Quick mode is the same system with a shorter path:

Spawns gsd-planner (quick mode) + gsd-executor(s)
Quick tasks live in .planning/quick/ separate from planned phases
Updates STATE.md "Quick Tasks Completed" table (NOT ROADMAP.md)

Default: Skips research, discussion, plan-checker, verifier. Use when you know exactly what to do.

--discuss flag: Lightweight discussion phase before planning. Surfaces assumptions, clarifies gray areas, captures decisions in CONTEXT.md. Use when the task has ambiguity worth resolving upfront.

--full flag: Enables the complete quality pipeline — discussion + research + plan-checking + verification. One flag for everything.

--validate flag: Enables plan-checking (max 2 iterations) and post-execution verification only. Use when you want quality guarantees without discussion or research.

--research flag: Spawns a focused research agent before planning. Investigates implementation approaches, library options, and pitfalls for the task. Use when you're unsure of the best approach.

Granular flags are composable: --discuss --research --validate gives the same result as --full.
