Tiangong KB Edu Search

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

Prerequisites

• The wrapper defaults to the exact reviewed entrypoint npx --yes --package "@tiangong-ai/cli@0.0.62" -- tiangong-ai; users do not need a preinstalled CLI. Set TIANGONG_AI_CLI or TIANGONG_AI_CLI_BIN only to override the CLI entrypoint intentionally.
• Set TIANGONG_EDU_APIKEY or TIANGONG_AI_APIKEY. Credentials are never accepted in wrapper JSON, request files, URLs, or CLI arguments.
• 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. It must be an owner-only regular non-symlink file (chmod 600), and only documented Tiangong variables are loaded. Existing process variables win.
• 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/edu_search.sh '{
  "query": "education policy curriculum reform",
  "top_k": 5
}'

The script calls:

npx --yes --package "@tiangong-ai/cli@0.0.62" -- tiangong-ai education search --query <query> --sources edu --json

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

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

Raw Payload Filters

Wrapper JSON can include inline raw edu_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": "water treatment filter backwashing",
  "filter": {
    "course": ["水处理工程"]
  },
  "topK": 5,
  "extK": 1
}

• Normal search currently uses only filter.course to narrow retrieval to one or more course names; other metadata fields are not applied in the retrieval path.
• edu_search has a separate {"action":"list_filter_options"} mode for discovering metadata values. In that mode, fields may include course, type, file_type, language, chapter_number, and name; optional filter narrows the listed options.
• topK, extK: raw edge-function names for result count and adjacent chunk expansion.
• datefilter and getMeta are not supported by edu_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, action, fields, topK, extK: optional inline raw payload fields for edu_search.
• sources: optional compatibility field; only edu or default is accepted.
• dry_run: true to return the exact request plan with masked credentials.
• api_base_url, edu_url, region, timeout as non-secret routing values.
• top_k, ext_k: only used in query mode.
