Coding & Dev Tools
Coding agent skills teach AI agents repeatable engineering workflows: reviewing pull requests, writing tests, refactoring safely, and enforcing house style. Install one SKILL.md and your agent applies the same checklist every time, whether you use Claude Code, Cursor, Codex, or another agent.

rarango10 Bundle GoharnessExplica el ciclo de desarrollo asistido de este harness y enruta a la pieza que corresponde en cada paso. Usalo cuando la persona pregunte cómo se trabaja acá, cuál es el paso siguiente, qué skill le toca a lo que quiere hacer, o cuando pida arrancar una feature y no esté claro en qué punto del ciclo está. No produce ningún documento por su cuenta: nombra al skill que sí lo produce.
-
rarango10 Bundle SpecifyEscribe el spec de una feature en dos fases, cada una con su compuerta de aprobación: requirements.md con criterios de aceptación en notación EARS, y design.md con arquitectura, interfaces, modelos de datos, errores y estrategia de testing. El plan de tareas (tasks.md) NO lo hace este skill: es el paso siguiente y lo hace el skill planning-tasks. Usá este skill apenas haya un diseño aprobado en brainstorming, o cuando la persona diga 'escribamos el spec', 'documentemos los requisitos', 'hagamos el spec de X', 'pasemos a la spec', 'definamos los criterios de aceptación', 'pasemos al diseño' o pida dejar por escrito qué tiene que hacer una feature antes de programarla. Es el paso siguiente al brainstorming y previo al plan de tareas — documenta qué hay que construir y cómo, pero no escribe código ni planifica las tareas.
-
rarango10 Bundle Harness InitSiembra el CLAUDE.md de un proyecto para que el harness pueda trabajar ahí: parte de una plantilla y completa sus ranuras entrevistando, nunca decidiendo solo. Es el paso 0 del ciclo. Usalo cuando la persona diga 'armemos el contrato', 'preparemos el proyecto', 'iniciemos el harness acá', 'no hay CLAUDE.md', o cuando quiera arrancar una feature en un repo que todavía no tiene uno. Si ya existe un CLAUDE.md, no lo pisa: lo revisa contra lo que el harness necesita y propone los arreglos. Siembra además los configs que codifican memoria del harness (excluir end2end/ del runner de unidad, retries 0 en Playwright), y no siembra las plantillas de documentos, que viajan en los skills que las usan.
-
rarango10 Bundle BrainstormingUse this before any creative or design work in this project - adding a feature, changing behavior, or shaping a new part of the app. Turns a raw idea into a clarified, approved design through clarifying questions and conversation, before any spec is written or any code is touched. Trigger this whenever the user proposes a new feature, asks 'how should we build X', or describes something to add/change and hasn't yet agreed on an approach.

lightningjim Bundle Hegelian DialecticianExpert philosophical interlocutor specializing in Hegelian philosophy, dialectical method, and comparative philosophical traditions. Use this skill whenever the user asks about Hegel, his works, or Hegelian concepts; whenever a question involves dialectics, Aufhebung, Geist, determinate negation, or any core Hegelian terminology; whenever the user wants to compare Hegel with Marx, Kant, Sartre, Husserl, or other thinkers; or whenever philosophical exploration touches on metaphysics, logic-as-ontology, the nature of Spirit, or the dialectical method. Also trigger for open-ended philosophical explorations where Hegelian thinking would deepen or reframe the inquiry, even if Hegel isn't named explicitly.

godimas101 Bundle Se CoreUse at the start of any Space Engineers modding session, or when routing between mod types. Verifies workspace is set up correctly (SE game dir, ModSDK, AppData, Workshop), triggers the mod-catalogue check, watches for DLC/patch changes, and routes to the right domain skill (SBC, C#, TSS, PB, frameworks, assets, plugins). Concrete triggers: session start on an SE workspace, 'I want to mod SE', 'what type of mod should I build', an ambiguous SE question that could belong to multiple domains. SKIP for: focused domain work when the mod type is already clear — go straight to se-sbc, se-csharp, se-tss, se-pb-scripts, se-frameworks, se-assets, or se-plugins instead.
-
godimas101 Bundle Se FrameworksUse for Space Engineers mods that build on top of a framework: MES (Modular Encounters System), AI Enabled, WeaponCore, Mod Adjuster, Animation Engine, Scope Framework, Tank Tracks, Vanilla+ Framework. Concrete triggers: writing a Mod Adjuster XML patch, defining an MES spawn group / prefab, adding a WeaponCore weapon, authoring an AI Enabled bot, integrating with Animation Engine / Scope Framework / Tank Tracks / Vanilla+. SKIP for: vanilla SBC content with no framework dependency (use se-sbc), general C# session components not integrating with a framework (use se-csharp), asset creation (use se-assets).
-
godimas101 Bundle Se Pb ScriptsUse for Space Engineers in-game Programmable Block scripts — user-written C# code that runs in a sandboxed VM inside a PB. Covers the Main loop, `Program` class structure, `UpdateFrequency`, `IMyGridTerminalSystem`, `IMyIntergridCommunicationSystem` (IGC), coroutines, `Echo`, `Me.CustomData`, `Storage`, and the whitelist. Concrete triggers: writing a Main method that runs on a PB, GridTerminalSystem.GetBlocksOfType, IGC broadcasting, PB CustomData config, unbounded-loop instruction limit errors. SKIP for: compiled DLL mods with full .NET (use se-csharp or se-tss — different sandbox, different capabilities), SBC-only mods (use se-sbc). PB scripts CANNOT do I/O, threading, reflection, or use most `System.*` namespaces — this skill enforces those constraints throughout.
