diagram SKILL.md skillA
diagram from yeachan-heo/oh-my-claudecode is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add yeachan-heo/oh-my-claudecode/diagram@git:20260912.85ca3bcPins git:20260912.85ca3bc in mdr.lock. Pin the fingerprint instead.

Use the smallest visual when prose must carry structure—control flow, call depth, module ownership, or change shape: pseudocode, call tree, component/file tree, Mermaid diagram, or diff. Skip it when prose already answers the question.
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
**Diagrams are load-bearing, not decoration.** Reach for one only when prose forces the reader to hold a whole shape in their head at once — then pick the smallest view that lets them see the shape instead of reconstructing it from sentences. Everything here renders in the conversation as text blocks or Mermaid; at most one artifact file is ever written.
## The vocabulary
Pick one view; two at most. More is noise.
**Pseudocode** — logic without language noise. Reduces a decision to its branching shape:
```text
on(request)
if state file locked by another writer
queue and return pending
acquire lock
write
release
```
**Call tree** — runtime control flow. Depth shows who owns the flow; annotate where the interesting edge is:
```text
acquireStateFileLockSync()
resolveLockPath()
openExclusive()
writePid()
```
**Component tree** — UI or module structure, with the boundaries that matter annotated inline:
```tsx
<SettingsPage> (src/routes/settings)
<SessionList> (owns its fetches)
<DangerZone>
<ConfirmButton> (disabled until typed confirmation)
```
**File tree** — where responsibility lives; keep it shallow, one annotation per directory:
```text
src/
…Read the whole file at its exact version.
How to install
mdr add yeachan-heo/oh-my-claudecode/diagram@sha256:13e51a5ccc2e4e2fThe line at the top of this page pins the label git:20260912.85ca3bc, 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.
