The instruction itself

4 sections, as written by the author

$ca-decompose — greenfield populate

Stands up project state for a greenfield project — one with no meaningful source code yet. A senior-architect persona drives a six-layer interview eliciting purpose, scope, primary users, domain vocabulary, and architectural constraints, persisting each layer to disk so a context reset loses nothing, then writes the surviving .codearbiter/ doc set and locks the project initialized. No arguments — the skill interviews the user (a handoff summary may be supplied freely during the interview).

The only permitted path to populate .codearbiter/ when no meaningful source exists. For an existing codebase, use $ca-create-context.

Routes to

The decompose skill (${CLAUDE_PLUGIN_ROOT}/routines/decompose/SKILL.md) — six gated phases:

pre-flight, persona adoption, layered interview, synthesis, population, lock. The skill is canonical

for the layers and their gates.

When NOT to use

Project already initialized ( in CONTEXT.md) → $ca-status.
Existing codebase with source present → $ca-create-context.
.codearbiter/ not yet scaffolded → $ca-init first.
Update one doc → edit <project-root>/.codearbiter/ directly or use $ca-feature.

Hard gate

BLOCK if  is already present in CONTEXT.md. BLOCK if meaningful source is

detected (route to $ca-create-context). BLOCK if any [CONFIRM-NN] exits synthesis unresolved and

undeferred. MUST NOT write  until every required doc is present and non-empty.

Excalidraw Diagram Generator

by github

vendor ×3

Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.

Build and distribute Expo development clients locally or via TestFlight

Use when you have a written implementation plan to execute in a separate session with review checkpoints

Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
