What problem does it solve? Operating private infrastructure from a public skill repository risks leaking hostnames, credentials, topology, and secrets into public outputs, while unguarded writes can cause production outages. This Skill enforces a strict public/private boundary: all environment-specific facts live in a private operations repo resolved through a local context pointer, and every operation is classified into safety tiers before execution. ## Core Features & Use Cases - Tiered safety workflow: Classifies work as read-only inventory, reversible pilot writes, or production-impacting mutations, requiring approval, identity checks, and rollback plans before any apply. - Redacted NPMplus operations engine: Ships a generic Python CLI for NPMplus proxy-host inventory, pilot status, and lifecycle enable/disable with per-ref authorization, identity fingerprint verification, and write-evidence gates. - Private context discovery: Resolves the private operations repo from $CODE_HOME, $CODEX_HOME, or ~/.code local-context.toml files without ever printing private paths or values. - Use Case: An operator needs to disable a canary proxy host in NPMplus. The Skill validates the private context schema, confirms the authenticated principal and target domain fingerprint, checks snapshot/rollback readiness booleans, runs a dry-run, and only then applies the mutation with redacted output. ## Quick Start Ask the agent to check whether private infra context is configured and show the redacted NPMplus pilot status before planning any change.
