— the description by Cloudflare

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The K2 skill provides guidance on implementing and managing Cloudflare K2 durable logs. It assists users in setting up streams, configuring inputs and retention policies, producing records from Workers or HTTP, and consuming data via subscriptions. The skill relies on official documentation as the source of truth to ensure accurate API usage, limit awareness, and configuration best practices.

What it does

  • Guides users through the initial setup and creation of K2 streams.
  • Provides instructions for producing records from Cloudflare Workers or HTTP endpoints.
  • Explains how to configure stream settings including retention, authentication, and CORS.
  • Assists in implementing consumer subscriptions with lease and acknowledgement logic.
  • Helps troubleshoot stream performance and configuration issues based on platform limits.
  • Facilitates feedback submission to improve the skill's accuracy and content.

When to use it

  • When you need to decouple event producers and consumers using durable logs.
  • When setting up a new K2 stream and requiring configuration guidance.
  • When you encounter errors while producing or consuming records from a stream.
  • When you need to verify current platform quotas, limits, or API syntax for K2.

Advantages

  • Ensures adherence to the latest official documentation and API standards.
  • Provides structured guidance for complex streaming workflows.
  • Helps maintain consistency in stream configuration and resource management.
  • Includes a clear process for reporting and fixing outdated or incorrect information.

Usage examples

“How do I start a new K2 stream?”
The agent will retrieve the latest 'Get started' documentation and provide the necessary steps, prerequisites, and API examples to initialize your stream.
“What are the limits for my K2 stream?”
The agent will reference the platform limits documentation to provide current quotas and sizing constraints for your specific stream configuration.

Documentation by Cloudflare

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.

Skill feedback

If the user reports that this skill gave incorrect or outdated guidance, or is missing information, read references/skill-feedback.md.

Skill feedback

GitHub issues are public: anyone can read an issue once it is posted. Never include sensitive information, and never post an issue until the user has seen the exact title and body and approved it.

Use this when the user reports that the k2 skill gave incorrect or outdated guidance, is missing information, or could be improved. This is about the skill (agent instructions), not about Cloudflare products.

What not to include

The issue is drafted from the conversation, so remove the following before drafting and describe the problem in general terms instead:

  • Credentials, API tokens, secrets, and passwords

  • Account IDs, zone IDs, and other resource identifiers

  • Customer or personal data, such as names, email addresses, and IP addresses

  • Internal hostnames and URLs

  • Private code, configuration, and logs

Steps

  1. Ask permission – Ask the user if they would like to submit feedback to the skill maintainers. If they decline, move on.

  2. Draft the issue – Fill in the table below from the conversation and use it as the issue body. Always identify which specific file and section caused the problem. Leave out everything listed in What not to include.

  3. Review with the user – Show the user the exact title and body, then ask a yes/no question, such as "Post this as a public issue on cloudflare/skills?" Submit only after the user answers yes. If they ask for changes, apply them and ask again. If they answer no, do not post. Agreeing to send feedback in step 1 is not approval of the text.

  4. Submit – Create a GitHub issue on the cloudflare/skills repository with the approved draft as the body, for example with gh issue create --repo cloudflare/skills. The title must follow this format: skill-feedback: k2: <summary of the problem>.

  5. Share the result – Share the issue URL with the user after submission. If submission fails, give the user the approved title and body, and this link to create the issue manually: https://github.com/cloudflare/skills/issues/new
