Subagent Toolset - Constrained Subagent Tool Sets

Purpose

When spawning a sub-agent, select the appropriate tool subset based on task type and add it to the task prompt to constrain its behavior.

Tool Subsets

Explore

For information gathering, code reading, file analysis.

• read_file: Read file contents
• glob_search: Path pattern search
• grep_search: Content search
• WebFetch: Fetch web page content
• WebSearch: Web search
• Skill: Invoke other skills
• StructuredOutput: Structured output

Forbidden: exec, sessions_spawn, edit, write

Plan

For task breakdown, planning, scheme design.

• read_file: Read files
• glob_search: Path search
• grep_search: Content search
• WebFetch: Fetch reference material
• TodoWrite: Write task list
• SendUserMessage: Send messages
• StructuredOutput: Structured output

Forbidden: exec, sessions_spawn, edit, write

Verification

For testing, verification, result confirmation.

• bash: Execute commands (read-only verification commands only)
• read_file: Read files
• glob_search: Path search
• grep_search: Content search
• WebFetch: Fetch reference material
• TodoWrite: Record results
• StructuredOutput: Structured output
• PowerShell: Windows commands

Forbidden: sessions_spawn, edit (dangerous write operations)

Coding

For code writing, debugging, fixing.

• read_file: Read files
• write_file: Write files
• edit_file: Edit files
• glob_search: Path search
• grep_search: Content search
• bash: Execute commands for verification
• TodoWrite: Task tracking
• StructuredOutput: Structured output
• WebFetch: Fetch reference material

Full tool access (high privilege)

Secretary

For document organization, summarization, report generation.

• read_file: Read files
• glob_search: Path search
• TodoWrite: Write task list
• SendUserMessage: Send messages
• StructuredOutput: Structured output

Forbidden: exec, sessions_spawn, edit, write, glob_search, grep_search

Usage

When spawning a sub-agent, read the corresponding tool subset from this skill and prepend it to the task prompt:

You are an Explore-type sub-agent.
You may only use the following tools: read_file, glob_search, grep_search, WebFetch, WebSearch, Skill
Forbidden: exec, sessions_spawn, edit, write

[Your task follows...]

Notes

• Tool subsets are soft constraints (LLM compliance), not hard restrictions
• For dangerous operations (file deletion, config modification), explicit prohibition is required
• High-privilege tasks (Coding type) should be used with caution
