murmur

Create and refine HEARTBEAT.md files for murmur — a CLI daemon that runs scheduled Claude prompts on a cron or interval schedule. Use this skill when the user wants to set up a recurring automated action (e.g., "monitor my GitHub issues", "check Hacker News for AI articles", "watch my endpoints", "send me a daily digest"). Guides the user through an interview, drafts the heartbeat prompt, tests it, and registers it with murmur's scheduler. Triggers: heartbeat, murmur, recurring task, scheduled action, cron, monitor, watch, automate, periodic check, scheduled prompt.

Expert code review of current git changes with a senior engineer lens. Detects SOLID violations, security risks, and proposes actionable improvements.

Autonomous triage agent that reviews untriaged GitHub issues, classifies them by type/priority/size, detects duplicates, and applies labels. Triggers: "triage issues", "review new issues", "label issues", "triage the backlog".

Expert in designing and building autonomous AI agents. Masters tool use, memory systems, planning strategies, and multi-agent orchestration. Use when: build agent, AI agent, autonomous agent, tool use, function calling.

Conduct enterprise-grade research with multi-source synthesis, citation tracking, and verification. Use when user needs comprehensive analysis requiring 10+ sources, verified claims, or comparison of approaches. Triggers include "deep research", "comprehensive analysis", "research report", "compare X vs Y", or "analyze trends". Do NOT use for simple lookups, debugging, or questions answerable with 1-2 searches.

Comprehensive guide to Effect-TS patterns for building robust TypeScript applications. Use when: (1) Writing Effect-TS code - effects, streams, layers, services, (2) Handling errors with typed errors and recovery, (3) Managing concurrency with fibers, queues, deferred, (4) Working with Schema for validation, (5) Building APIs or data pipelines, (6) Managing resources safely, (7) Understanding Effect fundamentals vs Promise/async-await. Triggers: "Effect", "effect-ts", "Effect.gen", "Effect.runPromise", "Schema", "Layer", "Service", "fiber", "Deferred", "Stream", "Chunk", "Option", "Either", "typed errors".

Designs system architecture, selects tech stacks, defines components and interfaces, addresses non-functional requirements. Trigger words - architecture, system design, tech stack, components, scalability, security, API design, data model, NFR, patterns, microservices, monolith

Create distinctive, production-grade terminal user interfaces with high design quality. Use this skill when the user asks to build CLI tools, TUI applications, or terminal-based interfaces. Generates creative, polished code that avoids generic terminal aesthetics.

Terminal User Interface (TUI) performance and UX guidelines for TypeScript applications using Ink and Clack. This skill should be used when building CLI tools, interactive terminal prompts, or developer tooling with TUI components. Triggers on tasks involving TUI components, CLI prompts, terminal rendering, keyboard input handling, or developer tooling.

UX research and design toolkit for Senior UX Designer/Researcher including data-driven persona generation, journey mapping, usability testing frameworks, and research synthesis. Use for user research, persona creation, journey mapping, and design validation.

Autonomous issue worker that picks the highest-priority, smallest-effort triaged GitHub issue, plans and implements changes in a git worktree, then runs final review. Use when told to "work on issues", "pick up an issue", "automate issue work", or "work on the next issue".
