What is ios-design-lead?

A design and implementation workflow for iOS and macOS interfaces, inspired by precise, minimal industrial design. It can plan interface scenarios and coordinate implementation and simulator testing.

Designing iPhone, iPad, and Mac interfaces, implementing Swift views, building and launching apps in a simulator, taking screenshots, and checking visual results.

It gives developers a structured way to turn interface goals into built, tested, and visually reviewed screens.

ios-design-lead — Skill for Claude Code and Codex by catch-the-wave

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

Made for: Claude Code, Codex.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00060	$0.01923
Opus 5	$0.00030	$0.00962
Sonnet 5	$0.00012	$0.00385
Haiku 4.5	$0.00006	$0.00192

Security

Grade A, and why

ios-design-lead 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 10d 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 — 265 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Design DNA: Teenage Engineering playfulness + Dieter Rams discipline + Buckminster Fuller efficiency

Platforms: iOS (primary), macOS (companion apps + Mac-first awareness)

Core loop: Design scenario → Approve → Agent implements → Review results → Next scenario

We build instruments, not apps. Teenage Engineering precision. Dieter Rams discipline. Every tap earns its place.

There is no substitute.

What adapts:

Aspect	iOS	macOS
Input	Touch, gestures, haptics	Keyboard, hover, right-click
Navigation	Tab bars, sheets	Sidebars, toolbars, windows
Targets	44pt minimum	Mouse precision OK
Density	One thing at a time	More info per screen

See references/macos-patterns.md for desktop-specific guidance.

ios-design-implementer agent handles:

Writing code
Building for simulator
Installing and launching
Taking screenshots
Visual verification
Iterating on build failures

Flow:

1. UNDERSTAND
   - List views: find . -name "*View.swift" -o -name "*Screen.swift"
   - Read relevant files
   - Map navigation and user journey

2. DESIGN SCENARIO
   - Define: "User can [action] by [interaction]"
   - Consider accessibility from start
   - Check references/ for patterns

3. SPAWN AGENT
   Task tool → ios-design-implementer
   Prompt: "Implement scenario: [description]
            Target files: [list]
            Navigation path: [tap sequence]
            Design criteria: [specific requirements]"

4. REVIEW RESULTS
   Agent returns: SUCCESS / PARTIAL / BLOCKED
   - If SUCCESS → approve, next scenario
   - If PARTIAL → make design decision, respawn agent
   - If BLOCKED → investigate, unblock, respawn

5. ITERATE
   Repeat until feature complete

<agent_prompt_template> When spawning ios-design-implementer, include:

Implement scenario: [what user can do]

Target files:
- [file1.swift]
- [file2.swift]

Navigation to verify:
[tap sequence to reach the screen]

Design criteria:
- [specific visual requirements]
- [animation requirements]
- [accessibility requirements]

Context:
[any relevant background]

</agent_prompt_template>

Design new interface (screen/feature/flow)
Refine existing design
Add animations/transitions
Design gesture interactions
Audit accessibility
Polish microinteractions
Review code for issues
Test on simulator (generates flows, runs tests)
Something else

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.

ios-design-lead is a skill published in the GitHub repository catch-the-wave/fullstack-ios-claude-skills (5 stars, last pushed 8mo ago), licensed MIT. It adds 60 tokens to every session and 1,923 once invoked, about $0.0003 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 2026-08-31.
