Idea Sprint
Validate crypto startup ideas and decide whether they're worth building.
Installation
- Make sure Claude is on your device and in your terminal.
Skills load from
~/.claude/skills/when Claude Code starts up — so you need it on your machine first. If you don't have it yet, install it once with the command below, then runclaudein any terminal to verify.One-time setupnpm i -g @anthropic-ai/claude-codeAlready have it? Skip ahead.
- Paste into Claude Code or into your terminal.
This copies the whole skill folder into
~/.claude/skills/idea-sprint-solanabr/— the SKILL.md plus any scripts, reference docs, or templates the skill ships with. Safe default: works for every skill.Faster alternative (instruction-only skills)
Skips the clone and grabs only the SKILL.md file. Don't use this if the skill ships Python scripts, reference markdowns, or asset templates — they won't be downloaded and the skill will fail when it tries to load them.
Quick install (SKILL.md only)Sign up to copy - Restart Claude Code.
Quit and reopen Claude Code (or any other agent that loads from
~/.claude/skills/). New skills are picked up on startup. - Just ask Claude.
Skills auto-activate when your request matches the skill's description — no slash command needed. Trigger phrases live in the skill's own frontmatter; you can read them in the “What this skill does” section above.
Prefer to read the source first? Open on GitHub.
When Claude uses it
Find and validate what to build in crypto. Use when the user asks "what should I build", "validate this idea", "is this worth building", "find me a startup idea", "crypto idea", or wants blunt feedback on a project concept before writing code.
What this skill does
Idea Sprint
Interview → necessity gate → 3 candidates → score → go/no-go. Output is a decision, not a brainstorm.
Context handoff
- At start: read
.claude/context/idea.mdand.claude/context/build.mdif present — resume from prior state instead of re-interviewing. - On completion: write/update
.claude/context/idea.mdwith the chosen idea, scores, validation evidence, and open risks. Downstream skills (pitch-deck, hackathon) read it.
Workflow
1. Blunt interview
No flattery. Short, pointed questions, one at a time, until three things are explicit:
- Edge — what the founder knows/can do that most can't (domain, distribution, tech)
- Constraint — time, money, team, chain commitments
- Wedge — the niche entry point, not the end-state vision
Push back on vague answers. "DeFi for everyone" is not a wedge. Full question bank: interview-framework.md.
2. Crypto-necessity gate
Kill question: "What gets worse if I remove the blockchain?" If the answer is vague, aesthetic, or marketing-driven — redirect the idea before scoring it. Pass criteria and redirect patterns: crypto-necessity-test.md.
3. Exactly 3 candidates
Generate three diverse candidates (different mechanisms/markets, not three flavors of one idea). For each:
- One-line pitch + target user
- Winner case — what's true in 18 months if it works
- Bear case — the most likely way it dies
Seed from datasets + live landscape (below), then combine with fresh research. Datasets are inspiration, not constraints.
4. Score /15
Each candidate, 0–3 per dimension (full anchors: scoring-rubric.md):
| Dimension | 3 means |
|---|---|
| Founder fit | unfair advantage |
| MVP speed | shippable in under a week |
| Distribution | first ten users are obvious |
| Market pull | people already paying for bad alternatives |
| Revenue path | clear monetization story |
5. Validate + go/no-go
Check demand signals against customer-signal-rubric.md — manual workarounds, active forks, bounties, on-chain activity = real; likes and "cool idea" replies = noise. Sprint structure: validation-framework.md.
- ≥ 8/15 → go. Write
idea.md, suggest/scaffoldnext. - 6–7 → conditional: name the one dimension to de-risk first.
- < 6 → strong no-go. Every no-go gets a pivot suggestion — use pivot-or-persist.md.
6. Write .claude/context/idea.md
Chosen idea, wedge, scores table, demand evidence, bear case, next step.
Idea datasets (inert JSON, ~515 entries)
In ../ext/solana-new/skills/data/ideas/:
- web3-ideas-combined.json — master list (summary)
- a16z-big-ideas-2025.json, a16z-state-of-crypto-2025.json
- yc-requests-for-startups.json, yc-crypto-companies.json
- alliance-ideas.json, superteam-ideas.json
- rwa-defi-2026-ideas.json, yash-defi-2024-ideas.json
Idea-source guides (markdown commentary on the same sources): ../ext/solana-new/skills/data/guides/ — plus source-map.md and research-playbook.md for where/how to research live.
Live hackathon landscape
ext/colosseum — 5,400+ Colosseum submissions for crowdedness checks, winner patterns, and gap analysis (requires COLOSSEUM_COPILOT_PAT).
Output format
Report spec (3 ranked candidates, scores, decision): output-spec.md.
