Project agents not loaded - silent failure on startup and auto-compact

Description

Project-level agents (.claude/agents/*.md) fail to load silently without any error messages. This issue occurs particularly after auto-compact or when restarting Claude Code.

Environment

• Platform: macOS (Darwin 24.5.0)
• Claude Code version: Latest
• Working directory: Consistent, no path changes

Symptoms

1. No error messages - Completely silent failure
2. @ autocomplete - Only shows user agents (~/.claude/agents/), project agents don't appear
3. /context command - Project agents section is completely missing (not empty, but absent)
4. User agents work fine - All agents in ~/.claude/agents/ load correctly

Steps to Reproduce

1. Create project agents in .claude/agents/*.md
2. Start Claude Code in the project directory
3. Wait for auto-compact to occur, OR restart Claude Code
4. Run /context - project agents section is missing
5. Try @ autocomplete - only user agents appear

Expected Behavior

• Project agents should load from .claude/agents/
• Should appear in /context output under "Project" section
• Should be available in @ autocomplete
• If loading fails, should show an error message

Actual Behavior

• Project agents silently fail to load
• No error messages in any output
• Only user-level agents (~/.claude/agents/) are recognized
• /context shows all agents as "(User)" scope

Current Workaround

Moving all agents to user scope (~/.claude/agents/) works reliably.

Additional Context

This appears to be a loading order or initialization issue. The problem is more frequent after:

• Auto-compact events
• Claude Code restarts
• Long-running sessions

The silent failure makes debugging difficult - users don't know if:

• Agents aren't loaded
• Path is wrong
• File format is invalid
