A command that enforces test-driven development for Laravel 13 applications using Pest 4. Test-driven development means writing a failing test before the code, then making it pass and cleaning up the result.

Use it when building Laravel features with HTTP, database, authentication, unit, or architecture tests, and when checking work before committing.

It provides a repeatable testing cycle and checks for feature behavior, isolated logic, architecture rules, code style, static-analysis issues, and coverage.

Per session 13 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 333 The whole file, excluding the scripts and references it only reads on demand.

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	$0.00013	$0.00333
Opus 5.5	$0.00005	$0.00133
Sonnet 5.5	$0.00003	$0.00067
Haiku 4.5	$0.00001	$0.00033

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 1mo 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 Command

Usage

Enforce a Test-Driven Development workflow using Pest 4 for Laravel 13 features.

TDD Cycle

RED — Write a failing test first
GREEN — Write minimal implementation to pass
REFACTOR — Clean up while keeping tests green

Test Structure

tests/
  Feature/       — 80% of tests (HTTP, database, auth)
  Unit/          — 20% of tests (Actions, DTOs, Services)
  Architect/     — Architecture enforcement tests

Test Types

Feature tests: Full request/response cycle with RefreshDatabase
Unit tests: Isolated logic for Actions, DTOs, Value Objects
Architecture tests: Enforce conventions with Pest ->arch()

Coverage Target

php artisan test --parallel --coverage --min=80

Before Committing

Write failing test (RED)
Write implementation (GREEN)
Refactor if needed (REFACTOR)
Run ./vendor/bin/pint --test
Run ./vendor/bin/phpstan analyse --level=6
Verify 80%+ coverage

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.

It adds 13 tokens to every session and 333 once invoked, about $0.0001 per session on Opus 5.5. 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.
