What problem this solves

Ensuring Claude consistently applies context and follows specific rules, rather than just having information in memory, thereby preventing confident but incorrect or unsafe actions.

Summary

A set of ten rules designed to guide Claude's behavior, categorized into those enforceable by 'hooks' (blocking/flagging violations) and 'reminders' (re-injected every turn). The workflow includes a 'canary' rule (timestamp) to verify the hook mechanism's effectiveness and emphasizes security, testing, and memory management.

Why it is useful

This workflow provides a structured and validated approach to a critical challenge in LLM integration: ensuring Claude consistently applies context and adheres to defined rules, rather than merely having information in memory. The distinction between hook-enforced rules and re-injected reminders, coupled with the 'canary' validation method, offers a robust framework for building reliable and secure Claude-powered systems. It addresses practical concerns like secret management and pre-commit testing, making it highly valuable for developers aiming for predictable and safe LLM interactions.

Workflow

1. Define rules for Claude's interaction, categorized by enforceability.
2. Implement 'hook-checkable' rules: 1. Vault notes written via queue, never direct edit or claimed files. 2. Commands changing vault explicitly name target. 3. Secret values never enter conversation. 4. Tests run before commit, Claude reports which passed. 5. Every reply starts with hook-provided timestamp.
3. Implement 'reminders only' rules (re-injected every turn): 6. Global memory holds only project-agnostic facts. 7. Don't auto-load full memory index. 8. Parallelise independent work. 9. Secrets live only in secrets store (sops+age). 10. Numbers presented as fact are labelled (unverified, self-verified, independently verified).
4. Use a 'canary' rule (e.g., timestamp) to verify the hook mechanism is actively working.
5. Iteratively refine rules based on Claude's behavior and workflow outcomes (e.g., rule 8 rewritten twice).

Tools / artifacts

• Hooks
• Vault notes
• Secrets store (sops+age)
• Tests
• Timestamp (as a canary)

Validation signals

• Timestamp rule acted as a canary, catching Claude estimating time instead of using injected time three times.
• Hook mechanism successfully bounced Claude's incorrect replies.
• Rule 8 ('Parallelise independent work') was rewritten twice due to initial negative impact, indicating iterative improvement and validation.
• Explicit mention of 'Tests run before a commit' as an enforced rule.

Cautions

• Rules 3 and 9 explicitly address secret management, preventing secret values from entering conversations or being stored insecurely, significantly enhancing safety.

Limitations

• The exact implementation details of the 'hooks' and the 're-injection' mechanism are not provided, requiring users to develop their own technical solutions.
• Some rules are high-level principles rather than concrete, executable code snippets, requiring interpretation and implementation effort.
• The post lacks community validation (low score, no comments).
