Hermes Agent 4b8eba95a3 fix(guard): apply word normalization to the path arm, not just the name arm
The quote/escape handling added over rounds 1-6 was wired into the command
NAME reading only. The PATH reading one line below it still matched the raw
text, so every spelling the name arm had learned to see was invisible to the
checkout check: `"$HOME"/wt`, `${HOME}/wt`, `"${HOME}"/wt` and a quoted
literal home path all cleared a guard whose entire purpose is to refuse them.
An identifier is not one spelling, and this file has now proven that seven
times; the arms of the rule were audited one at a time, and the class survived
in the arm nobody looked at.

The two readings need the same quote and escape handling but differ in one
respect, so this is one state machine with two modes rather than a copy:
substitution flattening is correct for a name and wrong for a path, where an
expansion-capable `$HOME` must stay visible. In path mode a shell-LITERAL
dollar or tilde -- single-quoted, escaped, or a quoted tilde -- becomes an
internal nonmatching marker, so quote removal cannot manufacture a home
spelling the shell would never expand, and `"~/wt"` is no longer refused.

`home_re` treats the braces as the pair they are. `$HOME}` expands HOME and
appends a literal brace; `${HOME` is not an expansion at all. Admitting either
as `${HOME}` would invent a home path the shell never resolves.

Verified by oracle rather than by assertion: for each spelling, `printf` under
bash performs expansion and quote removal without executing, and the resulting
path decides the expected verdict. 24 spellings, 0 mismatched here; 6
mismatched at 3d0a882a, which is what makes this a fix and not a rewrite.
Fixtures 184 -> 198.

@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.
