What is platform-maker?

A generator for complete SaaS platforms from a YAML configuration file. SaaS means software delivered as an online service; the generated platform can include application screens, database structures, server routes, translations, payments, referrals, and deployment settings.

Use it to generate the starting structure for a SaaS product, including its web interface, database, API routes, internationalization, payment integration, referral system, and deployment configuration.

It reduces the amount of repetitive setup needed to start a configurable online product. It also records important generation decisions and can retry fixable build or type errors.

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	$0.00071	$0.07260
Opus 5	$0.00036	$0.03630
Sonnet 5	$0.00014	$0.01452
Haiku 4.5	$0.00007	$0.00726

Security

Grade D, and why

platform-maker scanned grade D with 3 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 3d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (templates/router.template.ts, templates/schema.postgres.template.ts, templates/seed.template.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Platform Maker Skill

Overview

This skill autonomously generates complete SaaS platforms from a YAML configuration. It runs with minimal user interruption, spawning parallel subagents that communicate via shared memory to build faster.

Invocation

/platform-maker
/platform-maker /path/to/project
/platform-maker /path/to/project/platform.config.yaml

AUTONOMOUS OPERATION PRINCIPLES

Minimal Interruption Policy

ONLY interrupt the user for:

Initial project folder (if not provided)
Missing critical config information that cannot be inferred
Destructive command confirmation (see safeguards)
Unrecoverable errors after 3 retry attempts

DO NOT interrupt for:

Validation errors you can fix automatically
Missing optional fields (use sensible defaults)
Build errors (fix and retry)
Type errors (fix and retry)
Minor decisions (make the best choice and document it)

Decision Logging (Enhanced)

Log ALL significant events to .platform-maker/decisions.log:

Log Format:

[YYYY-MM-DD HH:MM:SS] TYPE: Message

What ships with it

10 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

platform-maker is a skill published in the GitHub repository djbelieny/nova (5 stars, last pushed 1mo ago), licensed MIT. It adds 71 tokens to every session and 7,260 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
