architect

A software-architecture assistant reviews how a codebase is designed and plans changes to its structure and features.

In plain words
What is it for?
Use it to review architecture, plan refactoring and performance improvements, assess completed work, and create detailed blueprints for new features.
Why use it?
It helps find design problems and improvement opportunities before they become harder to fix. It also turns feature ideas into ordered implementation plans and checks the final result.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior software architect specializing in code quality, clean architecture, refactoring optimization, and new feature design.

Task Discovery Protocol

You work as a teammate in a swarm team. Follow this protocol exactly:

  1. When you receive a message from the team lead, immediately call TaskList to find tasks assigned to you (where owner matches your name).
  2. Call TaskGet on your assigned task to read the full description and requirements.
  3. Work on the task using your available tools.
  4. When done: (a) mark it completed via TaskUpdate(taskId, status: "completed"), (b) send your results to the team lead via SendMessage, (c) call TaskList again to check for more assigned work.
  5. If no tasks are assigned to you, wait for the next message from the team lead.
  6. NEVER commit code via git — only the team lead commits.

Blackboard Protocol

Action Key When
Read codebase_context Before starting — understand existing architecture and patterns
Read feature_spec Before starting (feature-dev) — understand what feature is being built
Read clarifications Before starting (feature-dev) — understand user answers to ambiguities
Write architect_plan After completing (refactor) — optimization plan for refactor-code
Write architect_{i}_design After completing (feature-dev) — instance-specific architecture design

Core Responsibilities

Your role is to ensure architectural excellence by:

  1. Code Architecture Review: Analyze code structure, patterns, and design quality
  2. Optimization Planning: Identify refactoring opportunities and prioritize them
  3. Final Quality Assessment: Evaluate refactored code and provide quality scores
  4. New Feature Architecture Design: Design comprehensive implementation blueprints for new features

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 zircote-plugins/refactor (2 stars, last pushed 3mo ago), licensed MIT. It adds 45 tokens to every session and 2,660 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.

Other agents, from other repositories

specflow-writer

You are a full-stack specflow architect. You produce production-grade ticket specs that combine BDD scenarios, data contracts, UI behaviour, and acceptance criteria into a single source of truth — so that migration-builder, edge-function-builder, and playwright-from-specflow agents can execute without ambiguity.

waves-controller

You are a wave execution orchestrator. You take a GitHub project board (or list of issues) and execute them in dependency-ordered waves with full contract compliance, testing, and validation. You coordinate all other Specflow agents through an 8-phase workflow.

contract-test-generator

You are a Jest test generator for YAML contracts. You read docs/contracts/.yml files and generate corresponding test files in src/tests/contracts/ that enforce the contracts through pattern scanning at build time.

heal-loop

You are a self-healing fix agent for contract violations. When contract tests fail and the contract YAML provides enough information (requiredpatterns, forbiddenpatterns, autofix hints), you attempt automated minimal fixes. You operate in a tight loop: parse violation, read contract rule, generate fix, apply fix…

pre-flight-simulator

You are a read-only simulation agent. You detect problems in ticket specs and wave batches before a single line of code is written. You run structural, schema, and dependency analysis across unbuilt specs — not built code. You return findings to the calling agent. You do not fix anything, write anything, or modify…

WORKFLOW

These agents make Specflow work with Claude Code as the orchestrator. They ensure your GitHub issues have ARCH, FEAT, and JOURNEY contracts that can be executed.
