by getsentry · part of getsentry/xcodebuildmcp

Use when reviewing XcodeBuildMCP rendering, streaming fragment, next-step, and CLI output mode changes for boundary violations.

🧰 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 Rendering and Streaming Review

Review guardrails for rendering boundaries, streaming fragments, and output modes.

Review scope

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

Files to inspect

  • src/rendering/**
  • src/types/domain-fragments.ts
  • src/types/runtime-status.ts
  • src/runtime/tool-invoker.ts
  • src/runtime/__tests__/tool-invoker.test.ts
  • xcodebuildmcp.com/app/docs/_content/architecture-rendering-output.mdx
  • xcodebuildmcp.com/app/docs/_content/architecture-tool-lifecycle.mdx
  • xcodebuildmcp.com/app/docs/_content/output-formats.mdx

Guardrails

  • Tool handlers do not branch on CLI vs MCP output mode.
  • Fragments represent progress, not final contract data.
  • Final structured output remains canonical.
  • Do not invent json/jsonl render strategies.
  • Streaming tools emit typed fragments and one final structured result.
  • Non-streaming tools do not emit unnecessary fragments.
  • Keep ctx.emit and xcodebuild pipeline emitFragment contexts separate.
  • Keep next-step rendering in runtime/rendering boundary.

Validation

  • npm test -- src/runtime/__tests__/tool-invoker.test.ts
  • npm run test:snapshots
  • npm run typecheck
  • npx skill-check .agents/skills/xcodebuildmcp-rendering-streaming-review
