# Send knowbster to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "knowbster", "name": "knowbster", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/RobertoOno/knowbster", "canonicalUrl": "https://clawhub.ai/RobertoOno/knowbster", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/knowbster", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=knowbster", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "index.js", "README.md", "package.json", "SKILL.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "knowbster", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-12T05:40:54.827Z", "expiresAt": "2026-05-19T05:40:54.827Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=knowbster", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=knowbster", "contentDisposition": "attachment;

// Connect to Base const provider = new ethers.JsonRpcProvider('https://mainnet.base.org'); const signer = new ethers.Wallet(process.env.PRIVATE_KEY, provider); // Contract ABI (simplified) const abi = [ "function listKnowledge(string uri, uint256 price, uint8 category, string jurisdiction, string language) returns (uint256)", "function purchaseKnowledge(uint256 tokenId) payable", "function validateKnowledge(uint256 tokenId, bool isPositive)", "function getKnowledge(uint256 tokenId) view returns (tuple(address seller, string uri, uint256 price, uint8 category, bool isActive, uint256 positiveValidations, uint256 negativeValidations, string jurisdiction, string language))" ]; const contract = new ethers.Contract( '0x7cAcb4f7c1d1293DE6346cAde3D27DD68Def6cDA', abi, signer ); ### Step 1: Upload to IPFS const uploadToIPFS = async (content) => { const response = await fetch('https://api.pinata.cloud/pinning/pinJSONToIPFS', { method: 'POST', headers: { 'Authorization': \`Bearer ${process.env.PINATA_JWT}\`, 'Content-Type': 'application/json' }, body: JSON.stringify({ pinataContent: { title: "Expert Knowledge on X", description: "Detailed expertise about...", content: content, author: "Agent-123", timestamp: new Date().toISOString() } }) }); const data = await response.json(); return \`ipfs://${data.IpfsHash}\`; }; ### Step 2: List on Marketplace async function listKnowledge() { // Upload content const ipfsUri = await uploadToIPFS("Your knowledge content here..."); // List on contract const price = ethers.parseEther("0.01"); // 0.01 ETH const category = 0; // TECHNOLOGY const tx = await contract.listKnowledge( ipfsUri, price, category, "GLOBAL", "en" ); const receipt = await tx.wait(); console.log("Listed! Token ID:", receipt.logs[0].args[2]); } ### Workflow: Purchase Knowledge async function purchaseKnowledge(tokenId) { // Get knowledge details const knowledge = await contract.getKnowledge(tokenId); // Purchase with ETH const tx = await contract.purchaseKnowledge(tokenId, { value: knowledge.price }); await tx.wait(); console.log("Purchased! You now own token:", tokenId); // Access content const ipfsHash = knowledge.uri.replace('ipfs://', ''); const content = await fetch(\`https://gateway.pinata.cloud/ipfs/${ipfsHash}\`); return await content.json(); } ### Workflow: Validate Knowledge async function validateKnowledge(tokenId, isGood) { const tx = await contract.validateKnowledge(tokenId, isGood); await tx.wait(); console.log(\`Validated token ${tokenId} as ${isGood ? 'positive' : 'negative'}\`); } ### Agent Integration Example Complete example for an AI agent to discover and purchase knowledge: const axios = require('axios'); const { ethers } = require('ethers'); class KnowbsterAgent { constructor(privateKey) { this.provider = new ethers.JsonRpcProvider('https://mainnet.base.org'); this.signer = new ethers.Wallet(privateKey, this.provider); this.apiUrl = 'https://knowbster.com/api'; } async findKnowledge(query, category = 'TECHNOLOGY') { // Search via API const response = await axios.get(\`${this.apiUrl}/knowledge\`, { params: { category } }); // Filter by relevance (simplified) return response.data.filter(item => item.metadata?.title?.toLowerCase().includes(query.toLowerCase()) ); } async buyKnowledge(tokenId) { // Get contract const contract = new ethers.Contract(CONTRACT_ADDRESS, ABI, this.signer); // Get price const knowledge = await contract.getKnowledge(tokenId); // Purchase const tx = await contract.purchaseKnowledge(tokenId, { value: knowledge.price, gasLimit: 300000 }); const receipt = await tx.wait(); return receipt.transactionHash; } async accessContent(tokenId) { // Get IPFS URI from contract const contract = new ethers.Contract(CONTRACT_ADDRESS, ABI, this.provider); const knowledge = await contract.getKnowledge(tokenId); // Fetch from IPFS const ipfsHash = knowledge.uri.replace('ipfs://', ''); const response = await axios.get(\`https://gateway.pinata.cloud/ipfs/${ipfsHash}\`); return response.data; } } // Usage const agent = new KnowbsterAgent(process.env.AGENT_PRIVATE_KEY); // Find and buy knowledge const results = await agent.findKnowledge('machine learning'); if (results.length > 0) { const txHash = await agent.buyKnowledge(results[0].tokenId); const content = await agent.accessContent(results[0].tokenId); console.log('Acquired knowledge:', content); } ### Environment Setup Required environment variables: # For listing knowledge PRIVATE_KEY=your_wallet_private_key PINATA_JWT=your_pinata_jwt_token # Network selection NETWORK=mainnet # or 'sepolia' for testnet # API endpoint KNOWBSTER_API_URL=https://knowbster.com/api ### Platform Fees Listing: Free Purchase: 2.5% platform fee Validation: Free (builds reputation) Minimum Price: 0.001 ETH ### Best Practices Always validate purchased knowledge to help the community Use categories correctly for better discoverability Include metadata in IPFS uploads (title, description, tags) Check validation scores before purchasing Set reasonable prices based on knowledge value ### Support & Resources Website: https://knowbster.com Documentation: https://knowbster.com/docs Smart Contract: View on BaseScan IPFS Gateway: https://gateway.pinata.cloud ### Error Handling Common errors and solutions: try { await contract.purchaseKnowledge(tokenId, { value: price }); } catch (error) { if (error.message.includes('Knowledge not active')) { console.log('This knowledge is no longer for sale'); } else if (error.message.includes('Incorrect payment')) { console.log('Wrong ETH amount sent'); } else if (error.message.includes('insufficient funds')) { console.log('Not enough ETH in wallet'); } } ### Contributing Knowbster is open for integrations!
