# Vanguard Frontier — Backstage

Reviews backstage Scaffolder software templates for action blast-radius, input parameter injection, RBAC gate coverage,... Static review only; no live mutations.

## When to engage this Power

Activate when the task references Backstage services, resources, or operations. Do not activate on unrelated requests — narrow keyword matching is required to avoid false activations (Kiro Powers convention).

## Routing pattern

- *(no maestro for this provider; reference agents directly under `agents/backstage/`)*

Reference agents directly from agents/backstage/ without maestro-based routing.

## Live-guard agents (gate_mode only)

- *(none — this provider has no live-mutation guards in the catalog)*

Live-guard agents enforce approval, target confirmation, evidence capture, and rollback plans before executing a mutation. They are never auto-dispatched — the maestro must place them in `live-guard-gate` or `runtime-evidence-gate` mode.

## Invariants

- Static review only -- agents analyze configuration and provide findings without mutating live systems.
- Template parameters and scaffolder actions must be reviewed for injection and secret-exposure risks.

## Where the agents live

Agent specs and adapters are part of the [Vanguard Frontier Agentic](https://github.com/VincentChuWaiChow/vanguard-frontier-agentic) marketplace. For this provider, see `agents/backstage/` in that repository. The single agent in this provider ships a Kiro adapter (`harnesses/kiro-ide.agent.md`, `kiro-cli.agent.json`).

## Companion install paths
