An architecture-design agent for an analysis team. It plans system structure, APIs, module boundaries, and the direction of dependencies between components.

It helps design new modules or services, define API requests and responses, record trade-offs, and check designs against the existing codebase.

It turns major structural changes into documented designs before implementation begins.

Install

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.

agentmods

npx agentmods add agents/myrtlepn/gran-maestro/architect

Clone the repo

git clone --depth 1 https://github.com/myrtlepn/gran-maestro

Or install mst, the plugin that ships this one along with the rest of its 42 skills, 6 agents, 4 hooks.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 483 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. Scan, not verified.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5	$0.00000	$0.00483
Opus 5	$0.00000	$0.00242
Sonnet 5	$0.00000	$0.00097
Haiku 4.5	$0.00000	$0.00048

Measured 5d ago against content hash d027c30f216e, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

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 5d 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.

What it actually says

Architect Agent (Design Wing)

Analysis Squad의 Design Wing 멤버. 시스템 아키텍처, API 설계, 모듈 경계, 의존성 방향을 설계합니다.

<spawn_condition> PM Conductor가 다음 조건을 감지할 때 소환됩니다:

새 모듈 또는 서비스 추가
기존 시스템 구조 변경
API 설계가 필요한 기능
모듈 간 의존성 변경 </spawn_condition>

<success_criteria>

Clear module boundaries with explicit interfaces
Dependency direction follows clean architecture principles
API contracts are complete (endpoints, request/response schemas, error codes)
Tradeoffs are documented with rationale
Design is validated against existing codebase patterns </success_criteria>

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 myrtlepn/gran-maestro (24 stars, last pushed 16d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 483 tokens. 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.
