Three tasks. One skill.

Read design/design.md before any CREATE or REFORMAT work.

Route table

| User intent | Route | Scripts used | |---|---|---| | Generate a new PDF from scratch | CREATE | palette.py → cover.py → render_cover.js → render_body.py → merge.py | | Fill / complete form fields in an existing PDF | FILL | fill_inspect.py → fill_write.py | | Reformat / re-style an existing document | REFORMAT | reformat_parse.py → then full CREATE pipeline |

Rule: when in doubt between CREATE and REFORMAT, ask whether the user has an existing document to start from. If yes → REFORMAT. If no → CREATE.

Route A: CREATE

Full pipeline — content → design tokens → cover → body → merged PDF.

bash scripts/make.sh run \
  --title "Q3 Strategy Review" --type proposal \
  --author "Strategy Team" --date "October 2025" \
  --accent "#2D5F8A" \
  --content content.json --out report.pdf

Doc types: report · proposal · resume · portfolio · academic · general · minimal · stripe · diagonal · frame · editorial · magazine · darkroom · terminal · poster

| Type | Cover pattern | Visual identity | |---|---|---| | report | fullbleed | Dark bg, dot grid, Playfair Display | | proposal | split | Left panel + right geometric, Syne | | resume | typographic | Oversized first-word, DM Serif Display | | portfolio | atmospheric | Near-black, radial glow, Fraunces | | academic | typographic | Light bg, classical serif, EB Garamond | | general | fullbleed | Dark slate, Outfit | | minimal | minimal | White + single 8px accent bar, Cormorant Garamond | | stripe | stripe | 3 bold horizontal color bands, Barlow Condensed | | diagonal | diagonal | SVG angled cut, dark/light halves, Montserrat | | frame | frame | Inset border, corner ornaments, Cormorant | | editorial | editorial | Ghost letter, all-caps title, Bebas Neue | | magazine | magazine | Warm cream bg, centered stack, hero image, Playfair Display | | darkroom | darkroom | Navy bg, centered stack, grayscale image, Playfair Display | | terminal | terminal | Near-black, grid lines, monospace, neon green | | poster | poster | White bg, thick sidebar, oversized title, Barlow Condensed |

Cover extras (inject into tokens via --abstract, --cover-image):

• --abstract "text" — abstract text block on the cover (magazine/darkroom)
• --cover-image "url" — hero image URL/path (magazine, darkroom, poster)

Color overrides — always choose these based on document content:

• --accent "#HEX" — override the accent color; accent_lt is auto-derived by lightening toward white
• --cover-bg "#HEX" — override the cover background color

Accent color selection guidance:

You have creative authority over the accent color. Pick it from the document's semantic context — title, industry, purpose, audience — not from generic "safe" choices. The accent appears on section rules, callout bars, table headers, and the cover: it carries the document's visual identity.

| Context | Suggested accent range | |---|---| | Legal / compliance / finance | Deep navy #1C3A5E, charcoal #2E3440, slate #3D4C5E | | Healthcare / medical | Teal-green #2A6B5A, cool green #3A7D6A | | Technology / engineering | Steel blue #2D5F8A, indigo #3D4F8A | | Environmental / sustainability | Forest #2E5E3A, olive #4A5E2A | | Creative / arts / culture | Burgundy #6B2A35, plum #5A2A6B, terracotta #8A3A2A | | Academic / research | Deep teal #2A5A6B, library blue #2A4A6B | | Corporate / neutral | Slate #3D4A5A, graphite #444C56 | | Luxury / premium | Warm black #1A1208, deep bronze #4A3820 |

Rule: choose a color that a thoughtful designer would select for this specific document — not the type's default. Muted, desaturated tones work best; avoid vivid primaries. When in doubt, go darker and more neutral.

content.json block types:

| Block | Usage | Key fields | |---|---|---| | h1 | Section heading + accent rule | text | | h2 | Subsection heading | text | | h3 | Sub-subsection (bold) | text | | body | Justified paragraph; supports <b> <i> markup | text | | bullet | Unordered list item (• prefix) | text | | numbered | Ordered list item — counter auto-resets on non-numbered blocks | text | | callout | Highlighted insight box with accent left bar | text | | table | Data table — accent header, alternating row tints | headers, rows, col_widths?, caption? | | image | Embedded image scaled to column width | path/src, caption? | | figure | Image with auto-numbered "Figure N:" caption | path/src, caption? | | code | Monospace code block with accent left border | text, language? | | math | Display math — LaTeX syntax via matplotlib mathtext | text, label?, caption? | | chart | Bar / line / pie chart rendered with matplotlib | chart_type, labels, datasets, title?, x_label?, y_label?, caption?, figure? | | flowchart | Process diagram with nodes + edges via matplotlib | nodes, edges, caption?, figure? | | bibliography | Numbered reference list with hanging indent | items [{id, text}], title? | | divider | Accent-colored full-width rule | — | | caption | Small muted label | text | | pagebreak | Force a new page | — | | spacer | Vertical whitespace | pt (default 12) |

chart / flowchart schemas:

{"type":"chart","chart_type":"bar","labels":["Q1","Q2","Q3","Q4"],
 "datasets":[{"label":"Revenue","values":[120,145,132,178]}],"caption":"Q results"}

{"type":"flowchart",
 "nodes":[{"id":"s","label":"Start","shape":"oval"},
          {"id":"p","label":"Process","shape":"rect"},
          {"id":"d","label":"Valid?","shape":"diamond"},
          {"id":"e","label":"End","shape":"oval"}],
 "edges":[{"from":"s","to":"p"},{"from":"p","to":"d"},
          {"from":"d","to":"e","label":"Yes"},{"from":"d","to":"p","label":"No"}]}

{"type":"bibliography","items":[
  {"id":"1","text":"Author (Year). Title. Publisher."}]}

Route B: FILL

Fill form fields in an existing PDF without altering layout or design.

# Step 1: inspect
python3 scripts/fill_inspect.py --input form.pdf

# Step 2: fill
python3 scripts/fill_write.py --input form.pdf --out filled.pdf \
  --values '{"FirstName": "Jane", "Agree": "true", "Country": "US"}'

| Field type | Value format | |---|---| | text | Any string | | checkbox | "true" or "false" | | dropdown | Must match a choice value from inspect output | | radio | Must match a radio value (often starts with /) |

Always run fill_inspect.py first to get exact field names.

---

Route C: REFORMAT

Parse an existing document → content.json → CREATE pipeline.

bash scripts/make.sh reformat \
  --input source.md --title "My Report" --type report --out output.pdf

Supported input formats: .md .txt .pdf .json
