prototype-spike SKILL.md skillA
prototype-spike from stark-ai-de/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add stark-ai-de/agent-skills/prototype-spike@v0.1.0Pins v0.1.0 in mdr.lock. Pin the fingerprint instead.

Build or plan an explicitly throwaway prototype to answer a design, API, UX, performance, or integration question, then capture findings and cleanup. Use when the user asks for a spike, prototype, proof of concept, or experiment before committing to production design.
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
# Prototype Spike ## Goal Answer a specific uncertainty with a deliberately bounded prototype, then either discard it or convert only the proven idea into production work. ## When to use - The user asks for a spike, proof of concept, prototype, or throwaway experiment. - A design choice needs evidence before production implementation. - An integration, API, performance assumption, or UI interaction is uncertain. ## When not to use - The user needs production-ready implementation now. - The uncertainty can be answered by reading docs or existing code. - The prototype would require secrets, real customer data, or irreversible operations. ## Inputs to inspect - The exact question the prototype must answer. - Existing architecture, ADRs, validation commands, and domain docs. - Constraints on where prototype files may live and how they should be cleaned up. ## Workflow 1. State the hypothesis or design question. 2. Define the prototype boundary, timebox, and throwaway location. 3. Ask before adding dependencies, new services, or files outside an agreed scratch area. 4. Build the smallest experiment that answers the question. …

How to install
mdr add stark-ai-de/agent-skills/prototype-spike@sha256:0cb3dca766ba3d4cThe line at the top of this page pins the label v0.1.0, 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.
