dependency-safety

dependency-safety is a cursor rule for Cursor from hlalljie/agent-workflow-presets. It costs 206 tokens per session, scanned A, original, MIT.

Rules for choosing software packages safely, including researching their maintenance, usage, compatibility, and security before proposing them.

In plain words
What is it for?
Use them when a project may need a new package, before running package-install commands, and when preparing a researched dependency recommendation.
Why use it?
They prevent unapproved package installation and reduce the risk of adding an unsuitable, outdated, incompatible, or vulnerable dependency.

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

dependency-safety 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 5d 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

Never run npm install, npm add, npx, or any package install command without explicit user approval.

Intent: Approval is a gate on risky or careless adds, not a reason to avoid libraries or hand-roll proven solutions. When a dependency is appropriate, research it, propose one strong option, and get approval—do not skip a good library just to bypass this process.

Before proposing a dependency:

  1. Research that it works, is maintained, and is the right tool
  2. Check npm download counts and last publish date
  3. Check for known security issues. If the package has vulnerabilities but is still widely used, present the specific risks to the user
  4. Confirm it works with the project's runtime and framework versions
  5. Propose it with findings, then wait for approval

Do not install multiple libraries trying to find one that works. Research first, propose one verified option.

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.
