ce-markup

ce-markup is a skill for Claude Code from waveriderai/ce-design-flow. It costs 152 tokens per session (1,453 once invoked), scanned A, original, MIT.

A browser-based review step for an Open Design artifact, such as a preview page or mockup. It lets a person mark up, comment on, or edit the artifact, then returns the updated work to the terminal.

In plain words
What is it for?
Use it during wireframe reviews, detailed design reviews, or checks that compare a built interface with its mockup.
Why use it?
It prevents the coding agent from continuing with an old version after a person changes the design in the browser.

Written for Claude Code: $CLAUDE_PLUGIN_ROOT variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ce-markup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CE Markup — the browser round trip

One job: hand the artifact to the human in a live browser, and pick it back up correctly when they return. This is a re-entrant step — call it at any gate (wireframe review, hi-fi review, or verifying a built UI against its mockup), as many times as you need.

Why it needs a skill at all

The failure mode is not opening the browser. It is coming back. The agent remembers the state of the file as of before the human edited it, then keeps working from that stale memory — silently discarding what the human just did. Everything below exists to prevent that one bug.

Going out

  1. Identify the artifact: project id + file name. If you just finished a run, that is the run's project and the *.html in the project root. If unsure, list the project's files and pick by mtime.
  2. Resolve the portal host — never hardcode it:
    OD_HOST=$("$CLAUDE_PLUGIN_ROOT/scripts/od-host.sh")
    
    Prints 127.0.0.1 when you are local. Prints the machine's LAN/Tailscale address when you are working over SSH — because the browser runs on your laptop, and localhost there would point at the wrong machine.
  3. Print the URL and stop.
    http://$OD_HOST:60301/projects/<projectId>/files/<file.html>
    
    Say plainly what the human can do there, and that you will wait:

    Open this and change whatever you want — chat with the agent in the composer, or use markup/comments to click an element and describe the change. Edits save straight to the project file. When you're done, come back and say "continue".

  4. Do not poll, do not guess, do not keep working. The human is the gate.

What the human can do in there

In the portal What it does
Type in the composer Conversational iteration with the inner agent, in that project's conversation
Markup / comment on an element Pin a comment to a specific element, then describe the change
Manual edit mode Edit the artifact directly, no agent involved
"Choose design system" dropdown Swap the brand skin (takes effect at hi-fi; wireframe templates ignore it)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
