Custom Agent Creator
Overview
Subagents are specialized AI assistants defined as Markdown files with YAML frontmatter. Each subagent runs in its own context window with a custom system prompt, specific tool access, and independent permissions. When a task matches a subagent’s description, the parent conversation delegates to it automatically, preserving main context while enforcing constraints.
When to use: Isolating high-volume operations (tests, logs), enforcing read-only access for reviewers, routing simple tasks to cheaper models, running parallel research, creating reusable team workflows.
When NOT to use: Tasks requiring frequent back-and-forth, quick targeted changes, workflows needing nested delegation (subagents cannot spawn subagents), latency-sensitive operations where fresh context gathering is costly.
Quick Reference
| Pattern | Configuration | Key Points |
|---|---|---|
| File location (project) | .claude/agents/name.md |
Shared via version control, priority 2 |
| File location (user) | ~/.claude/agents/name.md |
Available across all projects, priority 3 |
| Required fields | name, description |
Only two fields are mandatory |
| Tool restriction | tools: Read, Grep, Glob |
Allowlist; inherits all if omitted |
| Tool denial | disallowedTools: Write, Edit |
Denylist; removed from inherited set |
| Model selection | model: haiku |
Options: sonnet, opus, haiku, inherit (default) |
| Permission mode | permissionMode: dontAsk |
Controls permission prompt behavior |
| Skill preloading | skills: [auth, api-patterns] |
Injected at startup; no inheritance from parent |
| Lifecycle hooks | hooks: { PreToolUse: [...] } |
Validate or block tool usage conditionally |
| CLI-defined agent | claude --agents '{...}' |
Session-only, highest priority, JSON format |
| Interactive creation | /agents command |
Guided setup with Claude generation |
| Proactive triggers | "Use proactively after..." |
Include in description for auto-delegation |
Common Mistakes
| Mistake | Correct Pattern |
|---|---|
| Using opus for simple checklist reviews | Use haiku for read-only reviews and style checks |
| Omitting output format in system prompt | Include structured output template for consistent results |
| Listing tools explicitly when all are needed | Omit tools field to inherit all tools including MCP |
| Expecting skills from parent conversation | Explicitly list skills in the skills field |
| Generic description without triggers | Include specific trigger phrases like “Use proactively when…” |
| Giving a single agent too many responsibilities | Design focused agents with one clear purpose each |
Using bypassPermissions without caution |
Prefer acceptEdits or dontAsk for safer automation |
| Creating deeply nested agent workflows | Chain subagents from main conversation; nesting is not supported |
Delegation
- Agent pattern discovery: Use
Exploreagent to find existing agents in.claude/agents/ - Interactive creation: Use
/agentscommand for guided setup with Claude generation - Code review of agent files: Use
Taskagent to validate system prompts and configuration
