PDF Annotate

Add annotations (pdf-annotate)

Add annotations

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

Annotate pages with standard markups and notes.

Operations

• highlight
• underline
• strikeout
• text note
• free text
• square/circle
• line/arrow
• link
• preserve existing annotations

Engine (what actually executes this)

universal_pdf/core.annotate:add_annotations

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: PyMuPDF annotation API
• 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)
