Tiangong KB Textbook Search

Use this skill for Tiangong textbook-source retrieval. It is intentionally single-source: always search textbook, never all, course, or edu.

Prerequisites

• The wrapper defaults to npx @tiangong-ai/cli@0.0.19; users do not need a preinstalled CLI. Set TIANGONG_AI_CLI or TIANGONG_AI_CLI_BIN only to override the CLI entrypoint.
• Set the authentication environment variables expected by tiangong-ai.
• When request_file / input_file is provided, the wrapper loads .env from that file's directory by default. env_file can point to a different dotenv file. Loaded dotenv values only fill unset environment variables; explicit JSON fields such as api_key, textbook_api_key, and api_base_url are passed as CLI flags and take precedence.
• Optionally set TIANGONG_AI_API_BASE_URL; the CLI accepts a Supabase project root, /functions/v1, or /rest/v1 and derives Functions URLs.

Search

For normal searches, pass a query:

./scripts/textbook_search.sh '{
  "query": "activated sludge process principles",
  "top_k": 5
}'

The script calls:

npx @tiangong-ai/cli@0.0.19 education search --query <query> --sources textbook --json

For exact edge-function payloads, provide request_file or input_file:

./scripts/textbook_search.sh '{
  "request_file": "./textbook-request.json",
  "dry_run": true
}'

Raw Payload Filters

Wrapper JSON can include inline raw textbook_search fields; the wrapper will forward them through the CLI --input path. The same payload can also be put in request_file / input_file:

{
  "query": "如何减排二氧化碳？",
  "filter": {
    "isbn_number": ["9787030641274"]
  },
  "datefilter": {
    "publication_date": { "gte": 1262304000 }
  },
  "topK": 5,
  "extK": 1
}

• filter: metadata term filters, shaped as { "field": ["value"] }.
• datefilter: numeric range filters, shaped as { "field": { "gte"?: number, "lte"?: number } }, for indexed numeric/date metadata fields.
• topK, extK: raw edge-function names for result count and adjacent chunk expansion.
• getMeta is not supported by textbook_search.

Input Fields

• query or input: convenience query text.
• request_file or input_file: JSON body forwarded unchanged.
• env_file: optional dotenv file. Without it, request_file / input_file causes the wrapper to load .env from that file's directory.
• filter, datefilter, topK, extK: optional inline raw payload fields for textbook search.
• sources: optional compatibility field; only textbook or default is accepted.
• dry_run: true to return the exact request plan with masked credentials.
• api_base_url, api_key, textbook_api_key.
• textbook_url, region, timeout.
• top_k, ext_k: only used in query mode.
