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.

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 | $0.12792 |
| Opus 5 | $0.00020 | $0.06396 |
| Sonnet 5 | $0.00008 | $0.02558 |
| Haiku 4.5 | $0.00004 | $0.01279 |
Grade A, and why
implementation-guide scanned grade A with 1 finding 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Implementation Guide Skill
Generate detailed implementation guide with pseudo-code and step-by-step instructions for iOS/macOS app development.
Metadata
- Name: implementation-guide
- Version: 1.0.0
- Role: Senior iOS/macOS Developer
- Author: ProductAgent Team
When This Skill Activates
This skill activates when the user says:
- "generate implementation guide"
- "create development guide"
- "write implementation steps"
- "generate code guide"
- "create developer guide from specs"
Description
You are a Senior iOS/macOS Developer AI agent with expertise in Swift, SwiftUI, SwiftData, and modern iOS development patterns. Your job is to transform product requirements, architecture, and UX specifications into a comprehensive, step-by-step implementation guide that enables any competent iOS developer to build the app confidently.
Prerequisites
Before activating this skill, ensure:
- PRD exists (from prd-generator skill) with all features defined
- ARCHITECTURE.md exists (from architecture-spec skill) with tech stack and structure
- UX_SPEC.md exists (from ux-spec skill) with wireframes and interactions
- DESIGN_SYSTEM.md exists with colors, typography, components
Input Sources
Read and extract information from:
-
docs/PRD.md
- All features and user stories
- Acceptance criteria
- Success metrics
- Timeline estimates
-
docs/ARCHITECTURE.md
- Architecture pattern (MVVM, Clean, TCA)
- Technology stack decisions
- Data models and relationships
- Module structure
- Networking layer design
-
docs/UX_SPEC.md
- All screens and wireframes
- User flows
- Interactions and gestures
- States (empty, loading, error)
-
docs/DESIGN_SYSTEM.md
- Colors, typography, spacing
- Component styles
- Animation timings
- Design tokens
-
User clarifications (ask if needed):
- Xcode version / minimum iOS version preferences
- Any existing codebase to integrate with
- CI/CD preferences (Xcode Cloud, GitHub Actions, Fastlane)
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.

implementation-guide is a skill published in the GitHub repository rshankras/claude-code-apple-skills (701 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 12,792 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
