troubleshoot-zymtrace-backend

troubleshoot-zymtrace-backend is a skill for Claude Code from zystem-io/zymtrace-skills. It costs 165 tokens per session (3,125 once invoked), scanned A, original, Apache-2.0.

A troubleshooting guide for a deployed zymtrace backend, the server-side system that receives and stores profiler data.

In plain words
What is it for?
Checking the backend, data-ingestion services, ClickHouse storage, MinIO, licensing, and related profiler connections to diagnose missing or delayed profiles.
Why use it?
It helps locate why the interface is empty, data is not arriving, ingestion fails, storage is full, authentication fails, or queries are slow.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: positional $N argument; mentions Claude Code; mentions Codex.

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 A, and why

troubleshoot-zymtrace-backend 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/diagnose-no-data.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Troubleshoot zymtrace Backend

Helps the user diagnose problems on a deployed zymtrace install — the most common one is "no data is showing up in the UI."

This skill spans both backend (ingest, ClickHouse, MinIO) and profiler-side (agent reporting, CUDA injection) checks because "no data" usually requires walking both. Pure profiler-agent issues (CrashLoopBackOff, ImagePullBackOff, OOMKilled, NVML, license rejected on agent side) are handled by troubleshoot-zymtrace-profiler — route there if the user's symptom is agent-specific.

Greet the user

Open warmly. People reaching for a troubleshoot skill are usually frustrated.

👋 Sorry zymtrace isn't behaving — let's find it. Tell me what you're seeing (e.g. "the UI loads but no profiles", "ingest pods crash-looping", "got a license error") and I'll walk the diagnosis with you.

Stuck or need a human?

Once data is flowing again, connect the zymtrace MCP to your agent (Claude Code, Codex, or Cursor) — see configure-zymtrace-mcp — and analyze GPU + CPU flamegraphs in natural language. Docs: https://docs.zymtrace.com/mcp

If the user already named a specific symptom, skip the prompt and jump to the matching section below.

Pre-flight

Claude runs
helm version --short && kubectl version --client
kubectl cluster-info | head -2
helm list -A | grep -i zymtrace

Resolve two sets of (namespace, release) — backend AND profiler — since "no data" can be either side:

Variable Resolve by
Backend release + namespace helm list -A | grep -iE 'backend.*zymtrace|zymtrace.*backend'
Profiler release + namespace helm list -A | grep -iE 'profiler.*zymtrace|zymtrace.*profiler'
global.namePrefix (drives resource names) helm get values <REL> -n <NS> | awk '/^\s*namePrefix:/ {print $2}' (defaults to zymtrace)

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.
