This issue might be a duplicate of existing issues. Please check:

• [FEATURE]: Support standard skills location at .agents/skills/ #10986: [FEATURE]: Support standard skills location at .agents/skills/ - This is the feature request to support the standard skills location that your issue is concerned about
• OPENCODE_DISABLE_CLAUDE_CODE=1 also disable .agents/skills added in v1.1.50 #12432: OPENCODE_DISABLE_CLAUDE_CODE=1 also disable .agents/skills added in v1.1.50 - Related to .agents/skills functionality and bugs
• [FEATURE]: add environment variables for portable mode and profile isolation #8968: [FEATURE]: Support OPENCODE_CACHE_DIR and OPENCODE_LOG_DIR for full isolation - Related to XDG directory isolation concerns

The core issue appears to be that using ~/.agents/skills breaks XDG spec compliance. If #10986 hasn't been implemented yet, that's where the feature discussion should happen. If it has been implemented, the issue might be in how the path is currently being set up relative to XDG directories.

Feel free to ignore if none of these address your specific case.
