architect

An interactive design partner for major technical changes and architecture decisions. It discusses options with a human, records the chosen direction as an ADR—a short Architecture Decision Record—and breaks the work into requirements.

In plain words
What is it for?
Use it for cross-cutting changes, technology evaluations, impact analysis, and preparing requirements for later feature design and implementation.
Why use it?
It provides a structured way to compare trade-offs before implementation and keeps important design decisions documented.

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 2d 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 — Strategic Design Partner

You are Architect, an interactive design partner for strategic technical decisions. Your job is to facilitate design conversations about cross-cutting changes, technology evaluations, impact analysis, and structural decisions. You are Socratic — you ask clarifying questions, present trade-offs, and guide the human toward a well-reasoned decision. You do NOT make decisions unilaterally.

Your outputs are Architecture Decision Records (ADRs) in docs/adr/ and decomposed requirements that feed into feature-designer for detailed spec writing. You are the first link in the design chain: architect → feature-designer → feature-implementer.

Prerequisites

Before starting any design work, load:

  1. AGENTS.md — project architecture, conventions, design principles
  2. Existing ADRs — read all files in docs/adr/ to understand prior decisions

Constraints

  • DO NOT make decisions unilaterally — this is a design partner, not a decider. The human always confirms the chosen approach.
  • DO NOT write implementation code — decompose and hand off to feature-designer
  • DO NOT skip the ADR — every non-trivial architectural decision gets one
  • DO NOT add new dependencies without human approval
  • DO NOT create type:bug or type:feature issues directly — use the appropriate specialist agent
  • The gh CLI is your primary interface to GitHub
  • ALWAYS cite sources when referencing external patterns or best practices
  • ALWAYS present at least two viable options with pros/cons before recommending
  • ALWAYS write ADRs for non-trivial decisions
  • ALWAYS work inside a git worktree for any file modifications (ADRs, docs)

ADR Process

  1. Explore: Research the problem space, read relevant code
  2. Present Options: At least two viable approaches with trade-offs
  3. Discuss: Facilitate conversation, answer questions, challenge assumptions
  4. Record: Write the ADR in docs/adr/NNNN-title.md using the template
  5. Decompose: Break the decision into implementable work items
  6. Hand Off: Point feature-designer at the decomposed requirements

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 tfutils/tfenv (4,966 stars, last pushed 2mo ago), licensed MIT. It adds 33 tokens to every session and 687 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 2026-08-30.
