[Bug] 'Claude' injected into file paths by subagents (recurring)

[randomm]

Summary

Subagents are accessing paths with 'Claude' injected into them, e.g.:

• ~/git/Claude/packages/opencode/src/session instead of ~/git/opencode/packages/opencode/src/session

This is a recurring issue that has been fixed before but keeps reappearing.

Reproduction

• Run opencode from ~/git/opencode
• Launch a subagent task that reads files
• Observe permission prompt shows ~/git/Claude/... path

Expected

Paths should use the actual working directory: ~/git/opencode/...

Likely cause

The LLM (Claude) may be hallucinating its own name into paths, OR there's a config/prompt that references 'Claude' as a directory name. Could also be a stale reference in AGENTS.md, session context, or instance directory resolution.

Previous fixes

This has been fixed multiple times already — check git history for prior approaches.

Investigation Findings

Root cause: LLM hallucination, not a code bug.

The directory inheritance code is correct (fixed in commit 6981429). The LLM hallucinates 'Claude' into paths because:

1. ~/.config/opencode/CLAUDE.md is loaded as custom instructions — contains 'Claude Code' references
2. Model name 'claude-opus' appears in context
3. System prompts reference 'Claude Code'
4. The LLM conflates these with directory structure and fabricates ~/git/Claude

No /git/Claude path exists anywhere in code or config.

Options:

1. Rename global CLAUDE.md to AGENTS.md (reduces 'Claude' mentions)
2. Add explicit path reinforcement in subagent system prompt
3. Accept as inherent LLM behavior (model hallucination)

This is a prompt engineering issue, not a code bug. The working directory IS correctly passed to subagents via Instance.directory.
