文档处理实战：启用 PDF 工具做多页文档提取与问答

问题/场景：长 PDF 需要快速提取结构化信息并交给模型分析。前置条件：模型支持 Anthropic/Google 原生 PDF 或配置了提取回退；并设置 `agents.defaults.pdfModel`、`pdfMaxBytesMb`、`pdfMaxPages`。实施步骤：配置 PDF 模型与阈值 → 上传样例文档 → 执行分析提示词 → 根据页数/体积调优。关键配置：`agents.defaults.pdfModel`、`pdfMaxBytesMb`、`pdfMaxPages`。验证方法：超限文档被正确拦截，合规文档能稳定产出引用明确的摘要。风险与边界：扫描件 OCR 质量受源文件影响（需验证）。来源归因：v2026.3.2-beta.1 Release Notes。

Prerequisites

PDF tool is available in your OpenClaw build (v2026.3.2-beta.1+).
A compatible provider/model is configured for PDF analysis.

Steps

Set default PDF model and conservative page/size limits in config.
Run a small known PDF through the tool to validate extraction quality.
Prompt for structured output (sections, key facts, cited page ranges).
Increase `pdfMaxPages` gradually and monitor latency/token impact.
Document provider-specific fallback behavior for unsupported PDFs.

Commands

openclaw gateway status

openclaw gateway restart

Verify

Expected sections are extracted with page-level traceability, and oversized PDFs are rejected with clear errors.

Caveats

Scanned or image-heavy PDFs may require additional OCR quality checks（需验证）.
Large-page documents can increase token cost quickly; keep strict limits by default.
