Security note

Pi packages can execute code and influence agent behavior. Review the source before installing third-party packages.

README

pi-parse-china-standard

Pi extension that downloads an official Chinese national-standard PDF from the SAMR open-standard site, parses it with MinerU, and returns the generated Markdown path to the agent.

Install

pi install npm:pi-parse-china-standard@0.1.0

The package includes @playwright/cli. Python 3 must be available as python on Windows or python3 on other platforms.

Configure MinerU

Copy config/mineru.example.json to either:

  • <workspace>/.pi/china-standard/mineru.json
  • another path selected by MINERU_CONFIG

Keep credentials in an environment variable:

{
  "mode": "cloud",
  "submit_endpoint": "https://mineru.net/api/v4/file-urls/batch",
  "result_endpoint_template": "https://mineru.net/api/v4/extract-results/batch/{batch_id}",
  "token": "env:MINERU_TOKEN",
  "request_timeout_seconds": 60,
  "parse_timeout_seconds": 1800,
  "poll_interval_seconds": 5
}

Tool

The package registers china_standard_parse with one argument:

{
  "standard_number": "GB/T 35697-2026"
}

The agent receives only the absolute path to full.md. The original PDF, Markdown, JSON, DOCX, HTML, LaTeX, images, MinerU ZIP, and cache manifest remain together under:

<workspace>/china-standard-output/<normalized-standard-number>/

Local cache

The workflow is lazy and local-only:

  1. Reuse source.pdf only when its PDF signature, standard number, and SHA-256 match cache-manifest.json.
  2. Reuse parsed files only when the source SHA-256, parsing-profile SHA-256, and every recorded output file match the manifest.
  3. If only parsing is stale or incomplete, reuse source.pdf and call MinerU again.
  4. If the PDF cache is invalid, download a verified replacement before changing the cached source.

Database-backed caching is intentionally deferred to docs/future-plan.md.
