# xcodebuildmcp-runtime-boundary-review — This skill examines the runtime boundary enforcement and guardrail mechanisms within XcodeBuildMCP, Sentry's Model Context Protocol server for iOS and macOS development. It focuses on validating how the tool isolates agent operations, manages resource access, and prevents unintended cross-boundary execution during build workflows. Use it to verify security posture and operational safety in agent-driven Xcode environments.

# XcodeBuildMCP Runtime Boundary Review

Review guardrails for runtime routing and invocation boundaries.

## Review scope

- Review-only by default.
- Do not edit product code unless the user explicitly requests implementation changes.

## Files to inspect

- `src/runtime/tool-catalog.ts`
- `src/runtime/tool-invoker.ts`
- `src/runtime/types.ts`
- `src/cli/**`
- `src/daemon/**`
- `manifests/tools/*.yaml`
- `manifests/workflows/*.yaml`
- `xcodebuildmcp.com/app/docs/_content/architecture-runtime-boundaries.mdx`
- `xcodebuildmcp.com/app/docs/_content/architecture-manifest-visibility.mdx`

## Guardrails

- MCP, CLI, and daemon paths use shared handlers.
- Stateful CLI tools route through daemon only when `routing.stateful` requires it.
- Do not treat daemon as a third manifest availability mode.
- Dynamic Xcode IDE tools keep daemon routing semantics.
- Catalog filtering respects availability, workflow selection, and predicates.
- Runtime failures surface via runtime/rendering status and fragments.
- Avoid silent fallbacks and parallel invocation paths.

## Validation

- `npm test -- src/runtime/__tests__/tool-invoker.test.ts`
- `npm run typecheck`
- `npx skill-check .agents/skills/xcodebuildmcp-runtime-boundary-review`
