sharp-edges
Identifies error-prone APIs, dangerous configurations, and footgun designs that enable security mistakes. Use when reviewing API designs, configuration schemas, cryptographic library ergonomics, or evaluating whether code follows 'secure by default' and 'pit of success' principles. Triggers: footgun, misuse-resistant, secure defaults, API usability, dangerous configuration.
simplify
Audits a codebase for unnecessary complexity -- premature abstractions, deep nesting, inconsistent patterns, and indirection that hurts readability. Use when asked to simplify code, audit complexity, reduce cognitive load, or review maintainability. Triggers: simplify, complexity audit, too complex, hard to read, maintainability review.
summarize-work
Summarizes session work for commit messages or branch reviews. Queries the OpenCode server API to find and read sessions, extract major changes, bug fixes, challenges requiring multiple iterations, and code review fixes. Load before committing or when preparing to document completed work.
