Reviews an API, SDK or CLI from the consuming developer's side: time to first success, types, errors, quickstart. Use for 'DevEx review' or 'is this API easy to use?'.

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

# Plan DevEx Review (Developer Experience & Ergonomics)

## Overview

When building developer tools, public APIs, SDKs, or shared internal libraries, developer experience (DevEx) dictates adoption. If an API is cumbersome, confusing, or poorly typed, developers abandon it.

`plan-devex-review` reviews code interfaces from the consumer developer's perspective, optimizing for minimal time-to-first-hello-world and intuitive ergonomics.

## When to Use

- When designing public or internal REST/GraphQL APIs, MCP tools, or SDKs.
- When creating CLI tools or automation scripts.
- When drafting developer documentation and code examples.

## Key Principles of Elite DevEx

1. **Zero-Config Defaults, Infinite Customizability**:
   - Simple tasks must take 3 lines of code; complex tasks should remain possible.
2. **Predictable Naming & Typing**:
   - Strict TypeScript/Pydantic types with informative IDE autocomplete and inline docstrings.
3. **Actionable Error Messages**:
   - Never return generic `Error: Invalid argument`.
   - Always return: `Error: Missing 'apiKey'. Set the ANTHROPIC_API_KEY environment variable or pass { apiKey: '...' } in config.`
4. **Copy-Paste Ready Examples**:

How to install

The exact contents, by fingerprint

mdr add gastonchevarria/god-mode/plan-devex-review@sha256:5f11fec7bd6742bb

The line at the top of this page pins the label git:20261014.522e28a, 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.
