prototype SKILL.md skillA
prototype from firzus/agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add firzus/agent-skills/prototype@git:20261102.3c649dePins git:20261102.3c649de in mdr.lock. Pin the fingerprint instead.

Answer a design or feasibility question with the smallest observable experiment, such as comparing interface variants, exercising domain rules, or measuring a technical limit. Use when a decision needs observed behavior rather than more discussion or source research; not for building the settled feature.
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 a decision Build the smallest experiment that answers one question in a representative environment. A prototype produces evidence for a decision, not a production feature, and its approval says nothing about production reliability. ## 1. Bound the question State the question, the decision it informs, the scenarios to observe, and the evidence that will end the experiment. Separate what can be measured, which you settle yourself, from what needs the user's judgment, such as which variant feels clearer. If source evidence alone would answer it, research instead; if the behavior is already settled, show the evidence and stop. ## 2. Build it where it counts Reuse the real product, components, and data shape as far as the question needs: isolated logic cannot show real rendering, device interaction, or performance. Work on a dedicated branch, `prototype/<subject>`, without disturbing the user's checkout or uncommitted work. Run it on a copy of the data or on fixtures, with external services simulated, and label every simulated dependency; an experiment that needs a real external effect asks the user first. | Question about | Build and observe | | --- | --- | …

How to install
mdr add firzus/agent-skills/prototype@sha256:c9736688e831c3b3The line at the top of this page pins the label git:20261102.3c649de, 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.
