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 A, and why

claude-setup scanned grade A with 0 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 8d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Claude Setup

Verify the local bootstrap before asking the shared runtime for a sanitized capability and authentication report.

Workflow

  1. Check that Node is discoverable using the host-native command: command -v node on POSIX shells or Get-Command node in PowerShell. Then run node --version. If Node is absent or the major version is below Node.js 20+, report the actionable prerequisite error and stop because the Node runtime cannot diagnose its own absence.
  2. Resolve <plugin-root>/scripts/claude-companion.mjs to an absolute path.
  3. Make exactly one runtime invocation. Runtime action: setup.
  4. Pass --cwd with the current workspace and --json as separate arguments. Use an argument array; never concatenate or interpolate values into a shell command.
  5. Explain the sanitized result and any repair steps without exposing raw auth output.

The runtime checks the installed CLI, supported flags, version, and claude auth status. A logged-in Claude.ai subscription is sufficient and does not require an API key. Anthropic API-key and supported enterprise provider authentication are also valid. Never print or persist credentials.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
