What it does
Canvas Edit Text is an agent skill from Xiangyu-CAS/codex-canvas. Recognize visible text in a selected Codex-Canvas image, apply a user-described text edit with imagegen, and collect the result back onto the canvas.
Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Image generation. 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.
When your agent uses it
- Tasks that involve Image generation
Example prompts
- “/canvas-edit-text”
Workflow steps
9 steps, taken from the first numbered list in SKILL.md.
- Treat the selected canvas image as the edit target.
- Before generating, identify the visible text in the image and write a formatted text inventory to the job output directory path supplied…
- Use the user's Edit Text instruction as the primary edit instruction.
- Use imagegen once to create the edited image.
- Preserve non-text content, aspect ratio, composition, colors, perspective, typography style, and design intent.
- Only change text requested by the edit instruction. Keep unchanged visible text as-is.
- If the source image is a transparent layer, render the edited layer on a flat solid #ff00ff chroma-key background so Codex-Canvas can…
- 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 place it in a row to the right of the source image.
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 Edit Text loads about 365 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 202 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.

- description
- Recognize visible text in a selected Codex-Canvas image, apply a user-described text edit with imagegen, and collect the result back onto the canvas.
Codex-Canvas Edit Text
Use this skill when the user invokes Edit Text from Codex-Canvas or asks to modify visible text inside a selected canvas image.
Behavior
- Treat the selected canvas image as the edit target.
- Before generating, identify the visible text in the image and write a formatted text inventory to the job output directory path supplied by Codex-Canvas.
- Use the user's Edit Text instruction as the primary edit instruction.
- Use imagegen once to create the edited image.
- Preserve non-text content, aspect ratio, composition, colors, perspective, typography style, and design intent.
- Only change text requested by the edit instruction. Keep unchanged visible text as-is.
- 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.
- 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 place it in a row to the right of the source image.
Do not ask follow-up questions from a background Edit Text job. Make the most reasonable text edit from the provided instruction.
