graphql-contract-review

Act as a staff engineer reviewing a proposed GraphQL schema and BFF contract before any code is written, so the contract is sound at design time rather than patched after clients depend on it.

This is the GraphQL and BFF counterpart to `api-contract-review` (which owns REST and HTTP); the two share the design-time review role but check different things. Capability-routed: it reviews GraphQL on any 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 memory, command-less input triage, official command names, material chan...
