process-scope-statistics

Use this skill when the task is to answer questions like:

• “这些 process 覆盖多少领域/工艺/产品？”
• “当前可见的 state_code=0,100 process 有多少单元过程、多少产品？”
• “给我一个以后可重复跑的 process scope 统计方案”

Workflow

1. Create an output directory first.
2. Ensure TIANGONG_LCA_* is already exported or .env is available in the current working directory.
3. Run node scripts/run-process-scope-statistics.mjs.
4. Review the JSON summaries and Markdown reports in that output directory.
5. If you need a Chinese report, keep the .zh-CN.md output.

Default Statistical Scope

Unless the user says otherwise, use:

• --scope visible
• --state-codes 0,100

visible means “all process rows visible to the current authenticated session”. In practice this typically includes:

• draft rows owned by the current account, such as state_code=0
• publicly visible rows such as state_code=100

Canonical Script

node scripts/run-process-scope-statistics.mjs \
  --out-dir /abs/path/process-scope-stats \
  --scope visible \
  --state-code 0 \
  --state-code 100

Useful options:

• --scope current-user
• --state-code 0
• --state-code 100
• --page-size 200
• --reuse-snapshot

The wrapper delegates to the canonical CLI command:

tiangong process scope-statistics --out-dir /abs/path/process-scope-stats --scope visible --state-code 0 --state-code 100

Compatibility note:

• --state-codes 0,100 is still accepted as a wrapper/CLI alias, but repeatable --state-code flags are the canonical shape.

Outputs

• inputs/processes.snapshot.manifest.json
• inputs/processes.snapshot.rows.jsonl
• outputs/process-scope-summary.json
• outputs/domain-summary.json
• outputs/craft-summary.json
• outputs/product-summary.json
• outputs/type-of-dataset-summary.json
• reports/process-scope-statistics.md
• reports/process-scope-statistics.zh-CN.md

Metric Definitions

Read references/metric-definitions.md when you need the exact counting rules for:

• domain
• craft / route
• unit process
• product

Notes

• This is a read-only statistics skill; it does not save remote edits.
• The skill is a thin wrapper over tiangong process scope-statistics; it does not carry a separate remote runtime or private .env parser.
• The metric layer is deterministic and string-based. It does not try to semantically merge cross-language variants unless they already share the same stable identifier.
