<arguments>$ARGUMENTS</arguments>

The text inside `<arguments>` is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.

<objective> Execute all plans in a phase using wave-based parallel execution.

Orchestrator stays lean: discover plans, analyze dependencies, group into waves, spawn subagents, collect results. Each subagent loads the full execute-plan context and handles its own plan.

Optional wave filter:

• `--wave N` executes only Wave `N` for pacing, quota management, or staged rollout
• phase verification/completion still only happens when no incomplete plans remain after the selected wave finishes

Flag handling rule:

• The optional flags documented below are available behaviors, not implied active behaviors
• A flag is active only when its literal token appears in the `<arguments>` block
• If a documented flag is absent from the `<arguments>` block, treat it as inactive

Context budget: ~15% orchestrator, 100% fresh per subagent. </objective>

<runtime_note> **Copilot (VS Code):** Use `vscode_askquestions` wherever this workflow calls `AskUserQuestion`. They are equivalent — `vscode_askquestions` is the VS Code Copilot implementation of the same interactive question API. </runtime_note>

<context> Phase: the `<arguments>` block

**Available optional flags (documentation only — not automatically active):**

• `--wave N` — Execute only Wave `N` in the phase. Use when you want to pace execution or stay inside usage limits.
• `--gaps-only` — Execute only gap closure plans (plans with `gap_closure: true` in frontmatter). Use after verify-work creates fix plans.
• `--interactive` — Execute plans sequentially inline (no subagents) with user checkpoints between tasks. Lower token usage, pair-programming style. Best for small phases, bug fixes, and verification gaps.

**Active flags must be derived from the `<arguments>` block:**

• `--wave N` is active only if the literal `--wave` token is present in the `<arguments>` block
• `--gaps-only` is active only if the literal `--gaps-only` token is present in the `<arguments>` block
• `--interactive` is active only if the literal `--interactive` token is present in the `<arguments>` block
• If none of these tokens appear, run the standard full-phase execution flow with no flag-specific filtering
• Do not infer that a flag is active just because it is documented in this prompt

Context files are resolved inside the workflow via `gsd-tools query init.execute-phase` and per-subagent `<required_reading>` blocks. </context>

<process> Execute end-to-end. Preserve all workflow gates (wave execution, checkpoint handling, verification, state updates, routing). </process>
