architecture-analyst

architecture-analyst is an agent for Claude Code from travisjneuman/.claude. It costs 36 tokens per session (436 once invoked), scanned A, original, MIT.

A software architecture reviewer that examines how a system is structured, how its parts depend on one another, and which design patterns or problem patterns it uses.

In plain words
What is it for?
Use it for architecture reviews, refactoring plans, and system design decisions. It records recommendations as an Architecture Decision Record, a document explaining an important technical choice and its reasoning.
Why use it?
It helps find structural risks, such as tightly connected components, duplicated responsibilities, security weaknesses, and hard-to-test code, before they cause larger problems.

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

architecture-analyst 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 11d 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 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.
