healthcheck

healthcheck is a skill for Claude Code, Codex from kaivyy/kabot. It costs 67 tokens per session (2,408 once invoked), scanned A, a copy of healthcheck, MIT.

A host-security guide for machines running Kabot, such as laptops, workstations, Raspberry Pis, or VPS servers. It reviews exposure and helps align security settings with the user's risk tolerance.

In plain words
What is it for?
Security audits, firewall and SSH hardening, software-update checks, exposure reviews, backup checks, and scheduling recurring Kabot security checks.
Why use it?
It helps identify security risks without confusing Kabot's own checks with changes to the operating system. It also emphasizes approval, safe staging, and preserving remote access.

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

healthcheck 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 12d 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.

Kabot Host Hardening

Overview

Assess and harden the host running Kabot, then align it to a user-defined risk tolerance without breaking access. Use Kabot security tooling as a first-class signal, but treat OS hardening as a separate, explicit set of steps.

Core rules

  • Recommend running this skill with a state-of-the-art model (e.g., Opus 4.5, GPT 5.2+). The agent should self-check the current model and suggest switching if below that level; do not block execution.
  • Require explicit approval before any state-changing action.
  • Do not modify remote access settings without confirming how the user connects.
  • Prefer reversible, staged changes with a rollback plan.
  • Never claim Kabot changes the host firewall, SSH, or OS updates; it does not.
  • If role/identity is unknown, provide recommendations only.
  • Formatting: every set of user choices must be numbered so the user can reply with a single digit.
  • System-level backups are recommended; try to verify status.

Workflow (follow in order)

0) Model self-check (non-blocking)

Before starting, check the current model. If it is below state-of-the-art (e.g., Opus 4.5, GPT 5.2+), recommend switching. Do not block execution.

1) Establish context (read-only)

Try to infer 1–5 from the environment before asking. Prefer simple, non-technical questions if you need confirmation.

Determine (in order):

  1. OS and version (Linux/macOS/Windows), container vs host.
  2. Privilege level (root/admin vs user).
  3. Access path (local console, SSH, RDP, tailnet).
  4. Network exposure (public IP, reverse proxy, tunnel).
  5. Kabot gateway status and bind address.
  6. Backup system and status (e.g., Time Machine, system images, snapshots).
  7. Deployment context (local mac app, headless gateway host, remote gateway, container/CI).
  8. Disk encryption status (FileVault/LUKS/BitLocker).
  9. OS automatic security updates status. Note: these are not blocking items, but are highly recommended, especially if Kabot can access sensitive data.
  10. Usage mode for a personal assistant with full access (local workstation vs headless/remote vs other).

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.
