A command that carries out the full Test-Driven Development process for a feature or function.

Use it to define types, write failing tests, implement the minimum code, refactor it, and check that test coverage reaches at least 80%.

It structures implementation around tests, reducing uncertainty about whether the finished code handles normal cases, edge cases, and errors.

tdd — Command for Claude Code and Cursor by jy315189/everything-cursor

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/jy315189/everything-cursor

Made for: Claude Code, Cursor.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 211 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00211
Opus 5.5	$0.00000	$0.00084
Sonnet 5.5	$0.00000	$0.00042
Haiku 4.5	$0.00000	$0.00021

Security

Grade A, and why

tdd scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

/tdd — Test-Driven Development

Execute the complete TDD workflow for a feature or function.

When to Use

Implementing a new function, service, or API endpoint
You want tests to drive the design
You need high confidence that the implementation is correct

Input

Describe the feature or function to implement:

/tdd [feature description]

What Happens

Define — Creates TypeScript interface/types for the feature
RED — Writes comprehensive failing tests (happy path + edge cases + errors)
GREEN — Implements minimal code to pass all tests
REFACTOR — Improves code quality while keeping tests green
COVERAGE — Verifies ≥80% coverage

Example

/tdd Create a calculateDiscount function that applies percentage and fixed discounts with a max discount cap

Delegates to: @agents/tdd-guide for step-by-step cycle guidance

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tdd is a command published in the GitHub repository jy315189/everything-cursor (2 stars, last pushed 9mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 211 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
