Troubleshooting
| Issue | Cause | Solution |
|---|---|---|
| Non-mql5.com URL | Skill only supports mql5.com | Use other tools for non-mql5.com sites |
| Article not found | Invalid article ID or removed | Verify URL exists by visiting in browser |
| User ID not recognized | Wrong user ID format | Use numeric ID from profile URL or exact username |
| Empty extraction | Rate limiting or site change | Wait and retry, check for site structure changes |
| Permission denied | Working directory mismatch | Run from $HOME/eon/mql5-local directory |
| Batch too large | Too many articles requested | Limit batch size, use URL list file |
| Missing dependencies | Required tools not installed | Install curl, jq for extraction |
| Output encoding issues | Unicode in article content | Ensure UTF-8 output handling |
Post-Execution Reflection
After this skill completes, check before closing:
- Did the command succeed? — If not, fix the instruction or error table that caused the failure.
- Did parameters or output change? — If the underlying tool's interface drifted, update Usage examples and Parameters table to match.
- Was a workaround needed? — If you had to improvise (different flags, extra steps), update this SKILL.md so the next invocation doesn't need the same workaround.
Only update if the issue is real and reproducible — not speculative.
