Inline comments:
In `@docs/agents/scan-trace-data.mdx`:
- Around line 31-32: Update the incident-response guidance near the credential
cleanup instructions to separate credential rotation or revocation from
investigation: instruct operators to preserve evidence and investigate prior
access before performing cleanup, while still rotating or revoking the leaked
credential promptly.
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/api/v2/runs.py`:
- Around line 196-197: Update _reject_project_source to fail closed when
NemoEntityNotFoundError occurs: mark the project source as rejected or otherwise
stop apply_mitigation from continuing, rather than returning with an unknown
source type. Ensure a missing manifest cannot cause mitigation to be written to
an unrelated Agent sharing the manifest name.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/model_preflight.py`:
- Line 54: Update probe_models to validate that base_url uses HTTPS before
constructing the Authorization header, rejecting non-HTTPS endpoints before any
Bearer token is attached. Preserve the existing empty-header behavior when no
api_key is provided.
In `@plugins/nemo-agent-hardener/tests/unit/test_init_cli.py`:
- Line 4: Add a collected test_ function in the init CLI test module that
invokes the init flow using the existing _project and _patch_cli fixtures, then
asserts both the captured argv and manifest-create payload. Keep the test
focused on the BYO/custom-image launch mode.
In `@plugins/nemo-agent-hardener/web/src/api/filesets.ts`:
- Line 77: Update the onProjectSelected success handler to populate the form
state’s env field from facts.env, ensuring submission’s data.env includes the
inspected environment values.
In `@plugins/nemo-agent-hardener/web/src/components/hitlTypes.ts`:
- Line 49: Update the prompt parsing logic around the interview and review casts
in hitlTypes.ts (the symbols InterviewPrompt and the review prompt type) to
validate all required prompt, question, option, and suite-row fields before
returning them. Reject invalid interview data, including a numeric round without
a valid questions array, and invalid review data without a valid suite array so
InterviewPanel and BenignSuiteEditor receive only safe shapes; apply the same
validation at both cited sites in hitlTypes.ts (lines 49 and 59).
In
`@plugins/nemo-agent-hardener/web/src/routes/NewAgentHardenerManifestRoute/index.tsx`:
- Around line 92-96: Update the agent inspection and project upload callbacks
around the onSuccess handlers to ignore results from obsolete selections or
uploads. Track the active selection/upload generation or source identity, and
validate it before every setValue, projectFileset, and derived-field state
update so late callbacks cannot overwrite newer state; preserve current updates
for the active operation.
In `@web/packages/studio/e2e-tests/agent-hardener.test.ts`:

In `@plugins/nemo-agent-hardener/examples/langgraph-victim/README.md`:
- Line 22: Update the README section before “## Running it” to document that the
platform secret named INFERENCE_API_KEY must be created before running the
example; clarify that the --secrets flag only references the secret and does not
create it.
- Line 12: Update the fenced code block in the README to include the text
language tag, changing the opening fence to specify text while preserving the
existing file listing content.
In `@plugins/nemo-agent-hardener/openapi/openapi.yaml`:
- Around line 1853-1856: Update the docstrings for ApplyMitigationRequest,
ApplyMitigationResponse, and ComposeDefenseResponse in the schema source to
describe guardrails_toml as the Relay plugin-config TOML document instead of
hardened workflow YAML, then regenerate the OpenAPI specification.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/agent_resolver.py`:
- Around line 582-583: Update resolve_agent_to_manifest so shipped_dockerfile
and download_agent_bundle share one temporary directory for the
{workspace}/{name}-ethos fileset instead of downloading it twice. Keep that
directory alive through both Dockerfile inspection and bundle staging, then
clean it up after both operations complete.
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/cli/lifecycle.py`:
- Around line 234-236: Remove the unused assume_yes option from the init
command, including its --yes/-y CLI aliases, since init never prompts or reads
this value. Keep the remaining init options and server-side behavior unchanged.
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/model_config.py`:
- Line 55: Update the API schema description associated with WarGameModels so it
lists the model groups as attack, analysis, and safety instead of attack,
analysis, and agent, then regenerate the OpenAPI client.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/model_preflight.py`:
- Line 73: Update the response parsing around resp.json() so it verifies the
decoded JSON is a dictionary before accessing data. For non-object responses
such as arrays, use the existing empty-list fallback and preserve the
best-effort preflight behavior.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/project_resolver.py`:
- Around line 221-228: Validate the user-supplied dockerfile path in the project
resolver before constructing or reading chosen, rejecting absolute paths and any
path whose resolved location is outside project_root. Preserve the existing
unresolved response for invalid or missing files, and ensure only files
contained within the uploaded bundle are processed.
In `@plugins/nemo-agent-hardener/web/pnpm-workspace.yaml`:
- Line 5: Update the allowBuilds entry for `@nvidia/foundations-react-core` in the
pnpm workspace configuration to use a Boolean value, true or false, instead of
the placeholder string, while preserving the repository’s intended build-script
policy.
In `@plugins/nemo-agent-hardener/web/src/components/TargetPanel.tsx`:
- Line 55: Update the rendering logic around the onRefresh conditional to retain
the source-type branch: render project_fileset for project manifests, and render
unknown with the refresh action only for agent-backed manifests. Keep refresh
unavailable for project manifests.
In `@plugins/nemo-agent-hardener/web/src/formValues.ts`:
- Line 19: Update the environment-entry parsing logic to trim the key before
validating it, and return null when the trimmed key is empty; otherwise return
the trimmed key and value tuple. Preserve the existing delimiter handling and
value trimming.

Nitpick comments:
In `@docs/agents/add-guardrails.mdx`:
- Around line 10-24: Reorder the documentation so prerequisites appear before
the main content on the Guardrails and Governance pages, and add prerequisite
sections to the CLI Reference and Troubleshooting pages. Preserve the existing
content while ensuring operator instructions follow the required host setup,
including the guarded VirtualModel and agent llms guidance.
In `@plugins/nemo-agent-hardener/examples/langgraph-victim/README.md`:
- Line 54: Add a “Next Steps” section to the README with links to the Agent
Hardener governance and troubleshooting documentation, following the
repository’s Markdown conventions without changing other content.
In `@plugins/nemo-agent-hardener/examples/other-victim/README.md`:
- Around line 22-35: Add a prerequisites section before “## Running it” in both
example README files, listing the NeMo CLI, Docker, OpenShell, a running
platform with the jobs controller, and an inference credential/provider, and
link to the plugin README’s setup instructions. Keep the existing running
commands unchanged.
In `@plugins/nemo-agent-hardener/examples/README.md`:
- Around line 6-40: Restructure the examples overview, Hermes, and LangChain
documentation pages to follow Diátaxis: add Prerequisites at the beginning and
Next Steps links at the end. Keep the overview explanatory, retain Hermes and
LangChain as how-to guides, and add Python SDK and CLI tabs for supported
operations using the agent_hardener manifests.create, synth_benign, and run
APIs. Move Relay and manifest-derivation rationale into linked explanation
documentation.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/api/v2/manifests.py`:
- Around line 83-84: Remove the unused _run_agent_hardener, _SubprocessError,
and _SubprocessTimeout symbols from manifests.py, along with any imports and
constants that become unused; leave the manifest functionality and other
referenced code unchanged.
In `@plugins/nemo-agent-hardener/web/src/components/useSanityCheck.ts`:
- Line 76: In the request construction within useSanityCheck, remove the
unnecessary as never cast and pass the spec object directly. Rely on the
structural compatibility between SanityCheckSpec and the generated WarGameSpec
so compile-time validation remains enabled.
In
`@plugins/nemo-agent-hardener/web/src/routes/NewAgentHardenerManifestRoute/index.tsx`:
- Line 46: Update the React imports in the NewAgentHardenerManifestRoute module
to make FC a type-only import, while keeping useEffect, useMemo, and useState as
runtime imports.
In `@web/packages/studio/e2e-tests/agent-hardener.test.ts`:
- Line 47: Update the plugin response handling in the test to use the maintained
PluginManifest type and validate the parsed response with isValidPluginManifest
before calling find. Remove the duplicated inline response shape and preserve
the existing plugin lookup behavior only for validated manifests.

Inline comments:
In `@docs/agents/scan-trace-data.mdx`:
- Around line 31-32: Update the incident-response guidance near the credential
cleanup instructions to separate credential rotation or revocation from
investigation: instruct operators to preserve evidence and investigate prior
access before performing cleanup, while still rotating or revoking the leaked
credential promptly.
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/api/v2/runs.py`:
- Around line 196-197: Update _reject_project_source to fail closed when
NemoEntityNotFoundError occurs: mark the project source as rejected or otherwise
stop apply_mitigation from continuing, rather than returning with an unknown
source type. Ensure a missing manifest cannot cause mitigation to be written to
an unrelated Agent sharing the manifest name.
In `@plugins/nemo-agent-hardener/tests/unit/test_init_cli.py`:
- Line 4: Add a collected test_ function in the init CLI test module that
invokes the init flow using the existing _project and _patch_cli fixtures, then
asserts both the captured argv and manifest-create payload. Keep the test
focused on the BYO/custom-image launch mode.
In `@plugins/nemo-agent-hardener/web/src/api/filesets.ts`:
- Line 77: Update the onProjectSelected success handler to populate the form
state’s env field from facts.env, ensuring submission’s data.env includes the
inspected environment values.
In
`@plugins/nemo-agent-hardener/web/src/routes/NewAgentHardenerManifestRoute/index.tsx`:
- Around line 92-96: Update the agent inspection and project upload callbacks
around the onSuccess handlers to ignore results from obsolete selections or
uploads. Track the active selection/upload generation or source identity, and
validate it before every setValue, projectFileset, and derived-field state
update so late callbacks cannot overwrite newer state; preserve current updates
for the active operation.
In `@web/packages/studio/e2e-tests/agent-hardener.test.ts`:
- Line 127: Update the test containing agentHardener.gotoManifest('byo-ledger')
to provision the byo-ledger manifest before navigation and delete it during test
cleanup, ensuring the test is self-contained on a clean platform.
In `@web/packages/studio/e2e-tests/pages/agent-hardener.ts`:
- Line 22: Update the public page-object members in agent-hardener.ts by
importing Locator as a type from `@playwright/test`, annotating navItem, dataRows,
and sourceToggle with Locator, and declaring Promise<void> return types on the
remaining asynchronous methods such as gotoRuns. Preserve the existing behavior
and implementations.

Outside diff comments:
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/cli/lifecycle.py`:
- Line 301: Update the manifest summary formatting to read the defined
source_type field instead of the nonexistent workflow field, preserving the
existing fallback when source_type is absent.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/model_preflight.py`:
- Line 54: Update probe_models to validate that base_url uses HTTPS before
constructing the Authorization header, rejecting non-HTTPS endpoints before any
Bearer token is attached. Preserve the existing empty-header behavior when no
api_key is provided.
In `@plugins/nemo-agent-hardener/web/src/components/hitlTypes.ts`:
- Line 49: Update the prompt parsing logic around the interview and review casts
in hitlTypes.ts (the symbols InterviewPrompt and the review prompt type) to
validate all required prompt, question, option, and suite-row fields before
returning them. Reject invalid interview data, including a numeric round without
a valid questions array, and invalid review data without a valid suite array so
InterviewPanel and BenignSuiteEditor receive only safe shapes; apply the same
validation at both cited sites in hitlTypes.ts (lines 49 and 59).

Minor comments:
In `@docs/agents/add-guardrails.mdx`:
- Line 160: Ensure the documentation pages end with the required “## Next Steps”
section: add it to add-guardrails.mdx and troubleshooting.mdx, and rename the
existing “Related Topics” section in cli-reference.mdx while preserving its
valid workflow links.
In `@docs/agents/scan-trace-data.mdx`:
- Line 51: Update the documentation around the nemo files list
nemo-agent-telemetry command so it is labeled as telemetry inspection rather
than a scan, unless a supported CLI scan command is provided instead.
- Line 34: Reorder the scan-trace-data page so the ## Prerequisites section
appears before ## What the Scan Looks For, and rename the final ## Related
Topics heading to ## Next Steps. Preserve the existing section content and
navigation.
In `@plugins/nemo-agent-hardener/examples/langgraph-victim/README.md`:
- Line 22: Update the README section before “## Running it” to document that the
platform secret named INFERENCE_API_KEY must be created before running the
example; clarify that the --secrets flag only references the secret and does not
create it.
- Line 12: Update the fenced code block in the README to include the text
language tag, changing the opening fence to specify text while preserving the
existing file listing content.
In `@plugins/nemo-agent-hardener/openapi/openapi.yaml`:
- Around line 1853-1856: Update the docstrings for ApplyMitigationRequest,
ApplyMitigationResponse, and ComposeDefenseResponse in the schema source to
describe guardrails_toml as the Relay plugin-config TOML document instead of
hardened workflow YAML, then regenerate the OpenAPI specification.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/agent_resolver.py`:
- Around line 582-583: Update resolve_agent_to_manifest so shipped_dockerfile
and download_agent_bundle share one temporary directory for the
{workspace}/{name}-ethos fileset instead of downloading it twice. Keep that
directory alive through both Dockerfile inspection and bundle staging, then
clean it up after both operations complete.
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/cli/lifecycle.py`:
- Around line 234-236: Remove the unused assume_yes option from the init
command, including its --yes/-y CLI aliases, since init never prompts or reads
this value. Keep the remaining init options and server-side behavior unchanged.
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/model_config.py`:
- Line 55: Update the API schema description associated with WarGameModels so it
lists the model groups as attack, analysis, and safety instead of attack,
analysis, and agent, then regenerate the OpenAPI client.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/model_preflight.py`:
- Line 73: Update the response parsing around resp.json() so it verifies the
decoded JSON is a dictionary before accessing data. For non-object responses
such as arrays, use the existing empty-list fallback and preserve the
best-effort preflight behavior.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/project_resolver.py`:
- Around line 221-228: Validate the user-supplied dockerfile path in the project
resolver before constructing or reading chosen, rejecting absolute paths and any
path whose resolved location is outside project_root. Preserve the existing
unresolved response for invalid or missing files, and ensure only files
contained within the uploaded bundle are processed.
In `@plugins/nemo-agent-hardener/web/pnpm-workspace.yaml`:
- Line 5: Update the allowBuilds entry for `@nvidia/foundations-react-core` in the
pnpm workspace configuration to use a Boolean value, true or false, instead of
the placeholder string, while preserving the repository’s intended build-script
policy.
In `@plugins/nemo-agent-hardener/web/src/components/TargetPanel.tsx`:
- Line 55: Update the rendering logic around the onRefresh conditional to retain
the source-type branch: render project_fileset for project manifests, and render
unknown with the refresh action only for agent-backed manifests. Keep refresh
unavailable for project manifests.
In `@plugins/nemo-agent-hardener/web/src/formValues.ts`:
- Line 19: Update the environment-entry parsing logic to trim the key before
validating it, and return null when the trimmed key is empty; otherwise return
the trimmed key and value tuple. Preserve the existing delimiter handling and
value trimming.

Minor comments:
In `@docs/agents/governance/cli-reference.mdx`:
- Line 77: Update the `--name` option documentation in the CLI reference to
state that `init --project-dir` defaults the manifest name to the project
directory basename, while the other initialization path defaults it to the agent
name.
In `@docs/agents/governance/index.mdx`:
- Around line 73-75: Update the apply-mitigation guidance in
docs/agents/governance/index.mdx lines 73-75 and
docs/agents/governance/apply-mitigations.mdx lines 120-121 to state that
applying a fix attempts to refresh the frozen manifest, but the refresh can
fail; instruct users to inspect the response detail and run nemo agent-hardener
refresh manually before the next run when necessary.
In `@docs/agents/governance/run-a-war-game.mdx`:
- Line 56: Add a Python SDK tab alongside the existing CLI tab set in the
run-a-war-game how-to, covering equivalent manifest, benign-suite, and run
workflows while preserving the current nemo agent-hardener examples.
In `@docs/agents/scan-trace-data.mdx`:
- Around line 36-44: Move the prerequisites section to the top of the page
before the scan description in docs/agents/scan-trace-data.mdx (lines 36-44),
and before the workflow introduction in
docs/agents/governance/run-a-war-game.mdx (lines 25-49). Preserve the existing
prerequisite content and ordering within each page.
- Line 130: Rename the “Related Topics” section heading to “Next Steps” and keep
it at the end with the existing cross-links intact.
- Around line 52-54: Update both the CLI and Python SDK examples in the tab-set
so they invoke the supported scan operation before listing telemetry or
findings; preserve the existing listing steps after the scan completes and
ensure each tab demonstrates the complete scan task.
In `@plugins/nemo-agent-hardener/examples/langgraph-victim/agent.py`:
- Around line 67-76: Update python_executor to avoid rebinding process-global
sys.stdout while executing code concurrently; use an execution-local output
capture mechanism so overlapping calls cannot capture each other’s output, while
preserving exception reporting and the "(no output)" fallback.
In `@plugins/nemo-agent-hardener/examples/other-victim/README.md`:
- Line 6: Add a prerequisites section before “## Running it” and a final “Next
Steps” section to both README files:
plugins/nemo-agent-hardener/examples/other-victim/README.md (line 6) and
plugins/nemo-agent-hardener/examples/relay-victim/README.md (line 4). Keep each
page focused as a HOW-TO and move conceptual explanation to linked explanation
pages.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/api/v2/manifests.py`:
- Around line 6-11: Update the manifests API docstring to describe the current
inspection and manifest-building flow rather than claiming POST /manifests or
the project source runs init. Reference inspect_project and
build_project_manifest_dict, and preserve the documented required-field
validation behavior.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/api/v2/schemas.py`:
- Line 261: Update the docstrings for ApplyMitigationRequest and
ComposeDefenseResponse to describe Relay guardrail TOML instead of workflow YAML
or composed workflow + policy, ensuring the generated OpenAPI descriptions match
the current request and response payloads.
- Line 190: Update the description metadata on InspectProjectResponse.egress to
use clear, grammatically correct wording that accurately describes the hosts
associated with the project's own files.
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/config.py`:
- Around line 157-158: Update the package-spec examples in the configuration
help text to use the actual distribution name and a version example consistent
with the default nvidia-agent-hardener>=0.0.11 requirement, while preserving the
local path/VCS URL example.
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/jobs/defenses.py`:
- Line 83: Update the component configuration logic around config["guardrails"]
so it modifies only configurations whose existing guardrails value is a list; do
not create or add an empty guardrails list to components that lack guardrails,
and preserve unrelated component configuration.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/model_preflight.py`:
- Line 73: Update the response parsing in the model preflight function so it
verifies resp.json() returns a dict before accessing data. For JSON arrays or
scalar values, use the existing empty-data fallback and preserve the function’s
never-raises contract.
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/project_resolver.py`:
- Around line 221-228: Validate that the resolved chosen path remains within
project_root before any read_text() call or subsequent relative_to() use in the
dockerfile resolution flow. Update the dockerfile handling around chosen and
preserve the existing unresolved response for invalid or non-file paths.
In `@plugins/nemo-agent-hardener/web/pnpm-workspace.yaml`:
- Line 5: Replace the generated allowBuilds placeholder for
`@nvidia/foundations-react-core` with an explicit boolean value, true or false, to
define the package’s build-script policy.
In `@plugins/nemo-agent-hardener/web/src/components/HardenPanel.tsx`:
- Line 273: Update the composed preview state handling in HardenPanel so it
preserves both composed.guardrails_toml and composed.policy_yaml instead of
discarding policy_yaml. Extend the Preview composed rendering to display the
preserved policy YAML through a ConfigDiff, including policy-only and mixed
selections while retaining guardrails preview behavior.
In `@plugins/nemo-agent-hardener/web/src/components/TargetPanel.tsx`:
- Around line 68-69: Update the Agent display in TargetPanel to branch on the
manifest source type: for project manifests using project_fileset, display the
project fileset target instead of the unknown fallback; preserve the existing
agent display for other manifest types.
In `@plugins/nemo-agent-hardener/web/src/components/useMitigations.ts`:
- Line 94: Update the TOML value extraction in the relevant mitigation parsing
logic around the match returning match[1] or match[2] so escaped strings are
decoded before storage and rendering, including quoted and newline escapes. Add
a fixture covering quoted and multiline system_instructions values.
In `@plugins/nemo-agent-hardener/web/src/formValues.ts`:
- Line 19: Update the entry parsing logic around the visible return expression
to trim the key portion before validating its delimiter position, and return

Nitpick comments:
In
`@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/api/v2/manifests.py`:
- Around line 83-84: Remove the unused subprocess helpers from manifests.py:
_run_agent_hardener, _SubprocessError, _SubprocessTimeout, and
_SUBPROCESS_TIMEOUT_SECONDS. Clean up any imports or references used only by
these definitions, leaving the remaining manifest API behavior unchanged.
In `@plugins/nemo-agent-hardener/src/nemo_agent_hardener_plugin/jobs/manifest.py`:
- Around line 122-126: Remove the unreachable warning branch and its
“unavailable (the agent has no workflow)” message from the manifest handling
after constructing entries from DEFENDER_ENTRIES. Keep the guardrails entry
handling and normal enabled configuration behavior unchanged.
In `@plugins/nemo-agent-hardener/tests/unit/test_agent_resolver.py`:
- Around line 248-256: The test test_resolve_omits_egress_key_when_none should
also verify derived egress reaches resolved.egress when no caller egress is
supplied. Configure the agent fixture with a network MCP server or model
base_url, then assert the corresponding derived host appears in resolved.egress
while preserving the existing manifest and port assertions.
In `@plugins/nemo-agent-hardener/web/src/api/filesets.ts`:
- Line 60: In plugins/nemo-agent-hardener/web/src/api/filesets.ts at lines 60-60

| ### Why the four extra flags | ||
|
|
||
| `init` derives what the Dockerfile *states* and warns about the rest rather than guessing. The | ||
| model host and API key live in `agent.py`, and this image installs to the system Python rather than | ||
| a venv — so four things cannot be derived, and each fails differently if omitted: the credential | ||
| name (victim starts, then fails its first model call), the egress host (default-deny sandbox drops | ||
| model traffic mid-run), the absolute start command (OpenShell replaces `PATH`, so bare `python` | ||
| never resolves), and the interpreter glob (the egress policy would match no process, granting | ||
| nothing). | ||
|
|
||
| If your own project declares these in the Dockerfile, `init` picks them up and you pass nothing. |

This accepts an absolute path or a path containing ... project_root / dockerfile can therefore resolve outside the uploaded bundle, and read_text() below will read that file. Resolve both paths and reject the selection unless it remains inside project_root before checking or reading it. Please add tests for both absolute paths and parent traversal.

This enables Apply while the manifest query is still loading or has failed because isProjectSource is then undefined. That creates a window where a project manifest can be applied to a same named registered agent. Keep the action disabled until the query succeeds and explicitly confirms a non project source.

Removing the selected file does not invalidate the upload already in flight. Its success callback can still restore the fileset and derived values after the UI has cleared the selection. Increment selectionRef.current before clearing state and add a test for removal during upload.

Iron Swarm's contract is now a directory with a runnable agent in it — a config plus the Dockerfile that serves it — not a NAT project it has to interpret. All nemo-agents-spec-v1 knowledge stays on this side of the line, which is also the only place it can live: reading the spec means importing nemo-agents-plugin, and that pins six nvidia-nat-* distributions iron-swarm exists to be free of. The image is not hand-rolled. render_fabric_dockerfile(sandbox_runtime='openshell') is the platform's own packaging pipeline, and the openshell sandbox profile already bakes in exactly what Iron Swarm's sandbox needs — a non-root 'sandbox' user, iproute2, nftables — so the agent under test is packaged the way a deployed one is, rather than by a second recipe that could drift. Reverses one NAT-era behaviour deliberately: the telemetry strip is gone. NAT configs carried a nemo_files exporter the sandboxed victim could not resolve, so it was dropped. A Relay victim's telemetry is what Iron Swarm reads to see which tools an attack reached — stripping it would make every run report an uninstrumented victim. inject_gateway_url now delegates to the platform's own implementation instead of a local copy that had started to drift: it still rewrote NAT llms entries, which a nemo-agents-spec-v1 agent does not have.

Deletes the project-upload path end to end: the inspect endpoint and its response model, the launch-mode validation, the project manifest builder, the CLI's --project-dir/--workflow/--dockerfile/--binary flags, and the SDK's inspect(). It existed to carry a NAT project, and Iron Swarm no longer runs one. source_type and launch_mode go with it. With one source and one launch mode there is nothing left to discriminate, and a field that can only hold one value invites code that pretends otherwise. The capability is relocated, not lost: an agent with custom tool code reaches the platform as an MCP server, which keeps it registrable and therefore war-gameable. Agents whose orchestration cannot be expressed as config are war-gamed from the iron-swarm CLI directly, which takes any Relay-connected agent.

The harden flow now carries a plugins.toml end to end: compose, sanity-check and apply. Applying re-homes the guardrail onto the agent entity as a Relay component instead of overwriting a NAT workflow. Fixes the validate-only seeding, which still wrote the composed defense to agent.project_dir/agent.workflow -- fields that no longer exist, so a sanity check would have silently measured the unhardened victim.

Follows the library rename ahead of its public PyPI release. The plugin becomes nemo-agent-hardener, the CLI `nemo agent-hardener`, the service and Studio bundle agent-hardener, and the SDK attribute client.agent_hardener. Clean break, no aliases: entity types, job ids, permission namespaces, the secret name and the NEMO_AGENT_HARDENER_* config vars all move together, as do the paths into the library's renamed .agent-hardener run tree. The bare word swarm stays where it names the live-events graph rather than the product. Signed-off-by: Koral Chapnik Verbun <kchapnikverb@nvidia.com>
Secure Agents covered two unrelated jobs on one page: wiring guardrails onto an agent's model path, and scanning trace data for PII and leaked credentials. They sit at opposite ends of the lifecycle and share nothing but a fileset. Split it into two published pages named for the job each does: - Add Guardrails to an Agent (docs/agents/add-guardrails.mdx) - Scan Trace Data (docs/agents/scan-trace-data.mdx) Re-target the 8 inbound links to whichever half each one wanted, and redirect /documentation/agents/secure-agents to the guardrails page. Add Agent Governance as a gated subsection under Agents, covering the Iron Swarm attack/defend/validate cycle: overview, run a war-game (registered agents and unregistered projects), review and apply mitigations, CLI reference, and troubleshooting. Registered in gated-nav.yml, so Fern does not build or index it and no published page links into it. Also normalize the lowercase "Next steps" heading in agents/optimization.mdx. make docs-check and make docs-broken-links pass; the 7 remaining broken links (opensandbox, studio/plugins) predate this change. Signed-off-by: Yamini <ykagal@gmail.com>
Fern derives slugs from page titles, so the gated pages resolved at /agents/agent-governance/iron-swarm-cli-reference while every cross-link between them used /agents/governance/cli-reference. Nothing caught this: gated pages are not built, so links among them are never validated. Pin the section and page slugs so the URLs match what the pages link to. Move Add Guardrails up beside the other single pages. It sat between two collapsible sections, inherited from where Secure Agents was, which left it stranded in the sidebar. Order now follows the lifecycle: deploy, guardrail, observe, scan, then the two sections. Shorten the sidebar label to match the two-word rhythm of its siblings; the page title and URL are unchanged. Signed-off-by: Yamini <ykagal@gmail.com>
Renames the gated governance docs to Agent Hardener, and fixes what they say. Most of the corrections predate the rename: the apply-mitigation example posted workflow_yaml, which the API has never accepted and which returns 422; init was documented with a --workflow flag that does not exist and as an interview it never runs; doctor was described as four checks when it runs five; --binary was called a requirement; nvidia-nat was listed as mandatory; and --safety-model was said not to be preflighted when it is. Also states two limits the pages did not mention: applying records guardrails on the agent but does not yet activate them on a redeploy, and policy_yaml is composed for review rather than applied.

--safety-model's help said it was not preflighted; jobs/run.py probes it with the attack and analysis groups. The project inspector warned 'No hosts named in the project's own files' when it had only read the Dockerfile — the run scans the project source too, so the warning sent readers looking for a problem that was not there.

The library's distribution name is now nvidia-agent-hardener, following Kitmaker's naming convention for NVIDIA packages on public PyPI. Only the distribution name changed; the import package and the agent-hardener console script the plugin invokes are unaffected. nvidia-agent-hardener 0.0.10 is published to nv-shared-pypi-local, so this resolves today for anyone with NEMO_AGENT_HARDENER_INDEX_URL pointed there.

0.0.11 drops the unused pydantic-ai dependency, which also removes mcp, cryptography and their transitive tail - 128 packages down to 77 - and clears every High severity finding in the OSS scan.

Summary
Renames the Iron Swarm plugin to Agent Hardener, matching the library rename that
has already merged in the
agent-hardenerrepo (formerlyiron-swarm) ahead of itspublic PyPI release. Clean break, no aliases. Also folds in the gated Agent
Governance docs and corrects what they say about the code.
This branch contains the two commits from #1607. Its author's branch is an
ancestor of this one, so #1607 can be closed as superseded once this merges — its
commits keep their original authorship here.
