What it does

Canvas is an agent skill from Kevin100202/Rocket-Design-and-Manufacturing-Automation-Program-from-Shenzhen22highschool. Present HTML on connected OpenClaw node canvases, navigate/eval/snapshot, and debug canvas host URLs.

Its SKILL.md is about 610 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Rocket Design and Manufacturing Automation Program By Students.

Example prompts

  • “/canvas”

Workflow steps

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

  1. Ensure Canvas plugin host is enabled.
  2. Put HTML/CSS/JS under plugins.entries.canvas.config.host.root or the default state canvas dir.
  3. Use a route reachable by the target node.
  4. Present the hosted URL: /openclaw/canvas/.html.
  5. Use snapshot when the user needs proof.

What it can do on your machine

Read from SKILL.md and the folder at commit f924634. 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 (its code samples are json).

    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 loads about 608 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 226 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~608

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 226 words (~608 tokens).

“Use canvas to show HTML on connected Mac/iOS/Android nodes.”
