In plain words

Why use it?
It handles the activation flow and reports when setup, a provider choice, or an error needs attention.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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.

Security

Grade B, and why

vertex scanned grade B with 1 finding 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

What it actually says

Context

  • Current state: !cat ~/.claude/vertex-provider/state.json 2>/dev/null || echo '{"active":false}'
  • Config exists: !test -f ~/.claude/vertex-provider.json && echo "yes" || echo "no"

Your Task

Activate the Vertex AI provider:

  1. If config doesn't exist, tell the user to run /vertex setup first

  2. Run the activation script and capture output:

node "${CLAUDE_PLUGIN_ROOT}/lib/cli/activate.js"

  1. If exit code is 2 (needs prompt): Parse the JSON output and use AskUserQuestion to present options:

    • Extract the reason, question, and options from the JSON
    • Present to user with AskUserQuestion
    • Based on selection:
      • If "anthropic": Run node "${CLAUDE_PLUGIN_ROOT}/lib/cli/deactivate.js" to switch
      • If "retry": Re-run the activation script
      • If "cancel": Tell user they remain on current provider
    • If selected provider needs setup, guide them through it

  2. If exit code is 0: Confirm Vertex AI is now active

  3. If exit code is 1: Show the error message to the user

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.
