Throwaway HTML mockups: 2-3 design variants to compare.
Breaks work into ordered tasks. Use when you have a spec or clear requirements and need to break work into implementable tasks. Use when a task feels too large to start, when you need to estimate scope, or when parallel work is possible.
Execute implementation plans by dispatching fresh subagents per task with two-stage review. Use when executing a multi-task implementation plan, when context is getting too long for quality output, or when you want maximum isolation between tasks.
Core tGD rules that MUST be followed at all times — the Verification Iron Law, per-phase tone, the Command Closing Report, and human sign-off. Load this at the start of every tGD session (the session-start meta-skill tgd-router points here) and whenever a command references it. Do not skip, do not rationalize exceptions.
Discovers and invokes agent skills. Use when starting a session or when you need to discover which skill applies to the current task. This is the meta-skill that governs how all other skills are discovered and invoked.
Creates specs before coding. Use when starting a new project, feature, or significant change and no specification exists yet. Use when requirements are unclear, ambiguous, or only exist as a vague idea.
Conducts multi-axis code review. Use before merging any change. Use when reviewing code written by yourself, another agent, or a human. Use when you need to assess code quality across multiple dimensions before it enters the main branch.
Guides systematic root-cause debugging. Use when tests fail, builds break, behavior doesn't match expectations, or you encounter any unexpected error. Use when you need a systematic approach to finding and fixing the root cause rather than guessing.
