What does this agent skill do?
Subtract Before You Add
When evolving a system, remove complexity first, then build.
Why: Adding to a complex system compounds complexity. Removing first leaves less code, reveals the essential structure, and usually makes the next design obvious. Default to subtraction.
Make simplification a continual investment. Leave the design slightly simpler and more capable behind the same or smaller surface than you found it.
The pattern:
- Sequence removal before construction
- Cut before you polish (get to the minimum before investing in quality)
- Design for observed usage, not speculative edge cases
- No speculative validators, parsers, or guards beyond what the spec demands
- Simplify prompts (remove redundant instructions, excessive templates)
- When a reference has no novel content, delete it rather than leaving a stub
