# Plan: Transpose Claude Code Setup to OpenCode (Parallel)

## Handoff Summary

**Goal**: Set up OpenCode in parallel with Claude Code, sharing state files and syncing agents/skills.

**Status**: ✅ **IMPLEMENTATION COMPLETE** (2026-01-07)

### Key Decisions Made

1. **Use built-in `build` agent** as primary (not porting `personal-assistant`)
2. **All agents synced as subagents** (SKIP_AGENTS kept empty for flexibility)
3. **Model inheritance** - subagents use runtime-selected model
4. **Claude Code is source of truth** - OpenCode references state files via `instructions`
5. **No JSON minification** needed (files too small, added to future considerations as fc-047)

### What Was Completed

| Step | Status | Notes |
|------|--------|-------|
| 1 | ✅ | Backups created (Jan 7 12:01) |
| 2 | ✅ | Sync script enhanced (mode:subagent, model removal) |
| 3 | ✅ | Sync run: 10 skills, 13 agents, 27 commands, 10 workflows |
| 4 | ✅ | opencode.json updated (instructions, permissions) |
| 5 | ✅ | Automated tests passed, manual TUI testing pending |
| 6 | ✅ | README.md created (4.7KB), fc-047 added |
| 7 | ⏳ | Iterate as needed |

### Critical Files

**Modified:**
- `~/.config/opencode/scripts/claude_sync.py` ✅ - Added mode:subagent, model removal, skip logic
- `~/.config/opencode/opencode.json` ✅ - Added instructions, permissions

**Created:**
- `~/.config/opencode/README.md` ✅ - Documentation (4.7KB)

**Referenced (not copied):**
- `~/.claude/CLAUDE.md`
- `~/.claude/state/kb.json`
- `~/.claude/state/personal-assistant/memory/*.json`

### Architecture

```
OpenCode (after implementation)
├── Primary: build (built-in), plan (built-in)
├── Subagents: @linux-sysadmin, @k8s-orchestrator, @code-reviewer, etc.
├── Skills: auto-discovered from ~/.claude/skills/
└── State: referenced via instructions from ~/.claude/state/
```

### Start Command

```bash
# Exit plan mode and begin implementation
# Step 1: Backup
BACKUP_DATE=$(date +%Y%m%d_%H%M%S)
tar -czvf ~/.config/opencode-backup-$BACKUP_DATE.tar.gz -C ~/.config opencode/
tar -czvf ~/opencode-home-backup-$BACKUP_DATE.tar.gz -C ~ .opencode/
```

---

## Goal

Create a parallel OpenCode configuration that shares/reuses as much of the existing Claude Code infrastructure as possible, focusing on:
1. **Skills/scripts execution** (highest priority)
2. **Agent hierarchy/delegation** (second priority)
3. **State persistence** (if low complexity)

## Key Discovery: Native Compatibility

OpenCode **natively supports Claude-compatible skill paths**:
- `~/.claude/skills/<name>/SKILL.md` - Already supported!
- This means your 11 existing skills can work with minimal changes

---

## Phase 0: Backup Existing OpenCode Setup

### Current State Discovered

OpenCode is already installed with substantial configuration:

**`~/.config/opencode/`** (main config):
- `opencode.json` - Has `claude-sync` command already!
- `agent/` - 3 custom agents (coding-expert, k8s-expert, tdd-enforcer)
- `agents/` - 12 synced Claude Code agents (already converted!)
- `skills/` - 10 skills (some synced, one symlink to morning-report)
- `scripts/claude_sync.py` - Existing sync script!

**`~/.opencode/`** (alternate config):
- `agent/` - 4 different agents (openagent, system-builder, etc.)
- `command/` - 12 commands (commit, optimize, validate-repo, etc.)

### Backup Commands

```bash
# Create timestamped backups
BACKUP_DATE=$(date +%Y%m%d_%H%M%S)

# Backup ~/.config/opencode/
tar -czvf ~/.config/opencode-backup-$BACKUP_DATE.tar.gz -C ~/.config opencode/

# Backup ~/.opencode/
tar -czvf ~/opencode-home-backup-$BACKUP_DATE.tar.gz -C ~ .opencode/

# Verify backups
ls -la ~/.config/opencode-backup-*.tar.gz ~/opencode-home-backup-*.tar.gz
```

---

## Phase 1: Use Existing `claude_sync.py` Script

The existing sync script is **comprehensive** and handles:

| Category | Source | Destination | Transforms |
|----------|--------|-------------|------------|
| Skills | `~/.claude/skills/*/SKILL.md` | `~/.config/opencode/skills/*/SKILL.md` | `allowed-tools` → `metadata.claude_allowed_tools` |
| Agents | `~/.claude/agents/*.md` | `~/.config/opencode/agents/*.md` | `tools: X, Y` → `tools: { x: true, y: true }` |
| Commands | `~/.claude/commands/*.md` | `~/.config/opencode/claude/commands/*.md` | None |
| Workflows | `~/.claude/workflows/*.yaml` | `~/.config/opencode/claude/workflows/*.yaml` | None |

### Sync Commands

```bash
# Dry run - see what would change
python3 ~/.config/opencode/scripts/claude_sync.py --dry-run

# Actually sync
python3 ~/.config/opencode/scripts/claude_sync.py

# Clean stale files (dry run first)
python3 ~/.config/opencode/scripts/claude_sync.py --clean --dry-run
python3 ~/.config/opencode/scripts/claude_sync.py --clean --apply

# Sync specific category only
python3 ~/.config/opencode/scripts/claude_sync.py --only agents
```

### Model Mapping Update Needed

Current script maps old models. May need to add:
- `opus` → `anthropic/claude-opus-4`
- `sonnet` → `anthropic/claude-sonnet-4-5`
- `haiku` → `anthropic/claude-haiku-4-5`

---

## Phase 1.5: OpenCode Optimization (NEW)

The current sync just copies/transforms files. It doesn't optimize for **how OpenCode works**.

### Key OpenCode Differences

| Concept | Claude Code | OpenCode | Optimization Needed |
|---------|-------------|----------|---------------------|
| **Agent hierarchy** | PA → MO → agents | Flat: primary + subagents | Add `mode` field |
| **Agent invocation** | Delegation patterns | `@agent` mentions | Simplify prompts |
| **Permissions** | Hooks + guardrails | `permission` config | Move to opencode.json |
| **Model selection** | Per-agent in frontmatter | `model: inherit` option | Use inheritance |
| **Auto-invocation** | Keyword triggers in registry | Rich `description` field | Enhance descriptions |

### Agent Mode Assignment

```yaml
# PRIMARY - Use OpenCode's built-in agents
build: (built-in)     # Full access, default primary
plan:  (built-in)     # Read-only analysis

# SKIP - Not needed in OpenCode's flat model
personal-assistant:    # Use built-in "build" instead
master-orchestrator:   # Intermediary not needed

# SUBAGENTS (invoked via @mention or Task tool)
linux-sysadmin:        mode: subagent
k8s-orchestrator:      mode: subagent
k8s-diagnostician:     mode: subagent
argocd-operator:       mode: subagent
prometheus-analyst:    mode: subagent
git-operator:          mode: subagent
programmer-orchestrator: mode: subagent
code-planner:          mode: subagent
code-implementer:      mode: subagent
code-reviewer:         mode: subagent
```

### Hierarchy Simplification

**Claude Code pattern** (complex, 3 layers):
```
User → Personal Assistant → Master Orchestrator → linux-sysadmin
                                                → k8s-orchestrator → k8s-diagnostician
```

**OpenCode pattern** (flat, 2 layers):
```
User → build (built-in) → @linux-sysadmin
                        → @k8s-orchestrator
                        → @k8s-diagnostician
                        → @code-reviewer
                        → etc.
```

Benefits:
- No custom primary agent to maintain
- Built-in `build` agent is optimized for OpenCode
- Built-in `plan` agent available for read-only analysis
- Subagents invoked directly via @mention

### Sync Script Enhancements Needed

Update `claude_sync.py` to add:

```python
# In transform_frontmatter() for agents:

# 1. Skip agents not needed in OpenCode's flat model
SKIP_AGENTS = {"personal-assistant", "master-orchestrator"}

if name in SKIP_AGENTS:
    return None  # Signal to skip this file

# 2. All synced agents become subagents (built-in build/plan are primary)
frontmatter["mode"] = "subagent"

# 3. Use model inheritance (subagents use parent's model)
frontmatter["model"] = "inherit"

# 4. Map explicit models if not using inherit
MODEL_MAP = {
    "opus": "anthropic/claude-opus-4",
    "sonnet": "anthropic/claude-sonnet-4-5",
    "haiku": "anthropic/claude-haiku-4-5",
}
if frontmatter.get("model") in MODEL_MAP:
    frontmatter["model"] = MODEL_MAP[frontmatter["model"]]
```

Also update `sync_tree()` to handle `None` return (skip file).

### Description Enhancement

OpenCode uses descriptions for **auto-invocation**. Enhance with examples:

**Current** (basic):
```yaml
description: Manages Arch Linux workstation - system maintenance...
```

**Optimized** (with examples):
```yaml
description: |
  Manages Arch Linux workstation. Use for system maintenance, updates,
  troubleshooting, and health checks.
  Examples:
  - "check system health" → @linux-sysadmin
  - "update packages" → @linux-sysadmin
  - "why is my disk full" → @linux-sysadmin
```

### Permission Migration

Move guardrail logic to opencode.json:

```json
{
  "permission": {
    "edit": "ask",
    "bash": {
      "*": "ask",
      "pacman -Q*": "allow",
      "systemctl status*": "allow",
      "kubectl get*": "allow",
      "git status": "allow",
      "git diff": "allow"
    }
  }
}
```

---

## Phase 2: Create OpenCode Config Structure

### Directory Layout

```
~/.config/opencode/
├── opencode.json          # Main config
├── AGENTS.md              # Global rules (symlink or copy from CLAUDE.md)
├── agent/                 # Agent definitions
│   ├── personal-assistant.md
│   ├── linux-sysadmin.md
│   ├── k8s-orchestrator.md
│   └── ... (converted agents)
├── tool/                  # Custom tool wrappers (TypeScript)
│   ├── gmail.ts           # Wrapper for gmail scripts
│   ├── gcal.ts            # Wrapper for gcal scripts
│   └── ...
└── skill/                 # OpenCode-native skills (optional)
```

### Config File: `~/.config/opencode/opencode.json`

```jsonc
{
  "$schema": "https://opencode.ai/config.json",
  "model": "anthropic/claude-sonnet-4-5",
  "small_model": "anthropic/claude-haiku-4-5",
  "autoupdate": true,

  // OpenCode already searches ~/.claude/skills/ - no extra config needed!

  // Agent definitions
  "agent": {
    // Override built-in agents or define custom via files
  },

  // Default permissions (conservative like your current setup)
  "permission": {
    "edit": "ask",
    "bash": "ask"
  },

  // Custom tools enabled
  "tools": {
    "gmail": true,
    "gcal": true,
    "gtasks": true
  }
}
```

---

## Phase 3: Skills Migration

### Already Compatible (No Changes Needed)

OpenCode automatically discovers skills from:
- `~/.claude/skills/*/SKILL.md`

Your existing skills should work if they have proper frontmatter:

| Skill | Status | Notes |
|-------|--------|-------|
| gmail | Check frontmatter | Needs `name` + `description` |
| gcal | Check frontmatter | Needs `name` + `description` |
| gtasks | Check frontmatter | Needs `name` + `description` |
| sysadmin-health | Check frontmatter | |
| k8s-quick-status | Check frontmatter | |
| morning-report | Check frontmatter | |
| stock-lookup | Check frontmatter | |
| rag-search | Check frontmatter | |
| usage | Check frontmatter | |
| guardrails | N/A | Becomes permission config |

### Frontmatter Requirements

Each SKILL.md needs:
```yaml
---
name: skill-name          # Required, must match directory name
description: Brief desc   # Required, 1-1024 chars
---
```

### Audit Results (Already Compatible!)

Checked skills have proper frontmatter:
- `gmail/SKILL.md` - Has `name: gmail`, `description: ...`
- `sysadmin-health/SKILL.md` - Has `name: sysadmin-health`, `description: ...`
- `morning-report/SKILL.md` - Has `name: morning-report`, `description: ...`

The `allowed-tools` field in some skills will be ignored by OpenCode (not in their schema), but this is fine.

### Action Items

1. ~~Audit each SKILL.md for required frontmatter~~ **Done - already compatible!**
2. ~~Add missing `name`/`description` fields~~ **Not needed**
3. Test skill discovery in OpenCode after install

---

## Phase 4: Agent Migration

### Mapping Strategy

| Claude Code | OpenCode | Notes |
|------------|----------|-------|
| `model: opus` | `model: anthropic/claude-opus-4` | Full provider/model path |
| `model: sonnet` | `model: anthropic/claude-sonnet-4-5` | |
| `model: haiku` | `model: anthropic/claude-haiku-4-5` | |
| `tools: Read, Write...` | `tools: { write: true, ... }` | Boolean map |
| Hierarchy (PA → MO → agent) | `mode: primary` + `mode: subagent` | Flattened |

### Agent Conversion Template

**From (Claude Code):**
```yaml
---
name: linux-sysadmin
description: Manages Arch Linux workstation...
model: sonnet
tools: Bash, Read, Write, Edit, Grep, Glob
---
```

**To (OpenCode):**
```yaml
---
name: linux-sysadmin
description: Manages Arch Linux workstation...
mode: subagent
model: anthropic/claude-sonnet-4-5
tools:
  bash: true
  read: true
  write: true
  edit: true
permission:
  bash:
    "*": ask
    "pacman -Q*": allow
    "systemctl status*": allow
---
```

### Priority Agents to Convert

1. **personal-assistant.md** → `mode: primary` (main interface)
2. **linux-sysadmin.md** → `mode: subagent`
3. **k8s-orchestrator.md** → `mode: subagent`
4. **master-orchestrator.md** → May not be needed (OpenCode doesn't have same hierarchy)

### Hierarchy Adaptation

OpenCode doesn't have hierarchical agent delegation like your current setup. Options:
- **Option A**: Flatten to primary + subagents, use `@agent` mentions
- **Option B**: Use OpenCode's Task tool for agent invocation
- **Option C**: Create a "dispatcher" primary agent that routes via @mentions

**Recommendation**: Option A (simplest) - personal-assistant as primary, others as subagents invokable via `@linux-sysadmin`, `@k8s-orchestrator`, etc.

---

## Phase 5: Custom Tools (Scripts Execution)

### Wrapper Pattern

Create TypeScript wrappers that invoke your existing Python scripts:

**Example: `~/.config/opencode/tool/gmail.ts`**

```typescript
import { tool } from "@opencode-ai/plugin"

export const check_unread = tool({
  description: "Check unread emails from Gmail",
  args: {
    limit: tool.schema.number().optional().describe("Max emails to return"),
  },
  async execute(args) {
    const limit = args.limit ?? 10
    const result = await Bun.$`~/.claude/mcp/gmail/venv/bin/python ~/.claude/skills/gmail/scripts/check_unread.py --limit ${limit}`.text()
    return result.trim()
  },
})

export const search = tool({
  description: "Search Gmail for specific emails",
  args: {
    query: tool.schema.string().describe("Search query"),
  },
  async execute(args) {
    const result = await Bun.$`~/.claude/mcp/gmail/venv/bin/python ~/.claude/skills/gmail/scripts/search.py "${args.query}"`.text()
    return result.trim()
  },
})
```

### Tools to Create Wrappers For

| Script | Wrapper |
|--------|---------|
| `gmail/scripts/*.py` | `gmail.ts` |
| `gcal/scripts/*.py` | `gcal.ts` |
| `gtasks/scripts/*.py` | `gtasks.ts` |
| `sysadmin-health/scripts/*.sh` | `sysadmin.ts` |
| `morning-report/scripts/*.py` | `morning.ts` |
| `stock-lookup/scripts/*.py` | `stocks.ts` |

---

## Phase 6: Rules/Instructions

### Option A: Symlink CLAUDE.md

```bash
ln -s ~/.claude/CLAUDE.md ~/.config/opencode/AGENTS.md
```

### Option B: Create Minimal AGENTS.md + Reference

```markdown
# OpenCode Agent Rules

Read @~/.claude/CLAUDE.md for shared conventions.

## OpenCode-Specific

- Use `@agent-name` to invoke subagents
- Skills are loaded via the `skill` tool
- Custom tools available: gmail, gcal, gtasks, sysadmin
```

### Option C: Use instructions config

```json
{
  "instructions": ["~/.claude/CLAUDE.md", "~/.claude/state/system-instructions.json"]
}
```

**Recommendation**: Option C - cleanest, no duplication

---

## Phase 7: State Persistence (Claude Code as Source of Truth)

### Strategy

Claude Code owns the state files. OpenCode reads them via:
1. `{file:path}` variable substitution in `opencode.json`
2. `instructions` array for context files
3. Skills that read state files directly

### What Can Be Shared

| File | Method | Notes |
|------|--------|-------|
| `~/.claude/CLAUDE.md` | `instructions` | Global rules |
| `~/.claude/state/kb.json` | `instructions` or skill | Knowledge base |
| `~/.claude/state/personal-assistant/memory/*.json` | `instructions` | Memory context |
| `~/.claude/state/system-instructions.json` | `instructions` | Process definitions |

### Implementation in `opencode.json`

```jsonc
{
  "$schema": "https://opencode.ai/config.json",

  // Load Claude Code state as instructions (read at session start)
  "instructions": [
    "~/.claude/CLAUDE.md",
    "~/.claude/state/kb.json",
    "~/.claude/state/personal-assistant/memory/facts.json",
    "~/.claude/state/personal-assistant/memory/preferences.json"
  ]
}
```

### What Stays Separate

| Item | Reason |
|------|--------|
| Session history | Different formats, different storage |
| Autonomy/permissions | OpenCode uses `permission` config instead |
| Component registry | OpenCode discovers via file paths |

### Overhead Assessment

**Low overhead** - just config changes:
- Add paths to `instructions` array
- No symlinks or sync scripts needed
- OpenCode reads files directly at session start
- Claude Code continues to write/update normally

---

## Phase 8: What Won't Transfer

| Feature | Claude Code | OpenCode Alternative |
|---------|-------------|---------------------|
| Hooks (SessionStart, etc.) | `hooks/hooks.json` | Plugins (future) |
| Guardrails hook | PreToolUse script | `permission` config |
| Component registry routing | Keyword triggers | Agent descriptions + @mentions |
| Hierarchical delegation | PA → MO → agent | Flat subagent model |

---

## Implementation Order

### Step 1: Backup (5 min) ✅ COMPLETE
- [x] Create timestamped backup of `~/.config/opencode/` → `opencode-backup-20260107_120135.tar.gz`
- [x] Create timestamped backup of `~/.opencode/` → `opencode-home-backup-20260107_120136.tar.gz`

### Step 2: Enhance Sync Script (45 min) ✅ COMPLETE
- [x] Add skip list: `SKIP_AGENTS` (kept empty - all agents synced as subagents)
- [x] Add `mode: subagent` to all synced agents
- [x] Remove hardcoded model (agents inherit from runtime selection)
- [x] Add model stripping from opencode.json
- [x] Update `sync_tree()` to handle skipped files
- [ ] ~~Optionally enhance descriptions with examples~~ (deferred)

### Step 3: Run Enhanced Sync (10 min) ✅ COMPLETE
- [x] `python3 ~/.config/opencode/scripts/claude_sync.py --dry-run`
- [x] Review output - verify mode/model changes
- [x] `python3 ~/.config/opencode/scripts/claude_sync.py`
- [x] All synced: 10 skills, 13 agents, 27 commands, 10 workflows

### Step 4: Update opencode.json (20 min) ✅ COMPLETE
- [x] Add `instructions` array (CLAUDE.md, kb.json, memory files)
- [x] Model defaults: intentionally omitted (user selects at runtime)
- [x] Add permission config with safe command patterns

### Step 5: Testing (30 min) ✅ COMPLETE (automated)
- [x] OpenCode v1.0.220 installed at `/home/linuxbrew/.linuxbrew/bin/opencode`
- [x] `opencode agent list` shows 40 agents (built-in + synced)
- [x] All Claude Code agents show as `(subagent)`
- [x] 10 skills synced to `~/.config/opencode/skills/`
- [x] Config verified: instructions, permissions, commands present
- [ ] Manual TUI testing (user to verify interactively)

### Step 6: Documentation (20 min) ✅ COMPLETE
- [x] Create `~/.config/opencode/README.md` (4.7KB)
- [x] Document complete agent mapping table
- [x] Document sync workflow with examples
- [x] Add fc-047 to `~/.claude/state/future-considerations.json`

### Step 7: Iterate (as needed) ⏳ PENDING
- [ ] Adjust agent descriptions if auto-invocation isn't working well
- [ ] Tune permission patterns
- [ ] Consider dropping/hiding agents that don't fit OpenCode model
- [ ] Update documentation with lessons learned

**Status: IMPLEMENTATION COMPLETE** - Manual TUI testing recommended

---

## Phase 8: Documentation

### Documentation Deliverables

Create `~/.config/opencode/README.md` with:

1. **Architecture Overview**
   - Relationship between Claude Code and OpenCode
   - What's shared vs separate
   - Source of truth (Claude Code)

2. **Sync Workflow**
   - How `claude_sync.py` works
   - When to run it (after Claude Code changes)
   - Command reference

3. **Agent Mapping**
   - Which Claude Code agents map to OpenCode
   - Which are skipped and why
   - How to invoke subagents (@mentions)

4. **Skills**
   - Auto-discovery from `~/.claude/skills/`
   - How to add new skills
   - Skill invocation patterns

5. **State Sharing**
   - Files referenced via `instructions`
   - Claude Code as source of truth
   - What stays separate

6. **Permissions**
   - How guardrails translated to `permission` config
   - Safe vs prompted commands

### Documentation Template

```markdown
# OpenCode Configuration

This OpenCode setup is synchronized from Claude Code (`~/.claude/`).

## Quick Start

```bash
# Start OpenCode (uses built-in build agent)
opencode

# Switch to read-only plan agent
# Press Tab

# Invoke a subagent
@linux-sysadmin check system health
```

## Architecture

```
Claude Code (source of truth)
├── ~/.claude/agents/          → synced to ~/.config/opencode/agents/
├── ~/.claude/skills/          → synced to ~/.config/opencode/skills/
├── ~/.claude/CLAUDE.md        → referenced via instructions
└── ~/.claude/state/           → referenced via instructions

OpenCode
├── Built-in: build (primary), plan (read-only)
├── Subagents: @linux-sysadmin, @k8s-orchestrator, etc.
└── Skills: gmail, gcal, sysadmin-health, etc.
```

## Sync Workflow

After making changes in Claude Code:

```bash
# Preview changes
python3 ~/.config/opencode/scripts/claude_sync.py --dry-run

# Apply changes
python3 ~/.config/opencode/scripts/claude_sync.py

# Clean stale files
python3 ~/.config/opencode/scripts/claude_sync.py --clean --apply
```

## Agents

| Claude Code | OpenCode | Notes |
|-------------|----------|-------|
| personal-assistant | (skipped) | Use built-in `build` |
| master-orchestrator | (skipped) | Flat model, not needed |
| linux-sysadmin | @linux-sysadmin | Subagent |
| k8s-orchestrator | @k8s-orchestrator | Subagent |
| ... | ... | ... |

## Skills

Skills are auto-discovered from:
- `~/.claude/skills/*/SKILL.md`
- `~/.config/opencode/skills/*/SKILL.md`

## State Files

Referenced via `instructions` in opencode.json:
- `~/.claude/CLAUDE.md` - Global rules
- `~/.claude/state/kb.json` - Knowledge base
- `~/.claude/state/personal-assistant/memory/*.json` - Memory

## Permissions

Configured in opencode.json `permission` section.
Migrated from Claude Code's guardrail hooks.
```

### Implementation Step

Add to Step 6:
- [ ] Create `~/.config/opencode/README.md`
- [ ] Document sync workflow
- [ ] Document agent mapping
- [ ] Document any gotchas discovered during testing

---

## Files to Create/Modify

### Files to Create
- `~/.config/opencode/README.md` - Documentation of setup, workflow, and requirements

### Files to Modify
- `~/.config/opencode/opencode.json` - Add `instructions` array + model/permission config
- `~/.config/opencode/scripts/claude_sync.py` - Add mode, model mappings, skip list

### Files Auto-Synced by Script
These are created/updated by `claude_sync.py`:
- `~/.config/opencode/agents/*.md` - From `~/.claude/agents/`
- `~/.config/opencode/skills/*/SKILL.md` - From `~/.claude/skills/`
- `~/.config/opencode/claude/commands/*.md` - From `~/.claude/commands/`
- `~/.config/opencode/claude/workflows/*.yaml` - From `~/.claude/workflows/`

### Files Referenced (Not Copied)
These stay in Claude Code, referenced via `instructions`:
- `~/.claude/CLAUDE.md`
- `~/.claude/state/kb.json`
- `~/.claude/state/personal-assistant/memory/*.json`

---

## Success Criteria

1. `opencode` launches and shows available skills
2. Can invoke `@linux-sysadmin` and get expected behavior
3. Gmail/GCal/GTasks tools work via custom wrappers
4. Can switch between build/plan agents + custom agents
5. Both Claude Code and OpenCode can run in parallel without conflicts
