Tiangong KB Ingest

Boundary

Use the Tiangong AI CLI through the exact reviewed entrypoint npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai by default, so users do not need a preinstalled CLI. The agent may orchestrate CLI schema, scan, metadata dry-run, and bulk commands, but it must not call backend databases or storage systems directly.

CLI-owned behavior:

• tiangong-ai kb ingest bulk
• tiangong-ai kb ingest bulk scan
• tiangong-ai kb ingest metadata dry-run
• tiangong-ai kb ingest status
• tiangong-ai kb collections list
• tiangong-ai kb collections schema
• SQLite checkpoint and resume
• concurrency/retry
• JSON output
• API key and env handling

Skill-owned behavior:

• choose this workflow when the user wants to upload local files/folders into Tiangong KB
• choose the safest collection selector
• generate a conservative rule_mode: layered metadata map from collection schema plus folder scan when the user did not pass --metadata-map
• run CLI metadata dry-run before bulk run and pass the generated metadata map into bulk ingest
• explain returned duplicate, existingDocumentId, document status, job id, request id, and idempotency key
• keep backend secrets and storage/search systems out of the agent workflow

Short Workflow

1. Confirm the local file or folder path exists.
2. Pick one collection selector:
   • prefer --collection-name or TIANGONG_KB_DEFAULT_COLLECTION_NAME when the user gives a unique display name
   • use --collection-key, --collection-path, or --collection-id only when the user provides an exact selector
3. Load dotenv defaults from the target path directory when present:
   • for a file, read .env from the file's parent directory
   • for a folder, read .env from that folder
   • loaded dotenv values fill only unset environment variables; explicit user inputs passed as CLI flags take precedence
4. For a first check, run npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb collections list --json.
5. For bulk/upload runs without --metadata-map, generate metadata-map.yaml:
   • call CLI collection schema through the Tiangong KB ingest API
   • call CLI bulk scan for folder structure
   • write a layered metadata map with base filesystem fields plus conservative domain/detector rules
   • run CLI metadata dry-run against the generated map
6. Ingest with npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb ingest bulk <path> --json; pass --metadata-map metadata-map.yaml unless a metadata map is already provided or the user explicitly asks to skip metadata-map generation.
7. For long runs, tune --window-size, --top-up-max, --upload-concurrency, --retries, and --state; do not add --max-polls unless the user explicitly wants a bounded monitoring run.
8. If the user asks to verify later state, use npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb ingest status <document-id-or-job-id> --json.
9. Report only current CLI output and backend response fields. Do not infer success from direct database queries.

Metadata Map Minimum

When generating metadata-map.yaml, start from this conservative layered map and add only collection-specific fields that the schema requires:

version: 1
rule_mode: layered
defaults:
  source: local_bulk_upload
layers:
  - name: base
    merge: all
    rules:
      - name: filesystem
        match:
          glob: "**/*"
        fields:
          relative_path:
            source: relative_path
          filename:
            source: filename
          filename_stem:
            source: filename_stem
          ext:
            source: ext
          path_depth:
            source: path_depth
          top_dir:
            source: top_dir
          parent_dir:
            source: parent_dir

For required schema fields not covered by path rules, add safe defaults under defaults: prefer other when it is an enum value, otherwise the first enum value, 0 for numbers, false for booleans, 1970-01-01 for dates, and unknown for strings.

Validate before upload:

npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb ingest bulk scan /path/to/folder --json
npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb collections schema --collection-key course/thu_humanities --json
npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb ingest metadata dry-run /path/to/folder --metadata-map metadata-map.yaml --json

For offline validation with a captured schema, pass --schema-file schema.json to metadata dry-run.

Examples

Upload one file:

npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb ingest bulk /path/to/document.pdf --json

Upload a folder:

npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb ingest bulk /path/to/folder --upload-concurrency 3 --retries 3 --json

Use an existing metadata map:

npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb ingest bulk /path/to/folder --metadata-map metadata-map.yaml --json

Use a metadata map saved at a specific path:

npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb ingest bulk /path/to/folder --metadata-map course-map.yaml --json

List uploadable collections:

npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb collections list --capability upload --json

Read a collection schema through the API:

npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb collections schema --collection-key course/thu_humanities --json

Check document status:

npx --yes --package "@tiangong-ai/cli@0.0.48" -- tiangong-ai kb ingest status <document-id> --json

Result Interpretation

• duplicate: true: the backend found an active existing document with the same dedupe identity. Tell the user the upload was treated as duplicate and show existingDocumentId when present.
• duplicate: false or missing: do not claim dedupe was checked unless the backend response says so.
• documentId: use this id for follow-up status checks.
• status: explain it as backend state. Terminal states are success/failure/deleted according to the API response; nonterminal states mean processing is still underway.
• jobId, statePath, requestId, idempotencyKey, rawUri: include them when present because they help support/debugging.
• metadata-map.yaml: explain it as a reusable layered rules file. It is not per-file metadata; CLI evaluates the same rule file for each file.

Safety Boundary

Never ask for or use:

• Supabase URL, anon key, service-role key, email/password, or session cookies
• NAS credentials or raw storage paths
• AWS, Pinecone, or OpenSearch admin credentials
• direct SQL/database queries to verify the current upload

The backend owns authorization, collection permission checks, duplicate detection, raw canonical write, document reservation, parse queueing, and status transitions. Read references/env.md only when environment setup or security boundaries matter.
