Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/rohitg00/pro-workflow.git skills-src && mkdir -p .claude/skills && cp -r skills-src/skills/tdd .claude/skills/tdd && rm -rf skills-src

At a glance

Drive a change through a red-green-refactor loop - failing test first, minimal code to pass, then clean up.

  • Works in 4 steps: Red. Write one failing test that states… → Green. Write the least code that makes… → Refactor. Now clean up with the test as… → …
  • Implementing a feature
  • SKILL.md covers The loop, What makes a test worth writing, When to reach for it and Output contract
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

TDD is an agent skill from rohitg00/pro-workflow. Drive a change through a red-green-refactor loop - failing test first, minimal code to pass, then clean up. Use when implementing a feature or fixing a bug where correctness matters and a test can pin the behavior. Says "TDD", "test first", "red green refactor", "write the test first".

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Test-driven development. The repository describes itself as: Claude Code learns from your corrections: self-correcting memory that compounds over 50+ sessions. Context engineering, parallel worktrees, agent teams, and 17 battle-tested…

When your agent uses it

  • Implementing a feature
  • Fixing a bug where correctness matters and a test can pin the behavior

Example prompts

  • “test first”
  • “red green refactor”
  • “write the test first”
  • “/tdd”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Red. Write one failing test that states the next slice of behavior.
  2. Green. Write the least code that makes the test pass. Not the general
  3. Refactor. Now clean up with the test as a net: remove duplication,
  4. Repeat for the next slice. Small slices. The rate of feedback is the

What it can do on your machine

Read from SKILL.md and the folder at commit 86d5f27. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

TDD loads about 634 tokens when it runs. Until then it costs about 73 tokens; SKILL.md has 361 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~73
When it runs · the whole SKILL.md, loaded when a task matches
~634

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 361 words (~634 tokens).

“The agent codes better with a tight feedback loop than with a long specification. A failing test is the tightest loop there is: it states the target, and the target either goes green or it does not.”

Questions about TDD

What does TDD do?

Drive a change through a red-green-refactor loop - failing test first, minimal code to pass, then clean up. TDD is an agent skill from rohitg00/pro-workflow. Drive a change through a red-green-refactor loop - failing test first, minimal code to pass, then clean up.

When should I use TDD?

TDD fits situations like: implementing a feature; fixing a bug where correctness matters and a test can pin the behavior.

How do I install TDD in Claude Code?

Run `npx skills add rohitg00/pro-workflow --skill tdd -a claude-code`. Or copy the skill folder (skills/tdd in rohitg00/pro-workflow) into .claude/skills/tdd in your project. Claude Code loads it when a task matches its description.

How do I install TDD in Codex?

Run `npx skills add rohitg00/pro-workflow --skill tdd -a codex`. Or copy the skill folder (skills/tdd in rohitg00/pro-workflow) into .agents/skills/tdd in your project. Codex loads it when a task matches its description.

Can I use TDD in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add rohitg00/pro-workflow --skill tdd -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/tdd, .gemini/skills/tdd, .github/skills/tdd and .opencode/skills/tdd in your project.

What does TDD need to run?

SKILL.md names no scripts, command-line tools or credentials: TDD is instructions for the agent only.

Does TDD access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is TDD safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does TDD use?

No licence was found for TDD or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does TDD use?

About 634 tokens (SKILL.md is roughly 2.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to TDD?

Skills that share tags, products or a category with TDD: TDD (pietheinstrengholt/rssmonster, 564 stars), TDD Workflow (hellangleZ/burn-in-cceverywhere-ralph, 112 stars), TDD (sanity-io/sanity, 6.4k stars) and Test Driven Development (farm-fe/farm, 5.6k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
