PDF Diff

Page/text diff report (pdf-diff)

Page/text diff report

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

Get a readable list of added/removed/modified content between two versions.

Operations

• revision diff
• unified text change sample
• human-readable report

Engine (what actually executes this)

universal_pdf/core.compare:compare_pdfs + text_report

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: difflib
• Fallback: —

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)
