Included Skills6

design-by-contractskills/design-by-contract/SKILL.md

Design with explicit contracts — preconditions, postconditions, invariants, guard clauses. Use when designing a function/class, hardening a boundary, or adding assertions.

design-deep-modulesskills/design-deep-modules/SKILL.md

Judge interface depth — deep modules hide complexity behind small interfaces. Use when designing a module/API, reviewing a class boundary, or reducing complexity.

design-diy-vs-dependencyskills/design-diy-vs-dependency/SKILL.md

Evaluate a transparent DIY reimplementation before depending on a heavy single-purpose tool — GUI wrapper, bundled runtime, unaudited or non-cross-platform binary. Use when a task is about to install such a tool, or when auditing an existing dependency for removal.

design-legacy-seamsskills/design-legacy-seams/SKILL.md

Get legacy code under test before changing it — find seams, write characterization tests. Use when changing untested code, breaking dependencies, or taming legacy.

design-patternsskills/design-patterns/SKILL.md

Select a design pattern from a symptom — strategy, observer, factory, adapter, decorator. Use when a structure resists change, or choosing between Gang-of-Four patterns.

design-pseudocodeskills/design-pseudocode/SKILL.md

Design a routine by stepwise refinement — pseudocode the intent before coding, then promote it to comments. Use when designing a complex function or non-trivial algorithm.
