An interactive setup skill for installing or reconfiguring a model-guard status line. A status line is text shown in the agent interface while it works.

Use it to install or refresh the model-guard script, configuration, and status-line entry in the agent settings.

It collects display preferences and updates the required local files, while keeping a timestamped backup of the settings file.

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code

/plugin marketplace add ventusff/claude-model-guard

Claude Code

/plugin install model-guard

Made for: Claude Code.

Or install model-guard, the plugin that ships this one along with the rest of its 3 skills, 7 hooks.

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	$0.00076	$0.02214
Opus 5.5	$0.00030	$0.00886
Sonnet 5.5	$0.00015	$0.00443

Security

Grade C, and why

setup scanned grade C with 2 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

model-guard: interactive setup

You are installing (or reconfiguring) model-guard for this user: the statusline scripts and the auto-recovery hooks' configuration.

Plugin root: ${CLAUDE_PLUGIN_ROOT} (If the path above looks like an unexpanded shell variable instead of a real directory, locate the plugin root via claude plugin list --json or by finding */model-guard/scripts/statusline.sh under ~/.claude/plugins/.)

Target paths — use exactly these:

scripts: ~/.claude/model-guard/ (statusline.sh, lib.sh, text.sh)
config: ~/.claude/model-guard.conf
register: the statusLine key in ~/.claude/settings.json

Follow the steps in order. Keep your final report short.

1. Preflight (one Bash call)

command -v jq — required. If missing, stop and tell the user how to install it (sudo apt install jq / brew install jq / sudo pacman -S jq), then exit.
Read ~/.claude/settings.json: note the current statusLine (if any) and the model field (used for auto-detecting the expected model — no question needed).
Read ~/.claude/model-guard.conf if it exists (this run is then a reconfigure — mention the current values inside the question descriptions below).
Keystroke channel for auto-recovery, from this session's environment, first hit wins: TMUX + TMUX_PANE set → tmux; ZELLIJ_SESSION_NAME + a numeric ZELLIJ_PANE_ID set → zellij; KITTY_WINDOW_ID set and KITTY_LISTEN_ON set → kitty; KITTY_WINDOW_ID set but KITTY_LISTEN_ON empty → kitty without remote control (fixable, see step 3b); otherwise none.

2. Ask preferences (ONE AskUserQuestion call)

Question 1 — header "Language", band text language:

"Auto (Recommended)" — follow Claude Code's language setting, fall back to English
"English"
"中文"
"More…" — description: also available: 日本語 · 한국어 · Español · Français · Deutsch · Português; type one via Other (conf values: ja / ko / es / fr / de / pt)

Question 2 — header "Account", show the logged-in account email on the band (useful when juggling multiple accounts):

"Show (Recommended)"
"Hide"

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.

setup is a skill published in the GitHub repository ventusff/claude-model-guard (2 stars, last pushed 1mo ago), licensed MIT. It adds 76 tokens to every session and 2,214 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it C with 2 findings (asks for root, reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
