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.

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 | $0.00135 | $0.01549 |
| Opus 5 | $0.00068 | $0.00775 |
| Sonnet 5 | $0.00027 | $0.00310 |
| Haiku 4.5 | $0.00014 | $0.00155 |
Grade A, and why
solo-apple-app-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 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.
How it starts
The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
apple-app-icon — the icon as a build artefact, not a drawing
On iOS 26 an app icon is no longer a flattened PNG: it is a small bundle of layers the system lights, tints and renders as Liquid Glass. Icon Composer draws them by hand; this skill generates the same document from the brand artwork, so the icon is rebuilt when the brand changes rather than redrawn from memory.
Reach for it when the icon and the app disagree — different mark, different gradient, or nine PNGs whose source nobody can find.
Workflow
1. Find the real artwork before drawing anything
Two attempts went the wrong way on one project before the file turned up: rebuilding the mark from the app's own button geometry (beautiful, and a different mark), then tracing it off a 1024 PNG by measuring pixels (the right mark, at second-hand accuracy).
find ~ -maxdepth 7 \( -iname "*logo*" -o -iname "*icon*" \) \
\( -iname "*.svg" -o -iname "*.ai" -o -iname "*.sketch" \) 2>/dev/null
mdfind -name "logo" # useless if Spotlight is off — check `mdutil -s /`
Look in abandoned web projects and old zips; a Figma export usually survives
somewhere even when the designer's archive link is dead. What you want is one
artboard, already composed: the mark on its tile, with the background
gradient in a <linearGradient>. That file is the source of truth — copy it
into the repo (Resources/logo-source.svg) so the icon has a provenance.
2. Generate
python3 "${SKILL_DIR}/scripts/make_icon.py" \
--source Resources/logo-source.svg \
--icon Resources/App.icon --render
It reads the stops, the viewBox and the paths out of the artwork, splits the
paths into layers, writes icon.json, and exports all six appearances through
ictool. Nothing is retyped — a hex copied into a script is a second source of
truth that drifts on the next export.
3. Look at all six, not at one
Default · Dark · TintedLight · TintedDark · ClearLight · ClearDark
The dark and tinted appearances are where a mark falls apart: the system re-colours the layers, and thin white lines with dark gaps — the shape of most marks — are exactly what a translucent treatment fills in. Rendering is three seconds; guessing costs a release.
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.

solo-apple-app-icon is a skill published in the GitHub repository fortunto2/solo-factory (18 stars, last pushed today), licensed MIT. It adds 135 tokens to every session and 1,549 once invoked, about $0.0007 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 2026-08-30.
