* feat: add PDF analysis tool with native provider support
New `pdf` tool for analyzing PDF documents with model-powered analysis.
Architecture:
- Native PDF path: sends raw PDF bytes directly to providers that support
inline document input (Anthropic via DocumentBlockParam, Google Gemini
via inlineData with application/pdf MIME type)
- Extraction fallback: for providers without native PDF support, extracts
text via pdfjs-dist and rasterizes pages to images via @napi-rs/canvas,
then sends through the standard vision/text completion path
Key features:
- Single PDF (`pdf` param) or multiple PDFs (`pdfs` array, up to 10)
- Page range selection (`pages` param, e.g. "1-5", "1,3,7-9")
- Model override (`model` param) and file size limits (`maxBytesMb`)
- Auto-detects provider capability and falls back gracefully
- Same security patterns as image tool (SSRF guards, sandbox support,
local path roots, workspace-only policy)
Config (agents.defaults):
- pdfModel: primary/fallbacks (defaults to imageModel, then session model)
- pdfMaxBytesMb: max PDF file size (default: 10)
- pdfMaxPages: max pages to process (default: 20)
Model catalog:
- Extended ModelInputType to include "document" alongside "text"/"image"
- Added modelSupportsDocument() capability check
Files:
- src/agents/tools/pdf-tool.ts - main tool factory
- src/agents/tools/pdf-tool.helpers.ts - helpers (page range, config, etc.)
- src/agents/tools/pdf-native-providers.ts - direct API calls for Anthropic/Google
- src/agents/tools/pdf-tool.test.ts - 43 tests covering all paths
- Modified: model-catalog.ts, openclaw-tools.ts, config schema/types/labels/help
* fix: prepare pdf tool for merge (#31319) (thanks @tyler6204)
