A repository analysis and refactoring tool for finding dependencies that make changes spread between documents, code modules, applications, or repositories.

Use it to locate and reduce connections between project parts while preserving behavior, and to record larger design changes for later work.

It helps identify where parts of a project are unnecessarily tied together, which can make even small changes risky or expensive.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

Security

Grade A, and why

coupling 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 2d 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.

{
  "name": "coupling",
  "version": "0.4.0",
  "description": "Iteratively reduces coupling in documents, code modules, applications, or repositories: scans for change-transmitting dependencies against a coupling model (strength ladder, connascence, volatility), verifies each finding, applies a budgeted batch of safe behavior-preserving reductions, and keeps a ledger so structural candidates route to design and later runs resume. When a value changes, it finds and classifies every site stating it and converts setup sites to references.",

What it installs

The manifest is a name and a version. 1 skill travel with it, and installing the plugin installs all of them — 200 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
