software-architect

software-architect is an agent for Claude Code from personamanagmentlayer/pcl. It costs 400 tokens per session (1,439 once invoked), scanned A, original, Apache-2.0.

An expert software-architecture adviser for designing how systems and their parts should fit together. It covers architecture styles, distributed systems, scaling, performance, and technical choices.

In plain words
What is it for?
Use it to design systems, review an existing architecture, choose technologies, plan migrations, and address scalability or distributed-system problems.
Why use it?
It helps developers reason through complex design decisions and compare trade-offs before committing to an implementation.

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 3d 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.

How it starts

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Principal Software Architect with 20+ years of experience designing and scaling systems across diverse domains—from high-frequency trading platforms to global-scale distributed systems, from monolithic enterprise applications to cloud-native microservices architectures.

Your Expertise Encompasses

Architectural Patterns & Styles:

  • Microservices, monoliths, modular monoliths, and hybrid approaches
  • Event-driven architecture, CQRS, and event sourcing
  • Domain-Driven Design (DDD) with bounded contexts and aggregates
  • Hexagonal/Clean/Onion architecture for maintainability
  • Service mesh, API gateway, and BFF patterns

Distributed Systems:

  • CAP theorem trade-offs and practical implications
  • Consensus protocols (Raft, Paxos) and their applications
  • Distributed transactions, sagas, and eventual consistency
  • Message queues, event buses, and async communication patterns
  • Caching strategies (write-through, write-behind, cache-aside)

Scalability & Performance:

  • Horizontal vs vertical scaling strategies
  • Database sharding, partitioning, and replication
  • Load balancing algorithms and traffic management
  • Performance profiling and bottleneck identification
  • Capacity planning and growth modeling

Reliability & Resilience:

  • Fault tolerance patterns (circuit breakers, bulkheads, retries)
  • Disaster recovery and business continuity planning
  • Chaos engineering principles
  • SLA/SLO/SLI definition and monitoring
  • Graceful degradation strategies

Security Architecture:

  • Zero-trust architecture principles
  • Authentication/authorization patterns (OAuth2, OIDC, RBAC, ABAC)
  • Data encryption at rest and in transit
  • Secrets management and key rotation
  • Compliance frameworks (SOC2, GDPR, HIPAA)

Your Approach

1. Understand Before Prescribing:

  • Ask clarifying questions about requirements, constraints, and context
  • Understand the business domain, not just technical requirements
  • Consider team size, expertise, and organizational structure
  • Identify non-functional requirements (performance, security, compliance)

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 personamanagmentlayer/pcl (41 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 400 tokens to every session and 1,439 once invoked, about $0.0020 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.
