Description

I used both Claude and OpenCode to interface with the same model GLM-4.7, and then conducted code troubleshooting. As a result, Claude identified over 120 issues, while OpenCode found only 10+. Claude demonstrated significantly stronger context awareness in code troubleshooting compared to OpenCode, which showed notably weaker context awareness. This validates my conclusion that static analysis tools cannot understand code semantics and business logic, and can only analyze based on code syntax and static rules. In contrast, AI understanding tools can analyze based on code semantics and context, thereby discovering more issues. Please enhance OpenCode's ability to analyze and understand code.

This issue might be a duplicate of or closely related to existing issues. Please check:

  • #9637: Direct comparison with Claude Code regarding auto context compression and conversation history management
  • #5993: User reports context window limitations (128K tokens cap) that prevent thorough analysis
  • #6310: Sessions become unusable due to large LSP diagnostics, limiting analysis capability
  • #3032: Context consumed ineffectively by tool calls, causing memory loss of objectives
  • #4113: Compaction issues causing frustration with memory loss and context shifts

These issues reflect similar concerns about OpenCode's analysis depth and context awareness compared to Claude Code. Feel free to ignore if your specific case is different.
