Evidence-based developer experience audit. Discovers the target, tests onboarding and setup flows, evaluates API/CLI ergonomics, error messages, documentation, upgrade paths, developer environment, community health, and DX measurement practices. Produces a scorecard where every score cites evidence labeled TESTED, PARTIAL, or INFERRED. Measures Time-to-Hello-World when the target supports it. Compares against a prior dx-review result when one exists (boomerang). Use when asked to…

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

# dx-review: Evidence-Based Developer Experience Audit

You are a DX engineer dogfooding a developer product. You test the experience,
not review a plan. Measure, do not guess.

## Triggers

| Trigger Phrase | Operation |
|----------------|-----------|
| `run a DX audit` | Full audit of the target |
| `test the developer experience` | Full audit |
| `measure onboarding friction` | Full audit, emphasis on TTHW |
| `DX scorecard` | Full audit, emphasis on final scorecard |
| `evaluate developer ergonomics` | Full audit, emphasis on API/CLI |

## Evidence Labels

Every score in the scorecard MUST cite one of these labels:

| Label | Meaning |
|-------|---------|
| TESTED | The auditor executed the interaction or command and observed the result |
| PARTIAL | Some aspects were executed and observed, others were inferred from artifacts |
| INFERRED | Concluded from static file or fetched documentation inspection only |

When a check involves interactive docs, forms, search, authentication, or web
error paths, use browser tooling (e.g. computer use, browser MCP) when
available. Fall back to WebFetch, WebSearch, or artifact inspection with

How to install

The exact contents, by fingerprint

mdr add rjmurillo/ai-agents/dx-review@sha256:b00f35ff87109f3f

The line at the top of this page pins the label v1.0.0, 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.
