"Safely remove a feature flag from code while preserving production behavior. Use when the user wants to remove a flag from code, delete flag references, or create a PR that hardcodes the winning variation after a rollout is complete."
abstract-domain-explorer
by ArabelaTso
Applies abstract interpretation using different abstract domains (intervals, octagons, polyhedra, sign, congruence) to statically analyze program variables and infer invariants, value ranges, and relationships. Use when analyzing program properties, inferring loop invariants, detecting potential errors, or understanding variable relationships through static analysis.

Scan a codebase for deepening opportunities, present them as a visual HTML report, then grill through whichever one you pick. Covers Stacks engineering workflows.
tdd
by ryoppippi
Guides execute-inspect-adjust development and t-wada Red-Green-Refactor TDD. Use for exploratory implementation or when stable behaviour needs an executable test-first contract.
code-smell-detector
by ArabelaTso
Identify and report code smells indicating poor design or maintainability issues in Python code, including duplicate code, magic numbers, hardcoded values, God classes, feature envy, inappropriate intimacy, data clumps, primitive obsession, and long parameter lists. Use when conducting code quality audits, preparing for refactoring, improving codebase maintainability, or performing design reviews. Produces markdown reports with severity ratings, locations, descriptions, and specific refactoring recommendations with before/after examples. Triggers when users ask to find code smells, identify design issues, suggest refactorings, improve code quality, or detect maintainability problems.

dynamic-lot-sizing
by kishorkukreja
When the user wants to solve lot-sizing problems with time-varying costs or demand, handle non-stationary inventory systems, or optimize replenishment with changing parameters over time. Also use when the user mentions "time-varying lot sizing," "finite horizon lot sizing," "dynamic EOQ," "price changes over time," "seasonal lot sizing," "Wagner-Whitin with time-varying costs," or "rolling horizon planning." For stationary systems, see economic-order-quantity or lot-sizing-problems. For stochastic demand, see stochastic-inventory-models.
