A medical-imaging command that evaluates changes where spinal discs meet the vertebrae on MRI. It classifies Modic endplate changes, grades disc wear with the Pfirrmann system, and checks for spinal-cord compression in the neck and chest regions.

Use it for full or lumbar-focused assessment of Modic changes and disc degeneration, with cord-compression screening for cervical and thoracic scans.

It turns several MRI findings into named classifications, making disc and endplate assessment more systematic. It also identifies when both T1- and T2-weighted MRI scans are required.

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	$0.01216
Opus 5	$0.00000	$0.00608
Sonnet 5	$0.00000	$0.00243

Security

Grade A, and why

modic-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 11d 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.

/modic-eval - Modic Changes & Disc Degeneration Assessment

MRI evaluation of Modic endplate changes and disc degeneration.

Description

Classifies Modic endplate changes (Types 0-III) and Pfirrmann disc degeneration grades using T1 and T2-weighted MRI sequences. Includes cord compression screening for cervical and thoracic regions.

Usage

/modic-eval                 # Full Modic + Pfirrmann assessment
/modic-eval lumbar          # Focus on lumbar region

Instructions

When the user invokes this command:

1. Verify MRI data

Call list_scene_nodes(). This protocol requires T1 and T2 weighted MRI volumes.

If missing:

Modic evaluation requires both T1 and T2 weighted MRI sequences.
Please load the appropriate DICOM series.

Currently loaded:
  T1: [found/missing]
  T2: [found/missing]

2. Segment spine (MRI mode)

segment_spine(input_node_id=<t2_volume_id>, region=<region>)

3. Classify Modic changes

classify_modic_changes(
    t1_volume_id=<t1_id>,
    t2_volume_id=<t2_id>,
    segmentation_node_id=<seg_id>
)

Modic classification:

Type 0: Normal endplate signal
Type I: T1 hypointense + T2 hyperintense (edema/inflammation — ACTIVE, symptomatic)
Type II: T1 hyperintense + T2 iso/hyperintense (fatty replacement — stable)
Type III: T1 hypointense + T2 hypointense (sclerosis)
Mixed I/II: Transitional pattern

4. Assess disc degeneration (Pfirrmann)

assess_disc_degeneration_mri(
    t2_volume_id=<t2_id>,
    segmentation_node_id=<seg_id>
)

Pfirrmann grading (T2-weighted):

Grade I: Homogeneous, hyperintense, normal height
Grade II: Heterogeneous with horizontal band, hyperintense, normal height
Grade III: Heterogeneous gray, intermediate signal, normal to slight height loss
Grade IV: Heterogeneous dark gray, hypo to intermediate signal, moderate height loss
Grade V: Heterogeneous black, hypointense, collapsed

What this file has done since we first saw it

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.

modic-eval is a command published in the GitHub repository zhangreling02-ai/3dslicer-claude-bridge (0 stars, last pushed 6mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,216 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
