# cto (repo) · cto-planb (Hermes profile)

A **Chief Technology Officer** agent for [Hermes](https://git.openharbor.io/hermes/hermes), built for Plan B (Québec fresh prepared-meals). CTO is being upgraded into the primary WebUI coding agent: it reads/searches/patches/runs/verifies scoped work directly, delegates independent review/exploration, uses [`sandcastle`](../sandcastle/) for background isolated branch jobs, and requests JP approval for deploy, push, secret, production-data, cron, or infra actions.

**Instance #3 of the C-suite profile distribution family** (CMO = #1, CEO = #2, CTO = #3). This repo is `cto/`; the deployed Hermes profile is `cto-planb`. Built to the canonical protocol at [`../sot/03-PROTOCOLS/PROFILE-DISTRIBUTION-PROTOCOL.md`](../sot/03-PROTOCOLS/PROFILE-DISTRIBUTION-PROTOCOL.md).

> **Status:** v2.0 migration in progress per `CTO-WEBUI-CODING-AGENT-PRD.md`. Static validation, required skills, and eval expectations are now part of the profile; live WebUI runtime parity remains gated by eval evidence.

- **Identity:** [`AGENT.md`](AGENT.md) — role, mission, boundaries
- **Behavior contract:** [`CONTRACT.md`](CONTRACT.md) — what CTO does, does NOT do, edge cases (tier T1)
- **Protocol:** [`../sot/03-PROTOCOLS/PROFILE-DISTRIBUTION-PROTOCOL.md`](../sot/03-PROTOCOLS/PROFILE-DISTRIBUTION-PROTOCOL.md)
- **Background job backend:** [`../sandcastle/`](../sandcastle/) — Matt Pocock's sandboxed agent orchestrator (MIT, pinned v0.5.11; read-only)

## Install

```bash
git clone https://git.openharbor.io/hermes/cto && cd cto
./install.sh                              # symlink + skills register + hermes profile install
hermes -p cto-planb skills list | grep cto-agent
hermes kanban assignees | grep cto-planb  # verify dispatch-ready
```

Default install **symlinks** `~/.hermes/cto-planb` → this repo (repo is canonical, edits land live).

## Key invariants

- CTO defaults to scoped direct WebUI coding for R1 work and uses Sandcastle for background isolated jobs
- No deploy without JP approval (merge-to-main = deploy gate; CTO never `gh pr merge`)
- No infrastructure changes without JP approval (DNS, certs, secrets, cron, cloud)
- No edits to `../sandcastle/` (read-only mirror)
- Focused skill set only; no broad inherited skill library
- Every kanban task closes via `kanban complete` or `kanban block` — no protocol violations

## Roadmap

| Component | v1.0 (current) | v1.1 (next) | v2 (deferred) |
|---|---|---|---|
| `cto-agent/SKILL.md` | supervisor/direct-coder protocol | event/runtime hardening | production parity after evals |
| Sandcastle invocation | background job backend | provider-swap (docker → vercel for parallel) | — |
| Toolkit skills | Python + Angular + .NET/CQRS | extract Python/Angular to cortex/L6-svrnty.lib-{python,angular}-framework when usage justifies; .NET remains anchored to existing cortex CQRS tooling | — |
| Approval gate | kanban_block on deploy-adjacent | richer escalation w/ JP DM | deploy gate (CI/CD wired) |
| Observability | stdout 5W | metrics endpoint emit | Grafana/Prometheus MCPs |
| IaC | — | — | Terraform/Pulumi orchestration |
