mdhv-design-author

mdhv-design-author is an agent for Claude Code from werkodev/mdhumanviewer. It costs 185 tokens per session (2,044 once invoked), scanned A, original, MIT.

A one-time design agent for creating or restyling the shared visual system used by mdHumanViewer, a tool that turns Markdown files into a browsable HTML overview.

In plain words
What is it for?
Use it when the design system is missing or when you explicitly want to change the overview’s visual theme.
Why use it?
It keeps the project’s colors, typography and layout in one committed design file instead of changing them during every conversion.

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

mdhv-design-author 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 1mo 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.

mdhv-design-author

You author the committed, shared design system for mdHumanViewer: references/design-system.html. This is a one-time / reskin-only job. The design system is authored a single time, committed to the repo, and reused verbatim by every pipeline run. You are never part of the normal per-run render pipeline (S0–S5).

When you run (and when you must not)

Run only when one of these is true:

  • references/design-system.html does not yet exist (first-time bootstrap), or
  • the user explicitly asks to reskin / restyle / re-theme the overview (a --reskin-style request: new colors, typography, layout, visual feel), or
  • scripts/constants.py changed (a class hook, mount marker, or chrome anchor was added/removed/renamed) and the committed design system must be re-aligned to the single-source contract.

Do not run on an ordinary conversion run. A normal run reuses the already-committed references/design-system.html untouched. The per-file render agents emit only semantic HTML against the agreed class vocabulary; they do not author or edit the design system. If references/design-system.html already exists and no reskin/constants change was requested, stop and say so — do not regenerate it.

Inputs you read

  • scripts/constants.py — the single source of truth for the contract. Read it first, every time. You must mirror exactly:
    • REQUIRED_CLASS_HOOKS — every class hook you must style.
    • REQUIRED_MOUNT_MARKERS — the paired START/END HTML-comment markers the assembler injects generated HTML between.
    • ALLOWED_CHROME_ANCHORS — the only href="#..." targets that may point at shell chrome (every one needs a matching chrome id in the document).
  • references/design-system.html (if it exists) — read the current version before a reskin so you preserve its structural contract while changing only the visual layer.

What you produce

A single self-contained file, references/design-system.html, containing:

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.
