+# Requirements: GSD Quick Mode
+
+**Defined:** 2025-01-19
+**Core Value:** Same guarantees, 50-70% fewer tokens for simple tasks
+
+## v1 Requirements
+
+### Command
+
+- [ ] **CMD-01**: `/gsd:quick "description"` parses description from arguments
+- [ ] **CMD-02**: Command errors if .planning/ROADMAP.md doesn't exist
+- [ ] **CMD-03**: Command calculates next decimal phase from current phase in STATE.md
+- [ ] **CMD-04**: Command creates phase directory `.planning/phases/{decimal}-{slug}/`
+- [ ] **CMD-05**: Command inserts decimal phase entry in ROADMAP.md
+
+### Execution
+
+- [ ] **EXEC-01**: Command spawns gsd-planner (no researcher, no checker)
+- [ ] **EXEC-02**: Command spawns gsd-executor for each plan created
+- [ ] **EXEC-03**: Multiple plans execute in parallel waves (same as execute-phase)
+- [ ] **EXEC-04**: Executor commits only files it edits/creates
+
+### State
+
+- [ ] **STATE-01**: STATE.md "Last activity" updated after completion
+- [ ] **STATE-02**: STATE.md "Quick Tasks Completed" table created/updated
+- [ ] **STATE-03**: ROADMAP.md decimal phase marked complete with date
+
+### Resume
+
+- [ ] **RESUME-01**: `/gsd:resume-work` parses decimal phase numbers (3.1, 3.2)
+- [ ] **RESUME-02**: `/gsd:resume-work` finds decimal phase directories
+
+### Docs
+
+- [ ] **DOCS-01**: help.md lists `/gsd:quick` command
+- [ ] **DOCS-02**: README.md includes quick mode section
+- [ ] **DOCS-03**: GSD-STYLE.md documents quick mode patterns

+(None identified)
+
+## Out of Scope
+
+| Feature | Reason |
+|---------|--------|
+| `--plan-only` flag | MVP always executes |
+| `--after N` flag | Always uses current phase |
+| `--standalone` flag | Requires active project for state integrity |
+| Node.js helper scripts | Claude handles decimal parsing inline |
+| Git status warnings | Commits only its own files |
+| Planner modifications | Orchestrator skips agents, planner unchanged |
+| gsd-verifier | Verification skipped by design |
+| Requirements mapping | Quick tasks are ad-hoc |
+| `/gsd:squash-quick` | Future enhancement |
+
