   • skipped updates

5. antigravity.md

   • fetch failed (corrupted binary)
   • already notes pricing as TBD
   • no changes

summary:

• github copilot was underdocumented relative to its market presence
• at $10/mo copilot pro, it's the cheapest paid tier across all tools
• codex and gemini releases are recent but contain no pricing changes
• cursor/antigravity fetches were incomplete; no actionable changes

notes:

• github copilot's billing experience is paused for redesign (noted in may 2026 pricing page)
• pricing changes may follow when billing redesign completes
• recommend re-verify github copilot pricing after redesign completes
