OpenCode Sync Verification Checklist

Manual test checklist for OpenCode sync feature PR

1. Pre-check

1.1 Backup Files Path

• Verify backup suffix: .antigravity-manager.bak (new) and .antigravity.bak (legacy)
• Verify backup location: ~/.config/opencode/opencode.json.antigravity-manager.bak
• Verify accounts backup: ~/.config/opencode/antigravity-accounts.json.antigravity-manager.bak

1.2 Plugin Installation Scenarios

2. Sync Behavior Verification

2.1 Provider Creation

• provider.antigravity-manager created with correct structure
• npm: @ai-sdk/anthropic
• name: Antigravity Manager
• options.baseURL: ends with /v1 (auto-normalized)
• options.apiKey: matches proxy API key

2.2 Existing Providers Not Overwritten

• provider.google preserved (if exists)
• provider.anthropic preserved (if exists)
• Other providers untouched

2.3 Accounts Export File (v3 Structure)

{
  "version": 3,
  "accounts": [...],
  "activeIndex": 0,
  "activeIndexByFamily": {
    "claude": 0,
    "gemini": 0
  }
}

• File created at ~/.config/opencode/antigravity-accounts.json
• version field = 3
• activeIndex clamped to valid range
• activeIndexByFamily contains claude and gemini keys
• Disabled accounts excluded from export

3. Variants/Thinking Behavior Verification

3.1 Claude Thinking Models

opencode run "test" --model antigravity-manager/claude-sonnet-4-6-thinking --variant high

• --variant low → thinkingBudget: 8192
• --variant medium → thinkingBudget: 16384
• --variant high → thinkingBudget: 24576
• --variant max → thinkingBudget: 32768

3.2 Gemini 3 Pro Models

opencode run "test" --model antigravity-manager/gemini-3-pro-high --variant low

• --variant low → thinkingLevel: "low"
• --variant high → thinkingLevel: "high"

3.3 Gemini 3 Flash Models

• --variant minimal → thinkingLevel: "minimal"
• --variant low → thinkingLevel: "low"
• --variant medium → thinkingLevel: "medium"
• --variant high → thinkingLevel: "high"

3.4 Gemini 2.5 Flash Thinking

• --variant low → thinkingBudget: 8192
• --variant medium → thinkingBudget: 12288
• --variant high → thinkingBudget: 16384
• --variant max → thinkingBudget: 24576

4. Plugin Compatibility Verification

4.1 Plugin Model Unaffected

# If opencode-antigravity-auth plugin installed
opencode run "test" --model google/antigravity-claude-sonnet-4-6-thinking --variant max

• Plugin provider works independently
• Manager sync does not interfere with plugin accounts
• Both can coexist

5. Clear/Restore Verification

5.1 Clear Config

• Removes provider.antigravity-manager
• Optional: clears legacy entries from provider.google and provider.anthropic
• Preserves other providers

5.2 Restore Function

6. Pass/Fail Summary Table

7. Troubleshooting Notes

Issue: Sync fails with "Failed to get OpenCode config directory"

Cause: Cannot determine home directory
Fix: Ensure HOME (Unix) or USERPROFILE (Windows) env var is set

Issue: Variant not applied

Cause: Model ID mismatch or variant type not defined
Fix: Check model ID in catalog matches request; verify variant_type in build_model_catalog()

Issue: Backup not created

Cause: Backup file already exists (idempotent)
Fix: Delete existing .bak files manually if you need fresh backup

Issue: Accounts not exported

Cause: All accounts disabled or sync_accounts not checked
Fix: Enable at least one account; check "Sync accounts" option in UI

Issue: Plugin conflicts with manager provider

Cause: Both using same model IDs
Fix: Use different model IDs or disable one provider

Issue: Restore fails

Cause: Backup files missing or permissions
Check:

ls -la ~/.config/opencode/*.bak
