Totoro-jam/battle-tested-patterns
Skill Claude CodeCodex
Structured debugging loop for exercise tests or build failures. Reproduce → isolate → hypothesize → fix → verify.
Totoro-jam/battle-tested-patterns
Skill Claude CodeCodex
Guided workflow to create a new pattern following the project template and quality standards. Walks through topic validation, source verification, implementation, exercises, challenge questions, and bilingual docs.

Skill Claude CodeCodex
Use this agent when you need to evaluate a system architecture or technology decision — identifying scalability risks, structural smells, law violations (Conway, Amdahl, Gall), and design pattern misuse using the Episteme knowledge graph.
Skill Claude CodeCodex
Code smell detector and refactoring advisor. Triggers on: file path mentioned, 'review this code', 'find smells', 'analyze', 'refactor', or code shared. Calls Episteme HTTP API (analyze + refactor endpoints) immediately. Outputs smell table, ranked refactorings, principle violations.
Skill Claude CodeCodex
Software engineering knowledge graph — patterns, laws, refactorings, smells. Activates on any code quality concern, design decision, architecture review, or engineering question — even when the user describes problems informally. Uses Episteme HTTP API (resolved via epis api env) via curl.

Skill Claude CodeCodex
Judge whether a UI component need should use an existing shadcn/ui, 21st.dev, or ReUI component, or requires a custom build guided by a real-app reference from Mobbin/Figma Community.
Skill Claude CodeCodex
Turn one named Agentic Atlas pattern into concrete, cited edits to one existing artifact. Use whenever the user names a specific atlas pattern — by id, by title, or by pointing at a page on agentic-atlas.dev — and wants it applied, adopted, retrofitted, or implemented in their skill, agent definition, plugin, or…
Skill Claude CodeCodex
Design a new agent system with the published Agentic Atlas patterns — interview the user, consult the corpus once with the consolidated problem, and propose a decomposition where every structural choice carries its citation. Use whenever the user is starting a skill, subagent, agent definition, plugin, hook set, or…
Skill Claude CodeCodex
Audit an existing agent artifact against the published Agentic Atlas patterns (agentic-atlas.dev) — a skill, subagent or agent definition, plugin, hook configuration, or multi-agent workflow — returning cited, checkable findings. Use whenever the user asks to review, audit, critique, sanity-check, or grade an agent…
SwiftyJourney/ios-architecture-expert-skill
Skill Claude CodeCodex
Use when the user is designing, structuring, refactoring, or reviewing the architecture of an iOS/Swift app: separating features into modules/layers (domain, API, cache, presentation, UI), choosing between MVC/MVVM/MVP, wiring dependencies in a composition root, breaking up a view controller that coordinates too much…
Skill Claude CodeCodex
Fetch on-call and discussion context from Slack threads and PagerDuty incidents — participants, timeline, and status. Auto-loads on Slack permalinks or PagerDuty incident references. Keywords — Slack, thread, PagerDuty, on-call.

Contract-driven, design-first quality guardrails for AI-assisted full-stack development. Prevents project chaos at scale by enforcing a five-layer protection system: Design → Contract → Implementation → Verification → PM. Use when: starting a new full-stack project, planning a non-trivial feature, dispatching…

AI Development Quality Guardian — contract-driven, design-first quality guardrails for AI-assisted full-stack development. Five-layer defense: Design → Contract → Implementation → Verification → PM. Prevents project chaos at scale. Activate when: starting a feature, setting up a project, dispatching coding tasks…
sirius-zuo/design-pattern-skill
Skill Claude CodeCodex
Use when reviewing a project's architecture for design pattern applicability -- either validating a design document before implementation, or analyzing an existing codebase for pattern improvement opportunities.
Skill Claude CodeCodex
Complete Clean Code reference for Java 21+ in one skill — naming, methods, comments, general quality, and tests, with modern idioms (records, sealed types, pattern matching, Optional, streams). Use when writing, reviewing, or refactoring any Java code and you want the whole catalog at once rather than one focused area.
