What it does
Canvasengine is an agent skill from RSamaium/CanvasEngine. Work on CanvasEngine projects and .ce components using the official documentation. Use when Codex needs to explain, create, review, or modify CanvasEngine code, especially files ending in .ce, CanvasEngine reactivity with signals, computed, and effect, template directives such as @if and @for, component script/template/style structure, or CanvasEngine-specific syntax that mixes ideas from React, Vue, and Angular.
Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It works with Angular, React and Vue.js. The repository describes itself as: Framework for HTML5 Canvas oriented 2D video games.
When your agent uses it
- Codex needs to explain
- Modify CanvasEngine code
- Especially files ending in .ce
- CanvasEngine reactivity with signals
Example prompts
- “/canvasengine”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Read the summary and section list.
- Identify the Markdown documentation URLs relevant to the user request.
- Fetch the relevant .md pages with curl -L or an equivalent tool.
- Base implementation and explanations on those pages, not on assumptions from React, Vue, Angular, or PixiJS.
- Mention the specific docs or examples consulted when the answer depends on them.
What it can do on your machine
Read from SKILL.md and the folder at commit aee5f6a. 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
Shell commands in SKILL.md call:
curlrg
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
canvasengine.net
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
Canvasengine loads about 808 tokens when it runs. Until then it costs about 107 tokens; SKILL.md has 397 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 397 words (~808 tokens).
“Before answering or editing CanvasEngine code, fetch and read the current documentation index:”
