agent-types

agent-types is an agent for Claude Code from daffy0208/ai-dev-standards. It costs 0 tokens per session (3,597 once invoked), scanned A, original, MIT.

A catalogue of the agent types available in Claude Code and the ai-dev-standards repository. It explains the difference between built-in agents and skill-based agents, including their purposes and typical tasks.

In plain words
What is it for?
Use it to compare agents for bug fixes, feature work, refactoring, code review preparation, codebase exploration, research, and other development tasks.
Why use it?
It gives developers a map of the available choices before they decide which agent to use. This avoids treating every agent as interchangeable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-types scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Agent Types: Complete Taxonomy

Comprehensive classification of all agent types available in Claude Code and the ai-dev-standards repository.


Overview

Total Agent Types: 10

  • 4 Claude Code Built-in Agents - Native CLI agents
  • 6 Skill-Based Agents - Skills that function as autonomous agents

1. Claude Code Built-in Agents (4)

1.1 General-Purpose Agent

Type: Default, Multi-Purpose Status: Active Invocation: Default mode

Purpose: Comprehensive development agent for most tasks including code search, analysis, editing, and multi-step research.

Core Capabilities:

  • Multi-file analysis and editing
  • Complex codebase exploration
  • System architecture understanding
  • Multi-step research tasks
  • File operations (read, write, edit)
  • Pattern recognition and matching

Best For:

  • Bug investigation and fixes
  • Feature implementation
  • Refactoring
  • Code review preparation
  • Ongoing development work

Performance:

  • Speed: Variable (depends on task)
  • Depth: High
  • Memory: Handles large files efficiently

Integration:

  • Can invoke any of 59 skills
  • Access to 36 MCP servers
  • Works with all tools and components

Documentation: general-purpose.md


1.2 Explore Agent

Type: Codebase Discovery Status: Active Invocation: Via explore mode

Purpose: Fast, configurable codebase exploration with three thoroughness levels.

Modes:

  1. Quick - Fast overview (seconds to minutes)
  2. Medium - Balanced exploration (5-15 minutes) [Default]
  3. Very Thorough - Deep analysis (30+ minutes)

Core Capabilities:

  • Initial repository assessment
  • Architecture understanding
  • Pattern discovery
  • Rapid familiarization
  • Dependency mapping

Best For:

  • New codebase onboarding
  • Pre-refactoring analysis
  • Security audit preparation
  • Architecture documentation
  • Migration planning

Performance:

  • Speed: Configurable (Quick/Medium/Very Thorough)
  • Depth: Configurable by mode
  • Memory: Scales with thoroughness level

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agent-types is an agent published in the GitHub repository daffy0208/ai-dev-standards (36 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,597 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
