structure-swift-sources

structure-swift-sources is a skill for Claude Code, Codex from gaelic-ghost/socket. It costs 69 tokens per session (1,447 once invoked), scanned A, original, Apache-2.0.

A guide to reorganizing Swift source files by feature, layer, and declaration group. It also standardizes section markers, file headers, and separate TODO or FIXME lists.

In plain words
What is it for?
Use it to split oversized files, move declarations, extract view modifiers, organize sections, add plain-language headers, or move TODO and FIXME items into tracking files.
Why use it?
It makes large or untidy Swift codebases easier to navigate and keeps unfinished-work notes from being scattered through production code.

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

structure-swift-sources 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Structure Swift Sources

Purpose

Use this skill as the top-level workflow for structural cleanup inside existing Swift components. It governs file splitting, file moves, section grouping, plain-language file headers, and TODO or FIXME ledger extraction. scripts/run-workflow.fsx classifies the cleanup, loads policy, and hands off only DocC content or Xcode-owned membership operations. It is not the formatter or linter integration authority, and it is not the DocC authoring authority.

When To Use

  • Use this skill when the user wants to split oversized Swift files or move files into a clearer repo layout.
  • Use this skill when the user wants high-signal // MARK: sections, declaration grouping, or view-modifier extraction in SwiftUI code.
  • Use this skill when the user wants consistent block-comment file headers that describe a file's purpose and area of concern in plain terms.
  • Use this skill when the user wants structured project-and-file banner headers with deterministic project, filename, copyright, and optional cross-reference fields.
  • Use this skill when the user wants TODO or FIXME text moved out of source files into repo ledger files.
  • Use this skill when a Swift package or Xcode app repo has drifted away from the intended feature-plus-layer directory shape.
  • Recommend format-swift-sources first when formatter or linter setup is missing, unclear, or stale.
  • Recommend author-swift-docc-docs when the task becomes symbol documentation, DocC article work, landing-page structure, topic groups, or DocC-oriented review.
  • Recommend swift-package-build-run-workflow or swift-package-testing-workflow when structural cleanup turns into ordinary package execution or SwiftPM validation.
  • Recommend xcode-build-run-workflow when structural cleanup turns into active Xcode execution, scheme validation, file-membership follow-through, or guarded project mutation work.
  • Recommend xcode-testing-workflow when structural cleanup turns into active Xcode test validation or test-target diagnosis.
  • Recommend bootstrap-xcode-workspace --operation align for product guidance alignment. A deliberately standalone package uses its own explicit repository-maintenance contract.

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.
