logicprobe-uml SKILL.md skillA
logicprobe-uml from amethystluna/logicprobe is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add amethystluna/logicprobe/logicprobe-uml@git:20261018.c165e70Pins git:20261018.c165e70 in mdr.lock. Pin the fingerprint instead.

Use when drawing a code flow as UML or auditing a diagram someone drew: parse a hand-drawn state or activity diagram, render a model, and check round-trip fidelity (dead ends, unreachable states, label drift). Component, class and ER diagrams are refused, not modelled. Doctrine and behavioural verification: the logicprobe skill.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Logic Probe — UML Modelling > **Successor: `dsh-model-everything`.** Its counterpart skill is `model-everything-uml`, which draws and reads more diagram families. Load that one when both plugins are installed; this skill stays accurate for `logicprobe_uml`. A diagram is a model, and a model can be wrong. A tidy flow chart is not evidence about the code, and a diagram that disagrees with its own model is worse than no diagram, because a reader will believe it. This skill covers the diagram half of the Logic Probe toolbox. The claim-verification doctrine it inherits — enumerate verifiable claims, cite `file:line`, read `verdict` and never `ok` — lives in the `logicprobe` skill; load that one when the task is to verify behaviour rather than to draw or audit a diagram. ## When This Skill Applies | The task involves… | What it does | |---|---| | Modelling a code flow as a state, activity or sequence diagram | `logicprobe_uml action=render`: model to diagram source, with a citation per state, event, guard and action | | Reading a hand-drawn diagram back into a model | `action=parse`: Mermaid or PlantUML state/activity text into a LogicModelV1 that `logicprobe_verify` can check | …

How to install
mdr add amethystluna/logicprobe/logicprobe-uml@sha256:c8cf6af7e0ea1244The line at the top of this page pins the label git:20261018.c165e70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
