gates

9-language quality gate validation: linting, formatting, type checking, and test execution. Validates code changes meet quality standards before completion. Use when: (1) after code implementation, (2) before PR creation, (3) as part of /orchestrator Step 6, (4) manual quality check. Triggers: /gates, 'quality gates', 'run validation', 'check quality', 'validate code'.

Gates - Quality Validation (v2.37)

Comprehensive quality validation across 9 programming languages with TLDR-assisted analysis.

Quick Start

/gates              # Run all quality gates
ralph gates         # Via CLI
ralph gates src/    # Specific directory

Pre-Gates: TLDR Language Detection (v2.37)

AUTOMATIC - Detect project languages efficiently:

# Get codebase structure to detect languages (95% token savings)
tldr structure . > /tmp/project-structure.md

# From structure, identify:
# - Primary language(s)
# - Config files present
# - Test frameworks used

Supported Languages

Language	Linter	Formatter	Types
TypeScript	ESLint	Prettier	tsc
JavaScript	ESLint	Prettier	-
Python	Ruff	Black	mypy
Rust	Clippy	rustfmt	cargo check
Go	golint	gofmt	go vet
Java	Checkstyle	google-java-format	-
Ruby	RuboCop	-	Sorbet
PHP	PHP_CodeSniffer	php-cs-fixer	PHPStan
Solidity	Solhint	prettier-solidity	-

Workflow

1. Detect Languages

# Auto-detect based on file extensions and config files

2. Run Linters

# Per-language linting
npx eslint src/          # TypeScript/JavaScript
ruff check .             # Python
cargo clippy             # Rust
golangci-lint run        # Go

3. Check Formatting

npx prettier --check .   # JS/TS
black --check .          # Python
rustfmt --check src/     # Rust
gofmt -l .               # Go

4. Type Checking

npx tsc --noEmit         # TypeScript
mypy .                   # Python
cargo check              # Rust
go vet ./...             # Go

5. Run Tests

npm test                 # Node projects
pytest                   # Python
cargo test               # Rust
go test ./...            # Go

Exit Codes

Code	Meaning
0	All gates passed
1	Lint errors
2	Format errors
3	Type errors
4	Test failures

Gate Configuration

Minimal (fast)

ralph gates --minimal    # Lint only

Standard (default)

ralph gates              # Lint + Format + Types

Full (CI)

ralph gates --full       # Lint + Format + Types + Tests

Integration

Invoked by /orchestrator in Step 6
Pre-step: tldr structure for language detection (v2.37)
Must pass before VERIFIED_DONE
Hooks:
```
quality-gates.sh
```
(PostToolUse)

TLDR Integration (v2.37)

Phase	TLDR Command	Purpose
Language detection	`tldr structure .`	Identify languages
Error context	`tldr context $FILE .`	Understand failing code
Impact analysis	`tldr deps $FILE .`	Find related tests

Anti-Patterns

Never skip gates for "quick fixes"
Never ignore type errors
Never commit with lint warnings
