argocd-advanced

Advanced ArgoCD operations beyond the core CLI/API — multi-cluster ApplicationSet generators, automated image updates, new-cluster bootstrapping, and workload onboarding via templated ApplicationSets. USE WHEN working with ApplicationSet CRDs (list, cluster, git, matrix, merge, SCM, pull request, plugin generators), configuring ArgoCD Image Updater (semver/digest/newest-build update strategies + git write-back), bootstrapping a new Kubernetes cluster into a multi-repo GitOps setup, registering clusters with proper labels for ApplicationSet targeting, onboarding a new workload via the standard ApplicationSet template, or troubleshooting any of these. For routine app sync/status/diff work use the core `argocd` skill instead.

ship

End-to-end branch delivery: commit (no AI attribution) → push → open a pull request → ensure a Board work item exists (create one per task, assigned to the configured user, if none) and link it → after merge, clean up branch and worktree. Auto-detects the platform from the remote — Azure Repos + Boards (azure-devops-node-api SDK; OAuth Bearer push fallback via `az`) or GitHub (Octokit; `gh` for auth). Scripts are TypeScript, run via `bun`. Use whenever asked to "ship", "ship it", "ship this branch", "open a PR", "push and open a PR", "raise a PR", "deliver this", "send this for review", or "create a PR and link the work item" — and when a direct push to main is blocked and the change needs to go through a PR instead. Also covers snapshotting the current state as an annotated git tag — use whenever asked to "save the current state", "tag this", "snapshot the state", "create a checkpoint", "tag a release point", or "mark where we are" (a git-tag checkpoint, distinct from PR labels/tags). Also opens a just-creat

mise

Set up, configure, and maintain development environments with `mise` (mise-en-place) — the polyglot tool/version manager, per-directory environment switcher, and task runner. ALWAYS use this skill when the user mentions mise, `mise.toml`, `.mise.toml`, `mise use`, `mise run`, pinning tool/language versions per project, an asdf / nvm / rbenv / pyenv / direnv replacement, a `.tool-versions` file, or wants project-scoped env vars and task automation in one config. Also trigger when scaffolding a dev environment for a repo, migrating from asdf/nvm/direnv/make to mise, adding a tool from a backend (npm, cargo, pipx, aqua, ubi/GitHub), or diagnosing "tool not found" / activation / shim problems. Covers house conventions, a sample-driven config template, workflows, a `mise.toml` best-practice linter, and a full CLI reference. NOT FOR system package management (apt/brew for OS libraries), Nix flakes, or make-style file-timestamp build graphs with complex dependency trees.

ArgoCD Advanced

Gotchas

ApplicationSet generators are ordered. With matrix/merge generators, the parent generator's result is the input to the child — get the order wrong and you get an empty parameter set with no error.

Image Updater + git write-back requires a write credential. A read-only repo cred will silently leave images stuck on the original version. Check Image Updater pod logs for permission denied on push.

Bootstrap cluster secrets must carry the labels your ApplicationSet generators select on. A cluster registered without the expected label key/value is invisible to existing ApplicationSets — and there is no error, just zero apps.

application-install ships a your organization/ExampleApp-specific template. The Workflows assume the multi-repo layout. If you're not in that environment, treat it as a reference pattern, not a runnable recipe.

CRD versions matter. ApplicationSet ships with ArgoCD 2.3+; certain generators (SCM, pull request) need 2.5+. Read References/applicationset.md Version Compatibility before adopting.
