How to use
- Copy the installation command and review the source package before installing it in your own agent environment.
- Check the source document for required tools, credentials and supported hosts.
- Describe your input and desired deliverable; review the output against the source material.

<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> Spike an idea through experiential exploration — build focused experiments to feel the pieces of a future app, validate feasibility, and produce verified knowledge for the real build. Spikes live in .planning/spikes/ and integrate with GSD commit patterns, state tracking, and handoff workflows.
Two modes:
- Idea mode (default) — describe an idea to spike
- Frontier mode (no argument or "frontier") — analyzes existing spike landscape and proposes integration and frontier spikes
Does not require prior new-project setup — auto-creates .planning/spikes/ if needed. </objective>

<runtimenote> **Copilot (VS Code):** Use `vscodeaskquestions wherever this workflow calls AskUserQuestion`. </runtime_note>
<context> Idea: the <arguments> block
Available flags:
--quick— Skip decomposition/alignment, jump straight to building. Use when you already know what to spike.--text— Use plain-text numbered lists instead of AskUserQuestion (for non-Claude runtimes).--wrap-up— Package spike findings into a persistent project skill for future build conversations. Runs the spike-wrap-up workflow.
</context>
<process> Parse the first token of the <arguments> block:
- If it is
--wrap-up: strip the flag, execute the spike-wrap-up workflow - Otherwise: pass all of the
<arguments>block as the idea to the spike workflow end-to-end.
Preserve all workflow gates (prior spike check, decomposition, research, risk ordering, observability assessment, verification, MANIFEST updates, commit patterns). </process>
