PDF Validation

Validate PDF & operation outputs (pdf-validation)

Validate PDF & operation outputs

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

Prove an operation actually worked before trusting it.

Operations

• openable
• page count
• renderability
• text coverage
• redaction leak check
• output sanity

Engine (what actually executes this)

universal_pdf/core.validation + per-module Outcome.checks

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: uniform ValidationCheck
• 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)

named checks with pass/fail
