What it does

The skill calls a photoshop_cutout tool that is not a filter running in the agent's own process. It launches or focuses Adobe Photoshop on a macOS host, opens the image, performs a subject-selection cutout and exports a transparent PNG. The tool then measures the result, including how much background was removed and whether a clean alpha channel exists, and returns a verdict while the before and after images show inline.

Because the tool takes over the host's mouse and keyboard, the first call must use confirmed=false, which only returns a consent question. The agent shows that question, waits for a clear yes, and only then calls again with confirmed=true. Silence, ambiguity or a maybe does not count. Reports must stick to the measured verdict: PASS means the alpha checks passed and the background was removed, while REVIEW means the file was exported but not every transparency check passed.

It recognizes English and Chinese phrasing for the intent, for example remove the background, cut out the product, make a transparent PNG, and the Chinese terms 抠图 and 去背景. Adobe Photoshop must be available on the macOS host.

When your agent uses it

  • Removing the background from a product photo to get a transparent PNG
  • Cutting a person or logo out of an image
  • Chinese-language requests such as 抠图, 去背景 or 做透明 PNG

Example prompts

  • “Remove the background from ./photos/sneaker.jpg and give me a transparent PNG.”
  • “Cut out the person in ./team/headshot.png.”
  • “帮我把 ./logo/brand.png 去背景，做成透明 PNG。”

Requirements

  • Adobe Photoshop on a macOS host
  • The photoshop_cutout tool
  • Your explicit permission for the agent to control the mouse and keyboard

4 steps, taken from the first numbered list in SKILL.md.

  1. You call photoshop_cutout with the path to the source image.

What it can do on your machine

Read from SKILL.md and the folder at commit 3741347. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Photoshop Background Cutout loads about 1.2k tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 621 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Remove the background from an image and produce a transparent PNG by driving the real Adobe Photoshop app on a macOS host. Triggers: remove background, cut out, knock out the subject, isolate the subject, make a transparent PNG, transparent background, delete background. 中文触发词：抠图、扣图、去背景、去掉背景、扣出主体、透明背景、做透明 PNG。

Photoshop Cutout

Use the photoshop_cutout tool to remove the background from an image and deliver a transparent PNG. This is not a filter that runs in this process — it drives the real Adobe Photoshop application on a macOS host, opens the image, runs the cutout, and exports the result.

When To Reach For This

The user wants a subject lifted off its background. Recognize the intent from phrases like:

  • English: "remove the background", "cut out the person/product/logo", "knock out the subject", "isolate this", "make it a transparent PNG", "give me a PNG with no background".
  • 中文：「抠图」「扣图」「帮我去背景」「去掉背景」「把主体扣出来」「要透明背景」「做成透明 PNG」。

How It Works

  1. You call photoshop_cutout with the path to the source image.
  2. The tool launches / focuses Adobe Photoshop, opens the image, performs the subject-selection cutout, and exports a transparent PNG.
  3. The tool measures the result (how much background was actually removed, whether a clean alpha channel was produced) and returns a verdict.
  4. The before image and the after PNG render inline automatically — you do not need to attach or describe them yourself.

Confirm Before Control

This tool seizes the mouse and keyboard of the host machine. It MUST NOT take over the screen without the user's explicit permission.

  1. First call — confirmed=false. Always make the first call with confirmed=false. The tool will return a takeover-consent question (it does not touch the mouse/keyboard yet). Surface that question to the user.
  2. Wait for an explicit yes. Only proceed once the user clearly agrees — a "yes", "go ahead", "do it", "确认", "可以" in the conversation counts. Silence, ambiguity, or "maybe" does not count.
  3. Second call — confirmed=true. Only then call again with confirmed=true. This is the call that actually takes over the host.

Never set confirmed=true on the first call, and never assume consent.

Honesty Protocol

Report only what the tool's measured verdict supports. Do not embellish.

The tool returns a Markdown report whose first line is either **Verdict**: PASS … or **Verdict**: REVIEW …, followed by measured numbers (transparent %, subject %, whether an alpha channel is present).

  • PASS — the alpha checks passed: you may say the background was removed and a transparent PNG was produced.
  • REVIEW — the file was exported but not all transparency checks passed. Say the cutout needs review / is not fully clean — do not claim the background was removed. Offer to retry or refine.
  • Export failed (the verdict text says the cutout PNG was not created, shown as REVIEW) — say it failed and offer to retry or try a different image.

Never claim "done", "cut out", or "transparent" beyond what the verdict and the measured ratios support. The user trusts the numbers, not your optimism.

Usage Protocol

When the user asks for a cutout:

  1. Confirm the source. Make sure you have the path to the image the user wants processed.
  2. First call, confirmed=false. Relay the takeover-consent question.
  3. Get explicit consent. Wait for the user's "go ahead".
  4. Second call, confirmed=true. Run the real cutout.
  5. Report the verdict honestly. State the outcome exactly as measured. The before/after images render inline on their own.

Example

User: "帮我把这张产品图抠图，要透明背景"

  • First, call photoshop_cutout(image_path="/path/to/product.jpg", confirmed=false).
  • The tool replies with a consent question; relay it: "This will take over the mouse and keyboard on the Mac to run Photoshop. Shall I go ahead?"
  • User: "可以，去吧"
  • Then call photoshop_cutout(image_path="/path/to/product.jpg", confirmed=true).
  • Tool returns **Verdict**: PASS. You report: "背景已去除，导出了透明 PNG（结果已通过校验）。" The before/after images appear inline. If it returns REVIEW instead, say the cutout needs another look rather than claiming success.

Do Not

  • Do not drive gui_action directly to attempt the cutout — use this dedicated tool, which knows the Photoshop workflow and measures the result.
  • Do not call with confirmed=true before the user agrees.
  • Do not overstate the result. A REVIEW verdict is not a clean cutout.
