troubleshooting

troubleshooting is a skill for Codex from badsectorlabs/ludus-skills. It costs 50 tokens per session (445 once invoked), scanned A, original, MIT.

A troubleshooting guide for Ludus, a system for deploying virtual computer labs. It helps investigate problems with deployments, networks, templates, WireGuard, Proxmox, and Ansible.

In plain words
What is it for?
Use it to inspect deployment status, errors, logs, templates, configuration, and testing-mode settings, then verify that the problem is resolved.
Why use it?
It gives a structured way to move from an error report to its likely cause and a checked fix, instead of guessing.

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

troubleshooting 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 10d 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

Ludus Troubleshooting

Use this skill to triage user-reported failures quickly, categorize errors, and provide targeted remediation steps.

Diagnostic Workflow

  1. Gather context and exact error output.
  2. Check range deployment status and recent errors.
  3. Review deployment logs for failure details.
  4. Identify the failure category using the known error catalog.
  5. Inspect the current range config for misconfigurations.
  6. Provide targeted fixes with concrete steps.
  7. Define clear verification steps to confirm recovery.

Key Diagnostic Information

When triaging, gather these in order of usefulness:

  • Range status — is the deployment running, failed, or complete?
  • Deployment errors — the most recent error output from a deploy.
  • Deployment logs — full log stream for tracing failure context.
  • Template status — are required templates built and available?
  • Range config — does the YAML match what the user intended?
  • Testing mode status — is testing mode active, and are network rules in effect?

Common Patterns

  • Network issues often trace back to dnsmasq or NAT bridge state.
  • Ansible failures often involve WinRM (Windows) or SSH reachability (Linux).
  • Domain join failures usually involve DNS ordering or timing.
  • Template failures are commonly ISO download or disk-space related.

References

  • Use references/common-errors.md for known errors, root causes, and fix procedures.
  • Use https://docs.ludus.cloud/docs/troubleshooting/client for client and CLI troubleshooting details.
  • Use https://docs.ludus.cloud/docs/troubleshooting/network/ and https://docs.ludus.cloud/docs/troubleshooting/wireguard/ for network and connectivity issues.
  • For uninstalling Ludus, direct users to the official guide at https://docs.ludus.cloud/docs/troubleshooting/uninstall rather than performing the steps yourself.
Files

What ships with it

2 files 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.
