src/tools/ — 12–31 Native Tools Across 13 Tool Directories (+ shared utilities)

Generated: 2026-05-15

OVERVIEW

Tools registered via createToolRegistry() in src/plugin/. Native tools are factory-based (createXXXTool) except interactive_bash (ToolDefinition). LSP and AST-grep tools are no longer native src/tools/ implementations; they are served by Tier-1 built-in MCPs lsp and ast_grep and keep the same exposed names (lsp_diagnostics, ast_grep_search, etc.).

TOOL CATALOG

Always On (12 native tools)

Group	Tools
Search (2)	grep, glob
Sessions (4)	session_list, session_read, session_search, session_info
Background tasks (2)	background_output, background_cancel
Delegation (2)	task (delegate, full skill+category support), call_omo_agent (named agent only: explore, librarian)
Skills/MCP (2)	skill (load skill or invoke command), skill_mcp (call skill-embedded MCP tool/resource/prompt)

LSP and AST-grep tools are now provided by built-in MCP servers lsp and ast_grep (Tier-1 stdio), backed by packages/lsp-tools-mcp/ and packages/ast-grep-mcp/. OpenCode-compatible aliases remain available (lsp_status, lsp_diagnostics, lsp_goto_definition, lsp_find_references, lsp_symbols, lsp_prepare_rename, lsp_rename, ast_grep_search, ast_grep_replace).

Conditional (up to +19 native tools)

Tool(s)	Gate	Source
look_at	not in disabled_agents for multimodal-looker	look-at/
interactive_bash	isInteractiveBashEnabled(config) (tmux config)	interactive-bash/
task_create, task_get, task_list, task_update	experimental.task_system	task/
edit (hashline-edit)	hashline_edit: true	hashline-edit/
12 team_* tools	team_mode.enabled: true	../features/team-mode/tools/

12 team_* Tools (when team_mode enabled)

Tool	Purpose
team_create	Spawn team + member sessions from a TeamSpec (named or inline)
team_delete	Tear down — removes mailbox, tasklist, worktrees, optional tmux layout
team_shutdown_request	Member or lead requests its own shutdown
team_approve_shutdown	Lead acks a pending shutdown
team_reject_shutdown	Lead rejects a shutdown with reason
team_send_message	Async message to specific member or * broadcast
team_task_create	Create task on shared list
team_task_list	List tasks (filter by status, owner)
team_task_update	Claim/complete/delete (atomic file lock)
team_task_get	Fetch single task
team_status	Full team run status (members, tasks, mailbox)
team_list	List declared + active teams

DELEGATION CATEGORIES (built-in 8)

task (delegate) selects model by category. Default category models live in provider-specific files under src/tools/delegate-task/ and aggregate via BUILTIN_CATEGORIES in builtin-categories.ts. Authoritative fallback chains in src/shared/model-requirements.ts CATEGORY_MODEL_REQUIREMENTS.

Category	Default Model	Source File	Domain
visual-engineering	google/gemini-3.1-pro (variant: high)	google-categories.ts	Frontend, UI/UX
ultrabrain	openai/gpt-5.5 (variant: xhigh)	openai-categories.ts	Hard logic / heavy reasoning
deep	openai/gpt-5.5 (variant: medium)	openai-categories.ts	Autonomous multi-step problem-solving
artistry	google/gemini-3.1-pro (variant: high)	google-categories.ts	Creative / unconventional approaches
quick	openai/gpt-5.4-mini	openai-categories.ts	Trivial single-file changes
unspecified-low	anthropic/claude-sonnet-4-6	anthropic-categories.ts	Moderate effort fallback
unspecified-high	anthropic/claude-opus-4-7 (variant: max)	anthropic-categories.ts	High effort fallback
writing	kimi-for-coding/k2p5 (default) → gemini-3-flash (first fallback)	kimi-categories.ts	Documentation, prose

User-defined categories declared in categories: { ... } config override and extend this set.

ADDING A NEW TOOL

1. Create src/tools/{name}/index.ts with factory createXXXTool
2. Add types.ts for parameter Zod schemas
3. Add tools.ts (or single index.ts) for implementation
4. Export factory from src/tools/index.ts
5. Register in src/plugin/tool-registry.ts:
   • Always-on: spread into allTools directly
   • Conditional: build a Record<string, ToolDefinition> and gate-spread
6. If the tool needs disabling, ensure it appears in filterDisabledTools allow-list (its name will be matched against disabled_tools)
