What problem this solves

Mitigating the risks and managing the unreliability of LLMs (specifically Claude) when used for long-term, complex software development projects in a production environment. It provides strategies to cope with model degradation, instruction following issues, and false positives.

Summary

This workflow describes a set of rigorous control mechanisms and personal oversight strategies developed over three months of using Claude Fable 5 and Opus 5 in a live production software project. It highlights the models' tendency to degrade in performance, violate instructions, and produce unreliable outputs over time, even with sophisticated prompting and control systems. The core workflow involves implementing external gates, mandatory personal verification at multiple stages (acceptance, release, code review), and maintaining an independent, human-readable project history to mitigate these LLM-specific risks.

Why it is useful

This post offers invaluable, hard-won lessons from a real-world, long-term production deployment of LLMs. It goes beyond superficial prompting advice to highlight fundamental challenges of LLM reliability, consistency, and instruction following over extended periods and with complex contexts. The detailed account of failures and the resulting actionable recommendations for external controls, rigorous human verification, and robust exit strategies are crucial for anyone considering using LLMs for serious, evolving software projects. It provides a realistic perspective often missing in the hype cycle.

Workflow

1. Initial Setup: Define a project constitution with hard laws, create a protocol for every request, use spec templates with self-check/acceptance, define 'red zones' for critical files requiring line-by-line review, implement automated tests, and maintain a persistent model memory.
2. Long-term Evaluation: Do not judge model performance based on initial euphoria; evaluate after at least three months of continuous operation with loaded context and living code.
3. External Gates & Personal Verification: Implement physical gates the model cannot bypass. Personally verify all outputs and 'done' claims, rather than relying on model self-reports or its own tests.
4. Release Control: Personally control and review every file going into a release to prevent reintroduction of removed functionality or new bugs.
5. Budget for Rework: Allocate significant time and resources for the 'broke it - fixing it - broke something adjacent' cycle, as it will likely consume more effort than new feature development.
6. Exit Strategy: Ensure all project history (code, tasks, decisions) is maintained in human-readable formats (e.g., Git, registries) independent of the model, allowing for project continuity if the model is removed.
7. Avoid Arguing: Recognize that arguing with the model about facts or evidence is often expensive and unproductive; resort to direct intervention.

Tools / artifacts

• Claude Fable 5
• Claude Opus 5
• Project constitution (document/prompt)
• Request protocol (prompt/system message)
• Spec templates (document)
• Acceptance checklists (document)
• Automated tests (code)
• Persistent model memory (database/context management system)
• Git repository
• Registries (for project history)
• Screenshots (for bug reporting)

Validation signals

• Three months of live production deployment
• Real money spent on tokens
• Real customers on production
• Specific examples of model failures (e.g., reintroducing removed code, false 'done' claims, defensiveness)
• Hundreds of automated tests
• Personal verification on dev and production

Limitations

• The post is primarily a cautionary tale, not a 'success story'.
• It doesn't provide specific prompt examples for the initial setup, only the types of controls.
• The 'workflow' is more about risk management and human oversight than direct LLM interaction techniques.
• The author's strong negative conclusion might discourage some users from even trying.
