# Send Cabin Sol 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": "cabin-sol", "name": "Cabin Sol", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/sp0oby/cabin-sol", "canonicalUrl": "https://clawhub.ai/sp0oby/cabin-sol", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/cabin-sol", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=cabin-sol", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "CLAUDE.md", "README.md", "SKILL.md", "data/addresses/programs.json", "knowledge/challenges/00-hello-solana.md", "knowledge/challenges/01-spl-token.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "cabin-sol", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-01T05:40:52.418Z", "expiresAt": "2026-05-08T05:40:52.418Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=cabin-sol", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=cabin-sol", "contentDisposition": "attachment; filename=\"cabin-sol-1.2.1.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "cabin-sol" }, "scope": "item", "summary": "Item download looks usable.", "detail": "Yavira can redirect you to the upstream package for this item.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/cabin-sol" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/cabin-sol", "downloadUrl": "https://openagent3.xyz/downloads/cabin-sol", "agentUrl": "https://openagent3.xyz/skills/cabin-sol/agent", "manifestUrl": "https://openagent3.xyz/skills/cabin-sol/agent.json", "briefUrl": "https://openagent3.xyz/skills/cabin-sol/agent.md" } } ``` ## Documentation ### Cabin Sol 🌲 "Return to primitive computing." A comprehensive Solana development guide for AI agents. Build programs with Anchor, master the account model, and avoid the gotchas that wreck most developers. ### THE MOST IMPORTANT CONCEPT ACCOUNTS ARE EVERYTHING ON SOLANA. Unlike Ethereum where contracts have internal storage, Solana programs are stateless. All data lives in accounts that programs read and write. For EVERY feature, ask: Where does this data live? (which account) Who owns that account? (program-owned vs user-owned) Is it a PDA? (Program Derived Address - no private key) Who pays rent? (rent-exempt = 2 years upfront) ### Teaching Mode "How do PDAs work?" "Explain the Solana account model" "What's the difference between SPL Token and Token-2022?" ### Build Mode "Help me build a staking program" "Create an NFT collection with Metaplex" "Build a token swap" ### Review Mode "Review this program for vulnerabilities" "Check my PDA derivation" "Audit this CPI" ### Debug Mode "Why is my transaction failing?" "Debug this 'account not found' error" "Fix my token transfer" ### Option A: create-solana-dapp (Recommended) npx create-solana-dapp@latest # Select: Next.js + next-tailwind-counter cd my-project npm install npm run anchor localnet # Terminal 1 npm run anchor build && npm run anchor deploy # Terminal 2 npm run dev # Terminal 3 ### Option B: Pure Anchor anchor init my_program cd my_program solana-test-validator # Terminal 1 anchor build && anchor deploy # Terminal 2 anchor test ### PROJECT STRUCTURE my-solana-dapp/ ├── anchor/ # Solana programs (Rust) │ ├── programs/ │ │ └── my_program/ │ │ └── src/lib.rs # Your Rust program │ ├── tests/ # TypeScript tests │ └── Anchor.toml # Anchor config ├── src/ # Next.js frontend │ ├── app/ │ └── components/ └── package.json ### CHALLENGES Learn Solana through progressive challenges: #ChallengeCore Concept0Hello SolanaFirst Anchor program, accounts1SPL TokenFungible tokens, ATAs, minting2NFT MetaplexNFT standard, metadata, collections3PDA EscrowPDAs, program authority, escrow4StakingTime-based rewards, deposits5Token-2022Transfer hooks, extensions6Compressed NFTsState compression, Merkle trees7Oracle (Pyth)Price feeds, staleness checks8AMM SwapConstant product, liquidity pools9Blinks & ActionsShareable transactions ### Ownership (The Hard Part) // Each value has ONE owner let s1 = String::from("hello"); let s2 = s1; // s1 MOVED to s2 // println!("{}", s1); // ERROR! // Borrowing lets you use without owning fn get_length(s: &String) -> usize { s.len() // Borrow, don't own } ### Result & Option // Result for errors pub fn do_thing(ctx: Context) -> Result<()> { let value = some_operation().ok_or(ErrorCode::Failed)?; Ok(()) } // Option for nullable let maybe: Option = Some(42); let value = maybe.unwrap_or(0); // Safe default ### Program Structure use anchor_lang::prelude::*; declare_id!("YourProgramId11111111111111111111111111111"); #[program] pub mod my_program { use super::*; pub fn initialize(ctx: Context, data: u64) -> Result<()> { ctx.accounts.my_account.data = data; ctx.accounts.my_account.authority = ctx.accounts.authority.key(); Ok(()) } } #[derive(Accounts)] pub struct Initialize<'info> { #[account( init, payer = authority, space = 8 + 8 + 32, // discriminator + u64 + Pubkey )] pub my_account: Account<'info, MyAccount>, #[account(mut)] pub authority: Signer<'info>, pub system_program: Program<'info, System>, } #[account] pub struct MyAccount { pub data: u64, pub authority: Pubkey, } ### Account Constraints Cheatsheet // Initialize new account #[account(init, payer = payer, space = 8 + SIZE)] pub new_account: Account<'info, Data>, // Mutable existing #[account(mut)] pub existing: Account<'info, Data>, // Verify ownership #[account(has_one = authority)] pub owned: Account<'info, Data>, // PDA with seeds #[account( seeds = [b"vault", user.key().as_ref()], bump, )] pub vault: Account<'info, Vault>, // Initialize PDA #[account( init, payer = user, space = 8 + 64, seeds = [b"user", user.key().as_ref()], bump, )] pub user_data: Account<'info, UserData>, // Close and reclaim rent #[account(mut, close = recipient)] pub closing: Account<'info, Data>, ### PDAs (Program Derived Addresses) // PDAs are deterministic addresses with no private key // Your program can "sign" for them // Find PDA let (pda, bump) = Pubkey::find_program_address( &[b"vault", user.key().as_ref()], &program_id, ); // Sign with PDA in CPI let seeds = &[b"vault", user.key().as_ref(), &[bump]]; let signer = &[&seeds[..]]; token::transfer( CpiContext::new_with_signer( ctx.accounts.token_program.to_account_info(), Transfer { from, to, authority: vault }, signer, ), amount, )?; ### 1. Account Model ≠ EVM Storage Programs are stateless. ALL data lives in accounts. ### 2. PDAs Have No Private Key Derived deterministically from seeds. Only the program can sign. ### 3. Token Accounts Are Separate Each token needs its own account per wallet (Associated Token Account). ### 4. Rent Must Be Paid Accounts need SOL to exist. Rent-exempt = 2 years upfront (~0.002 SOL). ### 5. Compute Units ≠ Gas Fixed budget: 200k default, 1.4M max. Request more if needed. ### 6. Space Includes Discriminator ALWAYS add 8 bytes for Anchor's discriminator! // WRONG space = 8 + 32 // Forgot discriminator? NO! // RIGHT space = 8 + 8 + 32 // 8 (discriminator) + 8 (u64) + 32 (Pubkey) ### 7. Integer Overflow // BAD let result = a + b; // Can panic! // GOOD let result = a.checked_add(b).ok_or(ErrorCode::Overflow)?; ### 8. Token-2022 Is Different Separate program ID from SPL Token! Check which one you're using. ### Wallet Connection // Already configured in create-solana-dapp! import { useWallet, useConnection } from '@solana/wallet-adapter-react'; import { WalletMultiButton } from '@solana/wallet-adapter-react-ui'; function App() { const { publicKey } = useWallet(); return ( <> {publicKey &&
