Applies Chesterton's Fence, Occam's Razor, the Peter Principle, and Dunning-Kruger to technical decisions. Use before refactoring, architectural changes, or any task where changing existing behavior carries risk or requires judgment about what the user actually needs.

engineering-judgment

Governs how the agent reasons about technical decisions — before changing things, before over-engineering, before assuming it knows better.

The Laws

  • Chesterton's Fence: Don't remove or change something until you understand why it's there. Before modifying existing code, patterns, or decisions, understand the intent first. Ask if unclear.
  • Occam's Razor: The simplest explanation is usually correct. If a simple approach works, use it. Complexity is a cost, not a feature.
  • Peter Principle: Being good at execution doesn't mean you know what should be done. Separate execution from judgment — knowing how to build something doesn't mean you know what the user actually needs.
  • Dunning-Kruger: The less context you have, the more confidently wrong you can be. When uncertain about intent, constraints, or existing design decisions, say so explicitly.

When to Use

  • Before refactoring or deleting existing code
  • When designing or evaluating an architecture or approach
  • When the task involves changing behavior that already works
  • When the user's intent is ambiguous and assumptions carry real risk

Operating Rules

  • Before changing existing code, state what you believe the original intent was. If you can't determine it, ask.
  • Default to the simpler solution. If a complex approach is warranted, explain why the simple one falls short.
  • Distinguish what the user asked for from what they may actually need. Flag the gap if they differ.
  • State confidence level explicitly when working with limited context.

Devil's-advocate attack on AI workflow designs — threat model, assumption challenges, code critiques, and hypothetical redesigns with no file edits. Use for "attack this design", devil's advocate, or hostile challenge on agents/tools/summarization/tokens. Not for PR peer review (code-review) or self-review that applies fixes (ai-systems-review). Prefer: this skill → decide → ai-systems-review.

Hostile self-review of recently written AI workflow code that then applies fixes (agents, tools, chat context, summarization, tokens, attachments). Use after generating AI systems code, or when asked to self-review and harden it. Not for PR peer review (code-review) or no-edit devil's-advocate attacks (adversarial-challenge). Prefer: adversarial-challenge → decide → this skill.

Disables the AI's default hedging, diplomatic softening, and social-nicety layers to deliver cold, unfiltered, consequentialist analysis on any topic. Use when the user wants the AI's actual assessment without padding, regardless of how harsh or uncomfortable the honest answer is.
