Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00036 | $0.00545 |
| Opus 5 | $0.00018 | $0.00272 |
| Sonnet 5 | $0.00007 | $0.00109 |
| Haiku 4.5 | $0.00004 | $0.00055 |
Grade A, and why
user-assets 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 4d 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.
What it actually says
User-Pasted Image Integration
When the user pastes images, determine what to do with each one and integrate it into the project.
Step 1: Determine Intent
Read the user's message and classify each image:
| Intent | Signals | Action |
|---|---|---|
| Design reference | "make it look like this", "match this style", "here's a mockup" | Analyze visually to guide your code. Do NOT copy into the project. |
| App icon | "use this as the icon", "app icon", "this is the logo" | Copy to AppIcon.appiconset/, resize to platform size. See references/app-icon-installation. |
| In-app image | "add this image", "use this in the app", "background image", "splash" | Copy to Assets.xcassets/ as a named image set. See references/image-asset-integration. |
| Ambiguous | No clear signal | Default: treat as an in-app image asset. |
Step 2: Verify the Source Image
# Confirm file exists and get dimensions
sips -g pixelWidth -g pixelHeight /path/to/pasted/image.png
Step 3: Integrate
Follow the appropriate reference:
- App icon → references/app-icon-installation
- In-app image → references/image-asset-integration
Key Rules
- Always copy, never reference temp paths — pasted images live in temp directories that are cleaned up. Use
cpto copy into the project. - Use
cp, notmv— preserve the original in case the session needs it again. - Use
sipsfor all image operations — always available on macOS. No ImageMagick needed. - Name files from context — use meaningful names like
logo.png,hero-background.png, not the temp filename. - Reference in code correctly —
Image("name")for asset catalog images (no extension).Bundle.main.url(forResource:)for raw bundle resources.

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
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.

user-assets is a skill published in the GitHub repository Abdullah4AI/apple-developer-toolkit (10 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 545 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
