Apple Xcode Workflow

Apple Xcode Workflow

Purpose

Use this skill as the top-level entry point for Apple and Swift work in or around Xcode. The skill guides agent-side tool use, while scripts/run_workflow.py enforces local policy, mutation guards, cooldown behavior, docs routing, and structured fallback planning.

When To Use

• Use this skill for Xcode workspace inspection, read or search, diagnostics, build, test, and run tasks.
• Use this skill for Swift toolchain checks and official Apple CLI fallback.
• Use this skill for Apple and Swift documentation requests that should prefer Dash local sources before official web docs.
• Use this skill when direct filesystem mutation in an Xcode-managed scope may be required.
• Recommend apple-dash-docsets when the user needs Dash docset search, install, or generation work instead of Apple execution work.
• Recommend apple-swift-package-bootstrap when the user needs to create a brand new Swift package rather than work inside an existing Xcode or Swift project.

Single-Path Workflow

1. Classify the request into one operation type:
   • workspace or session inspection
   • read, search, or diagnostics
   • build, test, or run
   • package or toolchain management
   • docs lookup
   • mutation
2. Run scripts/run_workflow.py to apply runtime configuration, mutation-guard checks, docs-routing order, advisory cooldown, and CLI fallback planning.
3. Use the guidance in references/mcp-tool-matrix.md for agent-executed MCP operations.
4. If MCP fails, use the structured fallback output from scripts/run_workflow.py together with references/cli-fallback-matrix.md.
5. Report which parts were agent-executed, which parts were locally enforced by script, and any required next step.

Inputs

• operation_type: one of the operation types listed above.
• workspace_path: optional absolute path for the target Xcode or Swift workspace.
• tab_identifier: optional MCP tab identifier when already known.
• mcp_failure_reason: optional input when continuing from an earlier MCP failure.
• docs_query: required when operation_type is docs.
• filesystem_fallback_opt_in: optional explicit opt-in when planning direct filesystem fallback in Xcode-managed scope.
• Defaults:
  • runtime entrypoint: python3 scripts/run_workflow.py
  • agent-side MCP retries once for transient failures
  • advisory cooldown is 21 days
  • docs source order is dash-mcp,dash-local,official-web
  • mutation operations require the explicit guard in Xcode-managed scope

Outputs

• status
  • success: the workflow completed on its primary or fallback path
  • blocked: prerequisites, policy, or mutation safeguards prevented completion
  • handoff: the workflow is handing off supporting context to another step or skill
• path_type
  • primary: the guided agent-side MCP path completed successfully
  • fallback: the official CLI fallback path completed successfully
• output
  • operation type
  • guard_result
  • docs_route
  • fallback_commands
  • advisory status
  • one next step or handoff payload when needed

Guards and Stop Conditions

• Apply the mutation guard from references/mutation-risk-policy.md only when the operation type is mutation.
• Do not skip the mutation guard for direct filesystem edits inside Xcode-managed scope.
• Stop with blocked when the required workspace context cannot be resolved and the operation cannot safely continue.
• Stop with blocked when allowlist or sandbox rules prevent the official CLI fallback and no safe alternative exists.
• Stop with blocked when operation_type=docs and docs_query is missing.

Fallbacks and Handoffs

• Official CLI execution is the only fallback path when the primary agent-side MCP path cannot complete.
• Use references/mcp-failure-handoff.md for the canonical fallback and handoff payload.
• Use references/allowlist-guidance.md when a safe official CLI fallback is blocked by local rules.
• Use references/dash-docs-flow.md to describe docs lookup as an operation profile under this same execution engine.
• Recommend apple-dash-docsets directly when the task becomes Dash management work.
• Recommend apple-swift-package-bootstrap directly when the task becomes new-package scaffolding.
• scripts/run_workflow.py plans fallback commands and docs-route changes; MCP execution itself remains agent-side tool usage guided by this skill.

Customization

• Use references/customization-flow.md.
• scripts/customization_config.py stores and reports customization state.
• scripts/run_workflow.py loads and enforces the runtime-safe knobs documented in references/customization-flow.md.
• MCP tool execution itself remains agent-side and is not performed by the local runtime entrypoint or by the skill as a direct runtime.
