Note

Clarifies the distinction between vCluster sleep mode with and without a platform agent, adds Istio gateway support for activity detection.

• Sleep mode configuration (sleep-mode.mdx)
  • Added detailed comparison of sleep mode behavior with vs without platform agent
  • Added comparison table showing key differences (control plane state, resource savings, auto-deletion)
  • Improved "Connect to the platform" section explaining agent takeover of sleep mode
  • Added control plane behavior tips for deployment configuration
  • Minor formatting fixes (removed backticks from inline code in prose)
• Sleep and wakeup (sleep-wakeup.mdx)
  • Added new "Manual vs automatic sleep mode" section to clarify the two approaches
  • Added "What happens during manual sleep" and "Differences from automatic sleep mode" sections
  • Added "When to use manual vs automatic sleep mode" guidance section
  • Grammar fix: "needs" → "need" for subject-verb agreement
• Activity detection partial (activity-detection.mdx)
  • Added Istio Gateways with Virtual Services to supported activity detection methods
  • Added explanation of how VirtualServices are modified during sleep/wake

Findings

Issues Found

1. vcluster/configure/vcluster-yaml/sleep-mode.mdx:210 & 217 - Duplicated paragraph:
   The sentence "This setup allows the virtual cluster to reduce resource usage while still being able to monitor activity and trigger wake-up actions when needed." appears twice - once at line 210 and again at line 217. The first occurrence should be removed as it appears before the admonition and is duplicated immediately after it.

2. vcluster/configure/vcluster-yaml/sleep-mode.mdx:23 - Link uses URL path instead of relative file path:
   /vcluster/configure/vcluster-yaml/sleep-mode should use relative path with .mdx extension per style guide. However, since this is a self-reference within the same file (the link points to the file itself), this could be simplified or removed.

3. vcluster/manage/sleep-wakeup.mdx:23 - Link uses URL path instead of relative file path:
   /vcluster/configure/vcluster-yaml/sleep-mode should use a relative file path like ../configure/vcluster-yaml/sleep-mode.mdx

4. vcluster/manage/sleep-wakeup.mdx:72, 119 - Same URL path link issue as above.

5. vcluster/configure/vcluster-yaml/sleep-mode.mdx:166 - Grammatically awkward sentence:
   "In version 0.24.x, the autoDelete configuration is still under external.platform and is set to move under sleepMode in a later release. external.platform to be moved under sleepMode in a future release."
   The second sentence is incomplete/fragmented.

Style Guide Compliance Verified

• ✅ Sentence case used correctly in headings
• ✅ Present tense and active voice used throughout
• ✅ No usage of "easy", "simple", "obvious"
• ✅ vCluster trademark used correctly (never pluralized as "vClusters")
• ✅ YAML code blocks have correct indentation
• ✅ No admonitions inside JSX components like <Step>
• ✅ External links to GitHub and Istio are properly formatted with markdown syntax
