What it does
Write Swift is an agent skill from KartikLabhshetwar/better-shot. How to write modern Swift well — modeling with value types, Swift 6 data-race safety and approachable concurrency (@concurrent, main-actor-by-default, actors, task groups), protocols and generics (some vs any), API design, performance and ARC, Swift Testing, macros, and the modern language features agents don't know about yet. Use when writing, reviewing, or migrating Swift, or when a concurrency error, a hang, a data race, a retain cycle, or a performance problem needs fixing.
Its SKILL.md is about 10k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering iOS development. It works with Swift and macOS. The repository describes itself as: Screenshot, screen recording, and video editor for macOS. Native SwiftUI app with capture deck, 75+ customizable shortcuts, URL scheme automation, and self-hosted cloud sharing…
When your agent uses it
- Migrating Swift
- A concurrency error
- A performance problem needs fixing
Example prompts
- “/write-swift”
Workflow steps
12 steps, taken from the step headings in SKILL.md.
- Model data with value types
- Errors and optionals — make the failure paths visible
- Concurrency: stay single-threaded until profiling says otherwise
- Sendable and sharing data
- Structured concurrency
- Concurrency in SwiftUI
- Protocols and generics
- API design — clarity at the point of use
- Performance — measure, then choose
- ARC and object lifetime
- Testing — Swift Testing by default
- Macros
What it can do on your machine
Read from SKILL.md and the folder at commit 102b364. 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
Shell commands in SKILL.md call:
swift
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
Write Swift loads about 10k tokens when it runs. Until then it costs about 124 tokens; SKILL.md has 5,283 words of instructions outside code blocks.
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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 5,283 words (~10,489 tokens).
“How to write Swift the way the language wants to be written, current through Swift 6.4.”

Write Swift is an agent skill from KartikLabhshetwar/better-shot. How to write modern Swift well — modeling with value types, Swift 6 data-race safety and approachable concurrency (@concurrent, main-actor-by-default, actors, task groups), protocols and generics (some vs any), API design, performance and ARC, Swift Testing, macros, and the modern language features agents don't know about yet.
When should I use Write Swift?
Write Swift fits situations like: migrating Swift; A concurrency error; A performance problem needs fixing.
How do I install Write Swift in Claude Code?
Run `npx skills add KartikLabhshetwar/better-shot --skill write-swift -a claude-code`. Or copy the skill folder (.agents/skills/write-swift in KartikLabhshetwar/better-shot) into .claude/skills/write-swift in your project. Claude Code loads it when a task matches its description.
How do I install Write Swift in Codex?
Run `npx skills add KartikLabhshetwar/better-shot --skill write-swift -a codex`. Or copy the skill folder (.agents/skills/write-swift in KartikLabhshetwar/better-shot) into .agents/skills/write-swift in your project. Codex loads it when a task matches its description.
Can I use Write Swift in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add KartikLabhshetwar/better-shot --skill write-swift -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/write-swift, .gemini/skills/write-swift, .github/skills/write-swift and .opencode/skills/write-swift in your project.
What does Write Swift need to run?
Going by SKILL.md and its folder, Write Swift needs the command-line tools its instructions call (swift).
Does Write Swift access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Write Swift safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Write Swift use?
Write Swift has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Write Swift use?
About 10k tokens (SKILL.md is roughly 42k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Write Swift?
Skills that share tags, products or a category with Write Swift: macOS Spm App Packaging (Dimillian/Skills, 4k stars), Snapshot Tests (microsoft/SwiftStreamingMarkdown, 378 stars), Build Run Debug (robinebers/openusage, 4.3k stars) and Bootstrap iOS (RayFernando1337/rayfernando-skills, 130 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
