minimal-reproduction SKILL.md skillA
minimal-reproduction from yeaight7/agent-powerups is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add yeaight7/agent-powerups/minimal-reproduction@git:20260606.a199b74Pins git:20260606.a199b74 in mdr.lock. Pin the fingerprint instead.

Use when a bug must be isolated from a large application into a standalone, runnable script or single test case.
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
## Purpose
You cannot reliably fix what you cannot reliably reproduce in isolation. Apply the subtraction method until a single file deterministically triggers the exact reported error.
## When to Use
- A bug is tangled in app/UI/network layers and hard to debug in place
- A failure must be handed to another engineer, team, or upstream project
- Before bisecting or stress-testing, to get a fast deterministic signal
## Inputs
- The failing code path and the error it produces
- Sample data that triggers the failure, if any
## Workflow — the Subtraction Method
1. **Start with the failure.** Take the code path that fails.
2. **Remove the UI/Network.** If the bug is reported via a web request, write a script that calls the internal controller directly.
3. **Mock dependencies.** If the bug doesn't require the database, mock it. If it doesn't require the third-party API, mock it. Template:
```js
// repro.js — minimal harness, no framework
const { failingFunction } = require("./src/module");
const fakeDb = { query: async () => [{ id: 1, value: null }] }; // smallest stub that triggers it
failingFunction(fakeDb, { payloadKey: "trigger-value" })
…Read the whole file at its exact version.
How to install
mdr add yeaight7/agent-powerups/minimal-reproduction@sha256:d7bd32e87c12f411The line at the top of this page pins the label git:20260606.a199b74, 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.
