Round six of the same class: a program NAME is not one SPELLING. Two findings, and the second is one this change's own predecessor introduced. A FOURTH name consumer never went through the shared site. Checkout detection still recognized git by a raw whole-command regex, so `g"it" clone`, `g'it' clone` and `g\it clone` into $HOME were all allowed. `/usr/bin/git` blocked only because the raw text still happened to contain contiguous `git` — the same passing presentation that established nothing during the curl rounds. It now uses CMD_NAMES and NAME_PREFIX like the other three, so all four consumers share one definition of what a name looks like. Routing it through NAME_PREFIX also repaired an over-block the arm had carried from the start: the old regex found `git` INSIDE a longer word, so `mygit clone` and `gitfoo clone` were refused at every previous head. That is the mycurl and curl-wrapper class, and refusing it is how a guard gets routed around instead of repaired. The normalization itself was creating names the shell never runs. It deleted every backslash regardless of quote context, but a backslash inside single quotes is literal, so `'cu\rl' --config` names a program called cu\rl and was refused. The same holds inside double quotes before any character other than $, `, " or backslash. Both were false positives, and both were regressions — the pre-PR head allowed them. Quote removal and escape handling are different operations that were sharing one context-blind deletion pass. They are now a small state machine that follows the actual rule: outside quotes a backslash escapes the next character; inside single quotes everything is literal; inside double quotes a backslash is special only before $, `, " or backslash. Quote characters drop without splitting the word, and the substitution flattening that makes `$(which curl)` resolve to a bare name is unchanged. An over-block is not the safe direction. A guard that refuses legitimate work gets routed around rather than fixed, which is the same outcome as a bypass and arrives faster. Unchanged and still disclosed: names absent from the literal text — assembled from braces or variables — remain invisible to text matching, and `$((curl))` is over-matched at every head including the pre-PR one. Fixtures: 173 -> 184. Every one added here discriminates against the previous head1c3e79a9(8 fail there: 3 git bypasses, 5 over-blocks), and the positives also fail at the pre-PR headdf83a9ee. Suite green at head, bash -n and shellcheck clean, enumeration gate 55/38/18.
@mosaicstack/mosaic
CLI package for the Mosaic self-hosted AI agent platform.
Usage
mosaic wizard # First-run setup wizard
mosaic gateway install # Install the gateway daemon
mosaic config show # View current configuration
mosaic config hooks list # Manage Claude hooks
Headless / CI Installation
Set MOSAIC_ASSUME_YES=1 (or ensure stdin is not a TTY) to skip all interactive prompts. The following environment variables control the install:
Gateway configuration (mosaic gateway install)
| Variable | Default | Required |
|---|---|---|
MOSAIC_STORAGE_TIER |
local |
No |
MOSAIC_GATEWAY_PORT |
14242 |
No |
MOSAIC_DATABASE_URL |
(none) | Yes if tier=team |
MOSAIC_VALKEY_URL |
(none) | Yes if tier=team |
MOSAIC_ANTHROPIC_API_KEY |
(none) | No |
MOSAIC_CORS_ORIGIN |
http://localhost:3000 |
No |
Admin user bootstrap
| Variable | Default | Required |
|---|---|---|
MOSAIC_ADMIN_NAME |
(none) | Yes (headless) |
MOSAIC_ADMIN_EMAIL |
(none) | Yes (headless) |
MOSAIC_ADMIN_PASSWORD |
(none) | Yes (headless) |
MOSAIC_ADMIN_PASSWORD must be at least 8 characters. In headless mode a missing or too-short password causes a non-zero exit.
Example: Docker / CI install
export MOSAIC_ASSUME_YES=1
export MOSAIC_ADMIN_NAME="Admin"
export MOSAIC_ADMIN_EMAIL="[email protected]"
export MOSAIC_ADMIN_PASSWORD="securepass123"
mosaic gateway install
Runtime launchers
mosaic claude # Launch Claude Code with Mosaic injection
mosaic yolo claude # …with --dangerously-skip-permissions
mosaic codex | opencode | pi
mosaic claudex (EXPERIMENTAL)
Runs GPT models inside the Claude Code harness by pointing Claude Code at a
local claude-code-proxy that
translates the Anthropic Messages API to a ChatGPT-subscription (Codex OAuth)
backend. This is not Anthropic Claude — model behavior, tool use, and output
quality may differ. Intended for evaluation, not production delivery.
mosaic claudex # launch (prompts through the proxy readiness gate)
mosaic yolo claudex # …with --dangerously-skip-permissions
mosaic claudex --print "hello" # trailing args are forwarded to Claude Code
Prerequisite: the claude-code-proxy binary must be installed and
authenticated (claude-code-proxy codex auth …). mosaic claudex runs a
preflight that verifies the binary, the OAuth state (triggering a device re-auth
if needed), and a trusted local listener before launching; it fails closed
if the proxy cannot be brought up with a verified identity.
Isolation (never touches your real Claude state). claudex always launches
against an isolated CLAUDE_CONFIG_DIR (default ~/.config/mosaic/claudex/home).
The ambient CLAUDE_CONFIG_DIR is deliberately ignored, and a guard proves the
resolved dir can never be — or live under — the real ~/.claude. A claudex
session therefore cannot mutate your normal Claude Code config.
No token leakage. claudex never reads the proxy's credential file. Claude
Code is handed only ANTHROPIC_AUTH_TOKEN=unused pointed at the loopback proxy;
the entire credential-bearing env family (ANTHROPIC_*, AWS_*, GOOGLE_CLOUD_*,
GOOGLE_APPLICATION_CREDENTIALS, *_TOKEN, *_KEY, *_SECRET, …) is stripped
from the composed environment. The Bedrock/Vertex routing switches
(CLAUDE_CODE_USE_BEDROCK, CLAUDE_CODE_USE_VERTEX, and the _SKIP_*_AUTH
pair) are force-removed regardless of value — otherwise their mere presence
would route Claude Code to the real Anthropic API via AWS/GCP and bypass the
proxy. The proxy holds the real OAuth credential.
Model tiers (override via env).
| Tier | Env var | Default |
|---|---|---|
| primary (opus/sonnet) | ANTHROPIC_MODEL |
gpt-5.6-sol |
| small/fast (haiku) | ANTHROPIC_SMALL_FAST_MODEL |
gpt-5.6-luna |
Operator-provided values win over the defaults. Additional overrides:
MOSAIC_CLAUDEX_CONFIG_DIR (isolated config dir), ANTHROPIC_BASE_URL (proxy
endpoint).
Hooks management
After running mosaic wizard, Claude hooks are installed in ~/.claude/hooks-config.json.
mosaic config hooks list # Show all hooks and enabled/disabled status
mosaic config hooks disable PostToolUse # Disable a hook (reversible)
mosaic config hooks enable PostToolUse # Re-enable a disabled hook
Set CLAUDE_HOME to override the default ~/.claude directory.
