Lifecyclemodel Automated Builder

Lifecycle Model Automated Builder

Use this skill when the source of truth is a set of existing local process-automated-builder run directories and the next step is to assemble a native lifecyclemodel artifact locally.

Guardrails

• The canonical runtime path is skill -> Node wrapper -> tiangong-lca CLI.
• Persistent build outputs must use an explicit --out-dir; this skill does not choose a default output root.
• For repeatable runs, use an explicit output directory such as /abs/path/artifacts/<case_slug>/....
• The current canonical slices are:
  • tiangong-lca lifecyclemodel auto-build
  • tiangong-lca lifecyclemodel validate-build
  • tiangong-lca lifecyclemodel publish-build
• The supported workflow is CLI-based and local to your build inputs:
  • no Python workflow
  • no MCP transport
  • no remote lifecyclemodel CRUD
  • no reference-model discovery against KB / LLM services
• The skill produces native json_ordered only. It does not emit json_tg, rule_verification, or resulting-process artifacts.
• validate-build and publish-build now exist as dedicated CLI follow-up commands; do not reintroduce those stages inside the skill.
• Only local_runs[] is executable today. Discovery hints may be recorded as deferred notes, but they are not executed inside this skill.

Workflow

1. Prepare a manifest whose core input is local_runs[].
2. Pick an output directory, typically under a path such as /abs/path/artifacts/<case_slug>/....
3. Run node scripts/run-lifecyclemodel-automated-builder.mjs build --input <manifest> --out-dir <dir>.
4. During assembly, preserve TianGong native model conventions from tiangong-lca-next:
   • lifeCycleModelInformation.quantitativeReference.referenceToReferenceProcess
   • technology.processes.processInstance[*].referenceToProcess
   • technology.processes.processInstance[*].connections.outputExchange
   • computed @multiplicationFactor
   • a valid referenceToResultingProcess reference inside json_ordered
5. Review the local outputs:
   • run-plan.json
   • resolved-manifest.json
   • selection/selection-brief.md
   • discovery/reference-model-summary.json
   • models/**/tidas_bundle/lifecyclemodels/*.json
   • models/**/summary.json
   • models/**/connections.json
   • models/**/process-catalog.json
   • reports/lifecyclemodel-auto-build-report.json
6. If the workflow later needs validation or publish handoff, call the dedicated CLI follow-up commands instead of rebuilding those paths inside the skill:
   • node scripts/run-lifecyclemodel-automated-builder.mjs validate --run-dir <dir>
   • node scripts/run-lifecyclemodel-automated-builder.mjs publish --run-dir <dir>
7. If someone asks for remote discovery or AI-assisted model selection, add it as a native tiangong-lca lifecyclemodel ... capability first.

Commands

node lifecyclemodel-automated-builder/scripts/run-lifecyclemodel-automated-builder.mjs build \
  --input lifecyclemodel-automated-builder/assets/example-local-runs.json \
  --out-dir /abs/path/artifacts/<case_slug>/lifecyclemodel-auto-build

node lifecyclemodel-automated-builder/scripts/run-lifecyclemodel-automated-builder.mjs validate \
  --run-dir /abs/path/artifacts/<case_slug>/lifecyclemodel-auto-build

node lifecyclemodel-automated-builder/scripts/run-lifecyclemodel-automated-builder.mjs publish \
  --run-dir /abs/path/artifacts/<case_slug>/lifecyclemodel-auto-build

Troubleshooting

• Local CLI override issues: set TIANGONG_LCA_CLI_DIR or pass --cli-dir only when you intentionally need an unpublished working tree.
• Missing --out-dir: the wrapper requires an explicit output path such as /abs/path/artifacts/<case_slug>/....
• Missing local_runs[]: the current canonical slice only accepts local process-build runs.
• Validation/publish follow-up: use the dedicated CLI subcommands against one existing auto-build run; they work from local build outputs and do not perform remote writes.
• Validation failures on required model fields: inspect references/model-contract.md.
• Topology disagreements: inspect references/source-analysis.md for native lifecycle model conventions.
• If you need remote discovery or writes, add that capability to the native CLI instead of extending this skill with a separate runtime.
