trustlint 2.0.3

Offline compliance linter for AI agents — scans text against the ComplyEdge rule corpus

TrustLint

Offline compliance linter for AI agents — scans text against the ComplyEdge rule corpus using Tier 1 regex patterns. No API key required.

Catches EU AI Act, SOX, HIPAA, GDPR, COPPA, and PCI DSS violations before they reach production.

Installation

pip install trustlint

Quick Start

# Check text for compliance violations
trustlint check --text "We expect revenue to increase by 25% next quarter"

# Check a file
trustlint check prompt.txt

# Pipe from stdin
echo "Deploy social credit score for citizens" | trustlint check

# Filter by jurisdiction
trustlint check --text "social credit score" --jurisdiction EU

# Verbose output (citations + remediation)
trustlint check --text "earnings forecast" -v

Commands

trustlint check

Scan text for compliance violations against the loaded rule corpus.

trustlint check --text "your AI prompt here"    # Check a string
trustlint check myfile.py                        # Check a file
trustlint check --text "text" -j EU             # Filter to EU rules only
trustlint check --text "text" -v                 # Verbose: show citations

Exit codes:

• 0 — No critical/high violations (CI pass)
• 1 — Critical or high severity violations found (CI fail)
• 2 — Input error (missing file, no rules loaded)

trustlint rules list

Show all loaded compliance rules with severity and jurisdiction.

trustlint rules list              # All rules
trustlint rules list -j US        # US rules only

trustlint init

Create a .trustlint.yaml configuration file in the current directory.

trustlint init           # Create config
trustlint init --force   # Overwrite existing

Example Output

TrustLint Report
────────────────────────────────────────────────────────────

[CRITICAL] SOX_HYBRID_MATERIAL_DISCLOSURE_001
  Hybrid SOX Material Information Disclosure Prevention
  Jurisdiction: US | Matched: Forward-looking statements requiring analysis

────────────────────────────────────────────────────────────
1 critical/high, 0 medium/low (12 rules evaluated)

How It Works

TrustLint loads YAML rule files from the ComplyEdge rule corpus (rules/regulations/). Each rule contains regex patterns for Tier 1 (fast, deterministic) detection. The engine:

1. Loads all .yaml rule files from the rules directory
2. Extracts regex conditions and hybrid_detection.tier1_config.risk_flag_patterns
3. Matches patterns against the input text
4. Reports violations with rule ID, severity, jurisdiction, and citation

No API calls are made in offline mode. For deeper Tier 2 LLM analysis, set the COMPLYEDGE_API_KEY environment variable (requires a ComplyEdge account).

CI/CD Integration

GitHub Actions

- name: Compliance check
  run: |
    pip install trustlint
    trustlint check --text "${{ github.event.pull_request.body }}"

Pre-commit hook

#!/bin/sh
trustlint check "$1" || exit 1

Rules Coverage

Jurisdiction	Regulations	Examples
EU	EU AI Act Article 5	Social scoring, subliminal manipulation, biometric categorisation
US	SOX, HIPAA, COPPA, TCPA	Material disclosure, PHI protection, child data
Global	PCI DSS	Payment card data detection

Configuration

Create .trustlint.yaml with trustlint init:

# Rules directory (default: auto-detect)
# rules_dir: ./rules/regulations

# Default jurisdiction filter
# jurisdiction: EU

# Severity threshold
# severity_threshold: medium

Development

# Install in development mode
pip install -e packages/trustlint/

# Run tests
