Review code formatting and documentation using 74-item checklist from Code Complete. Two modes: CHECKER executes checklists with evidence tables, APPLIER guides layout decisions and commenting strategy. Use when code has inconsistent formatting, poor visual structure, unclear comments, or readability issues. Triggers on: review formatting, check layout, code style review, commenting style, make readable, multiple statements per line, endline layout, comments repeat code.
Verify construction prerequisites using 66-item checklists across requirements, architecture, and coding conventions. Output status tables (VIOLATION/WARNING/PASS) in CHECKER mode or prerequisite allocation recommendations in APPLIER mode. Use when unsure if project is ready to code, requirements feel incomplete, architecture unclear, no coding conventions defined, or noticing urge to skip planning. Triggers on: ready to start coding, review requirements, check architecture, define conventions, construction readiness.
Review control flow quality using 87-item checklist. Use when code has deep nesting (3+ levels), complex conditionals, loop design questions, high cyclomatic complexity (McCabe >10), or callback hell. Symptoms: arrow-shaped code, repeated conditions, confusing loop exits, lengthy if-else chains. Provide refactoring patterns (guard clauses, named booleans, table-driven methods) and modern guidance (async/await, pattern matching, functional pipelines). Produce verified code with pass/fail assessment.
Audit and fix data organization: variable declarations, data types, magic numbers, naming conventions, and global data. Three modes: CHECKER (92-item checklist -> status table), APPLIER (type selection and naming guidance), TRANSFORMER (fix violations). Cover modern types: concurrent/shared state, nullable/optional, temporal/timezone, security-sensitive. Use when reviewing code for data organization issues, choosing data types, or fixing magic numbers. Triggers on: review variables, data types, magic numbers, naming, global data, check types, fix floats, constants.
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.
Review error handling, input validation, and exception patterns using 24-item checklist. 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. Produce status table with VIOLATION/WARNING/PASS per item, or barricade/error-handling design recommendations.
Enforce developer discipline under pressure by detecting rationalization patterns and providing counter-arguments. Use when stuck debugging, considering skipping reviews, feeling overconfident about technical decisions, resisting unfamiliar techniques, or treating methodology as dogma. Triggers on: just compile and see, ignoring warnings, 90% complete for weeks, gonzo programming, I don't need to test this, unrealistic estimates.
