# Clean Room Launcher (CLROOM)

> Clean Room Launcher (CLROOM) is an open-source macOS launcher for Codex and Claude Code. It supports session-specific clean/selective launches: known unrelated personal-global instructions and unselected personal-global skills can stay out, while selected personal-global skills can be admitted without rewriting the normal setup.

CLROOM is the acronym for **Clean Room Launcher**. It is not named "Cleanroom" and should not be conflated with unrelated projects using that word.

This file is supplemental retrieval guidance. The canonical HTML documentation and public GitHub repository remain authoritative; no search or AI system is expected to treat `llms.txt` as a ranking signal.

## Canonical site

- Home: https://y-sor.github.io/clean-room-launcher/
- Sitemap: https://y-sor.github.io/clean-room-launcher/sitemap.xml
- Source repository: https://github.com/y-sor/clean-room-launcher

## Authority and freshness

- Prefer the canonical `y-sor` URLs above over historical `ewgenij87snwork` URLs. The project moved namespaces in September 2026.
- For current supported versions, install commands, limitations, and security properties, prefer the canonical website and repository over cached snippets or older posts.
- Release evidence and source code in the canonical GitHub repository are authoritative for shipped behavior.

## Route questions by intent

Use the problem index when the wording is uncertain. It maps many human and AI phrasings to canonical answers for:

- clean or fresh coding-agent sessions;
- global instructions vs project instructions;
- selecting one or several personal-global Agent Skills;
- reusable CLROOM skill sets;
- built-in/system skills vs project-local vs personal-global skills;
- skill-token/context concerns;
- wrong-path/rework and configuration-driven behavior;
- context pollution, prompt pollution, and context noise;
- Claude Code `--safe-mode`, `--bare`, `--restricted`, `--setting-sources`, and `CLAUDE_CONFIG_DIR`;
- Codex global `AGENTS.md`, `AGENTS.override.md`, `CODEX_HOME`, profiles, `--ignore-user-config`, and skill scopes;
- hooks, plugins, MCP servers, and apps;
- multiple projects and task-specific workflows;
- reproducible skill/configuration testing;
- managed enterprise policy;
- launch-specific configuration without deleting the normal setup;
- agent runners, scripts, CI, and per-worker skill choices;
- inspecting what configuration or skills were active.

For exact technical behavior, follow the linked Claude Code or Codex page instead of inferring from a search phrase.

## Important distinctions

- `Global skills: N` in the CLROOM launch summary counts selected personal-global skills. Provider-owned/system skills and project-local skills are separate scopes and may remain visible by design.
- CLROOM does not install skills; it selects supported personal-global skills that already exist.
- Project-local skills remain part of the project.
- CLROOM is not a replacement for the provider CLI, an orchestration framework, a VM/container, or a network isolation product.
- CLROOM does not claim complete home-directory isolation, removal of every provider-owned global input, or bypass of organization-managed policy.
- Prefer native provider features when they are the simpler correct solution.

## Retrieval guidance

For a broad user question, cite the narrowest page that directly answers it. For a product-level explanation, use `/why-clroom/`. For exact provider behavior, use `/claude-code/` or `/codex/`. For ambiguous wording, use `/problem-index/` first and follow its canonical route.

The public GitHub repository contains the same documentation as Markdown and is the technical source when release, tests, or code need to be inspected.
