STOP - Refactoring Rules
- Fix first, then refactor - Never simultaneously (separate commits)
- Small changes need MORE rigor, not less - 1-line changes have HIGHEST error rate
- >50% of changes fail first attempt - Review and test even "trivial" changes
Quick Reference
| Rule | Value | Source |
|---|---|---|
| Small change error rate | Peaks at 1-5 lines | Weinberg 1983 |
| First attempt success rate | <50% for any change | Yourdon 1986b |
| Review effect on 1-line changes | 55% -> 2% error rate | Freedman and Weinberg 1982 |
| Big refactoring | "Recipe for disaster" | Kent Beck |

cc-defensive-programming
Use when auditing defensive code, designing barricades, choosing assertion vs error handling, or deciding correctness vs robustness strategy. Triggers on: empty catch blocks, missing input validation, assertions with side effects, wrong exception abstraction level, garbage in garbage out mentality, deadline pressure to skip validation, trusted source rationalization.
29building
Execute whiteboard plans through gated phases with subagent dispatch. Require feature branch. Each phase goes through PRE-GATE (discovery + pseudocode) -> IMPLEMENT -> POST-GATE (reviewer) -> CHECKPOINT. Produce per-phase commits, execution log, and working code with tests. Use after /code-foundations:whiteboarding to implement saved plans. Triggers on: build it, execute plan, implement the whiteboard, run the plan.
1cc-debugging
Guide systematic debugging using scientific method: STABILIZE -> HYPOTHESIZE -> EXPERIMENT -> FIX -> TEST -> SEARCH. Two modes: CHECKER audits debugging approach (outputs status table with violations/warnings), APPLIER guides when stuck (outputs stabilization strategy, hypothesis formation, fix verification). Use when encountering ANY bug, error, test failure, crash, wrong output, flaky behavior, race condition, regression, timeout, hang, or code behavior differing from intent. Triggers on: debug, fix, broken, failing, investigate, figure out why, not working, it doesn't work, something's wrong.
1whiteboarding
Brainstorm and plan features through codebase search, technology research, and 2-3 approach comparison before producing implementation-ready plans. Use when starting features, designing solutions, or planning complex work. Triggers on: whiteboard, let's plan, brainstorm, design this, figure out how to build. Save plans to docs/plans/ for execution via /code-foundations:building.
1prototype
Validate technical feasibility with minimum code before full implementation. Prove ONE atomic question ('Can I X?') through 6-phase workflow: SCOPE, CONTEXT, MINIMUM, EXECUTE, VERIFY, CAPTURE. Use when facing technical uncertainty, unsure if something is possible, or need proof before planning. Triggers on: prototype, POC, prove this works, spike, demo this, can I do X, is it possible, feasibility check. Produce prototype log in docs/prototypes/ with YES/NO/PARTIAL verdict and chain to whiteboarding.
1setup-ast
Configure tree-sitter CLI and language grammars for AST-powered code review. Use when AST extraction fails, tree-sitter not found, grammars missing, or setting up new machine. Triggers on: setup tree-sitter, install grammars, AST not working, tree-sitter not found, setup ast.
