Template Management

template_lifecycle:
  creation:
    - Define variables and placeholders
    - Set defaults for optional params
    - Add validation rules
    - Document usage

  usage:
    - Load template
    - Validate variables
    - Substitute placeholders
    - Return final prompt

  maintenance:
    - Version templates
    - Track usage metrics
    - A/B test variants
    - Deprecate outdated

Optimization Patterns

Token Reduction

optimization:
  remove_redundancy:
    before: "Please kindly ensure that you carefully..."
    after: "Ensure you..."

  use_lists:
    before: "Check for security issues. Also check for performance. And check for quality."
    after: |
      Check for:
      - Security issues
      - Performance
      - Quality

  template_variables:
    before: "You are a Python expert reviewing Python code for Python best practices"
    after: "You are a {language} expert reviewing code for best practices"

Validation

validation_checklist:
  structure:
    - [ ] All variables are documented
    - [ ] Defaults provided for optional vars
    - [ ] Clear output format specified

  quality:
    - [ ] Tested with real data
    - [ ] Edge cases handled
    - [ ] Error messages helpful

  maintenance:
    - [ ] Version tracked
    - [ ] Usage documented
    - [ ] Examples provided

Troubleshooting

| Issue | Cause | Solution | |-------|-------|----------| | Missing variable | Undeclared placeholder | Check variable names | | Wrong output | Template mismatch | Verify output format | | Too verbose | Redundant text | Optimize template | | Inconsistent | Multiple variants | Standardize templates |
