Domain: prompt-engineering | Difficulty: intermediate | Source
Write tests as executable specifications. Descriptive test names directly improve generation quality (the AI treats them as natural language specs). Keep scopes tight — one behavior per prompt. Multiple small TDD cycles outperform single large generation requests. Enforce with pre-commit hooks as a hard quality gate.

Martin Fowler's 25-year Agile anniversary workshop concluded TDD "produces dramatically better results from AI coding agents" because it prevents agents from writing tests that validate their own broken implementations. The Tweag Agentic Coding Handbook now documents TDD-as-sp...
Domain: vibe-coding | Difficulty: advanced | Source Create three isolated subagents (test-writer, implementer, refactorer) with a UserPromptSubmit hook that forces RED→GREEN→REFACTOR cycles automatically. Context isolation between subagents prevents the LLM from "cheating" by...
Domain: agent-security | Difficulty: advanced | Source Five-layer defense post-Clinejection: (1) Scope --allowedTools to read-only for triage agents, (2) Separate cache boundaries between low/high privilege workflows, (3) Distinct npm tokens for nightly vs production, (4) OIDC...
Domain: agent-security | Difficulty: advanced | Source Audit all MCP servers with uvx mcp-scan@latest. Implement network egress allowlists (ARXON succeeded via unrestricted outbound access). Scope tool permissions with PreToolUse hooks. Isolate knowledge base per-session. Moni...
Domain: AI Productivity | Difficulty: Advanced Source: Security Boulevard Self-correcting quality loop: Claude generates, scans, reads rules, fixes until gates pass: 1. Install SonarScanner CLI and configure sonar-project.properties 2. Add SonarQube MCP server to Claude Code 3...
An ArXiv study analyzing Claude Code's design space found something that should make every "auto-generate your context files" workflow uncomfortable. Human-curated CLAUDE.md files improved task success rates by roughly 4 percentage points. LLM-generated CLAUDE.md files reduced...
