## When to use
Use this skill when you are:
- Building a strategy that screens pools/vault-like opportunities (APY/TVL)
- Resolving token identifiers/decimals/chain for correct unit handling
- Fetching wallet balances (API or on-chain) and recording results to the local ledger
## How to use
- [rules/pools.md](rules/pools.md) - Pool discovery, APY/TVL, DefiLlama merges
- [rules/tokens.md](rules/tokens.md) - Token metadata, decimals, gas token lookup
- [rules/balances-and-ledger.md](rules/balances-and-ledger.md) - Balance reads and local ledger bookkeeping
