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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Rogue Agent · line 124 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.
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 | $0.00137 | $0.01934 |
| Opus 5 | $0.00068 | $0.00967 |
| Sonnet 5 | $0.00027 | $0.00387 |
| Haiku 4.5 | $0.00014 | $0.00193 |
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 5d 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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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-publishskill) 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.

heic-to-jpeg-bundle is a skill published in the GitHub repository terrylica/cc-skills (72 stars, last pushed yesterday), licensed MIT. It adds 137 tokens to every session and 1,934 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 2026-09-05.
