doc-visual

A document-conversion skill that turns one Markdown file into a visual HTML report with diagrams matched to its sections. Markdown is plain text formatted with simple symbols for headings, lists, and other structure.

In plain words
What is it for?
Use it to illustrate a Markdown document, create a visual report, or produce HTML or Markdown output in a chosen language.
Why use it?
It helps readers understand a text-heavy document without creating diagrams and layout by hand. It reads the complete source document so important details are not reduced to summaries.

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 C, and why

doc-visual scanned grade C with 1 finding 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 2d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 380 lines — stays where its author put it; the contents beside it link to each section on GitHub.

doc-visual

Read a markdown document and write a visual report with diagrams that match each section's meaning. Output is HTML (default) or markdown. You write the output directly — no templates, no intermediate JSON, no agent chains.

Why this matters

The previous version of this skill passed text through a pipeline of agents — each one only saw the output of the stage before it. By the time the report was assembled, the original content had been compressed into summaries of summaries. That's the failure mode you're replacing. You see the original document in full. That's the core advantage. If you find yourself writing "this section discusses X" instead of explaining X — that's compression, and it's the exact failure this redesign exists to fix.

Input

Argument = single markdown file path. Directories, URLs, stdin not supported.

  1. Validate file exists + markdown extension (.md, .markdown, .txt)
  2. Missing/no permission → abort immediately
  3. Read the full file content

Format detection

Flag Values Default
--format html / md html
--lang ISO code auto-detected from document
--local switch off — capable HTML publishes to an Artifact by default
--artifact switch retained no-op alias (already the default on capable HTML)

The report language must match the source document's language.

Channel is decided by the shared contract, not re-derived here — read ${CLAUDE_PLUGIN_ROOT}/references/design-system/channel-decision.md (SSOT, restates ADR 0009) for the (Format × capable) → channel table, flag semantics, and the optimistic-try-then-regenerate rule. The short version: capable HTML publishes to a claude.ai Artifact by default; --local forces the local design-system + Mermaid file; md and non-capable sessions stay local.

--local forces local (analytical charts, zoom/pan) and also triggers on natural-language equivalents — "keep it local", "don't publish", "just the local file" — in whatever language the user writes. --artifact is the retained alias for the now-default behavior and still triggers on "as an artifact", "publish as a link", "share as a URL"; if --local and --artifact are both signalled, --local wins.

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.

doc-visual is a skill published in the GitHub repository LeeJuOh/claude-code-zero (51 stars, last pushed 2d ago), licensed MIT. It adds 86 tokens to every session and 6,006 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
