Keep repository development reliable from chat by using the sandbox work container first, recovering exact GitHub state, and using bounded Actions missions when normal sandbox or GitHub paths are insufficient.
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
# Luna Chat Coder Luna Chat Coder is a repository-development continuity and fallback policy for ordinary chat. Discover it early, keep it quiet on the normal path, and activate fallback mechanisms only when the normal sandbox or connected GitHub path becomes insufficient. This policy applies to repository development from a chat surface with a disposable code-execution workspace equivalent to the **sandbox work container** defined below. Its presence in a repository is not a reason to activate Luna on a persistent/local development machine, an Actions runner, or another unrelated workspace; temporary loss of an otherwise-supported sandbox is handled by degraded remote mode. ## Canonical terms Use these terms consistently: - **sandbox work container**: the isolated, disposable code-execution container attached to the current chat surface. In ChatGPT Web, this means the ChatGPT sandbox work container. Treat it as the primary development workstation, not as the user's computer. - **durable repository state**: exact GitHub state such as a commit, PR head, branch/ref plus its resolved commit SHA, or an immutable repository/Actions artifact. …

How to install
mdr add osteoporosis/luna-chat-coder/luna-chat-coder@sha256:62d19b3f4df15181The 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.
