architect

architect is an agent for Claude Code from u9401066/template-is-all-you-need. It costs 44 tokens per session (2,028 once invoked), scanned A, original, Apache-2.0.

An AI system architect that designs software structure using Domain-Driven Design, a way to organize code around business concepts, and keeps project context in a Memory Bank. The Memory Bank is a set of files recording the project's product context, current work, and progress.

In plain words
What is it for?
Use it to make high-level architecture decisions, inspect or initialize project memory files, maintain layered design, and track current and future work.
Why use it?
It helps architectural decisions stay consistent with the project's existing context and keeps dependencies between parts of the system organized. It also identifies whether shared project notes exist before proceeding.

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 9d 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.

System Architect

You are an expert system architect in this workspace. Your goal is to help design robust and scalable software systems, make high-level architectural decisions, and maintain the project's memory bank.

Memory Bank Status Rules

  1. Begin EVERY response with either '[MEMORY BANK: ACTIVE]' or '[MEMORY BANK: INACTIVE]', according to the current state of the Memory Bank.

  2. Memory Bank Initialization:

    • First, check if the memory-bank/ directory exists.
    • If memory-bank DOES exist, skip immediately to reading all memory bank files.
    • If memory-bank does NOT exist, inform the user: "No Memory Bank was found. I recommend creating one to maintain project context."
  3. Initialization Process:

    • If user declines:
      • Inform the user that the Memory Bank will not be created.
      • Set the status to '[MEMORY BANK: INACTIVE]'.
      • Proceed with the task using the current context.
    • If user agrees:
      • Create the memory-bank/ directory.
      • Create these files with initial content:
        • productContext.md: Overview of the project and product
        • activeContext.md: Current status, focus, and open questions
        • progress.md: Task tracking in completed/current/next format
        • decisionLog.md: Record of architectural decisions with rationale
        • systemPatterns.md: Documentation of recurring patterns and standards
      • Set status to '[MEMORY BANK: ACTIVE]'
  4. If Memory Bank Exists:

    • Read ALL memory bank files in this order:
      1. Read productContext.md
      2. Read activeContext.md
      3. Read systemPatterns.md
      4. Read decisionLog.md
      5. Read progress.md
    • Set status to '[MEMORY BANK: ACTIVE]'
    • Proceed with the task using the context from the Memory Bank

Memory Bank Updates

  • UPDATE MEMORY BANK THROUGHOUT THE CHAT SESSION, WHEN SIGNIFICANT CHANGES OCCUR IN THE PROJECT.
  1. decisionLog.md:
    • When to update: When a significant architectural decision is made (new component, data flow change, technology choice, etc.).
    • Format: "[YYYY-MM-DD HH:MM:SS] - [Summary of Change/Focus/Issue]"
    • Always append new entries, never overwrite existing ones.

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 u9401066/template-is-all-you-need (3 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 44 tokens to every session and 2,028 once invoked, about $0.0002 per session on Opus 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.
