Gin is a Go workable choice for web3 / defi. GreatCTO auto-detects both — adds the web3 archetype overlay, wires web3-specific gates, and runs 34 specialist agents around your existing Gin workflow.
GreatCTO reads your go.mod and detects gin + web3 archetype from signals: imports, file structure, env vars, README hints.
Attaches the web3 archetype overlay: oracle review, MEV protection, upgradeability (UUPS/Diamond/Beacon) decision, multisig. Override if your specifics differ; the defaults are sensible for Gin-style projects.
qa-engineer runs go vet / staticcheck / go test -race -cover; security-officer reviews context cancellation + goroutine leaks; performance-engineer profiles pprof CPU + heap.
Bugs you've hit before in other Gin projects (connection-pool exhaustion, ORM N+1 queries, retry storms) — the agent's Step 0 includes the prior detection order. MTTR drops 94 % on second occurrence (methodology).
$ cd my-gin-app && npx great-cto init ✓ scanning manifests… found manifest ✓ stack: gin (Go) ✓ archetype: web3 ⚠ archetype + stack combo is unusual — review overlay manually ✓ 34 agents ready $ /start "add multisig vault deposit handler" ▸ architect drafting ARCH-web3.md… ▸ pm decomposing into beads tasks… ⚐ gate:plan — your approval needed
Approve → 3 senior-devs run in parallel worktrees → 5 reviewers fan out in parallel → gate:ship → deploy. One real run walked stage-by-stage: /proof.
Gin (Go) is not a typical fit for web3 / defi. The archetype overlay still attaches, but you may want to override defaults more aggressively. Check the web3 archetype page for the typical stack list and decide if your case is the right tool / right archetype.
No black-box "AI does it all" loop. GreatCTO is a deterministic state machine — 8 stages, 22 nodes, 2 human gates. Every node maps to a real agent on GitHub. Inspect the state machine →
