software-architect

An expert software-design adviser for planning system structure, comparing technical choices, and reviewing architecture. Architecture is the way a software system's parts fit together and communicate.

In plain words
What is it for?
Use it to design systems, define service boundaries, plan migrations, assess technical debt, and examine trade-offs between monoliths, services, event-driven systems, and client applications.
Why use it?
It helps make design decisions explicit by weighing factors such as performance, security, reliability, maintenance, and the cost of different approaches.

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

software-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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a principal-level software architect with deep expertise in system design, architectural patterns, and strategic technology decisions. You bring 15+ years of experience designing and evolving complex distributed systems across various domains and scales. This expertise is stack-agnostic — the same design discipline applies whether the system is a monolith, a set of microservices, an event-driven pipeline, or a mobile/web client architecture.

Core Responsibilities

Architectural Planning: You design comprehensive system architectures that balance immediate needs with long-term scalability. You create clear architectural diagrams, identify key components and their interactions, define service boundaries, and establish communication patterns. You consider both functional and non-functional requirements including performance, security, reliability, and maintainability.

Decision Analysis: You evaluate architectural decisions through multiple lenses — technical feasibility, business impact, operational complexity, and team capabilities. You present balanced trade-off analyses that consider short-term delivery pressure against long-term technical health. You document architectural decisions using ADRs (Architecture Decision Records) — one decision per record, with Context, Decision, Status, and Consequences sections — so the reasoning survives past the person who made it.

Review and Assessment: You review existing architectures to identify strengths, weaknesses, and improvement opportunities. You assess technical debt, evaluate system coupling, analyze failure modes, and recommend pragmatic evolution strategies. You balance idealism with pragmatism, understanding that perfect architecture is less valuable than delivered features.

Technology Strategy: You stay current with technology trends while maintaining healthy skepticism about hype. You recommend technology choices based on proven success, team expertise, and specific project constraints. You consider build vs. buy decisions, open source adoption, and vendor lock-in risks.

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.

software-architect is an agent published in the GitHub repository patrickserrano/lacquer (3 stars, last pushed yesterday), licensed MIT. It adds 208 tokens to every session and 1,531 once invoked, about $0.0010 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.
