Fold the operational half of ArgoCD work into this skill, which until now covered only authoring the Copier-templated repo. The two never overlapped: authoring edits files in git, connecting applies objects to a cluster. - Add references/connecting-a-repo.md: host-key trust, repository Secret registration with its project-scoping decision table, bootstrap apply ordering, SSO RBAC, prerequisites, and verification commands. - Add references/connect-env-vars.md: layered .env loading, variable table, CLI flags, and SSH deploy-key rules. - Add SKILL.md section 11 plus scope-routing rows, and state the split: sections 1-10 author, section 11 operates. - Map the numbered cluster/0000-bootstrap layout onto the cluster/argocd layout, since the connect scripts reference those folder names directly.

development-gitops-argo-cd
Agent Skill for GitOps repositories where ArgoCD syncs cluster state from a
Copier-templated Git repo — app-of-apps Application manifests under cluster/argocd/,
Helm values.yaml.jinja templates under cluster/resources/, Jinja2 conditional directory
names used as feature flags, and per-environment copier-answers.yaml files.
The rules are repo-agnostic; references/cogarchhubgitops-reference.md records
CogArchHubGitOps as the concrete reference implementation (bands in use, flag names, global
settings, ordering dependencies).

The three-layer contract
Every managed resource spans three layers that share one feature flag and one conditional directory expression:
copier.yaml → declares the flag + variables
cluster/argocd/{{ 'NNN-name' if flag }}/ → ArgoCD Application
cluster/resources/{{ 'NNN-name' if flag }}/ → Helm values
