develop-spike-summary
Documents the results of a completed technical or design spike, capturing the original question, approach, evidence-backed findings, and a clear proceed-or-not recommendation so the team does not re-litigate the exploration. Use once a time-boxed investigation has concluded. For the architecture decision the spike informs, use develop-adr instead; for research-based exploration, use discover-interview-synthesis.
npx skills add product-on-purpose/pm-skills --skill develop-spike-summary --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
<!-- PM-Skills | https://github.com/product-on-purpose/pm-skills | Apache 2.0 --> # Spike Summary A spike summary documents the results of a time-boxed exploration - a focused investigation to reduce uncertainty before committing to implementation. Spikes answer specific questions like "Can we integrate with this API?" or "Is this technology viable for our use case?" The summary captures findings so the team can make informed decisions without the spike participants needing to repeat explanations. ## When to Use - After completing a time-boxed technical exploration - When evaluating technology choices or vendor options - After proof-of-concept work that needs to inform team decisions - When investigating feasibility of a proposed solution - Before committing engineering resources to a new approach ## When NOT to Use - You are recording the resulting architecture decision itself -> use `develop-adr`; the spike informs, the ADR decides - The exploration was user research, not technical or design feasibility -> use `discover-interview-synthesis` - You want to propose the solution the spike pointed to -> use `develop-solution-brief` - The spike has not happened yet: this skill document

What does the develop-spike-summary skill do?
Documents the results of a completed technical or design spike, capturing the original question, approach, evidence-backed findings, and a clear proceed-or-not recommendation so the team does not re-litigate the exploration. Use once a time-boxed investigation has concluded. For the architecture decision the spike informs, use develop-adr instead; for research-based exploration, use discover-interview-synthesis.
How do I install it?
Run `npx skills add product-on-purpose/pm-skills --skill develop-spike-summary --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From product-on-purpose/pm-skills, a repository with 518 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
