opencode doesn't respect CLAUDE_CONFIG_DIR environment variable

[ramarivera]

Problem

Opencode hardcodes ~/.claude as the path for reading Claude Code configuration (CLAUDE.md and skills), but Claude Code v1.0.30+ changed its default config directory to ~/.config/claude and added support for the CLAUDE_CONFIG_DIR environment variable to override this.

This causes issues for users who:

1. Use CLAUDE_CONFIG_DIR to specify a custom config location
2. Have a file (not directory) at ~/.claude, causing ENOTDIR errors when opencode tries to glob inside it

Expected Behavior

Opencode should check for Claude config in this order:

1. CLAUDE_CONFIG_DIR environment variable (if set and is a valid directory)
2. ~/.config/claude (new Claude Code default)
3. ~/.claude (legacy path)

Affected Code

• packages/opencode/src/session/system.ts - hardcodes ~/.claude/CLAUDE.md
• packages/opencode/src/skill/skill.ts - hardcodes ~/.claude for skills

References

• Claude Code configuration docs: https://docs.anthropic.com/en/docs/claude-code/settings
• Claude Code v1.0.30 changed default from ~/.claude to ~/.config/claude

Also hitting this via Anthropic Subscription (OAuth). When using Opus or Sonnet directly, OpenCode falls back to the hardcoded legacy config path instead of respecting the .opencode/ directory structure. Combined with #10567 (string replacement of "opencode" in paths), this creates a situation where config, agents and rules are read from and written to the wrong location entirely — making it impossible to rely on a consistent setup when switching models.
