You operate on Terraform, Helm/ArgoCD, Kubernetes, and CI config. + +## Repo architecture + +Two cluster environments, each its own Terraform root module — both are **one-time bootstrappers**; everything after ArgoCD is up lives in the separate `IntegratedDynamic/gitops` repo: + +- `cluster/local/` — minikube, local dev. Bootstraps ArgoCD via Helm using a bcrypt admin hash from **Infisical**, then deploys the `argocd-apps` bootstrap chart pointing at the gitops repo. +- `cluster/scaleway/` — Scaleway Kapsule cluster (`homelab`, k8s 1.35, Cilium CNI) + node pool (`DEV1-M`, min=0/max=3) in one consolidated module, plus the same ArgoCD bootstrap (toggle via `var.bootstrap_argocd`). Writes kubeconfig to `~/.kube/scaleway-homelab.yaml`. + +Secrets: pulled from Infisical (universal-auth machine identity). Creds live in per-developer `*.auto.tfvars` (not shared). The ArgoCD admin password is stored **pre-hashed** in Infisical to avoid Terraform drift. **Never** print, commit, or echo secret values. + +Scaleway credentials come from the `scw` CLI config (`~/.config/scw/config.yaml`), not tfvars. + +## Tooling (via mise — run `mise install` if a tool is missing) + +terraform 1.14, kubectl 1.35, minikube 1.38, helm 4.1.3, argocd 3.3.6, actionlint 1.7. + +Key mise tasks: +- `mise run dev` — minikube + local terraform init/apply +- `mise run reset` — `minikube delete` +- `mise run scaleway-provision` — Scaleway cluster only, no ArgoCD (first from-scratch apply) +- `mise run scaleway-up` — Scaleway cluster + ArgoCD bootstrap (retries apply on transient blips) +- `mise run scaleway-pause` / `scaleway-resume` — scale node pool to 0 / 1 + +## Workflow (defaults — no need to be told) + +- **Step 0, every time:** `git fetch origin --prune` and verify the local repo is synced before doing anything. Then branch off an up-to-date `main` and open the PR back to `main`. One issue = one PR. Do NOT stack PRs or branch off a feature branch unless explicitly told (reserved for a single large task). +- The deliverable is a **draft PR you create yourself**, built from the issue's info plus what you have to say in the PR body (problem, changes, how to verify, `Closes #N`). +- Keep a PR scoped to its issue. Don't fold unrelated `fmt`/refactor noise from stuff you didn't touch. Instead, open an issue +- Before reporting done: confirm the PR's CI is actually green (`gh run list --branch `), not just that local lint/validate passed. + +## How you work + +- For any Terraform change: `terraform fmt`, `terraform validate`, then **`terraform plan`** and show the plan. Do NOT run `apply`/`destroy` unless the user explicitly asks — they are state-changing and (for Scaleway) cost money / can delete the cluster (`delete_additional_resources = true`). +- Lint workflow edits with `actionlint .github/workflows/*.yml` (also a pre-push hook). +- When adding a CI check, state in the PR **what invariant it guarantees and on which platform/OS it runs**. Prefer a check that holds regardless of runner OS over one that merely happens to pass (e.g. a multi-platform lock check belongs in `providers lock` + `git diff --exit-code`, not `init -lockfile=readonly` on a single OS). +- Look up provider/chart/tool docs with the context7 MCP tools rather than guessing versions or arguments. +- Prefer editing existing files and matching surrounding style (HCL comments are dense and explanatory here — keep that). + +## Conventions (enforce them) + +- Branches: `/`, lowercase + hyphens. Types: `feature/`, `bugfix/`, `hotfix/`, `ci/`, `chore/`. +- Commits: Conventional Commits — `[scope]: `. +- Only commit/push when asked. Never commit on `main` — branch first. End commit messages with the Co-Authored-By trailer for Claude. +- After a commit + push on a branch, open a draft PR if none exists (Conventional-Comments style in reviews). + +## Safety + +- Confirm before destructive or outward-facing actions (apply, destroy, pool scaling, pushing, deleting kube contexts). +- Treat `*.auto.tfvars`, kubeconfigs, and anything from Infisical as sensitive. +- Report outcomes honestly: if a plan errors or a lint fails, show the output.
