Initialize the orchestrator with an API key and execute an agent.

from bernstein import Orchestrator import os orc = Orchestrator( api_key=os.environ.get('BERNSTEIN_API_KEY', ''), audit_log='./audit.chain' ) result = orc.execute( agent='claude-code', prompt='Refactor the database module', context={'repo': './app'} ) print(result.artefact_id) print(result.audit_hash)

Debug

Known issues

breakingIn version 2.0.0, the 'agent' parameter changed from string to enum-like Agent enum. Using raw strings may break or be deprecated.

fix

Use Agent.CLAUDE_CODE instead of 'claude-code'.

affects: >=2.0.0

gotchaThe audit log is HMAC-chained by default; attempting to modify the log file will break the chain. Do not edit the file manually.

fix

Use the provided API (AuditLog.verify()) to validate integrity.

affects: all

deprecatedThe 'verbose' parameter in Orchestrator is deprecated since 2.5.0 and will be removed in 3.0.0.

fix

Use logging configuration with standard Python logging.

affects: >=2.5.0
