# OMO-Paseo Bridge Design

## Architecture

```
OpenCode Session (Atlas)
│
├── task() ──► child session (ses_xxx) ──► OMO subagent does work
│                  │
│                  ▼
│           omo-paseo-bridge skill
│           paseo import <ses_xxx> --provider opencode --label omo=true
│                  │
│                  ▼
│           Paseo Daemon (~/.paseo/agents/<cwd>/<uuid>.json)
│           Agent appears in `paseo ls`
│
├── task completes ──► child session finishes
│                  │
│                  ▼
│           paseo archive <ses_xxx> (cleans up)
│
└── Verification ──► paseo ls --json | jq '.[] | select(.labels.omo)'
```

## Three Integration Points

### 1. Atlas Prompt Instruction (immediate, zero-code)

Add to the Atlas orchestration prompt:

```
## Paseo Bridge Protocol
When you call task() and receive a child session ID:
  - On task creation: `paseo import <session-id> --provider opencode --label omo=true --label type=<category>`
  - On task completion: Track the session ID; clean up later
```

**Pros:** Zero code changes, works immediately
**Cons:** Ephemeral (per-session context), must be repeated every session

### 2. OpenCode Skill (durable, scripted)

Create a reusable skill at `.opencode/skills/omo-paseo-bridge/SKILL.md` that:

- Accepts a child session ID and task type
- Calls `paseo import` with proper labels
- Returns the imported agent ID
- Handles errors (daemon not running, already imported)

The Atlas prompt calls this skill instead of shelling out directly.

### 3. PreToolUse Hook (fully automatic)

A hook that intercepts `task()` calls before/after execution:

- On `task()` launch: capture the session ID from the response
- On `task()` completion: `paseo archive` the corresponding agent

**Pros:** Fully automatic, no prompt changes needed
**Cons:** Hook system support varies by runtime

## Data Model

```typescript
// Labels applied to each imported Paseo agent
{
  "omo": "true",
  "omo.type": "explore | quick | ultrabrain | deep | visual-engineering | unspecified-low | unspecified-high | writing", 
  "omo.parent_session": "ses_xxx",    // The session that called task()
  "omo.description": "Search codebase for X"  // The task prompt description
}
```

## CLI Bridge Script (Optional)

A small `omo-paseo` CLI that wraps common operations:

```bash
# Import all unregistered child sessions
omo-paseo sync

# Clean up completed/failed OMO agents
omo-paseo prune

# Show OMO agents in paseo format
omo-paseo ls
```
