app-config
Use when the user wants to manage application configuration files (properties, env, toml, ini, yaml, json, text) and deploy them as Kubernetes ConfigMaps — phrases like "I have a .env / .properties / application.yaml file, how do I use it with ConfigHub?", "generate a ConfigMap like kustomize configMapGenerator", "like kubectl create configmap but versioned", "inject env vars via envFrom", "ConfigMap with content hash for rolling restart", "mutable vs immutable ConfigMap", "validate my application config with a schema", "propagate config changes to the workload without kubectl edit". Authors an AppConfig Unit in the right toolchain, sets up the ConfigMapRenderer Target, links the rendered ConfigMap to the workload via Needs/Provides, and picks immutable (hashed name, history) or mutable (stable name + hash annotation) mode. Do not load for authoring a Kubernetes `ConfigMap` resource directly in a `Kubernetes/YAML` Unit (use `config-as-data` + `cub-mutate`), for Secrets (separate SecretStore story — see `references/yaml-patterns.md`), or for migrating Helm values files (use `import-from-helm` — charts already render their own ConfigMaps).
Quality
Discovery
SkippedBased on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
Implementation
SkippedReviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
