Use when trading workers consume order or tick events from a Kafka consumer group and a rebalance can move a partition mid-flight. Fences revoked partitions, drains in-flight work, and commits the next offset rather than the last processed one.
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
## When to Use Use this skill when worker nodes in an event-driven trading architecture consume from a Kafka (or Redpanda) **consumer group** and the events drive side effects that must not happen twice — order submissions, position updates, fills applied to a book. A rebalance moves partition ownership between members. Between the moment a worker stops owning a partition and the moment it notices, two failure modes are live: - **Zombie execution** — the worker keeps submitting orders for a partition another member already owns. - **Duplicate execution** — the new owner replays events the old owner processed but never committed. Both are ordinary consequences of at-least-once delivery, and both are decided by what happens inside `on_partitions_revoked` / `on_partitions_assigned` / `on_partitions_lost`. `scripts/rebalance_guard.py` is the state machine that makes that ordering explicit. ## When NOT to Use - **As a Kafka client.** The guard performs no network I/O. It calls back into *your* `commit_fn` and `flush_fn`; you still wire it to `consumer.commit(asynchronous=False)` and your executor. Constructed without a `commit_fn`, it fences and drains but …

How to install
mdr add himanshuj16/algo-trading-skills/consumer-group-rebalance-safety@sha256:9b25d3b3891ff6bbThe line at the top of this page pins the label v2.0.0, 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.
