What is any-hair-color-swap?

An image-editing prompt that changes the hair color in a portrait to a chosen shade while keeping the person, hairstyle, pose, framing, and background unchanged.

Use it to preview different hair colors in a photorealistic portrait.

It limits the edit to the hair and helps prevent color spilling onto the skin, clothing, or surroundings.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00087	$0.01257
Opus 5.5	$0.00035	$0.00503
Sonnet 5.5	$0.00017	$0.00251
Haiku 4.5	$0.00009	$0.00126

Security

Grade A, and why

any-hair-color-swap 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.

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

What it does

This prompt instructs an AI photo retouching assistant to recolor the hair in a provided portrait to a specified target shade while strictly preserving the person’s identity, facial details, hairstyle, pose, framing, and background. The expected outcome is a photorealistic image where only the hair color changes, maintaining natural strand texture and highlights without any spill onto skin, clothing, or surrounding elements.

Inputs

textInputs

Pass each text input using --input <key>=<value> flags.

Variable key	Required?	Description	Defaults
`Hair_color`	Required	Your description of the hair color	(none)

imageInputs

This prompt requires exactly 1 image. You must pass exactly 1 image flag (no more, no fewer), in the order matching the descriptions below.

Index	Required	Description	Allowed CLI flags
1	Yes	Upload your image (easy to see the hairstyle)	`--image-input-url <url>` or `--image-input-path <path>`

Models and options

This skill's modality is: image.

To discover which model values you can use (and which options keys/values are valid for each model), run:

betterprompt resources --models-only --json

Then filter the returned JSON array to entries where modality is "image".

How to run

Step 1: Collect inputs

First, run betterprompt resources --models-only --json and filter to modality: "image" to discover valid models and available options:

betterprompt resources --models-only --json

Use only the models and option values that appear in the filtered results.

Then collect all inputs from the human:

Required text inputs:
- Hair_color
Required images:
- Exactly 1 images: image 1 (Upload your image (easy to see the hairstyle)). Images must be provided in this order.
Optional: model and options.
- Present the human with the default model gemini-2.5-flash-image-preview and its available options. Look up gemini-2.5-flash-image-preview in the betterprompt resources output (filtered to modality "image") and show its availableOptions as: key: val1, val2 (default), val3 | key2: .... Mark a value (default) if it matches these defaults: {"aspectRatio":"3:4"}.
- If the human does not specify, defaults are used: model gemini-2.5-flash-image-preview, options {"aspectRatio":"3:4"}. Other models from the resources call are also available.

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.
