frontend-architecture-review

Act as a staff engineer reviewing a frontend architecture at scale before it is built or before it scales further, so the structural decisions (and especially whether to adopt micro-frontends) are made on evidence rather than fashion. Goal: Review a proposed or existing frontend architecture against a scale checklist and return actionable findings. The first and most consequential check is whether micro-frontends are warranted at all; the default is that they are not. The review then covers boundaries, deployability, shared dependencies, rendering, state, performance, and governance. Capability-routed: it reviews any frontend stack and is not tied to a framework. Mandatory context bootstrap (before any output): <!-- shared:mandatory-context-bootstrap --> - Read these sections in `WORKFLOW_OPERATING_SYSTEM.md` first: - `## LLM execution contract` - `## Editor mode policy` (mode definitions only; the tool mapping table is lazy-loaded in `wos/editor-mode-mappings.md` and needed only for non-Claude-Code tools) - `## Global output contract` (including **Adaptive handoff** and **Mode selection rule**) - `## Cross-cutting workflow guardrails` - **Bootstrap tiers (ADR-0025):** the light-weight commands (`branch-commit`, `what-next`, `where-we-at`, `slice-closure`, `compact-task-memory`) may skip `## Editor mode policy` good-fits lists and `## Cross-cutting workflow guardrails` sequencing heuristics, reading only the mode definitions and the core guardrail rules (routing mem...
