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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- 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` …

How to install
mdr add product-on-purpose/pm-skills/develop-spike-summary@sha256:1ea0e82f08c02924The line at the top of this page pins the label v2.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
