troubleshoot

troubleshoot is a skill for Claude Code, Codex from dinglebear-ai/cortex. It costs 29 tokens per session (1,823 once invoked), scanned C, original, AGPL-3.0.

Troubleshooting guidance for diagnosing failures in Cortex connections, logs, containers, and restart loops.

In plain words
What is it for?
It is for investigating connection failures, unavailable logs, unhealthy containers, and services that repeatedly restart.
Why use it?
It helps turn vague reports such as “the logs are not working” into checks for the likely cause, including missing logs or unhealthy containers.

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 C, and why

troubleshoot scanned grade C with 4 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 4d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

4. **Token roundtrip in bearer mode**: `curl -sS -X POST -H "Authorization: Bearer $CLAUDE_PLUGIN_OPTION_API_TOKEN" -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" -d '{"jsonrpc":"2.0

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

`ssh <host> "sudo journalctl -t rsyslogd -n 30 --no-pager"` — look for `omfwd` errors (DNS resolution, peer closed, EOF on TCP). Common patterns we've seen: stale forwarder pointing at a dead host, idle TCP timeout flapp

Reads agent configuration directoriesmediumAgent snooping

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

Read `~/.claude/settings.json`, find the `pluginConfigs` key that starts with `cortex@`, and inspect `options.server_url` — empty string is a known footgun (the `.mcp.json` substitution produces a literal `/mcp`). Check

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Run `curl -sS -o /dev/null -w '%{http_code}' "$CLAUDE_PLUGIN_OPTION_SERVER_URL/mcp"`.

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.

troubleshoot is a skill published in the GitHub repository dinglebear-ai/cortex (3 stars, last pushed today), licensed AGPL-3.0. It adds 29 tokens to every session and 1,823 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 4 findings (sends data to an external url, 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.
