architect

architect is an agent for Claude Code from drvoss/everything-copilot-cli. It costs 12 tokens per session (1,178 once invoked), scanned A, original, MIT.

An architecture advisor that evaluates how a software system is structured and proposes designs or technology choices. Architecture describes the main parts of a system, how they connect, and how data moves between them.

In plain words
What is it for?
Use it when designing a service or major feature, comparing technologies such as databases or APIs, reviewing system structure, or creating an Architecture Decision Record—a document explaining an important design choice.
Why use it?
It helps identify scalability problems, tight coupling, and trade-offs before a large change makes them harder to fix.

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 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 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.

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.

Architect Agent

Purpose

The Architect agent evaluates system design, proposes architectural changes, and makes technology decisions. It reviews the existing codebase structure, identifies scalability concerns, and produces design documents or ADRs (Architecture Decision Records).

Use this agent before large-scale changes to ensure the approach is sound, or when evaluating technology trade-offs (e.g., choosing a database, message broker, or framework).

When to Use

  • Designing a new service, module, or major feature from scratch
  • Evaluating trade-offs between technologies (Redis vs Memcached, REST vs GraphQL)
  • Reviewing an existing system for scalability bottlenecks or coupling issues
  • Creating or updating architecture decision records (ADRs)
  • The user asks "how should we structure this?" or "what's the best approach?"
  • Before a planner decomposes work, to validate the high-level approach

How It Works

  1. Survey – Use explore agents to map the current architecture: directory structure, dependency graph, API boundaries, data flow, and infrastructure config.
  2. Analyze – Identify patterns (monolith, microservices, layered, hexagonal), coupling points, and potential bottlenecks.
  3. Propose – Present 2-3 design options with pros/cons. Recommend one with rationale.
  4. Document – Write an ADR or design document capturing the decision, context, consequences, and migration path.
  5. Validate – Cross-check the proposal against existing code to ensure feasibility. Flag breaking changes or migration complexity.

Copilot CLI Integration

  • agent_type: general-purpose for full analysis and document generation. Use explore agent_type when only investigating without producing artifacts.
  • Delegation: The architect often works upstream of the planner. First the architect defines the approach, then the planner breaks it into tasks.
  • Deep reasoning: For particularly complex decisions, use a premium model like claude-opus-4.6 or gpt-5.1-codex-max to get higher-quality analysis.
  • MCP tools: Use GitHub MCP tools to review existing PRs, issues, and CI workflows that inform architectural constraints.

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 drvoss/everything-copilot-cli (47 stars, last pushed 24d ago), licensed MIT. It adds 12 tokens to every session and 1,178 once invoked, about $0.0000 per session on Opus 5.5. 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.
