spike from varun-singhh/lfg is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Builds a throwaway prototype to answer one design question, in a scratch folder inside the run folder, then deletes it and keeps only the conclusion. Use when the user says "try a quick prototype", "would this approach work?", "spike this", "let me feel this state model", "show me a few UI options", or when a plan has an open question that a cheap working artifact would settle.
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
## Step 0: preflight 1. Run `lfg graphs ensure`. If it exits non-zero, stop and show its output (only `--allow-stale` overrides). 2. `lfg run path`. If it exits 1, run `lfg run new spike-<slug>` and use the path it prints. Call it `<run>`. ## Steps 1. **State the question** in one paragraph: what is unknown, and what result would settle it. Write it at the top of `<run>/spike-<slug>.md` before any code. 2. **Pick the shape** from the question: - *Logic / state / data shape* → one self-contained HTML file: a pure logic module in its own `<script>` (reducer, state machine or pure functions; no DOM inside it), a readable state panel re-rendered after every action, one button per action, and tabbed walkthroughs for the happy path, an awkward edge case and an illegal move. Labels in domain language. - *What should it look like* → a few clearly different variants on one throwaway page, switched by a URL param. - *Does library/API X behave like Y* → the smallest script that calls it and prints the result. If ambiguous, pick by the surrounding code (backend → logic, page → UI) and state the assumption. …

How to install
mdr add varun-singhh/lfg/spike@sha256:4a2a51a5d1481bc3The line at the top of this page pins the label git:20261015.6b3a06b, 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.
