Tdd Pattern

Category: Engineering  ·  Sub-category: testing  ·  Last updated:
Use this skill whenever you are running as the `red` or `green` agent on an agile-team-v2 task. Covers the discipline-based spec isolation between red and green (no private TASK*.md files exist; the only handoff is committed code/tests), the in-scope vs out-of-scope rules of the red/green pattern (applies to standard and architectural complexity features only — mechanical maintenance is a mono-agent task), the mono-assistant safeguard when one Claude instance must wear both hats sequentially (commit red first, fresh session before reading green-side material — `check.sh` audits this at sprint review), and the marker-based task lookup procedure (grep for `TODO(impl-<slug>, ac-<NNN>)` to locate the scaffolded body and its sibling test file). Loaded only by `red` and `green`. Other agents (architect, PM, sprint-planner, e2e-tester, reviewer, bug-detective) operate outside the live red/green isolation flow and do not need these rules.

From the source SKILL.md

The strict TDD workflow paired teammates run for standard and architectural complexity features in agile-team-v2. This skill captures the rules that only apply to red and green, so they can be removed from the global agile-project skill (which every agent loads).

What this skill does

Tdd Pattern is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/tdd-pattern/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Tdd Pattern Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
