What is add-project-setup?

An interactive command that creates a named project profile in a configuration file. A project profile is a reusable set of setup choices, such as the programming language and project type.

Creating profiles that can later be selected when starting a project or set as the default, with validation for names and reserved entries.

It avoids repeating the same setup decisions for each new project and checks existing profiles to prevent accidental duplicates.

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	$0.00007	$0.01292
Opus 5.5	$0.00003	$0.00517
Sonnet 5.5	$0.00001	$0.00258
Haiku 4.5	$0.00001	$0.00129

Security

Grade A, and why

add-project-setup 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 2mo 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.

Add Project Setup — Interactive Profile Creator

Create a named, reusable profile in claude-mastery-project.conf through an interactive wizard. The profile can then be used with /new-project my-app <profile-name> or set as default with /set-project-profile-default <profile-name>.

Arguments: $ARGUMENTS

Steps

1. Read the config file

Read claude-mastery-project.conf from the project root. If not found, check ~/.claude/claude-mastery-project.conf.

Extract all existing [section] names to prevent duplicates.

2. Get profile name

If $ARGUMENTS provides a name, use it. Otherwise ask:

"What should this profile be called?"

Validate:

Lowercase letters, numbers, and hyphens only
Cannot be global or clean (reserved)
Cannot match an existing section name (warn and ask to overwrite or pick another)
Examples: my-api, dashboard, landing-page, go-microservice

3. Ask questions (sequential, via AskUserQuestion)

Skip any question if the answer was provided in $ARGUMENTS as shorthand.

Q1: Language

"What language will this project use?"

Node.js / TypeScript — JavaScript ecosystem (Recommended)
Go — Systems language, compiled binaries
Python — Data science, APIs, scripting

Q2: Project Type

"What type of project?"

Web App — Frontend with UI (SPA or SSR)
API — Backend REST/GraphQL service
Full-Stack — Frontend + backend in one repo
CLI — Command-line tool

Q3: Framework (filtered by language + type)

Node.js + Web App / Full-Stack:

Vite + React — Fastest HMR, lightweight (Recommended)
Next.js — SSR, server components, built-in routing
Vue 3 — Composition API, progressive framework
Nuxt — Vue with SSR, auto-imports, file-based routing

Node.js + Web App (also):

Svelte — Compiled, minimal runtime
SvelteKit — Svelte with SSR, file-based routing
Angular — Enterprise, batteries-included
Astro — Content-first, island architecture

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.
