Process Automated Builder

Scope

• Prepare one local process_from_flow run from a request or reference-flow input.
• Reopen an existing run to write deterministic resume metadata.
• Prepare one local publish bundle from an existing run.
• Prepare a deterministic batch of local process-build runs.

This skill uses the CLI only. Legacy alternate runtimes are not part of the supported path.

Canonical Runtime

1. Read references/workflow-map.md and references/operations-playbook.md.
2. Choose an explicit output directory, for example /abs/path/artifacts/<case_slug>/....
3. Use node scripts/run-process-automated-builder.mjs auto-build... --out-dir <dir> to create one local run root.
4. Continue with resume-build, publish-build, or batch-build as needed, passing --run-dir or --out-dir explicitly.
5. If a missing capability is discovered, add a native tiangong process... command in tiangong-lca-cli first. Do not add new business runtime inside this skill.

Parallel Execution Contract

• Run-level parallel: multiple flow inputs can run concurrently, but each run must use a distinct run_id.
• In-run parallel: do not run multiple writers against the same run_id.
• Single-writer rule:

- never let multiple agents write the same <run_dir>/cache/process_from_flow_state.json - within one run_id, only one active writer process is allowed at a time - enforcement is code-level through the CLI state lock

Runtime Requirements

• The wrapper runs the published CLI by default through npm exec --yes --package=@tiangong-lca/cli@latest -- tiangong.
• Set TIANGONG_LCA_CLI_DIR or pass --cli-dir only when you need a local CLI working tree for dev/CI.
• The wrapper requires explicit output paths instead of relying on cwd/artifacts/... defaults.
• For repeatable runs, use an explicit output root such as /abs/path/artifacts/<case_slug>/....
• The current canonical commands prepare local run outputs and do not depend on legacy private runtimes.
• If a future native CLI command needs additional env, document it in tiangong-lca-cli first and keep this skill as a thin caller only.

Process Name Contract

• Any generated process payload must preserve the four-part process name object: name.baseName, name.treatmentStandardsRoutes, name.mixAndLocationTypes, name.functionalUnitFlowProperties.
• baseName, treatmentStandardsRoutes, and mixAndLocationTypes are schema-required in current TianGong process payloads. Keep the keys even when one field is semantically empty; do not collapse the whole reference-flow short description back into baseName.
• When name splitting is ambiguous, align with ../lifecycleinventory-review/profiles/process/references/process-review-rules.md instead of inventing a one-off local convention.

Fast 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 or --run-dir: the wrapper requires an explicit output path such as /abs/path/artifacts/<case_slug>/....
• Missing --input / --flow-file: new runs need one explicit request or reference-flow input.
• Run-level conflicts: do not reuse the same run_id across concurrent writers.
• Publish preparation issues: inspect stage_outputs/10_publish/ and cache/agent_handoff_summary.json before touching downstream publish flow.
• If a required step is missing, add it as a native tiangong process... command instead of reintroducing a legacy runtime here.
