## WHEN TO USE
| Task | Utility |
|------|---------|
| Debugging/Auditing | `log(message, data)` in `logger.ts` |
| Limit agent context | `dynamicTruncate(ctx, sessionId, output)` |
| Parse rule meta | `parseFrontmatter(content)` |
| Load user configs | `parseJsonc(text)` or `readJsoncFile(path)` |
| Restrict tools | `createAgentToolAllowlist(tools)` |
| Resolve app paths | `getOpenCodeConfigDir()` or `getClaudeConfigDir()` |
| Update legacy config | `migrateConfigFile(path, rawConfig)` |
| Debug logging | `log(message, data)` in `logger.ts` |
| Limit context | `dynamicTruncate(ctx, sessionId, output)` |
| Parse frontmatter | `parseFrontmatter(content)` |
| Load JSONC config | `parseJsonc(text)` or `readJsoncFile(path)` |
| Restrict agent tools | `createAgentToolAllowlist(tools)` |
| Resolve paths | `getOpenCodeConfigDir()`, `getClaudeConfigDir()` |
| Migrate config | `migrateConfigFile(path, rawConfig)` |
| Compare versions | `isOpenCodeVersionAtLeast("1.1.0")` |
## KEY PATTERNS
## CRITICAL PATTERNS
```typescript
// Truncate large output based on 50% remaining context window
const { result } = await dynamicTruncate(ctx, sessionID, largeBuffer);
// Token-aware truncation
const { result } = await dynamicTruncate(ctx, sessionID, largeBuffer)
// Safe config loading with comment/trailing comma support
const settings = readJsoncFile<Settings>(configPath);
// JSONC config loading
const settings = readJsoncFile<Settings>(configPath)
// Version-gated logic for OpenCode 1.1.0+
if (isOpenCodeVersionAtLeast("1.1.0")) { /* ... */ }
// Version-gated features
if (isOpenCodeVersionAtLeast("1.1.0")) { /* new feature */ }
// Permission normalization for agent tools
const permissions = migrateToolsToPermission(legacyTools);
// Tool permission normalization
const permissions = migrateToolsToPermission(legacyTools)
```
## ANTI-PATTERNS
- Raw `JSON.parse` for configs (use `jsonc-parser.ts`)
- Hardcoded `~/.claude` (use `claude-config-dir.ts`)
- `console.log` for background agents (use `logger.ts`)
- Unbounded tool output (always use `dynamic-truncator.ts`)
- Manual version parsing (use `opencode-version.ts`)
- **Raw JSON.parse**: Use `jsonc-parser.ts` for config files
- **Hardcoded paths**: Use `*-config-dir.ts` utilities
- **console.log**: Use `logger.ts` for background agents
- **Unbounded output**: Always use `dynamic-truncator.ts`
- **Manual version parse**: Use `opencode-version.ts`
