HTML Summary

Convert a stakeholder summary markdown file into a single self-contained HTML report tailored for executive readers — bottom line and decision asks up front, supporting detail later — styled with a Test Double-derived palette. The skill produces one HTML file next to the source markdown and stops there.

Inputs

Source markdown file — usually a stakeholder-summary.md inside a planning folder. If the user does not name one, ask. Do not guess.

Output

HTML sibling file — written next to the source markdown, same basename, .html extension. Example: filters-and-saved-views/stakeholder-summary.md → filters-and-saved-views/stakeholder-summary.html. This is the only artifact the skill produces.

Hard rules

Single file, no external network resources. No <link rel="stylesheet">, no <script src=...> pointing at a CDN, no remote font loading, no remote images. Inlined JavaScript libraries (such as mermaid.js) are allowed and expected — they keep the file self-contained.
Inline all CSS in a <style> block in <head>. The file must render correctly offline.
Do not modify the source markdown. This skill is one-way: markdown in, HTML out.
Do not commit, push, or publish. The skill writes the HTML file to disk and reports its path. Sharing the file is the user's call, outside this skill.
Executive ordering is non-negotiable. Bottom line (TL;DR) and the stakeholder asks appear before any other content, in that order. Restructure if the source markdown puts them later. See references/layout-principles.md.
Use the report palette only. Colors, typography, spacing, and component patterns come from references/report-style.md. Do not invent new accent colors.
Header: subject as the title, fixed subtitle, no brand mark. The <h1> is the summary subject (the feature name). The .subtitle beneath it is the literal string Han: Stakeholder Summary on every report. The header carries no logo or brand mark.
No superlatives in user-visible text. Banned word lists and rewrite patterns live in references/writing-conventions.md. Verify before finishing.
Apply the shared readability standard to prose. Load and apply ../../references/readability-rule.md to the prose content this skill writes or transfers, holding the named audience — the non-technical stakeholder. The report's visual layout stays governed by references/layout-principles.md and references/report-style.md.
Preserve the source's plain-language framing. Do not rewrite content to be more technical or more abstract. Keep the source's wording where it works; tighten only when restructuring for the executive layout.

Process

1. Locate the source markdown

If the source path is not in the conversation, ask for it. Resolve to an absolute path and confirm it exists. The output HTML path is the source path with .md replaced by .html.

2. Read the source end-to-end

Read the entire markdown file. Identify which of these sections (or equivalents) are present, in any order:

The bottom line / executive summary / TL;DR (sometimes implicit — derive from the opening paragraph)
The stakeholder asks / open decisions (sometimes titled "What we are asking stakeholders" or similar)
The problem statement
What the change opens up / outcomes
User experience walkthrough
Today-vs-after data flow comparisons (sometimes with mermaid diagrams)
What is intentionally not in scope

Section titles in the source may not match these names exactly — map by content, not heading text.

3. Load the references

Read all references before producing HTML:

references/report-style.md — palette, typography, mermaid theming, component patterns, accessibility notes.
references/layout-principles.md — executive ordering, what hoists to the top, full-width data-flow rule, mermaid diagram preservation rules.
references/writing-conventions.md — banned words (no superlatives), rewrite patterns, tone signals.
references/html-template.html — the canonical reference HTML. Use its structure, class names, and CSS verbatim. Adapt content; do not invent new styles.

4. Produce the HTML

Write the HTML file to the output path. Required structure, in order:

Header — <h1> set to the summary subject (the feature name) with the most evocative noun phrase wrapped in <span class="highlight">; .subtitle set to the literal string Han: Stakeholder Summary. No brand mark.
Bottom line card — purple accent strip; one-sentence lead in larger type; 4–8 outcome bullets in a two-column list.
Stakeholder asks card — orange accent strip; numbered list of decisions the team needs from stakeholders. Each ask has a short title and a one-paragraph question ending with **Confirm ...?**. If the source has no asks section, omit this card entirely — do not invent decisions.
Problem statement section.
What this opens up section — outcome bullets.
User experience walkthrough section — numbered walk list.
Data flow section — today and after cards stacked one per row, each card spanning the page wrap's content width. Do not place data-flow cards side-by-side in a .grid-2 wrapper. Each card contains a <pre class="mermaid"> block with the source's mermaid syntax preserved (branching, decision diamonds, labeled edges). Normalize style directives to the report palette per references/report-style.md.
Intentionally not in scope section — out-of-scope list.

Readability of the prose. The text in these sections follows the shared readability standard (../../references/readability-rule.md) — do not duplicate its text, apply it. Lead with the main point (bottom line up front, which the executive ordering already enforces), give each heading a descriptive name rather than a generic label, keep one idea per paragraph with the first sentence carrying it, number sequential steps and bullet non-sequential items, and reveal detail in layers. This governs the prose only; the visual layout stays governed by the layout conventions above.

The template includes a mermaid bundle placeholder near the end of <body>:

html

<script id="mermaid-bundle"><!-- MERMAID_BUNDLE_INLINE_HERE --></script>
<script>
  mermaid.initialize({ ... });
</script>

Leave the placeholder string  exactly as written. The inliner script in Step 6 replaces it with the vendored mermaid.min.js bundle. The mermaid initialization block (with the report palette theme variables) is also part of the template — paste it verbatim.

Section omission rules:

Omit any section the source markdown does not address. Do not invent content to fill a section.
The bottom line card is the only required section other than the header — if the source has no explicit TL;DR, derive one from the opening paragraph and clearly mark it as such in your work notes.

Markup rules:

Use the entity — not — for em-dashes in HTML body content (the template does this consistently).
Use the entity → for arrows in flow diagrams.
Apply class names verbatim from the template — tldr, ask-block, ask, walk, flow, node, node.good, node.bad, node.start, out-of-scope, chip, chip.good, chip.bad.
Wrap the feature-name portion of the <h1> in <span class="highlight"> for the green background.

5. Verify the HTML

Open the file you just wrote and confirm:

The <style> block exists in <head> and contains the :root palette variables from references/report-style.md.
There are no <link>, <script src=...>, or external url(...) references in <head> or <body>.
The <h1> is the summary subject and the .subtitle reads Han: Stakeholder Summary.
Every section that exists in the source markdown has a corresponding section in the HTML.
The bottom-line card and asks card (if present) appear before any other content section.
No banned superlatives appear in user-visible text (see references/writing-conventions.md).

Then run the standardized readability self-check from ../../references/readability-rule.md over the report's PROSE content only — never inside HTML tags, attributes, class names, mermaid/diagram bodies, or code. The visual layout stays governed by the existing layout conventions. This skill runs no rewrite pass, so this self-check is the fidelity guard on the prose; criterion 6 is not optional. Confirm each criterion and fix any failure before finalizing:

The opening line/prose states the main point (bottom line up front).
Each heading names its content and is not a generic label.
Each paragraph carries one idea and leads with it.
No sentence runs past the soft length flag (about thirty words) without reason.
No word from the vocabulary blocklist (the shared writing-voice profile's "Avoided words and phrases" and "AI slop to avoid" lists, plus this skill's supplementary domain terms in references/writing-conventions.md) is present.
Every fact is preserved — every claim, quantity, named entity, and stated condition or qualifier survives with its precision intact.

Fidelity wins: the standard governs how the content is said, never whether a required fact appears.

If any check fails, fix it before Step 6.

6. Inline the mermaid bundle

Make the file self-contained by inlining the vendored mermaid bundle in place of the placeholder:

${CLAUDE_SKILL_DIR}/scripts/inline-mermaid.sh <path-to-html-file>

The script is idempotent: it replaces the  placeholder with the contents of assets/mermaid.min.js. If the report has no diagrams (no placeholder), it leaves the file untouched and exits cleanly. If the script exits non-zero, surface the error to the user; do not retry blindly — read the error.

7. Report

Tell the user:

The output file path.
That the diagrams were inlined (or that the report had no diagrams to inline).

If you had to derive the bottom line because the source had no explicit TL;DR, mention that so the user can review the framing.
