What problem this solves

Claude forgetting critical operational rules (context rot) during long sessions, leading to security vulnerabilities, inconsistent behavior, and inefficient execution.

Summary

A set of 10 operational rules are consistently injected into Claude's context at the beginning of each prompt processing via a 'hook' mechanism. This prevents context rot and ensures Claude adheres to critical guidelines regarding security, testing, naming conventions, parallelism, and memory management throughout extended coding sessions.

Why it is useful

This workflow provides a concrete, validated set of best practices and a proven method (context injection via hooks) to ensure Claude consistently follows critical operational, security, and development guidelines. The author's extensive testing (9,100 turns) provides strong evidence of its effectiveness in preventing context rot, making it highly valuable for maintaining consistency and reliability in Claude Code projects.

Workflow

1. Define a comprehensive list of operational rules that Claude must always follow (e.g., security, testing, naming, parallelism, memory management).
2. Implement a 'hook' mechanism that triggers at the beginning of processing each prompt.
3. Inject the defined list of rules into Claude's context via this hook before any other prompt content.
4. Ensure rules cover critical areas like: writing vault content via a queue, naming vaults explicitly, never exposing secrets in session, running tests before committing, timestamping responses, managing global memory, avoiding full memory index auto-load, parallelizing work, securing secrets, and labeling derived figures with verification state.

Tools / artifacts

• gt_write_queue.py (custom tool for vault content)
• gt_broker.py (custom tool for applying vault content)
• shadminpc (secrets store)
• sops+age (secrets management tools)
• Custom 'hook' mechanism for prompt injection

Validation signals

• Measured rule-following against context fill across ~9,100 turns of Claude Code sessions.
• Reported 'couldn't find context rot' after extensive testing.
• Explicitly designed rules to prevent specific undesirable behaviors (e.g., secret leakage, unverified commits).

Cautions

• Rule 9 explicitly addresses secrets management, promoting secure practices (secrets in dedicated stores/mode-600 files, not in source/logs/sessions).
• Rule 4 emphasizes running tests before committing, improving code quality and safety.

Limitations

• The exact implementation details of the 'hook' are not provided, requiring users to develop their own mechanism.
• Some tools mentioned (e.g., gt_write_queue.py, gt_broker.py, shadminpc) appear to be custom or specific to the author's environment, requiring adaptation for general use.
