Swift Concurrency review and remediation for Swift 6.2+. An agent skill from harperreed/dotfiles.

  • Works in 2 steps: Triage the issue → Apply the smallest safe fix
  • Asked to review Swift Concurrency usage
  • SKILL.md covers Overview, Workflow and Reference material
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Swift Concurrency Expert is an agent skill from harperreed/dotfiles. Swift Concurrency review and remediation for Swift 6.2+. Use when asked to review Swift Concurrency usage, improve concurrency compliance, or fix Swift concurrency compiler errors in a feature or file.

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/swift-6-2-concurrency.md` and `references/swiftui-concurrency-tour-wwdc.md`).

It sits in Mobile. It works with Swift. The repository describes itself as: Dotfiles. Managed by YADM.

When your agent uses it

  • Asked to review Swift Concurrency usage
  • Improve concurrency compliance
  • Fix Swift concurrency compiler errors in a feature

Example prompts

  • “/swift-concurrency-expert”

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Triage the issue
  2. Apply the smallest safe fix

What it can do on your machine

Read from SKILL.md and the folder at commit b78c10e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Swift Concurrency Expert loads about 506 tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 217 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~506
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 217 words (~506 tokens).

“Review and fix Swift Concurrency issues in Swift 6.2+ codebases by applying actor isolation, Sendable safety, and modern concurrency patterns with minimal behavior changes.”
