Agent Templates & Archetypes

This file provides:

Guidance for Standard Templates - How to find and create user-facing agents
Role-Based Contract Archetypes - Structured patterns for orchestrated multi-agent workflows

Choosing Between Template Types

<template_decision>

Use Standard Templates When

Agent responds directly to user (not delegated by another agent)
Agent has flexibility in how it operates and reports
Output format can vary by task or user preference
Agent operates independently without supervisor coordination

Examples: A code reviewer that runs when user asks, a documentation generator, a language expert.

Use Role-Based Contract Archetypes When

Agent is delegated to by another agent (orchestration pattern)
Strict DONE/BLOCKED signaling needed for workflow control
Work involves clear handoffs between multiple agents
Blocking is preferred over guessing when information is missing
Supervisor needs predictable status to decide next steps

Examples: A coder subagent in a supervisor-worker pattern, a researcher gathering context for an architect agent.

</template_decision>

Template Methodology

Standard Templates

Origin: Derived from existing agents in .claude/agents/ and common software engineering workflows.

How to Find: Read existing project agents to identify patterns that match your needs:

# Find all project agents
ls -la .claude/agents/

# Read agents to understand patterns
cat .claude/agents/*.md

Structure: Standard agents typically include:

Frontmatter with sensible defaults
Identity/role statement
Focus areas or competencies
Workflow steps
Output format (flexible, task-appropriate)
Quality standards

Creating from Scratch: Use the structure in Agent Schema Reference and adapt an existing similar agent as your starting point.

Role-Based Contract Archetypes

Origin: Based on the supervisor-worker delegation pattern where agents must signal completion status for workflow orchestration.

Structure: Uses {{placeholder}} syntax (double braces). Each archetype includes:

Frontmatter with skills: subagent-contract
Mission statement (single responsibility)
Scope (explicit do/don't boundaries)
Inputs specification
Operating rules
SOP (Standard Operating Procedure)
Output format with STATUS: DONE/BLOCKED signaling
Supervisor co-prompt template

Templating: Replace {{placeholder}} values. The DONE/BLOCKED signaling is mandatory; artifact structure is customizable per agent.

</methodology>

How to Use This File

Determine Category: Standard (user-facing) or Role-Based (orchestrated)?
For Standard Agents: Read existing agents in .claude/agents/ to find similar patterns
For Role-Based Agents: Use the archetypes below as starting points
Adapt Section-by-Section: Preserve structure, update content
Customize: Modify tool access, skills, output format for the use case

Agent Location Conventions

Project Agents: .claude/agents/ in repository root User Agents: ~/.claude/agents/ in home directory Plugin Agents: {plugin-root}/agents/ in plugin directory

When creating agents, choose the appropriate location based on scope:

Project agents: Specific to one codebase, shared with team via git
User agents: Personal agents used across all projects
Plugin agents: Part of a plugin, installed with the plugin

Finding Standard Agent Patterns

For user-facing agents, look for similar agents in the project's .claude/agents/ directory:

User Need	Look For
"Review code for X"	Agents with `tools: Read, Grep, Glob` and review in description
"Understand the architecture"	Read-only analyzers with `permissionMode: dontAsk`
"Generate documentation"	Agents with `permissionMode: acceptEdits` and doc-related names
"Write tests for"	Agents loading testing-related skills
"Fix this bug"	Agents with full tool access and `model: opus`
"Refactor this code"	Agents with edit permissions
"Research before implementing"	Agents with `permissionMode: plan` or `dontAsk`
"Plan how to build"	Planning agents with read-only access
"Check before I commit"	Validator agents that run commands
"Expert in {language}"	Agents loading language-specific skills
"Expert in {framework}"	Agents loading framework-specific skills

If no similar agent exists, build from scratch using Agent Schema Reference.

Role-Based Contract Archetypes

These templates follow a structured contract pattern with standardized inputs/outputs. All agents using these templates should load the subagent-contract skill for consistent behavior.

Complete Agent Frontmatter Reference

Required Fields

Field	Type	Required	Description	Example
`name`	string	Yes	Unique identifier (lowercase, hyphens, max 64)	`python-reviewer`
`description`	string	Yes	Trigger keywords + purpose (max 1024 chars)	`"Review Python code for quality issues"`

Optional Fields

Field	Type	Default	Valid Values	Description
`model`	string	`inherit`	`sonnet`, `opus`, `haiku`, `inherit`	Claude model to use
`tools`	string	(all tools)	Comma-separated: `Read, Grep, Glob, Bash, Edit, Write`	Tools available to agent
`disallowedTools`	string	(none)	Comma-separated tool names	Tools explicitly forbidden
`permissionMode`	string	(inherit)	`dontAsk`, `plan`, `acceptEdits`, `acceptAll`	Permission behavior
`skills`	string	(none)	Comma-separated skill names	Skills to load
`color`	string	(none)	`cyan`, `yellow`, `orange`, `green`, `red`	Visual distinction in UI
`hooks`	N/A	N/A	NOT VALID IN AGENT FRONTMATTER (use plugin hooks.json)	Hooks are plugin-level, not agent-level

CRITICAL: The hooks field is NOT valid in agent frontmatter. Hooks are configured at the plugin or project level in hooks/hooks.json or .claude-plugin/plugin.json.

Selecting Role-Based Archetypes

User Need	Recommended Role Archetype
"Research X before we decide"	Researcher
"Design the architecture for"	Planner / Architect
"Implement this feature"	Coder
"Create an agent/skill/template"	Creator
"Write tests for"	Tester
"Review this code/PR"	Reviewer
"Set up CI/CD for"	DevOps / SRE
"Audit compliance/drift"	Auditor
"Gather context for task"	Context Gatherer
"Optimize/improve X"	Optimizer
"Expert in {domain}"	Domain Expert

All role-based archetypes should include skills: subagent-contract to enforce consistent contract behavior.

Best Practices from Existing Agents

<best_practices>

Description with Embedded Examples

For complex agents, include <example> blocks in the description showing invocation:

description: 'Review Python code for issues. Use for code quality audits. <examples><example>user: "Review my authentication code for security issues" assistant: "I will use the python-reviewer agent for security-focused review."</example></examples>'

Identity Section

Start the agent body with a clear identity statement using XML tags:

<identity>
You assess {{artifacts}} by:
- Reading and analyzing ALL relevant files
- Validating against {{standard}}
- Producing actionable recommendations
</identity>

Critical Restrictions

For agents with strict boundaries, include explicit restrictions:

## Critical Restrictions

**YOU MUST NEVER:**
- Edit files outside the designated location
- Make assumptions about missing information
- Proceed without required inputs

**YOU MAY ONLY:**
- Read files for research
- Edit the specific output file
- Return findings in specified format

Important Output Note

For subagents, remind that output must be returned (caller can't see execution):

## Important Output Note

IMPORTANT: Neither the caller nor the user can see your execution unless you return it
as your response. Your complete output must be returned as your final response.

Self-Verification Checklist

Include a checklist for quality self-assessment:

## Self-Verification

Before completing, verify:
- [ ] Did I address all acceptance criteria?
- [ ] Did I cite evidence for findings?
- [ ] Did I follow the specified output format?
- [ ] Would my output be actionable by the supervisor?

Example Invocations

Show how to call the agent with Task():

## Example Invocations

\`\`\`text
Task(
  agent="my-agent",
  prompt="Specific task with context and requirements"
)
\`\`\`

Color Field for Visual Distinction

Use color in frontmatter for agents that benefit from visual identification:

Color	Use Case
`cyan`	Analysis, research
`yellow`	Optimization, warnings
`orange`	Audits, reviews
`green`	Validation, success
`red`	Errors, security

Pragmatic Review Guidance

For review agents, include "keep it real" guidance:

## Keep It Real

Consider the "realness" of issues:
- Dev tooling doesn't need production-grade security
- Non-critical paths can have simpler error handling
- Weigh fix complexity against actual risk
