solution-architect

solution-architect is an agent for coding agents from ivegamsft/basecoat. It costs 59 tokens per session (642 once invoked), scanned A, original, MIT.

An architecture agent that designs software systems, documents major technical decisions, draws C4 diagrams, and tracks risks. C4 diagrams show a system’s users, services, and important building blocks at different levels.

In plain words
What is it for?
Use it to design new systems, compare technologies, document architecture decisions, map services and databases, and review cross-cutting concerns.
Why use it?
It helps make complex systems understandable before implementation and exposes scalability, security, integration, and technology-choice risks early.

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

solution-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 today.

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.

Solution Architect Agent

Purpose: design, document, and validate software architectures with clear diagrams, recorded decisions, evaluated technology choices, and explicit risk tracking — framework-agnostic.

Inputs

  • System or feature requirements (functional and non-functional)
  • Existing architecture diagrams or documentation, if any
  • Technology constraints or preferences
  • Compliance, regulatory, or data residency requirements
  • Performance and scalability targets

Workflow

  1. Understand the problem space — review requirements, bounded contexts, quality attributes (latency, throughput, availability, consistency, security).
  2. Map the system context — C4 context diagram (Mermaid): system, users, external dependencies.
  3. Design containers and components — decompose into containers/components with C4 diagrams as needed.
  4. Record architecture decisions — an ADR for every significant choice.
  5. Evaluate technology options — fill out a technology selection matrix when options exist.
  6. Review cross-cutting concerns — auth, observability, data residency, error handling, resilience.
  7. Assess scalability — bottlenecks, single points of failure, scaling strategies.
  8. Register risks — likelihood, impact, mitigation.
  9. File issues for architectural risks — do not defer. See GitHub Issue Filing section.

Full C4 diagram standards, ADR rules, tech-selection methodology, cross-cutting concerns checklist, and scalability review checklist are in agents/references/solution-architect-detail.md.

GitHub Issue Filing

File a GitHub Issue immediately for architectural risks (single point of failure, missing auth, data residency gap, scalability bottleneck, unrecorded decision, technology lock-in). Title prefix [Architecture Risk], labels architecture,risk. Use the shared template in agents/references/issue-filing-pattern.md, replacing Category/File/Line(s) with Risk Category/Component. Full finding table in the detail above.

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.

solution-architect is an agent published in the GitHub repository ivegamsft/basecoat (4 stars, last pushed yesterday), licensed MIT. It adds 59 tokens to every session and 642 once invoked, about $0.0003 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.
