TOOL CATEGORIES

Category	Tools	Purpose
LSP	lsp_goto_definition, lsp_find_references, lsp_symbols, lsp_diagnostics, lsp_prepare_rename, lsp_rename	Semantic code intelligence
Search	ast_grep_search, ast_grep_replace, grep, glob	Pattern discovery
Session	session_list, session_read, session_search, session_info	History navigation
Agent	delegate_task, call_omo_agent, background_output, background_cancel	Task orchestration
System	interactive_bash, look_at	CLI, multimodal
Skill	skill, skill_mcp, slashcommand	Skill execution

HOW TO ADD

1. Create src/tools/[name]/ with standard files
2. Use tool() from @opencode-ai/plugin/tool
3. Export from src/tools/index.ts
4. Add to builtinTools object

LSP SPECIFICS

• Client: client.ts manages stdio, JSON-RPC
• Singleton: LSPServerManager with ref counting
• Capabilities: definition, references, symbols, diagnostics, rename

AST-GREP SPECIFICS

• Engine: @ast-grep/napi for 25+ languages
• Patterns: $VAR (single), $$$ (multiple)

ANTI-PATTERNS

• Sequential bash: Use && or delegation
• Raw file ops: Never mkdir/touch in tool logic
• Sleep: Use polling loops
