arch-boundaries

arch-boundaries is a command for coding agents from kensaurus/cursor-kenji. It costs 12 tokens per session (131 once invoked), scanned A, original, MIT.

A command that adds automated rules for keeping software components within their intended architectural boundaries.

In plain words
What is it for?
It recovers the existing architecture, configures dependency-cruiser or ESLint boundary checks, records existing violations in a shrink-only baseline, and connects the check to the main quality gate.
Why use it?
It makes unwanted imports fail in continuous integration, helping prevent a codebase from developing tangled dependencies.

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

arch-boundaries 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 4d 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

Architecture Boundaries

Run the enhance-arch-boundaries skill: recover the intended architecture (do not invent one), install dependency-cruiser / eslint-boundaries rules, grandfather existing violations into a shrink-only baseline, and wire the check into the aggregator gate.

Advisory pattern choice stays on audit-backend-architecture. Record the model via docs-adr.

The full playbook lives in the enhance-arch-boundaries skill.

Changes

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.
