What it does

Startupblueprint is an agent skill from buildfastwithai/gen-ai-experiments. Turn a startup, SaaS, app, developer tool, website, repository, or product idea into an evidence-backed business plan, monetization strategy, pricing architecture, editable 12-month financial model, and 90-day execution roadmap. Use when Codex needs to analyze how a startup can become a sustainable business; decide free versus paid, monthly, annual, usage-based, one-time, or lifetime pricing; design tiers and upgrade triggers; estimate unit economics and break-even under explicit assumptions; compare scenarios…

Its SKILL.md is about 2.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/analysis-schema.md` and `references/financial-model.md`).

It sits in Business, Finance & HR, covering Financial modeling, Startup and business strategy and Excel spreadsheets. It works with Microsoft Excel. The repository describes itself as: Collection of Jupyter notebooks is designed to provide you with a comprehensive guide to various AI tools and technologies. The licence is MIT.

When your agent uses it

  • Codex needs to analyze how a startup can become a sustainable business
  • Decide free versus paid
  • Lifetime pricing
  • Design tiers and upgrade triggers

Example prompts

  • “/startupblueprint”

Requirements

  • Python 3
  • Node.js

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Understand the startup
  2. Research the market and business model
  3. Design monetization and pricing
  4. Build the financial inputs
  5. Validate and score the plan
  6. Generate the HTML business report and roadmap
  7. Generate the editable financial model
  8. Deliver the result

What it can do on your machine

Read from SKILL.md and the folder at commit 7b62043. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (Python and JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • python3
    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Startupblueprint loads about 2.2k tokens when it runs, and up to ~6.1k if it reads all its reference files. Until then it costs about 163 tokens; SKILL.md has 941 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~163
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~6.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Turn a startup, SaaS, app, developer tool, website, repository, or product idea into an evidence-backed business plan, monetization strategy, pricing architecture, editable 12-month financial model, and 90-day execution roadmap. Use when Codex needs to analyze how a startup can become a sustainable business; decide free versus paid, monthly, annual, usage-based, one-time, or lifetime pricing; design tiers and upgrade triggers; estimate unit economics and break-even under explicit assumptions; compare scenarios; or produce a native Markdown business plan, formula-driven Excel workbook, and CSV roadmap from a URL or description.

StartupBlueprint

Turn a startup URL, repository, or description into a decision-ready plan for how the product can acquire customers, charge, cover its costs, and reach a testable first version of sustainability.

Read references/research-playbook.md before researching. Read references/analysis-schema.md before creating the analysis JSON. Read references/financial-model.md before generating the workbook.

Resolve SKILL_DIR as the directory containing this SKILL.md. Run bundled scripts from SKILL_DIR. Write deliverables into the user's current workspace, normally under outputs/.

Workflow

1. Understand the startup
  • Inspect the supplied URL, repository, landing page, pricing page, README, screenshots, or description.
  • Identify the product, stage, geography, currency, primary user, economic buyer, painful job, promised outcome, delivery model, current free or paid offer, and founder's immediate objective.
  • Distinguish verified product facts, public market evidence, user-supplied numbers, working assumptions, and unknowns.
  • Ask one concise question only when the answer changes the economic model materially and cannot be represented safely as an editable assumption. Otherwise continue and label assumptions.
  • Never inspect private analytics, billing, customer, or financial data unless the user explicitly supplies or authorizes it.
2. Research the market and business model
  • Use current public evidence. Prefer official product, pricing, documentation, terms, and company pages.
  • Research the current prices and packaging of at least three relevant competitors or substitutes in standard mode; aim for five to eight when the category supports it.
  • Identify the most plausible customer segment, economic buyer, distribution channels, value metric, revenue streams, cost drivers, and defensible advantage.
  • Treat competitor pricing as an anchor, not proof of willingness to pay.
  • Link every material competitor price and market claim to a direct source with a checked date.
  • Define a narrow initial ICP, buying trigger, qualification signals, anti-ICP, positioning, and the cheapest reachable distribution wedge.
  • Build TAM, SAM, and a realistic 24-month SOM bottom-up only when eligible account counts and annual revenue per account are sourced or visibly labeled assumptions. Otherwise keep the values unknown and show the missing formula inputs.
3. Design monetization and pricing
  • Compare at least four plausible monetization models. Always evaluate a recurring model and explicitly decide whether one-time or lifetime access is safe.
  • Choose one primary model and one credible alternative to validate.
  • Propose concrete tiers with target segment, monthly-equivalent price hypothesis, limits, included value, upgrade trigger, and expected paid-customer mix.
  • Make free versus trial, annual discount, usage overage, and lifetime decisions explicit.
  • Reject uncapped lifetime access when meaningful hosting, API, inference, data, support, or storage costs continue.
  • Present prices as hypotheses until supported by transaction or customer evidence.
4. Build the financial inputs
  • Capture opening free and paid users, monthly acquisition, free-to-paid conversion, direct paid acquisition, churn, variable costs, fixed costs, acquisition spend, setup revenue, and starting cash.
  • Store every input as {value, status, confidence, basis, source_url} using the schema. Use status: user, public, assumption, or unknown.
  • Never invent a hidden number. For a missing input, either use null with unknown or create a visible, conservative assumption and explain its basis.
  • Create conservative, base, and optimistic scenarios by changing explicit drivers rather than pasting desired outputs.
5. Validate and score the plan

Write outputs/startupblueprint-analysis.json, then run:

bash
python3 "$SKILL_DIR/scripts/prepare_plan.py" \
  outputs/startupblueprint-analysis.json \
  outputs/startupblueprint-prepared.json

The script validates evidence, ICP, market sizing, positioning, go-to-market, pricing mix, financial inputs, scenario coverage, and roadmap coverage; computes a deterministic readiness score and 12-month preview; assigns EVIDENCE_BACKED, PROVISIONAL, or INSUFFICIENT_DATA; and returns HEALTHY, FRAGILE, UNSUSTAINABLE, or INSUFFICIENT_DATA. Do not manually override its score, status, or verdict.

6. Generate the HTML business report and roadmap

Run:

bash
python3 "$SKILL_DIR/scripts/generate_startupblueprint_report.py" \
  outputs/startupblueprint-prepared.json \
  outputs/startupblueprint-report.html \
  --csv outputs/startupblueprint-90-day-roadmap.csv

The HTML file is the visual business report. The CSV is the operating roadmap, with an objective, action, deliverable, metric, and decision rule for every 90-day phase.

7. Generate the editable financial model
  • Use the Codex spreadsheet runtime and @oai/artifact-tool; do not substitute another workbook library.
  • Load the bundled workspace dependencies, create a node_modules symlink in a writable working directory pointing to the provided Node packages, and use the provided Node executable.
  • Run:
bash
node "$SKILL_DIR/scripts/generate_financial_model.mjs" \
  outputs/startupblueprint-prepared.json \
  outputs/startupblueprint-financial-model.xlsx \
  --preview-dir outputs/startupblueprint-financial-model-preview
  • Verify every sheet visually, inspect representative formulas, scan formula errors, and keep the generated previews only as QA support.
  • Treat blue-font cells as editable inputs, black as formulas, green as links to another sheet, and yellow fill as an assumption or missing input requiring attention.
8. Deliver the result

Return clickable absolute links to:

  • startupblueprint-report.html — visual strategy report with business model, pricing decision, risks, evidence, scenarios, and roadmap.
  • startupblueprint-financial-model.xlsx — editable inputs, pricing, unit economics, scenarios, 12-month forecast, dashboard charts, sources, and checks.
  • startupblueprint-90-day-roadmap.csv — execution sequence and evidence gates for days 1–90.

Summarize the recommended business model, base price hypothesis, readiness score, first go-to-market channel, financial verdict, break-even estimate, and largest unverified assumption. If the result is INSUFFICIENT_DATA, say which exact inputs must be measured before using the forecast.

Modes

  • quick — Use available evidence, up to three comparables, provisional assumptions, and a compact plan.
  • standard — Use three to eight comparables, four monetization models, all three scenarios, and the complete deliverables. Use by default.
  • deep — Add broader competitors, channel evidence, contradiction checks, and more granular costs.
  • pre-revenue — Focus on monetizing a free product with no historical revenue or conversion data.
  • audit — Evaluate an existing business model, pricing structure, and economics before proposing changes.

Safety and quality bar

  • Never claim guaranteed demand, conversion, profitability, product-market fit, funding, or growth.
  • Never hide invented CAC, churn, conversion, costs, margin, or customer volume inside the model.
  • Never label competitor pricing as willingness-to-pay evidence.
  • Never invent market size, eligible accounts, customer pain, willingness to pay, testimonials, partnerships, or competitor capabilities.
  • Never recommend uncapped lifetime access against ongoing variable or support costs.
  • Never change live prices, billing, checkout, product limits, customer subscriptions, ads, or outbound campaigns automatically.
  • Keep taxes, payment fees, refunds, contracts, migrations, and regional pricing visible as limitations when relevant.
  • Prefer a reversible 90-day test plan over false precision.
