Convert SVG files to Android VectorDrawable XML using the svg2vector CLI. Auto-load when the user wants to convert SVG icons to Android, batch-process a folder of SVGs, integrate Figma exports into an Android project, or replace Android Studio's GUI-only Vector Asset Studio with an agent-callable workflow.From its SKILL.md

svg2vector skill

When the user wants to turn SVG file(s) into Android VectorDrawable XML, use the svg2vector CLI. It wraps Android Studio's official Svg2Vector algorithm (com.android.tools:sdk-common) and produces output byte-identical to Vector Asset Studio's GUI — but as a fast (~8ms cold start) headless CLI you can call from a script or agent.

Prerequisite check

Before the first invocation, run command -v svg2vector. If missing, ask the user to confirm and run:

curl -fsSL https://raw.githubusercontent.com/HelloVass/svg2vector-skills/main/install.sh | sh

This installs ~/.local/bin/svg2vector (auto-detects macOS arm64 / x86_64 / Linux x86_64). User must have ~/.local/bin in PATH.

CLI surface

svg2vector convert <input.svg> [-o <output.xml>]
svg2vector batch <input-dir> <output-dir> [-r|--recursive]

convert writes one XML next to the input (or wherever -o points). batch walks a directory; -r recurses subdirectories preserving structure.

Exit code contract — this is the API

Code	Meaning	What to do
`0`	clean success	surface `wrote ...` to user
`1`	fatal (cannot convert / I/O failure)	read stderr, surface error
`2`	success with warnings (XML still written, some SVG features dropped)	surface dropped features so user knows what's missing
`3`	bad CLI arguments	fix invocation, retry

In batch mode, the process exits with the worst per-file code seen.

Streams contract

stdout: only success messages (wrote ..., batch summary)
stderr: errors and "feature X is not supported" warnings

Capture them independently:

out=$(svg2vector convert input.svg -o output.xml 2>warnings.log); rc=$?

Known input gotchas

Figma dev mode SVGs (URLs like localhost:3845/assets/<hash>.svg) embed var(--token, color) CSS variables. Svg2Vector doesn't resolve them — output has unusable color attributes. Preprocess: sed -E 's/var\(--[^,]+,\s*([^)]+)\)/\1/g' in.svg > clean.svg. Or have the user export from Figma's Export panel (literal colors, no preprocessing).
<text> / <filter> / <mask> / <pattern> / <image> / external <use> / CSS @import are silently dropped — exit code 2 with stderr warnings. For Figma drop-shadow filters specifically, the Android-side replacement is android:elevation on the View, not the drawable.
