PDF Vision

Visual interpretation of pages/figures (pdf-vision)

Visual interpretation of pages/figures

Part of the Universal PDF Management & Creation Skill Repository. Category: PDF Management. Every skill is individually callable (INDIVIDUAL MODE) and may also be invoked automatically by the orchestrator (SYSTEM MODE).

When to use

Only invoke vision when text/OCR is insufficient to answer the request.

Operations

• describe a rendered page
• interpret charts/graphs/diagrams/forms
• graceful fallback to text/OCR when no vision model

Engine (what actually executes this)

universal_pdf/core.vision:describe_page (register a provider first)

All heavy lifting is done on disk / one page at a time by the shared engine — never by loading the document into an LLM context.

Tools & graceful degradation

• Preferred tool: pluggable vision provider (agent/LLM)
• Fallback: text/OCR extraction

If the preferred backend is unavailable the skill transparently uses the fallback or reports a documented limitation. It never reports success when an operation did not actually happen.

Validation (this skill attaches checks to its Outcome)
