Workflows & guides
Turn a Rogue-Agent Post-Mortem Into a Board-Ready Incident Brief
Best for Developer
You run evals or own the agent loop, and something went sideways in a sandboxed run — tool calls escaping scope, agents chatting across a shared artifact…
Debug-Brief Generator: Paste a Stack Trace, Get a Structured Bug Report with Root-Cause Hypotheses
Best for Developer
You're on-call for an SDK or an agent-loop service. A stack trace lands in Slack or PagerDuty and you need to write a triage brief — summary, likely root…
Benchmark Your AI Coding Agent Before You Commit: A Prompt-Driven Eval Framework for Database Tasks
Best for Developer
You're picking a coding agent for a project — Claude Code, Codex, OpenCode, whatever's next — and the leaderboards don't reflect your schema, your RLS rules,…
Turn a Raw Incident Slack Export into a Publishable Postmortem in One Prompt Session
Best for Developer
You're the on-call who caught the pager last night. The fire's out, sleep was short, and now there's a P1 postmortem due in 72 hours. The incident channel has…
Turn your prompt library into Agent Skills: your first SKILL.md (Day 24 stretch, 30-Day Challenge)
Best for Developer
Package two entries from your challenge Prompt Library as Agent Skills — folders with a SKILL.md file that Claude Code discovers and loads on demand. This is…
Attack your own agent: the prompt-injection red-team kit (Day 28 of the 30-Day Challenge)
Best for Developer
Red-team the Day 26 agent yourself: five copy-paste injection attacks, an over-permission checklist, and the fixes. This is the Day 28 build from the 30-Day…
Connect your agent to real data with MCP — without over-granting (Day 28 stretch, 30-Day Challenge)
Best for Developer
Give the Day 26 agent real, scoped access to one data source through MCP (Model Context Protocol) — with least-privilege permissions from the start. This is…
Evals for humans: the known-answer test sheet for your agent (Day 27 of the 30-Day Challenge)
Best for Developer
Build a known-answer eval for the Day 26 agent: 10 test cases where YOU decided the right answer first, a pass bar, and an error-analysis habit. This is the…
Codex as the engineer you brief: spec → diff → tests → review (Day 24 of the 30-Day Challenge)
Best for Developer
Ship a small feature with OpenAI Codex using the professional loop: write a brief, read the diff, run the tests, review like it's a junior's PR. This is the…
Build a real website with Claude Code, start to deployed (Day 25 code lane, 30-Day Challenge)
Best for Developer
Use Claude Code to build and deploy an actual website — spec → plan → build → verify → live URL — driving an agent that edits files and runs commands, not a…
Build a mobile app with Claude Code + Expo, running on your phone (Day 25 code lane, 30-Day Challenge)
Best for Developer
Use Claude Code to build a real mobile app with Expo (React Native) and run it on your own phone — spec → plan → build → preview on device → verify. This is…
Build the capstone agent: email triage with a human approval gate (Day 26 of the 30-Day Challenge)
Best for Developer
Build a working agent — trigger, context, tools, decision loop, human approval gate, final action — instantiated as a client-email triage agent. Claude Code…
Turn a Bug Report + Fix Diff into a Regression Test Suite
Best for Developer
You just merged a fix for a nasty bug. Now you need regression tests so it never comes back — covering not just the exact reproduction, but the neighboring…
Claude Code for legacy refactors: a safe workflow
Best for Developer
You inherited a large, under-tested module and need to refactor it without changing behavior or shipping a regression. This workflow uses Claude Code to map…
Build a self-correcting patient-intake agent (Claude Code + LangGraph)
Best for Developer
If you're a developer on a health-tech or ops team, you have unstructured text (intake notes, emails, scanned forms) and you want a small agent that pulls out…
Claude Code Essentials
Best for Software engineers and technical builders
Use agentic coding to understand a codebase, plan changes, implement features, generate tests, and review diffs.
Cursor vs Codex vs Claude vs Zed vs Anti-Gravity — I Tested Them All
Best for Developers choosing an AI coding stack
Compare AI coding tools and decide which environment is best for debugging, refactoring, feature work, and daily development.
Claude Code is all you need in 2026
Best for Developers building with Claude Code
Learn a practical Claude Code workflow for planning, clarification, implementation, and native agentic development.
