idea-sprint

idea-sprint is a skill for Claude Code from solanabr/solana-ai-kit. It costs 58 tokens per session (1,428 once invoked), scanned A, original, MIT.

A structured process for deciding what to build in crypto, meaning software that uses blockchain networks or digital assets. It questions the idea, checks whether blockchain is genuinely needed, compares exactly three candidates, and ends with a go-or-no-go decision.

In plain words
What is it for?
For choosing and testing crypto startup or project ideas, recording the decision and evidence, and handing the result to later work such as a pitch deck or hackathon build.
Why use it?
It replaces vague brainstorming with blunt validation, exposing weak ideas, unclear target users, constraints, and risks before coding starts.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Hidden instructions were detected in comments or invisible text. These could contain malicious directives. Manual review is recommended.
    Fix: Audit all comments and invisible characters. Remove any instructions that direct the agent to perform unauthorized actions. Use plain, reviewable content.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

idea-sprint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.md and .claude/context/build.md if present — resume from prior state instead of re-interviewing.
  • On completion: write/update .claude/context/idea.md with 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):
