Product Ux Quality
Making software feel finished — UI states, forms, mobile, errors users can act on, accessibility, and the polish gap between "works" and "quality product". Use when building any user-facing screen or flow, reviewing UX, handling forms/validation, or when the user says "polish", "UX", "user experience", "looks unfinished", "empty state", "mobile", or "make it production quality".
Ai Agent Design
Designing and building AI agents — tool design, agent loops, context management, permissions/guardrails, memory, multi-agent orchestration, MCP, and agent evaluation. Use when building an agent that takes actions (calls tools/APIs, writes files, automates workflows), designing tool schemas, debugging agent misbehavior, or when the user says "AI agent", "agentic", "tool calling", "function calling…
Code Quality
Writing and reviewing maintainable, correct code in any language. Use when writing new modules, reviewing code, refactoring, naming things, handling errors, or when the user says "clean this up", "code quality", "review this", "refactor", "is this good code", or "best practices".
Deployment Safety
Safe shipping to production on any platform (Render, Vercel, AWS, Docker, bare VM). Use when deploying, releasing, configuring CI/CD, writing Dockerfiles or infra config, running migrations against production, or when the user says "deploy", "release", "go live", "ship", "rollback", or "production".
Requirements To Spec
Turning vague ideas, feature requests, and client asks into buildable, verifiable specs before any code is written. Use when starting a feature or product, when a request is ambiguous, when scoping an MVP, when writing user stories or acceptance criteria, or when the user says "build me", "I have an idea", "requirements", "spec", "scope", or "what should the MVP include".
Docs And Runbooks
Documentation that survives — READMEs that get someone running, ADRs that preserve decisions, runbooks that work at 2 a.m., and onboarding docs that scale the team. Use when writing or updating any project documentation, setting up a new repo, documenting operations or deploy procedures, capturing a decision, or when the user says "document this", "write a README", "runbook", "onboarding", "ADR",…
Ai Build Quality
Getting reliably high-quality software out of ANY AI model (Claude, GPT, Gemini, local models) — task packaging, context, verification, and drift control. Use when delegating coding work to an AI model, writing prompts/specs for AI-driven development, reviewing AI-generated code, setting up CLAUDE.md/AGENTS.md-style project instructions, or when the user says "have the AI build", "prompt for", "w…

Use when investigating a bug, a production incident, flaky behavior, "works on my machine", data corruption, or when the user says "debug", "why is this happening", "broken", "investigate", "root cause", or pastes an error/stack trace.
