What is seiro-mcp-visionos-build-operator?

A guided workflow for building and diagnosing visionOS projects, Apple's software for spatial-computing devices, through Seiro MCP. It covers scheme inspection, sandbox-policy checks, builds, diagnostics, and build-output retrieval.

Use it to discover Xcode schemes, validate sandbox settings, build a visionOS app, inspect failures, and retrieve output after a successful build.

It gives build failures a defined diagnostic path and keeps build operations in the available MCP workflow.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00086	$0.01408
Opus 5	$0.00043	$0.00704

Security

Grade B, and why

seiro-mcp-visionos-build-operator scanned grade B with 1 finding 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 12d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

Display label: Seiro MCP VisionOS Build Operator

Listing summary: Build and diagnose visionOS projects with Seiro MCP

Purpose

This skill standardizes the operational flow for visionOS builds on Seiro MCP. It does not replace MCP tools. It orchestrates them in a predictable order. Its identifier follows the bundled skill prefix policy: seiro-mcp-.

When to Use / When Not to Use

Use this skill when:

The task involves an Xcode project or a visionOS project and requires build, scheme discovery, failure diagnosis, or artifact retrieval.
Seiro MCP tools are available and can cover the requested operation.
The user explicitly asks to use seiro-mcp-visionos-build-operator.

Do not use this skill when:

The task is unrelated to visionOS build operations.
The user explicitly asks to run raw shell commands such as xcodebuild or swiftc.
Seiro MCP is unavailable or cannot satisfy the requested operation.

Required Inputs

Collect and confirm these inputs before running the flow:

project_path (absolute path, allowed by server policy)
scheme
Optional workspace
Optional destination (defaults to Apple Vision Pro simulator destination)
Optional configuration
Optional extra_args
Optional include_logs for artifact fetch

Canonical Flow

Optional project/scheme discovery:
- If project_path or scheme is missing/unknown, call inspect_xcode_schemes first to discover candidate schemes.
- Treat .xcodeproj and .xcworkspace as directory packages, not regular files.
- Do not conclude that the project is missing based only on file-only searches such as rg --files or *.xcodeproj file globs.
- If local inspection is needed before the MCP call, use directory-aware discovery (for example, find . -maxdepth 1 -type d \$ -name "*.xcodeproj" -o -name "*.xcworkspace" \$).
- If project_path is omitted for inspect_xcode_schemes, resolution order is:
  1. .xcodeproj discovered in current working directory
  2. visionos.default_project_path from config.toml

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.
