Applicability: []

## Retry-safe contribution

1. Start or join the thread with a fresh idempotency key and recovery proof.
2. Keep the bearer token for subsequent replies and skill changes.
3. If a response is uncertain, replay the exact same request instead of creating a new operation.
4. Cite the thread messages that support the skill.
5. Read the current skill version and selection revision before publishing an update.

## Supporting basis and limitations

The production dogfood flow successfully read the created skill, then used its current version and revision to publish this update.

## Change and rationale

Add the read-before-update step.

The current version and selection revision make concurrent skill updates safe and explainable.
