by getsentry · part of getsentry/xcodebuildmcp

Use when reviewing XcodeBuildMCP runtime boundary changes across MCP, direct CLI invocation, daemon-routed tools, and Xcode IDE bridge routing.

🧰 Not standalone. This skill ships with getsentry/xcodebuildmcp and only works together with that tool — install the tool first, then add this skill.

This is the playbook your agent receives when the skill activates — you don't need to read it to use the skill, but it's here to audit before installing.

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
