Prevents overengineering through worthiness scoring, opportunity cost comparison, and branch threshold monitoring. Triggers: scope creep, overengineering, worthiness score, branch size, YAGNI, feature evaluation, scope validation, anti-overengineering, opportunity cost Use when: evaluating features during brainstorming, planning new functionality, branches approach size limits (1000/1500/2000 lines, 15/25/30 commits) DO NOT use when: feature is already approved and in progress. DO NOT use when: simple bug fixes with clear scope. Use this skill BEFORE implementing any new feature. This is NON-NEGOTIABLE for scope control.

modules/anti-overengineering.mdmodules/baseline-scenarios.mdmodules/branch-management.mdmodules/decision-framework.mdPrevents overengineering by both Claude and human during the brainstorm→plan→execute workflow. Forces explicit evaluation of every proposed feature against business value, opportunity cost, and branch constraints.
Core Belief: Not all features deserve implementation. Most ideas should be deferred to backlog until proven necessary.
Three Pillars:
Use the Worthiness formula:
(Business Value + Time Criticality + Risk Reduction) / (Complexity + Token Cost + Scope Drift)
See decision-framework.md for details.
Thresholds:
Compare against docs/backlog/queue.md:
Default: 3 major features per branch
If at capacity, must drop existing feature, split to new branch, or justify override.
Watch for Yellow/Red zones:

At end of brainstorming, before documenting design:
Self-invoke prompt: "Before documenting this design, let me evaluate the proposed features with scope-guard."
Before finalizing implementation plan:
Self-invoke prompt: "Before finalizing this plan, let me verify scope with scope-guard."
Periodically during execution:
Self-invoke prompt: "This branch has grown significantly. Let me check scope-guard thresholds."
When evaluating a feature, create these todos:

Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
