Name: skills (Claude Skill)
Author: sendaifun

A public marketplace of Solana-related skills from Sendai — teach Claude on-chain Solana development patterns.

sendaifun/skills is a community marketplace of Agent Skills focused on Solana: SPL tokens, Anchor programs, common transactions, wallet integration patterns, and recipes for on-chain automations. It's opinionated toward Sendai's tooling but the patterns work broadly. Dev-focused — does not provide key management or wallet drainers.

なぜ使うのか

主な機能

Solana development idioms: Anchor, SPL, transaction construction
TypeScript tooling; web3.js and @solana/spl-token patterns
Recipes for common flows: mint, transfer, swap, stake
Open marketplace — anyone can contribute a skill
Sendai Agent Kit-adjacent but not tied to it

ユースケース

実用的な使い方： skills

How to scaffold an Anchor program with Claude

👤 Solana developers starting a new on-chain program ⏱ ~60 min advanced

使うタイミング： You need a new Anchor program and don't want to pattern-match from random GitHub repos.

フロー

State the program goal

Scaffold an Anchor program for a simple escrow: deposit SOL, release to seller on confirmation.✓ コピーしました

→ Program with accounts, instructions, and idiomatic Anchor attributes
Tests

Add TypeScript client tests using the Anchor test harness.✓ コピーしました

→ tests/ directory with typed client
Build and deploy to localnet

Build, deploy to localnet, and verify the escrow flow with a test transaction.✓ コピーしました

→ Successful local deploy

結果： A working Anchor program with tests.

注意点

Missing account constraints — Insist on explicit constraints for every account; skill prompts Claude to enumerate them

組み合わせ： filesystem

Mint and distribute an SPL token

👤 Builders launching a token for a dev/test use case ⏱ ~30 min intermediate

使うタイミング： You need an SPL token script you actually trust.

フロー

Draft the mint script

Write a TypeScript script that creates an SPL token with 9 decimals and mints 1M to a treasury account.✓ コピーしました

→ Script using @solana/spl-token with proper PDAs
Airdrop helper

Add a function that airdrops to an array of recipients using associated token accounts.✓ コピーしました

→ ATA creation + transfer

結果： A reusable mint + distribute script.

注意点

Forgetting ATA creation — Use getOrCreateAssociatedTokenAccount, not manual derivations

組み合わせ

他のMCPと組み合わせて10倍の力を

skills-skill-5 + filesystem

Work across an Anchor monorepo

Read programs/, add a new program following the existing structure.✓ コピーしました

skills-skill-5 + github

Open PRs for contract changes with meaningful descriptions

Open a PR titled 'feat: escrow program' with tests.✓ コピーしました

コストと制限

運用コスト

APIクォータ: none beyond RPC usage you configure
呼び出しあたりのトークン: 5–15k per scaffold
金額: free at skill level; Solana fees are your own
ヒント: Develop on localnet/devnet; don't burn mainnet SOL for iteration

セキュリティ

権限、シークレット、影響範囲

認証情報の保管： never paste private keys into the prompt — use env vars and ephemeral devnet keys

データ送信先： your configured RPC only

絶対に付与しない： wallet signing from within a prompt

On-chain code is bearer-asset code: treat security review as mandatory before mainnet
Never ask the skill to work with a mainnet wallet that holds real value

トラブルシューティング

よくあるエラーと対処法

anchor build fails

Check Rust toolchain and Anchor CLI version; pin with rust-toolchain.toml.

確認： anchor --version && rustc --version

Account constraint errors at runtime

Re-ask Claude to enumerate constraints and PDAs explicitly
