k2
This Skill builds and troubleshoots Cloudflare K2 and K2 Streams durable logs. It covers stream creation and configuration, producing records from Workers or HTTP, setting retention and input authentication, and consuming records through subscriptions with leases and acknowledgements. Useful for decoupling event producers from consumers in event-driven architectures and for quickly resolving capacity, quota, and delivery-behavior questions.

1 组Developers bounce between several doc pages, manually cross-check input authentication, retention rules and subscription lease semantics, often copy examples that are already stale, then burn hours debugging failed deliveries.
This Skill maps each task to the matching current documentation page, supplies working produce and consume examples, and states quota and delivery behavior clearly so a stream goes from creation to consumption in one pass.
Cloudflare K2
K2 is a durable log for decoupling event producers and consumers. Start with the K2 overview, then retrieve the relevant current documentation before giving setup instructions, code, limits, availability, permissions, or API details. The docs are the source of truth over this skill. While cloudflare-docs PR #33858 remains open, use its proposed pages if the public URLs have not been published.
Documentation
| Task | Docs | Check for |
|---|---|---|
| Create a stream and try K2 | Get started | Prerequisites, setup sequence, current API examples |
| Understand streams and subscriptions | Concepts | Record model and delivery behavior |
| Configure a stream | Configuration | Inputs, authentication, CORS, retention |
| Produce from HTTP or a Worker | Produce records | Request and binding syntax, encoding, errors, retries |
| Consume through subscriptions | Consume records | Leases, acknowledgements, retries, errors |
| Size a stream or consumer | Limits | Current quotas and size limits |
Retrieve the matching pages above for each task and use their current examples. For capacity or cost questions, check current limits and any published pricing before quoting values. State when a requested pricing or availability detail is not yet published.
For SQL transformation and delivery to R2 Iceberg tables, use the basin skill. For task processing, consult Queues.
