An interactive workflow for creating and deploying Massdriver infrastructure bundles, which are reusable packages that define cloud resources with Terraform. It guides setup, scaffolding, publishing, deployment, testing, and compliance fixes.

It is for creating resources such as databases or storage buckets, publishing their bundle code, deploying it to a Massdriver project, checking deployment logs, and addressing Checkov compliance findings.

It brings the steps for building and repeatedly deploying an infrastructure bundle into one guided process.

develop — Command for Claude Code by massdriver-cloud/claude-plugins

Install

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

git clone --depth 1 https://github.com/massdriver-cloud/claude-plugins

Made for: Claude Code.

Or install massdriver, the plugin that ships this one along with the rest of its 1 skill, 5 commands, 4 agents, 1 hook, 1 MCP server.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00014	$0.00422
Opus 5.5	$0.00006	$0.00169
Sonnet 5.5	$0.00003	$0.00084
Haiku 4.5	$0.00001	$0.00042

Security

Grade A, and why

develop 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 1mo 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

Bundle Development

Start the bundle-dev agent to guide you through creating and testing a Massdriver infrastructure bundle.

What This Does

Setup - Verify MCP auth (get_viewer) and select/create the target project + environment (MCP create_project / create_environment)
Gather requirements - Understand your use case, developer UX needs, and compliance strategy
Scaffold bundle - Create massdriver.yaml, Terraform code, and supporting files
Publish bundle (CLI) - mass bundle publish --development
Add to project blueprint (MCP) - add_component (once per project)
Pin development channel (MCP) - update_instance with version latest+dev
Deploy & iterate (MCP) - create_deployment + get_deployment_logs follow:true, re-publishing and redeploying as code changes
Remediate compliance - Fix Checkov findings according to your strategy
Journal results (MCP) - Record what was tested via update_environment

Usage

Provide a description of what bundle you want to create:

/massdriver:develop PostgreSQL database for application backends with dev/staging/prod presets

/massdriver:develop S3 bucket for static asset storage with CloudFront CDN

/massdriver:develop EKS cluster with managed node groups and cluster autoscaler

Instructions

Use the Task tool to spawn the bundle-dev agent with the user's use case description. The agent will handle the interactive workflow, starting with credential/environment setup.

If no use case was provided in the command arguments, ask the user what bundle they want to develop.

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.
