Workflows for building, testing, and shipping code

CSS development workflows with Tailwind composition, semantic naming, and dark mode by default

Firebase project workflows including setup, features, debugging, and validation

Create high-converting, visually distinctive landing pages with Vibe Discovery process and anti-AI-slop principles

Xcode-free iOS development with xtool - build SwiftPM apps on Linux, Windows, and macOS without Xcode

Token-efficient code generation pipeline - parallel implementation with hosted LLM (Cerebras) for ~60% token savings. Includes MCP server.

Parallel exploration of implementation approaches - implements multiple variants simultaneously and lets tests determine the winner

Iterative artifact refinement with investigation-first judge board - constructs problem-specific judges that read the code, understand the problem, and propose evidence-based improvements

End-to-end testing with real dependencies - no mocks allowed; scenarios with real data are the only source of truth

Mandatory final sanity check before commits/PRs - catches security vulnerabilities, logic errors, and bugs that slip through tests

Verify documentation claims against codebase reality - two-pass extraction with pattern expansion for comprehensive drift detection

Slack workspace integration MCP server - create channels, invite users, post messages, manage threads for team collaboration

Prepare codebases for public/open-source release and audit them for openness - full lifecycle prep or standalone review

PR health assistant - monitors CI, triages review comments, fixes issues with systematic prevention. Uses gh CLI and gh-pr-review extension.

Digital drugs that modify AI behavior through prompt injection

System administration and operational tooling

Automatically updates terminal title with emoji + project + topic context for quick visual cues when switching terminals

Structured procedures for Linux system diagnostics and maintenance via SSH/tmux with Ubuntu/Debian cleanup checklists

Agentic binary reverse engineering for ELF binaries on ARM64, ARMv7, x86_64 - hypothesis-driven analysis with radare2, Ghidra, GDB, QEMU

Multi-agent architecture and agent capabilities

Architecture patterns for multi-agent systems with orchestrators, sub-agents, and tool coordination

Decision-making through deliberation - seeking unity through discernment rather than consensus through debate

Dispatch panels of specialized subagents to review projects — expert audits, first-impression personas, task-completion flows, and pedantic nitpicks

Parallel exploration powered by diverse perspectives - independent agent panels propose, build variants in worktrees, review, pick a winner, and synthesize the best of all variants into the final result

A server that provides social media functionality for AI agents, enabling them to interact in team-based discussions.

Tiered-delegation execution where Sonnet plans a spec into sprints, a cheap Haiku agent builds and self-verifies against the gate, and a scoped Sonnet fix runs only on failure - benchmarked ~64% cheaper than Opus at equal quality.

Reflection frameworks and personal operating systems

Personal operating system for executives - reflection frameworks, goal systems, coaching-style reviews (Gustin, Ferriss, Robbins, Lieberman, Campbell, Eisenmann, Collins, Martell, Gerber, Blank)

Systematic worldview articulation - surface beliefs, identify tensions, generate narrative outputs for personal philosophy documentation

Batch-process meeting transcripts from Obsidian vault into structured summaries with knowledge graph updates, people notes, and concept extraction

A lightweight MCP server that provides Claude with a private journaling capability to process feelings and thoughts
