description	Drafts or revises a section of an astrophysics or cosmology manuscript based on hmfast results. Use when the user asks for a draft, an edit pass, or a publishability review of a section, including its figures.

Write paper section

Follow .claude/rules/paper-writing.md strictly. Highlights:

• No em dashes or en dashes as prose punctuation. Replace with comma, semicolon, colon, or parentheses. En dashes inside numeric ranges in equations are acceptable only when the journal style sheet requires it.
• Define every symbol on first use. Past tense for what was done, present tense for results.
• Quantitative claims only: every "improves", "matches", or "agrees" needs a number and an uncertainty.

Drafting workflow

1. Read the latest version of the section in the manuscript repo.
2. Read the result files (run.json, plots, tables) the section will reference.
3. Draft prose that points to specific figures and tables by \ref{} label, not "the figure above".
4. Insert \citep{?} placeholders for any reference you are not sure about; do not invent citations.

Figure review (mandatory, VLM-driven)

For every figure referenced or added:

1. Generate the figure as PDF (for the manuscript) and PNG (for visual inspection).
2. Open the PNG with the Read tool and inspect it. Check axis labels, units, legibility at print size, color-blind safety, panel alignment, and whether the caption is self-contained.
3. If anything is wrong, fix the plotting script and regenerate. Loop until the figure is publication-quality.
4. Record the final commit hash in the figure's source comment.

Final pass

• grep -nP '[\x{2014}\x{2013}]' <section>.tex and -- and replace any matches.
• Compile the manuscript and confirm there are no missing references or undefined labels.
• Confirm every quantitative claim links back to a number in run.json or a table file.
