What is apple-xcode-workflow?

A workflow guide for Apple and Swift development in Xcode, Apple's app-development environment. It covers inspecting projects, checking tools, diagnosing problems, building, testing, running, and finding Apple or Swift documentation.

Use it for Xcode workspace inspection, Swift toolchain checks, builds, tests, runs, diagnostics, and Apple or Swift documentation lookup.

It gives coding agents a consistent way to work with Xcode projects and choose appropriate checks or documentation sources. It also accounts for operations that may change files in an Xcode-managed project.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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	$0.00046	$0.01317
Opus 5	$0.00023	$0.00659
Sonnet 5	$0.00009	$0.00263
Haiku 4.5	$0.00005	$0.00132

Security

Grade A, and why

apple-xcode-workflow 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 2d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/advisory_cooldown.py, scripts/customization_config.py, scripts/detect_xcode_managed_scope.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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

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
Run scripts/run_workflow.py to apply runtime configuration, mutation-guard checks, docs-routing order, advisory cooldown, and CLI fallback planning.
Use the guidance in references/mcp-tool-matrix.md for agent-executed MCP operations.
If MCP fails, use the structured fallback output from scripts/run_workflow.py together with references/cli-fallback-matrix.md.
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

What ships with it

20 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
