PyYAML 6.0.3 yaml.YAMLError class inheritance ValueError safe_load malformed YAML
💡 Result:
In PyYAML, all library-specific exceptions inherit from yaml.YAMLError, which is a direct subclass of the built-in Exception class [1][2]. The exception hierarchy is designed so that specific error types, such as MarkedYAMLError (which provides contextual information like line and column numbers), inherit from YAMLError [1][2]. Most other specific error types, including ConstructorError, ScannerError, and ParserError, are subclasses of MarkedYAMLError [2][3]. Regarding recent issues with safe_load and malformed YAML: historically, certain malformed inputs (such as numeric scalars like 0x_ or explicitly tagged types like!!bool "maybe") could cause the library to raise raw built-in exceptions like ValueError, KeyError, or IndexError instead of the expected yaml.ConstructorError [4][5][6]. This was problematic for applications that rely on catching yaml.YAMLError to handle parsing failures gracefully [4]. Recent updates, including those reflected in the PyYAML 6.0.3 development cycle, have introduced fixes to wrap these raw exceptions within ConstructorError [5][7][8]. These changes ensure that when the loader encounters malformed YAML, it raises a proper library-specific exception that inherits from YAMLError, maintaining expected error-handling patterns [7][8].

Catch yaml.YAMLError in _candidate. When PyYAML is available, malformed YAML raises yaml.YAMLError, which is not a ValueError. The current handler lets the exception abort scan_repository; keep the handler safe when yaml is None.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
_close_logger_handlers failure reports a false resolution failure.
Job.create resolves the job. job._close_logger_handlers() is cleanup on a private API. Both sit inside the same try, so an AttributeError from a Harbor rename reports "Harbor could not resolve the job" although resolution succeeded. _resolved_task_paths already guards the private _task_configs with getattr; apply the same care here.
Proposed fix
try:
with tempfile.TemporaryDirectory(prefix="eval-author-jobs-") as scratch:
job = await Job.create(config.model_copy(update={"jobs_dir": Path(scratch)}))

Customers are wary of deploying an agent into their codebase to act on
their code, so package Eval Author's discovery pass as a skill their own
agent can run instead.
Two skills, following a core-plus-sub-flow shape:
- eval-author: the standard that governs every sub-flow, which is that a
provider's own validators judge each recorded fact rather than the agent
inferring it from file layout. Also owns the shared vocabulary, the
boundaries, and the routing.
- eval-author-discover: the discovery sub-flow. Probes for Harbor,
inventories the repository with the standard library, then runs Harbor's
full validation ladder in-process when Harbor is importable, and reports
an unproven inventory when it is not.
The skill ships no dependency of its own. Harbor is its only import beyond
the standard library, and a repository holding Harbor evaluations has
Harbor by construction; PyYAML, pydantic, and toml arrive with it.
Provider code sits under scripts/providers/harbor/ rather than
scripts/harbor/: a directory named harbor on sys.path satisfies
find_spec("harbor") on a machine without Harbor, which would make the
probe claim an install that is not there.

…ills Harbor tasks live in the customer's repository, so a CLI that proposes changes has to write to that repository, and customers would not grant that however it was sandboxed. The skills are the replacement: the customer's own agent does the work and nothing gets installed. Removes the nemo agents eval-author command group, its entry point, and the discovery/ package behind discover, along with their tests. The eval-author-discover skill covers the same ground: it probes for an installed Harbor, finds the repository's configs and tasks with the standard library, then has Harbor's own validators judge each one. Dependencies drop to pyyaml and nemo-insights-plugin, both for the contract test, because the bundled scripts import the standard library only. The package still resolves as a namespace package, so root test discovery keeps finding its tests, and nemo agents now lists only analyst and experimentalist. Vendor left the entry point behind pointing at the deleted module, so that line comes out by hand; vendor then reclaims the table and stops rewriting it.

The comment justified bundling Eval Author with Experimentalist and Insights by a dependency cycle that no longer exists: Experimentalist no longer imports EvalAuthor, and Eval Author no longer borrows Experimentalist helpers. Only the shared Insights profile contract remains, and that alone would not require co-bundling. Records why the entry stays anyway, which is that bundling is how the skills reach a customer through nemo-platform[all], and notes that the entry-point inherit is now a no-op so nobody reads the empty clause as a bug.

Move test-only dependencies out of the runtime dependency list.
The comment says nemo-insights-plugin and pyyaml only support tests/test_skill_contract.py, but Lines [13-14] keep them in the project dependencies. A normal install therefore pulls the platform plugin for a skills-only package. Move these entries to a test or development dependency group and install that group with uv.

Narrow the standalone-runtime claim.
“Standard library only” and “whatever Python the customer already has” overstate the contract. eval-author-discover can use optional Harbor, as documented by plugins/nemo-eval-author/tests/test_skill_contract.py, Lines [4-30]. The package metadata supports only Python 3.12 and 3.13 at plugins/nemo-eval-author/pyproject.toml, Line [8]. State that copied scripts have no mandatory third-party dependency on supported Python versions and may use Harbor when available.

uv run --python existing virtual environment interpreter script official documentation
💡 Result:
The uv tool is designed to manage Python environments and execute commands within them. When using uv run, uv typically attempts to discover and use a project-specific or local virtual environment [1][2][3]. To force or specify a particular Python interpreter or existing virtual environment when running a command, you can use the --python flag [4][5]. How to use the --python flag: 1. Specifying an interpreter or environment path: The --python option accepts a path to a specific Python interpreter executable (e.g., /path/to/bin/python) or the root directory of an existing virtual environment [6][5]. Example: uv run --python /path/to/venv my_script.py 2. Behavior with discovered environments: If the interpreter request (e.g., --python 3.12) is satisfied by an already discovered environment, uv will use that environment [4]. If you provide a path that is not a virtual environment, uv may still use it, though depending on the context, you might need the --system flag if you intend to modify a non-virtualized system Python environment [6]. 3. Important Considerations: - Command Separation: If you are running a command that accepts its own flags or arguments, you can use -- to cleanly separate uv's options from the command [4]. Example: uv run --python 3.12 -- python -c "print('hello')" - Environment Discovery: By default, uv run searches for a virtual environment in the current directory or parent directories (typically named .venv) [1][3]. If an environment is found, it is generally used for the command execution [1][4]. - Version Requests: The --python flag also accepts version strings (e.g., 3.12, cp312), which instructs uv to find a compatible Python interpreter (downloading it if necessary) [2][5]. If you find that uv run is unexpectedly ignoring an active virtual environment or recreating one, ensure that no environment variables (like UV_PYTHON) are overriding your preferences, as these can influence interpreter selection [7].

Return an unproven inventory when Harbor is unavailable.
“Report that and stop” conflicts with eval-author-discover/SKILL.md Lines [39-53] and test_skill_contract.py Lines [400-419]. Discovery must still return the inventory, set proven and runnable to false, suppress run_command, and mark findings unproven. Stop provider validation and installation, not report generation.
This matches the downstream discovery contract and its contract test.

The package has no entry points and no importable code, so bundling it into the platform distribution shipped files that nothing can discover. `nemo skills list` reads the `nemo.skills` registry and these skills are not registered there yet, so a customer installing nemo-platform[all] received two SKILL.md files reachable only by knowing a path inside the wheel. Installing them into service images through enabled-plugins had the same problem. Removes the [tool.bundle-package] entry, which is what generated the nemo-eval-author-plugin extra along with its membership in the plugins and all extras, and drops the package from enabled-plugins. Regenerating cleared every eval-author reference out of the published wrapper. The package stays a uv workspace member, so uv sync --all-packages still installs it for development and the contract test still runs. Bundle it again when the skills register under nemo.skills and a distribution has something to expose. Signed-off-by: Alec Khoury <akhoury@nvidia.com>
The CLI uploaded a discovery.md to a fileset, which the skills cannot do and should not: they talk to no platform service. Without a replacement, findings died with the run that produced them and the next reader had to redo discovery using the Harbor install the report exists to describe. The skill now tells the agent to save the report to .eval-author/discovery.md, leading with the JSON as front matter so a later model reads the verdict, the run command, and the required host variables from the file alone. The report stays visible and uncommitted: it is worth committing so a teammate skips the discovery pass, but that is the user's call, and the repository's .gitignore is not ours to edit. Saving is guidance rather than plumbing. The scripts write no files at all, so deciding where a file belongs in someone's repository stays a judgement made in the open. That let discover.py drop --out and its Markdown renderer, and the sub-flow trade its blanket no-writes grant for Write without Edit: create your own report, never rewrite anything that predates you.

Compare file contents, not only file names.
The snapshot at Line 442 cannot detect changes to an existing file. Capture file contents before and after discover.py, then compare both mappings.

Summary
Harbor tasks live in the customer's repository, so a tool that proposes changes to an eval suite has to write to that repository, and customers would not grant that however it was sandboxed. This replaces the
nemo agents eval-authorCLI with skills the customer's own coding agent reads and follows, so the work happens under their agent's existing permissions and nothing gets installed. Before, establishing whether a repository's Harbor evaluations run requirednemo agents eval-author discover, which needs the platform installed and a workspace resolved; now a copyable skill directory does it against a local checkout.This is a breaking change. The
nemo agents eval-authorcommand group is gone, along with its four placeholder verbs.nemo agentsnow lists onlyanalystandexperimentalist.Changes
Added
Two skills under
plugins/nemo-eval-author/src/nemo_eval_author_plugin/skills/, in a core-plus-sub-flow shape:eval-author(core): owns the standard that governs every sub-flow — a provider's own validators judge each recorded fact, rather than the agent inferring it from file layout. Also owns the shared vocabulary (check, required, advisory, rung, proven, provider), the boundaries, and the routing table. Granted[Read, Grep, Glob]only, because it routes and explains rather than executing.eval-author-discover(sub-flow): the discovery steps, deferring the standard to the core rather than restating it. Runs three phases in one invocation: probe for Harbor, inventory the repository with the standard library, then run Harbor's eight-rung validation ladder in-process when Harbor is importable. Ends by saving a report to.eval-author/discovery.md, so findings outlive the run.Bundled scripts (
eval-author-discover/scripts/):discover.py— entry point. Owns phase order, report assembly, and the exit code; nothing provider-specific. Prints JSON and writes no files._checks.py— the check-result contract, a standard-library port ofnemo_insights_plugin.contracts.checksso a skill report reads the same as a platform one.providers/harbor/_probe.py— Harbor capability detection viafind_spec, so a missing Harbor costs no import.providers/harbor/_inventory.py— finds job configs, datasets, and task directories. Standard library only.providers/harbor/_ladder.py— runs Harbor's validators. Imported only after the probe reports Harbor available.Removed
The CLI is removed in full, not deprecated, because the skill supersedes it and a command group whose only working verb is replaced has nothing left to offer:
cli.pyand thenemo.cli.agentsentry point, including theaudit,propose,run, anddoctorverbs, which were placeholders that exited nonzero.discovery/package (run.py,scan.py,validate.py,report.py) that implementeddiscover.tests/discover/(4 files),test_cli.py,harbor_fixtures.py, andconftest.py, which existed to configurelitellmfor the agent tests that moved to Experimentalist in refactor(eval-author): move the Eval Author agent into Experimentalist #1413..env.example, which documented model variables for that same agent.The package is now two
SKILL.mdfiles, their scripts, and one contract test. Dependencies drop from seven to two:pyyamlandnemo-insights-plugin, both only for the contract test, because the bundled scripts import the standard library alone. Droppingharbordoes not change the dependency closure, since Experimentalist and the evaluator SDK also declare it.Design decisions worth a reviewer's attention
discovery.mdto a fileset, which these skills cannot do and should not: they talk to no platform service. Rather than move that plumbing into the script, the skill states where the report goes (.eval-author/discovery.md, leading with the JSON as front matter) and lets the agent write it. Where a file belongs in someone's repository is a judgement, so it stays in the open where the user can see it. The report is left visible and uncommitted — worth committing so a teammate skips the discovery pass, but that is the user's call, and their.gitignoreis not ours to edit.WritewithoutEdit. It creates its own report and never rewrites a file that predates it, which is the permission customers actually declined. The core stays read-only, since it only routes. A test enforces both halves.harbor job start --print-configexits 0 on a config naming a nonexistent dataset path and a nonexistent agent, so only 2 of the 8 rungs are reachable from the CLI. The ladder therefore runs in-process, where the same config producesresolutionandagentfailures."proven": false, the rendered output labels those lines(observed, not proven), and the exit code is 1.scripts/providers/harbor/, notscripts/harbor/. A directory namedharboronsys.pathis importable as a namespace package, which makesfind_spec("harbor")succeed on a machine with no Harbor and the probe claim an install that is not there. A test guards this.make vendorleft theeval-authorentry point inpackages/nemo_platform/pyproject.tomlpointing at the deletedclimodule, and dropped that table's "Generated" marker comment.nemo agentsskips entry points that fail to import, so this would have shipped as invisible dead metadata rather than a visible break. Removing the line lets vendor reclaim the table, restore the marker, and stop rewriting it; I confirmed vendor does not re-add it.Tests:
plugins/nemo-eval-author/tests/test_skill_contract.py, 24 cases covering frontmatter completeness againstdocs/contributing/skills-spec.mdx, the core/sub-flow routing contract, the dependency boundary (an AST walk that fails on any import outside the standard library, a sibling, or Harbor's own dependencies), the lazy-ladder-import guarantee, the provider name-collision guard, contract parity with the platform'schecks.py, and discovery behavior on valid, broken, and Harbor-free repositories.Type of Change
Quality Gates
Documentation touched, because removing a command group makes four passages wrong:
docs/agents/insight-driven-optimization.mdxdescribed thenemo agents eval-authornamespace, listed it in a setup verification snippet, named it in the command reference intro, and gave it its own reference section. The plugin README is rewritten around the skills, and the Experimentalist plugin's README,AGENTS.md, andeval_author/README.mdno longer point at a CLI that exists.Verification

uv run --frozen nemo agents --helplists onlyanalystandexperimentalist. The eval-author group is gone from the CLI surface.find_spec("nemo_eval_author_plugin")still resolves, as a namespace package, even though the package now holds no Python modules. This matters becausetests/discovery_exclusions.pyskips the plugin's tests when that lookup returnsNone, so a wrong answer here would have silently dropped the contract test from root test discovery rather than failing.make vendoris idempotent: a second run leaves the tree clean, which is the conditionlint-sdk-vendoredchecks.uv.lockdiff is 27 deletions with no change to anyname,version, orsourceline, so no package resolution moved.Behavioral verification of the skill itself, run against a scratch repository holding one valid Harbor task and one job config:
proven: true,runnable: true, all eight rungs pass, and the report returnscd <repo> && harbor job start -c harbor-job.yaml.python -S, which drops site-packages): exit 1,proven: false,harbor_importable: false, and every finding other than theharborcheck itself marked unproven.scripts/harbor/directory fails both the static collision test and the Harbor-free behavior test with the real crash it predicts (ModuleNotFoundError: No module named 'harbor.agents'), and removing the sub-flow's reference to the core fails the deferral test.Known limitation, not addressed here:
docs/contributing/skills-spec.mdxasks for atests.jsonwith four-mode routing tests per skill, and neither skill ships one. It matters more than usual because splitting one skill into two creates the routing ambiguity those tests exist to catch. No CI workflow currently referencesskill-test.pyorskill-cli-lint.py, and 15 of the 19 existing plugin skills also lacktests.json, so this is consistent with the current state of the tree rather than a regression. Happy to add it here if a reviewer would rather it land together.Summary by CodeRabbit
