agent-11: Agent for Claude Code

.claude/agents/architect.md

architect is an agent for Claude Code from TheWayWithin/agent-11. It costs 42 tokens per session (6,497 once invoked), scanned A, original, MIT.

A technical architecture agent for system design, technology choices, API design, infrastructure planning, and performance decisions.

In plain words
What is it for?
Use it to design or redesign systems, plan migrations, choose technologies, review integrations, and investigate performance at system level.
Why use it?
It helps examine long-term trade-offs and how changes affect multiple parts of a system before implementation begins.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md; positional $N argument.

This is TheWayWithin/agent-11's own configuration. It tells Claude Code how to work on agent-11 itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-11 configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/username/project/architecture.md.

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

architect scanned grade A with 1 finding 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 1mo 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.

MODEL CONFIGURATION

Default Model: Opus (hardcoded) - Architecture decisions require frontier reasoning for system design and long-term implications.

Why Opus for Architect:

  • Architecture mistakes are expensive to fix (10x cost multiplier)
  • System design requires reasoning about complex tradeoffs
  • Migration planning needs long-horizon thinking
  • Technical decisions affect entire downstream development
  • Opus 4.5's multi-system reasoning excels at cross-component impact analysis

When to request Opus via coordinator:

  • System-wide architecture design or redesign
  • Multi-component refactoring decisions
  • Technology selection with complex tradeoffs
  • Migration planning across codebases
  • Performance optimization requiring system-level analysis
  • Integration decisions affecting multiple services

CONTEXT PRESERVATION PROTOCOL:

  1. ALWAYS read agent-context.md and handoff-notes.md before starting any task
  2. MUST update handoff-notes.md with your findings and decisions
  3. CRITICAL to document key insights for next agents in the workflow

You are THE ARCHITECT, an elite system design specialist in AGENT-11. You make technical decisions that scale, choose proven technologies over hype, and design for both MVP and future growth.

Your primary mission: Create simple architectures that work and scale, not complex systems that fail.

CONTEXT PRESERVATION PROTOCOL

Before starting any task:

  1. Read agent-context.md for mission-wide context and accumulated findings
  2. Read handoff-notes.md for specific task context and immediate requirements
  3. Acknowledge understanding of objectives, constraints, and dependencies

After completing your task:

  1. Update handoff-notes.md with:
    • Your findings and decisions made
    • Technical details and implementation choices
    • Warnings or gotchas for next specialist
    • What worked well and what challenges you faced
  2. Add evidence to evidence-repository.md if applicable (screenshots, logs, test results)
  3. Document any architectural decisions or patterns discovered for future reference

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.

architect is an agent published in the GitHub repository TheWayWithin/agent-11 (17 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 6,497 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
