In plain words
What is it for?
Use it to build Gepetto, run its Java tests, start the application, execute task files, or follow its code-style and error-handling rules.
Why use it?
It tells coding agents how the project is organized, how to build and test it, and which commands the application supports.

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

gepetto CLAUDE.md 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 6d 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.

Gepetto Development Guide

Build Commands

# Build the project
./mvnw clean install

# Quick build (skip tests)
./mvnw clean package -P dev

# Run all Java tests
./mvnw test

# Run a single Java test
./mvnw test -Dtest=TestClassName#testMethodName

# Run application with specific command
./mvnw spring-boot:run -Dspring-boot.run.arguments="help"
./mvnw spring-boot:run -Dspring-boot.run.arguments="run gepetto/tasks/login.gpt --debug"

# Run from JAR (after building)
java -jar target/gepetto-0.0.1-SNAPSHOT.jar help

CLI Commands

  • init: Initialize a new Gepetto project (--var, -v to define variables)
  • run <taskfile>: Execute a task file (options: --var, -v, --debug, -d, --no-report)
  • version: Show version information
  • help [command]: Display help for commands

Code Style Guidelines

  • Package structure: Maintain sh.gepetto.app with functional areas (config, model, service, cli)
  • Imports: No wildcards, standard Java first, then framework-specific imports
  • Naming: PascalCase for classes, camelCase for methods/variables, UPPER_SNAKE_CASE for constants
  • Error handling: Use try-catch with specific exceptions, log with SLF4J, return appropriate status codes
  • Dependency injection: Use Spring's constructor injection
  • Documentation: Maintain Javadoc for classes and public methods

Project Structure

After initialization, a Gepetto project will have the following structure:

gepetto/
  ├── config.yaml      # Configuration
  ├── tasks/           # Generic automation tasks
  │   ├── login.gpt    # Example task file 
  └── results/         # Execution results

Task File Format

# Task Name
description: "Brief description of task purpose"
tags: [tag1, tag2]
author: "Author Name"
created: "YYYY-MM-DD"

Task:
  Step 1 in natural language.
  Step 2 in natural language.
  ...
  Verification step in natural language.

Product Overview

Gepetto enables natural language task automation without programming knowledge. The app parses plain English task instructions, executes them automatically, and generates user-friendly reports. Focus on maintaining the core components: task parsing, execution service, and CLI commands.

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.
