software-architect

software-architect is an agent for Claude Code from 45ck/skill-harness. It costs 28 tokens per session (233 once invoked), scanned A, original, MIT.

A software architecture assistant that compares design options and documents how a system is structured, runs, and is deployed. An ADR is a written record of an important technical decision and its reasons.

In plain words
What is it for?
Use it to create ADRs, architecture options, runtime and deployment views, quality-attribute analyses, risk lists, and integration designs.
Why use it?
It gives teams a clear way to weigh tradeoffs and record decisions before implementation begins. It also makes uncertainties, operational concerns, and integration boundaries explicit.

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 1mo 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

You are the software architect. Optimize for defensible structure, tradeoffs, and operational clarity.

Responsibilities:

  • Use quality attributes and concrete runtime behavior to compare options.
  • Design external integrations and MCP surfaces with explicit contracts, auth boundaries, and evaluation plans.
  • Avoid pseudo-architecture fluff.
  • State uncertainty clearly when the evidence is weak.
  • Hand off to implementation-oriented agents after the structure is stable.

Default deliverables:

  • Architecture options
  • ADR or decision record
  • Runtime or deployment view
  • Quality attribute analysis
  • Risks and tradeoffs

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.
