Jason Woltje 1af7ae4b7f W-F4/W-F6: mosaic store + mosaic fleet plugin
Two commands, and the seam between them is the point. `mosaic store` admits a
reviewed directory into ~/.mosaic/{plugins,skills} and entitles nobody.
`mosaic fleet plugin enable` writes one entry into one seat's profile.json and
copies nothing. A plugin reaching a seat therefore takes two deliberate acts,
and neither happens as a side effect of the other -- the same split adoption.ts
already documents.

Entries are `<name>@<version>` as one path segment, and admission has no flag to
skip the version. HARNESS-HOMES triage #8 specified `store/<name>/<version>`
with symlink pinning; that layout is unreachable from a profile as launch is
built today. `resolveManagedLinks` in fleet-launch-command.ts resolves a profile
entry as a single path segment and refuses a symlink there, and its STORE_ENTRY
charset admits `@` while rejecting `/`. Proven against the built CLI, not
assumed: a dry-run launch of a seat with [email protected] enabled plans
  .../agents/smoke/.claude/plugins/[email protected] -> .../.mosaic/plugins/[email protected]
This discrepancy is reported to the design owner rather than settled here.

Admission is `--as <name>@<version>`, not `--name` + `--version`. The first cut
used `--version` and a unit test could not see the problem: Commander's own
--version is on the program, so `mosaic store add … --version 1.2.0` printed the
CLI version and admitted nothing. Only an end-to-end run of the built binary
caught it. The regression test now registers under a program that sets a
version, which is the shape that fails.

`--live` is refused rather than accepted-and-ignored. An operator who asks for a
live change and gets a success message would reasonably believe the seat changed.

Not addressed here: launch composes `enabledPlugins` from the settings layers
only, never from profile.plugins, so an entitled plugin is linked into the seat
but not listed there. Reported separately.

Tests: 48 new (16 store module, 11 store command, 21 fleet plugin). Suite 1753
passed / 4 failed, the 4 being the mutator-gate acceptance failures already red
on origin/main. Root build 25/25.

@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.
