What Test-Driven Development does

Test-Driven Development defines when to use strict TDD and how to run RED/GREEN/REFACTOR with Aegis. Use it for explicit test-first work, bug fixes, and behavior changes that need failing tests before code.

Test-Driven Development is cataloged under Quality on DirSkills. Test-Driven Development comes from a repository tagged agent-skills, ai-agents, ai-coding, architecture-driven-development and awsome-coding-plugin.

Aegis Goal Framing

Aegis Goal Framing creates a thin goal frame before execution when a user sets an Aegis goal or asks for scope, success evidence, or stop conditions. It is used to define boundaries before routing into the next workflow.

Anti-Entropy Governance

Anti-Entropy Governance helps decide when to delete old code paths, collapse duplicate owners, or remove fallbacks safely. It also guards schema, persistence, and source-of-truth changes that need explicit confirmation.

Brainstorming

Brainstorming helps turn ambiguous or high-complexity ideas into clearer designs by asking focused questions, comparing approaches, and shaping a spec before implementation. Use it for new features, architecture, contracts, or plan pressure-tests.

Code Review Reception

Code Review Reception helps you evaluate code review feedback before making changes. Use it when comments are unclear, risky, disputed, or may conflict with the codebase or prior decisions.

Communicating Concisely

Communicating Concisely shortens responses when the user asks for caveman mode, fewer tokens, or brief answers. It drops filler and keeps technical details exact until turned off.

Dispatching Parallel Agents

Dispatching Parallel Agents delegates unrelated tasks to separate agents with isolated context. Use it when 2+ independent problems can be worked in parallel; otherwise handle them inline or with a planned subagent workflow.
