What it does
Build Feature is an agent skill from AstraFoundry/KumoApp. Build an iOS feature using ShipSwift component recipes. Use when the user says "build", "create", "add a feature", or describes an iOS feature they want to implement.
Its SKILL.md is about 630 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 iOS and SwiftUI. The repository describes itself as: A calm, native macOS client for the Mihomo proxy core, built with SwiftUI and a shared agent-friendly CLI. The licence is AGPL-3.0.
When your agent uses it
- The user says build
- Describes an iOS feature they want to implement
Example prompts
- “create”
- “add a feature”
- “/build-feature”
Requirements
- Node.js
- A credential in SHIPSWIFT_API_KEY
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Analyze the request: Break down the user's feature request into discrete components (UI, data, navigation, backend integration).
- Search for recipes: Use searchRecipes with relevant keywords to find matching ShipSwift recipes. Try multiple search terms if the first…
- Fetch full implementations: Use getRecipe for each relevant recipe to get the complete source code, architecture explanation, and…
- Present an integration plan: Before writing code, show the user
- Generate code: Adapt the recipe patterns to the user's project structure. Combine multiple recipes when the feature spans several areas…
- Provide integration checklist: List any required dependencies, Info.plist entries, or environment setup from the recipe documentation.
What it can do on your machine
Read from SKILL.md and the folder at commit 990ff36. 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:
npx
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
shipswift.app
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
SHIPSWIFT_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Build Feature loads about 632 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 295 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.

- description
- Build an iOS feature using ShipSwift component recipes. Use when the user says "build", "create", "add a feature", or describes an iOS feature they want to implement.
Build Feature with ShipSwift
Build production-ready iOS features by combining ShipSwift recipes -- copy-paste-ready SwiftUI implementations covering animations, charts, UI components, and full-stack modules.
Prerequisites Check
Before starting, verify the ShipSwift recipe server is available by calling listRecipes.
If the tools are not available, guide the user to visit shipswift.app for setup instructions, or run npx skills add signerlabs/shipswift-skills to install.
Workflow
Analyze the request: Break down the user's feature request into discrete components (UI, data, navigation, backend integration).
Search for recipes: Use
searchRecipeswith relevant keywords to find matching ShipSwift recipes. Try multiple search terms if the first query returns few results.Fetch full implementations: Use
getRecipefor each relevant recipe to get the complete source code, architecture explanation, and integration checklist.Present an integration plan: Before writing code, show the user:
- Which recipes will be used
- How they connect together
- What customizations are needed for their specific use case
Generate code: Adapt the recipe patterns to the user's project structure. Combine multiple recipes when the feature spans several areas (e.g., a chart view with shimmer loading animation).
Provide integration checklist: List any required dependencies, Info.plist entries, or environment setup from the recipe documentation.
Guidelines
- Always search recipes before writing code from scratch -- ShipSwift likely has a ready-made solution.
- Combine multiple recipes when the feature spans several areas.
- Use
SW-prefixed naming conventions for ShipSwift components (e.g.,SWShimmer,SWDonutChart). - View modifier methods use
.swlowercase prefix (e.g.,.swShimmer(),.swGlowScan()). - Keep Views lightweight; extract complex logic into ViewModels.
- Support Dark Mode and Dynamic Type by default.
- Prefer SwiftUI-native APIs over UIKit wrappers.
Pro Recipes
Some recipes require a Pro license ($89 one-time). If a recipe returns a purchase prompt, the user can buy at shipswift.app/pricing and set SHIPSWIFT_API_KEY in their environment.
