🏛️ phoenix × gov-public

Ship government / public sector on Phoenix with sensible defaults.

Phoenix is a Elixir workable choice for government / public sector. GreatCTO auto-detects both — adds the gov-public archetype overlay, wires gov-public-specific gates, and runs 34 specialist agents around your existing Phoenix workflow.

What changes when GreatCTO joins your Phoenix project

Detection → overlay → gates → reviewers.

1 · DETECT

Stack + archetype

GreatCTO reads your mix.exs and detects phoenix + gov-public archetype from signals: imports, file structure, env vars, README hints.

2 · OVERLAY

Archetype pack

Attaches the gov-public archetype overlay: FedRAMP authorization scope, FISMA, 508 a11y, CJIS for law-enforcement. Override if your specifics differ; the defaults are sensible for Phoenix-style projects.

3 · GATES

Phoenix-aware reviewers

qa-engineer runs mix test --cover / credo --strict; security-officer audits Ecto query injection + Phoenix CSRF; performance-engineer profiles BEAM scheduler + Ecto pool.

4 · MEMORY

Cross-project lessons

Bugs you've hit before in other Phoenix 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).

Concrete walkthrough.

$ cd my-phoenix-app && npx great-cto init
✓ scanning manifests… found manifest
✓ stack: phoenix (Elixir)
✓ archetype: gov-public
⚠ archetype + stack combo is unusual — review overlay manually
✓ 34 agents ready

$ /start "add public records API"
▸ architect drafting ARCH-gov-public.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.

⚠ Honest caveat

Phoenix (Elixir) is not a typical fit for government / public sector. The archetype overlay still attaches, but you may want to override defaults more aggressively. Check the gov-public archetype page for the typical stack list and decide if your case is the right tool / right archetype.
