What is fracture-eval?

A command for evaluating possible vertebral fractures in CT scans or X-ray images. It detects and classifies fractures, and can also screen for osteoporosis and spinal-canal narrowing.

Use it to inspect available scans, select a CT or X-ray workflow, segment the spine, detect fractures, classify them, and assess osteoporosis or canal compromise.

It organizes the imaging workflow and applies named medical classification systems instead of requiring each step to be run manually.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00988
Opus 5	$0.00000	$0.00494
Sonnet 5	$0.00000	$0.00198

Security

Grade A, and why

fracture-eval scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/fracture-eval - Vertebral Fracture Evaluation

Automated vertebral fracture detection and classification.

Description

Detects and classifies vertebral fractures using CT and/or X-ray data. Applies AO Spine, Denis, and Genant classification systems. Includes osteoporosis screening and canal compromise assessment.

Usage

/fracture-eval              # Auto-detect modality and evaluate
/fracture-eval ct           # CT-specific pipeline
/fracture-eval xray         # X-ray-specific pipeline

Instructions

When the user invokes this command:

1. Inventory available data

Call list_scene_nodes() to identify CT volumes, X-ray volumes, and existing segmentations.

Determine modality:

If $ARGUMENTS specifies "ct" or "xray", use that pipeline
If not specified, auto-detect from loaded volumes
If both CT and X-ray available, run CT pipeline (more comprehensive)

2. CT Pipeline

2a. Segment spine

segment_spine(input_node_id=<ct_id>)

2b. Detect fractures

detect_vertebral_fractures_ct(
    volume_node_id=<ct_id>,
    segmentation_node_id=<seg_id>,
    classification_system="all"
)

2c. Osteoporosis screening

assess_osteoporosis_ct(
    volume_node_id=<ct_id>,
    segmentation_node_id=<seg_id>,
    levels=["L1"]
)

2d. Canal assessment (if burst fracture detected)

If any fracture has AO type A3, A4, B, or C (posterior wall or canal involvement):

measure_spinal_canal_ct(
    volume_node_id=<ct_id>,
    segmentation_node_id=<seg_id>,
    levels=<fractured_levels>
)

2e. Screenshots

capture_screenshot(view_type="sagittal")   # Sagittal at fracture level
capture_screenshot(view_type="axial")      # Axial at fracture level

2f. CT Report

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
