**Date:** 2026-01-09
**Status:** ✅ Complete
**Deliverables:** 4 comprehensive documents + shared knowledge graph

## What Was Researched

### Primary Questions
1. How does Luzia handle interactive prompts to prevent agent blocking?
2. What patterns enable autonomous agent execution without user input?
3. How do agents handle clarification needs without blocking?
4. What are best practices for prompt design in autonomous agents?

### Secondary Questions
5. How does the Claude Agent SDK prevent approval dialog blocking?
6. What communication patterns work for async agent-to-user interaction?
7. How can agents make decisions without asking for confirmation?

## Key Findings

### 1. **Blocking is Prevented Through Architecture, Not Tricks**

Luzia prevents agent blocking through four **architectural layers**:

| Layer | Implementation | Purpose |
|-------|---|---|
| **Process** | Detached spawning (`nohup ... &`) | Parent CLI returns immediately |
| **Permission** | `--permission-mode bypassPermissions` | No approval dialogs shown |
| **Communication** | File-based IPC (job directory) | No stdin/stdout dependencies |
| **Status** | Exit code signaling (append to log) | Async status queries |

**Result:** Even if an agent wanted to block, it can't because:
- It's in a separate process (parent is gone)
- It doesn't have stdin (won't wait for input)
- Permission mode prevents approval prompts

### 2. **The Golden Rule of Autonomy**

> **Autonomous agents don't ask for input because they don't need to.**

Well-designed prompts provide:
- ✓ Clear, specific objectives (not "improve code", but "reduce complexity to < 5")
- ✓ Defined success criteria (what success looks like)
- ✓ Complete context (environment, permissions, constraints)
- ✓ No ambiguity (every decision path covered)

When these are present → agents execute autonomously
When these are missing → agents ask questions → blocking occurs

### 3. **Five Critical Patterns Emerged**

1. **Detached Spawning**: Run agents as background processes
   - Returns immediately to CLI
   - Agents continue independently
   - PID tracked for monitoring

2. **Permission Bypass**: Use `--permission-mode bypassPermissions`
   - No approval dialogs for tool use
   - Safe because scope limited (project user, project dir)
   - Must grant pre-authorization in prompt

3. **File-Based I/O**: Use job directory as IPC channel
   - Prompt input via file
   - Output captured to log
   - Status queries don't require process
   - Works with background agents

4. **Exit Code Signaling**: Append "exit:{code}" to output
   - Status persists in file after process ends
   - Async status queries (no polling)
   - Enables retry logic based on code

5. **Context-First Prompting**: Provide all context upfront
   - Specific task descriptions
   - Clear success criteria
   - No ambiguity
   - Minimize clarification questions

### 4. **The AskUserQuestion Problem**

Claude's `AskUserQuestion` tool blocks agent waiting for stdin:

```python
# This blocks forever if agent is backgrounded
response = await ask_user_question(
    question="What should I do here?",
    options=[...]
)
# stdin unavailable = agent stuck
```

**Solution:** Don't rely on user questions. Design prompts to be self-contained.

### 5. **Job Lifecycle is the Key**

Luzia's job directory structure enables full autonomy:

```
/var/log/luz-orchestrator/jobs/{job_id}/
├── prompt.txt         # Agent reads from here
├── output.log         # Agent writes to here (+ exit code)
├── meta.json          # Job metadata
├── run.sh             # Execution script
└── results.json       # Agent-generated results
```

Exit code appended to output.log as: `exit:{code}`

This enables:
- Async status queries (no blocking)
- Automatic retry on specific codes
- Failure analysis without process
- Integration with monitoring systems

## Implementation Checklist

### For Using These Patterns

- [ ] **Read** `AGENT-AUTONOMY-RESEARCH.md` sections 1-3 (understand architecture)

- [ ] **Write** prompts following `AGENT-CLI-PATTERNS.md` template
- [ ] **Use** templates from `AUTONOMOUS-AGENT-TEMPLATES.md` as starting point
- [ ] **Check** prompt against `AGENT-CLI-PATTERNS.md` checklist
- [ ] **Spawn** using `spawn_claude_agent()` function

### For Creating Custom Agents

When creating new autonomous agents:

1. **Define Success Clearly** - What does completion look like?
2. **Provide Context** - Full environment description
3. **Specify Format** - What output format (JSON, text, files)
4. **No Ambiguity** - Every decision path covered
5. **Document Constraints** - What can/can't be changed
6. **Define Exit Codes** - 0=success, 1=recoverable failure, 2=error
7. **No User Prompts** - All decisions made by agent alone
8. **Test in Background** - Verify no blocking

## Conclusion

Autonomous agents don't require complex async prompting systems. Instead, they require:

1. **Clear Architecture** - Detached processes, permission bypass, file IPC
2. **Good Prompts** - Specific, complete context, clear success criteria
3. **Exit Code Signaling** - Status persisted in files for async queries

Luzia implements all three. The findings in these documents provide patterns and best practices for anyone building autonomous agents with Claude.

**Key Insight:** The best way to avoid blocking is to design prompts that don't require user input. Luzia's architecture makes this pattern safe and scalable.
