What is set-project-profile-default?

A command for choosing the default project profile used when starting a new project without specifying one. A profile is a saved set of project settings such as language, framework, or tools.

Use it to view or change the default profile, including presets for Go, Python APIs, or projects using tools such as MongoDB, Next.js, Tailwind, and Docker.

It avoids repeatedly selecting the same project setup whenever a new project is created.

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	$0.00008	$0.00850
Opus 5.5	$0.00003	$0.00340
Sonnet 5.5	$0.00002	$0.00170
Haiku 4.5	$0.00001	$0.00085

Security

Grade A, and why

set-project-profile-default 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.

Set Project Profile Default

Set which profile /new-project uses by default when no profile is specified.

Arguments: $ARGUMENTS

Usage

/set-project-profile-default go              → sets default_profile = go
/set-project-profile-default clean           → sets default_profile = clean
/set-project-profile-default default         → sets default_profile = default
/set-project-profile-default python-api      → sets default_profile = python-api
/set-project-profile-default mongo next tailwind docker
  → creates/updates [user-default] profile with those settings
  → sets default_profile = user-default
/set-project-profile-default (no args)
  → shows current default, asks what to change

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 [section] names (these are the available profiles)
Current default_profile value from [global] (if set)

2. Parse arguments

$ARGUMENTS can be:

A) No arguments — show current state and ask:

Display the current default_profile value (or "not set" if absent)
List all available profiles with a one-line summary of each
Ask via AskUserQuestion: "Which profile should be the default?"
- Options: list all profile section names from the conf file
After selection, proceed to Step 3

B) Single argument matching an existing [section] name (e.g., go, clean, default, api, vue, python-api):

Proceed to Step 3 with that profile name

C) Multiple arguments (e.g., mongo next tailwind docker):

Parse as shorthand options using the same parser as /new-project:
- Languages: node, go, python
- Frameworks: vite, react, next, vue, nuxt, svelte, sveltekit, angular, astro, fastify, express, hono, gin, chi, echo, fiber, stdlib, fastapi, django, flask
- Database: mongo, postgres, mysql, mssql, sqlite
- Hosting: dokploy, vercel, static
- Package managers: pnpm, npm, bun, pip, uv, poetry
- Options: seo, ssr, tailwind, prisma, docker, ci, multiregion
- Analytics: rybbit
- MCP: playwright, context7, rulecatch
Create or update a [user-default] section in the conf file with the parsed settings
Set default_profile = user-default in [global]
Proceed to Step 4 (confirmation)

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.
