## Request Parsing

| Element | Parsed Value |
|---------|-------------|
| Target PRDs | issue #24, issue #28 (explicit selection) |
| Profile override | `xhigh` -> `codex53_xhigh` for both |
| OMX skill override | `$ralph` for both ("끝까지 돌려" = run to completion) |
| Execution mode | `--full-auto` (default) |

## Skill Workflow Trace

### Step 1: Scan
- Scanned `.omx/plans/*.md` -- found 7 PRDs (issues 24-30)
- User specified issues 24 and 28 only -- 5 PRDs skipped

### Step 2: Selection
- User explicitly named issue 24 and 28 -- no AskUserQuestion needed
- Bypassed interactive selection entirely

### Step 3: Classification
- Both PRDs analyzed for content keywords
- Issue #24: keywords "추가", "변경" -> **implement**
- Issue #28: keywords "fix", "변경", "추가" -> **implement**
- Auto skill would be `$plan` -> `$autopilot` for both
- **User override: `$ralph`** -- takes precedence, no AskUserQuestion

### Step 4: Profile Routing
- Issue #24: 73 lines, 4 files, 0 high-cost keywords -> **L (standard)**
- Issue #28: 68 lines, 3 files, 0 high-cost keywords -> **L (standard)**
- Auto profile for implement/L = `codex53_high`
- **User override: `codex53_xhigh`** -- takes precedence, no AskUserQuestion

### Step 5: Worktree
- 2 worktrees to create: `.codex-swarm/wt-issue-24`, `.codex-swarm/wt-issue-28`
- Branch naming: `codex/issue-24`, `codex/issue-28`

### Step 6: Prompts
- 2 prompt files generated in `.codex-swarm/prompts/`
- Each prompt includes: PRD path reference, `$ralph` skill instruction, verification steps
- PRD files copied into respective worktrees

### Step 7: psmux + Codex
- 2 psmux sessions: `codex-swarm-24`, `codex-swarm-28`
- Codex flags: `-c 'model="gpt-5.3-codex"' -c 'model_reasoning_effort="xhigh"' --full-auto`
- Launch via `psmux send-keys` for interactive mode (OMX skill requires interactive)

### Step 8: WT Attach
- First session opens new WT window
- Second session attaches as tab in same window
- Fallback: direct `wt.exe` command included

## Override Impact Analysis

### Profile override: codex53_high -> codex53_xhigh

| Metric | codex53_high | codex53_xhigh | Delta |
|--------|-------------|---------------|-------|
| Model | gpt-5.3-codex | gpt-5.3-codex | same |
| Reasoning effort | high | xhigh | +1 tier |
| Expected token cost | ~1x | ~1.5-2x | higher |
| Expected quality | standard | maximum | better for complex tasks |

The override is reasonable: both PRDs involve non-trivial implementation work across multiple files with edge-case handling (path normalization, cross-shell quoting for #24; guard decision matrix testing for #28). The `xhigh` reasoning effort gives the model more room to handle these nuances correctly.

### Skill override: $autopilot -> $ralph

| Aspect | $autopilot | $ralph |
|--------|-----------|--------|
| Planning | yes | yes |
| Execution | single pass | iterative until completion |
| Verification | basic | full loop |
| Recovery | manual | automatic retry |

The override is well-suited: `$ralph` ("끝까지 돌려") ensures each session runs its implementation to completion with verification loops, rather than stopping after a single autopilot pass. For issues that have clear acceptance criteria (both PRDs do), this maximizes the probability of a fully-resolved branch.

## Resource Summary

| Resource | Count |
|----------|-------|
| Worktrees | 2 |
| psmux sessions | 2 |
| WT tabs | 2 (1 window) |
| Codex instances | 2 (parallel) |
| Profile | codex53_xhigh x2 |
| Branches | `codex/issue-24`, `codex/issue-28` |

## Post-Spawn Actions (Step 10)

After both sessions complete, the user can:
1. **Status check**: `psmux capture-pane --session "codex-swarm-{24,28}" --lines 5`
2. **Merge results**: `git merge codex/issue-24 && git merge codex/issue-28`
3. **Cleanup**: `psmux kill-session --name "codex-swarm-*" && git worktree prune && rm -rf .codex-swarm/`
