What problem this solves

Loss of project context and state across different Claude chat sessions, leading to repetitive explanations and inefficient interactions.

Summary

A detailed prompt for Claude to create a 'persistent project brain' skill. This skill establishes a structured set of files (SKILL.md, STATE.md, topic files) or uses Claude's custom instructions and knowledge documents to maintain project context, state, and rules across chat sessions. It includes self-update mechanisms and a readiness check to ensure Claude always has the most current and verified project information.

Why it is useful

This workflow provides a highly structured and detailed method for overcoming a fundamental limitation of LLMs: their stateless nature across conversations. By defining explicit file structures, update rules, and a 'readiness check,' it enables Claude to maintain a consistent and verified understanding of a project's state, history, and future steps. It offers a robust solution for both local filesystem and claude.ai users, significantly enhancing efficiency and reducing the need for repetitive context setting. The self-correction and verification rules embedded in the prompt further increase its reliability.

Workflow

1. Provide the detailed prompt to Claude.
2. Answer Claude's initial questions (brain name, project details, existing work).
3. If using Claude Code with a filesystem, Claude creates a .claude/skills/<name>/ directory containing SKILL.md, STATE.md, and topic files.
4. If using claude.ai without a filesystem, Claude provides content for Custom Instructions and a STATE.md knowledge document.
5. If without a filesystem, manually update Custom Instructions and re-upload the STATE.md knowledge document after each significant session.
6. Use the created skill/setup for ongoing project work.
7. Claude updates STATE.md after meaningful work or on session wrap-up, based on defined rules.
8. Claude edits topic files when new information contradicts existing facts.
9. Review Claude's output and verify work before marking it as 'confirmed working' in STATE.md.

Tools / artifacts

• Claude AI (Claude Code or claude.ai)
• Prompt (the provided text)
• .claude/skills/<name>/ directory (for filesystem)
• SKILL.md file
• STATE.md file
• Topic files (e.g., subsystem_a.md)
• Readiness check script (for filesystem)
• Custom Instructions (for no filesystem)
• Project knowledge document (for no filesystem)

Validation signals

• Author's claim: 'very surprised at how well its been able to keep track of my project and changes I make.'
• Built-in 'readiness check' script to verify project readiness.
• Rules for updating STATE.md only after 'something got built, proved, rejected, or decided.'
• Rule: 'Do not write 'it works' anywhere until I have seen it work with my own eyes.'
• Rule: 'Unverified goes in AS unverified, unently omitted, never stated as fact.'

Limitations

• The manual re-upload of STATE.md for the claude.ai (no filesystem) version is a significant point of friction and potential for context decay.
• Relies heavily on Claude's ability to consistently follow complex, multi-part instructions over time, which can vary.
• The prompt contains several typos and incomplete sentences (e.g., 'DECOY paths,be trusted.', 'reports the result without be', 'whethdump the state file', 'project-s whatever I have already told you;'), which could potentially confuse Claude during skill generation.
• Lack of community validation or success reports beyond the author's initial claim.
