compose-capture-to-share-image

compose-capture-to-share-image is a skill for Claude Code from maxrave-dev/kotlin-footguns. It costs 138 tokens per session (2,029 once invoked), scanned A, original, GPL-3.0.

A coding guide for turning a Compose UI component into a shareable or savable picture. It covers rendering the component off-screen into an ImageBitmap, preparing artwork beforehand, and limiting the output width.

In plain words
What is it for?
Use it when adding a button that captures a Compose component as an image for saving or sharing, especially when the artwork must be resolved first or the output needs a width limit.
Why use it?
It addresses the gap between something displayed in the interface and an actual image file that a user can save or share. It also handles work that should happen before the capture action.

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.

Security

Grade A, and why

compose-capture-to-share-image 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 11d 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.
