Skills listed under Developer Productivity.
Systematic Debugging
Find the root cause before you fix anything: a four-phase process of evidence, patterns, one hypothesis at a time and a tested fix, with a stop rule after three failed attempts.
Handoff
Compacts the current conversation into a handoff document so a fresh agent session can pick the work up.
TDD
Test-first development one thin slice at a time: write a failing test, make it pass, and test only at seams you agreed on.
Prototype
Builds a throwaway prototype to answer one design question: a clickable HTML model for logic, or several UI variations to compare.
Grill with Docs
Interview you about a plan or design and write down the decisions as ADRs and a glossary along the way.
Grill Me
Start a relentless interview that sharpens a plan or design, one question at a time.
Chrome DevTools Agent
Control and inspect a live Chrome browser through the Chrome DevTools MCP: navigate, click, fill forms, take snapshots and screenshots, read the console and network, and profile performance.
MCP Builder
A guide for building high-quality MCP servers in TypeScript or Python: research, design, implementation, testing and evaluations.
Receiving Code Review
Handle review feedback with technical rigour: understand it, check it against the code, push back when it is wrong, clarify before acting and implement one item at a time.
Web Application Testing
Create Playwright automation for inspecting, testing, and debugging local web applications.
Security Threat Model
Threat model a code repository: trust boundaries, assets, attacker capabilities, concrete abuse paths and mitigations tied to real files, written up as one concise Markdown report.
Writing for Agents
A reference for writing documents agents read, such as skills, CLAUDE.md and AGENTS.md, so they behave predictably.
Excalidraw Diagram Generator
Turn a plain-language description into an Excalidraw diagram file: flowcharts, mind maps, architecture, sequence, ER, class and swimlane diagrams, with templates and helper scripts.
Verify and Stop
Checks whether work meets its acceptance criteria and stops there, without adding scope.
Test-Driven Development (TDD)
Write the failing test first, watch it fail, write the minimum code to pass, then refactor: the red-green-refactor loop with strict rules and a checklist.
Domain Modeling
Builds your project's shared vocabulary: challenges fuzzy terms, tests them with edge cases, and records them in GLOSSARY.md and ADRs.
Brainstorming (idea to approved design)
Turn an idea into an approved design before any code is written: classify the task, ask one question at a time, compare approaches and get your sign-off at each stage.
Product Requirements Document (PRD)
Write a PRD that links business goals to technical execution: problem, users, measurable requirements, non-goals, specs, risks and a phased roadmap.
Incident Post-Mortem (blameless)
Guide a team through a structured, blameless post-mortem: timeline, root cause with the 5 Whys, impact numbers and action items with owners and due dates.
Spec-Driven Development
Write a structured spec before any code: surface assumptions, cover objective, commands, structure, style, testing and boundaries, reframe vague asks as testable success criteria, and stop for human approval before planning.
Changelog Generator
Turns your git commits into a customer-friendly changelog, grouped by features, improvements, security and fixes.
Draw.io Diagram Generator
Create, edit and validate draw.io diagram files with correct mxGraph XML: flowcharts, architecture, sequence, ER and UML class diagrams, with templates and helper scripts.
Markdown and Mermaid Writing
Write Markdown documents with Mermaid diagrams for workflows, schemas, timelines and architecture: syntax guides for 21 diagram types, document templates, accessibility metadata and render checks.
Grilling
Has your agent interview you in numbered rounds, with a recommended answer for each question, until every decision in your plan is settled.
