name: add
description: "Grow an already-bootstrapped infra repo by provisioning something NEW that does not exist yet: a new managed GitHub repo, a new resource on an existing provider (a Cloudflare DNS record, page rule, GitHub repo setting), or a brand-NEW provider (e.g. start managing GCP). Handles the config + Terraform + workspace wiring and ends on a green plan (the new thing shows as 'will be created'). Use this WHENEVER the user wants Terraform to create/manage a new thing in an existing infra repo. Trigger on: 'add a repo to Terraform management', 'manage another repo/domain/record', 'add a new CNAME/DNS record via Terraform', 'provision a new Cloudflare page rule', 'start managing GCP too', 'add a new provider', 'extend the infra repo'. Use AFTER infra-copilot:setup. Not for first-time bootstrap (infra-copilot:setup) or adopting resources that ALREADY exist at the provider (infra-copilot:import)."

# infra-copilot: add

Grow a repo that `infra-copilot:setup` already bootstrapped. Three flavors of "add," in
increasing blast radius. This file is a **router**: the reusable machinery — actor model,
handoff, resume, preflight — lives in [`../infra-copilot/references/protocol.md`](../infra-copilot/references/protocol.md); the
manifest in [`../infra-copilot/references/steps.yaml`](../infra-copilot/references/steps.yaml); per-provider detail under
[`../infra-copilot/references/`](../infra-copilot/references/).

> **New vs. existing.** `add` provisions things that **don't exist yet** — Terraform will
> `create` them, and a `create` in the plan is the *expected, correct* outcome. If the
> thing already exists at the provider and you're bringing it under management, that's
> **infra-copilot:import** (where a `create` means something went wrong).

## Precondition

`infra-copilot:setup` phases 0–4 are green. `add` extends a working repo; it does not
bootstrap credentials.

## Pick the flavor

### 1. Add a managed repo (smallest)

Terraform's `github-org` leaf manages repos. To add one:

1. **Config** — append the repo to `managed_repos` in `.infra-copilot/config.md`
   ([`../infra-copilot/references/config.md`](../infra-copilot/references/config.md)) and re-export `$REPO` if it's the first
   entry (the VCS repo HCP watches).
2. **GitHub App install scope** (`HUMAN` if the App is installed on selected repos) — the
   App must be able to see the new repo. If install is scoped, a human extends it in the
   org's App-install settings, then replies `done`. See
   [`../infra-copilot/references/github.md`](../infra-copilot/references/github.md).
3. **Terraform** — add the resource/module in `terraform/github/`, `terraform init` +
   `plan`. Green plan showing the new repo as **will be created** (or **imported**, if it
   already exists on GitHub — then hand to `infra-copilot:import`).

### 2. Add a resource to an existing provider

A new Cloudflare DNS record, page rule, or GitHub repo setting — the provider and its
workspace/token already exist, so this is pure Terraform:

1. Write the resource under the right leaf (`terraform/cloudflare/` or `terraform/github/`).
2. If it needs a permission the current scoped token lacks (e.g. a new Cloudflare resource
   type), the token needs widening — a `HUMAN` mint/paste. Scope-widening guidance:
   [`../infra-copilot/references/cloudflare.md`](../infra-copilot/references/cloudflare.md) and
   [`../infra-copilot/references/docs/secrets.md`](../infra-copilot/references/docs/secrets.md).
3. `plan` → green with the new resource as **will be created**. `apply` runs through HCP
   per your normal review flow.

### 3. Adopt a brand-new provider (largest — a design decision)

Adding a provider like **GCP** is a **locked-design-decision change**, not a routine add.
GCP is *not* provisioned today (template only). Before any Terraform:

1. **Decide, on the record** (`HUMAN`, step `gcp-decision` in
   [`../infra-copilot/references/steps.yaml`](../infra-copilot/references/steps.yaml)) — update
   `.infra-copilot/decisions.md` and `terraform/README.md`. Do not provision ahead of the decision.
2. **New leaf + workspace** — create `terraform/<provider>/`, a matching HCP workspace
   (same `create_ws` pattern as setup Phase 1, [`../infra-copilot/references/hcp.md`](../infra-copilot/references/hcp.md)),
   with the same safety toggles (auto-apply off, path-scoped triggers).
3. **Credential** — mint the provider's scoped token/service-account key (`HUMAN`) and
   paste it into the new workspace's variables (`HUMAN`, sensitive). The agent verifies via
   the vars API, never sees the plaintext.
4. **First plan** on the new leaf — same proof-of-credentials as setup Phase 4.

Template + rationale for the GCP case: [`../infra-copilot/references/gcp.md`](../infra-copilot/references/gcp.md).

## How to run

1. **Read config first** (shared protocol, Step 0) — [`../infra-copilot/references/config.md`](../infra-copilot/references/config.md).
2. **Pick the flavor** above; run its `AGENT` steps, stop + hand off on its `HUMAN` steps
   (App-scope change, token mint/paste, provider decision). Full actor/handoff/resume
   contract: [`../infra-copilot/references/protocol.md`](../infra-copilot/references/protocol.md).
3. **Verify with a plan.** Done = `terraform plan` green, the new thing shown as **will be
   created**, nothing unexpectedly destroyed. Then apply through your normal HCP review.
