Compare two .env files by key, not by line: added / removed / changed / commented-out, with secret redaction that still reports whether the secret changed.
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 this skill does

中文：按键名（而非行）对比两个 .env 文件：新增/缺失/变更/被注释，密钥可脱敏且仍报告是否变化
## When to use
- Human or agent needs **Env Diff** (`dev/env-diff`).
- Tier: `core` · side-effect: `pure` · meter: `forge.dev.env_diff`.
## How to invoke
```http
POST /api/v1/tools/invoke/dev/env-diff
Content-Type: application/json
{"input":{"text":"example"}}
```
MCP name: `dev__env-diff`
## Engine
- **nebutra-dotenv-parity** 1.0.0
- Upstream: dotenv file grammar (motdotla/dotenv parse rules) + IEEE Std 1003.1-2017 §8.1
## Composition (next)
Chain these after a successful run when the job continues:
- (none seeded yet)
## Limits
- Prefer pure/deterministic path; do not invent model calls.
- Respect input schema validation errors from invoke.Read the whole file at its exact version.
How to install
mdr add nebutra/nebutra-sailor/env-diff@sha256:d701a60154b3900fThe 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.
