This page tells what claudetto does and which plugins it has. It is for new users, who read it before the install steps. It also shows where to read next for each task.

What claudetto Does

claudetto is a Claude Code plugin marketplace for software engineering. It changes Claude Code through the Mod API, settings, hooks, skills, agents, and output styles. It does not patch the binary. Its goal is the highest quality for the lowest token cost. claudetto 0.1.0 is the restart of the earlier plugin dotclaude 1.0.0, with a new name and no compatibility with it. claudetto needs Claude Code 2.1.302 or later.

claudetto does the following:

• Gives permission rules and a sandbox in the settings snippet. The rules ask or deny destructive actions, as Guards describes.
• Gives ask rules for recursive rm calls in the settings snippet.
• Turns off the built-in compaction and replaces it with a handoff. See Handoff.
• Selects the output style claudetto:Concise with the settings snippet. The style leads with the result and keeps replies short.
• Changes parts of the built-in system prompt and of the tool descriptions, through the Mod API. See Prompt.
• Gives Claude six agents, each with a model, an effort, and a turn limit: reviewer, implementer, debugger, investigator, planner, and researcher. See Agents.
• Plans and tracks a change with files, skills, and the minispec CLI. See MiniSpec.
• Shows the folder, the git state, the active change, the model and effort, the context, the cost, and the usage limits. It shows them in a status line. See Status Line.

The Plugins

The core plugin is claudetto. Each add-on is a separate plugin. Each add-on works without the core plugin.

Plugin	What it does	Reference
claudetto	The core plugin. It gives the output style, the agents, the guards, the status line, the handoff, MiniSpec, the prompt profile, the setup, and the opt-in second opinion (second_opinion).	Overview, Architecture, Decision API
claudetto-codegraph	Gives Claude the code graph of a project from the CodeGraph CLI codegraph.	Code Graph
claudetto-browser	Drives a browser with agent-browser. It answers each WebSearch call with a headless browser search.	Browser
claudetto-docs	Gets current library and API docs with the Context7 CLI ctx7.	Library Docs
claudetto-sessions	Measures the start of a session by source, and the usage of each run.	Sessions
claudetto-lab	Gives tools for plugin authors: a sandbox for Claude Code, a request capture, the JSON Schema of settings.json, and an eval compare.	Lab
claudetto-you-should-know	Opt-in. Shows one thing to know before Claude changes something.	You Should Know

The marketplace and the install steps are in Add-Ons and Install.

The Principles

The design principles are on Design. These are some of them.

• Only documented extension points.
• No model call for a check that a script can make.
• One owner for each bound.
• Each plugin works alone.

Concepts and Evidence

Page	What it holds
Design	The design principles of claudetto, and why each is in force.
Decisions	The design decisions of claudetto, in groups.
Evidence	The measured facts that the decisions use.
Evals	What the evals measure, and the Claude Code version that they need.
Prompt	The output style, the prompt sections, and the tool texts.
Request Build	The system prompt sections, the attachments, and the cache of a request.
Release History	Where the notes of each release are.

The CHANGELOG lists each release. The section of the version in package.json holds the changes of the release in progress until that version has a tag. After the tag, the [Unreleased] section holds the new changes.

Source Labels

The evidence pages label each fact with its source.

Label	Source
official	Anthropic documentation or support pages
binary	read from the installed Claude Code bundle, never patched
capture	a request body that Claude Code sent to a local listener
measured	a run or a transcript scan on the maintainer's machine
reported	user reports
inference	a conclusion from the facts above

A binary fact names the Claude Code version that it is for. The extracts of the bundle are in the git-ignored external/ folder, as Claude Code Internals describes.
