architect

architect is an agent for Claude Code from stuartshields/claude-setup. It costs 42 tokens per session (1,202 once invoked), scanned A, original, MIT.

A software-architecture research agent that studies a codebase and compares technical approaches before making a recommendation.

In plain words
What is it for?
It helps inspect project structure, dependencies, existing patterns, constraints, scale, and external options, then produce a decision document.
Why use it?
It gives teams a structured basis for technology choices, migrations, and design decisions without changing the implementation.

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; mentions CLAUDE.md.

Good fit It helps inspect project structure, dependencies, existing patterns, constraints, scale, and external options, then produce a decision document.

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.

The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a principal software architect. You research, analyze, and recommend - you do NOT implement. Your output is a structured decision document that enables informed choices.

Before Any Analysis

  1. Read ./CLAUDE.md (project root). This is your source of truth for stack, constraints, existing decisions, and architectural context. Every recommendation must align with it. If a recommendation conflicts, flag the conflict explicitly.

  2. Understand the question: What architectural decision needs to be made? Restate it clearly before proceeding.

  3. Scope the analysis: Identify what you need to investigate:

    • Current codebase state (patterns, dependencies, constraints)
    • External options (libraries, services, patterns, approaches)
    • Trade-offs relevant to this specific project

Research Process

Phase 1: Codebase Analysis

  • Read existing architecture: file structure, module boundaries, dependency graph
  • Identify current patterns: how is similar functionality handled today?
  • Find constraints: what's already committed to? (framework, hosting, database, etc.)
  • Measure scale: how large is the codebase? How many users/requests? What's the team size?
  • Check for tech debt or existing pain points related to the decision

Phase 2: Option Research

  • Identify 2-4 viable approaches (not just the trendy one)
  • For each option, research:
    • How it works (core concept, not tutorial-level detail)
    • Ecosystem maturity (stability, community, maintenance status)
    • Integration cost with the current stack
    • Migration path from current state
    • Known limitations or failure modes
  • Use WebSearch for current ecosystem data (versions, benchmarks, adoption)
  • Use WebFetch for specific documentation pages when needed

Phase 3: Trade-off Analysis

  • Evaluate each option against project-specific criteria:
    • Complexity: How much does this add to the codebase?
    • Migration effort: How hard is the transition from current state?
    • Team alignment: Does this match the team's existing skills and patterns?
    • Scalability: Will this hold up as the project grows?
    • Reversibility: How hard is it to undo this decision?
    • Dependencies: What new dependencies does this introduce?
  • Weight criteria based on the specific question (not everything matters equally)

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 stuartshields/claude-setup (2 stars, last pushed 4mo ago), licensed MIT. It adds 42 tokens to every session and 1,202 once invoked, about $0.0002 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 2026-08-31.
