Ed's repo of Claude Code plugins, centered around a research-plan-implement workflow. Only a tiny bit cursed. If you're lucky.
Skill Claude CodeCodex
Use when analyzing a large corpus of text, code, or data that exceeds a single agent's effective context - orchestrates parallel Worker subagents, Critic review subagents, and a final Summarizer subagent with task tracking and failure recovery.
Skill Claude CodeCodex
Use to decide what kind of generic agent you should use.
Skill Claude CodeCodex
Use when creating a new Claude Code plugin or setting up plugin structure - provides complete file organization, manifest format, and component definitions for commands, agents, skills, hooks, and MCP servers.
Skill Claude CodeCodex
Use when creating specialized subagents for Claude Code plugins or the Task tool - covers description writing for auto-delegation, tool selection, prompt structure, and testing agents.
Skill Claude CodeCodex
Use when creating, releasing, or maintaining a Claude Code Plugin Marketplace - covers marketplace.json schema, version management, release checklists, changelog conventions, and validation to prevent sync drift between plugin.json and marketplace.json.
Skill Claude CodeCodex
Use when completing development phases or branches to identify and update CLAUDE.md or AGENTS.md files that may have become stale - analyzes what changed, determines affected contracts and documentation, and coordinates updates.
Skill Claude CodeCodex
Use when writing skills, CLAUDE.md files, agent prompts, or any directives that involve shell commands, environment variables, API credentials, file creation, or git operations - prevents secrets leakage into LLM context, unsafe shell patterns, and credential exposure.
Skill Claude CodeCodex
Use when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes.
Skill Claude CodeCodex
Use when writing instructions that guide Claude behavior - skills, CLAUDE.md files, agent prompts, system prompts. Covers token efficiency, compliance techniques, and discovery optimization.
Skill Claude CodeCodex
Use when creating or updating CLAUDE.md files for projects or subdirectories - covers top-level vs domain-level organization, capturing architectural intent and contracts, and mandatory freshness dates.
Skill Claude CodeCodex
Use when creating new skills, editing existing skills, or verifying skills work before deployment - applies TDD to process documentation by testing with subagents before writing, iterating until bulletproof against rationalization.
Skill Claude CodeCodex
ALWAYS use this skill when writing or refactoring code. Includes context-dependent sub-skills to empower different coding styles across languages and runtimes.
Skill Claude CodeCodex
Use when invalid data causes failures deep in execution - validates at every layer data passes through to make bugs structurally impossible rather than temporarily fixed.
Skill Claude CodeCodex
Use when writing, reviewing, or modifying Rust code - covers error handling with thiserror+miette, type system patterns, async and serde conventions, testing crates, dependency pinning, and module organization.
Skill Claude CodeCodex
Use when writing TypeScript code, reviewing TS implementations, or making decisions about type declarations, function styles, or naming conventions - comprehensive house style covering type vs interface rules, function declarations, FCIS integration, immutability patterns, and type safety enforcement.
Skill Claude CodeCodex
Use when writing database access code, creating schemas, or managing transactions with PostgreSQL - enforces transaction safety with TX naming, read-write separation, type safety for UUIDs/JSONB, and snakecase conventions to prevent data corruption and type errors.
Skill Claude CodeCodex
Use when writing or refactoring code, before creating files - enforces separation of pure business logic (Functional Core) from side effects (Imperative Shell) using FCIS pattern with mandatory file classification.
Skill Claude CodeCodex
Use when writing or modifying React components, planning React features, or working with .jsx/.tsx files - provides modern React patterns with TypeScript, hooks usage, component composition, and common pitfalls to avoid.
Skill Claude CodeCodex
Use when writing tests for serialization, validation, normalization, or pure functions - provides property catalog, pattern detection, and library reference for property-based testing.
Skill Claude CodeCodex
Use when writing documentation, guides, API references, or technical content for developers - enforces clarity, conciseness, and authenticity while avoiding AI writing patterns that signal inauthenticity.
Skill Claude CodeCodex
Use when writing or reviewing tests - covers test philosophy, condition-based waiting, mocking strategy, and test isolation.
Skill Claude CodeCodex
Use after initial design context is gathered, before brainstorming - resolves contradictions in requirements, disambiguates terminology, clarifies scope boundaries, and verifies assumptions to prevent building the wrong solution.
Skill Claude CodeCodex
Use when creating or developing anything, before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning, alternative exploration, and incremental validation.
Skill Claude CodeCodex
Use when executing implementation plans with independent tasks in the current session - dispatches fresh subagent for each task, reviews once per phase, loads phases just-in-time to minimize context usage.
