Primary Exam (PEX) Knowledge Graph CLI for CICM/ANZCA exam preparation. Semantic search over Learning Outcomes, SAQs, concepts, and topics. Use for exam study, prerequisite chains, learning paths, and higher-order concept connections.
Knowledge graph-based exam preparation for CICM/ANZCA Primary Exams. Provides semantic search, prerequisite chains, learning paths, and LLM-inferred higher-order connections.
# Semantic search for Learning Outcomes
pex search "shock physiology" --limit 10
# Show prerequisites for a topic
pex prereq "LO-cardio-001"
# Generate learning path for a concept
pex path "cardiovascular physiology"
# Find concepts that refine/specialize another
pex refine "hemodynamics"
# Graph statistics
pex stats
# Search Learning Outcomes (default)
pex search "septic shock management" --limit 5
# Search specific node types
pex search "dobutamine" --label Concept
pex search "cardiovascular" --label Topic
pex search "shock" --label SAQ
# Show prerequisites for a Learning Outcome
pex prereq "LO-001"
# Get specific node by ID
pex get "LO-001"
# Generate learning path for a topic
pex path "renal physiology"
# Find LOs that refine/specialize another
pex refine "fluid balance"
# Find concepts implied by this concept
pex imply "cellular respiration"
# Ingest from markdown files (LOs, SAQs)
pex ingest-md /path/to/markdown/
# Phase 6 LLM inference for higher-order connections
pex phase6-infer --model claude-3-5-sonnet
# Clear graph
pex clear

The PEX CLI integrates with the grounding-router as the Σₚₑₓ primitive:
Σₚₑₓ — Primary Exam Source
Sub-Primitives:
| Σₚ₁ | LO Search | 0.95 | pex search "topic" --label LearningOutcome |
| Σₚ₂ | SAQ Search | 0.90 | pex search "topic" --label SAQ |
| Σₚ₃ | Prerequisites| 0.85 | pex prereq "LO-id" |
| Σₚ₄ | Learning Path| 0.80 | pex path "concept" |
| Service | Port | Required |
