Spike - a time-boxed experiment resolving one unknown before you bet on it, risk-first, with a validated | invalidated | inconclusive verdict.
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
<objective>
Answer one unknown with evidence before a plan commits to it - "will this
approach work", "is this library fast enough", "does this API do what we need".
The discipline is what makes it useful: falsifiable criteria written BEFORE the
experiment, the riskiest assumption tested first so a dead end dies fast, and an
honest verdict. The code is throwaway; the SPIKE.md verdict is the deliverable.
</objective>
<execution_context>
@${CLAUDE_PLUGIN_ROOT}/cadence-core/workflows/spike.md
</execution_context>
<process>
Run the spike workflow end-to-end. Write the Given/When/Then criteria before
building anything, order them risk-first, and stop the moment a risk-first
criterion invalidates the approach. Never soften an invalidated result into
"inconclusive" to save the idea - a spike that kills a bad approach is a success.

How to install
mdr add crenshawdev/cadence/cad-spike@sha256:762eb24d25ae4c01The line at the top of this page pins the label git:20261029.0ae5ff0, 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.
