seed-deck

The Pitch Deck Designer turns the plan into the ten slides a partner flips through in three minutes. Each slide carries one idea in a line or two, and the numbers come from the files, not from memory: the competitors' weak points from their own reviews, the market from sourced inputs, the unit economics and the three years of revenue from the model, the use of funds from the raise. The deck is a single HTML file you can open anywhere, present with the arrow keys and print to PDF. A good deck earns a meeting; it does not guarantee a check. Investors decide.

${CLAUDE_SKILL_DIR} below is this skill's folder (where this SKILL.md lives).

python3 "${CLAUDE_SKILL_DIR}/deck.py" outline               # what each slide will say, with its word count
python3 "${CLAUDE_SKILL_DIR}/deck.py" build                 # seed/deck.html, then the lint
python3 "${CLAUDE_SKILL_DIR}/deck.py" build --brand "#2F6FEB" --ink "#0E1B33" --accent "#FFB020"
python3 "${CLAUDE_SKILL_DIR}/deck.py" lint                  # exit 0 clean, 1 something to fix

Other flags: --dir PATH (default ./seed), --plan PATH, build --out PATH, --json on outline and lint.

What it reads and writes

file	what
seed/plan.json	from /seed-plan (after plan.py build): each section's pitch and points, the tagline, team, brand colours and the numbers block
seed/model.json, seed/market.json, seed/competitors.json, seed/config.json	read by the lint only: every number on a slide must be in one of them or in plan.json, and plan.json must not be older than model.json
seed/deck.html	build writes it: one file, 10 slides, 16:9 (1280 x 720), inline CSS and a few lines of plain JavaScript

The ten slides

#	slide	what is on it
1	Title	the name, the tagline, the raise and the instrument, the founder
2	The problem	the problem line and the competitors' review evidence ("106 of 341")
3	The solution	the solution line and up to 3 points
4	The market	the market line and TAM, SAM, SOM (the circles are not to scale), with sources
5	Competition	one card per competitor (rating, ratings, weak point) and yours
6	Business model	price, what you keep, contribution, LTV:CAC, CAC payback
7	Go to market	the line and up to 3 numbered steps
8	Team	the people in plan.json, with initials
9	Financials	revenue for years 1 to 3 as bars, breakeven month, peak burn
10	The ask	the ask line, the instrument, the use of funds as bars with shares

Presenting: open the file in a browser. Right arrow, space or Page Down moves on; left arrow or Page Up goes back; Home and End jump; a click on the right or left half moves too; #4 in the address opens slide 4; P prints. Without JavaScript the slides simply stack. Print > Save as PDF gives one 16:9 slide a page (13.333 x 7.5 in), backgrounds included.

The lint

• 35 words or fewer in a slide's body. The title, the footnote and the page number do not count.
• One idea a slide: a lead of at most 2 sentences and at most 3 points.
• The ask adds up: the use of funds equals the raise.
• Every number traces: each number shown (rounded is fine: $8.5B for 8,520,000,000, $2.23 for 2.225) is in plan.json's numbers, model.json, market.json, competitors.json or config.json. Years and counts of 10 or less are not checked.
• Nothing missing: no empty slide, no market, competition, business model, financials or ask slide without its data, no team, no stale plan.

Steps

1. Make sure /seed-plan has run plan.py build with every check passing. The deck refuses a plan.json without numbers.
2. Run deck.py outline and read the ten slides back to the founder. Tight lines win: if a slide runs long, shorten the section's pitch or points in seed/plan.json and run plan.py build again.
3. Ask for the brand colours (or keep the ones in plan.json), then run deck.py build.
4. Fix everything the lint lists. Numbers are fixed at their source (the model, the market file), never by editing the HTML.
5. Open seed/deck.html with the founder. Offer the PDF: Print > Save as PDF.
6. Hand off: /seed-coach drills the questions this deck invites, /seed-dataroom files it under 02 Pitch deck, and /seed-closer links it in the outreach.

Example: the reel

Leashly (fictional), from the reel's plan. deck.py outline gives:

 1. Leashly          12 words  Dog walks without the surprise fees. | Raising a $1.5M seed · post-money SAFE
 2. The problem      29 words  Owners pay fees on top of fees. Walkers cancel last minute. | 106 of 341 | ...
 4. The market       28 words  $158B US pet spend (2025). 71M US homes have a dog. | TAM | $8.5B | ...
 5. Competition      33 words  Rover: fees. Wag!: cancellations. | Rover | 4.9★ · 515,771 ratings | ...
 6. Business model   23 words  15% take rate. No owner fee. | $25 | a walk | $3.75 | we keep (15%) | ...
 9. Financials       27 words  Breakeven in month 29 on the seed alone. | Revenue | Year 1 | $467K | ...
10. The ask          28 words  $1.5M seed to launch in 3 cities. | Post-money SAFE | Product and engineering | ...

The problem slide shows Rover's 106 of 341 and Wag!'s 81 of 324; the market slide TAM $8.5B, SAM $228M, SOM $22.8M; the business model $25 a walk, $3.75 kept, $2.23 contribution, 4.24x LTV:CAC, 3.37 months payback; the financials $467K, $1.59M and $2.99M of revenue with breakeven in month 29 (May 2029) and an $82.8K peak monthly burn; the ask $600K (40%) product and engineering, $450K (30%) city launches, $300K (20%) marketing, $150K (10%) operations and insurance. The lint is clean: the longest slide has 33 words.

Rules

• No slide promises funding, returns or a valuation. The financials slide says the projections are the founder's own assumptions, not a forecast. Not investment advice.
• Every number on a slide comes from a file. Change numbers at their source.
• Real people on the team slide, with their real roles.
• The deck file loads nothing from the internet: it works offline and in any inbox preview.
