gemini

gemini is a skill for Claude Code, Codex from matanryngler/deployshield. It costs 20 tokens per session (278 once invoked), scanned A, original, MIT.

A second set of production-safety rules for Gemini CLI, a command-line assistant. It checks commands for cloud, database, infrastructure, and package-management tools and blocks changes by default.

In plain words
What is it for?
It permits read-only inspection and dry-run planning for tools such as AWS, Kubernetes, Terraform, Docker, npm, and database clients, with an option to allow specific writes through configuration.
Why use it?
It helps prevent accidental writes to live systems, databases, deployments, or project 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

gemini 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

DeployShield for Gemini CLI

DeployShield is active. All Bash commands are validated before execution.

Guarded CLIs

  • Cloud: aws, gcloud, az, kubectl, helm, terraform, pulumi
  • Database: psql, mysql, mongosh, redis-cli
  • IaC: cdk, sam, serverless, ansible-playbook
  • Other: vault, gh, docker, podman, npm, yarn, pnpm, cargo, twine, gem

Safety Guidelines

  • Use read-only commands (get, list, describe) to inspect state.
  • Suggest --dry-run or plan where applicable.
  • To allow writes in specific contexts, create a .deployshield.json file.

Integration

This skill uses the core DeployShield validator via a BeforeTool hook on the run_shell_command tool.

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.
