HTML Brief Artifact

Produce a standalone HTML brief, not a production app surface.

Review:

• references/implementation-plan-example.html
• references/pr-review-example.html
• references/style-notes.md

Best Fit

• implementation plans;
• status reports;
• PR summaries;
• incident notes;
• research explainers;
• concept briefs.

Not The Best Fit

• live product UI;
• long manuals or knowledge bases;
• spreadsheets or dense data tables better served by other tools;
• vague "make a webpage" requests without a document goal.

Output Contract

Create one self-contained .html file that:

• has no build step or external dependency by default;
• uses clear narrative hierarchy and structured sections;
• includes dark mode with CSS variables, toggle, persistence, and pre-paint theme setup;
• reads cleanly on desktop and mobile;
• stays close to source meaning unless the user asked for a rewrite.

Content Rules

• Preserve the user's meaning. Improve clarity, not authorship drift.
• Organize into a small number of sections with clear labels.
• Use timelines, summary strips, chips, callouts, comparison blocks, or checklists only when they improve scanning.
• Keep copy concrete and operational.
• Do not inflate a short brief into a faux strategy deck.
• If uncertainty exists, label it explicitly instead of smoothing it away.

Visual Rules

• Favor calm, document-like presentation over app chrome.
• Use one accent family and disciplined spacing.
• Let headings carry hierarchy.
• Use cards, tables, and lists as tools, not defaults.
• Avoid generic landing-page composition.

Verification

Before finishing:

1. Open the artifact in a browser.
2. Check desktop and mobile readability.
3. Check long lines, wrapping, and section spacing.
4. Check the theme toggle and persistence.
5. Check print-like readability if the artifact is document-heavy.
6. Report inferred structure or content gaps honestly.

Pair with browser-verification when browser tooling is available.

Final Report

Include:

• output file path;
• brief type;
• source material transformed;
• browser checks run;
• assumptions made.
