## WHEN TO USE
| Task | Utility |
|------|---------|
| Find ~/.claude | `getClaudeConfigDir()` |
| Find ~/.config/opencode | `getOpenCodeConfigDir()` |
| Merge configs | `deepMerge(base, override)` |
| Parse user files | `parseJsonc()` |
| Check hook enabled | `isHookDisabled(name, list)` |
| Truncate output | `dynamicTruncate(text, budget)` |
| Resolve @file | `resolveFileReferencesInText()` |
| Execute shell | `resolveCommandsInText()` |
| Legacy names | `migrateLegacyAgentNames()` |
| Version check | `isOpenCodeVersionAtLeast(version)` |
| Map permissions | `normalizePermission()` |
| Track session | `SessionCursor` |
| 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)` |
## CRITICAL PATTERNS
```typescript
// Dynamic truncation with context budget
const output = dynamicTruncate(result, remainingTokens, 0.5)
// Truncate large output based on 50% remaining context window
const { result } = await dynamicTruncate(ctx, sessionID, largeBuffer);
// Config resolution priority
const final = deepMerge(deepMerge(defaults, userConfig), projectConfig)
// Safe config loading with comment/trailing comma support
const settings = readJsoncFile<Settings>(configPath);
// Safe JSONC parsing for user-edited files
const { config, error } = parseJsoncSafe(content)
// Version-gated logic for OpenCode 1.1.0+
if (isOpenCodeVersionAtLeast("1.1.0")) { /* ... */ }
// Version-gated features
if (isOpenCodeVersionAtLeast('1.0.150')) { /* ... */ }
// Permission normalization for agent tools
const permissions = migrateToolsToPermission(legacyTools);
```
## ANTI-PATTERNS
- Hardcoding paths (use `getClaudeConfigDir`, `getOpenCodeConfigDir`)
- Using `JSON.parse` for user configs (always use `parseJsonc`)
- Ignoring output size (large tool outputs MUST use `dynamicTruncate`)
- Manual version parsing (use `opencode-version.ts` utilities)
- Raw permission checks (use `permission-compat.ts`)
- 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`)
