auto-white-balance

auto-white-balance is a skill for Claude Code from danielrosehill/Claude-Image-Production-Plugin. It costs 92 tokens per session (1,479 once invoked), scanned A, original, MIT.

An image-editing skill that corrects unwanted colour casts, such as yellow indoor light or blue-green underwater lighting.

In plain words
What is it for?
It helps correct indoor photos, aged scans, underwater images, and batches of gallery pictures.
Why use it?
It removes the need to fix colour balance by hand and can make images from different lighting conditions more consistent.

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

auto-white-balance 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 12d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Auto White Balance

Neutralise colour casts without per-image manual correction. Three algorithms, one CLI.

  • gray-world (default) — assume the average of the scene is neutral grey. Scale each RGB channel so its mean equals the global mean. Robust on most natural scenes.
  • white-patch — assume the brightest pixels are white. Per-channel -auto-level stretches each channel to full range. Strong correction; fails on scenes lacking a true white reference.
  • combined — gray-world first, then a gentle white-patch pass at 50% strength. Good default for mixed-light indoor shots.

When to use

  • Indoor photos under tungsten/fluorescent/LED with the wrong WB preset.
  • Scanned prints / slides with age-related cast.
  • Underwater or aquarium shots (heavy blue/green cast).
  • Batch normalisation before publishing a gallery shot across multiple lighting conditions.

Do not use this skill when:

  • Source is a RAW file (CR2/NEF/ARW/DNG/RAF) — use darktable-cli with --apply-custom-presets and the temperature module set to as shot to reference. White-balancing a baked JPEG throws away headroom that's still in the RAW.
  • The cast is intentional (golden hour, sodium streetlamps for mood, blue-hour landscapes). Auto-WB will flatten it.
  • The image is a deliberately monochromatic / toned edit.

Inputs

  1. Input — file or directory. Required.
  2. Modegray-world (default) | white-patch | combined.
  3. Recursive--recursive for directory descent.
  4. Output — default in-place suffix _wb next to the source. --output-dir <path> to write into a sibling folder. --overwrite to replace.
  5. Strength0.0 to 1.0 (default 1.0). Blends the corrected image with the original via -compose blend -define compose:args=<pct>. Use 0.5 for a softer touch.
  6. Preserve luminance — default on. After channel scaling, rescale so the mean luminance matches the original (prevents brightness drift). --no-preserve-luma to disable.

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.
