tidas-contract-context

name	tidas-contract-context
description	Fetch SDK-backed TIDAS schema, methodology YAML, runtime ruleset, and AI context-pack artifacts through the tiangong-lca CLI. Use before AI authoring or repairing TIDAS process, flow, source, contact, unitgroup, flowproperty, lifecyclemodel, or lciamethod data.

TIDAS Contract Context

Use this skill when an agent needs the authoritative TIDAS contract for AI data import, conversion repair, or source-document authoring.

Boundaries

• This skill is a thin wrapper over tiangong-lca dataset context-pack and tiangong-lca dataset contract get.
• Do not copy schema, methodology YAML, or ruleset files into this skill.
• Do not generate or mutate TIDAS rows here. Authoring and conversion should use CLI or Foundry workflows after the context pack exists.

Required Inputs

• Target TIDAS type: process, flow, source, contact, unitgroup, flowproperty, lifecyclemodel, or lciamethod.
• Output directory under the current task workspace.
• Include list when narrower context is needed: schema, methodology, ruleset.

Commands

Create an AI-ready context pack:

tiangong-lca dataset context-pack \
  --type process \
  --profile ai-import \
  --include schema,methodology,ruleset \
  --out-dir .foundry/workspaces/<task-id>/context/process \
  --json

Create a raw contract artifact pack:

tiangong-lca dataset contract get \
  --type flow \
  --include schema,methodology,ruleset \
  --out-dir .foundry/workspaces/<task-id>/contract/flow \
  --json

Verification

After the command completes, verify these artifacts before using the context:

• outputs/contract-report.json
• outputs/contract-manifest.json
• outputs/schema.json when schema was requested
• outputs/methodology.yaml when methodology is available for the target type
• outputs/runtime-ruleset.json when rules exist for the target type
• outputs/ai-context.json and outputs/ai-context.md for context-pack

The manifest hash values are the durable proof of which contract version the AI saw.
