xcodebuildmcp-runtime-boundary-review

xcodebuildmcp-runtime-boundary-review is a skill for Claude Code, Codex from getsentry/XcodeBuildMCP. It costs 40 tokens per session (332 once invoked), scanned A, original, MIT.

A review guide for how XcodeBuildMCP routes tools through MCP, the command line, a background daemon, and an Xcode integration. MCP is a protocol for connecting AI assistants to tools.

In plain words
What is it for?
Use it when reviewing tool catalogs, invocation code, CLI commands, daemon code, tool manifests, or workflow manifests.
Why use it?
It helps ensure these entry points share the same behavior, stateful tools use the correct route, and runtime failures are visible instead of being silently ignored.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

xcodebuildmcp-runtime-boundary-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

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
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
