Turn a Jam (a jam.dev screen recording with the console, network and user actions attached) into steps and an end-to-end test in the project's own runner and language, with first-class guidance for Playwright and tester-army/e2e, grounded in the current code. A Jam of a flow or demo becomes a test that guards it; a Jam of a bug becomes a failing test the fix turns green. Use when the user pastes a jam.dev link and asks for an e2e test, a regression test, a repro, or to "write a test for this".

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

# jam-to-e2e

The Jam shows what the user did and what the screen, console and network
did in return. The code shows what the labels and routes are today. The
tests assert what the product must do. One test per claim: a Jam that walks
through three screens is three tests, and a Jam of one bug is one.

A Jam is not always a bug report, so the user's request decides what the
test must do today, not the Jam:

- "Cover this flow", "write a test for this demo": the test asserts what the
  Jam shows and **passes** today. It guards the flow.
- "Regression test", "reproduce this bug", "test for this bug": the test
  asserts what should have happened and **fails** until the fix lands.
- Neither said: take the Jam's title and description as the hint, state
  which reading you took, and ask when you can.

## Pick the interface

Use the Jam Model Context Protocol (MCP) tools when they are connected.
Otherwise read [references/cli.md](references/cli.md) for the Jam CLI setup; the table
below gives the command for each read.

## 1. Read the Jam

Fetch in this order and stop when you have the steps and the expected results.

How to install

The exact contents, by fingerprint
mdr add jamdotdev/jam-plugin/jam-to-e2e@sha256:ce5a4e68be902611

The line at the top of this page pins the label git:20261022.832a0b6, 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.
