Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00017 | $0.00453 |
| Opus 5.5 | $0.00007 | $0.00181 |
| Sonnet 5.5 | $0.00003 | $0.00091 |
| Haiku 4.5 | $0.00002 | $0.00045 |
Grade A, and why
erne-debug 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
/erne-debug — Systematic Diagnosis
You are executing the /erne-debug command. Use the performance-profiler agent for systematic bug diagnosis.
Process
Step 1: Reproduce
Define exact reproduction steps:
- Starting state
- Actions taken
- Expected behavior
- Actual behavior
- Environment (device, OS, Expo SDK version)
Step 2: Classify the Bug
| Category | Indicators | First Check |
|---|---|---|
| Crash | App terminates | Check Metro logs, Hermes stack trace |
| Render | Visual glitch, wrong layout | Check component tree, re-render count |
| State | Wrong data displayed | Check Zustand store, TanStack Query cache |
| Navigation | Wrong screen, broken back | Check Expo Router history, params |
| Performance | Jank, slow response | Check FPS, bundle size, memory |
| Network | Failed API calls | Check request/response, auth tokens |
| Native | Platform-specific issue | Check native logs (Xcode/Logcat) |
Step 3: Investigate
JavaScript layer:
# Check Metro bundler logs
# Search for errors/warnings in console output
# Add strategic console.log at suspected points
React layer:
- Component re-render tracking (React DevTools)
- Props/state inspection
- Effect dependency analysis
Native layer (if agent-device available):
- Screenshot current state
- Navigate through repro steps visually
- Capture native crash logs
Step 4: Fix & Verify
- Identify root cause
- Implement minimal fix
- Verify fix resolves the issue
- Check for regression (run related tests)
- Document what caused it and why

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.
- 8d ago First seen · 75 lines · 17 tokens per session scan A 0a856663f75a
erne-debug is a command published in the GitHub repository JubaKitiashvili/everything-react-native-expo (49 stars, last pushed 8d ago), licensed MIT. It adds 17 tokens to every session and 453 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-09.
