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.
Source documentation, not instructions for this website. Review permissions before running any commands.
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.
develop-adr; the spike informs, the ADR decidesdiscover-interview-synthesisdevelop-solution-briefWhen asked to document a spike, follow these steps:
State the Question Clearly Articulate the specific question the spike was designed to answer. Good spike questions are focused and answerable with the time-box available. If the question evolved during the spike, document both the original and final versions.
Define the Time-Box Document the time allocated (e.g., 3 days) and actual time spent. If the spike exceeded its time-box, explain why and note any remaining work.
Describe the Approach Explain what was tried, in what order, and why. This helps future readers understand the methodology and whether alternative approaches were considered.
Present Findings with Evidence Document what was learned, supported by concrete evidence - code samples, performance benchmarks, screenshots, or API responses. Distinguish between verified findings and hypotheses that need more testing.
Make a Clear Recommendation Answer the original question directly: proceed, do not proceed, or proceed with conditions. Avoid hedging - the team needs actionable guidance.
Document Artifacts Link to any code, prototypes, diagrams, or documentation created during the spike. These artifacts often have ongoing value beyond the summary.
Capture Open Questions Note what the spike didn't answer and what additional investigation might be needed.
Use the template in references/TEMPLATE.md to structure the output. A complete spike summary fills every template section: Overview; Background; Approach; Findings; Recommendation; Artifacts; Open Questions; and Follow-up Items.
Before finalizing, verify:

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 documents results; time-box and run the exploration first ## Instructions When asked to document a spike, follow these steps: 1. **State the Question Clearly** Articulate the specific question the spike was designed to answer. Good spike questions are focused and answerable with the time-box available. If the question evolved during the spike, document both the original and final versions. 2. **Define the Time-Box** Document the time allocated (e.g., 3 days) and actual time spent. If the spike exceeded its time-box, explain why and note any remaining work. 3. **Describe the Approach** Explain what was tried, in what order, and why. This helps future readers understand the methodology and whether alternative approaches were considered. 4. **Present Findings with Evidence** Document what was learned, supported by concrete evidence - code samples, performance benchmarks, screenshots, or API responses. Distinguish between verified findings and hypotheses that need more testing. 5. **Make a Clear Recommendation** Answer the original question directly: proceed, do not proceed, or proceed with conditions. Avoid hedging - the team needs actionable guidance. 6. **Document Artifacts** Link to any code, prototypes, diagrams, or documentation created during the spike. These artifacts often have ongoing value beyond the summary. 7. **Capture Open Questions** Note what the spike didn't answer and what additional investigation might be needed. ## Output Format Use the template in `references/TEMPLATE.md` to structure the output. A complete spike summary fills every template section: Overview; Background; Approach; Findings; Recommendation; Artifacts; Open Questions; and Follow-up Items. ## Quality Checklist Before finalizing, verify: - [ ] Original question is clearly stated - [ ] Time-box is documented (allocated vs. actual) - [ ] Findings are supported by evidence, not just opinions - [ ] Recommendation directly answers the question - [ ] Artifacts (code, diagrams) are linked or attached - [ ] Open questions identify remaining unknowns ## Examples See `references/EXAMPLE.md` for a completed example.
