New install
I tried to install a skill package from Yavira, but the item currently does not return a direct package file. Inspect the source page and any extracted docs, then tell me what you can confirm and any manual steps still required. Then review README.md for any prerequisites, environment setup, or post-install checks.
Upgrade existing
I tried to upgrade a skill package from Yavira, but the item currently does not return a direct package file. Compare the source page and any extracted docs with my current installation, then summarize what changed and what manual follow-up I still need. Then review README.md for any prerequisites, environment setup, or post-install checks.

Cabin Sol ๐ฒ
"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

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<DoThing>) -> Result<()> { let value = some_operation().ok_or(ErrorCode::Failed)?; Ok(()) } // Option for nullable let maybe: Option<u64> = 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<Initialize>, 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 โ 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 โ 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 ( <> <WalletMultiButton /> {publicKey && <p>Connected: {publicKey.toBase58()}</p>} </> ); }
Calling Programs
import { Program, AnchorProvider, BN } from '@coral-xyz/anchor'; const program = new Program(idl, provider); // Write await program.methods .initialize(new BN(42)) .accounts({ myAccount: keypair.publicKey, authority: wallet.publicKey, systemProgram: SystemProgram.programId, }) .signers([keypair]) .rpc(); // Read const account = await program.account.myAccount.fetch(pubkey); console.log(account.data.toNumber());
SPL Token (Original)
spl-token create-token spl-token create-account <MINT> spl-token mint <MINT> 1000
Token-2022 (New)
Extensions: transfer hooks, confidential transfers, interest-bearing, non-transferable. spl-token create-token --program-id TokenzQdBNbLqP5VEhdkAS6EPFLC1PHnBqCXEpPxuEb
Metaplex NFTs
Standard NFT metadata, collections, royalties.
Compressed NFTs
Merkle tree storage. 1M NFTs for ~$100 instead of $1M.
TESTING
import * as anchor from '@coral-xyz/anchor'; import { expect } from 'chai'; describe('my-program', () => { const provider = anchor.AnchorProvider.env(); anchor.setProvider(provider); const program = anchor.workspace.MyProgram; it('initializes', async () => { const account = anchor.web3.Keypair.generate(); await program.methods .initialize(new anchor.BN(42)) .accounts({ myAccount: account.publicKey }) .signers([account]) .rpc(); const data = await program.account.myAccount.fetch(account.publicKey); expect(data.data.toNumber()).to.equal(42); }); });
DEPLOYMENT

SECURITY CHECKLIST
All signers verified PDA bumps stored and validated Integer overflow handled (checked math) Account space includes discriminator Rent exemption considered Close sends rent to correct recipient CPI signer seeds correct Program IDs validated in CPIs
