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

1. 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

2. Validate environment and policy first:

   • Call validate_sandbox_policy with target project path and required SDKs.
   • If validation fails, stop and return remediation.
   • If diagnostics are needed, inspect details.diagnostics (probe_mode, effective_required_sdks, detected_sdks_raw, detected_sdks_normalized).

Optional preflight:

• Before build, you MAY call inspect_xcode_sdks (read-only) to compare SDK detection context with validate_sandbox_policy.

3. Run build:

   • Call build_visionos_app with confirmed inputs.
   • On success, capture job_id, artifact_path, artifact_sha256, and duration_ms.
   • On build_failed, call inspect_build_diagnostics with the returned job_id before considering shell-level investigation.

4. Fetch artifacts:

   • Call fetch_build_output with the job_id from step 2.
   • Return artifact metadata and optional logs.

Error Handling Matrix

Error code	Where it appears	Action
path_not_allowed	validate/build	Ask user to add project parent path to visionos.allowed_paths, restart server, rerun from step 1
scheme_not_allowed	build	Ask user to add scheme to visionos.allowed_schemes, restart server, rerun from step 2
sdk_missing	validate	First inspect details.diagnostics; if needed call inspect_xcode_sdks; then ask user to install/fix visionOS SDK settings and rerun from step 1
devtools_security_disabled	validate	Ask user to run DevToolsSecurity -enable, then rerun from step 1
xcode_unlicensed	validate	Ask user to accept license (sudo xcodebuild -license), then rerun from step 1
disk_insufficient	validate	Ask user to free disk space and rerun from step 1
timeout	build	Suggest increasing max_build_minutes or reducing build load; rerun from step 2
build_failed	build	Call inspect_build_diagnostics with job_id; only consider direct shell investigation if MCP diagnostics are unavailable or insufficient
artifact_expired	fetch	Ask user to rerun build to create fresh artifacts, then rerun fetch
job_not_found	fetch	Verify job ID and rerun build if needed

Output Format

Use this concise response template:

• skill: seiro-mcp-visionos-build-operator
• mode: seiro-mcp-preferred
• steps:
  • inspect_xcode_schemes: skipped or succeeded or failed(<code>)
  • validate_sandbox_policy: ok or error(<code>)
  • build_visionos_app: succeeded or failed(<code>)
  • inspect_build_diagnostics: skipped or succeeded or failed(<code>)
  • fetch_build_output: skipped or succeeded or failed(<code>)
• job_id: <uuid or n/a>

• next_action: <single concrete next step>

Guardrails

• Do not change MCP contracts or tool IDs.
• Do not skip validate_sandbox_policy in the standard flow.
• Prefer Seiro MCP over direct xcodebuild / swiftc for Xcode and visionOS project workflows.
• Do not bypass Seiro MCP with direct shell build or typecheck commands unless the user explicitly asks for shell-level execution or MCP diagnostics/build tools cannot handle the task.
• Keep MCP-only usage fully supported and unchanged.
