description: Top-level markdown-to-HTML router. Classifies the input markdown (document / review / slides), checks the design-system onboarding gate + 100-line threshold, then forks context to the right converter sub-skill via the markdown-html-orchestrator skill. Returns a ≤100-word digest with input lines, output path, design style, top features used, and one forcing question. argument-hint: ""

/cs:markdown-html — Markdown-to-HTML router

Route this conversion through the markdown-html-orchestrator skill:

$ARGUMENTS

Pre-flight gates (refuse and surface, never override)

1. Input < 100 lines. Markdown still wins below the threshold (Shihipar). Refuse with the line count + recommendation to keep as markdown.
2. Design-system not onboarded. Surface python3 markdown-html/skills/design-system/scripts/onboard.py and re-prompt after.
3. Output directory unwritable. Refuse; let the user fix the path or re-onboard.

Routing (deterministic, two-signal threshold)

Signal class	Filename hints	Content signals	Sub-skill
DOCUMENT	report.md, spec.md, rfc-*.md, *-doc.md, *-analysis.md, *-explainer.md	## Table of Contents, ^# , ^## , table rows, GFM callouts	md-document
REVIEW	review.md, *-pr-*.md, *.diff.md, code-review*.md	```diff, ^[-+]{3} , ^@@, > [!BLOCKER]/[!MAJOR]/[!MINOR]/[!NIT], LGTM/nit:/blocker:	md-review
SLIDES	deck.md, slides.md, *-talk.md, presentation*.md	^---$ ≥ 3, <!-- notes:, H1 cadence ≥ 5 with median gap ≤ 12 lines	md-slides

Pipeline:

python3 markdown-html/skills/markdown-html-orchestrator/scripts/doctype_classifier.py \
    --input "$ARGUMENTS" --output json \
  | python3 markdown-html/skills/markdown-html-orchestrator/scripts/route_explainer.py

python3 markdown-html/skills/markdown-html-orchestrator/scripts/output_path_resolver.py \
    --input "$ARGUMENTS" --doctype <verdict>

1. Silent-route only when winner ≥ 3 AND (runner-up = 0 OR winner ≥ 2× runner-up).
2. Single signal or tie → one clarifying question with a recommended answer.
3. No signals → ask which lane, recommend md-document as the safe default.

Output (≤ 100-word digest)

• Input lines + doctype
• Output path (resolved by output_path_resolver.py)
• Design style + brand primary applied (from config_loader.py)
• Top 3 features used (sticky TOC, scrollspy, code-copy, severity badges, presenter mode, etc.)
• One forcing question for the user (cite Shihipar / WCAG / Lupton / Tufte)

Hard rules

• Never silently chain two converters. Pick one, finish, ask before chaining.
• Never override a REFUSE from route_explainer.py.
• Never invent brand colors when the user hasn't onboarded. Surface onboarding.
• Output is single-file HTML. External CDN is limited to Google Fonts + Prism.js.

Status

All five skills are live (orchestrator + design-system + the three converters). This command runs the classifier + design-system gate, then hands the conversion to the routed converter sub-skill (/cs:md-document, /cs:md-review, or /cs:md-slides). Never render HTML inline — the converter scripts own the rendering.
