tdd

tdd is a command for Cursor from jy315189/everything-cursor. It costs 0 tokens per session (211 once invoked), scanned A, original, MIT.

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

In plain words
What is it for?
Use it to define types, write failing tests, implement the minimum code, refactor it, and check that test coverage reaches at least 80%.
Why use it?
It structures implementation around tests, reducing uncertainty about whether the finished code handles normal cases, edge cases, and errors.

Made for: 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. Scan, not verified.
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.

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 3d 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

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

Example

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

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 6mo 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.
