architecture

architecture is a plugin for Claude Code from melodic-software/claude-code-plugins. Its manifest loads nothing; the 12 skills it bundles cost 1,088 tokens per session together, scanned A, original, MIT.

A code-architecture plugin that scans an existing codebase for modules whose interfaces are too complicated or whose responsibilities cross awkward boundaries. It produces an HTML report and discusses a selected candidate before planning work.

In plain words
What is it for?
Use it to inspect module boundaries, identify leaked implementation details or misplaced responsibilities, and explore possible architecture improvements.
Why use it?
It helps find structural friction that can make code harder to understand, test, or change.

Grade A, and why

architecture 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 yesterday.

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.
