A plugin for updating Go, Python, and Node.js dependencies, meaning the external packages a project uses. It detects the project type and checks changes with builds, tests, and linting.

Use it to update packages, address security advisories, validate dependency changes, and prepare a review plan for major or held-back upgrades.

It reduces the risk of package upgrades breaking the project and helps identify which update caused a failure.

Security

Grade A, and why

deps 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.

{
  "name": "deps",
  "version": "2.0.6",
  "description": "Update dependencies safely across Go, Python, and Node ecosystems. Use when the user asks to bump, update, or upgrade dependencies, packages, or deps; run a dependency bump/upgrade; fix Dependabot or security advisories; or refresh outdated packages. Triggers on phrasings like 'bump the deps', 'bump dependencies on <branch>', 'update packages on main', or 'run a dep upgrade'. Auto-detects ecosystems (Go/Python/Node), applies safe patch and minor updates with build, test, and lint validation, bisects failures to isolate bad packages, and surfaces a prioritized plan for major or held packages that need manual review.",

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.
