…mo-ethos Expand the agent Ethos contract from a build-time scaffold into a durable statement of intent that the Analyst and Experimentalist can act on, and finish the naming migration started when AGENT-SPEC.md became ETHOS.md. Schema v2 carries 15 body sections in three tiers. Core sections are a hard error when missing, Intent sections warn and fail under strict mode, and Optional sections are silent. Front matter gains schema_version so v1 files keep parsing unchanged. New sections capture what optimization consumers previously had to guess: Constraints, Trade-offs, Metric Semantics, Principles, and Vision. Purpose and Business Objectives merge into Purpose & Outcomes so the mission and the measurable result stay together. Framework, Model, and Signals retire: Framework served a legacy path with no consumers, Model is implementation detail that belongs in agent.yaml and Constraints, and Signals was consumer configuration that now lives in the Analyst prompt. Budget is deliberately absent to keep run-scoped optimization keys out of the contract. Rename the nemo-spec skill to nemo-ethos and remove the remaining AGENT-SPEC copy across skills, docs, Studio catalog, and rules. Signed-off-by: Alec Khoury <akhoury@nvidia.com>

Finish the spec-to-Ethos terminology migration.
The updated workflow writes and consumes ETHOS.md, but several nearby examples still describe the retired spec artifact. Replace the remaining “from a spec”, “scaffold from spec”, and “spec-handled question” wording in the contributor guide, skill-selection guidance, and try-agent recovery instructions with the approved Ethos terminology.

Define a canonical category source.
Schema v2 has no category field, and the Ethos example has no category list. The skill cannot select smoke-test questions or populate Data Designer categories without inventing data.
Add a structured category source to Ethos, or derive categories from one specified existing section and update the templates to use that contract.

Synchronize the canonical Ethos before overwrite.
The storage contract says the Fileset wins and remote drift must be pulled before editing. The download branch runs only when ethos_new. When both local and canonical files exist, this flow can upload a stale local file over a newer canonical ETHOS.md without comparing contents. Download to a temporary path or compare versions before allowing overwrite.

Include nested Ethos package files in the snapshot.
The build layout stores agent.yaml and related artifacts under agents/<name>-ethos/. The patterns agents/*.yml, agents/*.dd.py, and agents/*.json match only direct children and miss agent.yaml because it is nested and uses .yaml. Option 3 can delete files that the snapshot did not show. Use find agents -type f or explicit nested patterns.

Do not suppress Ethos requirements from the rationale.
Rationalizer.run passes ethos only to the Rationalizer. The Harbor evaluator builds task.inputs["instruction"] from instruction.md, and the AUT receives that instruction without Ethos injection. This guidance can therefore omit required Constraints, Trade-offs, and Principles steps from the rationale. Keep these requirements in Rationalizer context, or include them in every AUT task instruction.

existing platform gateway and secret-handling constraints.

- Line 52: Update the canonical nemo-build-agent example around “from a spec”
and “scaffold from spec” to use the current Ethos terminology consistently with

content.

schema v2 and the current Ethos example do not provide one. Either add
structured categories to the Ethos or explicitly derive them from an existing
section, then update the default-path smoke-test selection and Data Designer
templates to consume that single contract without inventing category data.
In `@packages/nemo_platform_ext/src/nemo_platform_ext/skills/nemo-ethos/SKILL.md`:
- Line 14: Update the nemo-ethos skill trigger list by removing the shadowed
“write ETHOS.md” phrase, while retaining the unique “write agent ethos” trigger
for this intent.
- Around line 58-61: Update the Ethos synchronization flow around the ethos_new
branch so that when both local and canonical ETHOS.md files exist, the canonical
copy is downloaded to a temporary location or otherwise compared before any
upload. Only permit overwriting the Fileset after confirming the local file is
current; preserve the existing behavior for cases where either copy is absent.

Use one resolved workspace for upload and pre-flight.
When WORKSPACE is unset, nemo-ethos uploads to the active workspace, but Step 7 checks --workspace "${WORKSPACE:-default}". A non-default active workspace can therefore report the Ethos Fileset as missing. Pass the same resolved workspace to both commands and cover this case in tests.

Verify the new package before deleting the legacy Fileset.
The flow copies remaining files into the local *-ethos directory and then deletes the *-spec directory and Fileset. It does not upload or verify those copied files in the new Ethos Fileset. A failed or incomplete copy can therefore lose agent.yaml or relative artifacts from the only recovery source.
Upload the complete migrated bundle and verify the expected paths before deletion.

Summary
ETHOS.mdwas a build-time scaffold: enough to generate a NAT workflow, not enough to record what "better" means for a given agent. This PR expands that file into a durable intent contract with 15 required body sections, treated as schema version 1, and finishes the naming migration fromnemo-spec/AGENT-SPEC.mdstarted in #1412.Coding agents that find a leftover spec package read it as prior answers, write
ETHOS.mdwithnemo-ethos, and delete the spec package after you confirm.nemo-explorescans the repository first, then asks at least three intent questions, always confirming Purpose & Outcomes, Principles, and Vision. Afternemo-ethoswrites the file, it states a short gut-check of the agent. Extra headings and YAML keys are allowed. Analyst and Experimentalist consumers are unchanged.Changes
