feat(agents): expand ETHOS.md as schema v1 and rename nemo-spec to nemo-ethos - #1518

Conversation
…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>

- Line 248: Update the validation command near the parser checks to emit the
recovery-table token ethos_parse_invalid instead of ethos_invalid, matching the
final verification block and preserving consistent parse-failure reporting.
In
`@packages/nemo_platform_ext/src/nemo_platform_ext/skills/nemo-explore/SKILL.md`:
- Around line 112-119: Update the migration flow after copying files into
agents/<name>-ethos/ to upload the complete directory to the new Ethos Fileset
and verify all expected paths, including agent.yaml and relative artifacts. Only
after successful upload and verification should the confirmation step delete
agents/<name>-spec/ and the <name>-spec Fileset.
- Around line 55-68: Update the front-matter schema table in the Ethos
documentation to include updated_timestamp as a required edit-time field, and
clarify that it is omitted only on the first write. Adjust the statement that
currently describes five front-matter fields so it reflects the added field
while preserving the existing guidance for nemo-ethos.
In `@plugins/nemo-agents/src/nemo_agents_plugin/ethos.py`:
- Around line 98-109: Update required_sections and known_sections to reject
versions greater than ETHOS_SCHEMA_VERSION, in addition to versions below 1, by
raising the same ValueError used for unsupported schema versions. Preserve
returning ETHOS_SECTION_TITLES for the supported version, and add coverage for
ETHOS_SCHEMA_VERSION + 1 in both helpers.

spec.is_file() branch so it runs after either upload path completes. Preserve
the existing NotFoundError handling and ensure sdk.files.delete uses the same
fileset, workspace, and remote path arguments.

Explore was filling Vision from inferred docs. Always confirm Purpose & Outcomes, Principles, and Vision (minimum three questions), keep extra ETHOS headings valid, and show a post-write gut-check so the user can judge the agent quickly. Signed-off-by: Alec Khoury <akhoury@nvidia.com>

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
