photo-editing
Skill0 starsChanged 48 days agoMITView on GitHub
Photo development and retouching with darktable 5 (RAW/JPEG development, color grading, batch styles), GIMP 3.2 (retouching, compositing), ImageMagick and exiftool (metadata), with headless batch processing in a reproducible container. Use when the user wants to edit, color-grade, batch-process, resize for web, watermark, or strip location/metadata from photos, or wants a consistent look across a photo set (portfolio, product shots, headshots).

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
1 rule. About 0 are common, 0 are distinctive, and 1 is very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈0
Distinctive · estimate
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 39
Never edit originals: darktable keeps edits in .xmp sidecars (batch-develop.sh reuses them).
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Photo editing (darktable · GIMP · exiftool)
Scripts run inside the design-skills container automatically (bash <skill-dir>/scripts/<name>.sh …, see
design-sandbox). batch-develop.sh needs the full image; everything else runs in core.
Toolkit
| Tool | Use it for | CLI (in the container) |
| darktable 5 (full image) | Non-destructive RAW/JPEG development: exposure, color, grading, lens fixes, batch looks | desktop app · darktable-cli in.raw [edits.xmp] out.jpg --style NAME |
| GIMP 3.2 (full image) | Pixel retouching: object removal, healing, compositing | desktop app |
| exiftool | Read/strip metadata (GPS!), rename by date | exiftool |
| ImageMagick 7 | Resize, sharpen, watermark, contact sheets | magick |
| AI upscaling (optional, desktop) | 2×/4× upscaling of small or old photos | Upscayl (Windows/macOS/Linux) |
Scripts
| Script | What it does |
check.sh | Verifies darktable-cli, GIMP, exiftool, ImageMagick; lists .dtstyle files in the folder |
batch-develop.sh <style.dtstyle|name|-> <photos…> | Headless darktable export, optionally applying a style, into export/ (FORMAT=jpg|tif|png|webp, WIDTH=0) |
web-ready.sh <photos…> [--max 2048] [--watermark "© You"] [--quality 85] | Resize, light sharpen, strip metadata, optional watermark → web/ |
strip-metadata.sh [--no-backup] <photos…> | Removes GPS, camera serial, software tags; keeps orientation + color profile; backups as *_original |
contact-sheet.sh <photos…> [-o sheet.jpg] [--cols 5] | One JPEG grid of thumbnails to review/share a set |

Rules of thumb
- Develop in darktable first (global look), then GIMP only for local pixel fixes — round-trip via 16-bit TIFF.
- Never edit originals: darktable keeps edits in
.xmpsidecars (batch-develop.shreuses them); exports go toexport/. - Strip metadata before publishing anything online (
strip-metadata.shorweb-ready.sh). - For a consistent set: grade one hero photo, save it as a style, export the
.dtstylenext to the photos, apply to the rest withbatch-develop.sh look.dtstyle *.raw.

Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
