Overview

Agent keys are the PRIMARY and EXCLUSIVE authentication method for all CLI commands and workers. JWT tokens are ONLY used during the login process.

What is an Agent Key?

Agent keys are API keys with the prefix anyt_agent_ that provide persistent authentication for:

CLI commands (anyt task list, etc.)
Worker processes (anyt worker run)
Workflow execution and attempt tracking
Artifact creation

Why Agent Keys?

Clarity: Clear separation between agent keys (CLI/workers) and JWT tokens (login only)
Consistency: All operations use the same authentication method
Security: Agent keys are explicitly named and prioritized
Simplicity: No confusion about which auth method to use

Quick Start

For New Users

# 1. Get your agent API key from https://anyt.dev/home/settings/api-keys
export ANYT_API_KEY="anyt_agent_your_key_here"

# 2. Use CLI
anyt task list
anyt worker start --agent-id agent-xxx

Environment Variables

# Required: Agent API key
export ANYT_API_KEY="anyt_agent_..."

Migration Guide

Configuration Priority

The system loads configuration in this priority order (highest to lowest):

ANYT_AGENT_KEY environment variable (highest)
Workspace config (.anyt/anyt.json) - agent_key field
Global config (~/.config/anyt/config.json) - agent_key field
ANYT_AUTH_TOKEN environment variable (lowest, auto-migrates if starts with anyt_agent_)

Auto-Migration

Old configurations are automatically migrated: Before:

{
  "environments": {
    "dev": {
      "auth_token": "anyt_agent_old_key",
      "agent_key": null
    }
  }
}

After (auto-migrated):

{
  "environments": {
    "dev": {
      "auth_token": null,
      "agent_key": "anyt_agent_old_key"
    }
  }
}

Testing

# ✅ New way (preferred)
export ANYT_TEST_AGENT_KEY="anyt_agent_test_key"
PYTHONPATH=src uv run pytest tests/cli/integration/ -v

# ✅ Legacy way (still works, auto-migrates)
export ANYT_TEST_TOKEN="anyt_agent_test_key"
PYTHONPATH=src uv run pytest tests/cli/integration/ -v

Architecture

Authentication Flow

User/Worker Request
    ↓
Load Config (with priority: ANYT_AGENT_KEY > workspace > global > ANYT_AUTH_TOKEN)
    ↓
Create API Client with agent_key
    ↓
Build HTTP Headers
    ↓
Add X-API-Key header (if agent_key exists)
    OR
Add Authorization header (if no agent_key, JWT token only)
    ↓
Make API Request

Configuration Files

Workspace Config (.anyt/anyt.json):

{
  "workspace_id": 123,
  "workspace_name": "Production",
  "workspace_identifier": "PROD",
  "api_url": "https://api.anyt.dev",
  "current_project_id": 456
}

Note: API keys are stored in environment variables only, never in config files.

Fixes Implemented

This section documents the three major fixes implemented to support agent key authentication throughout the codebase.

Fix 1: Attempt Workflow Start/Finish

Problem: Coordinator was calling generated API services without passing agent key, causing “Header value must be str or bytes, not <class 'NoneType'>” errors. Solution: Updated src/cli/worker/coordinator.py:

Added _load_agent_key() method to load agent key from config
Added _get_api_config() method to load API URL from config

Updated _start_attempt() to pass both parameters:

api_config = self._get_api_config()
response = await start_attempt_v1_tasks__identifier__attempts_start_post(
    api_config_override=api_config,
    identifier=task_identifier,
    data=attempt_input,
    workspace_id=workspace_id,
    X_API_Key=self.agent_key,
)

Updated _finish_attempt() similarly

Files Modified: src/cli/worker/coordinator.py

Fix 2: Authentication System Refactoring

Problem: Mixed authentication with unclear priority between agent keys and JWT tokens. Solution: Refactored entire authentication system: src/cli/config.py - Updated get_effective_config():

Agent key now takes absolute priority over JWT tokens
Auto-migrates agent keys stored in wrong field
Clear documentation about auth_token being login-only

src/cli/client/adapter.py - Updated _build_headers_for_request():

Changed order: Check agent_key FIRST, then auth_token as fallback
Always uses X-API-Key header if agent key present

src/cli/commands/auth.py - Updated login command:

Agent keys now stored in agent_key field (not auth_token)
Auto-detects if provided token is agent key vs JWT
Clears old auth_token when storing agent key

tests/cli/integration/conftest.py - Updated test fixtures:

Checks ANYT_TEST_AGENT_KEY first
Auto-detects and stores in correct field
Backward compatible with ANYT_TEST_TOKEN

Fix 3: Artifact Creation

Problem: Workflow executor failed to create artifacts with same “Header value must be str or bytes” error. Solution: Updated src/cli/worker/executor.py:

Added agent_key parameter to WorkflowExecutor.__init__()
Added _get_api_config() method

Updated artifact creation calls to pass both parameters:

api_config = self._get_api_config()
await create_artifact_v1_attempts__attempt_id__artifacts__post(
    api_config_override=api_config,
    attempt_id=attempt_id,
    data=CreateArtifactInput(...),
    X_API_Key=self.agent_key,
)

Updated src/cli/worker/coordinator.py:

Moved agent key loading before executor initialization
Pass agent_key to executor constructor

Files Modified: src/cli/worker/executor.py, src/cli/worker/coordinator.py

Developer Reference

Pattern for Generated API Calls

When using any generated API service function, ALWAYS pass:

api_config_override=self._get_api_config() - for correct base URL
X_API_Key=self.agent_key - for agent authentication

Example:

# Get API config
api_config = self._get_api_config()

# Call generated service
await some_generated_api_function(
    api_config_override=api_config,
    # ... other parameters ...
    X_API_Key=self.agent_key,
)

Helper Method Template

Add this method to any class that calls generated API services:

def _get_api_config(self) -> Any:
    """Get APIConfig for generated API client calls."""
    try:
        from cli.config import GlobalConfig
        from sdk.generated.api_config import APIConfig

        config = GlobalConfig.load()
        effective_config = config.get_effective_config()
        api_url = effective_config.get("api_url")

        if not api_url:
            raise RuntimeError("API URL not configured")

        return APIConfig(base_path=api_url, access_token=None)
    except Exception as e:
        console.print(f"[yellow]Warning: Failed to load API config: {e}[/yellow]")
        from sdk.generated.api_config import APIConfig
        return APIConfig()

Integration Test Examples

See tests/cli/integration/test_attempt_workflow_agent_auth.py for comprehensive examples of:

Testing with agent key authentication
Testing JWT token authentication (legacy)

Common issues and fixes

Common Issues

Issue 1: “Request URL is missing protocol”

Symptom:

Warning: Failed to start attempt: Request URL is missing an 'http://' or 'https://' protocol.

Cause: API URL configuration issue Fix:

# Verify workspace configuration
cat .anyt/anyt.json

# Ensure workspace is properly initialized
anyt init --workspace-id 123 --identifier PROD

Issue 2: “Header value must be str or bytes, not `<class 'NoneType'>`”

Symptom:

Warning: Failed to start attempt: Header value must be str or bytes, not <class 'NoneType'>

Cause: Agent key not loaded or not passed to generated API calls Fix:

Ensure agent key is set:

export ANYT_AGENT_KEY="anyt_agent_your_key"
# OR
anyt auth login --agent-key anyt_agent_your_key

If still failing, check that the code passes X_API_Key=self.agent_key to generated API calls

Issue 3: “Missing authentication credentials”

Symptom:

Warning: Failed to update task status: Missing authentication credentials

Cause: No agent key configured Fix:

# Set agent key
anyt auth login --agent-key anyt_agent_your_key

# Verify
cat ~/.config/anyt/config.json | jq '.environments.dev.agent_key'

Verification Commands

# Check code works
PYTHONPATH=src uv run python -c "from cli.client.adapter import GeneratedClientAdapter; print('✅ OK')"

# Check config
cat ~/.config/anyt/config.json | grep agent_key

# Check workspace config
cat .anyt/anyt.json | jq '.agent_key'

# Run debug script
./scripts/debug_config.sh

# Test worker
anyt worker run
# Should see: ✓ Started attempt #123

Testing

Test Attempt Workflow

Use the test script to verify attempt workflow:

./scripts/test_attempt_workflow.sh

Manual Testing

# Set environment
export ANYT_API_KEY="anyt_agent_test_key"

# Test CLI commands
anyt task list
anyt board

# Run worker
anyt worker start --agent-id agent-test

Production Security Best Practices

Key Management

1. Agent Key Storage

Production Environment:

# Option 1: systemd service (recommended for production)
[Service]
Environment="ANYT_API_KEY=anyt_agent_xxx"
EnvironmentFile=/etc/anyt/secrets.env  # Better: separate file with restricted permissions

# Option 2: Separate secrets file
# /etc/anyt/secrets.env (chmod 600, owned by service user)
ANYT_API_KEY=anyt_agent_production_xxx_yyy_zzz

Multi-Environment Setup:

# Use different environment variables per environment

# Staging
export ANYT_API_KEY="anyt_agent_staging_xxx"

# Production
export ANYT_API_KEY="anyt_agent_prod_xxx"

2. Key Rotation

Implement regular key rotation to minimize security risk: Rotation Procedure:

# 1. Generate new agent key via admin panel
#    Visit: https://anyt.dev/home/agents
#    Create new agent: "worker-prod-2025-02"

# 2. Test new key in staging
export ANYT_API_KEY=anyt_agent_new_xxx
anyt task list  # Verify authentication works

# 3. Update production configuration
# Edit /etc/anyt/secrets.env
ANYT_API_KEY=anyt_agent_new_xxx

# 4. Reload worker service
sudo systemctl restart anyt-worker

# 5. Verify worker is running
sudo systemctl status anyt-worker
anyt timeline  # Check for new attempts

# 6. Revoke old key (after 24-48 hours)
# Via admin panel: Revoke "worker-prod-2025-01"

Recommended Rotation Schedule:

Production: Every 90 days
Staging: Every 180 days
Development: As needed

3. Key Scoping

Use different agent keys for different purposes:

# Separate keys by environment
anyt_agent_prod_features_xxx      # Production feature development
anyt_agent_prod_bugs_xxx          # Production bug fixes
anyt_agent_staging_xxx            # Staging environment
anyt_agent_dev_xxx                # Development environment

# Separate keys by team
anyt_agent_team_frontend_xxx      # Frontend team
anyt_agent_team_backend_xxx       # Backend team
anyt_agent_team_devops_xxx        # DevOps team

# Development
anyt env use dev
anyt worker start --agent-id agent-dev

# Staging
anyt env use staging
anyt worker start --agent-id agent-staging

# Production (via systemd)
sudo systemctl start anyt-worker-prod

Security Hardening

File Permissions

Secrets File:

# Create secrets file with restricted permissions
sudo touch /etc/anyt/secrets.env
sudo chmod 600 /etc/anyt/secrets.env
sudo chown anyt-worker:anyt-worker /etc/anyt/secrets.env

# Add secrets
sudo -u anyt-worker bash -c 'cat > /etc/anyt/secrets.env << EOF
ANYT_API_KEY=anyt_agent_production_xxx
ANYT_API_URL=https://api.anyt.dev
AGENT_ID=agent-prod-001
EOF'

# Verify permissions
ls -la /etc/anyt/secrets.env
# Output: -rw------- 1 anyt-worker anyt-worker 123 Nov 14 12:00 /etc/anyt/secrets.env

Service User:

# Create dedicated service user
sudo useradd -r -s /bin/bash -d /var/lib/anyt anyt-worker
sudo mkdir -p /var/lib/anyt
sudo chown anyt-worker:anyt-worker /var/lib/anyt

# Project directory permissions
sudo chown -R anyt-worker:anyt-worker /opt/projects/production
sudo chmod 750 /opt/projects/production

Network Security

Firewall Rules:

# Allow outbound HTTPS only to API endpoint
sudo ufw allow out to api.anyt.dev port 443 proto tcp

# Deny other outbound traffic (if using strict firewall)
sudo ufw default deny outgoing

API Rate Limiting:

# Monitor rate limits
# Check response headers: X-RateLimit-Remaining

# Implement backoff in workflows if approaching limits

Audit Logging

Enable System Audit:

# Configure auditd to track worker actions
sudo auditctl -w /etc/anyt/secrets.env -p ra -k anyt_secrets
sudo auditctl -w /opt/projects/production -p wa -k anyt_worker_writes

# View audit logs
sudo ausearch -k anyt_secrets
sudo ausearch -k anyt_worker_writes

Worker Activity Logging:

# Configure structured logging
[Service]
StandardOutput=journal
StandardError=journal
SyslogIdentifier=anyt-worker-prod

# View logs with context
journalctl -u anyt-worker-prod -o json-pretty
journalctl -u anyt-worker-prod --since "1 hour ago" -f

Monitoring and Alerting

Authentication Monitoring

Failed Authentication Tracking:

# Monitor for authentication failures
journalctl -u anyt-worker-prod | grep -i "authentication\|unauthorized\|403\|401"

# Set up alerting for repeated failures
# Example: Prometheus + Alertmanager

Metrics to Track:

Authentication success/failure rate
API key expiration warnings
Unusual API access patterns
Failed attempt creation rate
Artifact upload failures

Security Alerts

Alert Conditions:

# Example: Alertmanager configuration
groups:
  - name: anyt_worker_security
    rules:
      - alert: HighAuthenticationFailureRate
        expr: rate(anyt_auth_failures_total[5m]) > 0.1
        for: 5m
        annotations:
          summary: "High authentication failure rate for worker"

      - alert: AgentKeyExpiringSoon
        expr: anyt_agent_key_expiry_days < 7
        annotations:
          summary: "Agent key expiring in {{ $value }} days"

      - alert: UnauthorizedAPIAccess
        expr: increase(anyt_api_unauthorized_total[10m]) > 5
        annotations:
          summary: "Potential unauthorized API access attempt"

Compliance Considerations

SOC 2 / ISO 27001

Access Control:

✅ Role-based access to agent keys
✅ Audit logging of key access
✅ Regular key rotation (90-day cycle)
✅ Separation of duties (dev/staging/prod)

Data Protection:

✅ Secrets stored in system keyring (encrypted at rest)
✅ TLS for all API communications (encrypted in transit)
✅ No secrets in logs or workflow files
✅ Artifact encryption support

Audit Trail:

# Complete audit trail via attempt tracking
anyt attempt list DEV-123        # Who executed what
anyt attempt show attempt-456    # When and how
anyt artifact list attempt-456   # What was produced
anyt timeline DEV-123            # Complete history

Data Minimization:

Only store necessary task data in workflows
Avoid logging personal information
Use artifact retention policies
Implement data deletion workflows

Access Logging:

# Track who accessed what data
journalctl -u anyt-worker-prod | grep "artifact download"
journalctl -u anyt-worker-prod | grep "task detail"

Secret Management Integration

HashiCorp Vault Integration

Example Integration:

# Fetch agent key from Vault
export ANYT_API_KEY=$(vault kv get -field=api_key secret/anyt/worker/prod)

# Or in systemd service
[Service]
ExecStartPre=/usr/local/bin/vault-get-secrets.sh
EnvironmentFile=/run/anyt/secrets.env  # Populated by vault-get-secrets.sh

Vault Get Secrets Script (/usr/local/bin/vault-get-secrets.sh):

#!/bin/bash
set -euo pipefail

# Authenticate with Vault
export VAULT_ADDR="https://vault.company.com"
vault login -method=aws -path=prod

# Fetch secrets
ANYT_API_KEY=$(vault kv get -field=api_key secret/anyt/worker/prod)

# Write to temporary file (tmpfs)
cat > /run/anyt/secrets.env << EOF
ANYT_API_KEY=${ANYT_API_KEY}
EOF

chmod 600 /run/anyt/secrets.env

AWS Secrets Manager Integration

# Fetch from AWS Secrets Manager
export ANYT_API_KEY=$(aws secretsmanager get-secret-value \
    --secret-id anyt/worker/prod/api-key \
    --query SecretString \
    --output text | jq -r .api_key)
