What it does
TDD Workflow is an agent skill from mohitagw15856/pm-claude-skills. Drive a feature with a disciplined test-driven development loop — red, green, refactor. Use when implementing a feature or fixing a bug and you want tests to lead, or when asked to 'do this with TDD' / write the test first. Produces a step-by-step red-green-refactor plan: the failing test to write first, the minimal code to pass it, and the refactor — one small cycle at a time.
Its SKILL.md is about 810 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: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Implementing a feature
- Fixing a bug and you want tests to lead
- Asked to do this with TDD / write the test first
Example prompts
- “do this with TDD”
- “/tdd-workflow”
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. 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 Workflow loads about 805 tokens when it runs. Until then it costs about 98 tokens; SKILL.md has 415 words of instructions outside code blocks.
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.

- description
- Drive a feature with a disciplined test-driven development loop — red, green, refactor. Use when implementing a feature or fixing a bug and you want tests to lead, or when asked to 'do this with TDD' / write the test first. Produces a step-by-step red-green-refactor plan: the failing test to write first, the minimal code to pass it, and the refactor — one small cycle at a time.
TDD Workflow Skill
The failure mode of AI-assisted coding is writing a pile of code, then maybe some tests that rubber-stamp it. TDD inverts that: the test defines the behavior first, the code does the minimum to pass, then you refactor safely. This skill runs that loop with discipline — one small red-green-refactor cycle at a time, never jumping ahead to untested code.
Required Inputs
Ask for these only if they aren't already provided:
- The behavior to build — the feature/bugfix, stated as observable behavior (input → expected output).
- The stack — language, test framework/runner, where tests live.
- The seam — the function/module/endpoint under test, and any collaborators to fake/mock.
- Edge cases — the conditions that matter (errors, empty, boundaries).
Output Format
TDD plan: [behavior]
Behavior list — the observable cases to drive out, ordered simplest → richest (happy path first, then edges/errors). Each becomes one cycle.
Then, for each cycle (do them one at a time, smallest first):
🔴 Red — the single failing test to write now (the actual test code), and why it fails (the behavior doesn't exist yet). One assertion of one behavior.
🟢 Green — the minimal code to make exactly that test pass — even if it's obvious/ugly. No extra features, no speculative generality.
🔵 Refactor — what to clean up now that it's green (naming, duplication, structure) with the test as the safety net. Skip if nothing's needed.
Run — the command to run the test(s) and what "passing" looks like.
End with: the next cycle's red test, and a note to commit at each green.

Quality Checks
- Behaviors are listed and ordered simplest-first; each cycle tests ONE behavior
- The red step writes a genuinely failing test before any implementation
- The green step is the minimal code to pass — no untested extra functionality
- Refactoring happens only on green, with tests as the safety net
- Edge/error cases each get their own cycle, not bolted onto the happy path
Anti-Patterns
- Do not write the implementation first and the test after — that's not TDD, it's rationalization
- Do not write five tests then all the code — one red→green→refactor cycle at a time
- Do not over-build in green — only enough to pass the current test
- Do not test implementation details — test observable behavior so refactors don't break tests
- Do not skip the refactor step when there's obvious duplication or a bad name
Based On
Test-Driven Development (Kent Beck): red → green → refactor, triangulation, one behavior per cycle.
Example Trigger Phrases
- "Implementing a feature."
- "Fix a bug and you want tests to lead."
- "'do this with TDD' / write the test first."
