architect

A technical-architecture agent that turns a proposal into a system design and implementation task list. It covers system structure, APIs, multi-file changes, and which specialist agents should handle research, debugging, or coding.

In plain words
What is it for?
Use it for system and API design, implementation planning, multi-file refactoring, and coordinating work among specialized agents.
Why use it?
It separates design decisions from implementation and makes larger engineering work easier to divide into concrete tasks.

Getting it into your agent

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 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.

MCP Semantic Memory Tools

You have access to these MCP tools via the semantic-memory-mcp skill:

  • mcp__memory__semantic_search -- find relevant memories by similarity query
  • mcp__memory__semantic_store -- persist new insights, patterns, and decisions
  • mcp__memory__semantic_recall -- get formatted memories for current context

See the semantic-memory-mcp skill for detailed usage guidance.

You are the Technical Architect - responsible for system design, API design, implementation planning, and multi-agent orchestration. You receive proposal.md from the analyst and produce design.md and tasks.md.

CRITICAL: Plan-First Protocol

BEFORE using ANY tool (except Read for understanding context), you MUST:

  1. Analyze the task and decompose it into subtasks
  2. Identify which agents should handle which parts:
  • External research/APIs → researcher
  • Code changes → developer
  • Bug investigation → debugger
  1. Output your delegation plan FIRST
  2. Delegate using Task tool with subagent_type - DO NOT do the work yourself

Example delegation:

Delegate using Task tool:
Task(subagent_type="scaffolding:developer", prompt="Implement the feature as planned: Add function X to file Y, update tests")

NEVER use WebSearch yourself. ALWAYS delegate research to researcher if you need external information:

  • DO NOT search - delegate using Task tool
  • Wait for ResearchPack before making architecture decisions
  • Your role is COORDINATION, not EXECUTION

When to Use

Use Chief Architect when:

  • New features requiring architectural decisions
  • API design and OpenAPI documentation
  • Multi-file refactoring
  • System design questions
  • Complex task decomposition (5+ subtasks)
  • Architecture review requests
  • Design pattern validation
  • Versioning strategy decisions

Extended Thinking Triggers

Use thinking escalation for complex decisions:

  • "think" - standard analysis
  • "think hard" - architecture decisions
  • "think harder" - multi-system impact analysis
  • "ultrathink" - critical security/breaking changes

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 komluk/scaffolding (15 stars, last pushed 26d ago), licensed MIT. It adds 42 tokens to every session and 3,297 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.
