs, fileset submission, output publication, execution profiles, and the CPU task dependency.

Replace the string return annotation with typing.Self.

The coding guidelines require concrete type hints over string-based ones. Self works inside the class body, where the class name is not yet bound.

guidance to use the CLI’s registered list-execution-profiles command instead of
execution-profiles; leave the surrounding explanation unchanged.

In `@plugins/nemo-optimization/README.md`:
- Around line 9-17: Update the README to place installation and platform-access
prerequisites before the command documentation, then append a “Next Steps”
section linking to the bundle example and submission workflow. Keep the existing

- Around line 136-153: Update _path_problems and the bundle preflight to reject
every symlink beneath source before upload, including unreferenced files and the
configuration path. Use non-following symlink checks so referenced targets
cannot escape source, and preserve the existing file/directory validation for
regular paths.
- Around line 136-146: Update _path_problems to validate each reference with
is_fileset_relative before applying the environment-variable exception, so
absolute dynamic paths such as /tmp/${DATASET} are reported while relative
${DATASET} remains valid.

In `@plugins/nemo-optimization/src/nemo_optimization/schemas/optimize.py`:
- Around line 18-22: Update the optimize_config field in the optimization schema
to reject empty strings while preserving valid absolute and fileset-relative
paths. Add the smallest validation constraint or validator at the field/schema
level so optimize_config="" cannot pass validation or reach fileset staging.

- Around line 85-86: Update the Hermes setup instructions in the README to use a
separate uv-managed project or lock for installing the pinned
hermes-agent==0.18.2, keeping it out of the shared workspace lock and preserving
the requests constraint; remove the manual uv pip install --no-deps workaround
and ensure the documented flow reliably provides hermes_cli after uv sync.

In `@plugins/nemo-optimization/src/nemo_optimization/schemas/optimize.py`:
- Around line 75-78: Update is_fileset_relative() to reject paths with a
non-empty Windows drive, including drive-relative forms such as D:optimize.yml,
before accepting the path as relative. Preserve existing tilde, absolute-path,
and parent-traversal checks, and add a regression test covering this Windows
drive-relative case.
- Around line 35-38: Update OptimizeSpec.agent in optimize.py to reject empty
strings while allowing None, and update _agent_problems in bundle.py to treat ""
as absent when validating the required Agent under Test. Apply the change at
both affected sites, preserving existing handling for valid agent references and
inline Fabric agent packages.
