Error Memory

Document errors to avoid repeating them.

Trigger

Invoke when:

• Build/tests fail after your action
• User corrects you
• You realize a wrong approach
• You forget a project convention
• Unexpected behavior occurs

Process

1. Identify error type

- tech : build, tests, syntax, runtime - ctx : conventions, patterns, project stack - comp : misunderstood requirements

1. Analyze root cause (not symptom)

1. Formulate fix as reusable rule

1. Append line to .claude/errors.md:

``markdown | MM-DD | type | Short error | Root cause | Rule to follow | ``

1. Create file if missing with this template:

```markdown # Project Errors

> Past Claude mistakes on this project. Check before acting.

## Legend - tech : Technical (build, tests, syntax) - ctx : Context (conventions, patterns) - comp : Comprehension (misunderstood request) ```

Rules

• One line = one error (no paragraphs)
• Fix = actionable rule, not excuse
• Cause = why, not what
• Keep < 100 lines (archive if needed)
• Check errors.md before acting on any project
