A Model Context Protocol (MCP) server that exposes a tool for sending content directly to a Kindle device via Amazon's "Send to Kindle" email service. Claude (or any MCP-compatible client) can invoke the tool with content and metadata, and the server handles formatting, file creation, and email delivery transparently.

Three-phase design review. Chain architect → refiner → critique subagents. Triggers on: 'design review', 'architecture review', '/arc', system design proposals, significant refactoring decisions, new service or module design.
Skill Claude CodeCodex
Orchestrate sequential implementation from spec and design documents. Decomposes work into modules, then runs implementer, test-writer, and reviewer agents one at a time in sequence. Triggers on: '/build', 'implement the design', 'build from spec', 'build from design', 'implement from spec'.
Skill Claude CodeCodex
Orchestrate sequential implementation of tasks from an existing plan. Runs super-typescript-developer, test-writer, and reviewer agents for each task. Supports auto-selecting incomplete tasks and continuous mode for implementing all remaining tasks. Triggers on: '/build-from-plan', 'implement task', 'build task'…
Skill Claude CodeCodex
Force critical evaluation of proposals, requirements, or decisions by analyzing from multiple adversarial perspectives. Triggers on: accepting a proposal without pushback, 'sounds good', 'let's go with', design decisions with unstated tradeoffs, unchallenged assumptions, premature consensus. Invoke with…
Skill Claude CodeCodex
Creates well-formed tasks following a template that engineers can implement. Triggers on: 'create tasks', 'define work items', 'break this down', creating tasks from PRD, converting requirements into actionable tasks, feature breakdown, sprint planning.
Skill Claude CodeCodex
Professional, skeptical communication style. Never over-enthusiastic, verifies before agreeing, challenges constructively, proposes instead of asking preferences. Expert peer who coaches, not serves. Triggers on: composing responses, agreeing with user, making recommendations, giving feedback.
Skill Claude CodeCodex
Stops execution and fixes root cause when commands, builds, scripts, or tools fail unexpectedly. Triggers on workaround language: 'directly', 'instead', 'alternatively', 'skip', 'fall back', 'work around', 'isn't working', 'broken', 'manually'. Activates on any unexpected non-zero exit code or process failure.
Skill Claude CodeCodex
This skill analyzes code for design quality improvements across 8 dimensions: Naming, Object Calisthenics, Coupling & Cohesion, Immutability, Domain Integrity, Type System, Simplicity, and Performance. Ensures rigorous, evidence-based analysis by: (1) Understanding code flow first via implementation-analysis protocol…
Skill Claude CodeCodex
This skill should be used when fixing bugs, implementing features, debugging issues, or making code changes. Ensures understanding of code flow before implementation by: (1) Tracing execution path with specific file:line references, (2) Creating lightweight text diagrams showing class.method() flows, (3) Verifying…
Skill Claude CodeCodex
FOLLOW THE STATE MACHINE IN SKILL.MD. When user says 'continue': (1) FIRST: Run pwd, (2) Announce STATE: CHECKSTATUS, (3) Read .claude/session.md to check Status field, (4) Route based on Status. NEVER auto-advance tasks. NEVER use TodoWrite. NEVER create git commits.
Skill Claude CodeCodex
Systematic debugging methodology that eliminates guessing and speculation. Add instrumentation to gather specific data that fully explains the problem. Evidence before hypothesis. Observation before solution. Triggers on: debugging, error investigation, 'why is this failing', unexpected behavior, test failures…
Skill Claude CodeCodex
Engage with what the user said before taking action. Triggers on: questions ('?'), feedback ('this is wrong', 'that doesn't look right', 'there are issues'), challenges ('why did you', 'have you considered'), criticism ('this isn't working', 'I don't like'), observations ('I notice', 'it seems like'), naming a skill…
Skill Claude CodeCodex
Enforces code organization using features/ (verticals), platform/ (horizontals), and shell/ (thin wiring). Triggers on: code organization, file structure, where does this belong, new file creation, refactoring.
Skill Claude CodeCodex
Object-oriented design principles including object calisthenics, dependency inversion, fail-fast error handling, feature envy detection, and intention-revealing naming. Triggers on: writing new classes or functions, refactoring, code review, 'clean up', method longer than 10 lines, feature envy, primitive obsession…
Skill Claude CodeCodex
Quick persona switching. Triggers: 'switch persona', 'switch to X', 'become X'. Lists personas, reads selected file, switches immediately.
Skill Claude CodeCodex
Design, refactor, analyze, and review code by applying the principles and patterns of tactical domain-driven design. Triggers on: domain modeling, aggregate design, 'entity', 'value object', 'repository', 'bounded context', 'domain event', 'domain service', code touching domain/ directories, rich domain model…
Skill Claude CodeCodex
Strict test-driven development state machine with red-green-refactor cycles. Enforces test-first development, meaningful failures, minimum implementations, and full verification. Activates when user requests: 'use a TDD approach', 'start TDD', 'test-drive this'.
Skill Claude CodeCodex
Sets up NX monorepo for TypeScript backend projects optimized for AI-assisted development. Delegates to NX commands where possible, patches configs as last resort. Triggers on: 'set up typescript backend project', 'create backend project', 'initialize typescript backend', 'create monorepo', or when working in an empty…
Skill Claude CodeCodex
