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

image-upload 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/upload_image.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

image-upload

Upload any image to your own GitHub repo and get back three URL formats — jsDelivr CDN (fast, public), GitHub raw, and Markdown — ready to paste into documentation, blog posts, or chats.

Prerequisites (one-time setup)

  1. A GitHub repo for images. Create one yourself (public preferred so jsDelivr CDN serves it), e.g. your-username/images.
  2. gh CLI installed and authenticated: 
    brew install gh
gh auth login
  3. jq installed (for JSON serialization): 
    brew install jq
  4. pngpaste (only for clipboard screenshot mode): 
    brew install pngpaste
  5. Set environment variables in your shell profile (~/.zshrc or ~/.bashrc): 
    export IMAGE_HOST_REPO="your-username/images"   # required
export IMAGE_HOST_BRANCH="master"               # optional, default: master
export IMAGE_HOST_BASE_DIR="uploads"            # optional, default: uploads
    Reload your shell or source ~/.zshrc.

Per-invocation overrides via --repo, --branch, --base-dir flags also work.

Usage

Upload one or more files:

bash "${CLAUDE_SKILL_DIR}/scripts/upload_image.sh" path/to/image.png
bash "${CLAUDE_SKILL_DIR}/scripts/upload_image.sh" file1.jpg file2.png file3.webp

Upload from clipboard (most recent screenshot, or files copied in Finder):

bash "${CLAUDE_SKILL_DIR}/scripts/upload_image.sh" --clipboard

Auto-copy a specific URL format to system clipboard:

bash "${CLAUDE_SKILL_DIR}/scripts/upload_image.sh" --copy markdown file.png
bash "${CLAUDE_SKILL_DIR}/scripts/upload_image.sh" --copy jsdelivr --clipboard
bash "${CLAUDE_SKILL_DIR}/scripts/upload_image.sh" --copy raw file1.jpg file2.jpg

--copy values: jsdelivr (CDN), raw (GitHub raw), markdown (![](url) format).

How it works

  • Files are renamed to timestamp format: 20260513-143025.jpg. Batch uploads add an index: -1, -2, etc.
  • Each image is committed to <base-dir>/YYYY/MM/<name>.<ext> in your repo.
  • Filename conflicts auto-resolve with a numeric suffix.
  • Multiple files upload in parallel (with retry on transient 409s from branch HEAD races).
  • For each image, three URLs are printed: jsDelivr CDN, GitHub raw, and Markdown.

Files

What ships with it

1 file 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.

Changes

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.
