heic-to-jpeg-bundle

heic-to-jpeg-bundle is a skill for Claude Code from terrylica/cc-skills. It costs 137 tokens per session (1,934 once invoked), scanned A, original, MIT.

A macOS workflow that converts iPhone HEIC photos into JPEG files and packages them as a browsable gallery with an optional password-protected ZIP file. HEIC is an image format that many Windows systems and older business tools cannot open.

In plain words
What is it for?
Use it to convert a folder of HEIC images, make a shareable thumbnail gallery, and prepare a bulk-download ZIP for a static website.
Why use it?
It lets recipients and software that require JPEG files view or import the photos without relying on online conversion services.

    Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.
    Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files. Treat skill files as read-only at runtime.

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

heic-to-jpeg-bundle 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/make-bundle.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.

heic-to-jpeg-bundle

Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.

Turn a folder of HEIC (or any sips-readable) images into a share-ready JPEG bundle: a self-contained gallery page plus an optional password-protected ZIP. Everything runs through macOS sips and zip — no Homebrew, no Python, no ImageMagick.

Why this exists

iPhones shoot HEIC by default. HEIC is poorly supported on Windows and in a lot of appraisal / CRM / dealer / insurance software, so recipients hit a wall: they can see the file but can't open or import it, and free online converters are flaky. Re-encoding to JPEG once, locally, removes that wall for everyone downstream.

When to use

  • A recipient says they "can't open" / "can't convert" your photos (HEIC → JPEG).
  • You're handing a photo set to a non-technical person or to software that wants JPEG.
  • You're prepping images to drop on a static host (see the companion cloudflare-workers-publish skill) and want a gallery + a bulk-download ZIP.

For the full end-to-end playbook (pull from a cloud album → bundle → host unlisted → share via a gist gateway), see the photo-gallery-delivery skill, which orchestrates this one.

Quick start

SKILL_DIR="$(dirname "$(find ~/.claude ~/eon -path '*/heic-to-jpeg-bundle/scripts/make-bundle.sh' 2>/dev/null | head -1)")"

# Gallery + password-protected ZIP that fits the Cloudflare Workers 25 MiB cap:
bash "$SKILL_DIR/make-bundle.sh" \
  --src ~/Pictures/my-photos \
  --title "2023 Corolla Cross — trade-in photos" \
  --zip --password "CorollaCross2023" --zip-cap-mib 25

# Also emit a full-resolution JPEG tier (host its ZIP off a large-file host, not Workers):
bash "$SKILL_DIR/make-bundle.sh" --src ~/Pictures/my-photos --full --zip

Output:

<src>/_bundle/site/index.html        # gallery: thumbnails -> full "view" JPEGs
<src>/_bundle/site/photos/photo-NNN.jpg
<src>/_bundle/site/thumbs/photo-NNN.jpg
<src>/_bundle/site/bundle.zip        # when --zip and it fits the cap
<src>/_bundle/full/photo-NNN.jpg     # when --full (full-res tier)

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.

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.
