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 | $0.00050 | $0.00371 |
| Opus 5 | $0.00025 | $0.00186 |
| Sonnet 5 | $0.00010 | $0.00074 |
| Haiku 4.5 | $0.00005 | $0.00037 |
Grade A, and why
exif-stripper 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 9d 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.
What it actually says
EXIF Metadata Stripper
Automatically detects and strips sensitive EXIF metadata from images before they are published.
When to Activate
- User is adding images to a blog post, website, or public content
- User mentions EXIF data, metadata, GPS coordinates, or image privacy
- User is preparing images for deployment or publishing
- User stages image files for a git commit
What to Do
-
Proactively remind the user to check images for sensitive metadata when they add images to public-facing content.
-
Audit first — run the check script to see what metadata exists:
./scripts/check-exif.sh <path> -
Strip if needed — remove sensitive metadata while preserving display-critical data:
./scripts/strip-exif.sh <path>
What Gets Stripped vs Preserved
Stripped (privacy-sensitive):
- GPS coordinates and location data
- Camera serial numbers
- Software and editing history
- Owner/artist names
- Thumbnail and preview images
- Maker notes
Preserved (display-critical):
- Orientation (prevents rotated images)
- ICC color profile (ensures accurate colors)
Important Notes
- Always audit before stripping so the user knows what was found
- If you install the optional hook files, staged images can be cleaned automatically before commit
- Supported formats: JPG, JPEG, PNG, TIFF, WebP
- Requires
exiftoolto be installed
What ships with it
3 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.

exif-stripper is a skill published in the GitHub repository ethanolivertroy/my-agent-stuff (11 stars, last pushed 2mo ago), licensed MIT. It adds 50 tokens to every session and 371 once invoked, about $0.0003 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.
