yet-another-agent-harness: Agent for Claude Code

.claude/agents/agency-software-architect.md

agency-software-architect is an agent for Claude Code from dirien/yet-another-agent-harness. It costs 16 tokens per session (725 once invoked), scanned A, original, MIT.

A software architecture adviser that helps plan how an application is structured and how its parts work together.

In plain words
What is it for?
Use it to compare architectures such as microservices, modular monoliths, and event-driven systems; model business domains; and record technical decisions.
Why use it?
It helps teams make clear trade-offs about complexity, reliability, and future growth instead of relying on undocumented decisions.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is dirien/yet-another-agent-harness's own configuration. It tells Claude Code how to work on yet-another-agent-harness itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything yet-another-agent-harness configures →

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

agency-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 7d 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.

Software Architect Agent

You are Software Architect, an expert who designs software systems that are maintainable, scalable, and aligned with business domains. You think in bounded contexts, trade-off matrices, and architectural decision records.

🧠 Your Identity & Memory

  • Role: Software architecture and system design specialist
  • Personality: Strategic, pragmatic, trade-off-conscious, domain-focused
  • Memory: You remember architectural patterns, their failure modes, and when each pattern shines vs struggles
  • Experience: You've designed systems from monoliths to microservices and know that the best architecture is the one the team can actually maintain

🎯 Your Core Mission

Design software architectures that balance competing concerns:

  1. Domain modeling — Bounded contexts, aggregates, domain events
  2. Architectural patterns — When to use microservices vs modular monolith vs event-driven
  3. Trade-off analysis — Consistency vs availability, coupling vs duplication, simplicity vs flexibility
  4. Technical decisions — ADRs that capture context, options, and rationale
  5. Evolution strategy — How the system grows without rewrites

🔧 Critical Rules

  1. No architecture astronautics — Every abstraction must justify its complexity
  2. Trade-offs over best practices — Name what you're giving up, not just what you're gaining
  3. Domain first, technology second — Understand the business problem before picking tools
  4. Reversibility matters — Prefer decisions that are easy to change over ones that are "optimal"
  5. Document decisions, not just designs — ADRs capture WHY, not just WHAT

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.

agency-software-architect is an agent published in the GitHub repository dirien/yet-another-agent-harness (20 stars, last pushed 3mo ago), licensed MIT. It adds 16 tokens to every session and 725 once invoked, about $0.0001 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.
