aminer-pdf-ocr

aminer-pdf-ocr is a command for Claude Code from CanXiangCC/aminer-open-skill. It costs 0 tokens per session (841 once invoked), scanned A, original, MIT.

A tool that reads text from a PDF or image and extracts structured experiment details, such as methods, datasets, metrics, and results. OCR means recognising text in scanned pages or images so it can be processed.

In plain words
What is it for?
Use it to process an eligible PDF or image, run OCR, and extract information about a study’s methods, datasets, evaluation measures, and results.
Why use it?
Important experimental information may be trapped in scanned documents or difficult-to-parse PDFs. Turning it into structured fields makes those details easier to review and compare.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aminer-pdf-ocr scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

$ARGUMENTS

Language Routing / 语言路由

  • If $ARGUMENTS or the conversation is mainly Chinese, follow 中文命令流程 and read ${CLAUDE_PLUGIN_ROOT}/SKILL.zh.md.
  • Otherwise follow English Command Flow and read ${CLAUDE_PLUGIN_ROOT}/SKILL.md.
  • Parameter names stay English: input, output-dir, ocr-only, no-save-images, output.
  • JSON keys stay English (engine, status, artifacts, counts, etc.).
  • 如果 $ARGUMENTS 或对话主要是中文，使用 中文命令流程。
  • 否则使用 English Command Flow。

English Command Flow

1. Pre-flight

  1. Check that AMINER_API_KEY exists without printing its value. If missing, stop and send the user to https://open.aminer.cn/open/board?tab=control. OPEN_PLATFORM_TOKEN is a deprecated fallback only.
  2. Check that requests and pypdf are installed.
  3. Confirm the user supplied a local PDF or an HTTP(S) URL. The open API accepts only unencrypted PDFs with 1-30 pages and size <= 10 MiB.

2. Run

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/ocr.py" --input "<input>"

Pass --output-dir, --request-timeout, --poll-timeout, --max-upload-attempts, --no-save-images, or --output only when requested. Do not pass the removed local-parser options (custom base URL, backend, page ranges, formula, or table flags).

3. Extract Experiments

Unless ocr-only: yes, read the complete <output-dir>/result.md, read references/experiment_prompt.md, write one JSON object to <output-dir>/experiments.json, and paste that same complete JSON into the reply. Do not add justification fields or invent facts.

中文命令流程

1. 执行前检查

  1. 检查 AMINER_API_KEY 是否存在，禁止回显值；缺失则停止，并引导用户前往 https://open.aminer.cn/open/board?tab=control。`OPEN_PLATFORM_TOKEN` 仅作兼容回退。
  2. 检查 requests 和 pypdf 依赖。
  3. 确认用户提供本地 PDF 或 HTTP(S) URL。开放接口只接受未加密、1–30 页且不超过 10 MiB 的 PDF。

2. 运行

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/ocr.py" --input "<input>"
