Use when Claude writes, modifies or reviews code (file formats, network requests, images/assets, loops, caching, pagination, dependencies, framework or AI model choice), when the user asks for a sobriety audit ("eco-design audit", "check this code for sobriety", "--eco-check", "RGESN", "GR491", "eco-design", "green IT", "audit éco-conception", "vérifie la sobriété de ce code", "écoconception"), or when invoked via /green-claude to walk through the rule checklist.

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

# Green Claude

**What this skill is for.** Deliver code that consumes as little as possible:
the fewest tokens during the session, the least CPU time and memory at runtime,
the fewest bytes over the network, the least storage, and therefore the least
energy. That is what digital sobriety means in practice, and it is the reason
every rule below exists. A rule that does not eventually reduce a resource
someone pays for is not worth the context it takes.

The consumption comes in two waves, and the second is the larger one. During the
session, the context you transmit and the output you produce are processed by a
model, which costs computation and the energy behind it. After the session, the
code you leave behind runs on every user's machine, on every request, for years.
Both matter; only one of them stops when the conversation does.

Four rule sets: `rules/ecoconception.json` (107 rules, RGESN 2024 / GR491 /
Green Software Foundation / W3C WSG) while you write or modify code,
`rules/langages/*.json` (127 rules across 24 languages and frameworks) for the language you're
working in, and, during the conversation itself, `rules/usage.json` (13

How to install

The exact contents, by fingerprint
mdr add institut-du-numerique-responsable/green-claude/green-claude@sha256:6af0e01d17602176

The line at the top of this page pins the label v1.5.0, 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.
