A general skill for writing high-quality automated tests. Use it to design and implement stable, maintainable, and diagnosable tests for functions, modules, APIs, components, pages, and critical business workflows.
Draw clear, audience-appropriate software architecture diagrams that communicate scope, structure, interfaces, and relationships without mixing abstraction levels.
Add or refine sparse, structured, file-persisted application logs for non-trivial code changes. Use when Agent is proposing an implementation approach, writing a plan, or implementing or modifying complex business logic, critical state transitions, validation or parsing flows, boundary interactions (HTTP, DB, cache, queue, filesystem, subprocess), retries, fallbacks, async jobs, concurrency, or background tasks, because planning is the right time to decide log placement. Reuse the project's existing logging infrastructure whenever possible. Do not use for trivial edits, simple obvious CRUD, blanket "log everything" requests, or low-value noise.
Helps users design, optimize, and review the structure and content of speeches, presentations, and persuasive communication in a wide range of high-stakes scenarios. Applicable situations include, but are not limited to: startup pitches and co-founder recruiting, research presentations and thesis defenses, job talks and academic interviews, product demos and investor pitches, lab meetings and progress updates, public speaking and TEDx-style talks, conference presentations and panel remarks, oral exams and qualifying defenses, expressing viewpoints and persuading others, upward reporting and performance reviews, and internal proposals and solution walkthroughs.
Used for locating, reproducing, validating, and fixing software defects. Applicable when the user asks to "fix a bug," "locate an error," "analyze and fix an error," "reproduce an issue," "find the root cause," and similar scenarios.
Create a structured continuation handoff checkpoint for long coding or technical conversations when context is tight, the user asks to compact, another model will continue the task, or a clean resume point is needed. Preserve exact technical state, decisions, file paths, commands, blockers, failed attempts, validation status, and next steps. Do not use for generic summaries, meeting notes, or polished end-user documentation.
Trigger when the user wants to create a new FastAPI project, add new features, refactor code, or asks about architectural best practices. This skill enforces 2026 clean architecture with SQLModel, Repository Pattern, full async, and production-ready workflow.
Java Layered Architecture Design Pattern — A complete implementation guide for the classic five-layer architecture using Spring Boot + MyBatis-Plus. Suitable for bootstrapping new Java projects, refactoring existing architectures, establishing team development standards,and database migration scenarios.
