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 | $0.00048 | $0.01136 |
| Opus 5 | $0.00024 | $0.00568 |
| Sonnet 5 | $0.00010 | $0.00227 |
| Haiku 4.5 | $0.00005 | $0.00114 |
Grade A, and why
resize-images scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/as:resize-images — Image Resizer for Web, Social, and Print
Harness note: use
/as:<skill>on Claude Code and$<skill>on Codex. Resolve<skill-root>as the directory containing this loadedSKILL.mdand<plugin-root>as the plugin root that containsskills/, and use equivalent native tools when host tool names differ.
Resize project photos and renders for web publishing, social media, and print layouts. Always asks the user for the source folder before doing anything. Outputs resized copies into clearly named subfolders — originals are never modified.
Step 1: Ask for the source folder
Before doing anything else, ask:
"Which folder contains the images you'd like to resize?"
Wait for the user's response. Accept any valid path — absolute, relative, or with ~. Expand ~ to the user's home directory.
Then ask:
"Which outputs do you need? (choose one or more)
- Web — WebP at 1920px (hero), 1200px (standard), 400px (thumb)
- Social — center-cropped WebP: Instagram square (1080×1080), Instagram portrait (1080×1350), Twitter/X (1200×675), LinkedIn (1200×627)
- Slides — center-cropped JPEG: standard 4:3 (1024×768), widescreen 16:9 (1920×1080)
- Print — 300 DPI JPEG at ARCH A (9×12), ARCH B (12×18), ARCH C (18×24)
- All"
Step 2: Scan the folder
List supported files non-recursively: .jpg, .jpeg, .png, .tif, .tiff, and .webp. Report the count: "Found N image(s) in [folder]. Ready to resize."
If the folder is empty or contains no supported images, tell the user and stop.
Step 3: Check for Pillow
Confirm Pillow is available:
python3 -c "import PIL; print('ok')" 2>/dev/null || echo "missing"
If missing, tell the user:
"Pillow isn't installed. Run
pip install Pillowthen try again."
Stop if Pillow is unavailable.
Step 4: Resize images
Run the bundled processor once, passing the source folder and selected modes:
python3 "<plugin-root>/skills/resize-images/scripts/resize_images.py" "<folder>" web social slides print
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.
