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 | $0.00030 | $0.01986 |
| Opus 5 | $0.00015 | $0.00993 |
| Sonnet 5 | $0.00006 | $0.00397 |
| Haiku 4.5 | $0.00003 | $0.00199 |
Grade A, and why
vx-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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 402 lines — stays where its author put it; the contents beside it link to each section on GitHub.
VX Troubleshooting Guide
Quick triage: Start with
vx doctorfor diagnostics. Usevx --debug <command>for detailed logs. Usevx cache cleanto clear corrupted state. Check exit codes (2=tool not found, 3=install failed, 4=version not found, 5=network error).
Common Issues
Installation Failures
Tool Download Failed
Symptoms: Failed to download <tool>: network error or Connection refused
Solutions:
# Enable CDN acceleration (China users)
vx config set cdn_acceleration true
# Use mirror
vx install node --mirror https://npmmirror.com/mirrors/node
# Retry with verbose output
vx install node --verbose --debug
# Check cache and retry
vx cache clean
vx install node
Checksum Mismatch
Symptoms: Checksum mismatch: expected X, got Y
Solutions:
# Clear corrupted download
vx cache clean
# Reinstall with fresh download
vx install node@22 --force
Permission Denied
Symptoms: Permission denied or Access is denied
Solutions:
# Check VX_HOME permissions
ls -la ~/.vx
# Fix permissions (Unix)
chmod -R u+rw ~/.vx
# Run with elevated permissions if needed
sudo vx install node # Not recommended, use user installation
Version Issues
Version Not Found
Symptoms: Version X not found for <tool>
Solutions:
# List available versions
vx versions node
# Use latest stable
vx install node@latest
# Use LTS version
vx install node@lts
# Check for typos
vx versions node | grep "20"
Version Conflict
Symptoms: Multiple versions installed, wrong version active
Solutions:
# List installed versions
vx list node --installed
# Switch to specific version
vx switch node@20
# Check which version is active
vx which node
# Remove conflicting versions
vx uninstall node@18
PATH Issues
Command Not Found
Symptoms: command not found: node after installation
Solutions:
# Verify vx shim directory is in PATH
echo $PATH | grep -o ".vx/bin"
# Add vx to PATH (add to shell config)
export PATH="$HOME/.vx/bin:$PATH"
# Or use vx directly
vx node --version
# Check shim exists
ls ~/.vx/bin/node
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.

vx-troubleshooting is a skill published in the GitHub repository loonghao/rez-next (25 stars, last pushed 3d ago), licensed Apache-2.0. It adds 30 tokens to every session and 1,986 once invoked, about $0.0002 per session on Opus 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 2026-09-02.
