What is knowmint CLAUDE.md?

Project instructions for KnowMint, a knowledge marketplace where people sell experience and AI agents can discover and pay for it using Solana and the x402 payment protocol. They describe the project, its interfaces, architecture, and development commands.

Building, testing, linting, deploying, or using KnowMint's web interface, command-line tool, REST API, or MCP server.

They give a coding agent the project-specific context needed to work consistently in the repository.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01623	$0.01623
Opus 5.5	$0.00649	$0.00649
Sonnet 5.5	$0.00325	$0.00325
Haiku 4.5	$0.00162	$0.00162

Measured 2mo ago against content hash 3121b163cad2, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

knowmint CLAUDE.md 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 2mo 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.

Project Overview

KnowMint — AIエージェントが x402 プロトコルで SOL を直接自律支払いできる、初のナレッジマーケットプレイス。人間が体験知・暗黙知を出品 → エージェントが自律発見・直接支払い（秘密鍵は運営非保有）。 AIエージェントを活用した知識調達にも対応（エージェント提案 → 人間承認 → 作業再開）。仮想通貨 (Solana / x402) で決済。3つのアクセスレイヤー: Web UI / CLI (km) / REST API+MCP。

Commands

npm run dev              # 開発サーバー (localhost:3000)
npm run build            # プロダクションビルド
npm run lint             # ESLint

Architecture

Next.js 16 App Router + Supabase + Solana 決済。詳細は @docs/architecture.md 参照。

Supabase クライアント使い分け (重要)

クライアント	ファイル	用途	RLS
Browser	`lib/supabase/client.ts`	クライアントコンポーネント	適用
Server	`lib/supabase/server.ts`	RSC, Server Actions	適用
Admin	`lib/supabase/admin.ts`	API routes のみ	バイパス

API routes は Admin クライアントで RLS をバイパスし、withApiAuth 内で手動認可する。

API Route パターン

ほとんどの route は withApiAuth HOC + getAdminClient() + apiSuccess()/apiError() を使用。 /api/v1/keys は例外 (独自認証)。認証フロー: IP rate limit → APIキー(SHA-256) → パーミッション → キー別 rate limit

コンテンツ分離 (セキュリティ)

knowledge_items — 公開情報 + preview_content
knowledge_item_contents — 購入者のみアクセス可 (RLS で保護)

Environment Variables

必須: NEXT_PUBLIC_SUPABASE_URL / NEXT_PUBLIC_SUPABASE_ANON_KEY / SUPABASE_SERVICE_ROLE_KEY

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
