Reliability Evidence Pack (REP)

A comprehensive runtime system for documenting and verifying agent operational reliability through structured artifact recording, validation, and compliance reporting.

What's Included

Core Scripts (/scripts)

• rep.mjs - Main CLI for initialization, validation, and bundle management
• rep-validate.mjs - Schema validation engine for REP artifacts
• rep-heartbeat-cron.mjs - Records agent heartbeats on a schedule
• rep-near-miss-cron.mjs - Tracks near-miss reliability events
• rep-performance-baseline.mjs - Captures performance metrics
• rep-generate-bundle.mjs - Generates REP bundles from artifacts

CLI Package (/cli)

• Installable npm package for convenient command-line access
• See cli/README.md for installation and usage

GitHub Action (/github-action)

• CI/CD integration for automated validation
• See github-action/README.md for setup

Schemas (/schemas)

• JSON Schema definitions for all REP artifact types:
  • decision_rejection_log.json
  • handoff_acceptance_packet.json
  • memory_reconstruction_audit.json
  • near_miss_reliability_trailer.json
  • signed_divergence_violation_record.json

Examples (/examples)

• Sample artifacts and workflows
• Integration patterns for different use cases

Required Binaries

• Node.js (v16 or higher - required for runtime scripts)
• npm (for CLI package installation)

No other system binaries required.

Installation

Option 1: Direct Scripts

# Clone or copy this bundle to your project
cp -r rep-bundle-v2 /path/to/your/project/rep
cd rep

# Make scripts executable
chmod +x scripts/*.mjs

# Test
node scripts/rep.mjs --help

Option 2: CLI Package

cd cli
npm install -g
rep --help

Option 3: GitHub Action

- uses: ./github-action
  with:
    bundle-path: ./rep

Configuration

Set environment variables to configure behavior:

# Path to artifacts directory (default: ./artifacts)
REP_ARTIFACTS_PATH=./artifacts

# Path to schemas directory (default: ./schemas)  
REP_SCHEMAS_PATH=./schemas

# Log file path (optional)
REP_LOG_FILE=/var/log/rep.log

Usage

Initialize a new REP

node scripts/rep.mjs init --name "my-agent"

Validate artifacts

node scripts/rep-validate.mjs ./artifacts --strict

Run heartbeat recording (cron)

REP_ARTIFACTS_PATH=./artifacts node scripts/rep-heartbeat-cron.mjs

Set up cron (example for crontab)

# Add to crontab - run heartbeat every 5 minutes
*/5 * * * * cd /path/to/rep && REP_ARTIFACTS_PATH=./artifacts node scripts/rep-heartbeat-cron.mjs >> /var/log/rep-heartbeat.log 2>&1

Artifact Types

Artifact	Purpose
agent_heartbeat_record	Agent lifecycle events
decision_rejection_log	Decisions and their outcomes
context_snapshot	Memory/context state
handoff_acceptance_packet	Inter-agent handoff validation
near_miss_reliability_trailer	Near-miss events
memory_reconstruction_audit	Memory integrity checks
signed_divergence_violation_record	Policy violations

Security Considerations

• Credentials: This skill does not require or handle credentials
• File Access: Writes to configured artifacts directory only
• Cron: Does not modify system crontab - operator must configure
• Logs: Optional logging to configurable path

Support

• Documentation: SPEC.md, QUICKSTART.md, INTEGRATION.md
• Examples: examples/
• Validation: node scripts/rep-validate.mjs --help

Security Considerations

Sensitive Data

REP captures context snapshots, decision logs, and memory-like artifacts that may contain sensitive information.

• Set REP_ARTIFACTS_PATH to an isolated, access-controlled directory
• Review or redact artifacts before sharing externally
• Consider running in a container or unprivileged account

Signing Keys

The SPEC includes signature fields for artifact integrity, but key management is operator-defined:

• Do NOT place private keys in the artifacts directory
• Use external KMS or secure vault for production signing
• For testing, generate keys externally and pass via environment (future feature)

CI Usage

The GitHub Action is local to your repository:

• Review github-action/entrypoint.sh before use in public CI
• Ensure no artifacts leak to external endpoints
• Use isolated artifact paths in CI environments

Network Behavior

All scripts operate locally:

• No telemetry or external API calls
• No automatic updates
• All file I/O is to configured artifact paths only

Best Practices

1. Keep artifacts directory separate from source code
2. Add artifact paths to .gitignore
3. Rotate logs regularly
4. Audit artifacts before external sharing
