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.

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 | $0.00753 |
| Opus 5.5 | $0.00006 | $0.00301 |
| Sonnet 5.5 | $0.00003 | $0.00151 |
| Haiku 4.5 | $0.00001 | $0.00075 |
Grade A, and why
gen 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 19d 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.
How it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Quick Bundle Generation
Generate a Massdriver bundle scaffold based on a use case description. This is the non-interactive "quick gen" mode - it creates the bundle files and hands off to you for testing.
What This Does
- Ask a few quick questions about the bundle
- Generate the complete bundle structure
- Run local validation (
mass bundle build,tofu validate) - Hand off to you for deployment and testing
Usage
/massdriver:gen RDS MySQL database for OLTP workloads
/massdriver:gen Lambda function with API Gateway trigger
/massdriver:gen S3 bucket for data lake landing zone
Instructions
1. Quick Requirements
Ask the user (if not clear from the description):
- Cloud provider (AWS, GCP, Azure)?
- What connections does it need (network, credentials)?
- What artifact does it produce?
- Any specific presets they want?
2. Generate Bundle Structure
Create the bundle in bundles/<bundle-name>/:
bundles/<bundle-name>/
├── massdriver.yaml # Bundle manifest with params, dependencies, resources
├── README.md # Bundle documentation
├── operator.md # Runbook template
└── src/
├── main.tf # Primary Terraform code
├── resources.tf # massdriver_resource resources
└── .checkov.yml # Checkov skip rules (if any)
3. Apply Best Practices
- Params: Focus on 3-5 developer-facing questions, use presets
- 80/20 rule: Cover common use cases, don't over-generalize
- Dependencies: Use existing resource types (
mass resource-type list) - Runbook:
operator.mdis engineer-facing — no templating-context meta or config snapshots (the product has a config panel), no explainer headings; actionable ops sections with runnable commands, resource-sourced values wrapped in{{#resources.<name>}}guards - Resources: Match the resource type's schema exactly
- Provider:
mass resource-type get <platform>FIRST, then write provider using only those fields — resource types and providers are 1:1 - Compliance: Default to secure settings, add
halt_on_failurefor prod
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.

gen is a command published in the GitHub repository massdriver-cloud/claude-plugins (2 stars, last pushed 19d ago), licensed Apache-2.0. It adds 14 tokens to every session and 753 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
