Playbook Pull Request

For internal contributors submitting a new Playbook. See CONTRIBUTING.md for the full submission process from branch naming through merge.

Required Files

Before submitting, confirm your Playbook folder under playbooks/<tool-slug>/ includes:

• Playbook folder at playbooks/<tool-slug>/ with a kebab-case name matching the third-party tool slug
• README.md with all 6 required sections: Use Case Overview, Architecture, Prerequisites, Code Scaffold, Deployment Guide, Known Limitations
• APPHUB.yaml present and correctly formatted (see below)
• diagrams/ folder present (e.g. with an architecture diagram)
• src/ folder present with sample code

APPHUB.yaml format

Ensure APPHUB.yaml is correctly formatted per the APPHUB schema in CONTRIBUTING.md: all required fields filled, valid values for vertical and webex_component; status = draft or review (do not set published). The Validate then Publish to Integration workflow will fail if required fields are missing or invalid.

Review Process and Turnaround

• Automated validation: When you open or update this PR, the Validate then Publish to Integration workflow runs and posts a comment with results. The PR cannot merge until all checks pass. Fix any failures and push to re-run.
• Human review: After validation passes, a reviewer performs a ~15-minute spot-check using the review criteria in CONTRIBUTING.md. You may receive change requests; push commits to this branch to address them.
• Turnaround: Reviewers aim to complete the initial spot-check within 3 business days; you will be notified of any change requests in the PR.

Reviewer: 15-Minute Spot-Check

• Does the scaffold connect to a real Webex API, SDK, or Developer Tool?
• Is the deployment guide followable by a competent developer?
• Does this duplicate an existing Playbook?

---

Self-Attestation

By submitting this PR I confirm that the deployment guide is accurate to the best of my knowledge and that Webex does not guarantee the functional accuracy of this Playbook.
