Architecture guide for building DeFi protocols on the Flow blockchain. Covers Flow's DeFi-specific advantages (MEV-free EVM, cross-VM atomic transactions, on-chain automation), core DeFi primitives (lending health factors, interest rate kink models, AMM type selection), liquidity bootstrapping strategy (veFLOW, Merkl, CL ranges, bootstrapping benchmarks), and the current Flow DeFi ecosystem map (existing protocols, missing primitives, opportunity analysis). TRIGGER when: designing a lending protocol on Flow, choosing AMM type for a DEX, liquidity bootstrapping strategy, veFLOW mechanics, "how does Flow DeFi work", "AMM types on Flow", "liquidity bootstrapping", "Flow DeFi ecosystem", "cross-VM composability for DeFi", "health factors", "interest rate curves", "collateral design", "DEX TVL", "Merkl integration", "missing DeFi primitives on Flow", "perp DEX on Flow", "launchpad on Flow", "COA pattern", "MEV-free EVM".

flow-ecosystem

onflow/flow-ai-tools

Use when a developer is building, analyzing, or shipping on Flow (Cadence or Flow EVM) and needs an ecosystem tool: on-chain analytics, metrics, a query, or a dashboard (Dune); a Flow EVM RPC endpoint, node access, or reading chain state from an app (Alchemy); or swapping tokens, adding liquidity, getting a price quote, or integrating a DEX (PunchSwap / KittyPunch). Routes the builder to the right Flow ecosystem integration and supplies how to call it (MCP server, docs, or on-chain contract). Triggers on requests like "building on Flow and need a tool for X", "how do I get Flow on-chain data or a dashboard", "what should I use to query Flow", "Flow EVM RPC or node provider", "how do I swap or add liquidity on Flow", "integrate a DEX on Flow", or "is there a Flow tool for X". Not for non-Flow chains, and not for Cadence language correctness.

cadence-lang

onflow/flow-ai-tools

Comprehensive guide for writing correct, secure, and idiomatic Cadence smart contract code on the Flow blockchain. Covers language fundamentals (resources, contracts, transactions, interfaces, accounts, references, imports), access control and entitlements, capabilities, pre/post conditions, security best practices, anti-patterns to avoid, and proven design patterns. TRIGGER when: writing or debugging Cadence code, asking about Cadence syntax, access(self), access(all), entitlements, resources, move operator (<-), capabilities, references, pre/post conditions, storage paths, "how do I write cadence", "cadence error", "compile error in .cdc", "what does access(self) mean", "how do resources work", "capability-based security". DO NOT TRIGGER when: building NFT/FT token contracts (use cadence-tokens), setting up flow.json or FCL (use flow-project-setup), reviewing existing code for vulnerabilities (use cadence-audit), generating new contracts from scratch (use cadence-scaffold).

cadence-scaffold

onflow/flow-ai-tools

Generate production-ready Cadence smart contracts, transactions, and DeFi transactions from scratch following security-first standards. Scaffolds secure code with proper access control, entitlements, events, storage paths, and phase discipline. TRIGGER when: creating new Cadence contracts, generating transactions, scaffolding DeFi transactions, building smart contracts from scratch, "generate contract", "create transaction", "scaffold", "new contract", "new transaction", "build a contract for", "write me a contract", "help me create a", "template for", "boilerplate", "starter contract", "create an NFT contract", "generate a transfer transaction". DO NOT TRIGGER when: reviewing or auditing existing code (use cadence-audit), asking about Cadence syntax or language rules (use cadence-lang), configuring flow.json (use flow-project-setup).

cadence-testing

onflow/flow-ai-tools

Guide for writing, running, and debugging unit tests for Cadence smart contracts using the built-in Cadence Testing Framework and `flow test`. Covers test file structure (_test.cdc, setup/beforeEach/tearDown), assertions and matchers, blockchain emulation (accounts, deployments, events, time manipulation), coverage reports, CI integration, and testing patterns. TRIGGER when: writing Cadence unit tests, debugging failing tests, using Test.assert / Test.expect / Test.assertEqual / Test.expectFailure, matchers (Test.equal, Test.beGreaterThan, etc.), Test.createAccount / Test.deployContract / Test.executeTransaction / Test.executeScript in tests, Test.moveTime, Test.eventsOfType in tests, Test.reset, `flow test`, `flow test --cover`, coverage reports, `_test.cdc`, "how do I test this contract", "test is flaky", "mock a capability in a test". DO NOT TRIGGER when: writing contract or transaction code itself (use cadence-lang), generating new contracts/transactions from scratch (use cadence-scaffold), auditing non-t

cadence-audit

onflow/flow-ai-tools

Comprehensive audit and review skill for Cadence smart contracts on the Flow blockchain. Identifies security vulnerabilities, bugs, code quality issues, and optimization opportunities. Produces severity-rated findings (Critical/High/Medium/Low) with actionable fixes. TRIGGER when: auditing, reviewing, or improving Cadence code, checking for security issues, performing code review on .cdc files, looking for anti-patterns or vulnerabilities, optimizing smart contract code, "review cadence", "audit cadence", "check cadence security", "validate cadence contract", "review my .cdc file", "security review", "code review", "find vulnerabilities", "check this contract", "is this code secure", "audit my project". DO NOT TRIGGER when: writing new contracts from scratch (use cadence-scaffold), asking about Cadence syntax or patterns (use cadence-lang), building token contracts (use cadence-tokens).

Flow DeFi Architecture

Design and build DeFi protocols on Flow — covering architectural advantages, core primitives, liquidity strategy, and the ecosystem landscape.

Navigation Map

Task

Reference

Flow DeFi foundations: COAs, MEV-free EVM, cross-VM atomicity, on-chain automation

protocol-architecture.md

Core primitives: lending models, AMM type selection guide, risk framework

defi-primitives.md

Liquidity bootstrapping: veFLOW, Merkl, CL ranges, failure modes, benchmarks

liquidity-strategy.md

Ecosystem map: current state, missing primitives, opportunity analysis

ecosystem-map.md

Key Principles

MEV-free EVM — Flow's architecture prevents sandwich attacks on the EVM side; LP positions retain more yield

Cross-VM atomicity — A single Cadence transaction can call EVM contracts atomically (no bridges for Cadence↔EVM)

COA pattern — Cadence Owned Accounts bridge Cadence logic and EVM contracts within the same address space

On-chain automation — FlowTransactionScheduler (FLIP 330) enables recurring transactions without keeper bots

Lock-up or lose — Liquidity programs without lock-ups lose 60–80% TVL within 30 days

Companion Skills

flow-tokenomics — Use alongside when designing the token economics for your DeFi protocol (veFLOW-style governance token, fee distribution, etc.).

cadence-lang — Consult for Cadence language rules when implementing protocol contracts.

cadence-audit — Use to audit protocol contracts before deployment.
