What it does
Canvas Quick Edit is an agent skill from Xiangyu-CAS/codex-canvas. Run a user-described Quick Edit on a selected Codex-Canvas image and collect the result back onto the canvas.

The repository describes itself as: Infinite canvas plugin for codex; Codex无限画布插件，图层分离，涂抹修改. The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit b801839. 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
Canvas Quick Edit loads about 505 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 298 words of instructions outside code blocks.
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.

- canvas-quick-edit
- description
- Run a user-described Quick Edit on a selected Codex-Canvas image and collect the result back onto the canvas.
Codex-Canvas Quick Edit
Use this skill when the user invokes Quick Edit from Codex-Canvas or asks to perform an open-ended edit on a selected canvas image.
Behavior
- Treat the selected canvas image as the edit target.
- Quick Edit may provide one clean source image or two images. When two are attached, image 1 is the clean source and image 2 is an annotation board containing temporary arrows, masks, and edit notes around the source.
- Always use the clean source as the visual base. Use the annotation board only to locate regions and interpret the edit intent; do not preserve its surrounding board background or annotation UI.
- Use the user's optional Quick Edit text together with every arrow label, pencil mask, text note, color, and source-pixel location listed in the prompt. Arrow labels are explicit instructions for their arrow targets.
- Apply the requested edit according to the annotations, then remove all temporary arrows, strokes, boxes, label bubbles, and note text from the final image.
- Preserve the source image's aspect ratio, subject identity, layout, unmentioned visible text, and design intent unless an instruction explicitly asks to change them.
- If the source image is a transparent layer, render the edited layer on a flat solid #ff00ff chroma-key background so Codex-Canvas can recut the alpha channel after generation.
- Generate exactly one revised clean bitmap. Save the final selected output as a PNG under the job output directory provided by Codex-Canvas.
- Codex-Canvas will collect the output, remove the chroma-key background when needed, and replace the running placeholder to the right of the source image. It will preserve the original image and its annotation objects.
Do not ask follow-up questions from a background Quick Edit job. Make the most reasonable edit from the provided instruction.
