GreatCTO reads your go.mod and detects fiber + iot-embedded archetype from signals: imports, file structure, env vars, README hints.
Attaches the iot-embedded archetype overlay: OTA strategy, secure boot, ETSI EN 303 645 baseline, watchdog patterns. Override if your specifics differ; the defaults are sensible for Fiber-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 Fiber projects (connection-pool exhaustion, ORM N+1 queries, retry storms) β the agent's Step 0 includes the prior detection order. MTTR drops 94 % on second occurrence (methodology).

This is the shape of what senior-dev drafts for "OTA update endpoint" β auth first, schema validation, and the audit line the iot-embedded reviewer requires before gate:ship opens.

iot-embedded overlay.Device firmware with secure boot and OTA strategy.
Sensor fleets under ETSI EN 303 645.
RTOS apps (Zephyr / ESP-IDF / embassy) with watchdog patterns.
Fiber (Go) is not a typical fit for iot / embedded. The archetype overlay still attaches, but you may want to override defaults more aggressively. Check the iot-embedded 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 β 8 stages, 22 nodes, 2 human gates. Every node maps to a real agent on GitHub. Inspect the state machine β
$ npx great-cto init
Free, MIT, runs locally. Built as a Claude Code plugin β install with one command.
Eight stages, two human gates, four memory layers. Why this exact shape, and what I tried that didn't work.
One run, one feature, from prompt to merged PR. Time, cost, and gate-by-gate breakdown β no marketing math.
Regex vs LLM-based archetype detection, the false-positive count, and why I keep rejecting the obvious fix.
The bottleneck in agentic SDLC isn't model quality β it's process governance. Here's the state machine that closes the gap.
