What is add-material-icon?

A procedure for downloading a Material Design icon and turning its SVG image into a Kotlin Compose icon.

It helps developers add Material icons to the Aktual Compose icon library, including classic or newer Material icon variants.

It removes the repetitive work of finding the correct icon source and converting it into code the app can display.

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high YARA Match · line 3
YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).

Fix: Remove offensive tool references and exploit code. Legitimate agent skills should not contain penetration testing tools, exploit frameworks, or reconnaissance utilities.

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	$0.00037	$0.01667
Opus 5	$0.00018	$0.00834
Sonnet 5	$0.00007	$0.00333
Haiku 4.5	$0.00004	$0.00167

Security

Grade A, and why

add-material-icon 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 7d 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.

Add a Material Design icon to the aktual-core/icons module by fetching its SVG source and converting it to a Kotlin ImageVector.

Do NOT ask clarifying questions — just execute.

Arguments

$ARGUMENTS should contain the icon name in either snake_case or PascalCase (e.g., calendar_today or CalendarToday)
If --classic is included, fetch from classic Material Icons (24x24) instead of Material Symbols
If --material is included, use MaterialIcons as the receiver instead of AktualIcons

Step-by-Step Process

1. Determine source and fetch SVG

Material Symbols (default, 960x960):

Fetch the filled variant SVG directly from the Google Fonts CDN:

https://fonts.gstatic.com/s/i/short-term/release/materialsymbolsoutlined/{snake_case_name}/fill1/24px.svg

The fill1 path segment selects the filled variant. The response is a plain SVG file (not base64).

Classic Material Icons (with --classic, 24x24):

The source repo is: https://android.googlesource.com/platform/frameworks/support/+/1de65587b7e999a38df120bd8827c3594974864d/compose/material/material/icons/generator/raw-icons/filled/

Convert the PascalCase icon name to snake_case for the filename (e.g., AccountCircle → account_circle).

Fetch the SVG using WebFetch:

https://android.googlesource.com/platform/frameworks/support/+/1de65587b7e999a38df120bd8827c3594974864d/compose/material/material/icons/generator/raw-icons/filled/{snake_case_name}.xml?format=TEXT

The response is base64 encoded. Decode it to get the Android Vector Drawable XML.

2. Parse the SVG/Vector Drawable

From the Android Vector Drawable XML (classic), extract:

android:viewportWidth and android:viewportHeight (typically 24)
android:pathData from each <path> element

From an SVG (symbols), extract:

The viewBox attribute (typically 0 -960 960 960)
The d attribute from each <path> element

3. Convert path data to Kotlin

Convert SVG/Android path commands to Kotlin PathBuilder calls:

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.
