signerlabs/ShipSwift is a SwiftUI component library that also provides full-stack app recipes and an MCP server for AI coding tools. It helps developers and coding agents build iOS applications using reusable interface components and documented implementation patterns. The catalogue entries provide the skills, instructions, and MCP access needed to use ShipSwift with compatible agents.
Getting it into your agent
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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 28 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
- medium Data Exfiltration · line 41 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 5.1 | $0.00040 | $0.00505 |
| Opus 5 | $0.00020 | $0.00253 |
| Sonnet 5 | $0.00008 | $0.00101 |
| Haiku 4.5 | $0.00004 | $0.00051 |
Grade A, and why
build-feature 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 9d 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.
What it actually says
Build Feature with ShipSwift
Build production-ready iOS features by combining ShipSwift components — copy-paste-ready SwiftUI implementations covering animations, charts, UI components, and full-stack modules.
Workflow
-
Browse the catalog: Read
skills/catalog.mdto see all available components organized by category. -
Read the source: For each relevant component, read the Swift file directly from
ShipSwift/SWPackage/. For example:- Shimmer animation → read
ShipSwift/SWPackage/SWAnimation/SWShimmer.swift - Donut chart → read
ShipSwift/SWPackage/SWChart/SWDonutChart.swift - Auth module → read all files in
ShipSwift/SWPackage/SWModule/SWAuth/
- Shimmer animation → read
-
Present an integration plan: Before writing code, show the user:
- Which components will be used
- How they connect together
- What customizations are needed
-
Generate code: Adapt the component patterns to the user's project. Combine multiple components when the feature spans several areas (e.g., a chart view with shimmer loading).
-
Integration checklist: List required dependencies, Info.plist entries, or Xcode build phase settings (especially for
+iOS/+macOSplatform-filtered files).
Guidelines
- Always check the catalog before writing code from scratch — ShipSwift likely has a ready-made solution.
- Use
SW-prefixed naming (SWShimmer,SWDonutChart). - View modifiers use
.swlowercase prefix (.swShimmer(),.swGlowScan()). - Copy
SWUtil/alongside any component — it provides shared extensions. - For modules (
SWModule/), copy the entire module folder. - Support Dark Mode and Dynamic Type by default.
Pro Recipes (MCP)
Some full-stack recipes (backend + compliance + pitfall guides) are available via the MCP server at https://api.shipswift.app/mcp. If MCP tools (listRecipes, searchRecipes, getRecipe) are available, use them for extended content. The local source code works independently.
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.

build-feature is a skill published in the GitHub repository signerlabs/ShipSwift (2,984 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 505 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
